Subject: [PATCH 01/84] fix(bin): report a Lavish source armed only after its
 listener is running (#5566)

* fix(bin): report a Lavish source armed only after its listener is running

Registration alone was treated as ready, so arm could succeed before anything was collecting from the board.

* no-mistakes(review): Guard Lavish arm launches, keep retire refusals, report live prior listener

* no-mistakes(review): Keep polling through window before reporting a still-live prior listener

* test: wait for a capture's claim to drop before the next arm

The result is stored before the runner exits, so a re-arm in that gap was meeting a live claim.

* no-mistakes(document): Record Lavish arm readiness evidence in verification doc

* no-mistakes(ci): Both failures were caused by this PR, and both are fixed with test-only edits. Lint 2 (ShellCheck SC2034): this branch removed the only use of `reply_id` (a `start "$reply_id"` call) from tests/fm-procevent.test.sh, which left the assignment at line 1450 unused. I deleted that assignment. It was the only `reply_id` in the file. ShellCheck is now clean on both test files. Behavior portable serial 4: the failing test was tests/fm-bearings-board.test.sh, in the check "registration consumed its answer before the any-origin binding existed". I reproduced it locally: the hold was still `state: queued` when the test checked it. - What must hold: the test's check that the hold is closed must run after the listener has captured the answer. - Why it broke: the test used a stand-in adapter that ran `fm-procevent.sh start` in the foreground after `arm`, so capture finished before build returned. On this branch, `arm` starts the listener itself in the background, so the real listener captures the answer and closes the hold a moment after build returns. - Fix: removed the now-redundant stand-in adapter, the copied runtime directory, and its extra environment variables. The test now runs the real build through the existing `run_board` helper and waits up to about 10s for the hold to reach `state: done`. The checks that follow are unchanged: `Resolution mode: answered` and the any-origin binding. - Other tests: this was the only test in the file that stood in for the adapter this way. The shard's other pure-contract-unit test (tests/fm-trace-context-lib.test.sh) passed unchanged. Verification: - tests/fm-bearings-board.test.sh passed 3 times in a row via bin/fm-test-run.sh, all 18 checks, about 53s per run. - tests/fm-procevent.test.sh was not rerun, because the lint fix only removed an unused assignment

 A terminal round is never re-armed: the board stays yours until you acknowledge it with `bin/fm-procevent.sh handled <source-id> <sequence>`, which retires it, and until then `retire` refuses the board too.
 Never arm a board that a live task hosts; follow the crew-hosted Lavish board contract in [`docs/configuration.md`](../../../docs/configuration.md#crew-hosted-lavish-review-boards).
 
-Registering a source is not the same fact as listening to it: arming records the source, and a separate runner still has to pick it up.
+Registering a source is not the same fact as listening to it.
+Lavish `arm` waits until this registration's listener is confirmed running and does not report ready without that evidence; other adapters still record the source for the watcher's next reconcile.
+When an earlier registration's listener still holds the board as the confirm window ends, Lavish `arm` prints `still-listening` instead of `armed`; that listener keeps serving the board, and the new registration takes effect only after you retire the source and arm it again.
 After arming by hand, confirm `bin/fm-procevent.sh list` reports that source as `live`, and run `bin/fm-procevent.sh reconcile` when it does not.
 Reconcile reports every launch that did not prove it took its claim within the confirm window as `failed=` and exits non-zero, so a source that cannot be started says so instead of looking armed, and it wakes you once per failure episode about it because the watcher discards that count; `start` does not fix that - if the source stays unowned, run `start` attached to read the runner's refusal, then check the source command and adapter binary the registration names, and if a later reconcile finds the source owned the episode closes on its own.
 A source `list` reports as `orphaned` is one reconcile will not relaunch, because something may still be polling it; reconcile wakes you once about it, and that wake's payload says which of two recoveries applies.

 That adapter, and only that adapter, retries the one exact transient response a cut-short listener returns while its marks remain available (`error: Lavish Editor poll response was interrupted` with `code: SERVER_ERROR`), up to 12 times with poll starts at least 5 seconds apart, so an internal retry never reaches the runner as a captured result.
 This start-to-start governor is a no-op after a normally blocking poll but caps an immediately returning poll under the shipped defaults independently of the owner lease and registration launch pacing.
 Real feedback, ended and missing sessions, any other `SERVER_ERROR`, and that same interruption still standing once the bound is spent are all captured and announced normally; `FM_LAVISH_POLL_RETRY_DELAY` is a bounded 1 to 60 second test override for the interval only, and the runner itself stays adapter-agnostic.

+An already-armed Lavish source keeps its registered listener command until it is retired and armed again, so retire the source, then arm it again to adopt this retry policy.
 
 ### Crew-hosted Lavish review boards
 
 A live task that hosts a Lavish board owns its listener, so firstmate must never arm that board.
 After opening the artifact as required above, the worker arms it with `bin/fm-procevent-lavish.sh arm <artifact.html> --for <task-id>` and never runs `lavish-axi poll` itself.
+`arm` prints `armed` only after the process-event owner confirms this registration generation's listener is running, and otherwise returns nonzero without that line.
+The confirmation is the same live claim or launch-stamp evidence `reconcile` already uses, bounded by `FM_PROCEVENT_LAUNCH_CONFIRM_SECONDS`, and a failed confirmation retires a source that never started unless `retire` refuses because something may still own it, in which case the registration stays for `reconcile` or a human.
+An earlier registration's listener that releases the board inside the confirm window lets the new registration start, and `arm` then reports `armed` as usual.
+When a live listener from an earlier registration of the same board still holds it when the window ends, `arm` exits zero with `still-listening` instead of `armed`, because that earlier listener keeps serving the board and the new registration takes effect only after the source is retired and armed again.
 The arm is refused unless that task id has valid, identity-matching endpoint metadata, because a board whose owner has no endpoint would collect feedback nobody can be told about.
 The registration persists as one task-owned source record, while each captured nonterminal round remains open until the worker re-arms and the existing handled marker acknowledges that round.
 Re-arm is that acknowledgement and nothing else: the board is armed once while no record exists, and a further arm by the same owner is refused unless an unacknowledged nonterminal round is waiting, so a generation already carrying a reply is never replaced before its listener posts it.

Subject: [PATCH 02/84] fix(bin): stop repeating unknown-wake escalations that
 were already delivered (#5599)

* fix(bin): acknowledge a delivered unknown-wake escalation

The same unrecognized wake was escalated again after it had already been handled, because delivery never recorded that identity.

* no-mistakes(review): Scope unknown-wake acknowledgements to one away session

* no-mistakes(review): Clear delivered digest when unknown-wake ack write fails

* no-mistakes(review): Limit unknown-wake suppression to acknowledged lines

* no-mistakes(document): List unknown-wake ack file among away-session artifacts

Subject: [PATCH 03/84] fix(bin): keep a stated default-key retraction from
 cancelling a keyless wait (#5587)

* fix(bin): keep a stated default retraction from cancelling a keyless wait

A resolved line that names the shared default decision bucket was closing the keyless live wait that only prints as that same key. Keyless self-retraction still closes the keyless wait.

* no-mistakes(review): Keep declared waits standing past foreign-key resolved lines

* no-mistakes(review): Bound declared-wait read and share one decision-key parser

* no-mistakes(document): Document supervisors' key-aware declared-wait read

 `bin/fm-crew-state.sh` owns the evidence guard that recognizes ended CI monitors after green checks, including cancelled runs and skipped rebase steps; a passed run alone never proves a forge merge.
 In the coarse runs-ledger fallback, which has no steps table and no ci log, a terminal failed record whose daemon an explicit `daemon status` probe proves down reports unknown as unverified instead: an instrument failure must never read as work failure.
 The same instrument rule covers the ledger-anchored continuation of a selected run whose head this copy cannot resolve: once the probe answers down, that still-executing record reports unknown as unverified, while a run parked at a gate keeps its gate and findings because an open decision stays open when the instrument dies, and a `needs-decision` or `blocked` event the crew observed first hand stays open with the unverified record named as the reason rather than superseded by it.
-Only when no matching run exists does it consult semantic busy state; exact busy reports working, exact idle permits fallback to the log's resolved current declaration - the newest decision the fold still holds open, otherwise the latest recognized event - when its verb maps to a recognized run-state, and unknown or a dead pane stays unknown instead of trusting a stale log.

 Decision-only events such as `resolved` never become current state or leak their prose into the current-state detail.
 In that status-log fallback, a declared external wait reports the distinct `paused` state with its reason.

 The watcher and daemon share `bin/fm-classify-lib.sh` for captain-relevant status verbs, declared-wait vocabulary (a `paused:` external wait and a verified `captain-held` transfer alike, through one combined predicate), and status-scan primitives.
 Terminal verbs remain captain-relevant, while a nonterminal progress verb cannot become terminal merely because its prose contains a legacy free-text token such as `merged`; bare legacy free-text lines remain compatible.
 The shared latest-event read takes the most recent line that leads with a recognized verb or legacy token, so continuation prose and trailing blank lines after a multi-line record cannot hide a declared wait.
+Both supervisors decide a declared wait through the library's declared-wait read rather than that latest event, so a later `resolved` line for a different phase key - including an `fm-send --resolve-key default` answer to a keyless decision - does not end a standing keyless or keyed `paused:` wait, while a resolved line for the wait's own key or any other later event still does.
 Both supervisors classify the status bytes appended since they last classified that log, never its last line alone, and report every actionable event through the captured endpoint before committing that position.
 The watcher's `.seen-*` and `.hb-surfaced-<task>` markers and the daemon's `.subsuper-seen-status-<task>` marker independently track reported file state and successfully classified position, so an unchanged unreadable state reports once without advancing past unread content, while a changed state retries and an unusable position re-reads the whole log.
 A keyed `needs-decision` or `blocked` transition accepted by the whole-file decision fold is retired only when that fold retires it - an explicit close for its exact key, or a terminal declaration by the ship or scout that owns the log - while a reserved-key transition the fold rejects surfaces as a reconciliation signal without becoming an open decision.

Subject: [PATCH 04/84] fix(bin): terminate a remote job worker that lost
 ownership on TERM (#5544)

* fix(bin): terminate a remote job worker that lost ownership when it receives TERM

A serving worker whose lock directory is gone can no longer quarantine shutdown, and resuming service publishes a false ready heartbeat. Exit after stopping only that worker's own command tree, without removing a replacement owner's lock.

* no-mistakes(review): Check worker lock ownership before publishing shutdown quarantine

* no-mistakes(document): Correct worker shutdown comment on replacement-owned lock

* fix(bin): keep an ousted remote job worker off the replacement quarantine

Shutdown can lose the lock after the first ownership check and before it
writes or clears quarantine. Bind both operations to the directory object
this process still owns so a replacement's quarantine stays untouched.

* no-mistakes(review): Make ousted-worker shutdown test reliably reach quarantine clear

* no-mistakes(document): Reattach worker_shutdown doc comment to its function

* no-mistakes(ci): Fixed the failing check (Behavior portable serial 7) with a test-only change to the stall test in tests/fm-remote-job.test.sh. Product code is unchanged; no other test changed. Cause: after the decoy dies, both workers run the same check-exists, read, delete sequence on the job records. On the CI runner the replacement deleted a record between the ousted worker's check and its read. The ousted worker exited 125, and because the file runs under set -e the unguarded `wait` ended the test with 125. The exit trap then killed the replacement, which produced the "Killed" line. Reproduction: a temporary 0.3 s delay between the check and the read, applied to the ousted worker only, made the committed test fail exactly as in CI (exit 125 and the "Killed" line). The new test passed with the same delay. The delay is reverted, along with a similar debug hook that the timed-out attempt had left in bin/fm-remote-job-worker.sh. Test changes: - The replacement is frozen (and confirmed stopped) before the decoy is killed and resumed only after the ousted worker exits, so only one worker touches the job records at a time. - The ousted worker is stopped only once its quarantine exists and its lane is reaped, which places it inside its stop loop. - Every fixed poll loop is now a wait on a named condition with a 30 s deadline and an explicit failure message. Exit detection also handles zombies. - The exit trap kills and waits for the decoy and both workers on every path. - A non-zero exit from the ousted worker now fails with its exit code and stderr instead of silently ending the file. The test still proves that the resumed ousted worker exits 0 and leaves the replacement's lock, quarantine contents and quarantine inode unchanged. Verification: the full test file passed four times on its own and three times under nice -n 10 with four busy-loop CPU hogs; bin/fm-lint.sh passes. Changes are not committed

* no-mistakes(ci): I fixed the failing check (Behavior portable serial 7) by changing only the stall test in tests/fm-remote-job.test.sh. Product code is unchanged. **What failed:** "an ousted worker in shutdown leaves the replacement quarantine untouched" failed on CI with the ousted worker exiting 125 ("could not stop the active command tree"). **Why:** during shutdown, the worker retries the still-running decoy command group a fixed 100 times, 0.01 s apart, then gives up and exits 125. The test tried to freeze the worker partway through those retries by sending SIGSTOP from outside. On a slow runner the retries ran out before the stop arrived, so the worker had already given up. The invariant is that the test must hold the ousted worker inside that retry loop until the replacement owns the lock. That was the only place the test depended on timing. The other waits already watch for a named state change with a 30 s deadline. **Fix:** - The ousted worker now starts with a small `sleep` wrapper at the front of its PATH, and the SIGSTOP race is gone. - The wrapper only holds a `sleep` called directly by that worker's own process (it checks its parent pid against a hold file) while its quarantine file exists. - The only such `sleep` is the first retry in the shutdown stop loop, so the worker waits there as long as needed. - The wrapper writes a marker when it starts holding. The test waits for that marker, then hands the lock to the replacement, freezes the replacement, and kills the decoy. - The test releases the worker by deleting the hold file. Deleting the whole temp directory also releases it, so a failed run cannot leave the wrapper looping. - A process leak: the test overwrites the job's command-group record with the decoy, so no worker ever stopped the job's real command. `fm-hold-job.sh` and its `sleep 30` stayed running for up to 30 s after the test. The test now records that group before overwriting it and kills it at the end of the test and in the exit cleanup. - The test still asserts the same things: the ousted worker exits 0, and the replacement's lock, quarantine contents and quarantine inode are unchanged. **Verification:** - The full file passed twice on its own, twice under `nice -n 10` with six busy-loop CPU hogs, and twice more after the leak fix. - `pgrep` found no leftover processes afterwards. - With the worker from just before the fix commit (cf45cb6^), the test still fails with "the ousted worker wrote or cleared the replacement quarantine during shutdown", so it still proves the fix. - `bin/fm-lint.sh` passes. - I did not reproduce the CI failure locally. The cause comes from the fixed retry limit and the CI error message. The changes are not committed

* no-mistakes(ci): I changed only the stall test ("an ousted worker in shutdown leaves the replacement quarantine untouched") in tests/fm-remote-job.test.sh. Product code is unchanged, and so is every other test. **Invariant:** the pid written to the job's group record must be a process-group leader whose group dies when that one process is killed. Otherwise the worker's bounded stop loop never sees the group die, gives up, and exits 125 ("could not stop the active command tree") before it reaches the lost-ownership exit. The decoy is the only place in this test that depends on this. **Fix:** - The decoy used to be `set -m; sleep 30 &`. It now starts as `perl -MPOSIX=setsid -e 'setsid() >= 0 or exit 1; exec @ARGV' sleep 30 &`, which gets its own session and group without shell job control. tests/fm-procevent.test.sh already uses the same idiom. - The test now waits, with the file's usual 30 s deadline and a named failure, until `ps -o pgid=` of the decoy equals its pid before writing it into the group record. This way the worker can never read the record before `setsid` has run. - The existing steps are unchanged: the test kills the decoy, reaps it with `wait` before releasing the hold file, and the exit trap still kills and reaps the decoy and both workers. - The assertions are unchanged: the ousted worker exits 0, and the replacement's lock pid, quarantine text and quarantine inode stay the same. **Cleanup:** I reverted a debug `printf` hook that the timed-out previous attempt had left in bin/fm-remote-job-worker.sh, and deleted its untracked `.tmp-repro/` directory. Neither was committed. **Verification:** - The full tests/fm-remote-job.test.sh passed twice normally and once under `setsid -w` with stdin from /dev/null (no controlling terminal). - `bin/fm-lint.sh` passes. - No leftover `sleep 30` processes afterwards. **Not reproduced:** I could not reproduce the CI failure locally. On this host `set -m` made the decoy its own group leader even without a controlling terminal, so the cause on the runner is not confirmed. The change removes the test's reliance on shell job control, as the user asked. Changes are not committed

* no-mistakes(ci): I changed only the stall test ("an ousted worker in shutdown leaves the replacement quarantine untouched") in tests/fm-remote-job.test.sh. Product code is unchanged, and so is every other test. **Invariant:** the group record the ousted worker checks in its stop loop must stay the job's own command group, and the test must stop that group before it releases the hold. Otherwise the bounded retry keeps seeing a live group, gives up, and exits 125 ("could not stop the active command tree") before it reaches the lost-ownership exit. The test overwrote this record in one place (the decoy) and stopped the group in one place (killing the decoy); both are changed. **Fix:** - I removed the setsid decoy and the overwrite of `.claim/group`. The record keeps the job's real command group, which the test still saves as `STALL_JOB_GROUP`. - The two-line `group_start` stays. It is still needed: without it the worker kills the real group on its first pass, before the replacement takes over, so the hold would never matter. - The `sleep` wrapper that holds the worker at its first stop-loop retry is unchanged. - After the replacement owns the lock, its quarantine is planted and it is frozen, the test runs `kill -KILL -- -$STALL_JOB_GROUP`. It then waits, with the file's usual 30 s deadline and a named failure, until `kill -0` on the group fails. Only then does it remove the hold file. The worker therefore always sees its own command already stopped and never races its retry budget. - The exit trap still kills the saved command group if the test fails. It can't `wait` on that group because the group is not a child of the test shell. The decoy variable and its cleanup entry are gone. - The assertions are unchanged: the ousted worker exits 0, and the replacement's lock pid, quarantine text and quarantine inode stay the same. **Verification:** - The full tests/fm-remote-job.test.sh passed twice normally. - It passed once under `setsid -w` with stdin from /dev/null (no controlling terminal). - It passed once under `nice -n 10` with six busy-loop CPU hogs. - With the worker from before the fix (cf45cb6^), the test still fails with "the ousted worker wrote or cleared the replacement quarantine during shutdown", so it still proves the fix. - No `fm-hold-job` or `sleep 30` processes were left afterwards. - `bin/fm-lint.sh` passes. **Not reproduced:** I couldn't reproduce the CI failure locally; the decoy version also passed on this host. So I can't confirm why the decoy group stayed alive on the runner. The new wait turns any leftover live group into a clear named failure instead of an exit 125. The changes are not committed

* fix(bin): keep a dead command group dead on bash 5.2

A bare return inside the liveness check drops the failing kill status when the check runs in a conditional, so shutdown keeps treating a stopped group as alive and exits 125.

* no-mistakes(review): Use bash 3.2 fd syntax and fix trap return comments

+| What you want to configure | Start here |
+| --- | --- |
+| Firstmate's code, private files, or project location | [FM_HOME](#fm_home) and [operational home layout](#operational-home-layout-and-state) |
+| Task windows and worker tools | [Runtime backend](#runtime-backend-configbackend--fm_backend) and [harness support](#harness-support) |

+
+## FM_HOME
+
+`FM_HOME` selects the operational home for one firstmate instance.
+
+| Location | What it contains | Default relationship |
+| --- | --- | --- |
+| Firstmate repo root | Shared code, including the scripts in this repo's `bin/` | Most scripts also use this as the operational home when `FM_HOME` is unset. |
+| Operational home | Private `state/`, `data/`, `config/`, and `projects/` | Selected by `FM_HOME`. |
+| Projects directory | Local project clones | Under the operational home; `FM_PROJECTS_OVERRIDE` can select a different directory for tests and specialized harness setup. |
+
+When `FM_HOME` is unset, most scripts use the repo root as the home.
+When it is set, scripts still run from this repo's `bin/`, while `state/`, `data/`, `config/`, and `projects/` come from `$FM_HOME`.
+
+### Root and directory overrides
+
+`FM_ROOT_OVERRIDE` overrides the firstmate repo root used by scripts, including the primary checkout watched by the worktree-tangle guard.
+When `FM_HOME` is unset, it also behaves as the old whole-root override.
+
+`bin/fm-send.sh` requires `FM_HOME` to be set before resolving a target.
+Unlike most scripts, it does not use the general fallback, because a steer must not silently resolve against the wrong home.
+These variables override individual operational directories for tests and specialized harness setup:
+
+| Variable | Directory selected |
+| --- | --- |
+| `FM_STATE_OVERRIDE` | Runtime state |
+| `FM_DATA_OVERRIDE` | Durable private records |
+| `FM_PROJECTS_OVERRIDE` | Local project clones |
+| `FM_CONFIG_OVERRIDE` | Local configuration |
+
+### Relative paths and lifecycle safety
+
+Before `fm-brief.sh`, `fm-spawn.sh`, or `fm-afk-launch.sh` saves a path or passes it to another process, it handles each applicable `FM_HOME`, `FM_STATE_OVERRIDE`, or `FM_DATA_OVERRIDE` directory as follows:
+
+- Resolve relative directories against the caller's working directory.
+- Preserve accepted absolute spellings unchanged.
+- Reject an unresolvable relative directory and name the offending variable.
+
+`fm-spawn.sh` additionally rejects control bytes in those raw directory inputs before shell or filesystem normalization can change which path the backlog gate checks.
+Lifecycle access to a backlog, task record, or pending-close record must resolve within its configured data or state root, and a final-component symlink is refused even when its target remains within that root.
 
-The shared orchestrator behavior lives in [`AGENTS.md`](../AGENTS.md) - edit it like any prompt when the fleet is empty, or dispatch shared-repo edits to a crewmate while tasks are in flight.
+Bootstrap applies the same relative `FM_HOME` resolution only when embedding that home in the generated Relay poll shim.
+Other transient consumers retain their existing shell-relative behavior.
+
+### Backend labels and containers
+
+| Backend | Effect of the operational home |
+| --- | --- |
+| herdr | `FM_HOME` determines the adapter's workspace label. |
+| zellij | `FM_HOME` determines the readable home prefix in visible tab titles, but does not split containers; use `FM_ZELLIJ_SESSION` for a separate session; the full home label also includes a short hash of the resolved `FM_ROOT` path. |
+| cmux | `FM_HOME` determines the default config path and readable home prefix in workspace titles; `FM_CONFIG_OVERRIDE` overrides where `config/cmux-socket-password` is read; the full home label also includes a short hash of the resolved `FM_ROOT` path; there is no per-home container split. |
 
 ## Operational home layout and state
 
-This section is the single owner of the top-level operational-home layout; producer script headers and their help own exact child-file fields and mutation contracts.
-The tracked code root contains the shared instruction, skill, documentation, workflow, and `bin/` surfaces, while each effective `FM_HOME` contains private operational directories.
-`data/` holds durable private fleet records such as the project and secondmate registries, captain preferences, optional shared captain preferences, learnings, backlog, briefs, scout reports, and explicitly installed content-addressed extension packages under `data/extensions/packages/`.
-`state/` holds runtime records such as task metadata, append-only status events, endpoint signals, watcher and wake-queue coordination, inactive terminal-outcome receipts under `state/terminal-outcomes/`, enabled extension working namespaces under `state/extensions/`, away-mode state, generated Relay artifacts, parent-side remote ledger copies under `state/secondmate-summary-cache/`, one-shot Bearings reconcile requests under `state/reconcile-notify/`, private secondmate config-reread generations with their retry and quarantine state, per-task steering-inbox records under `state/<id>.inbox/` (`bin/fm-task-inbox-lib.sh`), and parent-owned secondmate pending-reply records under `state/pending-replies/` (`bin/fm-pending-reply-lib.sh`).
-`config/` holds local gitignored operating choices, including explicit extension bindings under `config/extensions.d/`, and `projects/` holds the local project clones that Firstmate reads but changes only through the narrow guarded and concrete captain-approved exceptions in `AGENTS.md`.

+
+`data/` holds durable private fleet records:
+
+- Project and secondmate registries.
+- Captain preferences and optional shared captain preferences.
+- Learnings, backlog, briefs, and scout reports.
+- Explicitly installed content-addressed extension packages under `data/extensions/packages/`.
+

+
+- Task metadata, append-only status events, and endpoint signals.
+- Watcher and wake-queue coordination, away-mode state, and generated Relay artifacts.
+- Inactive terminal-outcome receipts under `state/terminal-outcomes/`.
+- Enabled extension working namespaces under `state/extensions/`.
+- Parent-side remote ledger copies under `state/secondmate-summary-cache/`.
+- One-shot Bearings reconcile requests under `state/reconcile-notify/`.
+- Private secondmate config-reread generations with their retry and quarantine state.
+- Per-task steering-inbox records under `state/<id>.inbox/` (`bin/fm-task-inbox-lib.sh`).
+- Parent-owned secondmate pending-reply records under `state/pending-replies/` (`bin/fm-pending-reply-lib.sh`).
+
+`config/` holds local gitignored operating choices, including explicit extension bindings under `config/extensions.d/`.
+
+`projects/` holds local project clones.
+Firstmate reads these clones, but changes them only through the narrow guarded and concrete captain-approved exceptions in `AGENTS.md`.
 Untracked files and directories whose names begin with `scratchpad` are also gitignored, so temporary scratch does not make porcelain-based secondmate sync guards treat a home as dirty.
 
-`bin/fm-spawn.sh` owns the base task-metadata fields it emits, while the runtime-backend section below owns backend-specific fields and selector interpretation.
-`bin/fm-contributions.sh` owns durable published-contribution records under each task, observation bounds, equivalent triage-label configuration, and the authenticated contribution check.
-The producing PR and Relay helpers own the fields they append, [`bin/fm-classify-lib.sh`](../bin/fm-classify-lib.sh) owns status-event vocabulary, optional emission-time syntax, and legacy unknown-time handling, and `bin/fm-crew-state.sh` owns current-state reconciliation.
-The [`bin/fm-fleet-snapshot.sh` header](../bin/fm-fleet-snapshot.sh) owns the snapshot's event-time and age fields, including secondmate parent-event projections.
-Wake, watcher, away-mode, and Relay-specific state mechanics remain with their named scripts and reference sections rather than being duplicated into one exhaustive state tree here.

 ## Calm preference (config/calm)
 
-The Pi Calm extension and the Claude Code Calm mod share the captain's home-local presentation choice in gitignored `config/calm` under the effective Firstmate home, so one `/calm` choice applies on either harness.
-Both resolve that home from `FM_HOME`, then `FM_ROOT_OVERRIDE`, then the tracked code root derived from their own path under it, or use `FM_CONFIG_OVERRIDE` as the config directory outright when that test and specialized-setup override is present.
-The values they write are `on` and `off`, each followed by one newline; an absent, unreadable, or unrecognized value defaults to off.
-`max` is the legacy value written by a removed third presentation level whose behavior is now ordinary Calm, and it is still read as `on`, so a home upgraded from it keeps Calm on rather than dropping to off.
-Each `/calm` command persists the new choice before changing live presentation, so a failed write leaves the current choice unchanged rather than claiming persistence; Pi replaces the file atomically, while the Claude Code mod writes it through the plugin API's plain file write.
+The Pi Calm extension and the Claude Code Calm mod share the local, gitignored `config/calm` preference under the effective Firstmate home.
+One `/calm` choice therefore applies on either harness.
+Both resolve the home in this order: `FM_HOME`, `FM_ROOT_OVERRIDE`, then the tracked code root derived from their own path under it.
+When `FM_CONFIG_OVERRIDE` is present for tests or specialized setup, it selects the config directory directly.
+
+### Values and default
+
+| Value or file state | Result |
+| --- | --- |
+| `on` | Calm on. |
+| `off` | Calm off. |
+| Absent, unreadable, or unrecognized | Defaults to off. |
+
+Both written values end with one newline.
+`max` is a legacy value from a removed third presentation level.
+Its behavior is now ordinary Calm, so it is still read as `on`.
+A home upgraded from `max` keeps Calm on rather than dropping to off.
+
+### Saving and reloading the preference
+
+Each `/calm` command saves the new choice before changing live presentation.
+A failed write leaves the current choice unchanged and is not reported as a saved preference.
+Pi replaces the file atomically; the Claude Code mod uses the plugin API's plain file write.
 The Pi extension reloads this preference on every Pi `session_start`, including startup, new, resume, fork, and reload reasons.
-The Claude Code mod likewise reloads it on every `session.start`, including same-process session replacement, and also loads it lazily before any row that can draw ahead of that event, including during `claude --continue` restoration.
+
+The Claude Code mod reloads it on every `session.start`, including same-process session replacement.
+It also loads the preference lazily before any row that can draw ahead of that event, including during `claude --continue` restoration.
 This preference is local to each Firstmate home and is not part of secondmate inherited configuration.
 
 ## Pi supervision branch
 
-On a Pi primary, an in-process supervision branch handles eligible task-local wake rows and selected heartbeat reviews while keeping main-only rows on the captain-facing path; [docs/pi-supervision-branch.md](pi-supervision-branch.md) owns its conversation lifecycle, row eligibility, mixed-queue dispatch, heartbeat routing, and pre-drain recheck.
+On a Pi primary, an in-process supervision branch handles eligible task-local wake rows and selected heartbeat reviews.
+Main-only rows stay on the captain-facing path.
+[docs/pi-supervision-branch.md](pi-supervision-branch.md) defines its conversation lifecycle, row eligibility, mixed-queue dispatch, heartbeat routing, and pre-drain recheck.
 Supervision is default-on: once a Pi primary session owns this home's fleet lock, the branch is eligible for every task with no captain grant file required.
-A genuinely no-op heartbeat is absorbed in bash and never reaches Pi, and every watcher-failure alarm stays on the captain-facing main path.
-A broken branch still falls back to today's wake-to-main path in both postures, and the legacy `state/.afk` daemon flag means nothing on Pi.
-While the away-posture record `state/.afk-contract` exists the branch takes every actionable row, no processing turn opens on the parked main, and main's standing authority relocates to the branch through the guarded scripts, each keeping its own gate; [docs/pi-supervision-branch.md](pi-supervision-branch.md#postures) owns that posture.
-While attended the branch's role stays bounded exactly as the captain-approved architecture set it: it cannot merge a PR, land local work, freshly spawn, or answer a decision, and every existing captain gate remains unchanged in either posture.

+Bash absorbs a genuinely no-op heartbeat before it reaches Pi.
+Every watcher-failure alarm stays on the captain-facing main path.
+If the branch breaks, wakes still fall back to main in both postures.
+The legacy `state/.afk` daemon flag has no effect on Pi.
+
+### Attended and away authority
+
+While the away-posture record `state/.afk-contract` exists:
+
+- The branch takes every actionable row.
+- No processing turn opens on the parked main.
+- Main's standing authority moves to the branch through the guarded scripts, each retaining its own gate.

+While attended, the branch cannot merge a PR, land local work, freshly spawn, or answer a decision.
+These are the bounds set by the captain-approved architecture.
+Every existing captain gate remains unchanged in either posture.
 Homes on other primary harnesses do not load the Pi branch extension; shared per-task lease behavior is owned by `bin/fm-lease-lib.sh`.
+
 `AGENTS.md`'s `state/` inventory routes the branch's runtime files to their format and lifecycle owners.
-While attended, a captain-facing (verdict `captain`) branch outcome persists as one exact, sequence-keyed visible transcript entry and then opens one sequence-keyed processing turn on main, which stays open until main acknowledges that sequence through its `fm_branch_processed` tool; while away, the entry persists but processing waits until the record is archived.
+
+### Outcome delivery and acknowledgement
+
+While attended, a captain-facing branch outcome (verdict `captain`) is saved as one exact visible transcript entry keyed by sequence.
+It then opens one processing turn on main for that sequence.
+The turn stays open until main acknowledges the sequence through its `fm_branch_processed` tool.
+While away, the entry is saved, but processing waits until the away-posture record is archived.
 The branch prompt's "Verdict: routine or captain" section owns the distinction between captain-facing, unsolicited routine, and unchanged-review outcomes.
+
 The generated [Pi supervision protocol](supervision-protocols/pi.md) owns main's event ownership, acknowledgement duty, and conversational treatment for merged outcomes, while the persisted entry itself owns captain visibility.
 A no-change heartbeat outcome explicitly reported with `task=fleet` and `silent=true` is delivered silently with no rendered note, while every other routine outcome still appends a rendered, sailboat-prefixed note.
 
 ## Pi supervision branch model and effort (config/supervision-branch-model, config/supervision-branch-effort)
 
-Supervision is an easier job than the captain's own conversation, so the branch can run on a cheaper model than main.
-It is also an easier job than the captain's own conversation needs reasoning for, so the branch can run at a shallower effort than main as well.
+The branch can run on a cheaper model than main because supervision is an easier job than the captain's own conversation.
+It can also use a lower reasoning effort because supervision needs less reasoning than that conversation.
+
+### Choose a model and effort
+
 The Pi `/supervision-model` command settles both in one flow: it opens a selector over the models that Pi reports with configured credentials and that this home's stored credentials let the isolated supervision branch resolve, plus a first "Follow main" entry, and then a second picker for the branch's reasoning effort.
 In Pi's terminal TUI, the model step uses Pi's bounded scrolling list with its input and fuzzy filtering primitives, the same list primitive Pi's `/model` picker scrolls: typing filters the entries, "Follow main" stays the first entry whenever it still matches, and a long catalog scrolls inside the dialog instead of running off the terminal.
+
 The non-TUI RPC, JSON, and print modes have no custom-component surface and keep Pi's generic selector without search, where terminal overflow does not apply.
 The effort list is a handful of levels and stays on Pi's plain selector dialog.
+
 Both picks change the supervision branch alone and never the captain's own conversation model or effort.
-It persists the model pick in gitignored `config/supervision-branch-model` and the effort pick in gitignored `config/supervision-branch-effort`, both under the effective Firstmate home, resolved from `FM_HOME`, then `FM_ROOT_OVERRIDE`, then the tracked code root derived from the extension path, or under `FM_CONFIG_OVERRIDE` when that test and specialized-setup override is present.
-Firstmate keeps no model catalog of its own; the list is the intersection of what Pi reports when the picker opens and what a fresh isolated branch runtime can run.
+
+### Saved settings and available models
+
+The command saves the model pick in gitignored `config/supervision-branch-model` and the effort pick in gitignored `config/supervision-branch-effort`.
+Both live under the effective Firstmate home, resolved in this order: `FM_HOME`, `FM_ROOT_OVERRIDE`, then the tracked code root derived from the extension path.
+When `FM_CONFIG_OVERRIDE` is present for tests or specialized setup, it selects the config directory directly.
+Firstmate keeps no model catalog of its own.
+The list is the intersection of what Pi reports when the picker opens and what a fresh isolated branch runtime can run.
+
 A provider that exists only because an extension registered it inside the captain's session, such as pi-devin-auth's `devin`, is offered and can be pinned or followed like any other; [pi-supervision-branch.md](pi-supervision-branch.md#cost-model-and-the-byte-stable-prefix) owns how that registration reaches the isolated branch runtime.
 Stored OAuth and API-key credentials retain their native credential type because Firstmate never copies, converts, installs, or overwrites credentials for the branch runtime.
-The file holds one `<provider>/<model-id>` line followed by one newline, split at the first `/` so a provider-qualified model id such as `openrouter/anthropic/claude-sonnet-4-5` survives intact.
-An absent, unreadable, or unparseable file means no pin, and the branch then follows main's own current model, applied explicitly and live whenever main changes models mid-session.
+
+### Model file format and default
+
+The model file holds one `<provider>/<model-id>` line followed by one newline.
+Parsing splits at the first `/`, so a provider-qualified model id such as `openrouter/anthropic/claude-sonnet-4-5` survives intact.
+An absent, unreadable, or unparseable file means no pin.
+The branch then follows main's current model, applied explicitly and live whenever main changes models mid-session.
+
+### Following a native Codex model
+
 When main uses `codex-native`, following main explicitly selects the same model through ordinary Pi's `openai-codex` provider, so the background branch owns an independent Pi conversation.
 If that ordinary Pi model is unavailable, the branch refuses to build and returns the notification to main; it never inherits the main native thread or silently selects a different model.
+
 Picking "Follow main" under a `codex-native` main reports that same `openai-codex` model, or that same refusal, because the command and the branch build share one follow rule.
 A `codex-native` branch pin is refused and excluded from the picker.
+
+### Applying and changing a model pin
+
 A valid pin wins over main and remains unaffected by main's model changes.
 Picking "Follow main" removes the file, and the command writes a pin at mode `0600` and replaces it atomically so a failed write leaves the current choice unchanged rather than claiming persistence.
-The file's current state decides the branch model on every branch build - the new conversation each main session start opens and the reopen after a model or effort change inside one session - and it overrides Pi's restore of whatever model a reopened branch session recorded, so the choice survives all of them.
+
+The file decides the branch model on every build: the new conversation opened at each main session start, and a reopen after a model or effort change within a session.
+It overrides the model Pi would otherwise restore from the reopened branch session, so the choice survives both cases.
 That override is what keeps "Follow main" honest: a branch conversation that ran under an earlier pin still records that model, so clearing the file explicitly applies main's model rather than letting the reopened session restore the old one.
-For ordinary Pi providers, only when main's own model is unknown, or this home's stored credentials cannot run it in the isolated branch runtime, does an unpinned build fall back to passing no override at all, which is the behavior from before this file existed; the wake is never lost over model choice, and the command says plainly when main's model could not be applied instead of reporting a change that did not take effect.
-A pin naming a model Pi cannot hand back, because the model is unknown or has no configured credentials, is never silently downgraded onto main's model: the branch refuses to build and rejects the accepted wake to the watcher's captain-facing main path, exactly as any other unreachable branch does.
+
+### Unavailable models
+
+For ordinary Pi providers, an unpinned build passes no model override only when main's model is unknown or this home's stored credentials cannot run it in the isolated branch runtime.
+This preserves the behavior from before the file existed.
+Model choice never loses the wake.
+If main's model could not be applied, the command reports that failure instead of reporting a change that did not take effect.
+If a pin names a model Pi cannot return because it is unknown or has no configured credentials, the branch refuses to build.
+It sends the accepted wake back to the watcher's captain-facing main path, as any other unreachable branch does.
+It never silently falls back to main's model.
+
 Picking also releases the live branch so the next wake reopens this session's own branch conversation under the new model without waiting for a session replacement.
 
-The effort file holds one Pi thinking level followed by one newline, and the two pins are independent: a captain may pin a model, an effort, both, or neither.
-The effort step runs after the model step because the effective branch model decides which levels exist: its menu is Pi's own supported-level list, so a model that maps no extended levels simply does not offer them and a non-reasoning model offers only `off`.
+### Effort file format and available levels
+
+The effort file holds one Pi thinking level followed by one newline.
+Model and effort pins are independent: a captain may pin either, both, or neither.
+The effort step follows the model step because the effective branch model determines which levels exist.
+The menu uses Pi's own supported-level list.
+Models without extended levels do not offer them; a non-reasoning model offers only `off`.
+
 The picker keeps no effort catalog of its own; when main's model cannot be resolved, it first resolves the model recorded by the most recent branch conversation and uses Pi's supported levels for that effective model.
 If neither model can be resolved, the picker invents no levels and the command says that the branch's effective effort cannot be determined.
-An absent, unreadable, or unrecognized file means no effort pin, and the branch then follows main's own current effort, applied explicitly and live whenever main changes effort mid-session.
+
+### Applying and changing an effort pin

+An absent, unreadable, or unrecognized file means no effort pin.
+The branch then follows main's current effort, applied explicitly and live whenever main changes effort mid-session.
 A valid pin wins over main and remains unaffected by main's effort changes.
+
 Picking "Follow main" removes the file, and the command writes an effort pin at mode `0600` and replaces it atomically, exactly as it writes a model pin.
 The effort file's current state decides the branch effort on every branch build, on the same create-and-reopen contract as the model pin and for the same reason: a reopened branch conversation records the effort it last ran under, so only an explicit override keeps "Follow main" honest.
+
 Only when main's own effort cannot be read either does an unpinned build fall back to passing no effort override at all, which is the behavior from before this file existed.
-Pi owns the clamp, so a pinned level the branch's model cannot run becomes that model's nearest supported level rather than a refusal; the branch is never refused over effort, the captain's raw pick is kept so it applies again on a model that supports it, and the command reports the level the branch will really run at rather than the raw pin.
+
+### Unsupported effort levels
+
+Pi maps an unsupported pinned level to the branch model's nearest supported level.
+Effort never causes the branch to refuse a build.
+The captain's raw pick is kept so it applies again on a model that supports it, and the command reports the level the branch will actually use.
 An effort token Pi would not recognize at all is treated as no pin rather than passed to that clamp, which would otherwise collapse a typo into the model's lowest level.
 
+### Cancellation and inheritance
+
 Cancelling the model picker cancels the whole command and changes neither choice.
-Cancelling only the effort picker keeps the standing effort choice and still applies the model pick made in the same run, and the command's one closing message reports both choices as they will actually take effect.
+Cancelling only the effort picker keeps the standing effort choice and still applies the model pick from the same run.
+The command's closing message reports both choices as they will take effect.
+
 Both choices are local to each Firstmate home and are not part of secondmate inherited configuration, the same as the Calm preference; a secondmate home pins its own supervision model and effort with its own `/supervision-model`.
 
 ## Supervision host (config/supervision-host)
 
-The optional local, gitignored `config/supervision-host` opts this home into the supervision host, which runs the supervision branch's contract on a headless engine session beside a non-Pi primary; [docs/supervision-host.md](supervision-host.md) owns the design, its current scope, and the verified engines.
-Today a Claude, Cursor, OpenCode, omp, Grok, or Codex primary runs it, and only for the away posture: with the file present, that primary's arm owner runs the host in the watcher arm's place, the host handles wakes on the engine while the away-posture record `state/.afk-contract` exists, and `/afk` launches no away daemon on that home, while `/quiet` still does.

 The tracked `.tasks.toml` pins the default `tasks-axi` markdown backend to `data/backlog.md`, with `done_keep = 10` and an archive at `data/done-archive.md`.
 A home may instead select another tasks-axi adapter such as Beads through its own `.tasks.toml` or `TASKS_AXI_BACKEND`; firstmate still uses only tasks-axi verbs for routine backlog reads and mutations, and the adapter maps `start` and evidence-bearing `done` transitions to its native statuses and evidence fields.
+
+### Captain holds on Beads
+
 Captain-hold row creation is owned by [`bin/fm-captain-hold.sh`](../bin/fm-captain-hold.sh) `hold`: when no work item exists, it creates an ordinary backlog row (`--kind captain` metadata; Beads native type `task`) and then applies the captain hold.
 Captain rows have no Beads due semantics, so that create path waives a Beads `due.required` setting rather than passing a synthetic `--due`; `--until` remains the optional hold deferral.
+
 Do not register a Beads `types.custom` `captain` type for this: captain is a hold kind, and the fleet Beads `due.required` policy for ordinary work stays in the federated beads config.
-When the automatic transition gate applies, dispatch and completion are not separate operator actions: each moves its work item inside the same run that creates or removes the task's record, so the ordinary successful path cannot leave the backlog and live task set out of sync ([`bin/fm-backlog-transition-lib.sh`](../bin/fm-backlog-transition-lib.sh)).

 Under that gate, dispatch accepts only an unheld, unblocked Queued or In flight item in this home; a missing, Done, held, or dependency-blocked item is refused before any endpoint or local copy is created.
-[`bin/fm-tasks-axi.sh`](../bin/fm-tasks-axi.sh) refuses `add --start` and its `create --start` alias so neither spelling places a row In flight without dispatch artifacts, because such a row would have no task record, status file, or inbox and would count as live work nobody is doing; `tasks-axi start <id>` remains a documented direct transition the wrapper passes through.

 Completion refuses to report success until the item is closed, and session start reconciles this home's own books after an interrupted run.
+
 When a spawn is interrupted after launch delivery began, its exit path re-reads the paired task record and the backlog row under the same per-task lock as the commit, repairs a row the commit believed it had moved, and reports only what was verified or honestly attempted, never intent phrased as outcome ([`bin/fm-spawn.sh`](../bin/fm-spawn.sh); [`tests/fm-backlog-atomicity.test.sh`](../tests/fm-backlog-atomicity.test.sh)).
+
+### Which backlog receives a transition
+
 Automatic transitions run from the configured data directory's parent, letting that home's effective tasks-axi configuration address its selected adapter while keeping relative scout-report links rooted there.
 A markdown backlog is additionally addressed by an explicit `--file` at `<data>/backlog.md`, so the change lands in the home that owns the task regardless of the caller's working directory.
+
 Any other configured adapter is addressed by that root alone, because `--file` would override the adapter's own workspace path.
-The gate does not apply to persistent secondmates, manual-backend homes, or markdown homes without a backlog file, preserving their existing persistent-agent, manual, or ad-hoc lifecycle behavior while configured non-markdown adapters remain active without that file.
+
+### Exemptions and refusal conditions
+
+The gate does not apply to persistent secondmates, manual-backend homes, or markdown homes without a backlog file.
+Those retain their existing persistent-agent, manual, or ad-hoc lifecycle behavior.
+Configured non-markdown adapters remain active without that file.
 Migrated-hold resolution on a beads home reads its graph path, binary, and prefix from the root `.tasks.toml` `[beads]` section only, and refuses (rc=2) when the beads backend is selected elsewhere (a `TASKS_AXI_BACKEND` override or user-level config) with no root-level `[beads]` section.
+
 On an automatic-backend home, missing or incompatible `tasks-axi`, an unresolvable configured data directory, or one containing a control byte fails lifecycle work before mutation.
 An unreadable backend configuration can refuse lifecycle work before the no-backlog exemption applies; repair the configuration named in the diagnostic ([backend resolution contract](../bin/fm-tasks-axi-lib.sh)).
+
+### Handoffs between homes
+
 Secondmate handoffs bypass that routine-backend choice: `fm-backlog-handoff.sh` keeps only its own fleet-level validation and delegates the item move to `tasks-axi mv`; its [script header](../bin/fm-backlog-handoff.sh) owns route-specific wake outcomes and remote outbox release.
 It moves in-scope `## Queued` items only and refuses `## In flight` and historical `## Done` records, which stay with their home for pruning or archiving.
+
 Handoff item bodies must use at least two leading spaces, and the helper refuses a selected item with a single-space or tab-indented continuation rather than risk orphaning it.
 Because bootstrap requires `tasks-axi` on `PATH` on every profile, that delegation works fleet-wide, and the `config/backlog-backend=manual` knob governs firstmate's own hand-editing of its backlog, not this validated helper.
+
+### Required tools and manual mode
+
 Compatible means the installed build passes the shared version and feature probe owned by [`bin/fm-tasks-axi-lib.sh`](../bin/fm-tasks-axi-lib.sh), including the atomic multi-ID move required by handoff delegation.
 Bootstrap requires compatible `tasks-axi` on every profile; see "Toolchain" below for missing-tool reporting and silent default-backend behavior.
+
 Set the local, gitignored `config/backlog-backend` file to `manual` to force manual backlog editing and suppress the verbose `BOOTSTRAP_INFO: tasks-axi available` fact, not missing-tool reporting.
 A `manual` home owns its backlog file outright: the lifecycle transitions above are skipped there, dispatch and completion never fail over the file's contents, and a completed teardown prints the hand edit that is owed instead.
+
 Absent or `tasks-axi` selects the tasks-axi path.
 On the default markdown adapter, tasks-axi and manual edits produce the same `## In flight`, `## Queued`, and `## Done` sections.
 
+### Using a separate operational home
+
 The tracked `.tasks.toml` paths resolve against the directory tasks-axi runs in, not `FM_HOME`, so a bare `tasks-axi` run from the code root addresses the code root's `data/` whenever the home lives elsewhere.
-tasks-axi writes by renaming a temp file over its target, which replaces a symlink with a regular file, so linking the code-root copy into the home forks the queue on the first such write rather than keeping the two in step.
-Every routine firstmate backlog command therefore runs through [`bin/fm-tasks-axi.sh`](../bin/fm-tasks-axi.sh), which addresses this home's backlog and archive from any working directory exactly as lifecycle transitions do, and bootstrap reports a code-root `data/backlog.md` or `data/done-archive.md` that is not this home's own file as a `BACKLOG_RECONCILE: code-root ...` line even in a read-only session.

 ## Runtime backend (config/backend / FM_BACKEND)
 
 For spawn-capable adapters, the runtime session-provider backend controls where task windows/endpoints are created, captured, sent to, watched, and killed.
-`tmux` is the verified reference backend (see [`docs/tmux-backend.md`](tmux-backend.md)); `herdr` has its own required CI lane (see [`docs/herdr-backend.md`](herdr-backend.md)); `zellij`, `orca`, and `cmux` remain experimental spawn backends with no dedicated real-backend CI lane (see [`docs/zellij-backend.md`](zellij-backend.md), [`docs/orca-backend.md`](orca-backend.md), and [`docs/cmux-backend.md`](cmux-backend.md)).
+
+| Runtime backend | Verification status | Reference |
+| --- | --- | --- |
+| `tmux` | Verified reference backend | [`docs/tmux-backend.md`](tmux-backend.md) |
+| `herdr` | Has its own required CI lane | [`docs/herdr-backend.md`](herdr-backend.md) |
+| `zellij` | Experimental; no dedicated real-backend CI lane | [`docs/zellij-backend.md`](zellij-backend.md) |
+| `orca` | Experimental; no dedicated real-backend CI lane | [`docs/orca-backend.md`](orca-backend.md) |
+| `cmux` | Experimental; no dedicated real-backend CI lane | [`docs/cmux-backend.md`](cmux-backend.md) |
+
 Treehouse remains the worktree provider for tmux, herdr, zellij, and cmux, since herdr, zellij, and cmux are session providers only; Orca provides both the task worktree and terminal endpoint.
-New spawns choose the backend in this order: an explicit `--backend` flag that current authority for that exact task alone has authorized (a present captain instruction or the task's own accepted brief; never later-task precedent by analogy), then `FM_BACKEND`, then the first non-empty line of local gitignored `config/backend`, then runtime auto-detection from `$TMUX`, `HERDR_ENV=1`, or cmux runtime signals, then default `tmux`.
+
+### Backend selection order
+
+New spawns choose the backend in this order:
+
+1. An explicit `--backend` flag authorized for that exact task by a present captain instruction or the task's own accepted brief.
+   A later task cannot inherit that authority by analogy.
+2. `FM_BACKEND`.
+3. The first non-empty line of local, gitignored `config/backend`.
+4. Runtime auto-detection from `$TMUX`, `HERDR_ENV=1`, or cmux runtime signals.
+5. Default `tmux`.
+
 If more than one runtime marker is present, detection resolves innermost-first: `$TMUX` is checked before `HERDR_ENV=1`, which is checked before cmux's primary `CMUX_WORKSPACE_ID` marker and its documented fallback signals - tmux or herdr started from inside a cmux terminal is the innermost, currently-executing layer, while cmux itself (a terminal application, not a nestable multiplexer) is always checked last.
 See [`docs/cmux-backend.md`](cmux-backend.md#runtime-detection) for why cmux can be selected when `CMUX_WORKSPACE_ID` is absent.
+
 Auto-detected Herdr stays silent like tmux, while auto-detected cmux prints a stderr notice naming `config/backend` and `--backend tmux` because cmux remains experimental.
 Zellij and Orca are never auto-detected; select them by putting the name in a local `config/backend` file, by exporting `FM_BACKEND=<name>`, or by telling the first mate in chat.
+
+### Accepted backends and secondmate limits
+
 Any value other than `tmux`, `herdr`, `zellij`, `orca`, or `cmux` is rejected until another adapter is implemented and verified.
 `fm-spawn.sh` accepts `tmux`, `herdr`, `zellij`, `orca`, and `cmux` for ship and scout tasks; `backend=orca` and `backend=cmux` both still refuse `--secondmate` until secondmate launch semantics are designed for each.
+
 `codex-app` is not an accepted runtime backend yet; [`docs/codex-app-backend.md`](codex-app-backend.md) owns the Codex App boundary.
+
+### Liveness classification
+
 The session-start secondmate liveness sweep and the watcher's secondmate liveness tick use the recovery-grade `fm_backend_agent_state` classifier where verified.
 The comment above that function in `bin/fm-backend.sh` is the single owner of its detailed state contract and recovery authorization.
+
 The compatibility helper `fm_backend_agent_alive` continues to collapse those detailed results to `alive`, `dead`, or `unknown` for older callers.
-A herdr spawn additionally version-gates against the installed `herdr` binary's protocol and requires `jq`, refusing loudly on an incompatible or missing installation.
-A zellij spawn additionally version-gates against the installed `zellij` binary's version and requires `jq`, refusing loudly when either is missing or the version is older than 0.44.
-A cmux spawn additionally version-gates against the installed `cmux` binary's version, requires `jq`, and requires the control socket to be reachable and accessible (see [`docs/cmux-backend.md`](cmux-backend.md) "Setup" for the one-time socket-access configuration this needs; Automation mode is the recommended socket control mode, with Password mode supported via `config/cmux-socket-password`), refusing loudly and non-retryably on a `cmuxOnly`/unauthenticated socket.

+
 A backend spawn refusal from a missing dependency, version gate, or unauthenticated socket is terminal for that selected backend; firstmate surfaces it as a blocker instead of silently retrying another backend.

+### Task metadata
+
 Task meta records `backend=` only for a non-default backend; an absent `backend=` means `tmux`, preserving existing default-path meta files.
-Every new task records `endpoint_task_id=` as the cleanup binding between the metadata filename and its opaque runtime endpoint.
-A herdr task additionally records `herdr_session=`, `herdr_workspace_id=`, `herdr_tab_id=`, and `herdr_pane_id=`.
-A zellij task additionally records `zellij_session=`, `zellij_tab_id=`, and `zellij_pane_id=`.
-An Orca task additionally records `orca_worktree_id=` and `terminal=`, with `window=fm-<id>` kept as the shared firstmate alias.
-A cmux task additionally records `cmux_workspace_id=` and `cmux_surface_id=`.

+### Task selectors
+
 Task selectors for `fm-peek.sh`, `fm-send.sh`, and `fm-crew-state.sh` resolve centrally through `fm_backend_resolve_selector`.
 A selector containing `:` is passed through as an explicit backend endpoint escape hatch.
+
 Otherwise an exact task id matching `state/<id>.meta` wins before the legacy `fm-<id>` label fallback, so task ids that themselves start with `fm-` route to their own metadata instead of being stripped.
 A metadata-routed selector returns the recorded backend target (`terminal=` for Orca, otherwise `window=`), and matching explicit targets can still recover the recorded backend when metadata contains the same endpoint.
+
 Only metadata-routed task selectors carry secondmate-marker and Codex-harness context; explicit endpoint escape hatches do not.

+### Teardown identity checks
+
 `fm-teardown.sh <id>` takes a task id directly and validates the complete metadata-only endpoint identity before any runtime dispatch or cleanup mutation.
 Missing, empty, duplicate, malformed, backend-inconsistent, or task-mismatched endpoint records are preserved and refused.
+
 Legacy tmux metadata remains cleanup-compatible when its exact window name is `fm-<id>`; opaque non-tmux endpoints require their recorded `endpoint_task_id=` binding.
+
+### Herdr homes and presentation
+
 `FM_HOME` determines Herdr's home label: the primary home uses `firstmate`, and a secondmate home marked by `.fm-secondmate-home` uses `2ndmate-<secondmate-id>`.
 [`herdr-backend.md`](herdr-backend.md#watching-and-task-containers) owns launcher-bound workspace placement, the label-only fallback, collision handling, and recovery behavior.
+
 The local `config/herdr-presentation-spaces` file instead opts a home out of, or explicitly in to, Herdr's default-on disposable single-task visual projection; [Presentation spaces](herdr-backend.md#presentation-spaces) owns its accepted values, default, Herdr version floor, migration, behavior, safety limits, recovery contract, and narrow locked session-start cleanup of exact restored idle-shell children.
 The setting is inherited into secondmate homes under the primary-authoritative contract owned by [`secondmate-provisioning`](../.agents/skills/secondmate-provisioning/SKILL.md).
+
 For normal herdr operations, `HERDR_SESSION` selects the named session, but destructive test cleanup must not rely on `HERDR_SESSION` alone.
 Use the explicit guarded cleanup path described in [`docs/herdr-backend.md`](herdr-backend.md) instead of `herdr server stop`.
+
+### Zellij sessions
+
 For normal zellij operations, `FM_ZELLIJ_SESSION` selects the named session and defaults to `firstmate`.
 Zellij has no per-home workspace split: primary and secondmate tasks share that one session, and visible tab titles are scoped by the active `FM_HOME` readable label plus a short hash of the resolved `FM_ROOT` path as `fm-<home-label>-<id>`.
+
 Use the guarded cleanup path described in [`docs/zellij-backend.md`](zellij-backend.md) instead of `kill-all-sessions` or `delete-all-sessions`.

 cmux has no session layer at all - one workspace per task, in whatever cmux window is open - and its socket password (when configured) is read from local, gitignored `config/cmux-socket-password` under the effective config directory, never committed.
 The caller-facing label remains `fm-<id>`, but the actual cmux workspace title is scoped by the active `FM_HOME` readable label plus a short hash of the resolved `FM_ROOT` path as `fm-<home-label>-<id>`.

 ## Away-mode wedge alarm channels (config/wedge-alarm)
 
 When away-mode injection wedges past `FM_MAX_DEFER_SECS`, the sub-supervisor raises a loud, rate-limited alarm.
 Beyond the durable `state/.subsuper-inject-wedged` marker and the tmux status-line flash, it attempts a configured backend-independent active alert that can reach the captain even when every pane and its backend status-line is unreadable.
+
+### Channels and overrides
+
 `config/wedge-alarm` (local, gitignored) lists channel directives, one per non-empty, non-comment line; every listed non-`off` channel fires, best-effort.
 `FM_WEDGE_ALARM_CHANNEL` overrides the file with a single directive.
+
 Directives are `off` (a position-independent kill switch that disables every active alert), `auto`/`default`, `osascript` (macOS Notification Center banner), `herdr` (herdr UI notification), and `command:<cmd>` (run `<cmd>` via `sh -c`, summary on `$1` and stdin).
 An absent file means `auto`, i.e. default-on on macOS: the alarm exists precisely so a wedged away-mode primary is never silent, and it fires at most once per max-defer window after a genuine wedge.
+
 A missing or failing channel logs and falls through to the next, never crashing the daemon.
 See [`wedge-alarm.md`](wedge-alarm.md) for the current channel reference, [`verification/supervision.md`](verification/supervision.md#wedge-alarm-channels) for active evidence, and [`examples/wedge-alarm`](examples/wedge-alarm) for a copyable config.
 
 ## Trace context propagation (config/trace-context / FM_TRACE_CONTEXT)
 
 The optional local, gitignored `config/trace-context` presence flag enables default-off native W3C trace-context propagation.
+
+### Precedence and session boundary
+
 `FM_TRACE_CONTEXT` overrides the file: `1`/`on`/`true`/`yes` enables, any other non-empty value disables, and unset or empty defers to the file.
 Each locked home session resolves those inputs once, and all spawns from that home use the frozen decision until a new session starts.
+
+### Secondmate propagation
+
 When launching a Secondmate, the primary copies the presence flag into its home and passes the primary session's frozen decision as a non-empty `FM_TRACE_CONTEXT=on|off` override for the Secondmate's own session start.
 A Secondmate on a remote route is covered the same way: the primary resolves and records that task's carrier, and the configured host exports it and receives the same enablement snapshot.
+
 The presence flag is session-scoped enablement, so it transfers at launch and is left unchanged by live convergence into a running home.
 See [`trace-context.md`](trace-context.md) for carrier semantics, supported routes, the manual fleet-restart requirement, the session boundary, and safety limits; `bin/fm-trace-context-lib.sh`'s header owns the exact mechanics, and [`verification/trace-context.md`](verification/trace-context.md) records repeatable evidence.

+
 It stays opt-in because the other two proofs read a verdict the harness itself vouches for while this one infers execution from rendered bytes; with the flag absent triage behaves exactly as it did before.

 The bound is required rather than cosmetic because churn and pane staleness read the same pane.

 ## Parked-gate wait deferral (config/wedge-defer-parked-gate)
 
 The optional local, gitignored `config/wedge-defer-parked-gate` presence flag opts this home into a default-off second form of wait evidence in the watcher's wedge timer.
+
+### When a waiting gate defers an alarm
+
 With it present, a provably-working pane about to escalate is also deferred to the `FM_PAUSE_RESURFACE_SECS` recheck cadence when its crew's own current state is a validation gate whose answer is owed to the supervisor and whose decision for that run is still open, and the recheck names the supervisor and the action that clears the lane instead of reporting a suspected wedge.
 It stays opt-in because the other evidence is the worker's own declaration about its own silence, while this is derived from a pipeline's gate state, so which lanes give up the escalation ladder for it is a home's choice.
+
 With the flag absent the wedge timer spends no fold or current-state read for it, writes no record, and keeps the unchanged escalation schedule, reasons, and `demand-deep-inspection` wording.
 The flag is a home-local supervision-noise preference and is not inherited by secondmate homes, which supervise their own crew and own that trade separately.

 ## Gate defaults (.no-mistakes.yaml)
 
 The tracked `.no-mistakes.yaml` sets `test.evidence.store_in_repo: true` and pins `commands.lint` to `bin/fm-lint.sh`, the same owner CI invokes.
 Storing evidence in the repo publishes each run's test artifacts to the orphan `no-mistakes/evidence` branch and links them from the PR body, instead of keeping them on local disk under the no-mistakes home.
+
 That branch shares no history with code branches, so evidence never enters a pushed feature branch or the default branch; the worktree's `.no-mistakes/` stays local and CI rejects tracked entries under that path.
 The [`firstmate-coding-guidelines` skill](../.agents/skills/firstmate-coding-guidelines/SKILL.md#no-mistakes-test-configuration) owns why `commands.test` stays absent and targeted validation belongs to the evidence path.
+
 `commands.test` executes code, so no-mistakes honors it only from the default-branch copy of `.no-mistakes.yaml`; a pushed branch cannot change what the gate runs.

 ## Captain Preferences (data/captain.md / data/captain-shared.md)

 ## Startup memory budget (config/startup-memory-budget)
 
 `config/startup-memory-budget` is the primary-authoritative per-home allowance for the startup prompt-memory surface: `data/captain.md`, `data/captain-shared.md`, and `data/learnings.md` together.
 The locked mutable bootstrap path materializes its visible default of `7500` estimated tokens in a primary home when the file is absent.
+
+### Set and validate the budget
+
 To select another allowance, replace the primary home's file with one valid positive value in the exact format below; the next locked bootstrap convergence or `bin/fm-config-push.sh` propagates it to registered secondmates.
 A secondmate does not create an independent default and instead receives the primary value through the inherited-local-material contract in [`secondmate-provisioning`](../.agents/skills/secondmate-provisioning/SKILL.md).
+
 The file must be one positive base-10 integer followed by exactly one newline in a regular, single-linked file beneath a non-symlinked `config/` directory.
 Malformed, multi-line, symlinked, hardlinked, special, or otherwise unsafe values are rejected rather than treated as a default.
+
+### Accounting and curation
+
 Use `bin/fm-startup-memory-budget.sh read` to validate and print the effective value, or `bin/fm-startup-memory-budget.sh report` to account for the three files.
 The stable local estimate is `ceil(UTF-8 bytes / 3)` per file, a conservative portable approximation rather than a provider-exact tokenizer.
+
 An inherited `data/captain-shared.md` counts in a secondmate's total but remains primary-owned and read-only there.
 The internal [`/stow` skill](../.agents/skills/stow/SKILL.md) owns curation and its automatic secondmate cascade, which accounts every home against this same per-home allowance separately rather than against a fleet total.
+
 The helper's header owns exact parsing, publication, and report output mechanics.
 
 ## Stow pass horizon (config/stow-pass-horizon)
 
 `config/stow-pass-horizon` is an optional local, gitignored presence flag that opts this home in to the pass-count decay horizon in the internal [`/stow` skill](../.agents/skills/stow/SKILL.md).
 Without it a `/stow` pass decays memory entries on their wall-clock horizons alone - 30 days for `aging`, 7 days for `perishable` - which is the default and unchanged behavior.
+
 With it, an entry is also stale after 10 passes (`aging`) or 3 passes (`perishable`) that evaluated it without reinforcing it, whichever horizon it reaches first.
 Opt in for a home that stows often enough that entries never sit unreinforced for a wall-clock horizon, so memory only grows against the startup-memory budget above; a home that stows rarely already exceeds its date horizon on a single pass and gains nothing.
+
 The flag is per home and is not inherited by secondmate homes, because stow cadence is a property of the home doing the stowing.
 Only the file's presence is read, so its contents are ignored; remove it to return to the default contract on the next pass.
+
 The skill text owns the marker spelling, the tick order, and the reinforcement rule.
 
 ## Secondmate routes (data/secondmates.md)
 
 Persistent secondmate routes live locally in `data/secondmates.md`.
 The concise single-line route contract is owned by the [`secondmate-provisioning` skill](../.agents/skills/secondmate-provisioning/SKILL.md#routing-table), including the parser-compatible fields, one-sentence summary requirement, `home:` pointer to the seeded charter, and limit on extra registry prose.
+
+### Remote routes and validation
+
 A remote route adds `host:` and `root:` before the existing fields and places the whole secondmate home on that SSH host; it does not make ordinary workers remotely placeable.
 [`remote-secondmates.md`](remote-secondmates.md) owns current remote setup, operation, and safety behavior.
+
 Use `fm-home-seed.sh validate` to check the complete operational registry contract documented by the command itself.
 The main first mate routes by reading those scopes with judgment; the project list is provisioning data, not exclusive ownership.
+
+### Provision a local home
+
 Use `fm-home-seed.sh <id> - {<project>...|--no-projects}` to lease a fresh local firstmate worktree for the secondmate home.
 For remote provisioning, including supplied project origins, follow [Remote second mates](remote-secondmates.md#provision-a-route).
+
 Use the deliberate `--no-projects` signal only for a firstmate-repo domain that needs no separate project clones.
 It cannot be combined with a project list, and omitting both still fails loudly.
+
 A project-less seed requires no existing project clones or `data/projects.md` entries in the home, so it refuses a populated-home conversion without changing that home.
 A preexisting project-bearing charter is also refused until it is re-scaffolded with `--no-projects` or removed.
+
 The lease is held under the secondmate id until explicit retirement or seed rollback returns it, so normal restarts do not free or recycle the home.
 Teardown of a leased home fails closed if `treehouse return` cannot release the lease; plain-clone homes with no treehouse pool slot are removed directly.
+
+### Project modes and backlog handoff
+
 Secondmate routes cover `no-mistakes` and `direct-PR` projects; `local-only` projects remain main-firstmate work.
 For `no-mistakes` projects, seeding initializes only projects newly cloned into a secondmate home and refuses to mutate a preexisting clone that is not already initialized.
+
 After creating a secondmate, move existing main-backlog queued items that you have judged in-scope with `fm-backlog-handoff.sh <secondmate-id> <item-key>...`; it refuses In flight, Done, or non-secondmate homes, and its [script header](../bin/fm-backlog-handoff.sh) owns route-specific wake outcomes and retries.
 Set `FM_SECONDMATE_CHARTER` to seed from inline charter text when no filled charter brief exists; set `FM_SECONDMATE_SCOPE` when the routing scope should differ from the charter text.
+
 The seeded home's `data/charter.md` owns the standard secondmate lifecycle and escalation contract; the route file points to it through the existing `home:` field instead of adding another pointer.
+
+### Identity markers and upgrades
+
 Each seed writes an `.fm-secondmate-home` identity marker at the home root, alongside a durable `.fm-secondmate-parent` record of the home's route to its parent (see "Provision a route" in [`docs/remote-secondmates.md`](remote-secondmates.md)).
 The tracked root `.gitignore` ignores both markers, so validation can read them without making a freshly seeded home appear dirty to porcelain-based safety checks.
+
 This does not relax protection for any other untracked file.
 An existing linked-worktree home that predates this rule advances through its marker-only state during its next bootstrap or spawn local sync, after which Git ignores the marker normally.
-A local standalone-clone home cannot receive a primary-local commit through that no-fetch sync, so it receives the rule through `/updatefirstmate`'s origin refresh instead.

-## FM_HOME
 
-`FM_HOME` selects the operational home for one firstmate instance.
-When it is unset, most scripts use the repo root as the home; when it is set, scripts still run from this repo's `bin/`, but `state/`, `data/`, `config/`, and `projects/` come from `$FM_HOME`.
-`FM_ROOT_OVERRIDE` overrides the firstmate repo root used by scripts, including the primary checkout watched by the worktree-tangle guard.
-When `FM_HOME` is unset, it also behaves as the old whole-root override.
-`bin/fm-send.sh` is intentionally stricter than that general fallback: it requires `FM_HOME` to be set before resolving a target, so operator steers cannot silently resolve against the wrong home.
-`FM_STATE_OVERRIDE`, `FM_DATA_OVERRIDE`, `FM_PROJECTS_OVERRIDE`, and `FM_CONFIG_OVERRIDE` override individual operational directories for tests and specialized harness setup.
-Before `fm-brief.sh`, `fm-spawn.sh`, or `fm-afk-launch.sh` persists a path or passes it to another process, it resolves each applicable relative `FM_HOME`, `FM_STATE_OVERRIDE`, or `FM_DATA_OVERRIDE` directory against the caller's working directory, preserves accepted absolute spellings unchanged, and rejects an unresolvable relative directory with the offending variable named.
-`fm-spawn.sh` additionally rejects control bytes in those raw directory inputs before shell or filesystem normalization can change which path the backlog gate checks.
-Lifecycle access to a backlog, task record, or pending-close record must resolve within its configured data or state root, and a final-component symlink is refused even when its target remains within that root.
-Bootstrap applies the same relative `FM_HOME` resolution only when embedding that home in the generated Relay poll shim; other transient consumers retain their existing shell-relative behavior.
-For the herdr backend, `FM_HOME` also determines the workspace label used by the adapter.
-For the zellij backend, `FM_HOME` does not split containers, but it determines the readable home prefix embedded in visible tab titles; use `FM_ZELLIJ_SESSION` when a separate zellij session is needed.
-The full zellij home label also includes a short hash of the resolved `FM_ROOT` path.
-For the cmux backend, `FM_CONFIG_OVERRIDE` overrides where `config/cmux-socket-password` is read from, while `FM_HOME` determines the default config path and readable home prefix embedded in workspace titles.
-The full cmux home label also includes a short hash of the resolved `FM_ROOT` path, and there is no per-home container split.

 ## Harness support
 
 claude, codex, opencode, pi, pi-signed, grok, kimi, cursor, and omp are empirically verified for crewmate and secondmate launches; gemini is verified for crewmate and scout launches only, and [README requirements](../README.md#requirements) own the set supported for the primary session.
+
+### Harness restrictions and credentials
+
 `fm-spawn.sh` refuses kimi on cmux and Orca at preflight, because answering Kimi's folder-trust dialog needs a verified viewport-only capture those backends lack; [its adapter reference](../.agents/skills/harness-adapters/references/harness/kimi.md#readiness-gated-start) owns the trust-dialog handling.
 A cursor secondmate or primary runs the tracked project-scope `.cursor/hooks.json` in its own home and must be launched with `--trust`, or no project hook loads; [`docs/supervision-protocols/cursor.md`](supervision-protocols/cursor.md) owns its supervision protocol.
+
 Cursor typed-submit confirmation is verified on tmux and Herdr only.
 On Zellij, cmux, and Orca a typed-plane Cursor send (a harness-native invocation or an explicit backend target; ordinary text steers ride the durable inbox and exit 0 at enqueue) lands, but `fm-send` reports delivery unconfirmed and exits non-zero because their shared submit core does not consult the busy footer; [runtime backend verification](verification/runtime-backends.md#cursor-agent-cli) owns the evidence and transcript-state boundary.
+
 muse is verified for crewmate and scout launches ONLY, and `fm-spawn.sh` refuses it for a secondmate, because muse ships no usable hook surface for a primary session's turn-end supervision; [`docs/verification/muse.md`](verification/muse.md) owns that evidence.
 muse also needs a worker-reachable credential before spawning, and the portable fleet path is the `<config>/muse/auth.json` credential stored by `muse login`, because a caller-only `META_API_KEY` does not cross a long-lived backend daemon.
+
 gemini is likewise refused for secondmates because it has no primary supervision protocol; [its adapter reference](../.agents/skills/harness-adapters/references/harness/gemini.md) owns the credential precondition, canonical-launch wiring, and raw-launch limitations.
 rovo is likewise verified for crewmate and scout launches ONLY, refused for a secondmate for the same reason - no turn-end hook and no primary supervision protocol; [`docs/verification/rovo.md`](verification/rovo.md) owns that evidence, including the OAuth token's silent background refresh from a stored refresh token and both tmux and herdr pane liveness (herdr placement is verified live, with a Herdr-side agent-detection gap left open for recovery classification).
+
 agy is likewise verified for crewmate and scout launches ONLY, refused for a secondmate for the same reason - no hook surface and no primary supervision protocol; [`docs/verification/agy.md`](verification/agy.md) owns that evidence, including the spawn-time worktree trust pre-registration through `bin/fm-agy-trust.sh` and Herdr's native agy pane recognition.
 devin is verified for crewmate and scout launches only; a secondmate is refused because Devin has no verified primary supervision protocol.
+
 Its private worker config disables Claude Code imports (including the captain's hooks) and Devin commit attribution without editing user or project config; [`fm-devin-config.sh`](../bin/fm-devin-config.sh) owns these enforced settings and [Devin verification](verification/devin.md) owns the live evidence and observed model availability.
+
+### Verification and primary supervision
+
 New harnesses get verified through a supervised trial task before joining the set.
 The verified adapter evidence - each harness's busy-state source, interrupt and exit behavior, skill-invocation syntax, and per-harness quirks - lives in the skill tree rooted at [`.agents/skills/harness-adapters/SKILL.md`](../.agents/skills/harness-adapters/SKILL.md).
+
 The executable interrupt and exit mechanics live in [`bin/fm-control-lib.sh`](../bin/fm-control-lib.sh), and [`docs/agent-control.md`](agent-control.md) owns their lifecycle-control architecture.
 Launch mechanics, including the verified command templates, live in [`bin/fm-spawn.sh`](../bin/fm-spawn.sh).
+
 Pi-family launches adapt the regular-TUI safeguard to the installed CLI's capabilities; [`fm-spawn.sh --help`](../bin/fm-spawn.sh) owns the exact version-safe launch mechanics.
 Enabled primary-session turn-end guard integrations are tracked as repo-level hook files and documented in [`docs/turnend-guard.md`](turnend-guard.md).
+
 Kimi remains outside the primary turn-end guard integrations; [`docs/turnend-guard.md`](turnend-guard.md#compatibility-limits) owns its separate captain-approved crew wake hook.
 Primary-session watcher wake protocols are rendered at session start by [`bin/fm-supervision-instructions.sh`](../bin/fm-supervision-instructions.sh) from [`docs/supervision-protocols/`](supervision-protocols/).
+
 Claude's Stop `asyncRewake` hook owns tokenless re-arm cycles, Cursor's stop hook parks on the watcher, Grok uses background-notify cycles, Codex uses bounded foreground checkpoints, Pi and pi-signed use the same two tracked primary extensions, omp uses its own two tracked `.omp/extensions/` files with a blocking `session_stop` turn-end hook, and OpenCode uses its TUI plugin.
+
+### Choose the worker harness
+
 `config/crew-harness` is a local, gitignored file containing one adapter name for crewmate and scout launches.
 When pi-signed is selected, Firstmate preserves `FM_PI_HARNESS=pi-signed` and refuses the launch if the selected executable is unavailable rather than falling back to pi; [`fm-spawn.sh --help`](../bin/fm-spawn.sh) owns executable resolution and launch mechanics.
+
 Plain Pi launches set `FM_PI_HARNESS=pi`, so a signed primary's environment cannot relabel a plain Pi worker.
 When it is absent or contains `default`, crewmates mirror the firstmate's own harness.
+
+### Choose the secondmate harness
+
 `config/secondmate-harness` is a separate local, gitignored file containing the adapter the primary uses to launch secondmate agents, optionally followed by model and effort tokens on the same line.
 The first non-empty, non-comment line is parsed as `<harness> [<model>] [<effort>]`.
+
 A bare `<harness>` preserves the previous behavior: harness only, with no model or effort launch flag.
 When the harness token is absent or `default`, secondmate launch falls back through `config/crew-harness` and then the primary's own harness, and no model or effort is read from that file.
+
 `fm-harness.sh secondmate-model` and `fm-harness.sh secondmate-effort` expose only the optional tokens from `config/secondmate-harness`; `config/crew-harness` remains a bare adapter-name file.
 Changing this pin affects the next secondmate spawn or control-plane relaunch; the relaunch profile rules are owned by [`docs/agent-control.md`](agent-control.md#transactional-relaunch).
+
+### Per-launch overrides and inherited defaults
+
 An explicit harness argument to `fm-spawn.sh` still overrides either config file for that spawn only.
 An explicit `--model` or `--effort` overrides the matching token from `config/secondmate-harness`; for a local route, an explicit harness or raw launch command starts with clean model and effort defaults unless those flags are also passed.
+
 Remote secondmate routes accept verified harness adapters only and reject raw launch commands.
 When `config/crew-dispatch.json` exists, crewmate and scout spawns require an explicit resolved harness instead of automatically falling back to `config/crew-harness`.
+
 The inherited-local-material contract is owned by [`secondmate-provisioning`](../.agents/skills/secondmate-provisioning/SKILL.md); its harness-relevant consequence is that a secondmate's own crewmates use the primary's dispatch profiles and static harness value.
 Those inherited values are defaults and rules only; `fm-spawn` still permits a consciously chosen explicit runtime outside the config.
+
 `config/secondmate-harness` is not inherited because secondmates do not launch secondmates.
+
+### Installed hooks and launch details
+
 For grok, `fm-spawn.sh` installs one firstmate-owned global turn-end hook under `$GROK_HOME/hooks/`, or `~/.grok/hooks/` when `GROK_HOME` is unset, and drops a per-task `.fm-grok-turnend` pointer in the worktree, with teardown removing the task token and pointer.
 For Kimi crews, `fm-spawn.sh` runs `fm-kimi-turnend-hook.sh install`, drops a per-task `.fm-kimi-turnend` pointer in the worktree, and records the matching private registry token for teardown.
+
 Kimi continues to use the captain's normal Kimi home, including the existing config, skills, and memory; Firstmate does not create an isolated Kimi home.
 The Kimi installer requires an existing regular non-symlink `~/.kimi-code/config.toml`, `python3` with `tomllib`, and `jq`; it validates but never serializes the captain's TOML and refuses before writing when the config is missing, malformed, or surprising or when either tool requirement is unavailable.
+
 Its `remove` action excises only the marker-delimited Firstmate region and removes Firstmate's hook files.
 For Pi and pi-signed secondmate launches, `fm-spawn.sh` starts the selected executable with `-e` pointed at the secondmate home's own tracked `.pi/extensions/fm-primary-pi-watch.ts` and `.pi/extensions/fm-primary-turnend-guard.ts`, both already present from the secondmate home's git worktree.
+
 For omp secondmate launches, `fm-spawn.sh` passes no `-e` at all: omp auto-discovers the home's tracked `.omp/extensions/` with no trust gate, and naming a discovered file with `-e` as well loads it twice; every omp launch instead carries the tracked `.omp/fm-worker-overlay.yml` posture overlay through `--config`, which [`fm-spawn.sh --help`](../bin/fm-spawn.sh) owns.
 
 ## Claude permission mode (config/claude-permission-mode)

 The token is the file's whitespace-trimmed content.
-`bypass` keeps today's launch, `claude --dangerously-skip-permissions`, and is also the default when the file is absent, so an unconfigured home launches byte-for-byte as before.
-`auto` replaces that flag with `--permission-mode auto`, Claude Code's classifier-reviewed permission mode, for a captain who refuses to run workers in bypass mode; every other part of the Claude launch, including its environment prefix, inline settings, model, and effort flags, is unchanged.
-Any other value, or an unreadable file, refuses every spawn from that home, whichever harness it would launch, before any endpoint, worktree, or task record exists, and names the accepted values; Firstmate never falls back to a permission posture the captain did not choose.

+
+### When changes apply and inheritance
+
 `bin/fm-spawn.sh` reads the file on every spawn and relaunch, so a change takes effect at the next launch without a restart.
 The file is a captain-wide safety preference, so it is inherited into secondmate homes under the [`secondmate-provisioning`](../.agents/skills/secondmate-provisioning/SKILL.md) inherited-local-material contract; a secondmate's own Claude crewmates then launch on the same posture.
+
 The [Claude adapter reference](../.agents/skills/harness-adapters/references/harness/claude.md) records the verified shape of both launches and which once-per-machine dialog each one can meet.
 
 ## Worker account pin (config/claude-account, config/pi-account)
 
 A home that mixes accounts for one runner, such as a work login and a personal one, can pin the account its own Claude and Pi workers launch on.
 The pin is opt-in: with neither file, every launch is unchanged, and Claude workers keep receiving firstmate's own `CLAUDE_CONFIG_DIR` when it is set.
+
 Both files are local and gitignored.

+### File format and provider selection
+
 `config/claude-account` holds one line: `ordinary`, or the absolute path of an existing Claude config directory.
 `config/pi-account` holds that same root on line 1 and, on line 2, the providers this home may spend, separated by spaces, for example `openai-codex anthropic`.
+
 A final newline is optional; any other line, a relative path, or a control character such as a CR refuses.
 For Claude, `ordinary` unsets `CLAUDE_CONFIG_DIR` rather than pointing it at `~/.claude`, because Claude reads `$CLAUDE_CONFIG_DIR/.claude.json` and keys its macOS Keychain entry to any directory that is set ([authentication, "Credential management"](https://code.claude.com/docs/en/authentication#credential-management)).
+
 A Pi root can hold several provider logins at once, so the root alone does not say which account a launch spends.
 A pinned Pi launch therefore needs `--model <provider>/<id>` naming a declared provider, and Firstmate also passes `--provider <that provider>` so Pi cannot resolve the model under another signed-in provider.
+
 An unqualified model, an undeclared provider, or a raw Pi launch command, which cannot receive that flag, refuses; Firstmate never guesses a provider.
 
+### Launch scope and sign-in checks
+
 When a file is present, every launch of that runner from this home uses it: ships, scouts, local secondmate agents, raw Claude launch commands, and relaunches.
-A raw Claude launch command whose leading assignments set `CLAUDE_CONFIG_DIR` or one of the credentials a pinned launch unsets, such as `ANTHROPIC_API_KEY`, would override the pin, so it refuses and names the variable; remove the assignment from the raw command, or change or remove `config/claude-account`.
+A raw Claude launch command refuses if its leading assignments set `CLAUDE_CONFIG_DIR` or a credential that a pinned launch unsets, such as `ANTHROPIC_API_KEY`.
+The assignment would override the pin.
+The refusal names the variable; remove that assignment from the raw command, or change or remove `config/claude-account`.
+
 Before any worker endpoint, local copy, or task record exists, and before a relaunch stops the running worker, Firstmate asks the runner itself whether the pinned account is signed in: `claude auth status` for Claude, and `pi auth check --provider <provider> --json --no-refresh` for Pi, falling back to `pi --list-models <provider>` for a provider an extension registers.
 The check runs with only `HOME`, `PATH`, `TMPDIR`, `USER`, `LOGNAME`, and the pinned root in its environment, so a credential variable in firstmate's own environment cannot answer for an empty root.
+
 A pinned Claude launch also unsets the environment credentials Claude ranks above a stored login, such as `ANTHROPIC_API_KEY`, `CLAUDE_CODE_OAUTH_TOKEN`, and the Bedrock and Vertex switches ([authentication precedence](https://code.claude.com/docs/en/authentication#authentication-precedence)).
 Pi ranks a root's stored logins above environment variables, so a pinned Pi launch unsets nothing.
+
 A home that authenticates Claude through environment credentials on purpose should leave the pin absent.
 
+### Failures, reporting, and inheritance
+
 A malformed file, a root that is not a readable directory, or a signed-out account refuses the launch and names the file to fix; Firstmate never falls back to the ambient account and never changes a global login or copies a credential.
 The spawn prints the pin as `account=` (plus `account_provider=` for Pi) and records the same fields in the task record, so the session-start digest shows which account each worker launched on.
+
 Pins are not inherited into secondmate homes: a local secondmate agent launches on the launching home's pin, while the secondmate's own workers read the secondmate home's files.
 A remote secondmate is launched on its host from its own home's configuration, so create the file in that remote home.
+
 [`bin/fm-worker-account-lib.sh`](../bin/fm-worker-account-lib.sh) owns parsing, the sign-in check, and the full list of credentials a Claude launch unsets; [runtime backend verification](verification/runtime-backends.md#worker-account-pin-sign-in-check) records the check against the real runners.
 
 ## Lavish server address (config/lavish-axi-host)
 
 The optional local, gitignored `config/lavish-axi-host` contains one non-empty address without whitespace for the per-machine Lavish server.
 `fm-spawn.sh` exports that address into every new worker and relaunch for opening boards, and the file is inherited into secondmate homes through the primary-authoritative configuration contract.
+
 Once a board exists, the process-event adapter derives the polling address from that board's own saved Lavish session instead; its header owns the lookup contract.
 When the file is absent, worker launches do not add a board address and retain the existing ambient-environment behavior.
+
 Malformed or unreadable values refuse the launch before the worker starts.
 The address selects the existing shared server; it does not authorize starting or stopping the server, and the Lavish startup crash remains a vendor-tool concern.
 
 ## Home brief include (config/brief-include.md)
 
-The optional local, gitignored `config/brief-include.md` carries standing worker instructions that one captain wants on every ship and scout brief, so private brief content needs no edit to a tracked file.
+The optional local, gitignored `config/brief-include.md` adds standing worker instructions to every ship and scout brief.
+This keeps private brief content out of tracked files.
 When the file exists, `bin/fm-brief.sh` appends its text verbatim as the scaffold's last section, `# Home brief additions`, which defers to every other section of the brief, including the ship contract a later scout promotion appends below it.
+
 An absent or blank file changes nothing, while a present path that is not a readable regular file, or text carrying its own `Delivery contract: mode=` line, stops the scaffold before anything is written.
 The text is static and never executed or expanded; secondmate charters never take it, and the file is local to each home rather than part of secondmate inherited configuration.
+
 `bin/fm-brief.sh`'s header owns the placement rule and its safety argument.
 
 ## Worker launch environment (config/launch-env-allowlist)
 
 The optional local, gitignored `config/launch-env-allowlist` limits the ambient environment passed to newly launched workers, scouts, and secondmates, including relaunches.
 With no file, ambient inheritance remains unfiltered: selected harness markers are cleared, while the provider, long-lived terminal daemon, and shell initialization determine which other variables reach the worker.
+
 Do not assume every worker inherits the invoking Firstmate process's current environment.
 The file is inherited into secondmate homes through the [primary-authoritative configuration contract](../.agents/skills/secondmate-provisioning/SKILL.md).

 Changes apply to subsequent launches; existing processes keep their environment.

 Blank lines and lines beginning with `#` are allowed.

 ## Typed dispatch resolution (.env TYPESAFE_API_KEY)
 
 `bin/fm-dispatch-resolve.sh` resolves one concrete crewmate or scout profile from a written brief with typesafe.ai's System One model (Jev), so the rule match that firstmate otherwise reasons out in its own context becomes one short tool turn.
 It is off unless `TYPESAFE_API_KEY` is non-empty in the calling environment or the home's gitignored `.env` holds a `TYPESAFE_API_KEY=` line; the environment wins, matching the Relay and mail-plane contracts, and the Relay accessor in `bin/fm-env-lib.sh` reads the line.
+
 Off means one `dispatch-resolve: off` line on stderr, nothing on stdout, exit 0, and no network call, so firstmate dispatches exactly as it does without the tool.
 This section is the single owner of the tool's operator contract; the script header owns its exact flags and output lines, and "Crew dispatch profiles" above owns the declared rule and profile fields it applies.
+
 Rules come only from the effective home's `config/crew-dispatch.json`; `FM_CONFIG_OVERRIDE` selects the config directory for tests and specialized setup like the other scripts.
 
 ```sh
 bin/fm-dispatch-resolve.sh data/<id>/brief.md --project <name>        # TOON block on stdout
 ```
 
+**When firstmate invokes the resolver**
+
 Firstmate invokes the resolve path directly after writing the brief, without a preflight; the absent-key off line is handled exactly like every other non-clear outcome.
+
+**What the model receives**
+
 When on and at least one rule exists, the tool sends the project name and the brief's task-specific text as state and asks one Choice question whose options are every rule's `when` plus the fixed neutral option for no matching rule; the model never sees quota, catalogs, `why`, `use`, approvals, or confidence floors.
 The task-specific text is the brief's `## Captain's intent` and `## Firstmate spec` sections under `# Task` that `bin/fm-brief.sh` scaffolds, read by the same parser that feeds `fm-spawn.sh` validation and the no-mistakes `--intent` contract; a brief with neither section is sent whole.
+
 When the sections are sent from a scout brief, the line `Brief kind: scout (report only)` comes first, taken from the scaffold's scout contract line; ship briefs and briefs sent whole get no kind line.
 A ship brief's delivery mode is deliberately not sent, because in live runs naming it pushed a routine ship brief toward the hardest tier (see [the verification record](verification/dispatch-resolve.md)).
+
 The scaffold's standard setup, rules, and definition-of-done text is the same in every brief, so leaving it out keeps its safety language from reading as a signal about the task.
+
+**Missing or invalid rules**
+
 An absent rules file, a default-only file, or `rules: []` returns the non-clear reason `no rules to match` without a model or quota request, leaving firstmate's existing routing in control; an existing but unreadable or malformed rules file, including a broken symlink, remains an actionable exit 2 configuration error.
-Everything after the answer runs in code: the confidence floor, the matched rule's `approval` and `floor`, each candidate's `provider` and `floor`, every applicable account-wide and model/product row from one `quota-axi --json` snapshot, and the numeric `spendPriority` argmax over candidates using each candidate's limiting row.
+
+**Checks performed after the answer**
+
+After the answer, code applies all remaining checks and ranking:
+
+- The confidence floor and the matched rule's `approval` and `floor`.
+- Each candidate's `provider` and `floor`.
+- Every applicable account-wide and model/product row from one `quota-axi --json` snapshot.
+- The numeric `spendPriority` argmax over candidates, using each candidate's limiting row.
+
 The [shared quota library](../bin/fm-quota-axi-lib.sh) accepts schema 5 and schema 6 and implements the [account-matching contract](../.agents/skills/quota-array-dispatch/SKILL.md#1-eligibility).
-An expanded provider with no matching account row leaves the candidate eligible but unranked.
-Known applicable rows from a provider with partial quota semantics remain rankable; rows whose own status is not known remain unrankable.
-A rule that declares `min_confidence` is checked against that rule's own probability, whether it is the picked option or a runner-up, so a runner-up never needs weaker support than it would as the pick.
-A picked rule without `min_confidence`, and the neutral option, keep the global 0.6 floor on the answer's confidence exactly as before, so a file with no declared floors behaves as it did.
-When the picked rule declares its own floor and its probability is below it, the tool takes the most probable other option whose probability clears that option's floor (a rule's `min_confidence`, otherwise 0.6), prints a `fallback:` line naming both floors, and resolves that rule as though it had been picked; no qualifying option, or two equally probable ones, is `ambiguous`.
-Any applicable `exhausted_now` row or known zero bound makes that candidate ineligible, and a known profile-floor shortfall does the same before unrelated quota uncertainty is considered.
-Missing or nonnumeric `spendPriority` evidence is never ranked, and every candidate is printed beside its evidence or the reason it was not rankable, including on ambiguous and approval-gated outcomes that emit no profile.
-On the opted-in path, duplicate concrete profiles with the same harness, model, and effort inside one rule or the default array are configuration errors rather than ties.
-The result is one of `clear` (a `profile:` line ready for `fm-spawn.sh`), `ambiguous` (confidence below the floor with no runner-up taken), `escalate` (an approval-gated rule, unverifiable rule floor, nothing rankable, or a genuine tie), or `error` (API, network, malformed response metadata, rendering, or quota-axi failure), and every one of them exits 0.
-Response probabilities must contain exactly every offered choice, use numeric values from 0 through 1, and sum to approximately 1 within 0.01.
-Only a usage or configuration error exits 2: an unreadable brief, an existing but unreadable or malformed canonical rules file, or missing `jq`, each reported and never selected around.
-Missing `curl` is a normal structured `error` outcome with exit 0 so firstmate uses today's routing.

+
+**Firstmate retains the dispatch decision**
+
 The tool never replaces firstmate's judgment, `quota-array-dispatch`, the captain-approval gate, or `fm-spawn.sh` validation; `AGENTS.md` section 4 owns what firstmate does with each outcome.
 By accepted design, a `clear` result does not enforce catalog/authentication, reasoning-class, or completion-runway gates.
+
 Firstmate passes its profile line unless it states a reason to override, such as the brief's reasoning class or an eligible-unranked-candidate note; every non-clear result returns to the full existing intake.

 ## Toolchain
 
 On session start the first mate detects what its required toolchain is missing or too old and lists each problem with either an exact install command or manual instructions.
 It installs automatically supported tools only after you say go; manual-only tools remain for you to install from the printed instructions.
+
 Required tools come in two parts: a universal toolchain every home needs regardless of backend, and a per-backend delta that follows the runtime backend actually resolved for this home.
-The essential universal toolchain is node, git, gh with GitHub auth via `gh auth login`, no-mistakes v1.46.0 or newer, compatible gh-axi, chrome-devtools-axi, compatible tasks-axi per "Backlog backend" above, and compatible quota-axi.
+
+**Universal requirements**
+
+Every home requires:
+
+- node and git.
+- gh, with GitHub authentication through `gh auth login`.
+- no-mistakes v1.46.0 or newer.
+- Compatible gh-axi.
+- chrome-devtools-axi.
+- Compatible tasks-axi, as specified in "Backlog backend" above.
+- Compatible quota-axi.
+
 [`bin/fm-bootstrap.sh`](../bin/fm-bootstrap.sh) owns the axi-family floor policy and the gh-axi and lavish-axi floors, while [`bin/fm-tasks-axi-lib.sh`](../bin/fm-tasks-axi-lib.sh) and [`bin/fm-quota-axi-lib.sh`](../bin/fm-quota-axi-lib.sh) hold their own tools' floor constants.
 This section is the single owner of that universal toolchain list; backend guides' prerequisites point here and add only their backend-specific tools.
+
 In that list, no-mistakes runs the validation pipeline, gh-axi and chrome-devtools-axi cover GitHub and browser operations, and tasks-axi plus quota-axi back backlog mutations and quota-aware array dispatch.
 Lavish is a presentation-only dependency for visual decisions and reports; nonvisual work can proceed with plain text when it is unavailable.
+
+**Backend requirements**
+
 The per-backend delta is required only for the backend resolved from `FM_BACKEND`, then `config/backend`, then runtime auto-detection, then default `tmux`, so a home is never told to install a tool an inactive backend or feature would need.
-That delta is owned in code by `fm_backend_required_tools` in `bin/fm-backend.sh`: the resolved backend's own session-provider CLI (`tmux`, `herdr`, `zellij`, `orca`, or `cmux`), `jq` for the JSON-emitting adapters (`herdr`, `zellij`, `cmux`) whose spawn and liveness paths parse the backend's JSON output, and the `treehouse` worktree provider for every session-provider-only backend (`tmux`, `herdr`, `zellij`, `cmux`).
+`fm_backend_required_tools` in `bin/fm-backend.sh` owns the backend additions:
+
+| Resolved backend | Additional tools |
+| --- | --- |
+| `tmux` | `tmux`, `treehouse` |
+| `herdr` | `herdr`, `jq`, `treehouse` |
+| `zellij` | `zellij`, `jq`, `treehouse` |
+| `orca` | `orca` |
+| `cmux` | `cmux`, `jq`, `treehouse` |
+
+The JSON-emitting adapters (`herdr`, `zellij`, `cmux`) need `jq` because their spawn and liveness paths parse backend JSON.
+Every session-provider-only backend (`tmux`, `herdr`, `zellij`, `cmux`) uses `treehouse` for worktrees.
+
 Backend tool availability uses the adapter's own executable resolver, so bootstrap and spawn agree on supported non-`PATH` locations such as cmux's bundled CLI.
 An unknown resolved backend emits `BACKEND_INVALID` and blocks dispatch instead of silently dropping its dependency delta or falling back to tmux.
+
 Orca provides both the task worktree and terminal endpoint (see "Runtime backend" above), so `backend=orca` requires only `orca` on top of the universal toolchain and skips both `treehouse` and every other backend's session CLI.
 A herdr, zellij, or cmux home is therefore never told `tmux` is missing, and the `treehouse` durable-lease upgrade check runs only for the backends that actually use treehouse.

+**Feature-specific requirements**
+
+- When `config/crew-dispatch.json` exists, bootstrap also requires `jq` for dispatch profile validation.
+- When Relay is opted in, bootstrap also requires `curl` and `jq` before arming the relay poll shim.
+
+**Missing-tool diagnostics**
+
 `tasks-axi` and `quota-axi` are essential bootstrap tools in every profile.
-An absent or incompatible `tasks-axi` reports `MISSING: tasks-axi (install: npm install -g tasks-axi)`; when `config/backlog-backend` is not `manual`, a home with a configured non-markdown adapter or a markdown backlog refuses lifecycle mutation until compatible `tasks-axi` is on `PATH`, while a manual-backend home keeps its backlog hand-edited.
-An absent or incompatible `gh-axi` reports `MISSING: gh-axi (install: npm install -g gh-axi && gh-axi setup hooks)`.
-An absent or incompatible `lavish-axi` reports `PRESENTATION_UNAVAILABLE` with its required floor, install command, and explicit text fallback; [`bootstrap-diagnostics`](../.agents/skills/bootstrap-diagnostics/SKILL.md) owns the response and compatibility check before visual use.

+
+- An absent or incompatible `tasks-axi` reports `MISSING: tasks-axi (install: npm install -g tasks-axi)`; when `config/backlog-backend` is not `manual`, a home with a configured non-markdown adapter or a markdown backlog refuses lifecycle mutation until compatible `tasks-axi` is on `PATH`, while a manual-backend home keeps its backlog hand-edited.

+
+**Checkout diagnostics**
+
 Bootstrap also reports a `TANGLE:` line when `FM_ROOT` is on a named non-default branch; follow the printed checkout remediation rather than treating it as an installable tool problem.
 In a read-only session that did not get the fleet lock, the same line is advisory and omits the checkout command.
+
+**Project refresh at startup**
+
 The locked session-start deferred network stage runs bootstrap's best-effort project clone refresh through `fm-fleet-sync.sh`; [`fm-bootstrap.sh`'s header](../bin/fm-bootstrap.sh) owns the exact clone-refresh overlap, liveness-before-convergence, per-mate concurrency, ordered diagnostic replay, and sequential-fallback contract.
-It emits `FLEET_SYNC:` for skipped refreshes that may matter, recovered self-heals, and `STUCK:` alarms.
-Normal completed runs keep local-only and no-origin skips silent.
-If bootstrap kills a timed-out refresh, it replays any completed `fm-fleet-sync.sh` output before the aggregate timeout skip so no finished result is lost.

+- If bootstrap kills a timed-out refresh, it replays any completed `fm-fleet-sync.sh` output before the aggregate timeout skip so no finished result is lost.
+
+**Stale Git lock recovery**
+
 A killed refresh (or a teardown process kill) can leave an orphaned `.git/packed-refs.lock` in a clone, which makes the next refresh's fetch fail with Git's `Unable to create '...packed-refs.lock': File exists`.
 On that signature only, `fm-fleet-sync.sh` retries the fetch with a bounded wait for the lock to self-clear, then removes the lock and retries once more only when it can prove the lock stale, exactly like the `fm-teardown.sh` `index.lock` recovery.
+
 It never removes a live lock, leaves any other failure shape untouched, and prints every wait, retry, and removal to stderr plus a one-line `recovered:` summary to stdout on success so that this session-start relay still surfaces the recovery.
+
+**Secondmate sync at startup**
+
 The same deferred network stage performs guarded tracked-file sync and propagates declared inherited local material into each validated live home under that sequencing contract.
 Local routes use direct guarded filesystem operations, while remote routes delegate sync and allowlisted transfer through their configured SSH host without probing any unconfigured fleet.
-It emits `SECONDMATE_SYNC:` only when a home was skipped for an actionable sync reason, inheritance failed, or a divergent shared captain-preference copy was quarantined.
-When a running home advances and its loaded instruction surface (`AGENTS.md`, `bin/`, or `.agents/skills/`) changed, bootstrap sends the re-read nudge itself through the stable `fm-<id>` selector and reports the exact completed send as `BOOTSTRAP_INFO:`.
-If that send fails, bootstrap keeps an idempotent retry marker and emits `NUDGE_SECONDMATES:` with the failure reason.
-The same bootstrap run emits `SECONDMATE_LIVENESS:` only when a registered secondmate is skipped or its relaunch fails; already-live and successfully relaunched secondmates are handled silently.
+

+
+**Push inherited configuration during a session**
+
 For a mid-session inherited local-material edit where tracked-file sync is not needed, run `bin/fm-config-push.sh`.
 It uses the same live secondmate discovery and propagation helper as bootstrap; its [help](../bin/fm-config-push.sh) owns reporting and exit semantics, and [`fm_config_inherit_items`](../bin/fm-config-inherit-lib.sh) declares the inherited items.
-When an allowlisted config item changes for an already-running local home, it sends the literal-content reread pointer described in [`secondmate-provisioning`](../.agents/skills/secondmate-provisioning/SKILL.md); unchanged allowlisted config sends no pointer unless a previous delivery is pending.
-A changed remote home instead receives one durably recorded marked re-read instruction after the allowlisted bytes have transferred because primary-local generation paths are not meaningful on another host.
-The locked bootstrap inheritance pass uses the same placement-specific behavior; see `secondmate-provisioning` for the single contract owner.
-That live discovery starts from `state/*.meta` records with `kind=secondmate`; `data/secondmates.md` only backfills `home=` for older or incomplete meta records.
-Skipped items, such as a destination checkout that does not yet gitignore the item, are visible warnings but not hard failures.

 ## Mail plane (.env)
 
 The mail plane (bin/fm-mail.sh) reads unseen IMAP messages and sends one SMTP message.
+
+**Polling and delivery guarantees**
+
 Its `poll` command surfaces each new message as a durable `check: mail <uid>` wake, which is also what the standing received-mail check runs each watcher cycle.
 Poll emission is exactly-once-recovering: a published wake always carries a durable journal record, and a poll interrupted before recording its uid is healed from that journal, so inbound mail is never silently missed.
+
 A duplicate wake is possible if the process is killed between the queue append and the journal write and the drain acknowledges that row before the next poll heals it, or under a triple write fault that leaves a queued row with no durable record; neither case drops mail.
+
+**Connection and activation**
+
 IMAP and SMTP use implicit TLS on the default ports 993 and 465 (`IMAP4_SSL` / `SMTP_SSL`).
 STARTTLS and port 587 are not supported.
+
 It is off unless the home's gitignored `.env` provides the connection values.

 The per-poll wake cap bounds the wakes of one `poll` run; header fetches scan a larger bounded window of new unseen uids plus already-surfaced retry-set uids, so a flood or large backlog still makes bounded progress every poll, keeping the durable wake queue bounded without ever dropping mail.

+
 Destructive, irreversible, or security-sensitive asks are flagged for trusted-channel confirmation instead of being executed from a public mention.
 The relay uses owner-only routing: a mention delivered to a home is from that home's owner/captain, while its surrounding conversation context may still include other public accounts.
+
+**Endpoint and environment overrides**
+
 `FMX_RELAY_URL` is optional and defaults to `https://myfirstmate.io`, mainly for developers pointing at a local relay.
 For direct client invocations, environment values override `.env`; bootstrap activation still keys off `.env` presence so watcher artifacts are explicit local opt-in state.
+
 `FMX_ENV_FILE` can point direct poll/reply client invocations at another `.env`-style file, but it does not change bootstrap activation.
 
 To turn it on:
 
 1. Sign in at [myfirstmate.io](https://myfirstmate.io) with X or Discord.
 2. For the Discord surface, use the dashboard's install link to add the myfirstmate bot to a server you administer; the X surface needs no install step.
+
 3. Copy the pairing token from the dashboard into this firstmate home's gitignored `.env` as `FMX_PAIRING_TOKEN=<token>`.
 4. Start a new firstmate session so bootstrap picks the token up, then mention `@myfirstmate` on X or mention the bot in a server where it is installed.
 
 The dashboard owns account creation, identity linking, bot installation, and token issuance; this document owns only what the local firstmate home does with the token once it is in `.env`.
 
+**Generated state and watcher cadence**
+
 The locked session-start bootstrap step turns the token into local generated state.
 It writes `state/x-watch.check.sh`, a byte-static identity shim for `bin/fm-x-poll.sh`, and `config/x-mode.env`, which exports `FM_CHECK_INTERVAL=30` for watcher processes in that home.
+
 The watcher accepts the shim only when its bytes match the expected generated content, then invokes the trusted repository poll script directly instead of executing state-file source.
-This section is the single owner of the Relay cadence contract: a Relay instance polls every 30 seconds instead of the default 300, only a Relay instance speeds up because a non-Relay home has no `config/x-mode.env`, and the session-start supervision operating block includes the cadence instruction when that file exists.
+This section owns the Relay cadence contract:
+
+- A Relay instance polls every 30 seconds instead of the default 300.
+- A non-Relay home has no `config/x-mode.env`, so its cadence does not change.
+- When that file exists, the session-start supervision operating block includes the cadence instruction.
+
 The active primary-harness supervision protocol owns how that sourced cadence reaches the watcher process.
+
+**Apply cadence changes**
+
 Because `bin/fm-watch.sh` reads `FM_CHECK_INTERVAL` only at process start, a cadence transition - opt-in while a watcher is already running, or opt-out - is applied by restarting the home-scoped watcher through the emitted harness protocol; bootstrap deliberately never restarts the watcher itself.
 While a legacy daemon flag is active the daemon owns the watcher and its default cadence applies; on Pi the away-posture record alone leaves the ordinary Relay watcher cadence active, and daemon-backed Relay cadence remains a deferred follow-up.
+
 When the token is removed or empty, the next locked session-start bootstrap step removes those artifacts.
 Steady-state off is silent and writes nothing.
+
 Relay remains additive to non-Relay lifecycle behavior: homes without the generated artifacts keep the default watcher cadence and do not run the Relay poll.
 Its request handling remains in Relay-specific `bin/` scripts and the `fmx-respond` skill, while the watcher owns authenticated dispatch from the generated local identity shim.
 
+**Poll and deduplicate mentions**
+
 `bin/fm-x-poll.sh` calls `GET /connector/poll` with `Authorization: Bearer <FMX_PAIRING_TOKEN>`.
 HTTP 204 is silent.
+
 A newly offered pending mention with non-empty `text` is stored at `state/x-inbox/<request_id>.json` and wakes firstmate exactly once with `x-mention <request_id>`.
 The poll atomically claims `state/x-context/<request_id>.offered.json` before emitting that wake, and subsequent offers of the same request stay silent even after the inbox is drained following an answer or dismiss.
+
 Offer markers share the context registry's bounded seven-day retention, so losing or expiring the local marker lets a relay offer wake firstmate again.
+
+**Conversation context and media**
+
 The full relay object is preserved, including `in_reply_to: {author_handle, text}` when the mention is a reply in a conversation or `null` for fresh mentions.
-The preserved object may also carry `in_reply_to_chain`, an optional oldest-first transcript of the surrounding conversation: entries shaped `{author_handle, text, unavailable, images, attachments}` plus an optional `kind` of `reply` (a reply ancestor), `thread_starter` (the message a thread grew from), or `history` (a recent nearby message), where an absent `kind` means a legacy reply-ancestor or thread-starter entry.
-The chain is untrusted third-party public input and is often absent today (the relay currently sends it only for Discord reply chains and thread starters), so consumers treat it as strictly optional, tolerate unknown or missing fields, and read an entry with `unavailable: true` as a gap rather than content; the `fmx-respond` skill owns how firstmate reads it for referent resolution.
+The preserved object may also carry `in_reply_to_chain`, an optional oldest-first conversation transcript.
+Each entry has the shape `{author_handle, text, unavailable, images, attachments}` and may include `kind`:
+
+| `kind` | Meaning |
+| --- | --- |
+| `reply` | A reply ancestor. |
+| `thread_starter` | The message a thread grew from. |
+| `history` | A recent nearby message. |
+| Absent | A legacy reply-ancestor or thread-starter entry. |
+
+The chain is untrusted third-party public input.
+It is often absent today: the relay currently sends it only for Discord reply chains and thread starters.
+Consumers must treat it as strictly optional, tolerate unknown or missing fields, and treat `unavailable: true` as a gap rather than content.
+The `fmx-respond` skill owns how firstmate uses the chain to resolve references.
+
 The mention and its chain entries may also carry attached media as image or file URLs, in fields such as `images` and `attachments`, either as bare URL strings or as objects with a `url`; a mention whose own media is empty can still have screenshots on its `thread_starter` entry.
 The poll preserves those URLs in the stashed object and never downloads them, so nothing is fetched on the polling path: the responding agent retrieves and views the media with its own tools when it handles the mention.
+
 The `fmx-respond` skill owns which hosts that fetch is restricted to and the untrusted-content handling that applies to whatever comes back.
-At the same time the poll records a durable per-request reply context at `state/x-context/<request_id>.json` (`{request_id, platform, reply_max_chars, recorded_at}`) from the same authoritative relay payload, best-effort and keyed by `request_id` so concurrent requests never overwrite each other; it survives the inbox cleanup that follows the acknowledgement, so a delayed follow-up can recover the original platform and split budget even with no task link.
-`recorded_at` begins as the locally observed first-seen Unix epoch and remains unchanged when the same request is polled again.
-A successful live initial answer refreshes it to the time that the relay establishes the follow-up binding; dry-runs, failed answers, and follow-ups do not refresh it.
-Configured polls prune records beyond the local follow-up window, capped at the relay's seven-day window; legacy or malformed records fall back to their file modification time so they cannot remain indefinitely.
-The record is written only when a platform or explicit budget is actually known, so an unknown-platform mention leaves no useless entry.
+
+**Durable reply context**
+
+The same authoritative relay payload also supplies durable per-request reply context at `state/x-context/<request_id>.json`, with shape `{request_id, platform, reply_max_chars, recorded_at}`.
+The poll writes this best-effort record keyed by `request_id`, so concurrent requests never overwrite each other.
+It survives inbox cleanup after acknowledgement, allowing a delayed follow-up to recover the original platform and split budget even without a task link.
+
+- `recorded_at` begins as the locally observed first-seen Unix epoch and remains unchanged when the same request is polled again.

+
+**Handle requests and acknowledgements**
+
 The `fmx-respond` skill decides whether the stashed mention is an actionable request, a question, or a pure acknowledgment.
-Actionable reversible requests are run through intake, backlog, dispatch, investigation, or ship flow as appropriate.
-If the work completes in that turn, the public reply reports the outcome.
-If the request spawns a longer-running task, firstmate posts an acknowledgement through the normal answer endpoint, links the task to the mention with `bin/fm-x-link.sh`, and posts up to three completion follow-ups on genuine milestones, finishing with a `--final` one for ordinary Relay-linked work. When a typed promised-final commitment is registered, `bin/fm-public-followup.sh` owns the terminal reply and clears the legacy link after its receipt is validated.
-That link stores optional reply-platform context so Discord-originated follow-ups keep Discord's larger message budget after the inbox file has been drained.

+
+**Resolve the reply platform and budget**
+
 Platform/budget resolution is layered and independent of the task link: a per-axis `FMX_REPLY_PLATFORM` / `FMX_REPLY_MAX_CHARS` override (how `bin/fm-x-followup.sh` passes a recorded link's context) wins.
-For either axis without an override, `bin/fm-x-lib.sh:fmx_resolve_reply_context` owns the source order: the durable per-request registry is consulted first, then the still-present inbox payload, then - for a follow-up posted live by request_id - an authoritative relay lookup via `POST /connector/request-context` (`{request_id}` in, `{platform, reply_max_chars}` back).
+For either axis without an override, `bin/fm-x-lib.sh:fmx_resolve_reply_context` consults these sources in order:
+
+1. The durable per-request registry.
+2. The still-present inbox payload.
+3. For a follow-up posted live by request_id only, an authoritative relay lookup through `POST /connector/request-context`: `{request_id}` in, `{platform, reply_max_chars}` back.
+
 This is what keeps a delayed request-id follow-up on the original platform's budget even after the inbox is drained and with no task link surviving; the relay step is confined to the live follow-up path so the answer path and every dry-run stay network-free.
-The link is home-local by construction, because it lives in that home's own `state/<task-id>.meta`: work routed to a secondmate has no record here, so `bin/fm-x-link.sh` refuses it, names the registered secondmate home the task was found in when it can, and points at the promised-final path (`bin/fm-public-followup.sh register ... --work-home secondmate:<id>`), which is the only follow-up mechanism that binds work in another home.
-`bin/fm-x-link.sh` follows the same ordering when recording a fresh link's context and requires `jq`; its request-context lookup is best-effort: no token or `curl`; a non-2xx response; an unresolved response; or a relay version without that endpoint leaves the context unknown.
-In that case the link is still recorded but `bin/fm-x-link.sh` prints a loud warning; and when either a follow-up's platform or explicit budget cannot be authoritatively resolved from any source, `bin/fm-x-reply.sh` refuses it (fail-safe exit 8) rather than posting with a local default - firstmate holds and retries it once both values are recoverable.
+
+**Link tasks and handle missing context**
+
+The link lives in the current home's `state/<task-id>.meta`.
+Work routed to a secondmate has no record here, so `bin/fm-x-link.sh` refuses to link it.
+When possible, the refusal names the registered secondmate home containing the task.
+
+It also points to `bin/fm-public-followup.sh register ... --work-home secondmate:<id>`.
+This promised-final path is the only follow-up mechanism that binds work in another home.
+`bin/fm-x-link.sh` uses the same order when recording a fresh link's context and requires `jq`.
+Its request-context lookup is best-effort.
+Any of these conditions leaves the context unknown:
+
+- No token or `curl`.
+- A non-2xx response.
+- An unresolved response.
+- A relay version without that endpoint.
+
+The link is still recorded, but `bin/fm-x-link.sh` prints a loud warning.
+If either the follow-up platform or explicit budget cannot be authoritatively resolved from any source, `bin/fm-x-reply.sh` refuses with fail-safe exit 8.
+Firstmate holds the follow-up and retries once both values are recoverable; it never posts with a local default.
+
+**Carry a link to a successor task**
+
 Fresh links start with `x_followups=0` and the current timestamp; when relinking the same relay request onto a successor task, pass paired `--carry-count <n> --carry-ts <epoch>` flags plus any prior `x_platform=` and `x_reply_max_chars=` as `--carry-platform <x|discord> --carry-max <n>` so the successor preserves the already-consumed follow-up count, original 7-day window, and reply split budget.
+
+**Dismiss mentions**
+
 Pure acknowledgments or mentions with nothing to answer are dismissed through `bin/fm-x-dismiss.sh` before the local inbox file is cleared.
 Dismiss sends `POST /connector/dismiss` with `{request_id}`, posts no text, and tells the relay to drop the request instead of re-offering it or falling back to an offline auto-reply; on success it clears that request's durable reply-context record, while the separate offer marker remains for its bounded retention so a brief relay re-offer stays silent.
+
+**Poll errors**
+
 Relay auth or config problems are reported once as `x-mode-error ...` until recovery.
 A failed durable offer claim is likewise reported once as `x-mode-error cannot record mention offer` and remains deduplicated through quiet no-pending polls until a later offer confirms an existing valid marker or claims a new one.
+
+**Post replies and follow-ups**
+
 Live replies are posted by `bin/fm-x-reply.sh`, which sends `POST /connector/answer` with `{request_id,text}` for one-message replies.
 Add `--image <path>` to attach one local PNG, JPEG, GIF, WebP, BMP, or TIFF as `{media_type,data_base64}` in the relay's optional `image` object.
+
 Completion follow-ups use `bin/fm-x-followup.sh`, which checks the local `state/<id>.meta` link and sends the same payload shape through `POST /connector/followup` by calling `bin/fm-x-reply.sh --followup`, up to three times per link within the window.
 Add `--image <path>` there too when a completion follow-up should carry an image.
-A successful post increments the local `x_followups=` counter and keeps the link, unless `--final` was passed or the new count reaches the cap, in which case the link is cleared instead; a failed post leaves the link and counter untouched so it can be retried.
-The relay itself rejects a follow-up past its own cap or window with HTTP 409 and may include `{"error":"followup_unavailable"}` in the response body; the client surfaces any follow-up 409 as a distinguishable exit code and uses the body marker only for a sharper diagnostic.
-`fm-x-followup.sh` treats that exit exactly like a locally-detected expiry - clearing the link and skipping quietly rather than retrying - so an older single-follow-up relay or an already-exhausted binding degrades gracefully.
-It treats `fm-x-reply.sh`'s fail-safe refusal (exit 8: platform or explicit budget unresolved) differently: that is a retryable hold, so the link is KEPT and the follow-up is retried once both values can be recovered, never posted with a local default.
-Past-window relay rejections are only guaranteed while the expired binding row still exists on the relay side; after its cleanup sweep, a very-late follow-up call may instead see a benign no-op 200, which is why the local window and cap pruning remains the primary guard.
-Reply splitting is platform-aware: an explicit relay platform field (`reply_platform`, `platform`, `target_platform`, `source_platform`, or `provider`) wins, otherwise a legacy `tweet_id` beginning with `discord:` selects Discord and a numeric `tweet_id` selects X.
-An explicit relay limit field (`reply_max_chars`, `reply_max_characters`, `message_max_chars`, `message_limit`, or `max_chars`) wins over the platform defaults.
-If the reply exceeds the selected budget, the client splits it into a numbered thread on fenced-code, paragraph, line, and word boundaries and sends `{request_id,text,texts}`, where `texts` is the ordered chunk list and `text` remains the first chunk for older relays.
-When `--image <path>` is present on a split reply, the image rides the first/opener message and later chunks stay text-only.
-`FMX_X_REPLY_MAX_CHARS` defaults to 280 and clamps to a minimum of 50; `FMX_DISCORD_REPLY_MAX_CHARS` defaults to 1900, clamps to a minimum of 50, and resets values above Discord's 2000-character limit back to 1900.
-`FMX_X_THREAD_MAX` defaults to 25 and caps oversized reply threads for every platform, marking the last retained message with an ellipsis when truncation is needed.
-`FMX_FOLLOWUP_MAX_AGE_SECS` defaults to 604800 (7 days) and controls the local completion follow-up window; `FMX_FOLLOWUP_MAX_COUNT` defaults to 3 and controls the local follow-up cap.
+
+**Follow-up success, expiry, and retry**
+
+- A successful post increments the local `x_followups=` counter and keeps the link, unless `--final` was passed or the new count reaches the cap, in which case the link is cleared instead; a failed post leaves the link and counter untouched so it can be retried.

+**Split replies by platform**
+
+- Reply splitting is platform-aware: an explicit relay platform field (`reply_platform`, `platform`, `target_platform`, `source_platform`, or `provider`) wins, otherwise a legacy `tweet_id` beginning with `discord:` selects Discord and a numeric `tweet_id` selects X.

+
+**Reply and follow-up limits**
+
+| Setting | Default | Limit or behavior |
+| --- | --- | --- |
+| `FMX_X_REPLY_MAX_CHARS` | 280 | Clamps to a minimum of 50. |
+| `FMX_DISCORD_REPLY_MAX_CHARS` | 1900 | Clamps to a minimum of 50; values above Discord's 2000-character limit reset to 1900. |

+| `FMX_FOLLOWUP_MAX_AGE_SECS` | 604800 (7 days) | Local completion follow-up window. |
+| `FMX_FOLLOWUP_MAX_COUNT` | 3 | Local follow-up cap. |
+
+**Preview with dry-run**
 
 Set `FMX_DRY_RUN` to preview replies and dismissals without posting.
 Truthy means anything except unset, empty, `0`, `false`, `no`, or `off`; an explicit environment value wins over `.env`.
-In dry-run, `fm-x-reply.sh` records the would-be payload to `state/x-outbox/<request_id>.json`, including `texts` for a thread and an `endpoint` marker for follow-up previews, prints a `DRY RUN` summary to stderr, echoes the `request_id`, and exits 0.
-When an image is attached, the dry-run record uses compact `{media_type, bytes, source_path}` metadata instead of writing the base64 bytes.
-In dry-run, `fm-x-dismiss.sh` records `{request_id, endpoint:"dismiss"}` to the same outbox path, prints a `DRY RUN` summary, echoes the `request_id`, and exits 0.
-The live answer and follow-up bodies intentionally stay the same shape, including optional `image`; the relay distinguishes them by endpoint, and dismiss stays `{request_id}`.
-These paths need `jq` to build the JSON payload, but they run before token and network checks, so they need neither `FMX_PAIRING_TOKEN` nor `curl`.

 ### Promised public replies (state/public-followup)
 
 A relay request that spawns real work can leave firstmate owing a specific public reply in a specific thread.
 That promise is a typed `kind=public-followup` obligation whose state machine is owned entirely by `tasks-axi public-followup`, while the full private conversation context stays only in `state/x-context/`.
+
 Firstmate's bounded registration retains the obligation's public-safe request binding so a delivered loop can be rechained without the original inbox.
 `bin/fm-public-followup.sh` is firstmate's side: it registers a commitment, reconciles typed terminal work results into it, posts the final reply through `bin/fm-x-reply.sh --followup`, and explicitly rechains or retires the retained loop.
+
 Run `bin/fm-public-followup.sh --help` for the exact subcommands and flags.
 
-Registration is what creates this home's private transport under `state/public-followup/` (mode 0700): `registry/` for the bounded private binding of each open public loop (the record survives delivery, stamped `state=delivered`, and is removed only by `retire`), `events/` for typed terminal results awaiting reconciliation, `consumed/` for the accepted-event ledger, `rejected/` for refusals kept with a one-line reason, `rejection-wakes/` for each refusal's not-yet-raised wake, `retired/` for the mode-0600 reason-and-time receipt written before removal, and `surfaced` for the poll's last-surfaced signature.
-A work home that reports across a machine boundary also gets `outbox/`, described below.
+**Private transport records**
+
+Registration creates this home's private transport under `state/public-followup/` with mode 0700:
+
+| Entry | Purpose and retention |
+| --- | --- |
+| `registry/` | Bounded private binding for each open public loop; survives delivery with `state=delivered`; only `retire` removes it. |
+| `events/` | Typed terminal results awaiting reconciliation. |
+| `consumed/` | Accepted-event ledger. |
+| `rejected/` | Refusals retained with a one-line reason. |
+| `rejection-wakes/` | Each refusal's not-yet-raised wake. |
+| `retired/` | Mode-0600 reason-and-time receipt written before removal. |
+| `surfaced` | The poll's last-surfaced signature. |
+| `outbox/` | Also created in a work home that reports across a machine boundary; described below. |
+
+**Which home posts the reply**
+
 The home that owns the commitment also owns the outward post, because only it holds the relay consent, the request context, and the opaque thread binding.
 Work routed elsewhere reports a typed terminal result with `bin/fm-public-followup-emit.sh` and never looks for the thread; when writing directly into the owning home, that emitter refuses a home with no registration for the named obligation.
+
+**Prepare and validate terminal results**
+
 `bin/fm-public-followup.sh brief` pre-fills every deliverable value the binding determines, such as `report_path=data/<work-id>/report.md`, and states the accepted format of every value it cannot know.
-The emitter validates deliverable values and known required keys before publishing, including the relative `report_path` format, and names correctable mistakes at the work home.
-A direct emit reads the obligation from `tasks-axi`; a staged emit cannot read that remote record, so `brief` supplies its required keys in the printed command.
-If those flags are omitted from a staged command, it still checks values but cannot detect missing keys until the owning home's `consume` rejects the event and queues a rejection wake.
-The [emitter header](../bin/fm-public-followup-emit.sh) and its `--help` own the exact flags and outcome-dependent validation rules.

+
+**Clear legacy links in remote homes**
+
 When that work lives in a REMOTE secondmate home, delivery clears its bound legacy link after validating the public receipt, while retirement clears the link before closing the loop, and both clears run over that route's SSH transport.
-Readable remote state that proves no link exists succeeds without a write, while a present link is cleared only when its Relay request identity matches the registration and the state is writable; an identity mismatch, unreadable or unsafe state, an unavailable write or lock, an older remote copy, or a host that never confirms the clear leaves the loop retained for reconciliation.
+Readable remote state proving that no link exists succeeds without a write.
+A present link is cleared only when its Relay request identity matches the registration and the state is writable.
+Any of these conditions retains the loop for reconciliation:
+
+- An identity mismatch.
+- Unreadable or unsafe state.
+- An unavailable write or lock.
+- An older remote copy.
+- A host that never confirms the clear.
+
+**Duplicate and failed results**
+
 A terminal event's id is derived from its identity tuple, so a duplicate report, a retry, or a replay after restart resolves to the same event and changes nothing.
 When bound work ends failed or parked, its typed failed result remains deliverable even when the promised final expected a merged pull request, so the owed reply carries the honest failure instead of remaining stranded.
 
+**Collect results across machines**
+
 Work bound to a REMOTE secondmate home reports across a machine boundary, where no local path reaches the owning home.
-`bin/fm-public-followup.sh brief` therefore prints that worker the route's own code root and home with `--stage-in`, so the typed result is staged in `outbox/` in the home where the work actually runs rather than written to a path that only exists on the owning machine.
-The owning home collects staged results for open registrations over the same SSH route it reaches that secondmate on, because that transport only runs in the outbound direction: `consume` pulls them into its own `events/` and then reconciles them exactly as it reconciles a local report.
-Non-open registrations owe no result, so `consume` skips them without contacting their routes; an open registration whose reachable route has nothing staged remains pending without an error.
-Collection is non-destructive until the result is durably held, and the staged copy is retired only afterwards, so a dropped connection can never lose a terminal result.
-For an open registration, a work home that cannot be reached is named in `consume`'s output and keeps the promise open; it is never reported as an empty inbox.

+- The owning home collects staged results for open registrations over the same SSH route it reaches that secondmate on, because that transport only runs in the outbound direction: `consume` pulls them into its own `events/` and then reconciles them exactly as it reconciles a local report.
+- Non-open registrations owe no result, so `consume` skips them without contacting their routes; an open registration whose reachable route has nothing staged remains pending without an error.
+- Collection is non-destructive until the result is durably held, and the staged copy is retired only afterwards, so a dropped connection can never lose a terminal result.
+- For an open registration, a work home that cannot be reached is named in `consume`'s output and keeps the promise open; it is never reported as an empty inbox.
+
 Run `bin/fm-public-followup-collect.sh --help` for the staged-result commands the owning home runs over that route.
 
+**Activation and idle cost**
+
 Activation is the same `.env` `FMX_PAIRING_TOKEN` contract as the rest of Relay, with no second flag.
-A home without that token runs one file test and stops: no `tasks-axi` call, no backlog or request-context scan, and no `state/public-followup/` directory.
-Ordinary startup, polling, cleanup, and silent read-side subcommands also produce no output; commands that require an active relay report that configuration error after the same gate.
-A relay-enabled home with no registered commitment stops at an O(1) directory presence check, so the empty state costs no CLI call and adds no periodic scan.

+**Wake on new or rejected results**

 Unreconciled terminal results ride the existing 30-second relay poll rather than a new process or timer: `bin/fm-x-poll.sh` compares the pending-event signature against `surfaced` and wakes firstmate once per new result set.
-A terminal event `tasks-axi` refuses during `consume` is quarantined with a reason naming the specific deliverable, outcome, or missing key where one is identifiable, and the same poll wakes the owning home with a `public-followup rejected <event-id> ...` line carrying that reason.
-The refused event stays pending until that wake is recorded, and a queued wake survives a failed read or write to poll output.
-That makes the wake at-least-once rather than exactly-once: a cleanup that fails after the line was already raised - a wake directory that cannot be written, or a refused event that could not be drained - raises the same refusal again on a later poll.
-A repeat carries the same event id and the same reason as the quarantined rejection, which is how an already-handled refusal is recognized.
-Acknowledge it without re-acting; re-emitting an already accepted corrected result is harmless but redundant because its derived event id is already in the accepted ledger.

 A home can explicitly enable a trusted external `process-event-adapter/1` package without adding package code to Firstmate.
 This is one narrow extension type, not a general plugin or hook system.
+
 [`extension-bindings.md`](extension-bindings.md) owns the manifest, binding, trust, handshake, invocation-envelope, capability, version-compatibility, and authority-boundary contracts.
 `bin/fm-extension.sh --help` and `bin/fm-procevent.sh --help` own exact command mechanics.

 Discovery reads only mode-`0600` bindings under this home's mode-`0700` `config/extensions.d/` directory.
 The current directory, projects, task copies, worker text, environment payloads, and Pi packages are never searched for extensions.
+
 When the directory is absent, ordinary process-event commands perform only a bounded absence check, create no package or extension state, and preserve every built-in adapter path.
 
+**Bind a trusted package**
+
 Binding separates the package's own manifest from this home's explicit enablement.
-`bind` validates the source package, computes every digest, copies the complete tree into the read-only content-addressed `data/extensions/packages/` store, performs the live handshake, and atomically publishes the enabled adapter-name subset.
+`bind` performs these steps:
+

 The operator supplies trust and required consent facts, not hashes.

 `state/extensions/<extension-id>/` is created when binding performs its initial handshake and is that package's home-local working namespace for later verification and invocation.
 `state/extension-invocations/` contains private host-owned exact process-group cleanup records only while an enabled package invocation is starting or running; retirement and reconciliation retain their existing owners until those records prove the group extinct.

 ## Process-to-event sources (state/procevent)
 
 A long-polling external process is registered as a *source* through its adapter, whose header and `--help` own the commands and flags.
 `bin/fm-procevent.sh` owns the generic contract; built-in adapters retain their tracked `bin/fm-procevent-<adapter>.sh` commands, while an explicitly bound external adapter routes through the trusted host contract above.
+
 `bin/fm-procevent-lavish.sh` is the first built-in adapter and wraps only the currently published `lavish-axi poll` interface.
+
+**Open the Lavish artifact first**
+
 Before arming any Lavish source, open its artifact with `lavish-axi` so the saved session identifies the board's server; each poll attempt derives its host and port from that session and refuses missing or invalid session evidence before consuming a staged worker reply.
+
+**Retry interrupted Lavish polls**
+
 That adapter, and only that adapter, retries the one exact transient response a cut-short listener returns while its marks remain available (`error: Lavish Editor poll response was interrupted` with `code: SERVER_ERROR`), up to 12 times with poll starts at least 5 seconds apart, so an internal retry never reaches the runner as a captured result.
 This start-to-start governor is a no-op after a normally blocking poll but caps an immediately returning poll under the shipped defaults independently of the owner lease and registration launch pacing.
+
 Real feedback, ended and missing sessions, any other `SERVER_ERROR`, and that same interruption still standing once the bound is spent are all captured and announced normally; `FM_LAVISH_POLL_RETRY_DELAY` is a bounded 1 to 60 second test override for the interval only, and the runner itself stays adapter-agnostic.
 An already-armed Lavish source keeps its registered listener command until it is retired and armed again, so retire the source, then arm it again to adopt this retry policy.
 
 ### Crew-hosted Lavish review boards
 
+**Arm and confirm a listener**
+
 A live task that hosts a Lavish board owns its listener, so firstmate must never arm that board.
 After opening the artifact as required above, the worker arms it with `bin/fm-procevent-lavish.sh arm <artifact.html> --for <task-id>` and never runs `lavish-axi poll` itself.
+
 `arm` prints `armed` only after the process-event owner confirms this registration generation's listener is running, and otherwise returns nonzero without that line.
-The confirmation is the same live claim or launch-stamp evidence `reconcile` already uses, bounded by `FM_PROCEVENT_LAUNCH_CONFIRM_SECONDS`, and a failed confirmation retires a source that never started unless `retire` refuses because something may still own it, in which case the registration stays for `reconcile` or a human.
-An earlier registration's listener that releases the board inside the confirm window lets the new registration start, and `arm` then reports `armed` as usual.
-When a live listener from an earlier registration of the same board still holds it when the window ends, `arm` exits zero with `still-listening` instead of `armed`, because that earlier listener keeps serving the board and the new registration takes effect only after the source is retired and armed again.
-The arm is refused unless that task id has valid, identity-matching endpoint metadata, because a board whose owner has no endpoint would collect feedback nobody can be told about.

+- The arm is refused unless that task id has valid, identity-matching endpoint metadata, because a board whose owner has no endpoint would collect feedback nobody can be told about.
+
+**Acknowledge a round by re-arming**
+
 The registration persists as one task-owned source record, while each captured nonterminal round remains open until the worker re-arms and the existing handled marker acknowledges that round.
 Re-arm is that acknowledgement and nothing else: the board is armed once while no record exists, and a further arm by the same owner is refused unless an unacknowledged nonterminal round is waiting, so a generation already carrying a reply is never replaced before its listener posts it.
-Re-arm never acquires, releases, or hands off the source claim, and it may carry `--agent-reply-file <path>` whose contents are copied into that generation's own private staging file and handed once to the published `--agent-reply` argument; a re-arm that fails leaves the prior registration and the reply it references exactly as they were, including when the acknowledgement it owes cannot be recorded.
-Posting that reply is best effort by design: the listener consumes the staged file only once its own setup and the board artifact have checked out, so the one loss window is a rare crash between that consume and the call it feeds, which drops that round's reply rather than posting it twice, and nothing here keeps a receipt, retry, or idempotency record - robust reply delivery waits on lavish-axi's exclusive listener.
-The captured result is stored with immutable task-owner routing evidence and delivered directly to that task's steering inbox, without a firstmate `check` wake for the captain's words.
-Filing that steering note away is not acknowledging the round, so while the round stays open every reconcile puts a live note back in the owner's inbox rather than ringing a filed one.
-A task-owned source with an unhandled capture is not relaunched, so delivery failure cannot consume a round and start another poll.
-That record is the only ownership evidence there is, so while any captured round of it is unacknowledged every retirement path refuses - the runner's own terminal retirement and an explicit `retire` alike - and the refusal names the acknowledgement that releases it.
-A terminal result, including `session_ended`, an empty End, or missing, is delivered to the owner with an explicit stop-and-conclude instruction and is never auto-rearmed.
-That round keeps the board with its owner: the source record is not retired while the terminal capture is unacknowledged, so no second armer can take the board, and acknowledging it with `bin/fm-procevent.sh handled <source-id> <sequence>` is what concludes and retires it.
-That conclude retains the registration it is retiring, removes it, then records the acknowledgement and restores the registration if that record cannot be written, so a failed conclude never leaves the round open with its owner gone.
-An interruption between those two durable steps leaves the board unregistered with its terminal round still open, which nothing relaunches and the same `handled` call finishes.
-It concludes only a round that is still open, so a repeated acknowledgement of an already-closed round reports `already-handled` and never touches whatever registration holds the board by then.
-A second armer is refused with the current owner named, and the source list derives `listening`, `round-open`, or `dead` from the claim and handled captures without a second ownership record.
-If the hosting worker cannot be recovered, relaunch a worker to re-host first; guarded firstmate adoption is an explicit last resort only after the old claim is proved dead.
-The cross-home gap between worker rounds remains an accepted residual until lavish-axi's exclusive listener lands.
-The interim crew instruction emitted by `bin/fm-brief.sh` points workers at this arm-and-acknowledge contract.

-The `when` adapter (`bin/fm-procevent-when.sh`) turns this channel into a condition->action primitive: it registers a deterministic condition and a deterministic action once, its blocking child polls the condition without waking firstmate, and a stable true fires the action at most once before one terminal outcome is durably captured and published as a wake that remains eligible for re-announcement until handled.

+Re-arm never acquires, releases, or hands off the source claim.

+- It concludes only a round that is still open, so a repeated acknowledgement of an already-closed round reports `already-handled` and never touches whatever registration holds the board by then.

+- The interim crew instruction emitted by `bin/fm-brief.sh` points workers at this arm-and-acknowledge contract.
+
+**Register deterministic condition and action watches**
+
+The `when` adapter (`bin/fm-procevent-when.sh`) registers a deterministic condition and action once.
+Its blocking child polls the condition without waking firstmate.
+A stable true fires the action at most once.
+One terminal outcome is then durably captured and published as a wake, which remains eligible for re-announcement until handled.
+
 The (condition, action) spec is stored privately under `state/when/` and hash-bound by a trust record the same way `bin/fm-check-register.sh` binds a custom check, while the spec separately binds the resolved action executable's bytes; a mutated or unregistered spec or a changed action executable is refused before the action runs, and that binding is reloaded from disk immediately before each fire rather than trusted from when polling started.
 A repo update that fast-forwards an in-repo action's bytes in place would otherwise desync every already-armed watch's trust binding with no tampering involved; `bin/fm-procevent-when.sh rebind-all` re-hashes and republishes the binding for every registered watch whose action lives under `FM_ROOT`, including one already polling, so it keeps firing across such an update instead of being refused on its next fire.
+
 Every failure path - a mutated spec or action executable, a condition error past its budget, an expired deadline, a failed action, or an earlier fire whose outcome was never captured - produces a terminal captured outcome that wakes firstmate rather than a silent retry, and a durable single-fire marker claimed before the action makes restarts and re-polls unable to fire it twice.
 The adapter automates only the exact deterministic subset: anything needing judgment, and anything destructive, irreversible, or security-sensitive, keeps the ordinary check-fires-then-firstmate-decides flow, and the adapter's header and `--help` own its commands, flags, and outcome document.
 
+**Capture and publish results**
+
 This section is the single owner of the runner's operating contract.
-Process-event commands resolve the state root to its physical directory before validating it and deriving paths, so a home reached through a symlinked ancestor behaves like its physical spelling while an unsafe target directory remains refused.
-Registration writes one private record under `state/procevent/`, and a completed result plus its immutable adapter identity are captured under `state/procevent-inbox/` before any announcement or event can reference it.
-By default, results are published as ordinary `check` wakes carrying the source id and committed result sequence through the existing durable wake queue, so the runner adds no second notification control plane.
-The self-announcing adapter exception and its fail-safe ordering are defined below.
-The watcher delivers a queued result on its ordinary cycle by reporting it as an actionable `check` wake, so a default or fallback publication reaches firstmate through the same rewake path every other wake uses and never waits for a manual drain.
-A queued `check` delivery is reported at most once per captured source and sequence while any records for that key remain queued.
-A durable handled acknowledgement stops future source re-announcement, while a record already queued remains under the durable queue's authority until the ordinary drain's sequence-bound post-handling acknowledgement consumes it.

+**Reconcile sources**
 
 Discovery is never a timer.
-Each registered source has its own child process blocking on that source, and the watcher's per-cycle `reconcile` republishes every captured result with no durable handled acknowledgement yet - regardless of any earlier publication - restarts a source whose owner is gone, and stops this home's runner when reconciliation runs after its registration disappeared unexpectedly.

+**Suppress only adapter-confirmed no-op results**
+
 Whether a captured result is a routine no-op is adapter knowledge too, and the runner names no adapter-specific condition for it either.
-Before publishing, the runner asks the immutable captured owner through the built-in `silent` command or external `result.silent` operation and treats exit 0 as the only silence verdict: the result is recorded as durably handled and never announced, so it neither wakes a handler now nor returns on a later reconcile.
-The task-owned terminal exception is evaluated first, so an empty terminal board round goes to its owner's steering inbox for the required conclusion instead of entering this generic silence path.
-A missing command, an error, any other exit, or a silence the runner cannot durably record all publish the `check` wake exactly as before, so an adapter with no notion of a no-op needs no change and an unknown or degraded result always reaches its handler.
-For built-ins, silence remains independent of the keyed-answer feed below: suppressing an announcement never suppresses the captain's own answer.
-For Lavish that verdict covers two shapes - a session the adapter classifies `ended` that carries no queued content block at all, which is a review surface closed with nothing said, and `browser_disconnected` (classified `disconnected`), which carries no answer while the session remains open.
-Any recognized top-level `prompts` or `feedback` block counts as content regardless of its declared count, and a malformed header makes the result indeterminate rather than empty.
-A `Send & End` close carrying the captain's answer arrives as `status: feedback` with `session_ended`, so it classifies `feedback` and is announced unchanged, as is any `ended` result that still carries content, and every `waiting`, `missing`, `unknown`, or unreadable result.

+
+**Retire terminal sources**
 
 Whether a captured result ends its source is adapter knowledge, never the runner's.
-After capture - and after initial `check` publication for the default ordering - the runner asks the immutable captured owner through the built-in `terminal` command or external `result.terminal` operation and retires the registration on exit 0 alone - except a task-owned board, whose terminal retirement is refused until its owner acknowledges the round, as the crew-hosted section above defines - dropping only the exact registration generation captured by its claim and releasing that claim only after removal succeeds under one source boundary; a missing command, an error, or any other exit keeps the source armed, so an adapter with no notion of ending needs no change.
-A failed terminal removal stays durably terminal and is completed by ordinary reconciliation without restarting its poll, while a concurrently replaced registration survives and becomes independently runnable after the old claim releases.
-Any registration refuses to replace an external registration while its prior runner claim is live, uncertain, orphaned, or terminal-pending; replacement becomes eligible only after that generation is proved gone or its terminal retirement completes.
-A source that has ended therefore captures at most one terminal result, is never restarted, and leaves no recurring poll work.
-For ordinary sources, explicit `retire` stays the supported and idempotent path afterwards; a task-owned board instead refuses `retire` until its owner concludes the open terminal round with `handled`.
-For Lavish that verdict covers an ended session, a missing session, and the final feedback of a `Send & End` review, which the published poll marks with `session_ended` before it returns only empty ended sessions.
+After capture, the runner asks the immutable captured owner whether the result is terminal.
+It uses the built-in `terminal` command or external `result.terminal` operation.
+Under the default ordering, this happens after the initial `check` publication.
+
+- Exit 0 retires the registration.
+  The exception is a task-owned board, whose owner must first acknowledge the round as defined above.
+- Retirement drops only the exact registration generation captured by the claim.
+  Under one source boundary, it releases that claim only after removal succeeds.
+- A missing command, an error, or any other exit keeps the source armed.
+  An adapter with no notion of ending needs no change.

+- For Lavish that verdict covers an ended session, a missing session, and the final feedback of a `Send & End` review, which the published poll marks with `session_ended` before it returns only empty ended sessions.
+
+**Apply built-in results automatically**
 
 Applying a captured result through code is a built-in adapter seam, and some built-in results carry no judgement at all: they must simply be applied idempotently to this home's own durable state.
 Leaving that to a handler means it can silently not happen, so immediately after the terminal check above the runner calls `bin/fm-procevent-<adapter>.sh autohandle <source-id> <sequence> <result-file>` and lets the built-in adapter apply and acknowledge its own result.

 That call runs strictly after terminal retirement, because a handling adapter re-arms its own next source and retiring afterwards would drop that fresh registration and leave the source silently dead.
 Exit 0 means the adapter fully applied and acknowledged the result; a missing command, an error, or any other exit is not a capture failure but leaves the result unacknowledged and therefore still eligible for re-announcement, so a handler receives it exactly as before and an adapter with no such command needs no change.
-Announcement ordering is adapter-declared through `bin/fm-procevent-<adapter>.sh self-announcing`: an adapter that answers exit 0 declares that every result its autohandle fully applies is announced through a durable downstream channel of its own, so the runner applies first and publishes a `check` wake only for what remains unhandled afterwards; every other adapter keeps the strict publish-before-apply order, and its autohandle runs only when this capture's own wake was successfully appended to the durable queue.
+
+**Adapter-controlled announcement order**
+
+The built-in `bin/fm-procevent-<adapter>.sh self-announcing` command declares announcement order:
+
+| Response | Runner behavior |
+| --- | --- |
+| Exit 0 | The adapter declares that every result its autohandle fully applies is announced through its own durable downstream channel; the runner applies first, then publishes a `check` wake only for results still unhandled. |
+| Any other response | Keep strict publish-before-apply ordering; autohandle runs only after this capture's own wake was successfully appended to the durable queue. |
+
 The remote-secondmate reply adapter declares itself self-announcing: a captured reply reaches its local status mirror and settles its correlated pending-reply expectation without any handler step, the mirrored status bytes are the single wake for one remote note through the same signal classification a local secondmate's append gets, and only a capture the adapter could not fully apply is published as a `check` wake, whose adapter handling remains idempotent.
 The [remote-secondmate channel contract](remote-secondmates.md#normal-operation) owns replay suppression and its bounded upgrade exception; a replay that adds no mirror bytes stays quiet.
 
+**Feed keyed captain answers**
+
 Keyed captain answers from built-in adapters use one more seam of the same kind, and the runner still decides nothing about them.
 Some built-in sources carry the captain's answer to a captain-held task, and what such an answer means is owned once by `bin/fm-captain-hold.sh`'s keyed-answer intake rather than by any channel.
-A built-in source bound with `bin/fm-captain-hold.sh bind` therefore has each captured result passed to `bin/fm-procevent-<adapter>.sh answers <result-file>`, and whatever that prints is piped straight into that intake.
-A binding can select one decision origin or the script's cross-origin mode; the command header owns the exact forms and key interpretation.
-The built-in adapter reports only what the captain chose; the intake owns every rule about what happens next, so the runner names no adapter, parses no result, and carries no decision rule, and a future built-in answer source needs nothing here beyond an `answers` command and a binding.
-The reserved Reconcile selection uses the parallel optional `reconciles` adapter command and binding-verified `reconcile-requests` intake rather than entering keyed answers; [`captain-hold-lifecycle.md`](captain-hold-lifecycle.md#reconcile-re-check-reality-never-a-blind-close) owns those semantics.
-Feeding is independent of handling: it never acknowledges a result and never suppresses a wake, because recording the answer or request is transcription while acting on it is firstmate's judgement.
-An unbound built-in source, a built-in adapter without the corresponding command, and a failure on either side all leave the capture untouched and still announced.
-External binding responses never enter either authority-bearing intake.

+
+**Machine-wide source ownership**
 
 Ownership is machine-wide per canonical source, because separate homes can share one underlying source store.
-Claims live under `$XDG_STATE_HOME/firstmate/procevent-claims` (override with `FM_PROCEVENT_CLAIM_ROOT`).
-Each claim binds its caller-reported home and runner PID to a process identity, unique claim generation, exact registration-file generation, and resolved state-root identity.
-Registration, acquisition, replacement, retirement, and generation-bound release are serialized at one machine-wide boundary per source.
-A live identity-matched owner is never displaced, and release removes only the exact generation the caller acquired.
-Every stop proves ownership before its first signal: the live runner's recorded process identity must match and it must still lead its process group.
-Once that stop has proved ownership and sent TERM, its own escalation to KILL checks only whether the proved group still has members; it does not re-read the leader's identity or group membership, which can change or become unreadable as TERM ends the leader.
-This proof belongs only to that stop's own escalation and cannot authorize another caller that encounters an unproved group.

+- Once that stop has proved ownership and sent TERM, its own escalation to KILL checks only whether the proved group still has members; it does not re-read the leader's identity or group membership, which can change or become unreadable as TERM ends the leader.
+- This proof belongs only to that stop's own escalation and cannot authorize another caller that encounters an unproved group.
+
+**Recover orphaned claims**
+
 A stale claim whose process group still has members is one `reconcile` never displaces, and the two shapes it comes in recover differently.
 `reconcile` preserves such a claim without signalling the ambiguous group or starting a replacement: the group check probes the runner's own process group, which contains its polling source child, so surviving members can mean that child is still attached to the session the source collects from, and a replacement would put a second destructive poller on it.
+
 `list` reports both shapes as `orphaned`.
-When the recorded pid is alive under a different identity while the group still has members, the claim boundary itself does not consult the process group, so `bin/fm-procevent.sh start <source-id>` reclaims that claim provided the dead generation's reservation records can still be tidied, and otherwise refuses with `cannot claim source`; that tidy-up is waived only for a generation proven gone, which this one is not.
+
+**Reused PID with surviving group members**
+
+When the recorded pid is alive under a different identity but the group still has members, the claim boundary itself does not consult the process group.
+In this case, `bin/fm-procevent.sh start <source-id>` reclaims the claim only if it can tidy the dead generation's reservation records.
+Otherwise it refuses with `cannot claim source`.
+
+Tidy-up is waived only for a generation proved gone.
+This generation does not meet that condition.
 That hand-run command is the recovery path, taken by someone who has checked that nothing is still polling the source.
+
 That asymmetry between the automatic path and the deliberate one is the design rather than an inconsistency, and it is not a claim-level invariant: nothing below `reconcile` enforces it.
-When the leader itself is gone and its group still has members - the leader died to anything other than the stop's own signal - `start` does not reclaim the claim either: it reports `already owned` and changes nothing, and `retire`, `reconcile`, `sweep-home`, and the guard all refuse the surviving group permanently, so the source stops listening.
+
+**Dead leader with surviving group members**
+
+If the leader died from anything other than the stop's own signal and its group still has members, `start` does not reclaim the claim.
+It reports `already owned` and changes nothing.
+
+`retire`, `reconcile`, `sweep-home`, and the guard all refuse the surviving group permanently, so the source stops listening.
 Recovery there is a human verifying whether the dead runner's polling child is still attached to the source; once that process group is empty the generation reads as gone and the next `reconcile` reclaims the source on its own.
+
 Nothing automatic signals that group, and whether it may ever be signalled remains an open decision; the repaired guard does not close this gap.
-Neither shape stops listening quietly: the first `reconcile` that strands a claim generation publishes a durable `check` wake naming the source and what clears it - the `start` command for the reused pid, the check to make for the leaderless group - and later cycles stay silent for that same generation while a genuinely new stranded claim announces again.
+
+**Report stranded claims**
+
+The first `reconcile` that strands either kind of claim generation publishes a durable `check` wake.
+It names the source and the recovery step:
+
+- For a reused pid, the `start` command.
+- For a leaderless group, the check to make.
+
+Later cycles stay silent for the same generation.
+A genuinely new stranded claim announces again.
+
+**Reclaim a generation proved gone**
+
 Reclaiming a generation that IS gone is not gated on tidying anything that generation left behind: its capture-reservation records, its staging file, or the registry directory a claim recorded for them.
 Every one of those is keyed by claim token and every replacement claims a fresh one, so a leftover that can no longer be located or removed - a state-root identity a claim recorded before its home was re-created, or a recorded registry directory that no longer resolves to a directory - is stale bytes rather than an ownership hazard.
+
 Making any of them a precondition is what leaves a provably dead runner owning its source permanently, because none of those conditions clears on its own.
-Ordinary release and reclamation still attempt reservation cleanup and require it unless both owner staleness and whole-group absence prove the generation gone.
-The narrow live-owner terminal-self-retirement path also attempts cleanup but tolerates its own still-in-flight reservation, which the runner removes on the normal end-of-capture path; exact home, PID, and claim-token ownership remains mandatory before the claim is released.
-If identity cannot be established before the first signal, or a surviving owned group cannot be proved stopped, the operation preserves the registration and claim for safe retry rather than adding a second owner.
-A live PID whose identity no longer matches is refused before the first signal.
-Identity and process-group verification cannot be made atomic with signalling in portable shell: the reaper signals only a target it has verified as the recorded generation, but PID and group reuse remain possible in the narrow interval between verification and the signal.
-Launch pacing is the primary host-wedge protection; watchdog cleanup is a backstop.
-
-Supported secondmate retirement preflights each target home's bounded `sweep-home` command before destructive teardown, snapshots its registrations outside the target, then runs the sweep at that home's final deletion or return boundary.
-If deletion or return fails, teardown restores those registrations and reconciles them before returning the refusal.
-If restoration or rearming also fails, teardown returns a distinct status and reports the retained registration backup path for manual recovery instead of hiding the retired waits.
-The sweep retires local registrations and machine-wide claims whose recorded state-root identity matches that home's resolved state root through the same identity-checked, generation-bound retirement path, and leaves foreign-home claims untouched.
-Teardown refuses with the home, lease, routing evidence, registrations, claims, and runners retained when identity is uncertain, ownership is unreadable or unreleased, or relevant state exists without a sweep-capable child script.

+- Teardown refuses with the home, lease, routing evidence, registrations, claims, and runners retained when identity is uncertain, ownership is unreadable or unreleased, or relevant state exists without a sweep-capable child script.
+
+**Recover from unsupported manual deletion**
+
 Raw manual deletion of a Firstmate home is unsupported because it can orphan a blocking child.
 To recover, restore that home's tracked `bin/fm-procevent.sh`, run `FM_HOME=<home> <home>/bin/fm-procevent.sh sweep-home`, then rerun the supported teardown.
+
 The owning-home lease below bounds how long such an orphan can run, but it is a backstop, not a substitute for the supported path.
 
+**Home lease and its limits**
+
 A runner is bound to the HOME that owns it, not to the one session that armed it.
 That granularity is deliberate: a persistent source is meant to outlive the turn and the session that armed it, so binding a runner to its arming session would stop exactly the sources this mechanism exists to keep running.
+
 Any activity in the same home refreshes the lease, so a replacement session, another watcher, or an ordinary inspection command keeps a runner of that home alive; a runner whose SOURCE is no longer wanted in a live home is stopped by reconcile when that source is retired, independently of the lease.
 The lease is therefore the backstop for a home that is GONE - the torn-down test sandbox this change exists to bound - and not a per-session ownership check.
+
 KNOWN LIMIT: while any activity continues in a home whose original owning session has ended, that activity refreshes the lease and a runner of that home keeps running until its source is retired or the home goes away.
+
+**Keep and guard the lease**
+
 Detaching a runner into its own process group is what lets a persistent source outlive the turn that armed it, and on its own it is also what lets a runner outlive its whole home: reparented to init, it keeps its blocking child - and every process that child spawns - running with nothing left to reap it.
-So a home's process-event state carries a lease that registration, attached start, reconciliation, acknowledgement, and listing refresh, and the watcher's reconcile cycle is what keeps it fresh in a live home.
-An attached public `start` continues refreshing the lease while its caller remains attached.
-Each runner fails closed unless a small guard starts successfully beside it in a separate process group.
-That guard accepts the lease only while the state root retains the device/inode identity recorded by the runner's claim, and initiates the verified stop after two consecutive reads cannot prove that identity and lease freshness, so one unreadable read cannot kill a live runner.
-Those two reads are spaced half a check interval apart, so the pair the debounce requires completes inside one check interval instead of costing two of them.
-For a runner whose ownership can still be proved, the nominal detection bound is therefore the lease plus one check interval, after which the verified stop runs within its own grace period; the lease age is compared in whole seconds, so a configured lease is honoured until that age reads one second past it, and scheduling delays or failed inspection and signalling can extend the whole bound.

+The verified stop then runs within its own grace period.
+The lease age is compared in whole seconds, so the configured lease is honoured until that age reads one second past it.
+
+Scheduling delays or failed inspection and signalling can extend the whole bound.
 That grace is a ceiling rather than a delay every stop pays: two seconds for the ordinary signal and two more for the forced one, spent only by a group that outlives the signal it was sent, which is why a healthy runner's stop completes in a fraction of a second.
+
 The group signal reaches the blocking child and everything under it exactly as retirement does.
-A runner exports the inherited `FM_PROCEVENT_IN_RUNNER` marker and every lease refresh is skipped under it, so a runner and its ordinary children do not certify their own owner, and the next reconcile in a live home simply starts a replacement runner.
-That no-self-refresh rule is CONFUSED-AGENT-GRADE, the same deliberate captain-decided grade `bin/fm-lease-lib.sh` documents: it stops the accidental case this boundary exists for, an orphaned or test-scaffolding source tree that would otherwise keep its own owner alive.
-A source that DELIBERATELY strips the marker from its environment can still refresh the lease, so adversarial-grade unforgeability is explicitly out of scope here and tracked as separate follow-up design work.
-Scope is the owning state root and one runner generation, never a script or process name, so a live source in another home is untouched: that home refreshes its own lease.
-`FM_PROCEVENT_OWNER_LEASE_SECONDS` (default 600, range 1..86400) is how long a runner keeps going with no sign of activity in its owning home, and `FM_PROCEVENT_OWNER_CHECK_SECONDS` (default 15, range 1..3600) is the guard's detection interval: it re-reads the lease and the recorded state-root identity twice within each interval, half an interval apart, so the two reads its debounce needs fit inside one interval rather than costing two.
-`FM_PROCEVENT_LAUNCH_FLOOR_SECONDS` (default 1, range 1..3600) is the minimum time between consecutive launches of one registration generation's stored command, bounding the launch rate of an immediately returning source during that lease window.

+**Lease and launch pacing settings**
+
+| Setting | Default | Range | Purpose |
+| --- | --- | --- | --- |
+| `FM_PROCEVENT_OWNER_LEASE_SECONDS` | 600 | 1..86400 | How long a runner continues without activity in its owning home. |
+| `FM_PROCEVENT_OWNER_CHECK_SECONDS` | 15 | 1..3600 | Guard detection interval; it reads the lease and recorded state-root identity twice per interval, half an interval apart, so both debounce reads fit inside one interval. |
+| `FM_PROCEVENT_LAUNCH_FLOOR_SECONDS` | 1 | 1..3600 | Minimum time between consecutive launches of one registration generation's stored command; bounds immediately returning sources during the lease window. |
+
 The generation's first launch is immediate, later launches share its monotonic pacing timestamp, a timestamp from before a reboot is treated as expired, and replacing the registration starts a fresh pacing generation.
 
+**Confirm detached launches**
+
 `FM_PROCEVENT_LAUNCH_CONFIRM_SECONDS` (default 3, range 1..600) bounds how long `reconcile` waits for the runners it just started to prove they are running: never less than the configured value, and at most one second more, because the wait is measured on a whole-second clock.
-Starting a runner is detached and its errors are not visible to the caller, so `reconcile` reports a start only after the source is observed owned or its launch-pacing stamp has advanced or appeared, and reports every unconfirmed launch as `failed=` and a non-zero exit instead.
-Both signals are durable evidence a runner claimed: ownership is the only evidence a runner still blocked on its source ever shows, and the stamp - written after the claim and before the source command runs, and removed only by registration replacement - covers a runner that claimed, ran and exited between two polls.
-A healthy launch therefore confirms on the first poll and the window only bounds a launch that has not yet proved itself - one that died before claiming, or one merely too slow to claim inside the window; confirmation cannot tell those apart, and a launch that proves itself on a later cycle closes its failure episode without a retraction wake.
-All of a cycle's launches share one window, so a home full of sources that cannot start costs the same bounded wait as one.

+- All of a cycle's launches share one window, so a home full of sources that cannot start costs the same bounded wait as one.
+
+**Keep confirmation below the watcher interval**
 
 Keep this window well below `FM_POLL`.
 `bin/fm-watch.sh` runs `reconcile` once per supervision cycle, so a source that cannot start makes every cycle wait up to the confirm window before the rest of that cycle runs.
+
 Raising the confirm window lengthens every supervision cycle and delays wake delivery by up to that much.
 
+**Report launch failures**
+
 A source that can never start is reported as `failed=` with a non-zero exit on every `reconcile`, rather than counted as `started` and retried silently as though it were healthy, so a wedged source stays visible instead of presenting as armed.
-That count reaches only whoever runs the command, because `bin/fm-watch.sh` discards `reconcile`'s output and exit status, so an unconfirmed launch is also announced through the wake queue: `reconcile` publishes a durable `check` wake (`procevent:<id>:launch-failed:<registration-identity>-<episode-nonce>`) once per failure episode, and later cycles stay silent for that episode until a launch of that source confirms, after which a fresh failure announces again under a fresh key, because the watcher never re-surfaces a key it has already surfaced.
-The announcement changes nothing about the launch: `reconcile` keeps relaunching the source every cycle exactly as before, and nothing is retried differently, throttled, or recovered from that signal.
-The wake says only what was observed for that shape - the launch did not prove it took the claim within the window - and, if it stays that way, names the source command and adapter binary the registration names as what to check and the attached `bin/fm-procevent.sh start <source-id>` as what reproduces a refusal on stderr, where the detached launch discards it; a later cycle that finds the source owned ends the episode on its own, so a runner that was merely slow to claim needs nothing from the operator.
-A source stranded on a claim nothing may automatically displace is announced the same way, once per stranded claim generation, as described above.
-`bin/fm-watch.sh` surfaces both under their own headlines - `process-event source stranded` and `process-event source failed to start` - rather than as a captured result.
+The `failed=` count reaches only the command's caller because `bin/fm-watch.sh` discards `reconcile` output and exit status.
+For that reason, `reconcile` also publishes a durable `check` wake once per failure episode, with key `procevent:<id>:launch-failed:<registration-identity>-<episode-nonce>`.
+Later cycles stay silent for that episode until a launch confirms.
+A later fresh failure gets a fresh key, because the watcher never re-surfaces a key it has already surfaced.
+
+- The announcement changes nothing about the launch: `reconcile` keeps relaunching the source every cycle exactly as before, and nothing is retried differently, throttled, or recovered from that signal.

+  The detached launch discards that output.
+- A later cycle that finds the source owned ends the episode automatically.
+  A runner that was merely slow to claim needs no operator action.
+- A source stranded on a claim nothing may automatically displace is announced the same way, once per stranded claim generation, as described above.
+- `bin/fm-watch.sh` surfaces both under their own headlines - `process-event source stranded` and `process-event source failed to start` - rather than as a captured result.
+
+**Reject unusable settings**
 
 A value this command cannot use is refused by name before anything is launched, the same way `FM_PROCEVENT_LAUNCH_FLOOR_SECONDS` and `FM_PROCEVENT_MAX_OUTPUT_BYTES` are refused, so a mistyped window can never present as a fleet of sources that cannot start.
 `bin/fm-watch.sh` validates the same value when it arms and refuses to arm on an unusable one, naming the variable and the range: under a running watcher that refusal would otherwise repeat on every cycle into a discarded stdout and leave the whole home disarmed while presenting as supervised, whereas a watcher that will not arm is loud through the liveness guard.
 
+**Limit captured output**
+
 `FM_PROCEVENT_MAX_OUTPUT_BYTES` (default 1048576) bounds a single captured result while the source runs; oversized output is drained but truncated with a stderr notice rather than staged or published whole or dropped.
 
+**Durability guarantees and limits**
+
 The runner proves exactly one durability boundary: output that reached the runner is stored at mode `0600` before any event referencing it is published, and a captured result with no durable handled acknowledgement remains eligible for bounded re-announcement across any number of drains and restarts, not only the crash window right after capture.
-`bin/fm-procevent.sh handled <source-id> <sequence>` is the only thing that stops re-announcement: a generation-keyed, private, path-safe, durable, and idempotent acknowledgement that atomically checks and deduplicates by the exact source and sequence, so a paired effect gated on its first-time-vs-repeat report is never authorized twice.
-Default and fallback `check` publication is still best-effort, so the same source and sequence can repeat even before any restart; handlers deduplicate that identity rather than assuming a wake is unique.
-The runner proves nothing about the source side, and the handled acknowledgement proves nothing about a paired external effect performed before it: a crash between that effect and the acknowledgement call can still repeat the effect on replay, so this is never a generic exactly-once guarantee.
-The published `lavish-axi poll` clears feedback destructively before returning it, so a result lost between that clearing and the runner reading process output is unrecoverable.
-Never describe this path as at-least-once, no-loss, or lossless.

 ## Spoken interface and captain inbox (config/voice-*, config/inbox-*)
 
 The spoken interface in [`docs/voice-relay.md`](voice-relay.md) and the model-backed subcommands of `bin/fm-inbox.sh` reach a paid API in a named account, so no region, model id or AWS profile is shipped as a tracked default.
 Each is one line in a local, gitignored `config/` file, with an environment variable that overrides it for a single run, and a missing required value refuses with the path to write rather than falling back to a value that belongs to another home.
+
 That configuration is the whole opt-in: an unconfigured home cannot start the relay and cannot run `fm-inbox.sh say` or `ask`, while `note`, `announce`, `reply`, `receipts`, `ready`, `status`, `list` and `drain` need no configuration at all because they make no model call.

-The two read files are parsed differently: `config/voice-read-scope` must hold the bare word and nothing but blank space around it, so a comment header there refuses instead of being skipped, while every line of `config/voice-read-deny` that is not blank and not a `#` comment is one more substring.

+- `config/voice-read-scope` must contain only the bare word with optional blank space around it.

 A live lock, a missing `lsof`, any failed check, or any other fetch failure keeps today's behavior.

Subject: [PATCH 06/84] fix: limit project memory edits to factual corrections
 (#5636)

* fix: bound worker edits of project AGENTS.md/CLAUDE.md to factual corrections

These files are loaded into every agent session of a project, so additions
should be a deliberate human choice rather than automated task output. The
ship brief's project-memory section and AGENTS.md section 6 previously invited
workers to record durable knowledge, which let project AGENTS.md files accrete
detail the codebase or README already carries. Workers now edit only to fix
factually wrong content - including content their own change made wrong - and
fm-ensure-agents-md.sh runs only alongside such a correction. Stow no longer
routes project-memory additions through ship tasks, and the generated skeleton
no longer invites discovery-driven additions.

* no-mistakes(review): Stop running fm-ensure-agents-md.sh on memory-file corrections

* no-mistakes(document): Clarify manual project-memory initialization and remove duplicate guidance

 ## Project memory belongs to projects
 
-Durable project-intrinsic agent knowledge lives in each project's committed `AGENTS.md`, with `CLAUDE.md` as a real `@AGENTS.md` import pointer.
-Ship briefs prompt crewmates to create or update those files through the normal delivery path; `data/projects.md` stays a thin private registry.
-Each project `AGENTS.md` carries self-governance guidance; [`bin/fm-ensure-agents-md.sh`](../bin/fm-ensure-agents-md.sh) owns the canonical wording and idempotent insertion, while its header and help document the explicit mark for equivalent project-owned guidance.
-It refuses a case-variant real memory file such as a lowercase `agents.md`, so the pointer's `@AGENTS.md` import resolves to a real `AGENTS.md` on a case-sensitive filesystem, and surfaces the mismatch for manual reconciliation.
-The full ownership rule - what is project-intrinsic versus fleet-private, and how firstmate keeps the two apart without writing into project clones - is owned by [`AGENTS.md`](../AGENTS.md) (project and knowledge management).
+Project-memory ownership and the crewmate corrections-only boundary are defined in [`AGENTS.md` section 6](../AGENTS.md#6-project-and-knowledge-management); `data/projects.md` stays a thin private registry.
+For manual project initialization, [`bin/fm-ensure-agents-md.sh`](../bin/fm-ensure-agents-md.sh) owns the `CLAUDE.md` pointer, self-governance insertion, and case-variant file refusal; its header and help document the explicit mark for equivalent project-owned guidance.
 
 ## Operational memory routing
 
 `/stow` sweeps the current session for durable knowledge that only exists in conversation and routes each finding to the most specific disk home.
-Home-domain captain preferences go to `data/captain.md`, cross-domain shared captain preferences go to the primary home's `data/captain-shared.md`, fleet-local operational facts and gotchas go to home-local `data/learnings.md`, project-intrinsic knowledge goes through normal crewmate delivery into that project's committed `AGENTS.md`, and task-scoped notes or undone next steps go to the backlog.
+The destination for each kind of knowledge, including project-intrinsic knowledge, is owned by [`AGENTS.md` section 6](../AGENTS.md#6-project-and-knowledge-management).
 Memory writes use inspect-then-update rather than blind append; the internal [`stow` skill](../.agents/skills/stow/SKILL.md) owns tier markers, decay, cold archival, and offload.
 The same pass also persists open-work record state the session is holding - filing a thread that was never recorded and correcting one the session knows went stale - bounded to the open work that session is actually holding.
 It is deliberately not a reconciliation of durable records against repository or PR reality: its input is the volatile context, so it can only preserve what the session still knows, and no reconciliation that outlives a session exists today.

Subject: [PATCH 07/84] feat: permit gate lifecycle calls against disposable
 lab homes (#5635)

* fix(bin): let gate agents drive lifecycle against marked lab homes

Part 2 of the #5615 split. A no-mistakes gate agent runs inside a
checkout carrying the fleet-captain identity, so fm-gate-refuse-lib
refuses fleet mutation on the gate signal. That refusal was absolute,
which kept gate validation from ever exercising the real lifecycle.

Stamp a disposable lab FM_HOME with a .fm-lab-home marker file that
only bin/fm-lab-home.sh writes, and only onto a fresh empty dir, so
no call path can mark a populated real home. fm_refuse_if_gate_agent
then permits lifecycle only when FM_HOME carries the marker and is
driven through its stock layout - any FM_*_OVERRIDE relocation stays
refused so part of the "lab" cannot be split back onto the real fleet.
The threat model is a confused agent touching the real fleet, not
deliberate forgery, so the marker is a plain token file rather than a
bound record. FM_GATE_REFUSE_BYPASS is unchanged: it still serves the
test harness, which cannot mark hundreds of temp homes.

Teardown's slot-ownership scan compared state-dir paths textually
while fm_firstmate_root_home canonicalizes, so a lab home under a
symlinked TMPDIR scanned its own record twice and self-collided;
compare file identity (-ef) instead.

* no-mistakes(review): Refuse unlistable lab homes and hardlinked slot records

* no-mistakes(review): Mint lab markers only on verified-empty fresh dirs

* no-mistakes(document): Clarify lab-home gate documentation and comment contracts

* no-mistakes(document): Clarify lab-home gate documentation and remove stale claims

* no-mistakes(document): Clarify gate lab-home documentation and boundary wording

 Firstmate's own no-mistakes gate runs agents inside a checkout that also contains the fleet-captain identity in `AGENTS.md`, so gate execution needs an authority boundary separate from ordinary crewmate worktree isolation.
 The tracked `.no-mistakes.yaml` sets `disable_project_settings: true`; no-mistakes honors that setting only from the trusted default-branch copy, so a pushed branch cannot enable its own project instructions during validation.

Subject: [PATCH 08/84] fix(bin): evict a watcher whose beacon stalls past a
 hard bound instead of refusing every re-arm (#5594)

* fix(bin): replace a watcher whose beacon stalls past a hard bound instead of refusing every re-arm

A fleet watcher that is alive but whose liveness beacon has gone stale could
never be replaced: every re-arm was refused because the lock holder was a live
pid, and the holder was never evicted because it was not dead. Add
FM_WATCHER_STALL_BOUND (default 3x the stale grace): below it the refusal is
unchanged; at or past it the arm re-verifies the holder against the lock's
recorded identity, sends TERM, waits boundedly, and takes the lock the normal
way, ledgering a stalled-holder-replaced row. A holder that survives TERM keeps
the old refusal.

Fixes #4400

* no-mistakes(test): poll for replacement message to fix watcher-lock test flake

* no-mistakes(document): document FM_WATCHER_STALL_BOUND in config inventory

 A fixed 300-second grace default stops correctly bounding staleness once a home's `FM_POLL` reaches or exceeds it: a perfectly healthy watcher mid-wait would then read stale at the edge of every full poll cycle by definition, which is exactly what a long-poll home (`FM_POLL=300`) hit against the Claude Stop-hook auto-arm (`bin/fm-claude-stop-autoarm.sh`).
 That hook and `bin/fm-watch.sh`'s own pre-acquisition staleness check (the "lock held by live pid but heartbeat is stale" refusal) both derive their default grace from the configured poll instead of a bare constant: `max(300, FM_POLL + 60)`, so the default never drops below the historical 300-second floor for the common short-poll case but grows with the poll cadence once that cadence would otherwise outrun it.
 `fm_poll_derived_grace` in `bin/fm-wake-lib.sh` is the single owner of that formula.
+That refusal has a ceiling: once the live holder's beacon is stale past `FM_WATCHER_STALL_BOUND` (default three times the grace), the re-arm re-verifies the holder against the lock's recorded identity, retires it with TERM, and starts in its place, so a watcher wedged mid-cycle can no longer refuse every replacement indefinitely; `bin/fm-watch.sh`'s header owns the exact wording and the survives-TERM fallback.
 The auto-arm hook additionally exports its resolved `FM_GUARD_GRACE` when it forks `bin/fm-watch-arm.sh`, so the arm wrapper and the watcher it may start judge staleness with the exact same value the hook just judged it with, whether that value came from an operator override or the poll-derived default.
 `bin/fm-turnend-guard.sh`'s daemon-ownership branch (`fm_afk_daemon_owns_supervision`, above, covering both away and quiet mode) also derives its beacon grace from `fm_poll_derived_grace` rather than falling back to the bare 300-second default, for the same reason: the daemon's watcher-restart cadence there is not a fixed poll loop, so a flat grace misreads a daemon that is genuinely still cycling as down.
 Every other direct `FM_GUARD_GRACE` reader (`bin/fm-guard.sh`, the strict-watcher checks in `bin/fm-turnend-guard.sh` and its harness-specific wrappers, `bin/fm-wake-lib.sh`) still falls back to the bare 300-second default unless `FM_GUARD_GRACE` is set explicitly in the environment.

Subject: [PATCH 09/84] fix(pi): hide queued Firstmate inputs under Calm only
 when the session can keep them (#5563)

* fix(pi): hide queued Firstmate notifications under Calm only when the session can keep them

Calm now keeps authenticated Firstmate operational inputs out of Pi's queued-message
listing, but only after proving the live session exposes every member needed to keep
them across Escape. A session missing any of them keeps stock rows and Escape and shows
one generic warning. Escape and the dequeue key return only captain-authored messages to
the editor and re-queue hidden notifications in order; after an abort that kept any in
Pi's agent queue, the adapter starts the delivery turn itself because Pi 0.87.1 does not
continue an aborted run. Compaction-held notifications stay with Pi's compaction flush and
never start or announce a turn.

Fixes #1588

* docs(calm): record Pi 0.87.1 queued-row retention verification

* no-mistakes(review): Deliver kept Calm notifications after tree-navigation aborts too

* no-mistakes(review): Defer Calm notification turn until tree navigation finishes

* no-mistakes(lint): Silence SC2016 for literal JavaScript in queue-retention e2e test

+// clean. Under Calm the restore hands only the other messages to the editor and puts the

+## Queued operational-row retention
+
+On Pi 0.87.1 with Calm persisted on, a Firstmate watcher notification sent while a tool held the turn was listed under the running turn as `Follow-up: FIRSTMATE_OP: v1 watcher: ...`, identical to Calm off.
+Pressing Escape moved that raw text into the editor and removed it from Pi's queue, and the session recorded no delivery of it, so a captain who cleared the editor lost the notification.
+The initiating trigger was a notification queued during a run.
+The exposure condition was that Pi draws queued input in `InteractiveMode.updatePendingMessagesDisplay` and restores it through `restoreQueuedMessagesToEditor`, a path separate from the `addMessageToChat` path the operational-user adapter covers.
+The visible symptom was the listed row and, after Escape, the raw text in the editor.
+
+Hiding the listed row alone would turn the Escape path into the defect issue #1588 describes: stock restore joins the whole queue into the editor, so a hidden notification would reappear as raw text.
+Keeping it queued across the restore needs the session's already-expanded queueing entry points (`_queueSteer` and `_queueFollowUp`) and, for the delivery below, `clearQueue`, `waitForIdle`, `sendUserMessage`, and `isIdle`.
+Those live on the session instance reached through `InteractiveMode.session`, so they are checked per session before the first row is hidden rather than at extension load.
+
+A counterfactual built from the closed PR #1620 adapter hid the row and kept the notification out of the editor, but Pi 0.87.1's `AgentSession._runAgentPrompt` stops continuing once an abort was requested, so the kept follow-up stayed queued until the captain's next prompt while the adapter announced a new turn.
+The shipped adapter therefore starts that turn itself once the aborted run settles: it takes the first queued message out, sends it with `sendUserMessage`, and puts the rest back behind it in Pi's delivery order.
+Navigating the session tree during a run takes the same path without an abort flag, restoring the queue and then calling `session.abort()`, so the adapter waits for every restore that kept a notification and starts the turn only if the session is then idle with messages still queued.
+Pi starts `navigateTree` in the same microtask run that resumes from that abort and marks the session busy before its first await, so the adapter yields one macrotask after each idle wait and waits again while the session is busy, which starts the turn on the navigated branch instead of racing the navigation on the abandoned one.
+The same real-Pi reproduction then delivered the notification exactly once in a new turn, returned a queued captain message to the editor, and left Calm off stock.

 The operational provider path covers Calm loaded on, loaded off, default preference, extension absent, exact watcher delivery, narrow bare-marker legacy input, persisted restart replay, a genuine captain prompt, and adjacent notifications coalesced into one intended processing turn.
 It asserts one persisted and rendered captain answer, exact user-role operational envelopes in order, no replacement custom messages, one processing result, zero operational transcript rows, and the two-row neighboring-assistant geometry for live, adjacent, and restart paths.
 Quoted current markers, ASCII-only labels, ordinary text before a marker, unrelated U+2063 placement, and image-bearing input remain visible in component and native transcript checks.

 Claude Code 2.1.272 exposes exactly the capability the 2026-07-22 row found missing, through its early-access "Claude Mods" surface, whose engineering primitive is the function hook: a plugin whose behavior lives in one hooks module exporting `register(on, options)`, hooking dotted engine events as `($, e, next)` middleware, with `ui.render` drawing per-component transcript rows and the working row, `$.ui.invalidate("ui.render")` redrawing every hooked drawing, and `$.ui.blit` repainting a mounted `Raster` without a render pass.

 The operational inputs Calm classifies remain ordinary user-role messages, while Pi's transcript layout renders their complete rows at zero height.
+While a turn runs, Calm also keeps those Firstmate inputs out of Pi's queued-message listing, and the captain's own queued messages stay listed.
+Escape and the dequeue key return only the captain's queued messages to the editor; hidden Firstmate inputs stay queued in their original order and are never shown as raw text or dropped.
+When Escape, or navigating the session tree, stops a run with Firstmate inputs still queued, Calm starts one new turn to deliver them and shows the one-line notice `Firstmate supervision continues in a new turn.`
+Inputs held behind a running compaction stay there until Pi sends them after compaction, so they start and announce no turn of their own.

+# Default-on live guard for the capability Calm's queued-row adapter preflights: a real
+# interactive Pi session must expose every session member the adapter uses to keep a hidden
+# queued notification across Escape. Those members live on Pi's session object, not on an
+# exported class, so only a running Pi can answer.
+#
+# When a member is missing, the adapter degrades quietly by design: queued Firstmate rows
+# stay visible and one warning appears. This guard fails loudly naming the installed Pi
+# version instead, so a Pi release that removes the capability is noticed rather than
+# silently costing the captain the hidden rows. The Escape flow itself is pinned by
+# test_queued_operational_rows and test_queued_operational_escape_e2e in
+# tests/fm-calm-pi-extension.test.sh.
+#
+# No model turn reaches any provider: a local faux provider holds one turn in a tool so a
+# message can queue, and a probe extension records the live session's members from Pi's
+# own queued-listing redraw. Scratch FM_HOME, project, Pi agent directory, session

Subject: [PATCH 10/84] fix(bin): refuse teardown when a required source
 disappears (#5548)

* fix(bin): refuse teardown when a required source disappears

A missing sibling was sourced after cleanup had started, so Bash 3.2
exited 0 from the EXIT trap and Bash 5 continued and reported success.

* no-mistakes(review): Remove unused FM_TEST_ONLY hook from teardown tests

* no-mistakes(review): Check task backend sources before any teardown cleanup

* test(gotmp): give teardown fixtures every tmux adapter sibling

Teardown now refuses when a sibling the recorded backend's adapter sources
is missing, so the fake bin must carry fm-session-lock-lib.sh,
fm-agent-process-lib.sh and fm-gemini-lib.sh.

Subject: [PATCH 11/84] docs: make supervision-host easier to read (#5605)

Restructure the supervision host doc's prose into shorter sections, lists,
and tables without changing documented behavior. Every original heading,
anchor, identifier, number, quoted string, and link target is preserved.

 # Supervision host
 
 The supervision host runs the supervision branch's contract beside a primary that is not Pi.
-On Pi the branch is a second conversation inside the captain's own process ([pi-supervision-branch.md](pi-supervision-branch.md)); off Pi no such process exists, so the host owns the watcher cycle for the primary and runs the branch as a headless engine session.
-It is one architecture with Pi's, not a second one: the same branch prompt, the same row eligibility, the same records, and the same guarded scripts decide what the branch may do.
+This doc explains how it does that and which script owns each part, for maintainers changing the host, its engine, or a primary's arm owner.

+Off Pi no such process exists.
+So the host owns the watcher cycle for the primary and runs the branch as a headless engine session.

+These parts are shared with Pi and decide what the branch may do:
+
+- The same branch prompt.
+- The same row eligibility.
+- The same records.
+- The same guarded scripts.
+
+A close is the output a watcher cycle prints when it ends.
+An arm owner is the component in each primary harness that starts watcher cycles and reads their close.
 
 ## Scope today
 
 The host is opt-in per home through `config/supervision-host`; [configuration.md](configuration.md#supervision-host-configsupervision-host) owns the file.
 Without the file every home behaves exactly as it does without the host.
-Today it runs beside a Claude, Cursor, OpenCode, omp, Grok, or Codex primary and only takes wakes in the away posture:
+Today it runs beside a Claude, Cursor, OpenCode, omp, Grok, or Codex primary and only takes wakes in the away posture.
 
-- Attended (no away-posture record `state/.afk-contract`), the host is a pass-through: every close reaches main exactly as the plain watcher arm delivers it.
-- Away (the record exists), the host hands each close to the engine, and main stays parked unless the host hands the wake back.
-- `/afk` launches no away daemon on an opted-in home of those harnesses, because the host is the away session there; `/quiet` still launches the daemon, and while its flag `state/.afk` exists the host stands aside exactly as the plain arm does.
+### Behavior by posture and harness

+- Attended (no away-posture record `state/.afk-contract`), the host is a pass-through.

+  While its flag `state/.afk` exists, the host stands aside exactly as the plain arm does.
 - Pi keeps its in-process branch whether or not the file exists, and no Pi engine is built.
 - Kimi has no primary supervision protocol, so it has no arm owner to run the host.
 
-Attended supervision on the host, `/quiet` on the host, and the daemon's retirement are later steps of the same design; until they land, their current behavior stays as described in their own owners.

 ## Components and their owners
 
-- The loop: `bin/fm-supervision-host.sh`, whose header owns the per-close order, the park boundary, ownership checks, predecessor cleanup, state files, and tunables.
-- The arm owners: each primary's existing arm owner runs the host in place of its watcher command for an opted-in home and delivers a handed-back wake through the wake path that harness already trusts; the host's header owns the output contract they read.
-
-  | Primary | Arm owner | A handed-back wake reaches main as |
-  |---|---|---|
-  | Claude | the Stop auto-arm, `bin/fm-claude-stop-autoarm.sh`, inside its single-flight generation | the hook's exit-2 rewake (`Stop hook feedback`) |
-  | Cursor | the `stop` hook park, `bin/fm-turnend-guard-cursor.sh` | the park's `watcher` follow-up |
-  | OpenCode | the TUI plugin, `.opencode/plugins/fm-primary-watch-arm.js`, which restarts its own successor after each close | a `watcher` prompt through `promptAsync` |
-  | omp | the watch extension, `.omp/extensions/fm-primary-omp-watch.ts`, which restarts its own successor after each close | the extension's `watcher` follow-up |
-  | Grok | the model's tracked background call, rendered as `bin/fm-supervision-host.sh park` at session start | the background task's completion notification |
-  | Codex | the foreground checkpoint, `bin/fm-watch-checkpoint.sh`, in the watcher's place | the checkpoint's own output |
-
-  Hook, plugin, extension, and checkpoint owners pass their harness as the primary pin; Grok's model-owned call relies on primary detection.
-  The host pins dispatched work to the primary's crew harness rather than the engine's.
-  Grok's arm command is fixed when the session-start block renders, so adding or removing the file on a Grok home takes effect at the next session start; the other owners read the file at every arm.
-- The engine: `bin/fm-supervision-engine-lib.sh` owns the opt-in parse, the verified-engine list, and one bounded engine turn, including the reap of engine tool processes that outlive it.
-- Row eligibility: `bin/fm-branch-dispatch.mjs` is the command entry to `.pi/extensions/lib/fm-branch-dispatch.ts`, so the host and the Pi extension compute branch-claimable rows and their task scope from one owner; it also renders the wake message with the same away-posture tail.
-- The grant and the drain: `bin/fm-wake-grant.sh` publishes the branch's rows bound to the host's own process, and [watcher-continuity.md](watcher-continuity.md#per-actor-acknowledgement) owns the per-actor drain and acknowledgement the engine runs.
-- The prompt: `bin/fm-branch-prompt.sh` emits the same byte-stable prompt the Pi branch runs; each wake names its host's report surface.
-- The report surface: `bin/fm-branch-report.sh` is the command twin of the Pi branch's `fm_branch_report` tool, with the same task scoping, and it appends to the outcome store (`bin/fm-branch-outcome.sh`) plus a per-turn receipt the host requires; a row recorded after the captain returned is also queued for main as a durable check wake.
-- Leases and authority: `bin/fm-lease-lib.sh` owns the per-task leases, the main-owned role partition, and the away relocation; the host's engine runs with `FM_SUPERVISION_ACTOR=branch`, the session-lock holder as `FM_LEASE_HOLDER_PID`, and the primary's harness pin, so every guarded script treats it exactly as it treats the Pi branch.
-- The main side: [supervision-protocols/supervision-host.md](supervision-protocols/supervision-host.md) is what main reads at session start on an opted-in home, rendered for its harness.

+
+### Arm owners
+
+For an opted-in home, each primary's existing arm owner runs the host in place of its watcher command.
+The arm owner delivers a handed-back wake through the wake path that harness already trusts.
+The host's header owns the output contract they read.
+
+| Primary | Arm owner | A handed-back wake reaches main as |
+|---|---|---|
+| Claude | the Stop auto-arm, `bin/fm-claude-stop-autoarm.sh`, inside its single-flight generation | the hook's exit-2 rewake (`Stop hook feedback`) |
+| Cursor | the `stop` hook park, `bin/fm-turnend-guard-cursor.sh` | the park's `watcher` follow-up |
+| OpenCode | the TUI plugin, `.opencode/plugins/fm-primary-watch-arm.js`, which restarts its own successor after each close | a `watcher` prompt through `promptAsync` |
+| omp | the watch extension, `.omp/extensions/fm-primary-omp-watch.ts`, which restarts its own successor after each close | the extension's `watcher` follow-up |
+| Grok | the model's tracked background call, rendered as `bin/fm-supervision-host.sh park` at session start | the background task's completion notification |
+| Codex | the foreground checkpoint, `bin/fm-watch-checkpoint.sh`, in the watcher's place | the checkpoint's own output |
+
+Hook, plugin, extension, and checkpoint owners pass their harness as the primary pin.
+Grok's model-owned call relies on primary detection.
+The host pins dispatched work to the primary's crew harness rather than the engine's.
+
+Grok's arm command is fixed when the session-start block renders.
+So adding or removing the file on a Grok home takes effect at the next session start.
+The other owners read the file at every arm.
+
+### The report surface
+
+`bin/fm-branch-report.sh` appends to the outcome store (`bin/fm-branch-outcome.sh`) plus a per-turn receipt the host requires.
+A row recorded after the captain returned is also queued for main as a durable check wake.
+
+### Leases and authority
+
+The host's engine runs with these settings:
+
+- `FM_SUPERVISION_ACTOR=branch`.
+- The session-lock holder as `FM_LEASE_HOLDER_PID`.
+- The primary's harness pin.
+
+So every guarded script treats it exactly as it treats the Pi branch.
 
 ## One away wake
 
-On each actionable close under the away record, the host first starts and verifies the successor watcher cycle and confirms the handling handoff, so the fleet stays supervised while the engine works.
-It then computes the branch-claimable rows, publishes the grant, and runs one bounded engine turn with the branch prompt and the wake message carrying the record's read-back.
-The engine drains, handles, reports through `bin/fm-branch-report.sh`, and acknowledges, exactly as the Pi branch does.
-The host counts the wake handled only when the turn exited cleanly, recorded at least one report, and left none of its granted rows in the wake queue; it releases the branch's leases and grant either way and parks on the successor only for a handled wake.
-A handled wake never reaches main, whether its outcome was routine or captain: captain outcomes wait in the outcome store, and the return brief (`bin/fm-afk-return.sh`) presents them.
-The one exception is a captain who returns while a turn is still running: the return brief was rendered before that turn's outcomes existed, so the host hands the close to main with those outcomes for main to relay, whether or not the turn handled its wake.
-That handoff is only the prompt delivery: each outcome recorded after the return is already a queued `check` wake, because the return owner archives the record before it reads the store and the report surface queues any row it records once the record is gone.
-So the outcome reaches main's drain even when the handoff is lost, as when a Cursor park superseded by the return turn's own end stops its host as the engine turn finishes.
+On each actionable close under the away record, the host runs these steps:
+
+1. It starts and verifies the successor watcher cycle and confirms the handling handoff, so the fleet stays supervised while the engine works.
+2. It computes the branch-claimable rows and publishes the grant.
+3. It runs one bounded engine turn with the branch prompt and the wake message carrying the record's read-back.
+   The engine drains, handles, reports through `bin/fm-branch-report.sh`, and acknowledges, exactly as the Pi branch does.
+4. It releases the branch's leases and grant, whether or not the wake was handled.
+5. It parks on the successor only for a handled wake.
+
+The host counts the wake handled only when all three hold:
+
+- The turn exited cleanly.
+- The turn recorded at least one report.
+- The turn left none of its granted rows in the wake queue.
+
+### Where a handled wake's outcome goes
+
+A handled wake never reaches main, whether its outcome was routine or captain.
+Captain outcomes wait in the outcome store, and the return brief (`bin/fm-afk-return.sh`) presents them.
+
+### A captain who returns during a turn
+
+The one exception to that rule is a captain who returns while a turn is still running.
+The return brief was rendered before that turn's outcomes existed.
+So the host hands the close to main with those outcomes for main to relay, whether or not the turn handled its wake.
+
+That handoff is only the prompt delivery.
+Each outcome recorded after the return is already a queued `check` wake, for two reasons:
+
+- The return owner archives the record before it reads the store.
+- The report surface queues any row it records once the record is gone.
+
+So the outcome reaches main's drain even when the handoff is lost.
+One example is a Cursor park superseded by the return turn's own end, which stops its host as the engine turn finishes.
 
 ## Failure direction
 
 Every path that cannot finish an away wake on the engine hands that wake to main, with one `supervision-host: <why>` line after the close.
-Before handing it back, the host stops its successor cycle, so the owner's next arm starts from the same state as without the host and the wake stays durable in the queue.
-That covers an unverified successor, a refused handoff, an unreadable queue, rows main already claimed, a missing engine or node, a turn that timed out or failed, a turn that recorded no report, and a turn that reported but left any of its granted rows unacknowledged.
-The last names those rows, which stay durable in the queue for main's drain.

+
+### Paths that hand the wake back
+
+- An unverified successor.
+- A refused handoff.
+- An unreadable queue.
+- Rows main already claimed.
+- A missing engine or node.
+- A turn that timed out or failed.
+- A turn that recorded no report.
+- A turn that reported but left any of its granted rows unacknowledged.
+  Its line names those rows, which stay durable in the queue for main's drain.
+
 A turn that fails also starts the next wake on a fresh engine conversation.
 When the captain returned during a failed turn that recorded outcomes, the handback carries those outcomes too, for main to relay.
+
+### Lost ownership
+
 When the host loses session-lock ownership or its auto-arm generation, it stands down silently and leaves continuity to whoever owns it now.
-A host that starts without that ownership stands down before activation, so it never stops the owner's host or watcher or releases its leases.
-A host that dies without a close is retried by its owner (Grok's model and Codex's checkpoint see it as a failed cycle and start the next one), and the next host stops, by recorded identity, whatever its predecessor left running, including the engine descendants a killed turn recorded, and removes that turn's files before it arms.

 ## The park boundary
 
-Claude drops the exit 2 of a Stop hook it terminated at the hook timeout ([verification](verification/supervision.md#claude-drops-the-exit-2-of-a-hook-it-timed-out-2026-09-23)), and Cursor's `stop` hook carries the same tracked 28,800-second registration.
-A plain watcher park rarely lasts that long, because heartbeat closes wake main, but a host absorbs its own wakes, so it ends its park itself before that registration.
-`FM_SUPERVISION_HOST_PARK_SECONDS` sets that boundary (default 27,000), and a value that is not a positive integer below 28,800 is treated as the default.
+The host stays parked across every close it handled itself and exits only when main is needed.

+
+### Setting the boundary
+
+`FM_SUPERVISION_HOST_PARK_SECONDS` sets that boundary (default 27,000).
+A value that is not a positive integer below 28,800 is treated as the default.
 The OpenCode, omp, and Grok owners have no hook timeout and keep the same default, so their parks end on the same cadence.
-At the boundary it stops the home's watcher and exits with one `supervision-host: cycle boundary` line; main drains and acknowledges, and the owner starts the next park (at the next turn end on Claude and Cursor, at once for OpenCode and omp, and at the model's re-arm on Grok).
+
+### At the boundary
+
+At the boundary the host stops the home's watcher and exits with one `supervision-host: cycle boundary` line.
+Main drains and acknowledges, and the owner starts the next park:
+
+| Primary | When the next park starts |
+|---|---|
+| Claude and Cursor | At the next turn end. |
+| OpenCode and omp | At once. |
+| Grok | At the model's re-arm. |
+
 The host checks the boundary on every loop pass, so closes that are already waiting cannot carry it past the boundary.
-It also starts no engine turn that could still be running at the boundary (the turn bound plus the engine grace), judged when the close arrives and again just before the turn starts: that close reaches main ahead of the boundary line instead, and its wake stays durable in the queue.
+It also starts no engine turn that could still be running at the boundary (the turn bound plus the engine grace).
+It judges this when the close arrives and again just before the turn starts.
+When it declines such a turn, that close reaches main ahead of the boundary line instead, and its wake stays durable in the queue.
 One short main turn per boundary is the cost of never losing the park silently.
 
-Codex has no asynchronous wake, so its checkpoint's own bound is the park: the checkpoint passes it as the boundary and reports the boundary as its ordinary quiet line (`checkpoint: no actionable wake within <n>s`).
-Attended the bound stays `FM_CODEX_WATCH_CHECKPOINT` (default 180 seconds); while the away record exists it is raised to `FM_CODEX_WATCH_CHECKPOINT_AWAY` (default 3,600) if longer, then capped at 27,000 seconds so a parked main is not woken every few minutes.
-Because that bound is not a harness timeout, the checkpoint also sets `FM_SUPERVISION_HOST_PARK_LIMIT`, which lets an engine turn that starts before the boundary finish after it; a captain message typed during the park waits for the checkpoint to return, at most the bound plus one engine turn, unless the captain interrupts it.

 ## Engine conversations
 
-The engine keeps one conversation across wakes so the byte-stable prompt stays cached, keyed to the current main session: every main session start opens a new one, and so does every `FM_SUPERVISION_HOST_ROTATE_TURNS` turns, because each wake adds history and the per-wake cost grows with it.
+The engine keeps one conversation across wakes so the byte-stable prompt stays cached.
+That conversation is keyed to the current main session.
+A new one opens in two cases:
+
+- At every main session start.
+- Every `FM_SUPERVISION_HOST_ROTATE_TURNS` turns, because each wake adds history and the per-wake cost grows with it.
+
 Nothing captain-facing rides on that conversation, because the outcome store carries every result.
-The engine sees no mirror of main's dialog; the away record's read-back at the tail of every wake is the captain context it acts on.
-`state/.supervision-host.log` records where every close went, and each engine turn's line carries its result, the engine's reported usage, the turn's cost, and the conversation's running cost, which is where engine cost is read today.

 ## Engines
 
 A verified engine is a headless mode of a harness whose isolation, actor propagation, promptless permissions, bounding, and caching were measured.
-Today the only verified engine is Claude's print mode, measured on Claude Code 2.1.278 and 2.1.281:
-
-- `--safe-mode` loads none of the home's hooks, `CLAUDE.md`, skills, plugins, or MCP servers, so the engine can never fire the home's own Stop or SessionStart hooks; `--bare` is unusable because it never reads claude.ai OAuth.
-- `--permission-mode dontAsk` with the `Bash` and `Read` allowlist never prompts: a denied call reaches the model as a tool error and never wedges the turn; `--safe-mode` does not override the user's default mode, so the mode is always passed.
-- Claude path-checks direct file reads against its working directories, so a home or state directory outside the code root is passed with `--add-dir`.
-- The conversation starts with `--session-id` and continues with `--resume`; the prompt is the first argument and stdin is `/dev/null`, because an open stdin costs a three-second wait.
-- `--output-format json` carries the error flag, turn count, usage, and the tool's own cost estimate; on a resumed conversation that cost is the conversation's running total while the usage and turn count are the turn's own, so the engine lib derives each turn's cost from the total the host recorded after the previous turn.
-- The host counts a turn successful only when that result is complete: `type` is `result`, `subtype` is `success`, `is_error` is false, and `total_cost_usd`, `num_turns`, and the four `usage` token counts (input, cache read, cache creation, output) are finite numbers; any other result fails the turn and hands its wake to main.
-- The engine runs from the tracked code root, so its session files land in Claude's own project store for that directory and appear in that directory's resume list.
-- Tool commands run in process groups of their own, which a bound's group signal cannot reach, so the engine lib records the engine's descendants once a second and reaps them by recorded identity after every turn; the reap is best-effort for what it observed, not a bound, so a process that a tool detaches into a process group of its own and that loses its ancestry to the engine between two snapshots is never recorded and survives the turn, the same residual `bin/fm-timeout-lib.sh` names.
+Today the only verified engine is Claude's print mode, measured on Claude Code 2.1.278 and 2.1.281.
+
+### Claude print mode behavior
+
+**Isolation**
+
+- `--safe-mode` loads none of the home's hooks, `CLAUDE.md`, skills, plugins, or MCP servers.
+  So the engine can never fire the home's own Stop or SessionStart hooks.
+- `--bare` is unusable because it never reads claude.ai OAuth.
 - From inside the engine's shell the primary is not in the harness ancestry, so the engine can never act as the session-lock owner.
 
-The default model is `sonnet`, which handled every measured wake correctly at a fraction of a larger model's cost; `config/supervision-host` can name another.
-The Claude engine runs beside any of the six primaries, but only a Claude primary selects it by default: a Cursor, OpenCode, omp, Grok, or Codex home names it (`claude`, optionally with a model) in `config/supervision-host`, and `/afk` there says so when the file selects no engine.
+**Permissions**
+
+- `--permission-mode dontAsk` with the `Bash` and `Read` allowlist never prompts.
+  A denied call reaches the model as a tool error and never wedges the turn.
+- `--safe-mode` does not override the user's default mode, so the mode is always passed.
+- Claude path-checks direct file reads against its working directories.
+  So a home or state directory outside the code root is passed with `--add-dir`.
+
+**Conversation and input**
+
+- The conversation starts with `--session-id` and continues with `--resume`.
+- The prompt is the first argument and stdin is `/dev/null`, because an open stdin costs a three-second wait.
+- The engine runs from the tracked code root.
+  So its session files land in Claude's own project store for that directory and appear in that directory's resume list.
+
+**Result and cost**
+
+- `--output-format json` carries the error flag, turn count, usage, and the tool's own cost estimate.
+- On a resumed conversation that cost is the conversation's running total, while the usage and turn count are the turn's own.
+  So the engine lib derives each turn's cost from the total the host recorded after the previous turn.
+- The host counts a turn successful only when that result is complete:
+  - `type` is `result`.
+  - `subtype` is `success`.
+  - `is_error` is false.
+  - `total_cost_usd`, `num_turns`, and the four `usage` token counts (input, cache read, cache creation, output) are finite numbers.
+- Any other result fails the turn and hands its wake to main.
+
+**Tool process reaping**
+
+Tool commands run in process groups of their own, which a bound's group signal cannot reach.
+So the engine lib records the engine's descendants once a second and reaps them by recorded identity after every turn.
+The reap is best-effort for what it observed, not a bound.
+A process escapes it when a tool detaches it into a process group of its own and it loses its ancestry to the engine between two snapshots.
+Such a process is never recorded and survives the turn, the same residual `bin/fm-timeout-lib.sh` names.
+
+### Model and engine selection
+
+The default model is `sonnet`, which handled every measured wake correctly at a fraction of a larger model's cost.
+`config/supervision-host` can name another.
+
+The Claude engine runs beside any of the six primaries, but only a Claude primary selects it by default.
+A Cursor, OpenCode, omp, Grok, or Codex home names it (`claude`, optionally with a model) in `config/supervision-host`.
+`/afk` there says so when the file selects no engine.

-`tests/fm-supervision-host.test.sh` drives the real host, auto-arm, grant, drain, report, and lease scripts against a stub engine.
-Each arm owner's own suite covers its host mode against a stub host: `tests/fm-claude-stop-autoarm.test.sh`, `tests/fm-cursor-primary.test.sh`, `tests/fm-pi-watch-extension.test.sh` (the OpenCode plugin), `tests/fm-omp-harness.test.sh`, `tests/fm-watch-checkpoint.test.sh`, and `tests/fm-supervision-instructions.test.sh` (the rendered protocol, including Grok's arm command).
-`tests/fm-supervision-host-live-e2e.test.sh` runs a real engine turn and is opt-in because it spends tokens.

 # Herdr runtime backend
 
+This page covers running Firstmate workers on the Herdr runtime backend: setup, where tasks appear, how they are cleaned up, how input reaches them, and how their liveness is read.
+Operators who choose Herdr, or who verify Firstmate against it, need it.
+
 Herdr is an agent-native terminal backend with native per-pane agent state and push events.
-Firstmate requires Herdr protocol 14 or newer; broad backend verification covers versions 0.7.1, 0.7.3, 0.7.4, 0.7.5, and 0.8.0, while protocol-16 features remain gated by availability.
+Firstmate requires Herdr protocol 14 or newer.
+Broad backend verification covers versions 0.7.1, 0.7.3, 0.7.4, 0.7.5, and 0.8.0.
+Protocol-16 features remain gated by availability.
 Default-on presentation spaces have a higher floor of Herdr 0.8.0 for the reason given under [Presentation spaces](#presentation-spaces).
 Herdr provides the terminal session while Treehouse continues to provide task worktrees.
 [`configuration.md`](configuration.md#runtime-backend-configbackend--fm_backend) owns shared backend selection and metadata semantics.

 ## Watching and task containers
 
 The ordinary topology puts one task tab per endpoint in the exact workspace of the Firstmate or secondmate that launches it.
 When the launcher has no Herdr workspace to inherit, the adapter maintains one durable home-labeled workspace instead.
-The primary home label is `firstmate`.
-A secondmate home label is `2ndmate-<secondmate-id>`, derived from its validated `.fm-secondmate-home` marker.
+
+| Home | Workspace label |
+| --- | --- |
+| Primary | `firstmate` |
+| Secondmate | `2ndmate-<secondmate-id>`, derived from its validated `.fm-secondmate-home` marker |
+
 A secondmate launched by the primary receives a narrowly scoped home override during container creation.
 
+### Watching tasks
+
 Attach to the selected named Herdr session and switch to the relevant home workspace to watch its task tabs.
 Routine supervision uses `bin/fm-peek.sh <id>` and `FM_HOME=<home> bin/fm-send.sh <id> '<text>'` without attaching.
 
+### Focus
+
 Workspace and tab creation use `--no-focus`.
-The first workspace in a completely empty Herdr session must become focused because no prior target exists, but later task creation does not intentionally steal focus.

+Later task creation does not intentionally steal focus.
+
+### Placement beside the launcher
 
 Herdr does not enforce workspace or tab label uniqueness, so a label can never decide where a worker goes.
-Herdr 0.7.5 exports `HERDR_ENV`, `HERDR_PANE_ID`, `HERDR_SESSION`, `HERDR_SOCKET_PATH`, `HERDR_TAB_ID`, and `HERDR_WORKSPACE_ID` into every process it manages a pane for, and a Firstmate or secondmate agent's own commands inherit them.

+A Firstmate or secondmate agent's own commands inherit them.
 Older injection shapes are unverified, so a claimed launcher pane without the injected socket identity cannot be trusted.
-With presentation spaces disabled, a crewmate or scout is created in the exact workspace that identity currently resolves to, read live from Herdr rather than from the injected snapshot, so the worker always appears beside the agent that launched it.

+That workspace is read live from Herdr rather than from the injected snapshot, so the worker always appears beside the agent that launched it.
 Duplicate labels elsewhere in the session are irrelevant, and the globally focused workspace is never the target.
 A `--secondmate` launch is the deliberate exception: it stands up that secondmate home's own workspace instead of joining the launcher's.
 
+### Unresolvable launcher identity
+
 A claimed parent identity that cannot be resolved exactly stops the spawn before any worker endpoint exists, rather than falling back to a label search.
-That covers a missing or unusable socket identity, a closed or unreadable launcher pane, a pane and tab that disagree about their workspace, a workspace missing from the session, and a pane belonging to another named session or Herdr server.

+
+### Firstmate running outside Herdr
 
 Firstmate running outside Herdr entirely has no launcher workspace to inherit, so its workers use this home's own labeled workspace, created on first use.
-That path needs the home label to identify exactly one workspace: two workspaces sharing it are an unresolvable placement and refuse rather than adopting either.
-Avoid naming a personal workspace `firstmate` or `2ndmate-<id>` for that reason, and because the adapter cannot distinguish that label collision from its own container.
-An older secondmate workspace using `firstmate-<id>` is not migrated automatically; rename it manually before expecting new tasks or recovery to use it.

 ## Presentation spaces
 
 Each new crewmate or scout is placed in a disposable one-task workspace by default, on Herdr 0.8.0 and newer.
-A home opts out by writing `off` into local gitignored `config/herdr-presentation-spaces`, and forces the projection on by writing `on`.
-An absent file leaves the choice to the version floor below, an empty file and the value `on` are both a deliberate opt-in, values are compared with whitespace stripped and case ignored, and an unrecognized value warns and follows the unconfigured default rather than failing a spawn over a purely visual setting.
-The empty file is the historical presence-based opt-in form, so every home that had already enabled the projection stays enabled with no migration step, and no previously enabled home can be turned off by the default or by the floor.
-A home that never created the file gains the projection at its next Herdr spawn on a supported release; that flip is deliberate, and it reaches only the Herdr backend because no other runtime backend has a projection path.
-
-Projecting each task into its own workspace makes every task cleanup a workspace-emptying removal, which is the only removal shape Herdr's pre-0.8.0 focus defect touches, and the focus-safe removal plan below can only avoid it while the closing pane's shell can be proved lone, childless, and idle.
-A persistent child of that shell - a `gitstatusd`, a `zsh-async` worker, or `direnv` - fails that proof permanently and forces the plain explicit close, which on those releases moves the active workspace for roughly a seventh of a second before the restore backstop pulls it back, once per task cleanup.
-An unconfigured home is therefore projected only on a release at or above the 0.8.0 floor, where every workspace-removal primitive preserves focus and that proof stops being load-bearing.
-Below the floor an unconfigured home uses the ordinary flat per-home layout instead and warns once per home per detected release, naming the running release and the upgrade that restores the projection.
-That one-warning-per-release record is a `state/.herdr-presentation-floor-<release>` marker; deleting it only makes the same warning appear again, and an upgrade or downgrade re-announces itself because the release is part of the key.
-The floor reads both the installed client's protocol and version and the selected named session's server signals while that server is running, requires both applicable releases to pass, and uses only the client when status positively reports no running server because that client will start it.
-The unconfigured default is rechecked after the server is started or adopted and before any presentation journal or workspace is created, while an unreadable server state or release is treated as unsupported rather than guessed at.
-An explicit `on` is honored below the floor, so a home that deliberately opted in is never silently downgraded; it accepts that documented focus move, and the exact prior-tab restore stays its backstop.
-The floor has a single owner, the spawn-time gate, so cleanup for a projection that already exists always runs and never strands a workspace, whatever release the home is on now.
-Upgrading Herdr to 0.8.0 or newer is the fix; writing `off` is the immediate mitigation for a home that cannot upgrade yet.
-The setting is inherited into secondmate homes through the normal configuration-convergence owner, and the default needs no special convergence: the primary's absent file and the secondmate's absent file both mean the same unconfigured default, so leaving it converges a secondmate to that same default rather than turning it off, and only an explicit primary `off` propagates the opt-out.
+This section calls that one-task workspace the projection.
+Without the projection, tasks use the ordinary flat layout described under [Watching and task containers](#watching-and-task-containers).
+
+### Setting values
+
+The local gitignored `config/herdr-presentation-spaces` file controls the projection.
+
+| File state | Result |
+| --- | --- |
+| Absent | Leaves the choice to the version floor below (the unconfigured default). |
+| `off` | Opts the home out. |
+| `on` | Forces the projection on, as a deliberate opt-in. |
+| Empty | A deliberate opt-in, the same as `on`. |
+| Any other value | Warns and follows the unconfigured default rather than failing a spawn over a purely visual setting. |
+
+Values are compared with whitespace stripped and case ignored.
+
+The empty file is the historical presence-based opt-in form.
+So every home that had already enabled the projection stays enabled with no migration step.
+No previously enabled home can be turned off by the default or by the floor.
+
+A home that never created the file gains the projection at its next Herdr spawn on a supported release.
+That flip is deliberate.
+It reaches only the Herdr backend, because no other runtime backend has a projection path.
+
+### Why the default needs Herdr 0.8.0
+
+Projecting each task into its own workspace makes every task cleanup a workspace-emptying removal.
+That is the only removal shape Herdr's pre-0.8.0 focus defect touches.
+The focus-safe removal plan below can only avoid the defect while the closing pane's shell can be proved lone, childless, and idle.
+
+A persistent child of that shell - a `gitstatusd`, a `zsh-async` worker, or `direnv` - fails that proof permanently and forces the plain explicit close.
+On those releases, that close moves the active workspace for roughly a seventh of a second before the restore backstop pulls it back, once per task cleanup.
+
+An unconfigured home is therefore projected only on a release at or above the 0.8.0 floor.
+On those releases every workspace-removal primitive preserves focus, and that proof stops being load-bearing.
+
+Below the floor, an unconfigured home uses the ordinary flat per-home layout instead.
+It warns once per home per detected release, naming the running release and the upgrade that restores the projection.
+That one-warning-per-release record is a `state/.herdr-presentation-floor-<release>` marker.
+Deleting it only makes the same warning appear again.
+An upgrade or downgrade re-announces itself because the release is part of the key.
+
+### How the floor is checked
+
+The floor reads two sources:
+
+- The installed client's protocol and version.
+- The selected named session's server signals, while that server is running.
+
+Both applicable releases must pass.
+When status positively reports no running server, the floor uses only the client, because that client will start it.
+
+The unconfigured default is rechecked after the server is started or adopted, and before any presentation journal or workspace is created.
+An unreadable server state or release is treated as unsupported rather than guessed at.
+
+An explicit `on` is honored below the floor, so a home that deliberately opted in is never silently downgraded.
+That home accepts the documented focus move, and the exact prior-tab restore stays its backstop.
+
+The floor has a single owner, the spawn-time gate.
+So cleanup for a projection that already exists always runs and never strands a workspace, whatever release the home is on now.
+
+Upgrading Herdr to 0.8.0 or newer is the fix.
+Writing `off` is the immediate mitigation for a home that cannot upgrade yet.
+
+### Secondmate homes
+
+The setting is inherited into secondmate homes through the normal configuration-convergence owner.
+The default needs no special convergence.
+The primary's absent file and the secondmate's absent file both mean the same unconfigured default.
+So leaving the file absent converges a secondmate to that same default rather than turning it off.
+Only an explicit primary `off` propagates the opt-out.
+
 A secondmate agent itself always stays in its ordinary parent workspace; only children launched by that home are eligible.
 An unconverged opt-out keeps the default projection in that home until convergence.
 
+### Presentation journal
+
 Presentation is a best-effort visual projection, never task ownership or lifecycle authority.
+A presentation journal is the per-task record in this home's `state/` that binds a task to its projected workspace.
+
 Only a fresh task with neither metadata nor an existing presentation journal is eligible for projected creation.
-Firstmate atomically publishes a three-field version 1 journal containing a random 128-bit base64url token before asking Herdr to create anything.
-After the new workspace converges to one exact task endpoint beneath one exact parent workspace id, the journal advances to a version 2 binding that records the physical home, named session, endpoint, parent, and immutable expected labels.
+Creation proceeds in this order:
+
+1. Firstmate atomically publishes a three-field version 1 journal containing a random 128-bit base64url token, before asking Herdr to create anything.
+2. After the new workspace converges to one exact task endpoint beneath one exact parent workspace id, the journal advances to a version 2 binding.
+   That binding records the physical home, named session, endpoint, parent, and immutable expected labels.
+
 Another parent with the same presentation label does not prevent publication or participate in restart reclaim.
-The token is visible in the workspace title because Herdr exposes no verified hidden persistent field, but neither token, title, nor journal authorizes send, capture, task ownership, Treehouse return, or general recovery.
 
-The owning parent is the launcher's own exact workspace, resolved from the same identity the flat path uses, and falls back to a unique home-label lookup only for a Firstmate outside Herdr.
-Projected children are never collapsed back into that parent; it is the placement and ordering reference the projection is bound under.

 The normal `fm-<id>` task tab is created in the exact new workspace returned by Herdr.
 Only the exact seeded default tab returned by the same workspace-create response can be pruned.
 Before and after create, prune, order, abort cleanup, and normal cleanup, Firstmate verifies exact workspace, tab, pane, and active-focus ids.
 An ambiguous response grants no mutation or cleanup authority.
 
+### Ordering
+
 Protocol 16 exposes `workspace.move` over the named session socket but no CLI subcommand.
 `bin/backends/herdr-workspace-move.py` sends only that whitelisted method and verifies the complete returned workspace order.
-Projected children are placed in one contiguous block immediately after their owning home when the session layout, protocol, socket, `python3`, and machine-private per-session lock are all verifiable.

+Herdr 0.7.5's explicit close moves focus to a neighbor whenever it empties a non-focused workspace.
+Its pane-death removal preserves the focused workspace whenever the dying workspace sits behind it or the focused workspace is last.
+Both behaviors are fixed in Herdr 0.8.0, and the exact rules live in the adapter header of `bin/backends/herdr.sh`.
+
+Projected cleanup therefore:
+
+- Runs under the same session lock.
+- Refuses to delete the tab a live foreground client is viewing.
+- Treats a workspace-emptying close as a focus-safe removal.
+
+A focus-safe removal takes these steps:
+
+1. Verify the close would empty the workspace.
+2. When needed, reposition the doomed workspace behind the focused one through the verified `workspace.move` transport.
+3. Prove the pane holds one lone idle shell.
+4. End that shell, so Herdr removes the emptied workspace through its focus-preserving pane-death path.
+
+The persisted `.focused` pointer is not a live viewer.
+When `herdr terminal title clear` reports `no_foreground_client`, cleanup proceeds on that tab because no human is attached, and skips restoration of the tab it destroys.
+
+Herdr currently has no atomic client-aware mutation.
+So a fresh target-focus and foreground-client checkpoint runs immediately before each move, signal, or explicit close.
+When a live viewer has switched to another tab, that fresh tab becomes the restore target.
+A client can still attach or switch focus in the residual checkpoint-to-mutation window.
+A durable atomic close is deferred until Herdr exposes that primitive.
+
+The repositioning move-to-last preserves every surviving workspace's relative order.
+Removal is confirmed against the exact moved workspace rather than inferred from pane disappearance.
+An unconfirmed removal then makes one verified attempt, under the same session lock, to roll the doomed workspace back to its exact original position.
 If that rollback cannot restore the verified original order, cleanup warns loudly and leaves the retained records for inspection rather than retrying the shared-layout mutation.
-The pane-death signals are pid-exact: the escalation re-reads the pane's process information and refuses unless the same shell pid still passes the strict bare-idle ownership proof, so an exited and reused pid is never signaled.
-A move-plan ambiguity, unsupported or failed move, or unproved shell falls back to the plain explicit close, and exact tab restoration remains the backstop whenever a surviving tab must be preserved, so degraded behavior is never worse than the pre-mitigation sub-second restore.
-Ordinary non-projected task removal serializes through the same session lock, applies the same focus-safe plan when its close would empty a non-focused workspace, keeps the legitimate plain close when the target is the active tab, and refuses an unlocked close if the lock cannot be acquired.
-Task cleanup acquires that session lock before the task's isolated copy is returned, so a contended lock refuses up front while the copy, every durable record, and the endpoint are all intact for a plain rerun.
-Forced secondmate cleanup recursively preflights every Herdr child endpoint and acquires every affected named-session lock before mutating any child, then retains each child's durable identity unless that exact pane returns structured not-found after its close.
-Durable task records are erased only once the exact pane is confirmed gone through its structured presence: after every close path, only a structured not-found response counts as gone, while a present or unknown result retains every record with a visible, retryable error.

+Ordinary non-projected task removal:
+
+- Serializes through the same session lock.
+- Applies the same focus-safe plan when its close would empty a non-focused workspace.
+- Keeps the legitimate plain close when the target is the active tab.
+- Refuses an unlocked close if the lock cannot be acquired.

+Task cleanup acquires that session lock before the task's isolated copy is returned.
+So a contended lock refuses up front while the copy, every durable record, and the endpoint are all intact for a plain rerun.
+
+Forced secondmate cleanup recursively preflights every Herdr child endpoint and acquires every affected named-session lock before mutating any child.
+It then retains each child's durable identity unless that exact pane returns structured not-found after its close.
+
+### When task records are erased
+
+Durable task records are erased only once the exact pane is confirmed gone through its structured presence.
+After every close path, only a structured not-found response counts as gone.
+A present or unknown result retains every record with a visible, retryable error.
 Missing or malformed endpoint identity and missing confirmation machinery are ambiguity, never proof of a gone pane, and refuse record removal the same way.
 If lock, snapshot, pane identity, or restoration is ambiguous, cleanup warns and preserves the journal for manual inspection.
 
+### Restart recovery
+
 Recovery is deliberately conservative and presentation-only.
 An existing journal suppresses another projected create.
 Before any recovery mutation, Firstmate holds both the task spawn lock and the named-session presentation lock.
-A same-identity version 2 binding may replace one exact agent-free restart husk in place only when the physical home, session, metadata endpoint, unique token match, workspace shape and labels, parent identity and placement, and non-target focus snapshot all agree.

+
+A same-identity version 2 binding may replace one exact agent-free restart husk in place.
+A husk is a restored same-labeled tab with a missing pane or no registered agent, as [Restart and liveness behavior](#restart-and-liveness-behavior) describes.

+
+- The physical home.

+- The parent identity and placement.
+- The non-target focus snapshot.
+
+The replacement tab and pane are created and verified before the old pane is rechecked and closed.
+Then the journal advances atomically to the replacement endpoint before metadata publication.
 The reclaim path never moves, closes, deletes, or renames a workspace and never touches a parent, sibling, captain, or foreign pane.
 A failed replacement rolls back only the exact response-derived new pane when focus-safe verification permits it.
-Version 1 journals, dead or missing panes, duplicate or absent tokens, renamed or detached spaces, cross-home mismatches, inconsistent endpoint bindings, active target tabs, and ambiguous identity or focus fall back flat without mutating the old projection when duplicate-agent risk is positively absent.

-Before cleanup, Firstmate acquires the existing task-id spawn lock and then the shared named-session presentation lock.
-Inside both locks it takes one exact snapshot, requires one unambiguous non-target focus and the exact title, token, tab, and pane shape, positively confirms no registered agent, and reads Herdr's process information for the exact named-session pane.
-The process proof requires one recognized idle shell as both the shell process and the sole foreground process-group member, an operating-system process-table row for that shell, no child process, and a sleeping or idle shell state.
-The proof retries strict single samples for a bounded settle window because an idle interactive shell transiently hosts short-lived prompt helpers; a genuinely busy pane fails every sample.
+A candidate must meet all of these conditions:

+3. Require one unambiguous non-target focus and the exact title, token, tab, and pane shape.

+5. Read Herdr's process information for the exact named-session pane and apply the process proof below.
+6. Immediately revalidate the same journal, metadata absence, workspace title and token uniqueness, one-tab and one-pane topology, exact pane relationship, absent agent, process proof, and non-target focus.
+7. Call the existing exact-pane focus-preserving close helper.

+8. Retire the matching journal only after the exact pane is positively confirmed gone.

-Firstmate immediately revalidates the same journal, metadata absence, workspace title and token uniqueness, one-tab and one-pane topology, exact pane relationship, absent agent, process proof, and non-target focus before calling the existing exact-pane focus-preserving close helper.

-- Recovery of an existing presentation journal deliberately refuses the spawn when the shared presentation lock is contended rather than falling back flat, and default-on makes that refusal reachable in any Herdr home.

 `bin/fm-composer-lib.sh` is the fleet-wide owner that strips dim or faint runs and dark truecolor placeholders while retaining bright typed input.
-If the ANSI capture ever fails, the plain fallback declares itself unstyled and the classifier degrades a glyph row carrying trailing text to `unknown` instead of misreading ghost suggestions as typed input, which safely defers injection and eventually raises the wedge alarm.

 A registration alone never proves an agent.
-Herdr keeps a Pi registration (`agent get` still reports `agent=pi` with its last status) after the Pi process has exited to a plain shell whenever a nested interactive shell sits under the pane's top shell, which is the crew shape `treehouse get` leaves behind (measured on Herdr 0.9.0 - [verification](verification/runtime-backends.md) "Stale agent registration"; upstream issue #4115).
-So before a registered agent counts as live, the pane classifier reads `pane process-info` and the real process table through the shared harness-process classifier in `bin/fm-agent-process-lib.sh`, the same rule the tmux adapter proves liveness with: a harness in the foreground process group, or still a descendant of the pane shell, keeps the registration live; a foreground that is nothing but shells with no harness descendant is a `stale-agent` pane, agent-free with that explicit reason; a foreground holding anything else keeps the registration live, but only after the same bounded settle window the idle-shell proof uses, because an idle shell transiently hosts prompt helpers such as starship in its foreground group and the first agent or shell sample in that window decides; an unreadable process view makes the pane `unknown`, trusting neither the registration nor its absence.
-No registered status outranks the process view, because an agent killed mid-turn leaves `working` behind just as a quit one leaves `idle`, and the native busy verdict is verified the same way so a shell-only pane never reads busy.
+Herdr keeps a Pi registration after the Pi process has exited to a plain shell, whenever a nested interactive shell sits under the pane's top shell.
+In that case `agent get` still reports `agent=pi` with its last status.
+That nested shell is the crew shape `treehouse get` leaves behind (measured on Herdr 0.9.0 - [verification](verification/runtime-backends.md) "Stale agent registration"; upstream issue #4115).
+
+So before a registered agent counts as live, the pane classifier reads `pane process-info` and the real process table.
+It uses the shared harness-process classifier in `bin/fm-agent-process-lib.sh`, the same rule the tmux adapter proves liveness with:
+
+| What the process view shows | Verdict |
+| --- | --- |
+| A harness in the foreground process group, or still a descendant of the pane shell | The registration stays live. |
+| A foreground that is nothing but shells, with no harness descendant | A `stale-agent` pane: agent-free, with that explicit reason. |
+| A foreground holding anything else | The registration stays live, but only after the same bounded settle window the idle-shell proof uses. |
+| An unreadable process view | The pane is `unknown`, trusting neither the registration nor its absence. |
+
+The settle window exists because an idle shell transiently hosts prompt helpers such as starship in its foreground group.
+The first agent or shell sample in that window decides.
+
+No registered status outranks the process view, because an agent killed mid-turn leaves `working` behind just as a quit one leaves `idle`.
+The native busy verdict is verified the same way, so a shell-only pane never reads busy.
+
+### Process-view version support
+
 The `pane process-info` subcommand that this process-level proof depends on is present in every supported release client from the 0.7.1 floor upward (measured 2026-09-10 on the pinned 0.7.1, 0.7.3, 0.7.4, and 0.7.5 release clients - [verification](verification/runtime-backends.md) "Stale agent registration").
-The response shape the adapter parses (`result.type` of `pane_process_info`, `process_info.shell_pid`, and `foreground_processes` entries carrying `name`, `argv0`, `argv`, and `cmdline`) is verified live only on Herdr 0.9.0, with the idle-shell proof's narrower parse previously verified on 0.7.5.

+The idle-shell proof's narrower parse was previously verified on 0.7.5.
 A server response below 0.9.0 has not been measured for this parse.
 An unreadable or unparseable process view reads `unknown`, which refuses lifecycle verbs and recovery rather than trusting the registration.
 
+### Agent-liveness probe
+
 The generic Herdr agent-liveness probe reuses that pane classifier, then applies one recovery-only exception.
-A structurally gone pane or a pane read from a session positively reported as having no running server becomes `missing`, a restored agent-less shell and a stale registration over a shell-only pane both become `dead`, a registered agent with a live process becomes `alive`, and every other unexpected read becomes `unreadable`.
-Neither the stopped-server exception nor the stale-registration verdict widens husk detection or any close authority; those paths still refuse an unreadable pane, and a `stale-agent` pane is reused by recovery, never closed as a husk, because the shell it holds may be a nested worktree shell.
-Native registration still identifies Pi by name where tmux would see a generic interpreter; the process-level proof only decides whether that registration is backed by a running process.
-`tests/fm-backend-herdr-agent-exit-shell-e2e.test.sh` pins the live-Pi versus leftover-shell distinction; [`verification/runtime-backends.md`](verification/runtime-backends.md#agent-lifecycle-control) owns the versioned evidence.
 
-The session-start sweep and the watcher's dedicated secondmate liveness tick use this probe; idle secondmates remain exempt from stale-pane escalation.

+## Overview
+
 Fleet supervision on the Pi primary harness runs on a second conversation - the supervision branch - inside the same `pi` process as the captain's chat.
-Supervision is default-on: once a Pi primary session owns this home's fleet lock, the branch handles eligible task-local rows from ordinary actionable wakes plus heartbeat scans that the cheap bash-level scan flags as possibly captain-relevant, then merges each outcome back into the captain conversation's transcript.
-Ordinary main-only rows remain on main even when eligible task-local rows share their queue, except that a decision-owned signal or stale trigger keeps its entire coalesced trigger batch on main.
-An unresolvable row makes the scan unsafe and returns the whole wake to main, and every watcher-failure alarm also stays on main.
-All of that describes the attended posture; the away posture, recorded by `state/.afk-contract`, hands every row to the branch and parks main (see "Postures" below).
-While attended, captain-relevant branch outcomes persist as exact, sequence-keyed visible transcript entries and then open one sequence-keyed processing turn on main, which stays open until main acknowledges that sequence; while away, the entries persist but processing waits until the record is archived.
-The design source is the captain-approved forked-supervision architecture board, a captain-private fleet record (a self-contained HTML explainer with the measured cache and judgment evidence); this document records the shape it landed as, and the delivering PR cites the board artifact itself.
+
+### What the branch handles while attended
+
+Supervision is default-on.
+Once a Pi primary session owns this home's fleet lock, the branch handles two kinds of work:
+
+- Eligible task-local rows from ordinary actionable wakes.
+  A row is one queued wake entry.
+- Heartbeat scans that the cheap bash-level scan flags as possibly captain-relevant.
+
+The branch then merges each outcome back into the captain conversation's transcript.
+
+Some wakes stay on main:
+
+- Ordinary main-only rows remain on main even when eligible task-local rows share their queue.
+- A decision-owned signal or stale trigger keeps its entire coalesced trigger batch on main.
+- An unresolvable row makes the scan unsafe and returns the whole wake to main.
+- Every watcher-failure alarm also stays on main.
+
+All of that describes the attended posture.
+The away posture, recorded by `state/.afk-contract`, hands every row to the branch and parks main (see "Postures" below).
+
+### How outcomes reach main
+
+While attended, captain-relevant branch outcomes persist as exact, sequence-keyed visible transcript entries.
+They then open one sequence-keyed processing turn on main, which stays open until main acknowledges that sequence.
+While away, the entries persist but processing waits until the record is archived.
+
+### Design source
+
+The design source is the captain-approved forked-supervision architecture board.
+That board is a captain-private fleet record: a self-contained HTML explainer with the measured cache and judgment evidence.
+This document records the shape it landed as, and the delivering PR cites the board artifact itself.
+
+### Pi-only scope
 
 This in-process supervision branch is Pi-only by construction:
 
-- The branch lives in `.pi/extensions/fm-branch-supervision.ts`, which only a Pi primary ever loads; no other harness gains branch supervision behavior.
-- In a home with no branch state, the bash-side additions remain inert (`tests/fm-branch-supervision.test.sh`); `bin/fm-lease-lib.sh` owns how a pre-existing lease is honored on any harness.

 ## Components and their owners
 
-- Wake dispatch: `.pi/extensions/fm-primary-pi-watch.ts` stays the dispatcher; `.pi/extensions/lib/fm-branch-dispatch.ts` owns the offer handshake and row eligibility, while [`watcher-continuity.md`](watcher-continuity.md#per-actor-acknowledgement) owns the per-actor consume contract.
-  A successful row grant transfers ownership of exactly the currently branch-eligible rows to the branch; while attended a check-kind triggering close (merge-confirmation polls, Relay mentions, credential/auth failures, and every other legitimately main-only class) is never offered even when other rows are eligible, no acceptor (extension absent, branch broken) keeps today's wake-to-main path for that close, and watcher-failure alarms always go to main because only main can repair the watcher cycle.
-  Under the away-posture record the check-kind and decision-owned exclusions lift and every actionable row is offered ("Postures" below), while the no-acceptor fallback and the alarms still reach main.
-  A decision-owned event surfaced by `bin/fm-watch.sh`'s signal path gets the identical treatment even though it keeps the ordinary `signal` kind.
-  `signal_files_actionable` marks the queued payload `needs-decision:` for a newly surfaced `needs-decision`, a `captain-held` declaration surfaced through the no-verb fallback, or a pending-reply second-mate escalation; `scopeForUnreadWake` excludes every marked row from what the branch may claim.
-  For a stale row, `scopeForUnreadWake` folds the mapped task's status log and excludes the row when any `needs-decision` remains open or the current meaningful declaration is `captain-held`; an unreadable or symlinked status log fails the scope closed rather than influencing routing.
-  The dispatcher resolves trigger keys and every currently unread excluded decision row to task identity before cross-referencing them: any signal or stale trigger containing a decision-owned task goes wholly to main, including a batch that also contains routine rows, and an unread decision for one task keeps every later signal or stale trigger for that same task on main until the decision row is read, regardless of whether the rows use its status-file key or window alias.
-  Other tasks remain independently eligible.
-  The wake message itself retains its existing shape, so other harness-arm scripts remain unchanged.
-  Heartbeat handling remains independent.
-  A fleet-wide heartbeat keeps its own all-or-nothing rule (see "Heartbeat routing" below): it takes every branch-ownable unread row or none of them.
-  A co-present main-owned check row no longer defers that review to main, because it is not fleet context the branch is missing and main is woken for it on its own triggering close.
-- The branch itself: `.pi/extensions/fm-branch-supervision.ts` creates the branch session, serializes wakes, mirrors dialog, and merges outcomes.
-  The branch conversation lasts for exactly one main session: every main session start - a cold start, `/new`, `/resume`, `/fork`, or a reload - opens a NEW branch conversation, and a conversation recorded by an earlier session is never reopened as the live one.
-  That keeps the branch reasoning from the current generated prompt and the current main dialog rather than from weeks of accumulated thread, where a superseded rule could still outweigh today's.
-  Only a rebuild inside one main session, which is what a model or effort change triggers, continues that session's own conversation, and `state/.branch-session` records it.
-  Earlier conversations stay on disk under `state/branch-session/`, exactly as Pi keeps its own session files, and are never reopened as live branch context; the effort picker may only inspect the model named by the current pointer as the last-resort lookup documented in [configuration.md](configuration.md#pi-supervision-branch-model-and-effort-configsupervision-branch-model-configsupervision-branch-effort).
-  Nothing captain-facing rides on that conversation: the durable outcome store and its processed marker are what carry unacknowledged outcomes across the boundary, and they re-present on the new main session exactly as they do after a crash.
-  It checks the current extension generation and `state/.lock` ownership before each guarded branch side effect so replacement or lock loss cannot let an old continuation mutate the new session.
-  Those checks and the store calls around them are awaited rather than synchronous, and an explicit queue inside the extension is what keeps them serialized (see "Off-thread delivery" below).
-  Every accepted path that cannot reach a working branch rejects its settlement to the watcher, which retains delivery ownership and routes the wake to main as a follow-up that counts as delivered once Pi accepts it; a broken branch declines later offers so they take that path directly.
-  After wake rows are claimed, a branch prompt counts as handled only when `fm_branch_report` appends a durable outcome before that prompt settles; a settled provider error or a settled prompt with no report releases the grant and rejects delivery ownership back to the watcher.
-  While a signal or stale prompt is open, `fm_branch_report` accepts only the tasks that prompt's claimed rows resolve to (a signal row by its status-log key, a stale row through the task record naming that endpoint); a report for any other task id, `fleet` included, is refused before the store is touched, so a task remembered from an earlier wake cannot become a delivered outcome, while a heartbeat review is not scoped by task.
-  The branch's guarded commands never tell it to drain queued rows mid-handling: for that actor `bin/fm-guard.sh` keeps the queued-wakes warning silent, and an acknowledgement that consumed nothing reports that plainly with the exact command for the current wake (`docs/watcher-continuity.md` "Per-actor acknowledgement").
-  Two consecutive settled provider errors latch the branch broken and surface a one-line health note only on that initial trip.
-  Main keeps every wake during a five-minute cooldown, after which one wake may probe the branch while concurrent wakes still stay on main; each probe that settles with another provider error doubles the next cooldown up to one hour.
-  A prompt from the current branch generation and model or effort selection that appends a durable `fm_branch_report` and then settles without a provider error clears both the latch and provider-error streak and surfaces a one-line recovery note; a provider error settled after that report wins instead, re-latches the branch, and extends the cooldown.
-  A session replacement or branch model or effort change resets the recovery state immediately.
-- Branch model and effort selection: the same extension registers `/supervision-model`, which picks the branch's model and then its reasoning effort, and applies both at the branch-session creation boundary; [configuration.md](configuration.md#pi-supervision-branch-model-and-effort-configsupervision-branch-model-configsupervision-branch-effort) owns the operator-facing schema and behavior.
-- Branch system prompt: `bin/fm-branch-prompt.sh`; its header owns the byte-stable-prefix contract (no timestamps, no fleet snapshot, no per-wake content).
-- Outcome store: `bin/fm-branch-outcome.sh`; its header owns the append-only format, read cursor, and bounded per-task status-coverage indexes.
-  Outcomes are written to the store before delivery to Pi.
-  A captain row advances the cursor only after its matching visible session entry exists, while locked session-start replay stops before the first captain row so it cannot acknowledge that outcome through prose alone.
-  A routine note has no such sequence-keyed record, so if its cursor write fails after the note was delivered the next reconciliation sends that note once more.
-  That asymmetry is a known limitation of the routine delivery representation rather than of the ordering above, it predates delivery moving off Pi's render thread, and closing it means giving routine delivery a durable idempotent record - tracked as follow-up `fm-pi-routine-delivery-idempotency-followup-r1` and pinned meanwhile by `tests/fm-pi-branch-extension.test.sh`.
-- Consistency: `bin/fm-lease-lib.sh` owns the per-task lease contract, the posture-aware main-only role partition, and the deliberate CONFUSED-AGENT-GRADE threat model these guards target (captain-decided; adversarial-grade separation is out of scope and tracked as follow-up design work); `bin/fm-lease.sh` is the command surface.
-  The guards are wired into `fm-send.sh`, `fm-control.sh`, and `fm-teardown.sh` (overlap, lease-checked, with claim serialization retained through the mutation) and `fm-pr-merge.sh`, `fm-merge-local.sh`, `fm-spawn.sh`, and `fm-send.sh --resolve-key` for a decision key (main-owned while attended, branch refused; a relaunch through `fm-control` stays branch-legal recovery in both postures).
-  Under the away-posture record the PR merge, a fresh spawn, and a decision answer relocate to the branch behind each script's own gate, and local-only landing never does ("Postures" below).
-- Autonomy: supervision is default-on for every task once a Pi primary session owns the fleet lock (docs/configuration.md "Pi supervision branch"); no captain grant file is required.
-  A fleet-wide heartbeat is separately eligible only when every row other than a check or decision-owned signal/stale row is a heartbeat row or a resolvable task-local row (see "Heartbeat routing" below); every other fleet-wide or unresolvable wake, and every watcher-failure alarm, stays on main.
-  The branch recomputes eligibility immediately before prompting the branch to drain and publishes the exact eligible row set to `state/.branch-eligible-rows` through `writeEligibleRowsSnapshot`.
-  After an independently eligible wake has already been offered, a newly-arrived main-owned row observed at that pre-drain recheck does not revoke the offer: it is excluded from the eligible set, so whatever else is currently eligible still reaches the branch, and the main-owned row stays queued for main's own drain.
-  [`watcher-continuity.md`](watcher-continuity.md#per-actor-acknowledgement) owns the consume-side guarantee that neither actor can present or acknowledge the other's claim.
-  Heartbeat keeps its own all-or-nothing recheck over the rows it can claim: it takes every branch-ownable unread row or none of them, and an unresolvable task-local row still defers the whole review to main.
-  A producer can still append a row in the instant between that final check and drain startup; this accepted residual follows the confused-agent-grade boundary above rather than claiming adversarial queue isolation.
-  A broken branch between its bounded recovery probes keeps today's wake-to-main behavior in both postures; the legacy `state/.afk` daemon flag means nothing on Pi, where the daemon is never launched.

+#### Decision-owned rows
+
+A decision-owned event surfaced by `bin/fm-watch.sh`'s signal path gets the same treatment as a check-kind triggering close, even though it keeps the ordinary `signal` kind.
+`signal_files_actionable` marks the queued payload `needs-decision:` for any of these:
+
+- A newly surfaced `needs-decision`.
+- A `captain-held` declaration surfaced through the no-verb fallback.
+- A pending-reply second-mate escalation.
+
+`scopeForUnreadWake` excludes every marked row from what the branch may claim.
+
+For a stale row, `scopeForUnreadWake` folds the mapped task's status log.
+It excludes the row when any `needs-decision` remains open or the current meaningful declaration is `captain-held`.
+An unreadable or symlinked status log fails the scope closed rather than influencing routing.
+
+Before cross-referencing them, the dispatcher resolves trigger keys and every currently unread excluded decision row to task identity.
+The cross-reference then applies two rules:
+
+- Any signal or stale trigger containing a decision-owned task goes wholly to main, including a batch that also contains routine rows.
+- An unread decision for one task keeps every later signal or stale trigger for that same task on main until the decision row is read.
+  This holds regardless of whether the rows use its status-file key or window alias.
+
+Other tasks remain independently eligible.
+The wake message itself retains its existing shape, so other harness-arm scripts remain unchanged.
+
+#### Heartbeats during dispatch
+
+Heartbeat handling remains independent.
+A fleet-wide heartbeat keeps its own all-or-nothing rule (see "Heartbeat routing" below): it takes every branch-ownable unread row or none of them.
+A co-present main-owned check row no longer defers that review to main.
+That row is not fleet context the branch is missing, and main is woken for it on its own triggering close.
+
+### The branch itself
+
+`.pi/extensions/fm-branch-supervision.ts` creates the branch session, serializes wakes, mirrors dialog, and merges outcomes.
+
+#### One conversation per main session
+
+The branch conversation lasts for exactly one main session.
+Every main session start - a cold start, `/new`, `/resume`, `/fork`, or a reload - opens a NEW branch conversation.
+A conversation recorded by an earlier session is never reopened as the live one.
+That keeps the branch reasoning from the current generated prompt and the current main dialog rather than from weeks of accumulated thread, where a superseded rule could still outweigh today's.
+
+A model or effort change triggers a rebuild inside one main session.
+Only such a rebuild continues that session's own conversation, and `state/.branch-session` records it.
+
+Earlier conversations stay on disk under `state/branch-session/`, exactly as Pi keeps its own session files.
+They are never reopened as live branch context.
+The effort picker may only inspect the model named by the current pointer, as the last-resort lookup documented in [configuration.md](configuration.md#pi-supervision-branch-model-and-effort-configsupervision-branch-model-configsupervision-branch-effort).
+
+Nothing captain-facing rides on that conversation.
+The durable outcome store and its processed marker are what carry unacknowledged outcomes across the boundary.
+They re-present on the new main session exactly as they do after a crash.
+
+#### Guarded side effects and delivery ownership
+
+Before each guarded branch side effect, the extension checks the current extension generation and `state/.lock` ownership.
+That way, replacement or lock loss cannot let an old continuation mutate the new session.
+Those checks and the store calls around them are awaited rather than synchronous.
+An explicit queue inside the extension is what keeps them serialized (see "Off-thread delivery" below).
+
+Every accepted path that cannot reach a working branch rejects its settlement to the watcher.
+The watcher retains delivery ownership and routes the wake to main as a follow-up, which counts as delivered once Pi accepts it.
+A broken branch declines later offers, so they take that path directly.
+
+After wake rows are claimed, a branch prompt counts as handled only when `fm_branch_report` appends a durable outcome before that prompt settles.
+A settled provider error, or a settled prompt with no report, releases the grant and rejects delivery ownership back to the watcher.
+
+#### Report scoping
+
+While a signal or stale prompt is open, `fm_branch_report` accepts only the tasks that prompt's claimed rows resolve to:
+
+- A signal row resolves by its status-log key.
+- A stale row resolves through the task record naming that endpoint.
+
+A report for any other task id, `fleet` included, is refused before the store is touched.
+That way, a task remembered from an earlier wake cannot become a delivered outcome.
+A heartbeat review is not scoped by task.
+
+The branch's guarded commands never tell it to drain queued rows mid-handling.
+For that actor, `bin/fm-guard.sh` keeps the queued-wakes warning silent.
+An acknowledgement that consumed nothing reports that plainly, with the exact command for the current wake (`docs/watcher-continuity.md` "Per-actor acknowledgement").
+
+#### Broken-branch latch and recovery
+
+1. Two consecutive settled provider errors latch the branch broken.
+   A one-line health note surfaces only on that initial trip.
+2. Main keeps every wake during a five-minute cooldown.
+3. After the cooldown, one wake may probe the branch while concurrent wakes still stay on main.
+4. Each probe that settles with another provider error doubles the next cooldown, up to one hour.
+
+A prompt from the current branch generation and model or effort selection can clear the latch.
+It must append a durable `fm_branch_report` and then settle without a provider error.
+That clears both the latch and the provider-error streak and surfaces a one-line recovery note.
+If a provider error settles after that report, the error wins instead: it re-latches the branch and extends the cooldown.
+A session replacement or branch model or effort change resets the recovery state immediately.
+
+### Branch model and effort selection
+
+The same extension registers `/supervision-model`, which picks the branch's model and then its reasoning effort.
+It applies both at the branch-session creation boundary.
+[configuration.md](configuration.md#pi-supervision-branch-model-and-effort-configsupervision-branch-model-configsupervision-branch-effort) owns the operator-facing schema and behavior.
+
+### Branch system prompt
+
+The branch system prompt comes from `bin/fm-branch-prompt.sh`.
+Its header owns the byte-stable-prefix contract (no timestamps, no fleet snapshot, no per-wake content).
+
+### Outcome store
+
+The outcome store is `bin/fm-branch-outcome.sh`.
+Its header owns the append-only format, read cursor, and bounded per-task status-coverage indexes.
+
+Outcomes are written to the store before delivery to Pi.
+A captain row advances the cursor only after its matching visible session entry exists.
+Locked session-start replay stops before the first captain row, so it cannot acknowledge that outcome through prose alone.
+
+A routine note has no such sequence-keyed record.
+If its cursor write fails after the note was delivered, the next reconciliation sends that note once more.
+That asymmetry is a known limitation of the routine delivery representation rather than of the ordering above.
+It predates delivery moving off Pi's render thread.
+Closing it means giving routine delivery a durable idempotent record.
+That work is tracked as follow-up `fm-pi-routine-delivery-idempotency-followup-r1`, and `tests/fm-pi-branch-extension.test.sh` pins that asymmetry meanwhile.
+
+### Consistency
+
+`bin/fm-lease-lib.sh` owns:
+
+- The per-task lease contract.
+- The posture-aware main-only role partition.
+- The deliberate CONFUSED-AGENT-GRADE threat model these guards target.
+  That threat model was captain-decided; adversarial-grade separation is out of scope and tracked as follow-up design work.
+
+`bin/fm-lease.sh` is the command surface.
+
+The guards are wired into these scripts:
+
+| Scripts | Guard behavior |
+| --- | --- |
+| `fm-send.sh`, `fm-control.sh`, and `fm-teardown.sh` | Overlap, lease-checked, with claim serialization retained through the mutation. |
+| `fm-pr-merge.sh`, `fm-merge-local.sh`, `fm-spawn.sh`, and `fm-send.sh --resolve-key` for a decision key | Main-owned while attended; branch refused. |
+
+A relaunch through `fm-control` stays branch-legal recovery in both postures.
+Under the away-posture record, the PR merge, a fresh spawn, and a decision answer relocate to the branch behind each script's own gate.
+Local-only landing never does ("Postures" below).
+
+### Autonomy
+
+Supervision is default-on for every task once a Pi primary session owns the fleet lock (docs/configuration.md "Pi supervision branch").
+No captain grant file is required.
+
+A fleet-wide heartbeat is separately eligible only when every row other than a check or decision-owned signal/stale row is a heartbeat row or a resolvable task-local row (see "Heartbeat routing" below).
+Every other fleet-wide or unresolvable wake, and every watcher-failure alarm, stays on main.
+
+#### Pre-drain recheck
+
+The branch recomputes eligibility immediately before prompting the branch to drain.
+It publishes the exact eligible row set to `state/.branch-eligible-rows` through `writeEligibleRowsSnapshot`.
+
+After an independently eligible wake has already been offered, a newly-arrived main-owned row observed at that pre-drain recheck does not revoke the offer.
+Instead, that row is excluded from the eligible set.
+Whatever else is currently eligible still reaches the branch, and the main-owned row stays queued for main's own drain.
+[`watcher-continuity.md`](watcher-continuity.md#per-actor-acknowledgement) owns the consume-side guarantee that neither actor can present or acknowledge the other's claim.
+
+Heartbeat keeps its own all-or-nothing recheck over the rows it can claim: it takes every branch-ownable unread row or none of them.
+An unresolvable task-local row still defers the whole review to main.
+
+A producer can still append a row in the instant between that final check and drain startup.
+This accepted residual follows the confused-agent-grade boundary above rather than claiming adversarial queue isolation.
+
+A broken branch between its bounded recovery probes keeps today's wake-to-main behavior in both postures.
+The legacy `state/.afk` daemon flag means nothing on Pi, where the daemon is never launched.
 
 ## Off-thread delivery
 
-The supervision branch lives inside the captain's own Pi process, and Pi runs extensions, their tools, and their event handlers on the single JavaScript thread that also draws the TUI and reads the keyboard.
-A synchronous subprocess in the delivery path therefore stops repaint and key echo for the child's whole lifetime, which the captain saw as a subsecond freeze every time a routine or captain-facing outcome arrived.
-Subprocess work reached through Pi's asynchronous APIs is now awaited instead: `.pi/extensions/lib/fm-async-exec.ts` owns that awaited-spawn replacement and preserves the status, captured-output, and failure semantics its callers used from the synchronous form.

+
+### The explicit delivery queue
 
 Awaiting yields the thread, so what the single thread used to guarantee for free is now an explicit queue in `.pi/extensions/fm-branch-supervision.ts`.
-Every delivery, every acknowledgement, and every turn boundary's reconciliation runs as one unit of that queue, which is what preserves the durable append before anything visible, one delivery at a time in sequence order, the read cursor advanced before the next reader sees a row, and one ownership activation per generation.
-Cancellation is preserved by the generation and lock-ownership rechecks the awaits are placed around: a session replaced mid-delivery fails the next recheck rather than acting into the session that replaced it.
+Every delivery, every acknowledgement, and every turn boundary's reconciliation runs as one unit of that queue.

+
+### Reads that stay synchronous
 
-Two reads stay synchronous because Pi's own API is synchronous there, not as an optimization.
-Pi types its bash spawn hook as a plain function, so the guard on the branch's own shell commands cannot await; and the watcher reads `offer.accepted` the moment its dispatch event returns, so a session that does not own the fleet lock must still refuse a wake without waiting.
-Both read the same uncached ownership authority: the lock's process ancestry is walked in full every time it is asked, never cached, because reparenting and pid reuse can invalidate a remembered chain and this answer decides ownership rather than hinting at it.

 ## Lost-wake outcome backstop
 
 Every main-actor wake drain checks each task's newest non-blank status event against the latest supervision-branch outcome that causally covers that task's status log.
-When that event is terminal or otherwise captain-facing and remains uncovered, the drain prints it once in `STATUS OUTCOME BACKSTOP`, even if the original queue row was already acknowledged; routine events stay silent, and valid open decisions remain owned by `OPEN DECISIONS`.
-The one-shot backstop cursor is independent from signal annotation, so a delayed signal can still present its status context without repeating the recovered event.
-The drain reads one fixed-size per-task outcome index instead of scanning append-only outcome history and inspects at most the final 64 KiB of each status log.

+It inspects at most the final 64 KiB of each status log.
+
+### Ordering limits
+
 Status provenance added to new outcome rows distinguishes covered and genuinely later events even within one timestamp second.
-Legacy outcomes predate that causal position, so equal-second migration cannot prove order and deliberately favors surfacing a plausibly later event; this can rarely duplicate an already handled legacy event.
-A pathological latest status line that crosses the 64 KiB window is unclassifiable and remains silent rather than risking presentation of routine content; this is an accepted limit, not a status-line size contract.
-A missing or invalid outcome-index ready marker is rebuilt from the authoritative outcome rows by `processed-init` under the outcome lock on the next main drain, on every harness.

 ## How the branch knows what the captain said
 
-Main's captain and assistant text - never tool calls, tool results, operational injections, or the branch's own merged notes - is mirrored into the branch as read-only `fm-main-mirror` messages.
-The idle path mirrors at main's turn end.
-At `before_agent_start`, Pi's authoritative prompt is staged verbatim before SessionManager persists that user entry, so the complete current captain message precedes any branch wake accepted after that boundary; the later persisted copy is suppressed and older dialog entries remain bounded.

+  The complete current captain message therefore precedes any branch wake accepted after that boundary.
+  The later persisted copy is suppressed, and older dialog entries remain bounded.
+
 The mirror cursor is durable (`state/.branch-mirror-cursor`), so within one main session only not-yet-mirrored dialog is replayed.
-Every main session start re-anchors the mirror to the current main session's start, because that start also opens a new branch conversation: the cursor records what the PREVIOUS branch conversation received, so without the reset a `/resume` or reload, which keeps main's own session file, would leave the new branch blind to dialog main itself still has.
-The reset is bounded by the current main session and costs only re-delivered read-only context, and the cursor keeps advancing incrementally from there.
-The branch prompt frames mirrored text as context for judgment, never as instructions addressed to the branch; an authorization addressed to main (for example "you may merge when green") does not relax the branch's role limits.

 ## Two-stage noise filter
 
 Stage one is unchanged: the bash watcher absorbs everything provably fine at zero token cost.
-Stage two is the branch's verdict on each handled event, reported through its `fm_branch_report` tool: `routine` keeps the existing custom-message path without a follow-up turn, while `captain` appends a versioned `fm-branch-visible-outcome` custom session entry.
-The captain entry contains the store sequence, task, verdict, exact summary, and silent flag, and its renderer presents the exact task and summary with an anchor prefix.
-Pi custom session entries persist in the transcript but do not enter model context, so a stale compaction summary, an unrelated assistant response, prompt caching, or model instruction noncompliance cannot acknowledge or rewrite the outcome.
-The store sequence is the idempotency key: reload after entry persistence but before cursor advancement finds the matching entry, avoids a duplicate, and advances the cursor; conflicting content for one sequence fails closed.
-Reconciliation runs at session start when that generation already owns the fleet lock and at the first post-lock `turn_end`, so a cold start that acquires the lock through the startup digest still delivers stored captain outcomes without waiting for another wake.
-Display is only half of a captain outcome; the other half is processing, because a blocker, a decision, or a ready PR needs main to act, not only the captain to see it.
-After the visible entry exists and the read cursor has passed it, the extension hands every still-unprocessed captain row to main as one hidden, typed `fm-branch-process` request (kind `branch-outcome`) listing each `[seq N] task: summary`, and that request opens exactly one main turn.
-Main closes it only by calling `fm_branch_processed` with the highest sequence the request listed, which advances a processed marker that `bin/fm-branch-outcome.sh` keeps separately from the read cursor and never moves past it or backwards.
+Stage two is the branch's verdict on each handled event, reported through its `fm_branch_report` tool:
+
+| Verdict | Delivery |
+| --- | --- |
+| `routine` | Keeps the existing custom-message path without a follow-up turn. |
+| `captain` | Appends a versioned `fm-branch-visible-outcome` custom session entry. |
+
+### The visible captain entry
+
+The captain entry contains the store sequence, task, verdict, exact summary, and silent flag.
+Its renderer presents the exact task and summary with an anchor prefix.
+
+Pi custom session entries persist in the transcript but do not enter model context.
+So a stale compaction summary, an unrelated assistant response, prompt caching, or model instruction noncompliance cannot acknowledge or rewrite the outcome.
+
+The store sequence is the idempotency key.
+A reload after entry persistence but before cursor advancement finds the matching entry, avoids a duplicate, and advances the cursor.
+Conflicting content for one sequence fails closed.
+
+Reconciliation runs at two points:
+
+- At session start, when that generation already owns the fleet lock.
+- At the first post-lock `turn_end`.
+
+Together, these let a cold start that acquires the lock through the startup digest still deliver stored captain outcomes without waiting for another wake.
+
+### Processing a captain outcome on main
+
+Display is only half of a captain outcome.
+The other half is processing, because a blocker, a decision, or a ready PR needs main to act, not only the captain to see it.
+
+1. After the visible entry exists and the read cursor has passed it, the extension hands every still-unprocessed captain row to main as one hidden, typed `fm-branch-process` request (kind `branch-outcome`).
+   The request lists each `[seq N] task: summary`.
+2. That request opens exactly one main turn.
+3. Main closes it only by calling `fm_branch_processed` with the highest sequence the request listed.
+   That call advances a processed marker, which `bin/fm-branch-outcome.sh` keeps separately from the read cursor and never moves past it or backwards.
+
 A lower listed captain sequence is accepted only as a partial acknowledgement and leaves every newer captain sequence open.
-Nothing else advances that marker: an unrelated reply, an empty reply, or a reply that paraphrases the outcome leaves the sequence unprocessed, and the extension presents the current unprocessed sequence set again at the next main run boundary and at every session start.
-A presentation already pending its run boundary is not resent or widened; once that run settles, the extension presents the then-current sequence set.
-The first two presentations of a given sequence set open a turn of their own; after that the request rides the captain's next prompt so an ignored request cannot become an unbounded loop of empty turns, while changed sequence membership and a session replacement each start that budget over.
+

+
 Routine outcomes never enter this path and stay turn-free.
 A home upgraded with outcomes already delivered treats those rows as processed once, at the first reconciliation that finds no processed marker, so its history is not re-presented.
-The generated [Pi supervision protocol](supervision-protocols/pi.md) owns event ownership for merged outcomes and main's acknowledgement duty, while deterministic entry delivery owns captain visibility.
-A no-change heartbeat outcome explicitly reported with `task=fleet` and `silent=true` is also delivered silently with no rendered note, while every other `routine` outcome stays rendered with its sailboat prefix.
-The branch prompt's "Verdict: routine or captain" section owns the verdict criteria, including how requested work's finished results and its mere progress updates are classified; unsolicited routine outcomes remain routine sailboat notes, unchanged fleet reviews remain silent, and doubt escalates.
-Its "PR identity: copy or abstain" section owns where a PR URL in a summary or tool argument may come from: the task's ready status or `pr=` metadata, verbatim, or else only the identifier the branch actually has.

 ## Heartbeat routing
 
 The cheap bash-level heartbeat scan absorbs a genuinely no-op pass before it reaches Pi, unchanged from before.
-Only a scan already flagged as possibly captain-relevant emits the bare `heartbeat` wake; `.pi/extensions/fm-primary-pi-watch.ts` flags that offer `heartbeat: true`, and the branch accepts it without a project only when every branch-ownable row observed in the unread-queue eligibility check is either heartbeat-kind or a resolvable task-local signal or stale event.

+- Heartbeat-kind.

+
+### Co-present main-owned rows
 
 A heartbeat is never vetoed or ridden into main by a co-present check row or decision-owned signal/stale row.
-Those rows are main-owned while attended: they are excluded from what the branch may claim and left queued for main, which is woken for each on its own watcher cycle, so nothing starves by being left behind; under the away-posture record the branch claims them too ("Postures" below).
-Deferring the fleet review to main merely because some unrelated merge poll or Relay mention happened to be sitting unread put a routine review in the captain's chat for a reason that had nothing to do with the fleet, and that coupling is gone.
-What all-or-nothing still guarantees is unchanged: the branch takes every branch-ownable unread row or none of them, and an unresolvable task-local row, an unknown row kind, or an unreadable queue still defers the whole review to main.

+
+### Reporting the review
+
 The branch runs its normal operating procedure for the wake (`bin/fm-branch-prompt.sh` "Handling a wake") and performs the deeper fleet review that main previously performed.
-A review that found literally nothing worth reporting uses verdict `routine`, `task=fleet`, and `silent=true` so it has no rendered note, while a fleet-wide routine action omits `silent` and keeps its rendered sailboat note.
+
+| Review result | Report |
+| --- | --- |
+| Found literally nothing worth reporting | Verdict `routine`, `task=fleet`, and `silent=true`, so it has no rendered note. |
+| A fleet-wide routine action | Omits `silent` and keeps its rendered sailboat note. |
+
 Only a captain-worthy finding reports verdict `captain` and appends a visible captain outcome entry.
-Every other fleet-wide or unresolvable wake - including watcher-failure alarms, which are never offered to the branch - keeps today's wake-to-main path in both postures.
+
+Every other fleet-wide or unresolvable wake keeps today's wake-to-main path in both postures.
+That includes watcher-failure alarms, which are never offered to the branch.
 
 ## Cost model and the byte-stable prefix
 
-The captain accepted the normal provider prompt-caching strategy: a byte-identical branch prefix generated once per firstmate version, the same tool set in the same order on every request, and one shared `prompt_cache_key` per home for all branch sessions (set in a `before_provider_request` hook, and only for providers whose requests already carry that field); main keeps its own per-session key.
-Budget roughly 60% cache hits on a new branch conversation's first call and 95% on later calls within that conversation; the shared per-home key is what carries the byte-identical prefix across the conversation each main session start opens, and reuse is best-effort, never guaranteed.
-The branch can also run on a cheaper model and a shallower reasoning effort than main, both pinned with the Pi `/supervision-model` command; [configuration.md](configuration.md#pi-supervision-branch-model-and-effort-configsupervision-branch-model-configsupervision-branch-effort) owns those pins' operator-facing schema and unpinned behavior.
-A provider an extension registered only into main's runtime, such as pi-devin-auth's `devin`, reaches the isolated branch runtime by copying its provider config from main's captured `ModelRegistry` into the branch `ModelRuntime` at model-resolution time and in the `/supervision-model` picker, so the provider's own `streamSimple` transport and OAuth wiring are reused by reference rather than reimplemented.
-That carve-out is scoped to provider registration alone: the branch keeps its `noExtensions`, `noSkills`, and `noContextFiles` isolation, the copy is never persisted, a provider whose registration fails to compose is simply unavailable, and `tests/fm-pi-branch-extension.test.sh` pins the pin-and-fallthrough behavior.
-No caching machinery beyond this exists, deliberately: any later dynamic content in the branch prefix silently removes most of the cache benefit, which is why `bin/fm-branch-prompt.sh`'s header is the contract's single owner and `tests/fm-branch-supervision.test.sh` pins the output to byte identity.
+The captain accepted the normal provider prompt-caching strategy:
+
+- A byte-identical branch prefix generated once per firstmate version.
+- The same tool set in the same order on every request.
+- One shared `prompt_cache_key` per home for all branch sessions.
+  It is set in a `before_provider_request` hook, and only for providers whose requests already carry that field.
+
+Main keeps its own per-session key.
+
+### Expected cache reuse
+
+Budget roughly 60% cache hits on a new branch conversation's first call and 95% on later calls within that conversation.
+The shared per-home key is what carries the byte-identical prefix across the conversation each main session start opens.
+Reuse is best-effort, never guaranteed.
+
+### Branch model and providers
+
+The branch can also run on a cheaper model and a shallower reasoning effort than main, both pinned with the Pi `/supervision-model` command.
+[configuration.md](configuration.md#pi-supervision-branch-model-and-effort-configsupervision-branch-model-configsupervision-branch-effort) owns those pins' operator-facing schema and unpinned behavior.
+
+Some providers are registered by an extension only into main's runtime, such as pi-devin-auth's `devin`.
+Such a provider reaches the isolated branch runtime by copying its provider config from main's captured `ModelRegistry` into the branch `ModelRuntime`.
+The copy happens at model-resolution time and in the `/supervision-model` picker.
+The provider's own `streamSimple` transport and OAuth wiring are thus reused by reference rather than reimplemented.
+
+That carve-out is scoped to provider registration alone:
+
+- The branch keeps its `noExtensions`, `noSkills`, and `noContextFiles` isolation.
+- The copy is never persisted.
+- A provider whose registration fails to compose is simply unavailable.
+
+`tests/fm-pi-branch-extension.test.sh` pins the pin-and-fallthrough behavior.
+
+### No further caching machinery
+
+No caching machinery beyond this exists, deliberately.
+Any later dynamic content in the branch prefix silently removes most of the cache benefit.
+That is why `bin/fm-branch-prompt.sh`'s header is the contract's single owner and `tests/fm-branch-supervision.test.sh` pins the output to byte identity.
 
 ## Postures
 
-One supervision session runs in two postures, attended and away, and the posture is a file: the away-posture record `state/.afk-contract`, written only by `bin/fm-afk-contract.sh` in the same turn as `/afk` and archived by the return path on the captain's first unmarked message.
-The record is never inferred from chat and never placed in the branch's byte-stable prompt prefix; the dispatcher reads its presence at every routing decision, the branch reads it at the tail of every wake and immediately before every captain-outcome presentation, and the guarded scripts validate it through the record owner at every gate.
-On Pi the away daemon is never launched, so the watcher is the single owner of supervision in both postures, and a leftover `state/.afk` flag declines nothing.

+Only `bin/fm-afk-contract.sh` writes it, in the same turn as `/afk`.
+The return path archives it on the captain's first unmarked message.
 
-While the record exists:
+### Who reads the record
 
-- Every actionable row is branch-eligible: check rows, decision-owned signal and stale rows, and heartbeat rows are claimed by the branch on whatever wake finds them unread, and the trigger class no longer forces a batch to main.
+The record is never inferred from chat and never placed in the branch's byte-stable prompt prefix.
+Three readers check it:
+
+- The dispatcher reads its presence at every routing decision.
+- The branch reads it at the tail of every wake and immediately before every captain-outcome presentation.
+- The guarded scripts validate it through the record owner at every gate.
+
+On Pi the away daemon is never launched, so the watcher is the single owner of supervision in both postures.

+### While the record exists
+
+- Every actionable row is branch-eligible.
+  Check rows, decision-owned signal and stale rows, and heartbeat rows are claimed by the branch on whatever wake finds them unread.
+  The trigger class no longer forces a batch to main.
   The two vetoes that describe a broken queue, an unresolvable task-local row and a structurally invalid row, stay vetoes in both postures.
   A prompt that claims a check row is not scoped by task, so the branch may report it as `fleet`.
-- Main is parked, and reachable only for the classes only main can act on: a watcher-failure alarm is delivered to main as always, because `fm_watch_arm_pi` lives there, and a wake the branch declines or cannot take (a broken branch inside its cooldown, an unresolvable or corrupt scan) falls back to main exactly as attended.
-  Parking is a cost and chat-cleanliness measure; supervision continuity is the safety property, and the return brief's health section reads any gap.
-- The wake message ends with a fixed `POSTURE: AWAY` tail plus the record's read-back verbatim (`bin/fm-afk-contract.sh readback`), so the branch has the captain's away words, the spend cap, the expected return, and the reach line in front of it at execution time without any prefix change.

 - Captain-verdict outcomes accumulate unprocessed in the outcome store.
-  Their visible entries still persist, but no processing turn opens on the parked main: the request is re-checked against the record immediately before it would open and at every run boundary, so a request pending when the record appears is cancelled rather than delivered.
-  The first run boundary after the record is archived, ordinarily the captain's return message, presents the accumulated rows with a fresh triggered budget exactly as after any other gap, and `bin/fm-afk-return.sh` lists them under "waiting on you".

-  The captain's away words are the whole mandate: the branch reads them at the tail, decides by its own judgment whether the event in front of it is the moment they name, acts on them only through the guarded scripts, never by analogy, and holds with verdict captain on doubt; `bin/fm-branch-prompt.sh` "Postures" owns those execution rules and requires every action taken under the words to open its outcome summary with "per your away instructions:".
-  Each relocated script keeps its own gate, enforcing exactly what a script can check without reading words: `bin/fm-pr-merge.sh` merges any pull request green at its live head, synchronously, under the record lock, and refuses `--allow-red` while away, so the green gate is absolute in this posture and which pull request the words meant is the branch's reading; `bin/fm-spawn.sh` dispatches only queued work whose blockers cleared - already queued, or filed by the branch because the words explicitly call for it - and refuses a fresh ordinary spawn for either actor once the home holds as many ordinary task records as the record's spend cap (relaunches and secondmates exempt); `bin/fm-send.sh --resolve-key` answers a decision the words pre-answer, or one `ask-user-authority`'s judgment (carried verbatim in the branch prompt) lets firstmate decide; `bin/fm-merge-local.sh` is never relocated.

+### Authority relocation
+
+`fm_lease_forbid_branch` passes the branch actor only for the actions whose guarded script opts in.
+It does so only while `bin/fm-afk-contract.sh validate` succeeds on a complete, readable, live record.
+An archived, incomplete, or invalid record restores the attended refusal byte for byte.
+

+
+- The branch reads them at the tail.
+- It decides by its own judgment whether the event in front of it is the moment they name.
+- It acts on them only through the guarded scripts, never by analogy.
+- It holds with verdict captain on doubt.
+
+`bin/fm-branch-prompt.sh` "Postures" owns those execution rules.
+It requires every action taken under the words to open its outcome summary with "per your away instructions:".
+
+Each relocated script keeps its own gate, enforcing exactly what a script can check without reading words:
+
+| Script | Gate while away |
+| --- | --- |
+| `bin/fm-pr-merge.sh` | Merges any pull request green at its live head, synchronously, under the record lock, and refuses `--allow-red` while away, so the green gate is absolute in this posture; which pull request the words meant is the branch's reading. |
+| `bin/fm-spawn.sh` | Dispatches only queued work whose blockers cleared - already queued, or filed by the branch because the words explicitly call for it; refuses a fresh ordinary spawn for either actor once the home holds as many ordinary task records as the record's spend cap (relaunches and secondmates exempt). |
+| `bin/fm-send.sh --resolve-key` | Answers a decision the words pre-answer, or one `ask-user-authority`'s judgment (carried verbatim in the branch prompt) lets firstmate decide. |
+| `bin/fm-merge-local.sh` | Never relocated. |
+
+The merge-authority record and the outcome row's summary are the audit trail.
+The return brief renders the words verbatim beside that account.
+
+### The authority invariant
+
+Being away changes how the captain is informed and what happens at a captain-owned decision point, never firstmate's authority set.
+`tests/fm-branch-supervision.test.sh`, `tests/fm-pr-merge.test.sh`, and `tests/fm-send-resolve-key.test.sh` pin this invariant.
+It sets these limits:
+
+- The never-set (credential entry, legal or financial acceptance, an attended prompt, an unnamed discard, a security-sensitive action) has no guarded entrypoint that accepts away authority for either actor.
+- A forced teardown stays refused for the branch.
+- A red merge is refused in this posture whatever the words say.
+- No relocation survives the return, because an archived record validates as absent and the words die with it.
+
+### Cleanup after a landed pull request
 
-The authority invariant, pinned by `tests/fm-branch-supervision.test.sh`, `tests/fm-pr-merge.test.sh`, and `tests/fm-send-resolve-key.test.sh`: being away changes how the captain is informed and what happens at a captain-owned decision point, never firstmate's authority set.

-The ordinary cleanup of a task whose pull request has landed needs no relocation because it is the branch's own job in both postures: `bin/fm-branch-prompt.sh` names the `check: merge landed:` wake, and any later stale or inactive-outcome row on that task, as the moment to attempt `bin/fm-teardown.sh` without `--force` and report any refusal instead of concluding there is "nothing to recover".

 # Watcher continuity
 
+This document explains how Firstmate keeps the watcher re-armed after a wake, how wakes are ordered and acknowledged, and which tests and live evidence cover that contract.
+Read it when debugging a supervision gap or changing a harness's re-arm path.
+
 The watcher remains intentionally one-shot: one actionable reason closes one watcher cycle.
 Must-work continuity now lives above that process boundary instead of depending on the model remembering a re-arm step.
+In this document, an arm is one run of `bin/fm-watch-arm.sh`, which starts a watcher cycle or attaches to one and returns the cycle's reason.
+
+| Topic | Section |
+| --- | --- |
+| Which component re-arms the watcher on each harness | [Ownership](#ownership) |
+| What happens between an actionable close and the wake reaching the model | [Actionable wake ordering](#actionable-wake-ordering) |
+| How a watcher-downtime episode is announced and retired | [Recovery episode acknowledgement](#recovery-episode-acknowledgement) |
+| How each actor consumes the wake queue | [Per-actor acknowledgement](#per-actor-acknowledgement) |
+| What `bin/fm-watch-arm.sh` guarantees about each cycle | [Arm-layer cycle contract](#arm-layer-cycle-contract) |
+| Which test suites pin these contracts | [Regression coverage](#regression-coverage) |
+| What is not guaranteed, and where live evidence lives | [Active limits and verification](#active-limits-and-verification) |
 
 ## Ownership
 
+On Pi, omp, OpenCode, Cursor, and Claude primaries, one component owns re-arming the watcher.
+Codex and Grok keep their own protocols; see [Manual recovery and other harnesses](#manual-recovery-and-other-harnesses).
+
+| Harness | Re-arm owner |
+| --- | --- |
+| Pi | `.pi/extensions/fm-primary-pi-watch.ts` |
+| omp | `.omp/extensions/fm-primary-omp-watch.ts` |
+| OpenCode | `.opencode/plugins/fm-primary-watch-arm.js` |
+| Cursor | `.cursor/hooks.json` `stop` hook (`bin/fm-turnend-guard-cursor.sh`) |
+| Claude | `.claude/settings.json` Stop `asyncRewake` hook (`bin/fm-claude-stop-autoarm.sh`) |
+
+On a non-Pi primary, a home opted into the supervision host also changes what the owner runs; see [Supervision host](#supervision-host).
+
+### Pi, omp, and OpenCode adapters
+
 Pi's `.pi/extensions/fm-primary-pi-watch.ts`, omp's `.omp/extensions/fm-primary-omp-watch.ts`, and OpenCode's `.opencode/plugins/fm-primary-watch-arm.js` own continuous re-arm after an actionable child close.
-Each adapter starts the next arm before delivering the wake prompt, checks current session-lock ownership at launch, preserves one child or scheduled retry at a time, and applies bounded exponential retry after an unexpected or failed close.
+Each adapter:
+
+- Starts the next arm before delivering the wake prompt.
+- Checks current session-lock ownership at launch.
+- Preserves one child or scheduled retry at a time.
+- Applies bounded exponential retry after an unexpected or failed close.
+
 A failed follow-up never cancels continuity restoration.
-Pi same-process session replacement follows the generation-owner contract in `.pi/extensions/fm-primary-pi-watch.ts`: `session_shutdown` changes the current generation's durable extension marker from `active` to `handoff` but keeps its established arm child alive, then the owning `session_start` publishes a distinct active generation and commits its tracked replacement arm before that arm retires the predecessor.
-A state-scoped replacement handoff carries every actionable close whose delivery overlapped `session_shutdown`, including a main follow-up Pi accepted but had not yet consumed, branch handling, and a retiring child that reports after the successor claim.
-A handoff marker never satisfies the extension-ownership tolerance, so a running Pi process whose replacement did not load this extension is reported as missing rather than borrowing stale load evidence from its predecessor.
-A main follow-up counts as delivered once Pi accepts it, never once the model reads it, because a follow-up queued while main is streaming joins the running run without a `before_agent_start`; the extension header owns how consumption is observed and why it only decides what a replacement replays.
-omp's replacement follows its own generation-owner contract in `.omp/extensions/fm-primary-omp-watch.ts`, whose header owns its differences from Pi: it retires the predecessor arm at replacement shutdown instead of retaining it across the handoff, and it reports no shutdown reason, so every shutdown with a pending actionable close persists the handoff for the next owning `session_start` to replay.
-Cursor's `.cursor/hooks.json` `stop` hook (`bin/fm-turnend-guard-cursor.sh`) owns routine tokenless re-arm for a Cursor primary by parking that awaited hook on `bin/fm-watch-arm.sh` and returning an actionable close as one follow-up; [`turnend-guard.md`](turnend-guard.md#harness-integrations) owns its Pi-host stand-down, loop bounds, and supersession baton.

+Pi same-process session replacement follows the generation-owner contract in `.pi/extensions/fm-primary-pi-watch.ts`:
+
+1. `session_shutdown` changes the current generation's durable extension marker from `active` to `handoff`, but keeps its established arm child alive.
+2. The owning `session_start` publishes a distinct active generation.
+3. That `session_start` commits its tracked replacement arm.
+4. Only after that commit does the replacement arm retire the predecessor.
+
+A state-scoped replacement handoff carries every actionable close whose delivery overlapped `session_shutdown`, including:
+
+- A main follow-up Pi accepted but had not yet consumed.
+- Branch handling.
+- A retiring child that reports after the successor claim.
+
+A handoff marker never satisfies the extension-ownership tolerance.
+So a running Pi process whose replacement did not load this extension is reported as missing, rather than borrowing stale load evidence from its predecessor.
+
+A main follow-up counts as delivered once Pi accepts it, never once the model reads it.
+The reason is that a follow-up queued while main is streaming joins the running run without a `before_agent_start`.
+The extension header owns how consumption is observed and why it only decides what a replacement replays.
+
+### omp session replacement
+
+omp's replacement follows its own generation-owner contract in `.omp/extensions/fm-primary-omp-watch.ts`, whose header owns its differences from Pi:
+
+- It retires the predecessor arm at replacement shutdown instead of retaining it across the handoff.
+- It reports no shutdown reason, so every shutdown with a pending actionable close persists the handoff for the next owning `session_start` to replay.
+
+### Cursor stop hook
+
+Cursor's `.cursor/hooks.json` `stop` hook (`bin/fm-turnend-guard-cursor.sh`) owns routine tokenless re-arm for a Cursor primary.
+It re-arms by parking that awaited hook on `bin/fm-watch-arm.sh` and returning an actionable close as one follow-up.
+[`turnend-guard.md`](turnend-guard.md#harness-integrations) owns its Pi-host stand-down, loop bounds, and supersession baton.
+
+### Claude Stop hook
+
 Claude's `.claude/settings.json` Stop `asyncRewake` hook (`bin/fm-claude-stop-autoarm.sh`) owns routine tokenless re-arm.
-The hook fires on every Stop, and an eligible primary with supervision need admits one home-scoped owner that foregrounds `bin/fm-watch-arm.sh` inside the hook-owned process tree.
-A numeric session-lock owner that fails the shared `fm_harness_pid_alive` predicate is reclaimed through `bin/fm-lock.sh` before auto-arm state changes, while a live owner the session does not own, an absent lock, or a malformed lock keeps the competing hook inert.
-Whether the session owns that lock is the shared `fm_session_lock_owned_by_self` verdict in `bin/fm-session-lock-lib.sh`, which accepts a recorded pid inside the current harness ancestry or a live lock recorded under this same trusted Claude session id, so a background session keeps arming after its transient helper chain is recycled.
+The hook fires on every Stop.
+On each Stop, an eligible primary with supervision need admits one home-scoped owner, which foregrounds `bin/fm-watch-arm.sh` inside the hook-owned process tree.
+While supervision is still needed and away mode remains inactive, an actionable close wakes the idle session through exit 2.
+
+### Claude session-lock ownership
+
+The hook handles the session lock as follows:
+
+- A numeric session-lock owner that fails the shared `fm_harness_pid_alive` predicate is reclaimed through `bin/fm-lock.sh` before auto-arm state changes.
+- A live owner the session does not own, an absent lock, or a malformed lock keeps the competing hook inert.
+
+Whether the session owns that lock is the shared `fm_session_lock_owned_by_self` verdict in `bin/fm-session-lock-lib.sh`.
+That verdict accepts either of two cases:
+
+- A recorded pid inside the current harness ancestry.
+- A live lock recorded under this same trusted Claude session id.
+
+With that verdict, a background session keeps arming after its transient helper chain is recycled.
 [`turnend-guard.md`](turnend-guard.md#guard-predicates) owns the Claude guard's behavior when that live owner is genuinely another session.
 The stale-owner claim occurs only after the existing AFK and supervision-need gates pass.
+
+### Claude arm failures
+
 After each non-actionable arm close, the hook rechecks the identity-matched watcher lock and fresh beacon before retrying a bounded number of times.
-A cycle-end failure is benign when that live-watcher predicate is true, and the hook suppresses the arm output and continues silently.
-Only an exhausted failure with no verified watcher commits one last-resort notice for the continuous failure episode; a refused notice commit stays silent for a later retry, and after a successful notice later Stop cycles exit 2 without repeating it until the turn-end guard consumes the attended fail-open.
+The beacon is `state/.last-watcher-beat`, which only the watcher process touches.
+
+- A cycle-end failure is benign when that live-watcher predicate is true.
+  In that case the hook suppresses the arm output and continues silently.
+- Only an exhausted failure with no verified watcher commits one last-resort notice for the continuous failure episode.
+- A refused notice commit stays silent for a later retry.
+- After a successful notice, later Stop cycles exit 2 without repeating it until the turn-end guard consumes the attended fail-open.
+
 The Claude turn-end guard owns that notice commit contract, the monotonic failure progression, one-time attended fail-open, post-alarm continuation suppression, and positive recovery reset described in [`turnend-guard.md`](turnend-guard.md#harness-integrations).
-While supervision is still needed and away mode remains inactive, an actionable close wakes the idle session through exit 2.
-A home opted into the supervision host runs `bin/fm-supervision-host.sh` in that arm's place; it owns successive watcher cycles through the same arm, starts and confirms each successor before its engine handles an away wake, and stops its cycle before handing a wake back, so the recovery and acknowledgement contracts below apply unchanged ([supervision-host.md](supervision-host.md)).
+
+### Supervision host
+
+On a non-Pi primary, a home opted into the supervision host runs `bin/fm-supervision-host.sh` in place of the arm its re-arm owner would start.
+The host owns successive watcher cycles through the same arm.
+It starts and confirms each successor before its engine handles an away wake, and it stops its cycle before handing a wake back.
+So the recovery and acknowledgement contracts below apply unchanged ([supervision-host.md](supervision-host.md)).
 
 ## Actionable wake ordering
 
-After an actionable Pi, omp, or OpenCode child close, the adapter waits for the predecessor process to close, then starts and verifies one singleton successor before it delivers the original wake.
-A complete Pi reason line observed while the predecessor is still finishing durable cleanup is retained for replacement handoff but never treats that already-ready predecessor as its own successor.
-It confirms the handling handoff against that successor before scheduling the follow-up, retries once against the current generation and successor, and treats a failed confirmation as a restoration failure: it classifies the error, retires a successor that is no longer alive, and surfaces exactly one typed message.
+This section covers what each re-arm owner does between an actionable close and the wake reaching the model.
+
+### Pi, omp, and OpenCode successor start
+
+After an actionable Pi, omp, or OpenCode child close, the adapter:
+
+1. Waits for the predecessor process to close.
+2. Starts and verifies one singleton successor.
+3. Confirms the handling handoff against that successor before scheduling the follow-up.
+4. Delivers the original wake.
+
+A complete Pi reason line can be observed while the predecessor is still finishing durable cleanup.
+That line is retained for replacement handoff, but the adapter never treats that already-ready predecessor as its own successor.
+
+If the handoff confirmation fails, the adapter retries it once against the current generation and successor.
+A failed confirmation is a restoration failure: the adapter classifies the error, retires a successor that is no longer alive, and surfaces exactly one typed message.
 A failed confirmation is never swallowed.
-It waits at most one readiness timeout per attempt, then sends TERM and waits a bounded retirement confirmation before the next lock-verified exponential retry.
+
+### Readiness timeout and retry
+
+The adapter waits at most one readiness timeout per attempt.
+If the successor is not ready in that time, the adapter sends TERM and waits a bounded retirement confirmation before the next lock-verified exponential retry.
+
 If the unready arm does not retire within that bound, the adapter keeps ownership, starts no overlapping retry, and delivers the typed fallback immediately.
 When that retained arm later closes, its actual close is classified as a new supervised event without replaying the earlier fallback.
-After the configured retry bound is exhausted, it delivers the original wake with a typed continuity-restoration failure even if every successor arm hung without reporting readiness.
-This is deliberate Option B ordering: the fleet is protected before the model handles the wake whenever restoration succeeds, but the model is never left blind when it does not.
+After the configured retry bound is exhausted, the adapter delivers the original wake with a typed continuity-restoration failure, even if every successor arm hung without reporting readiness.
+
+This is deliberate Option B ordering.
+Whenever restoration succeeds, the fleet is protected before the model handles the wake.
+When restoration does not succeed, the model is never left blind.
+
+### Claude handling successor
+
+Claude's Stop hook also starts one handling successor before notification.
+After an actionable foreground close, including an attached peer cycle that ended, the hook:
+
+1. Launches `bin/fm-watch-arm.sh` with the closed arm's pid as `FM_WATCH_PREDECESSOR_ARM_PID`.
+2. Waits for that arm's one status line.
+3. Only then exits 2 with the wake.
+
+A child of the hook cannot outlive its exit-2 rewake.
+So that successor is the one deliberate detached launch in the continuity path:
+
+- It runs under nohup.
+- Its stdio is away from the hook's pipes.
+- It has its own process group.
+
+This is the shape `bin/fm-startup-network.sh` uses, and [`verification/supervision.md`](verification/supervision.md#detached-session-open-workers-survive-the-hook) verified that it survives the hook.
+
+The next Stop's foreground arm attaches to that live cycle.
+A successor that confirms no live watcher adds one line to the rewake banner and never withholds the wake.
+The next Stop then re-arms as before.
+
+### Durable queue and turn-end backstop
+
+The durable wake queue preserves actionable events between a watcher close and the next drain.
+The bounded turn-end guard enforces recovery at Stop when no watcher is live and no open generation claim is still deciding.
+So a finished, hung, or identity-mismatched claim cannot suppress that recovery ([`turnend-guard.md`](turnend-guard.md#harness-integrations) owns that boundary).
 
-Claude's Stop hook also starts one handling successor before notification: after an actionable foreground close, including an attached peer cycle that ended, it launches `bin/fm-watch-arm.sh` with the closed arm's pid as `FM_WATCH_PREDECESSOR_ARM_PID`, waits for that arm's one status line, and only then exits 2 with the wake.

-The next Stop's foreground arm attaches to that live cycle; a successor that confirms no live watcher adds one line to the rewake banner and never withholds the wake, leaving the next Stop to re-arm as before.
-The durable wake queue preserves actionable events between a watcher close and the next drain, and the bounded turn-end guard enforces recovery at Stop when no watcher is live and no open generation claim is still deciding, so a finished, hung, or identity-mismatched claim cannot suppress it ([`turnend-guard.md`](turnend-guard.md#harness-integrations) owns that boundary).
 The recovery-episode contract below owns once-per-generation announcement.
-A handling successor does not re-announce; it enters its poll loop immediately and keeps scanning signals, stale panes, and checks.
-The model no longer re-arms after ordinary wakes.
-No PreToolUse hook denies fleet commands based on watcher status.
-A genuine auto-arm failure describes the automatic mechanism as broken and never directs a routine manual background arm.
-Terminal arm-output classification (`started`, `attached`, or `FAILED`) remains defense in depth for the manual recovery path.
-Codex retains its bounded foreground checkpoint protocol.
-Grok retains its tracked background-task notification protocol.
-No adapter starts a replacement with a fire-and-forget shell `&` from a model command; the Claude hook's detached handling successor is launched by the hook itself, which waits for the successor's status line before it exits.

 ## Recovery episode acknowledgement
 
-A recovery episode is one generation of `state/.watcher-down`, and it is retired only by the generation-bound acknowledgement the drain prints as `WAKE_ACK_REQUIRED`.
-An unacknowledged downtime generation is announced at most once: the first recovery marks that generation announced, and later arms wait until a new down stretch mints a new generation.
-A non-successor watcher start after an announced-but-unacked episode is a new down stretch and mints a fresh generation so buried decisions still resurface once.
-Every watcher close and every durable queue append publishes downtime, so a downtime republication of any pending episode reuses its generation instead of minting a new one, and an already-announced generation stays announced.
-That reuse keeps a watcher close inside the handling window from orphaning the acknowledgement already presented and trapping later arms in repeated recovery presentation.
-An acknowledgement carries two separable facts: queue-row consumption is bound to the monotonic `--ack-through` sequence (further scoped per actor - see "Per-actor acknowledgement" below), while only retiring the episode is bound to `--recovery-generation`.
-A generation mismatch therefore does not block consumption of rows through that sequence; it is a non-fatal result that names its own remedy - re-drain, then acknowledge the newer episode.

+
+An acknowledgement carries two separable facts:

+- Only retiring the episode is bound to `--recovery-generation`.
+
+A generation mismatch therefore does not block consumption of rows through that sequence.
+It is a non-fatal result that names its own remedy: re-drain, then acknowledge the newer episode.
+
 The acknowledgement retires the marker only when no rows remain after sequence-bound consumption.
 A concurrently appended wake has a higher sequence, remains queued, and keeps the episode pending for presentation.
 Consequently, an empty-queue downtime publication during handling can be retired by the outstanding acknowledgement without a dedicated recovery turn.

+
+### Claiming rows
+
 Every presented row is claimed to exactly one actor under the durable queue lock.
+
+- Main records its presented set in `state/.main-eligible-rows`.
+- A branch grant is published through `bin/fm-wake-grant.sh` under that same lock in `state/.branch-eligible-rows`.
+  The grant is bound to the live branch process and extension generation recorded in `state/.branch-eligible-owner`.
+  Publication is refused if main already claimed any requested row.
+- A main drain validates that owner evidence under the queue lock and reclaims the grant when its process is gone or its identity no longer matches.
+- A main drain claims every currently unclaimed row and excludes an active branch grant from both presentation and acknowledgement.
+
+### Lock deadlines during presentation
+
 An ordinary presentation drain bounds both its initial queue-lock acquire and its later status-presentation-lock acquire at the deadline owned by the script header.
-A live initial queue-lock holder produces one PID-naming advisory and skips the whole drain before any claim or mutation, while a live status-presentation-lock holder produces one such advisory after raw wake presentation and leaves status annotations, sections, and cursors retriable on the next drain.
+
+| Lock with a live holder | Drain result |
+| --- | --- |
+| Initial queue lock | One PID-naming advisory, and the whole drain is skipped before any claim or mutation. |
+| Status-presentation lock | One such advisory after raw wake presentation, and status annotations, sections, and cursors are left retriable on the next drain. |
+
 Acknowledgement invocations and every other mutation-critical queue-lock acquire retain blocking semantics, so acknowledgement atomicity is unchanged.
-Main records its presented set in `state/.main-eligible-rows`.
-A branch grant is published through `bin/fm-wake-grant.sh` under that same lock in `state/.branch-eligible-rows`, bound to the live branch process and extension generation recorded in `state/.branch-eligible-owner`, and publication is refused if main already claimed any requested row.
-A main drain validates that owner evidence under the queue lock and reclaims the grant when its process is gone or its identity no longer matches.
-A main drain claims every currently unclaimed row and excludes an active branch grant from both presentation and acknowledgement.
-Because that exclusion makes those rows invisible to main, `bin/fm-guard.sh`'s queued-wake warning counts only the rows the calling actor can itself present or retire, so an actor is never sent to a drain that provably has nothing for it.
+
+### Guard counts for branch-held rows
+
+Because the main drain's exclusion makes branch-granted rows invisible to main, `bin/fm-guard.sh`'s queued-wake warning counts only the rows the calling actor can itself present or retire.
+So an actor is never sent to a drain that provably has nothing for it.
 `bin/fm-wake-lib.sh` owns that per-actor count (`fm_wake_actor_pending_count`) alongside the grant row-list and owner-record reads that the drain and `bin/fm-wake-grant.sh` share.
-A row a live grant reserves is therefore never counted as drainable for main; rather than going silent about a visibly non-empty queue, the guard prints a distinct advisory naming the live supervision branch as the holder and saying not to drain those rows from here.

+Rather than going silent about a visibly non-empty queue, the guard prints a distinct advisory.
+That advisory names the live supervision branch as the holder and says not to drain those rows from here.
+
 The branch actor's queued-wake output stays suppressed in every case.
 A main drain with nothing of its own left, and a live grant still holding the queue, says so in one bounded line instead of exiting silently.
-A row that lost the five appended fields or its numeric sequence can never be claimed, presented, or named by an `--ack-through` cutoff, so a main drain retires it under the queue lock and reports how many it removed together with those rows verbatim, bounded to the first 20 and a count of the rest, because the queue was their only durable record; a branch drain never does, because a grant can only name sequences that were structurally valid when it was published.
-A retirement that cannot be read or written is reported and never fails the drain: the rows that remain usable are still presented with their acknowledgement command, the unusable ones stay queued for a later drain to retire, and failing the whole drain would strand the usable rows too.
-Its `--ack-through <SEQ>` deletes only claimed main rows at or below the cutoff, while a branch acknowledgement deletes only claimed branch rows at or below its cutoff.
-A main acknowledgement first claims every unreserved row at or below its cutoff, so none is stranded, and leaves a row above the cutoff that arrived after presentation unowned, so an away-session grant can still take it rather than handing every later wake back to main.
-Every settled branch prompt releases any residual grant, so an omitted or failed acknowledgement leaves the durable row available to a later main drain; a successful acknowledgement has already removed it.
-An acknowledgement whose cutoff removes none of the actor's rows while a presented row above the cutoff still waits is reported as having acknowledged nothing, together with the exact `--ack-through` and `--recovery-generation` command for that presented row; the presented set is read before any re-claim, so a row that arrived after presentation is never named for unseen acknowledgement.
+
+### Structurally unusable rows
+
+A row that lost the five appended fields or its numeric sequence can never be claimed, presented, or named by an `--ack-through` cutoff.
+A main drain retires such a row under the queue lock.
+It reports how many it removed, together with those rows verbatim, bounded to the first 20 and a count of the rest, because the queue was their only durable record.
+A branch drain never retires them, because a grant can only name sequences that were structurally valid when it was published.
+
+A retirement that cannot be read or written is reported and never fails the drain.
+The rows that remain usable are still presented with their acknowledgement command, and the unusable ones stay queued for a later drain to retire.
+Failing the whole drain would strand the usable rows too.
+
+### Acknowledgement cutoffs
+
+| Acknowledgement | What it deletes |
+| --- | --- |
+| Main `--ack-through <SEQ>` | Only claimed main rows at or below the cutoff. |
+| Branch | Only claimed branch rows at or below its cutoff. |
+
+A main acknowledgement first claims every unreserved row at or below its cutoff, so none is stranded.
+It leaves a row above the cutoff that arrived after presentation unowned, so an away-session grant can still take it rather than handing every later wake back to main.
+
+Every settled branch prompt releases any residual grant.
+So an omitted or failed acknowledgement leaves the durable row available to a later main drain.
+A successful acknowledgement has already removed it.
+
+An acknowledgement can remove none of the actor's rows while a presented row above the cutoff still waits.
+Such an acknowledgement is reported as having acknowledged nothing, together with the exact `--ack-through` and `--recovery-generation` command for that presented row.
+The presented set is read before any re-claim, so a row that arrived after presentation is never named for unseen acknowledgement.
+
 If a branch offer loses the claim race to main, it rejects its settlement so the watcher retains the actionable close until Pi accepts its main follow-up.
+
+### Branch eligibility and check rows
+
 [`pi-supervision-branch.md`](pi-supervision-branch.md#components-and-their-owners) owns branch eligibility, mixed-queue dispatch, the pre-drain recheck, and heartbeat's all-or-nothing rule.
-A check-kind row is main-owned in every mode, including a heartbeat review, so it is never part of a branch claim and never defers one; main is woken for it on that check's own triggering close.
-`fm-wake-drain.sh` never reclassifies a row itself: it filters the queue to the current actor's opaque claim before same-key deduplication, then presents and acknowledges only that actor-local view.

 A missing or empty branch snapshot is refused loudly rather than read as "nothing eligible", because reaching the drain without the non-empty handoff promised by the extension is a wiring bug.
 Because branch claims contain no check-kind rows, a branch acknowledgement skips check-specific receipt scans.
-`tests/fm-wake-queue.test.sh`'s mixed-queue actor, stale-acknowledgement remedy, and presentation-deadline tests drive the real scripts: branch acknowledgement cannot swallow a main row, a concurrent main turn cannot present or acknowledge an active branch grant, a no-op stale acknowledgement names the current presented wake's exact command, live-holder presentation contention stays bounded and retriable, and acknowledgement locking remains blocking.
-The same suite pins the counted-equals-presentable invariant against `bin/fm-guard.sh` and `bin/fm-wake-drain.sh` together: a branch-held row raises the held advisory rather than the ordinary queued-wake warning for main, and is presented with its acknowledgement command - with the ordinary warning restored - as soon as the grant clears, and structurally unusable rows are retired by main alone while every remaining row stays presentable and acknowledgeable.

 ## Arm-layer cycle contract
 
 `bin/fm-watch-arm.sh` never returns a clean empty success.
-An actionable child output returns that reason normally.
-A zero/empty child return rechecks the home lock and beacon, attaches to a verified healthy successor when one exists, or resolves the close against the watcher's bounded terminal-delivery ledger.
-An attached arm follows verified identity-matched successors and resolves the same way when that chain ends without one, because it holds no handle on the watcher's stdout and cannot read the reason line itself.

+
+An attached arm follows verified identity-matched successors and resolves the same way when that chain ends without one.
+It does this because it holds no handle on the watcher's stdout and cannot read the reason line itself.
+
+### Terminal-delivery ledger
+
 Before releasing its singleton lock after printing an actionable reason, the watcher records that reason with its PID and process identity in `state/.watch-deliveries.log`.
-A matching PID and identity lets an attached arm report the delivered reason and exit zero even after its durable wake was handled and acknowledged, while an unrelated queue producer or a recycled PID cannot satisfy the match.
+A matching PID and identity lets an attached arm report the delivered reason and exit zero, even after its durable wake was handled and acknowledged.
+An unrelated queue producer or a recycled PID cannot satisfy the match.
 Only a cycle with no matching delivery record emits `watcher: FAILED - cycle ended without an actionable reason` and exits nonzero.
 
+### Cycle exit log
+
 The arm layer appends one tab-separated record per observed cycle to `state/.watch-cycle-exits.log`.
-Each record includes arm and watcher PIDs, start and end timestamps, exit code and signal, classified reason, beacon age, lock identity before and after close, and successor disposition.
+Each record includes:
+
+- Arm and watcher PIDs.
+- Start and end timestamps.
+- Exit code and signal.
+- Classified reason.
+- Beacon age.
+- Lock identity before and after close.
+- Successor disposition.
+
 The file is size-capped through `FM_WATCH_CYCLE_LOG_MAX_BYTES` and `FM_WATCH_CYCLE_LOG_KEEP_LINES`.
 `state/.watch-triage.log` remains only the watcher's bounded absorbed-wake debug log and carries no lifecycle semantics.
 
+### Grace, beacon, and stop signals
+
 The default 300-second grace is unchanged.
-Only the watcher process touches `state/.last-watcher-beat`; no helper process can make a wedged watcher appear healthy.
-The watcher uses bash's native fatal handling for HUP and TERM, including during a blocked poll, so both run its EXIT cleanup; `watcher_stop_signals` in `bin/fm-watch.sh` owns the signal-handling rationale.

 ## Regression coverage
 
-`tests/fm-pi-watch-extension.test.sh` checks Pi's first-cycle-or-explicit-repair tool metadata and ownership-based redundant-call no-ops, then simulates actionable and empty child closes against the actual Pi and OpenCode close handlers, blocks prompt delivery to prove the successor launches first, verifies single-flight behavior, changes the session lock before close to prove ownership is rechecked, and hangs each successor arm to prove bounded fallback delivery includes the typed restoration failure.
-The same suite covers ordinary same-process session replacement for `/new`, `/resume`, `/fork`, and reload, same-instance shutdown-plus-start, the predecessor remaining live under a handoff generation until its replacement commits, bounded retry after that replacement kills the predecessor but fails before readiness, automatic re-arm before any model turn, a fresh extension-module rebind carrying all in-flight actionable closes exactly once, stale prior-generation callbacks, repeated transitions with exactly one live cycle, disappearance of the shutting-down refusal after a valid replacement activates, and terminal quit still refusing late rearm.
-The guard and session-start suites prove that active generation evidence tolerates a fresh-beacon handoff while a legacy or handoff-phase watcher marker from an absent replacement extension still raises the outage diagnostic.
-`tests/fm-watch-arm.test.sh` covers durable queue replay, real remote parent-replies ingestion into the authoritative status log, decision-only OPEN DECISIONS recovery, interrupted handling replay, generation-bound acknowledgement, a persistent live successor after recovery, a watcher close inside the handling window that must leave the printed acknowledgement valid, a re-arm whose recovery cycle is slowed after confirmation and must still surface rather than read as a watcher that stayed live, and the self-healing moved-generation acknowledgement that consumes its handled rows and names its remedy.
-`tests/fm-watch-recovery-loop.test.sh` covers the once-per-generation announcement bound with the real Pi extension against a refused handling handshake, and a handling successor that must surface a real crew event instead of going blind.
+### Pi and OpenCode watch extension
+
+`tests/fm-pi-watch-extension.test.sh` checks Pi's first-cycle-or-explicit-repair tool metadata and ownership-based redundant-call no-ops.
+It then simulates actionable and empty child closes against the actual Pi and OpenCode close handlers, and:
+
+- Blocks prompt delivery to prove the successor launches first.
+- Verifies single-flight behavior.
+- Changes the session lock before close to prove ownership is rechecked.
+- Hangs each successor arm to prove bounded fallback delivery includes the typed restoration failure.
+
+The same suite covers ordinary same-process session replacement for `/new`, `/resume`, `/fork`, and reload, plus:
+
+- Same-instance shutdown-plus-start.
+- The predecessor remaining live under a handoff generation until its replacement commits.
+- Bounded retry after that replacement kills the predecessor but fails before readiness.
+- Automatic re-arm before any model turn.
+- A fresh extension-module rebind carrying all in-flight actionable closes exactly once.
+- Stale prior-generation callbacks.
+- Repeated transitions with exactly one live cycle.
+- Disappearance of the shutting-down refusal after a valid replacement activates.
+- Terminal quit still refusing late rearm.
+
+The guard and session-start suites prove that active generation evidence tolerates a fresh-beacon handoff.
+They also prove that a legacy or handoff-phase watcher marker from an absent replacement extension still raises the outage diagnostic.

+### Arm, recovery, triage, and lock suites
+
+`tests/fm-watch-arm.test.sh` covers:

+- A persistent live successor after recovery.
+- A watcher close inside the handling window that must leave the printed acknowledgement valid.
+- A re-arm whose recovery cycle is slowed after confirmation and must still surface rather than read as a watcher that stayed live.
+- The self-healing moved-generation acknowledgement that consumes its handled rows and names its remedy.
+
+`tests/fm-watch-recovery-loop.test.sh` covers:
+
+- The once-per-generation announcement bound with the real Pi extension against a refused handling handshake.
+- A handling successor that must surface a real crew event instead of going blind.
+
 `tests/fm-watch-triage.test.sh` proves TERM stops a watcher blocked inside a poll's pane capture and still releases its lock and records an acknowledgeable stop.
 It also checks that a newly appended keyed decision is classified without rereading earlier status bytes, so signal handling can return to the watcher's beacon refresh even when the status history is long.
-`tests/fm-watcher-lock.test.sh` covers verified-successor attach, recovery publication before stale-lock removal, the typed self-eviction failure, bounded and successor-linked lifecycle rows, and a SIGSTOP counterfactual that distinguishes a live PID from a stale beacon before classifying termination.

 ## Active limits and verification
 
 The goal is continuity without a Pi, omp, or OpenCode model-memory re-arm step.
-No zero-latency guarantee is claimed because lock verification, watcher startup, and bounded retry delays remain deliberate safety work.

* docs: make sessionstart-nudge easier to read

Restructure the prose into sections, lists, and tables without changing documented behavior. Every original heading, inline-code span, link target, number, and fact is preserved, and a harness-to-tier table now sits near the top.

* no-mistakes(review): Drop helm glossary line and dedupe exit-code lead-in

 # Native session-start adapters
 
+This doc is for operators who need to know which harnesses run `bin/fm-session-start.sh` when a session opens, which only nudge the agent to run it, and how clear, compaction, and resume are handled.
 AGENTS.md section 3 is the authoritative behavioral contract for session start.
 This file owns how the tracked native session-open adapters deliver it, and the compatibility limits that force two tiers rather than one.
 
-Firstmate ships two session-open tiers, and the tier is a property of the harness surface, not of the home.
+One term recurs throughout:
+
+- The digest is the ordered startup report that `bin/fm-session-start.sh` prints.

+### Why the run tier exists
+
 The run tier exists because the nudge can only ask.
 An agent can defer an instruction, including when a first-command skill has its own read-only path.
 Running the digest through the native adapter removes that discretion, so even a session whose first command is a skill has already taken the helm.
-The nudge tier remains the floor for harnesses that cannot carry hook stdout into model context, and it is never a second contract: both tiers end in the same `bin/fm-session-start.sh`.

-It takes `--source <name>` when the adapter knows the source natively, and otherwise reads the `source` field from a Claude/Codex-shaped JSON hook payload on stdin.
+`bin/fm-sessionstart-run.sh` is the single owner of what a session-open source means.
+Because of that, no harness matcher string has to encode that policy.
+The run wrapper learns the source in one of two ways:
+
+- It takes `--source <name>` when the adapter knows the source natively.
+- Otherwise it reads the `source` field from a Claude/Codex-shaped JSON hook payload on stdin.
+
+A re-emit (`--reemit`) reprints the digest for a process that already has the helm and lost only its context.

+
+- Compaction is covered where a tracked adapter delivers that source, because a compacted session has lost exactly the digest it needs.
+- Resume is excluded from the run because it restores that digest instead of losing it.
+
+### Lock and completion interlock
 
-Current harness ownership of the lock and its matching `state/.session-start-complete` record together are the idempotency interlock for the whole scheme.
-The full digest clears that completion record after acquiring the lock and republishes the lock owner's pid only after every stage completes, so `clear` or `compact` cannot skip startup sweeps after a truncated run.
-`bin/fm-lock.sh` treats a lock owned through either the shared ancestry verdict or a trusted same-session Claude id as this session's own, so a proven `clear` or `compact` re-emit re-verifies ownership and proceeds, while a lock another live session took meanwhile still produces the ordinary read-only digest.
-On a run-tier harness only `resume`, `reload`, and `fork` are routed to the nudge wrapper, whose separate ancestry-only check normally stays silent when this process already holds the lock.
-After a background Claude helper-chain recycle breaks that ancestry, the wrapper may emit a redundant nudge even though the shared same-session verdict still owns the lock; the requested session start remains idempotent.
+Two records together are the idempotency interlock for the whole scheme:
 
-`bin/fm-session-start.sh --reemit` owns which work a re-emit skips, its true-start AGENTS.md baseline, and its supported stale-instruction refresh pairs; its header is the single owner of those mechanics.
+- Current harness ownership of the lock.
+- Its matching `state/.session-start-complete` record.
+
+The full digest updates the completion record in this order:
+
+1. It acquires the lock.
+2. It clears the completion record.
+3. It republishes the lock owner's pid only after every stage completes.
+
+So `clear` or `compact` cannot skip startup sweeps after a truncated run.
+
+`bin/fm-lock.sh` treats a lock as this session's own when it is owned through either of these:
+
+- The shared ancestry verdict.
+- A trusted same-session Claude id.
+
+So a proven `clear` or `compact` re-emit re-verifies ownership and proceeds.
+A lock another live session took meanwhile still produces the ordinary read-only digest.

+On a run-tier harness, only `resume`, `reload`, and `fork` are routed to the nudge wrapper.
+The nudge wrapper has its own separate ancestry-only check, which normally stays silent when this process already holds the lock.
+A background Claude helper-chain recycle can break that ancestry.
+The wrapper may then emit a redundant nudge even though the shared same-session verdict still owns the lock.
+The requested session start remains idempotent.
+
+### Re-emit mechanics
+
+`bin/fm-session-start.sh --reemit` owns these re-emit details:
+
+- Which work a re-emit skips.
+- Its true-start AGENTS.md baseline.
+- Its supported stale-instruction refresh pairs.
+
+The `bin/fm-session-start.sh` header is the single owner of those mechanics.
 
 ## Runtime bound
 
-The run tier blocks either hook-driven session initialization or Pi's first provider preflight while the digest runs, so `bin/fm-session-start.sh` bounds itself rather than betting on an unbounded prerequisite.
-The digest makes no external-network call at all: every one it owes runs off the blocking path in the separately bounded deferred stage owned by `bin/fm-startup-network.sh`, so an unreachable host can no longer consume this budget.
-Tool version probes, the backlog listing, and the per-task endpoint reads remain local but unbounded subprocesses, so the whole digest still runs as one bounded child, default 120s via `FM_SESSION_START_TIMEOUT`.
-The per-item backlog row reads inside bootstrap's reconcile and close-replay sweeps are the exception: each is bounded by `FM_BACKLOG_ROW_TIMEOUT_SECS` (default 10s) through `bin/fm-backlog-transition-lib.sh`, and the first bound hit latches the sweep so later reads return immediately while still naming their own item.
-The shared timeout owner falls back to a pure-Bash process-group watchdog when timeout, gtimeout, and perl are unavailable, so no supported host runs the digest unbounded.
-Because the child streams into the native transport as it runs, everything emitted before the bound was hit is retained for delivery; the parent then prints a `STARTUP TRUNCATED` banner naming the stage that did not finish and the stages that were therefore never emitted, and still exits 0.
-The registered hook timeouts sit above that budget so the harness never preempts the banner.
-The deferred startup stage deliberately runs in its own process group under its own deadline, so a truncated digest neither kills the network checks and inactive-outcome scan it was not waiting for nor orphans unbounded network work.
+While the digest runs, the run tier blocks one of two things:
+
+- Hook-driven session initialization.
+- Pi's first provider preflight.
+
+So `bin/fm-session-start.sh` bounds itself rather than betting on an unbounded prerequisite.
+
+### Network work stays off the blocking path
+
+The digest makes no external-network call at all.
+Every network call it owes runs off the blocking path, in the separately bounded deferred stage owned by `bin/fm-startup-network.sh`.
+So an unreachable host can no longer consume this budget.
+
+### Digest timeout
+
+Some digest work remains local but unbounded:
+
+- Tool version probes.
+- The backlog listing.
+- The per-task endpoint reads.
+
+So the whole digest still runs as one bounded child, default 120s via `FM_SESSION_START_TIMEOUT`.
+
+The per-item backlog row reads inside bootstrap's reconcile and close-replay sweeps are the exception.
+Each of those reads is bounded by `FM_BACKLOG_ROW_TIMEOUT_SECS` (default 10s) through `bin/fm-backlog-transition-lib.sh`.
+The first bound hit latches the sweep.
+Later reads in that sweep then return immediately while still naming their own item.
+
+When timeout, gtimeout, and perl are unavailable, the shared timeout owner falls back to a pure-Bash process-group watchdog.
+So no supported host runs the digest unbounded.
+
+### When the bound is hit
+
+The child streams into the native transport as it runs.
+So everything emitted before the bound was hit is retained for delivery.
+The parent then prints a `STARTUP TRUNCATED` banner that names:
+
+- The stage that did not finish.
+- The stages that were therefore never emitted.
+
+The parent still exits 0.
+The registered hook timeouts sit above that budget, so the harness never preempts the banner.
+
+The deferred startup stage deliberately runs in its own process group under its own deadline.
+So a truncated digest does neither of these:
+
+- Kill the network checks and inactive-outcome scan it was not waiting for.
+- Orphan unbounded network work.
 
 ## Shared wrapper and safety
 
 `bin/fm-sessionstart-run.sh` and `bin/fm-sessionstart-nudge.sh` share the same two eligibility owners.
-They source `bin/fm-gate-refuse-lib.sh` and stay silent for a no-mistakes gate agent identified by `NO_MISTAKES_GATE` or a `.no-mistakes/repos/*.git` git-common-dir.
-They share `bin/fm-primary-scope-lib.sh` with `bin/fm-turnend-guard.sh`, so every hook uses one primary-detection owner.

-The Ahoy skill owns the rule that this marked operational input is never a captain-authored session boundary, including its narrow legacy compatibility cases, and its own step 0 helm check is the fallback that protects a nudge-tier harness whose first command is a skill.

+### Nudge wrapper lock check
+
+Before printing, the nudge wrapper reads `state/.lock` and walks at most eight parents from its own pid.
+It does this in its own separate, hard-coded loop, independent of two other ownership checks:
+
+- The shared sixteen-hop ancestry walk in `bin/fm-session-lock-lib.sh` that `bin/fm-lock.sh` uses for anchor selection and ownership.
+- Pi's `lockOwnership()`.

 If the lock names a live pid in that ancestry, session start already ran in this harness session and the wrapper stays silent.
-Every ordinary transport path in both wrappers exits 0, including malformed state and adapter errors, because a Claude SessionStart exit 2 blocks session initialization.
-The run wrapper's internal `--pi-prerequisite` mode uses silent exit 3 only for an intentional gate or scope stand-down, letting Pi distinguish ineligibility from an eligible empty native result without changing any harness hook's exit contract.
-A lock another session holds and a truncated digest therefore surface as digest text, while broken GitHub auth surfaces through the deferred network result inline or as a wake; none becomes a refusal to open the session.

+### Exit codes
+

+The reason is that a Claude SessionStart exit 2 blocks session initialization.
+
+The run wrapper's internal `--pi-prerequisite` mode uses silent exit 3 only for an intentional gate or scope stand-down.
+That exit lets Pi distinguish ineligibility from an eligible empty native result.
+It does not change any harness hook's exit contract.
+
+These conditions therefore surface as follows:
+
+- A lock another session holds surfaces as digest text.
+- A truncated digest surfaces as digest text.
+- Broken GitHub auth surfaces through the deferred network result, inline or as a wake.
+
+None of these becomes a refusal to open the session.
 
 ## Harness transports
 
-| Harness | Tier | Tracked transport | Current compatibility |
-| --- | --- | --- | --- |
-| Claude | Run | `.claude/settings.json` registers one unmatched `SessionStart` hook, invoked through `CLAUDE_PROJECT_DIR` with a 180s timeout; the wrapper reads `source` from the hook payload. | Native stdout context injection is supported. |
-| Codex exec | Run | `.codex/hooks.json` anchors to the hook process working directory, verifies a Firstmate-shaped hook-bearing root, and pipes the hook payload into the wrapper with a 180s timeout. | Native stdout context injection is supported under `codex exec`. |
-| Codex interactive TUI | Uncovered | None. | Codex 0.146.0 does not fire the tracked project `SessionStart` hook in its interactive TUI; Firstmate ships no global hook, has no tracked compaction or re-emit channel, and does not claim instruction-refresh delivery for this surface. |
-| Pi / pi-signed | Run | `.pi/extensions/fm-primary-turnend-guard.ts` maps `session_start` reasons `startup`, `new`, `resume`, and `fork` onto wrapper sources, refines a Pi-reported `startup` to `resume` only when a continuation, resume-selection, or explicit-session flag accompanies a session header older than the current process, maps a fork flag to `fork`, and handles `session_compact` as the compaction equivalent; setup-created entries such as `--name` are not restoration evidence. | Each mapped session generation starts one native prerequisite, and `before_agent_start` awaits its matching result and returns one persistent context message before the first provider call; Pi's `reload` reason is deliberately unmapped, as it always was. |
-| OpenCode | Nudge | `.opencode/plugins/fm-primary-sessionstart-nudge.js` listens for `session.created`, runs once per session id, and calls `client.session.promptAsync` only when the wrapper prints a nudge. | Interactive TUI delivery is supported; headless `opencode run` is intentionally fail-open because the process can exit before the queued turn. That early exit is also why OpenCode cannot use the run tier. |
-| Grok | Nudge | `.grok/hooks/fm-primary-sessionstart-nudge.json` registers a project `SessionStart` hook and invokes the wrapper through inline-defaulted `${GROK_WORKSPACE_ROOT:-}`. | The project hook runs when the checkout is trusted, but Grok currently discards hook stdout from model context, so this path is intentionally fail-open and cannot use the run tier. |
-| Cursor | Run | `.cursor/hooks.json` registers `sessionStart`, anchored through `$CURSOR_PROJECT_DIR` with a 180s timeout, invoking `bin/fm-sessionstart-cursor.sh`. | Cursor's payload has no `source` field, so the registration supplies `--source` itself, and the adapter returns the digest as `additional_context`. Project hooks load only when the workspace is launched with `--trust`. |
-| omp | Run | `.omp/extensions/fm-primary-turnend-guard.ts`, auto-discovered from the home with no trust gate, starts the wrapper at `session_start` and has `before_agent_start` await it and return one persistent context message before the first provider call, exactly as Pi's does; `session_compact` is the compaction equivalent. | omp's `session_start` carries no reason field (verified 18.1.11), so the source is derived following the Cursor precedent: the first start of the process is `startup`, or `resume` when the launch line carried `--continue`/`-c` or `--resume`/`-r`; a later in-process start (`/new`, `/resume`, `/fork`) is `clear`, which re-emits only when this lock owner completed a full startup. `before_agent_start` message delivery was verified to reach model context on 18.1.11. |
-| Cursor compaction | Uncovered | None. | Cursor's `preCompact` response can return only `user_message` and is absent from Cursor's `additional_context` step set, so it cannot inject a re-emit digest. Delivering one needs its own design and is deliberately deferred to a follow-up; a Cursor primary does not re-emit its digest after a compaction. |
-
-Cursor's `sessionStart` fires at every session open with no source distinction, including a resumed session, so a resume re-runs the full digest; that is redundant and idempotent rather than a lost helm.
-Cursor's compaction surface is uncovered in the same sense as Codex's interactive TUI above: Firstmate registers nothing for `preCompact`, so a compacted Cursor session keeps whatever context survived rather than receiving a fresh digest.
-
-Pi is the only adapter that injects a message rather than hook stdout, so whatever it injects must carry operational provenance or the Ahoy skill would have to guess whether it was captain-authored.
-For `session_start`, the extension activates a session-id and monotonic-generation owner synchronously, starts the wrapper once, and makes `before_agent_start` await that same promise before returning Pi's persistent `message` result.
-Replacement or shutdown stops the matching process group, and stale generations cannot deliver into the active session.
-An eligible native failure or empty result settles before the extension returns the existing exact manual instruction, so native and manual startup never run concurrently.
-An intentional gate or non-primary stand-down returns no message, and context-preserving sources retain their existing silent result when the current process already holds the lock.
-Manual and automatic compaction retain the existing persistent delivery path because an automatic retry may have no new `before_agent_start`, but that path shares the same generation cancellation and exactly-once claim.
+Each subsection below gives one harness surface's tier, its tracked transport, and its current compatibility.
+
+### Claude
+
+Claude is a run-tier harness.
+`.claude/settings.json` registers one unmatched `SessionStart` hook, invoked through `CLAUDE_PROJECT_DIR` with a 180s timeout.
+The wrapper reads `source` from the hook payload.
+Native stdout context injection is supported.
+
+### Codex exec
+
+Codex exec is a run-tier harness.
+The `.codex/hooks.json` transport does three things:
+
+1. It anchors to the hook process working directory.
+2. It verifies a Firstmate-shaped hook-bearing root.
+3. It pipes the hook payload into the wrapper with a 180s timeout.
+
+Native stdout context injection is supported under `codex exec`.
+
+### Codex interactive TUI
+
+The Codex interactive TUI is uncovered and has no tracked transport.
+Codex 0.146.0 does not fire the tracked project `SessionStart` hook in its interactive TUI.
+Firstmate ships no global hook and has no tracked compaction or re-emit channel for it.
+Firstmate does not claim instruction-refresh delivery for this surface.
+
+### Pi and pi-signed
+
+Pi and pi-signed are run-tier harnesses.
+The tracked transport is `.pi/extensions/fm-primary-turnend-guard.ts`.
+The extension maps Pi events onto wrapper sources:
+
+- It maps `session_start` reasons `startup`, `new`, `resume`, and `fork` onto wrapper sources.
+- It refines a Pi-reported `startup` to `resume` only when a continuation, resume-selection, or explicit-session flag accompanies a session header older than the current process.
+- It maps a fork flag to `fork`.
+- It handles `session_compact` as the compaction equivalent.
+- Pi's `reload` reason is deliberately unmapped, as it always was.
+
+Setup-created entries such as `--name` are not restoration evidence.
+
+Each mapped session generation starts one native prerequisite.
+`before_agent_start` awaits its matching result and returns one persistent context message before the first provider call.
+
+#### Pi message delivery
+
+Pi is the only adapter that injects a message rather than hook stdout.
+So whatever it injects must carry operational provenance, or the Ahoy skill would have to guess whether it was captain-authored.
+
+For `session_start`, the extension does the following:
+
+1. It activates a session-id and monotonic-generation owner synchronously.
+2. It starts the wrapper once.
+3. It makes `before_agent_start` await that same promise before returning Pi's persistent `message` result.
+
+Replacement or shutdown stops the matching process group.
+Stale generations cannot deliver into the active session.
+
+An eligible native failure or empty result settles before the extension returns the existing exact manual instruction.
+So native and manual startup never run concurrently.
+
+An intentional gate or non-primary stand-down returns no message.
+Context-preserving sources retain their existing silent result when the current process already holds the lock.
+
+Manual and automatic compaction retain the existing persistent delivery path, because an automatic retry may have no new `before_agent_start`.
+That path still shares the same generation cancellation and exactly-once claim.
+
 The extension encodes an unencoded digest or fallback as `session-start` operational input and leaves an already-encoded nudge alone.
-It streams the hook to completion and retains at most 512 KiB for message delivery; this approved containment keeps the prefix and appends a loud `PI SESSION-START DELIVERY TRUNCATED` marker with direct-inspection guidance whenever the digest is incomplete.
+
+#### Pi delivery size limit
+
+The extension streams the hook to completion and retains at most 512 KiB for message delivery.
+Whenever the digest is incomplete, this approved containment keeps the prefix and appends a loud `PI SESSION-START DELIVERY TRUNCATED` marker with direct-inspection guidance.
+
+### OpenCode
+
+OpenCode is a nudge-tier harness.
+The `.opencode/plugins/fm-primary-sessionstart-nudge.js` plugin does three things:
+
+- It listens for `session.created`.
+- It runs once per session id.
+- It calls `client.session.promptAsync` only when the wrapper prints a nudge.
+
+Interactive TUI delivery is supported.
+Headless `opencode run` is intentionally fail-open, because the process can exit before the queued turn.
+That early exit is also why OpenCode cannot use the run tier.
 
 The OpenCode nudge runs only on `session.created`.
-The watcher-arm and turn-end plugins run later on `session.idle`, and the guard lets the watcher coordinator act first, so the plugins do not race for one lifecycle event.
+The watcher-arm and turn-end plugins run later, on `session.idle`.
+The guard lets the watcher coordinator act first, so the plugins do not race for one lifecycle event.
+
+### Grok
+
+Grok is a nudge-tier harness.
+`.grok/hooks/fm-primary-sessionstart-nudge.json` registers a project `SessionStart` hook and invokes the wrapper through inline-defaulted `${GROK_WORKSPACE_ROOT:-}`.
+The project hook runs when the checkout is trusted.
+Grok currently discards hook stdout from model context.
+So this path is intentionally fail-open and cannot use the run tier.
 
 Grok's guaranteed-loading alternative is a global token-guarded hook like the pattern used by `bin/fm-spawn.sh`.
-That alternative expands trust and writes outside this repository, so Firstmate never installs it or grants folder trust automatically.
+That alternative expands trust and writes outside this repository.
+So Firstmate never installs it or grants folder trust automatically.
+
+### Cursor
+
+Cursor is a run-tier harness for session open.
+`.cursor/hooks.json` registers `sessionStart`, anchored through `$CURSOR_PROJECT_DIR` with a 180s timeout, invoking `bin/fm-sessionstart-cursor.sh`.
+Cursor's payload has no `source` field, so the registration supplies `--source` itself.
+The adapter returns the digest as `additional_context`.
+Project hooks load only when the workspace is launched with `--trust`.
+
+Cursor's `sessionStart` fires at every session open with no source distinction, including a resumed session.
+So a resume re-runs the full digest.
+That is redundant and idempotent rather than a lost helm.
+
+### omp
+
+omp is a run-tier harness.
+The tracked transport is `.omp/extensions/fm-primary-turnend-guard.ts`, which is auto-discovered from the home with no trust gate.
+The extension starts the wrapper at `session_start`.
+It has `before_agent_start` await the wrapper and return one persistent context message before the first provider call, exactly as Pi's does.
+`session_compact` is the compaction equivalent.
+
+omp's `session_start` carries no reason field (verified 18.1.11).
+So the source is derived following the Cursor precedent:
+
+| omp session start | Source |
+| --- | --- |
+| The first start of the process | `startup` |
+| The first start of the process, when the launch line carried `--continue`/`-c` or `--resume`/`-r` | `resume` |
+| A later in-process start (`/new`, `/resume`, `/fork`) | `clear` |
+
+A later in-process `clear` re-emits only when this lock owner completed a full startup.
+`before_agent_start` message delivery was verified to reach model context on 18.1.11.
+
+### Cursor compaction
+
+Cursor compaction is uncovered and has no tracked transport.
+Cursor's `preCompact` response can return only `user_message` and is absent from Cursor's `additional_context` step set.
+So it cannot inject a re-emit digest.
+Delivering one needs its own design and is deliberately deferred to a follow-up.
+A Cursor primary does not re-emit its digest after a compaction.
+
+Cursor's compaction surface is uncovered in the same sense as [Codex's interactive TUI](#codex-interactive-tui).
+Firstmate registers nothing for `preCompact`.
+So a compacted Cursor session keeps whatever context survived rather than receiving a fresh digest.
 
 ## Regression coverage
 
-`tests/fm-sessionstart-nudge.test.sh` proves the nudge wrapper's silence for both gate signals, an unmarked linked worktree, a missing state directory, and an already-owned lock, plus its exact U+2063 `FIRSTMATE_OP:`-prefixed, `session-start`-typed one-line output.
+### Wrapper and Pi extension suite
+
+`tests/fm-sessionstart-nudge.test.sh` is a portable suite.
+It proves the nudge wrapper's silence for these cases:
+
+- Both gate signals.
+- An unmarked linked worktree.
+- A missing state directory.
+- An already-owned lock.
+
+It also proves the nudge wrapper's exact U+2063 `FIRSTMATE_OP:`-prefixed, `session-start`-typed one-line output.
+
 It separately proves the run wrapper's silence for the gate environment and an unmarked linked worktree, including the internal Pi prerequisite's explicit silent stand-down.
-It proves the run wrapper's source routing end to end against a real `fm-session-start.sh`, including completion-gated `--reemit` selection, resume delegation, Pi CLI continuation classification, an unrecognized source falling through to the full digest, and bounded loud delivery of an oversized Pi digest.
-The same portable suite proves provider exclusion until settlement, exactly-one execution and context delivery, interruption, process-tree retirement, two rapid replacements, stale completion, eligible empty output, spawn error, wrapper timeout output, truncation, ineligible stand-down, and compaction cancellation through the extension's public event surface.
-`tests/fm-session-start.test.sh` proves the runtime bound through the forced pure-Bash fallback: a TERM-resistant digest that exceeds its budget is force-killed with its grandchild, still emits its completed stages, names the incomplete stage and every stage it never reached, leaves no completion proof, and exits 0.

+
 `tests/fm-pi-primary-live-e2e.test.sh` and `tests/fm-opencode-primary-live-e2e.test.sh` exercise native startup paths with first-message and later-message Ahoy regressions.
-`tests/fm-cursor-primary.test.sh` proves the Cursor adapter over real processes: `sessionStart` emits the whole digest as `additional_context` with a caller-supplied `--source`, stays silent in a child worktree, lets the run wrapper stand down on the Cursor-delivered duplicate, and keeps `preCompact` unregistered so the deferred surface cannot be reintroduced unnoticed.

 `FM_CURSOR_PRIMARY_LIVE_E2E=1 tests/fm-cursor-primary-live-e2e.test.sh` proves the injected digest actually reaches model context in a real cursor-agent session.
-`tests/fm-sessionstart-hook-live-e2e.test.sh` is the opt-in live guard for the Claude, Codex exec, and Pi run-tier adapters; it confirms each installed adapter in that suite invokes the run wrapper and delivers its output into context.
-It verifies context-preserving reopen sources for those adapters and context-reset delivery wherever their tracked TUI surface is reachable.
-Its separate `FM_PI_SESSIONSTART_RACE_LIVE_E2E=1` mode uses real Pi with an offline deterministic provider and a barrier-controlled `/new` digest, proving both an immediate prompt and a completed-before-prompt control make their first provider call with exactly one native startup context and no manual execution.
-Cursor uses the separate primary live guard named above because its source-free `sessionStart` and stop-hook park are validated together.

 # Captain-hold lifecycle mechanism
 
+This document explains how a captain call is held, answered, reconciled, shown, and verified.
+It is for maintainers changing `bin/fm-captain-hold.sh` or any surface that reads or closes a captain hold.
+
 The normative policy is owned by `.agents/skills/captain-hold-lifecycle/SKILL.md` and is not restated here.
 This document records the deterministic mechanism, structured surfaces, compatibility contract, and privacy-safe regression evidence.

 ## Mechanism
 
-A decision is not a separate thing in this system: it is an ordinary backlog task held for the captain, and the task id is the identity every surface and channel uses.
+A decision is not a separate thing in this system.
+It is an ordinary backlog task held for the captain, and the task id is the identity every surface and channel uses.
 `bin/fm-captain-hold.sh` is the only lifecycle command layered on that primitive.
-The command addresses the active home's configured data directory, so the existing backlog remains the only durable work database and a secondmate-owned captain call stays in the secondmate home.
+The command addresses the active home's configured data directory.
+As a result, the existing backlog remains the only durable work database, and a secondmate-owned captain call stays in the secondmate home.
 It never reads report bodies, review artifacts, terminal output, or chat.
 
-The `hold` subcommand is the mandatory captain-hold creation path: it uses an existing task or creates one when nothing exists to hold, records its UTC hold-set timestamp as the leading line of the task body, then invokes the underlying tasks-axi hold operation and verifies both records.
+### Subcommands at a glance
+
+| Subcommand | What it does | Details |
+| --- | --- | --- |
+| `hold` | Creates or reuses a task and holds it for the captain. | [Creating a hold](#creating-a-hold-hold) |
+| `answer` | Records the captain's exact words and resolves the call. | [Answering a call](#answering-a-call-answer) |
+| `complete` | Records the reviewed captain-held task ids in the originating task's metadata. | [Recording a reviewed inventory](#recording-a-reviewed-inventory-complete) |
+| `verify` | Read-only check that scout teardown runs before removing source state. | [Checking before scout teardown](#checking-before-scout-teardown-verify) |
+| `open` | Read-only check of whether a row is still an open captain call. | [Cleanup never closes a captain call](#cleanup-never-closes-a-captain-call) |
+| `answers` | Channel-agnostic entry point for keyed answers. | [Answer-time resolution](#answer-time-resolution) |
+| `bind`, `unbind`, `binding` | Record that a captured-answer source feeds the keyed-answer intake. | [Source bindings](#source-bindings) |
+| `reconcile-requests` | Internal intake that records a reconcile request from a board selection. | [Reconcile](#reconcile-re-check-reality-never-a-blind-close) |
+| `reconcile close`, `reconcile note`, `reconcile list` | Retire or list pending reconcile requests. | [Verifying and retiring a request](#verifying-and-retiring-a-request) |
+| `diverged` | Read-only report of a call whose two records disagree. | [Record divergence](#record-divergence) |
+
+### Creating a hold (`hold`)
+
+The `hold` subcommand is the mandatory captain-hold creation path.
+It works in this order:
+
+1. It uses an existing task, or creates one when nothing exists to hold.
+2. It records the task's UTC hold-set timestamp as the leading line of the task body.
+3. It invokes the underlying tasks-axi hold operation.
+4. It verifies both records.
+
 Publishing the stamp first ensures a snapshot cannot observe a newly captain-held task without the timestamp that defines its age.
-Retries of an active hold preserve its hold-set timestamp, while re-holding released work starts a new timestamped lifecycle; a closed task is refused rather than reopened, and `--until` stores the captain's own deferral date through tasks-axi's date gate.
 
-The `answer` subcommand records the captain's exact words and resolves the call in the same act: it closes a question-shaped call, while `answer --release` frees a captain-gated work item to proceed without completing it.
-It requires a non-empty captain decision file of at most 8192 bytes, durably writes a resolution block carrying the decision digest and a `Resolution mode:` while retaining the leading hold-set stamp until the selected `tasks-axi done` or `tasks-axi unhold` transition succeeds, then restores the successful record's resolution-first body ordering (the previous body remains preserved below the block and archived through tasks-axi `--archive-body`).
+Repeat and edge cases:
+
+- Retries of an active hold preserve its hold-set timestamp.
+- Re-holding released work starts a new timestamped lifecycle.
+- A closed task is refused rather than reopened.
+- `--until` stores the captain's own deferral date through tasks-axi's date gate.
+
+### Answering a call (`answer`)
+
+The `answer` subcommand records the captain's exact words and resolves the call in the same act.
+
+| Form | Effect |
+| --- | --- |
+| `answer` | Closes a question-shaped call. |
+| `answer --release` | Frees a captain-gated work item to proceed without completing it. |
+
+It requires a non-empty captain decision file of at most 8192 bytes.
+It then works in this order:
+
+1. It durably writes a resolution block carrying the decision digest and a `Resolution mode:`.
+2. It retains the leading hold-set stamp until the selected `tasks-axi done` or `tasks-axi unhold` transition succeeds.
+3. It then restores the successful record's resolution-first body ordering.
+   The previous body remains preserved below the block and archived through tasks-axi `--archive-body`.
+
 If the close is interrupted, the still-held task therefore keeps its original age basis.
 A matching retry also completes any resolution-first normalization left unfinished after the close itself succeeded.
-An exact retry is idempotent only when the requested close mode matches the newest record; a drifted answer or mode mismatch is rejected, while a re-held task accepts a new answer as a new record on top.
-On a task closed outside the script, `answer` records the missing block only when the captain-hold annotations tasks-axi preserves through a close prove the captain owned it, and it verifies the task stays closed.
-A hold whose `--until` date has passed keeps those annotations while tasks-axi reports it no longer held, so an expired deferral remains answerable.
 
-The `complete` subcommand unions the reviewed captain-held task ids into `decision_keys=` and appends `decisions_reviewed=1` while originating task metadata is live.
+### Answer retries and tasks closed elsewhere
+
+- An exact retry is idempotent only when the requested close mode matches the newest record.
+- A drifted answer or a mode mismatch is rejected.
+- A re-held task accepts a new answer as a new record on top.
+
+On a task closed outside the script, `answer` records the missing block only when the captain-hold annotations tasks-axi preserves through a close prove the captain owned it.
+It also verifies the task stays closed.
+
+A hold whose `--until` date has passed keeps those annotations while tasks-axi reports it no longer held.
+An expired deferral therefore remains answerable.
+
+### Recording a reviewed inventory (`complete`)
+
+While originating task metadata is live, the `complete` subcommand unions the reviewed captain-held task ids, called the reviewed inventory, into `decision_keys=` and appends `decisions_reviewed=1`.
 A post-teardown visual review can complete against the surviving report and durable tasks without recreating volatile task metadata.
-It accepts `--none` as an explicit semantic inventory result, refused while the origin still has a lifecycle-open keyed status decision, and verifies every listed task against tasks-axi before recording completion.
-With a non-empty inventory it appends a `captain-held [key=<key>]` transfer event naming the reviewed inventory for every still-open keyed status decision, which `bin/fm-classify-lib.sh` recognizes as closing the live status copy without claiming that the captain has answered it.

+`complete` accepts `--none` as an explicit semantic inventory result.
+`--none` is refused while the origin still has a lifecycle-open keyed status decision.

+
+With a non-empty inventory, `complete` appends a `captain-held [key=<key>]` transfer event for every still-open keyed status decision.
+The event names the reviewed inventory.
+`bin/fm-classify-lib.sh` recognizes it as closing the live status copy without claiming that the captain has answered it.
+
+### Checking before scout teardown (`verify`)
 
 Scout teardown calls the read-only `verify` subcommand after checking for the report and before removing any source state.
-`verify` requires the recorded attestation, requires every recorded inventory entry to still be durable (actively captain-held, or carrying a recorded answer), and fails on any keyed status decision that opened after the last `complete`, which makes re-running `complete` the repair.
+`verify` checks three things:
+
+- The recorded attestation exists.
+- Every recorded inventory entry is still durable: actively captain-held, or carrying a recorded answer.
+- No keyed status decision opened after the last `complete`.
+
+A keyed status decision opened after the last `complete` makes `verify` fail, and re-running `complete` is the repair.
 The `--force` path remains the explicit captain-approved discard escape hatch.
 
 ## Cleanup never closes a captain call
 
-The policy prefers holding the very work item a question gates, so the backlog row a finished task's cleanup is about to close is routinely the captain's own call.
-`bin/fm-teardown.sh` therefore asks the read-only `open` subcommand before its automatic close: exit 0 means the row is still an open captain call (not Done, `hold_kind: captain`), 1 means it is not, and 2 means the answer could not be established, which teardown treats as a refusal before any destructive step rather than as permission to close.
-On 0 only the close changes: after cleanup and still under the task's own lock, teardown records one `Deliverable of the finished work: ...` line at the end of the task body, copies a supported pull request or canonical `data/<id>/report.md` into the row's structured artifact fields, and runs `tasks-axi reopen`, so the row returns to Queued with its hold intact and remains on the appropriate Captain's Call or Charted Next decision surface instead of reading as work still under way.
-The pending-close record teardown already stages before destructive cleanup carries that intent as a `mode=retain` line, so an interrupted cleanup replays the retention at the next session start through the same record, validator, and lock as an ordinary close and never closes the row; if the captain answers before replay, `answer` validates that record and copies any supported retained pull request or report into the row before closing it, after which replay retires the record.
-Two retained-delivery gaps remain bounded by tasks-axi 0.2.6 and are recorded for separate upstream work rather than representing defects introduced by this branch.
-A retained local-only delivery cannot reach the row because `--note` exists on `tasks-axi done` but not on `tasks-axi update`, while the durable pending-close record carrying that note is retired when retention completes.
-A relocated retained report cannot reach the row because tasks-axi accepts only `data/<id>/report.md`: `done` reports `Task report link must be a data/<id>/report.md path`, and `update` reports `--report must be a data/<id>/report.md path`.
-When an interrupted retention leaves such a relocated report in the validated pending-close record, `answer` skips only that known-unsupported row artifact and closes normally, so the delivery remains absent from Recently Landed instead of wedging the captain's answer.
-A pending-close record that fails validation outright is a different case and still refuses the answer, but the refusal names the record and the validation reason so the captain can repair it rather than facing a bare failure.
-`--force` does not lift the deferral, because it authorizes discarding unlanded work, never the captain's question; only `answer` with the captain's words or evidence-backed `reconcile close` resolves the call, by either closing the question or releasing the gated work.
+The policy prefers holding the very work item a question gates.
+So the backlog row a finished task's cleanup is about to close is routinely the captain's own call.
+
+`bin/fm-teardown.sh` therefore asks the read-only `open` subcommand before its automatic close:
+
+| `open` exit | Meaning | What teardown does |
+| --- | --- | --- |
+| 0 | The row is still an open captain call (not Done, `hold_kind: captain`). | Retains the row, as described below. |
+| 1 | The row is not an open captain call. | Proceeds with its automatic close. |
+| 2 | The answer could not be established. | Treats it as a refusal before any destructive step, never as permission to close. |
+
+### Retaining the row on exit 0
+
+On 0 only the close changes.
+After cleanup, and still under the task's own lock, teardown does three things:
+
+- It records one `Deliverable of the finished work: ...` line at the end of the task body.
+- It copies a supported pull request or canonical `data/<id>/report.md` into the row's structured artifact fields.
+- It runs `tasks-axi reopen`.
+
+The row returns to Queued with its hold intact.
+It remains on the appropriate Captain's Call or Charted Next decision surface instead of reading as work still under way.
+
+### Interrupted cleanup
+
+Teardown already stages a pending-close record before destructive cleanup.
+That record carries the retention intent as a `mode=retain` line.
+An interrupted cleanup therefore replays the retention at the next session start through the same record, validator, and lock as an ordinary close, and never closes the row.
+
+If the captain answers before replay, `answer` validates that record and copies any supported retained pull request or report into the row before closing it.
+Replay then retires the record.
+
+### Known retained-delivery gaps
+
+Two retained-delivery gaps remain bounded by tasks-axi 0.2.6.
+They are recorded for separate upstream work rather than representing defects introduced by this branch.
+
+- A retained local-only delivery cannot reach the row.
+  `--note` exists on `tasks-axi done` but not on `tasks-axi update`, while the durable pending-close record carrying that note is retired when retention completes.
+- A relocated retained report cannot reach the row, because tasks-axi accepts only `data/<id>/report.md`.
+  `done` reports `Task report link must be a data/<id>/report.md path`, and `update` reports `--report must be a data/<id>/report.md path`.
+
+When an interrupted retention leaves such a relocated report in the validated pending-close record, `answer` skips only that known-unsupported row artifact and closes normally.
+The delivery then remains absent from Recently Landed instead of wedging the captain's answer.
+
+A pending-close record that fails validation outright is a different case, and it still refuses the answer.
+The refusal names the record and the validation reason, so the captain can repair it rather than facing a bare failure.
+
+### What `--force` does not lift
+
+`--force` does not lift the deferral, because it authorizes discarding unlanded work, never the captain's question.
+Only `answer` with the captain's words or evidence-backed `reconcile close` resolves the call, by either closing the question or releasing the gated work.
 `bin/fm-backlog-transition-lib.sh` owns the transition and its record, and `bin/fm-captain-hold.sh --help` owns the predicate's contract.
 
 ## Answer-time resolution
 
 "A keyed answer resolves its matching captain-held task" is one capability with one owner.
-`answers` is its channel-agnostic entry point: it reads `<task-id>\t<answer>\t<label>[\t<mode>]` lines and resolves each named task through the same `answer` path, so every guard applies identically no matter which channel the answer arrived on.
-The optional mode column carries a card-declared close: `done` (default) completes the task and `release` lifts the hold so held work resumes; any other value is skipped.
-A key that names no task, names a task that is not captain-held, or names a task already closed is reported as `skipped:` and feeds nothing; a replay whose answer and requested close mode match the newest record is an idempotent `closed:`, while a mode mismatch is skipped; and the command exits nonzero when any key was skipped.

+
+The optional mode column carries a card-declared close:
+
+| Mode | Effect |

+| A replay whose answer and requested close mode match the newest record | An idempotent `closed:`. |
+| A replay with a mode mismatch | Skipped. |
+

 `--source` is provenance text recorded in the durable decision, never a behavior switch, and the command carries no per-channel branch.
 
-`bind`, `unbind`, and `binding` record that a captured-answer source feeds this intake, as a private record under `state/decision-bindings/`; an unbound source feeds nothing, so the path is opt-in per source, and `bind` deliberately does not require the source to exist yet.

+
+### Channels that feed the intake
 
 Two channels feed that one intake today, and both are ordinary callers rather than special cases.
-`bin/fm-send.sh --resolve-key` is the chat channel: its status-log close for a key the status log still owns is owned by that script's header, and a key the status log no longer owns is resolved to a still-open captain-held task - the key as a task id, then the legacy derived identity - and fed as one keyed line.
-`bin/fm-procevent.sh` is the captured-result channel: after capture, a bound built-in source has its result passed to `bin/fm-procevent-<adapter>.sh answers <result-file>` and whatever that prints is piped into the intake, so any built-in adapter with an `answers` command works and the runner names no adapter, parses no result, and carries no decision rule.
+
+`bin/fm-send.sh --resolve-key` is the chat channel:
+
+- For a key the status log still owns, that script's header owns the status-log close.
+- A key the status log no longer owns is resolved to a still-open captain-held task and fed as one keyed line.
+  The script tries the key as a task id first, then the legacy derived identity.
+
+`bin/fm-procevent.sh` is the captured-result channel:
+
+- After capture, the runner passes a bound built-in source's result to `bin/fm-procevent-<adapter>.sh answers <result-file>`.
+- The runner pipes whatever that prints into the intake.
+- Any built-in adapter with an `answers` command therefore works.
+- The runner names no adapter, parses no result, and carries no decision rule.
+
+`bin/fm-procevent-lavish.sh answers` is one such built-in adapter command.
+It reads only rows tagged `choice` and relays a card's declared close mode.
+It can never let freeform captain prose forge a task id or a mode.
+
 Trusted external process-event adapters intentionally expose no answer operation and cannot feed this authority-bearing intake; [`extension-bindings.md`](extension-bindings.md#trust-boundary) owns that boundary.
-`bin/fm-procevent-lavish.sh answers` is one such adapter command; it reads only rows tagged `choice`, relays a card's declared close mode, and can never let freeform captain prose forge a task id or a mode.
 
 ## Reconcile: re-check reality, never a blind close
 
-A captain call can stop being a question without the captain ever answering it because the subject lands, the premise turns out to be false, or the choice becomes a matter of fact rather than the captain's to make.
+A captain call can stop being a question without the captain ever answering it.
+That happens when the subject lands, the premise turns out to be false, or the choice becomes a matter of fact rather than the captain's to make.
 `reconcile` is the standing third option for that case, and its whole point is that it is NOT an answer.
-It means "go verify the latest state", and it resolves in exactly one of two ways once that verification has actually been done: close the call with the evidence that made it moot, or leave it open with a note recording that it is genuinely still active.

+### The keyed-answer intake refuses reconcile
 
 The value remains reserved at the shared keyed-answer intake, which visibly refuses it from every channel and never passes it to `answer`.
 A reconcile value delivered through chat or any ordinary keyed-answer caller therefore cannot complete a task, lift a hold, write a resolution record, or create a reconcile request.
 
+### How a board selection creates a request
+
 Board request creation uses a separate captured-source seam.
-The board emits `fm-bearings-answer.v1` context with the slug-shaped selected option and freeform note in separate fields, so annotating Reconcile cannot turn it into an ordinary answer value.
-`bin/fm-procevent-lavish.sh answers` emits an exact non-reconcile selection, or a bare note when no option was selected, while `reconciles` emits only task ids whose structured selection is Reconcile and carries their notes as request provenance.
-Current rows require the versioned shape and the `choice` tag; a time-limited rollout branch accepts ordinary answers from the old question/answer shape but refuses its bare and separator-annotated reconcile values from both intakes because those rows do not separate the selected option from its note.

+That branch refuses the old shape's bare and separator-annotated reconcile values from both intakes, because those rows do not separate the selected option from its note.
 Every other structurally uncertain capture feeds neither intake, remains announced, and cannot forge a task id from freeform prose.
-The adapter-agnostic runner pipes reconcile rows into `reconcile-requests` only for a bound source, and that intake verifies the named binding again before it creates anything.

+Verification retires a request through one of two outcomes.
+Each outcome requires both the pending board-created request and the operator input that supports its claim:
 
 - `reconcile close <task-id> --evidence-file <path>` is the moot outcome.
   It writes a resolution record whose mode is `reconciled` and whose body is the supplied EVIDENCE under a `Reconciliation evidence:` label, then closes the task.
   The distinct mode and label are what keep the record honest: it says the call dissolved against verified evidence, and it never claims the captain answered.
 - `reconcile note <task-id> --note-file <path>` is the still-active outcome.
   It appends one dated `Captain hold reconciled:` note to the task body, leaves the hold in place, and retires the request.
-  The call stays the captain's, now carrying what the re-check found; a marker bound to the request timestamp, provenance, and note digest lets a matching retry finish retirement without appending again while a later request with the same finding still receives its own dated note.

+Dropped cards are named on stderr as `dropped-landed-card:` lines, so a rebuild states what it removed rather than quietly shrinking Captain's Call.
 The landing procedure requires one immediate board rebuild to remove already-stale merged-PR and superseded-version cards without a committed migration or change-worktree state mutation.
 A subject whose state cannot be established is kept, because a wrongly shown card is safer than a wrongly hidden call.
-The validator's reservation scope must equal the adapter's reconcile-classification scope, which is all card types because the captured payload carries no card type.

-Until then, an absent main-home task passes through this hygiene check unchanged, and its Reconcile selection remains announced but cannot create a main-home request because the main intake refuses an absent task.

 ## Structured read surfaces
 
+### Fleet snapshot buckets
+
 `bin/fm-fleet-snapshot.sh` parses canonical tasks-axi `(hold: ...)`, `(hold-kind: ...)`, and `(hold-until: ...)` metadata alongside existing backlog fields.
 It resolves every repeated `blocked-by:` edge against structured Done records and keeps missing blockers unresolved.
-It then assigns every captain hold exactly one `hold_bucket`, decided only from structured fields - `hold_kind`, `state`, `hold_until`, `unresolved_blocker_ids`, and the machine-written hold-set timestamp.
+It then assigns every captain hold exactly one `hold_bucket`.
+The bucket is decided only from structured fields: `hold_kind`, `state`, `hold_until`, `unresolved_blocker_ids`, and the machine-written hold-set timestamp.
 Hold reason and body prose are never matched, so no wording can hide, reveal, or reclassify a decision.
-The buckets are total and mutually exclusive: `blocked` when any blocker is unresolved, else `dated` while `hold_until` is in the future, else `aged` when an undated hold's hold-set timestamp is at least `FM_SNAPSHOT_UNDATED_HOLD_AGE_DAYS` old (default 14, floored elapsed days), else `live`.
+
+The buckets are total and mutually exclusive.
+The first matching row in this order decides the bucket:
+
+| Order | `hold_bucket` | Condition |
+| --- | --- | --- |
+| 1 | `blocked` | Any blocker is unresolved. |
+| 2 | `dated` | `hold_until` is in the future. |
+| 3 | `aged` | An undated hold's hold-set timestamp is at least `FM_SNAPSHOT_UNDATED_HOLD_AGE_DAYS` old (default 14, floored elapsed days). |
+| 4 | `live` | None of the above. |
+
 No captain hold can fall through them and none can match two, which is what keeps a hold from vanishing from every view.
 `captain_actionable` - waiting on the captain now - is exactly `hold_bucket == "live"`.
+
 Existing undated holds without a hold-set stamp fall back to the task's `since` date.
 That aging is a projection safety net only.
 The durable deferral remains re-holding with `--until`.
-Its secondmate-home summary classifies an actionable captain hold as `captain_decision` and preserves every captain hold in the bounded queued inventory of the owning home.

+
+### Bearings placement
 
 `bin/fm-bearings-snapshot.sh` places each captain hold by its `hold_bucket` and inspects no prose of its own.
-A `live` hold is a default Captain's Call entry.
-A `blocked`, `dated`, or `aged` hold leaves the default Captain's Call, renders as a Charted Next gate stating why - the blocking work, the `until <date>`, or the floored age - and contributes to the concrete `omitted[]` disclosure.
-`--all-decisions` reveals every captain hold available within the remote-summary bound and drops its gate, so an available hold is never in both Captain's Call and Charted Next.
+
+| `hold_bucket` | Where the hold appears |
+| --- | --- |
+| `live` | A default Captain's Call entry. |
+| `blocked`, `dated`, or `aged` | Leaves the default Captain's Call, renders as a Charted Next gate stating why - the blocking work, the `until <date>`, or the floored age - and contributes to the concrete `omitted[]` disclosure. |
+
+`--all-decisions` reveals every captain hold available within the remote-summary bound and drops its gate.
+An available hold is therefore never in both Captain's Call and Charted Next.
 An actively worked held task may also appear in Underway, which reports running work independently of those decision buckets.
 
+### Accepted limits
+
 Three accepted limits remain deliberate:
 
 - A remote or secondmate hold retains the producer home's age and aging decision from the summary's capture time and threshold rather than being recomputed by the parent.
 - A rare concurrent answer-close and re-hold race can leave the newly re-held task without its age basis.
-- Cross-home summaries remain bounded by `FM_SNAPSHOT_SECONDMATE_DECISIONS` and `FM_SNAPSHOT_SECONDMATE_QUEUED`; a remote deferred hold beyond those bounds is not exported, so it can be neither gated nor revealed.

+### Recently Landed notes
+
 [`bin/fm-landed-lib.sh`](../bin/fm-landed-lib.sh) owns Recently Landed's shared selection and artifact-display compatibility rules.
-A local-only landing's note is written by `tasks-axi done --note` as the last of the row's indented body lines rather than into the row title, so the snapshot reads that final line as the note as well as parsing the title, and the landing is published carrying its recorded note.

+The snapshot therefore reads that final line as the note as well as parsing the title, and the landing is published carrying its recorded note.
 A body that carries a captain resolution record is the captain's own prose and is never mined for that note, so a decision worded `local main` does not become a delivery artifact.
 The projection remains read-only and uses the canonical snapshot's structured fields, including the machine-written hold-set timestamp.
 
+### Merge-to-cleanup window
+
 The window between a merge landing and cleanup is an accepted structural residual rather than an oversight.
 That local window is normally only seconds wide and requires re-holding a task whose merge has just landed.
 A re-hold inside the window makes cleanup retain the row rather than publish it, so the delivery is omitted until the stale hold is cleared from that row.

 ## Record divergence
 
 A captain call can have two records, and closing one does not close the other.
-A `resolved [key=...]` line closes the status-log fold; the structured captain-held task closes only through `answer`.
-Until this guard existed, closing on the status side alone left no trace of the disagreement: the fold went quiet, the durable record kept saying the captain owed an answer, and nothing warned.

-It closes nothing, ever - a captain call closed wrongly leaves review entirely, so both reconciliation directions stay human-owned and the printed hint names both.

 Cost stays flat: one `tasks-axi list`, one key scan per status log, and the precise per-key fold only for a key that already names a still-open task.
-The comparison is refused unless the status directory is the active home's own, since tasks-axi reads that home's backlog and a mismatch would report one home's logs against another's tasks.

 ## Compatibility with pre-collapse installs
 
+The collapse is the change that made a decision an ordinary captain-held task whose key is its task id.
 Older installs created derived `<origin>-decision-<key>` identities through the retired `bin/fm-decision-hold.sh`.
 Those rows are already plain task ids, so they render, answer, verify, and close through the collapsed surfaces with no data migration.
-Three legacy inputs are resolved in place: a `decision_keys=` metadata entry that names no task resolves through `<origin>-decision-<entry>`; a channel key that names no task resolves the same way when the source's binding carries a concrete legacy origin; and resolution records written by the old script are recognized wherever a record is read.
-On the Beads backend, an attested legacy markdown id that resolves to no task is accepted through the row the markdown-to-beads hold migration produced, found by the authoritative evidence first: a row whose notes carry the marker line `migrated from data/backlog.md id <legacy id>`, either alone or followed by ` on <date>` as fm-hold-migration wrote it on 2026-09-04.
-Only when no row carries that marker line is the legacy id tried under the configured beads prefix, and that name-only guess is accepted solely for a single row still held for the captain - two such rows refuse rather than attest.

+
+Only when no row carries that marker line is the legacy id tried under the configured beads prefix.
+That name-only guess is accepted solely for a single row still held for the captain.
+Two such rows refuse rather than attest.
 Because that acceptance rests on a name rather than on evidence, `complete` names the resolved row beside each prefix-attested legacy id in its completion line, so the guess is auditable after the fact.
+
 A markdown home keeps its legacy rows verbatim, so its resolution is unchanged.

-It proves: cleanup of a finished task whose own row is the captain call leaves that call open, queued, held, carrying its deliverable, and visible in Bearings' Captain's Call, leaves no pending record behind, survives a `--force` cleanup, and closes only when `answer` records the captain's words, while an ordinary finished task in the same home still closes with its report link; an interrupted cleanup leaves the row In flight and untouched with its pending record, the next session start retains it as queued and held with the deliverable recorded when it remains unanswered, and an answer before replay preserves that record's completed report while closing the call so the next session start retires the satisfied record without losing the delivery from Recently Landed; a pending-close record that cannot be validated refuses the answer while naming the record and the reason; a relocated data directory keeps the retention in its one configured backlog; direct PR and local-only merge entrypoint calls refuse a still-held task before reaching the forge or moving local main, while a released pull request passes the guarded PR entrypoint, cleanup records its artifact, and Recently Landed publishes it; an ordinary release still survives zero-retention cleanup and archives when configured; a ship row whose captain hold cannot be read refuses cleanup before any destructive step and surfaces the read failure; the reconstructed silent-divergence case is signalled - a status resolution over a still-open captain-held task reaches both `diverged` and the drain's `RECORD DIVERGENCE` section, under the collapsed and the legacy identity alike, while the backlog task, its hold, and the status log all survive the report unchanged and the printed hint names both reconciliation directions; the false-signal boundary holds - a captain call with no routed work item, a verified `captain-held` transfer, a still-open status decision, an already answered call, and an ordinary task whose keyed question was answered all stay silent; a released call whose decision text is `local main`, closed with no artifact, is not published as a local-only landing; a report-only unresolved captain call refuses `--none` completion before teardown can erase the source; non-forced scout teardown always requires the durable inventory verification; the recorded-answer guard (a bare `tasks-axi done` close fails `verify` until `answer` records the captain's word, and an ordinary finished task cannot be dressed up as an answered call); answer-time resolution through a bound channel with task-id keys, including the `release` mode, mode-matched replay idempotence, and the refusal of drifted, mode-mismatched, absent, unheld, and already-closed keys; the chat channel reaching the same intake; hold-set stamping that precedes visible hold state, preserves an active lifecycle's timestamp, and resets after release; interrupted answer closure retaining the stamp until close and restoring resolution-first ordering on retry; deferral through `--until` leaving `captain_actionable` false until due; and every legacy path (composed identities through the shim, pre-collapse `decision_keys=` metadata, routed-resolution replay, and a concrete-origin binding).
+It proves the behaviors below.
 The suite does not test the accepted merge-to-cleanup re-hold window or asynchronous queued-forge landing because those events occur after the locally serialized merge command has returned.
 
-Two of its cases pin how a task body is read back rather than any decision behavior, because both paths that read one are otherwise silent when they get it wrong.
-Holding a task that carries a body, and cleanup's retention of a captain-held row, both work where the installed JSON::PP defaults `allow_nonref` off and therefore rejects the JSON-encoded bare string a shown scalar field arrives as; the case forces that older default back off and probes that the simulation really does reject a bare scalar, so it cannot pass vacuously on a lenient library.
+### Cleanup of a captain-held row
+
+- Cleanup of a finished task whose own row is the captain call leaves that call open, queued, held, carrying its deliverable, and visible in Bearings' Captain's Call.
+  That cleanup leaves no pending record behind.
+  The call survives a `--force` cleanup and closes only when `answer` records the captain's words.
+  An ordinary finished task in the same home still closes with its report link.
+- An interrupted cleanup leaves the row In flight and untouched with its pending record.
+  When the row remains unanswered, the next session start retains it as queued and held with the deliverable recorded.
+  An answer before replay preserves that record's completed report while closing the call, so the next session start retires the satisfied record without losing the delivery from Recently Landed.
+- A pending-close record that cannot be validated refuses the answer while naming the record and the reason.
+- A relocated data directory keeps the retention in its one configured backlog.
+
+### Merges, releases, and unreadable holds
+
+- Direct PR and local-only merge entrypoint calls refuse a still-held task before reaching the forge or moving local main.
+- A released pull request passes the guarded PR entrypoint, cleanup records its artifact, and Recently Landed publishes it.
+- An ordinary release still survives zero-retention cleanup and archives when configured.
+- A ship row whose captain hold cannot be read refuses cleanup before any destructive step and surfaces the read failure.
+- A released call whose decision text is `local main`, closed with no artifact, is not published as a local-only landing.
+
+### Divergence coverage
+
+- The reconstructed silent-divergence case is signalled.
+  A status resolution over a still-open captain-held task reaches both `diverged` and the drain's `RECORD DIVERGENCE` section, under the collapsed and the legacy identity alike.
+  The backlog task, its hold, and the status log all survive the report unchanged, and the printed hint names both reconciliation directions.
+- The false-signal boundary holds.
+  A captain call with no routed work item, a verified `captain-held` transfer, a still-open status decision, an already answered call, and an ordinary task whose keyed question was answered all stay silent.
+
+### Completion and verification
+
+- A report-only unresolved captain call refuses `--none` completion before teardown can erase the source.
+- Non-forced scout teardown always requires the durable inventory verification.
+- The recorded-answer guard holds: a bare `tasks-axi done` close fails `verify` until `answer` records the captain's word, and an ordinary finished task cannot be dressed up as an answered call.
+
+### Answers, stamps, and deferral
+
+- Answer-time resolution works through a bound channel with task-id keys.
+  This includes the `release` mode, mode-matched replay idempotence, and the refusal of drifted, mode-mismatched, absent, unheld, and already-closed keys.
+- The chat channel reaches the same intake.
+- Hold-set stamping precedes visible hold state, preserves an active lifecycle's timestamp, and resets after release.
+- Interrupted answer closure retains the stamp until close and restores resolution-first ordering on retry.
+- Deferral through `--until` leaves `captain_actionable` false until due.
+
+### Legacy paths
+
+- Every legacy path works: composed identities through the shim, pre-collapse `decision_keys=` metadata, routed-resolution replay, and a concrete-origin binding.
+
+### Task-body read-back cases
+
+Two of the suite's cases pin how a task body is read back rather than any decision behavior, because both paths that read one are otherwise silent when they get it wrong.
+
+The first case covers holding a task that carries a body, and cleanup's retention of a captain-held row.
+Both work where the installed JSON::PP defaults `allow_nonref` off and therefore rejects the JSON-encoded bare string a shown scalar field arrives as.
+The case forces that older default back off and probes that the simulation really does reject a bare scalar, so it cannot pass vacuously on a lenient library.
 A fleet host does carry such a library, and both failures reproduce on it natively with no shim, so that behavior is observed and not only simulated.
 The case still forces the older default rather than depending on the installed one, which is what makes it deterministic on any host.
-A retained body's non-ASCII characters also survive cleanup's rewrite as their exact UTF-8 bytes, and the case asserts bytes rather than decoded strings: a codepoint at or below U+00FF is the one a stream with no raw layer emits as a single latin-1 byte, and comparing decoded strings cannot see that.
+
+The second case covers a retained body's non-ASCII characters, which survive cleanup's rewrite as their exact UTF-8 bytes.
+The case asserts bytes rather than decoded strings.
+A codepoint at or below U+00FF is the one a stream with no raw layer emits as a single latin-1 byte, and comparing decoded strings cannot see that.
 It uses one row per character class, because any character above U+00FF makes the whole string print as UTF-8 and would mask the latin-1 case in a mixed body.
 That latin-1 byte loss also reproduces natively on the fleet host carrying the older library, with no shim.
 
-The markdown-to-beads migration family runs the same suite's beads fixture (bd-driven scratch graph, self-skipping on markdown-only tasks-axi installs) and proves: `verify` and `complete` resolve an attested legacy id through a migrated row's marker note, through the configured prefix when no row carries a note - naming the resolved row in the completion line - and through the marker note of a pre-collapse derived identity; a marker-noted row wins over an unrelated captain-held row occupying the bare prefix namesake; an unresolvable id is refused once naming the id (never an empty name); and the attested id stays in `decision_keys=` for idempotent re-verification.
-One case in that family needs no beads install and always runs: a stubbed tasks-axi that fails any markdown file override proves the captain-hold hold, answer, and close mutations reach a beads-configured home without one.
+### Markdown-to-beads migration family
+
+The markdown-to-beads migration family runs the same suite's beads fixture (bd-driven scratch graph, self-skipping on markdown-only tasks-axi installs).
+It proves:
+
+- `verify` and `complete` resolve an attested legacy id through a migrated row's marker note.
+- They resolve it through the configured prefix when no row carries a note, naming the resolved row in the completion line.
+- They resolve it through the marker note of a pre-collapse derived identity.
+- A marker-noted row wins over an unrelated captain-held row occupying the bare prefix namesake.

+

+It uses a stubbed tasks-axi that fails any markdown file override, and proves the captain-hold hold, answer, and close mutations reach a beads-configured home without one.
+
+### Reconcile coverage
+
+The reconcile path is pinned in the same suite:
 
-The reconcile path is pinned in the same suite: a reconcile answer arriving through the keyed-answer intake, in the default close mode and in the `release` mode a captain-gated work card declares, is refused and leaves both tasks held with no resolution record or request; only the separately bound captured-source intake records one durable request per task idempotently across a replay.
-It also proves the two verification outcomes - an evidence-backed `reconciled` close that records the evidence under its own label and never as the captain's words, and a note that leaves the call queued, held, and dated - while both outcomes refuse without a pending board request, each durable mutation applies only once across close, probe, and request-retirement failures, a later distinct request with the same note still appends its own dated record, every failed retirement is surfaced with its pending request retained, incompatible resolution modes cannot replay as captain answers, and normal close, release, and replay paths retire pending requests.
-The captured-source coverage proves Lavish deduplicates each card before separating versioned structured selections from notes, bare and annotated Reconcile choices never reach keyed answers, genuine current and legacy choices still close normally, legacy bare and separator-annotated reconcile values feed neither intake, mixed repeated selections preserve every other card's final value, the generic runner creates a request only through a verified bound source, chat reconcile text creates none, and the resulting board request authorizes evidence-backed closure.
-The board's half is pinned in `tests/fm-bearings-board.test.sh`: every published decision card carries exactly one reconcile option, authored options reserve that value across every card type, recommendations name authored options, a decision card whose structured subject appears in the payload's landed rows is dropped while a genuinely open one is kept even when an unrelated landed id contains its key after a newline, a build requires a fresh authoritative listed-open result before binding or arming, a reopen retires the pre-reopen source generation and waits for a fresh live listener, and a rebuild of an already-armed board with no live listener starts one.
-That suite drives its Lavish session through a protocol-shaped stub, and `tests/fm-bearings-board-lavish-live-e2e.test.sh` is the default-on capability guard for the installed provider; [`verification/process-event-sources.md`](verification/process-event-sources.md) owns the version-scoped evidence.
+- A reconcile answer arriving through the keyed-answer intake is refused, in the default close mode and in the `release` mode a captain-gated work card declares.
+  It leaves both tasks held with no resolution record or request.
+- Only the separately bound captured-source intake records one durable request per task, idempotently across a replay.
+
+It also proves the two verification outcomes:
+
+- An evidence-backed `reconciled` close records the evidence under its own label and never as the captain's words.
+- A note leaves the call queued, held, and dated.
+
+Around those outcomes, it proves:
+
+- Both outcomes refuse without a pending board request.
+- Each durable mutation applies only once across close, probe, and request-retirement failures.
+- A later distinct request with the same note still appends its own dated record.
+- Every failed retirement is surfaced with its pending request retained.
+- Incompatible resolution modes cannot replay as captain answers.
+- Normal close, release, and replay paths retire pending requests.
+
+The captured-source coverage proves:
+
+- Lavish deduplicates each card before separating versioned structured selections from notes.
+- Bare and annotated Reconcile choices never reach keyed answers.
+- Genuine current and legacy choices still close normally.
+- Legacy bare and separator-annotated reconcile values feed neither intake.
+- Mixed repeated selections preserve every other card's final value.
+- The generic runner creates a request only through a verified bound source.
+- Chat reconcile text creates none.
+- The resulting board request authorizes evidence-backed closure.
+
+### Board suite
+
+The board's half is pinned in `tests/fm-bearings-board.test.sh`:
+
+- Every published decision card carries exactly one reconcile option.
+- Authored options reserve that value across every card type.
+- Recommendations name authored options.
+- A decision card whose structured subject appears in the payload's landed rows is dropped.
+  A genuinely open one is kept even when an unrelated landed id contains its key after a newline.
+- A build requires a fresh authoritative listed-open result before binding or arming.
+- A reopen retires the pre-reopen source generation and waits for a fresh live listener.
+- A rebuild of an already-armed board with no live listener starts one.
+
+That suite drives its Lavish session through a protocol-shaped stub.
+`tests/fm-bearings-board-lavish-live-e2e.test.sh` is the default-on capability guard for the installed provider, and [`verification/process-event-sources.md`](verification/process-event-sources.md) owns the version-scoped evidence.
 [`verification/process-event-sources.md`](verification/process-event-sources.md) owns the process-event ownership and reclamation evidence exercised by `tests/fm-procevent.test.sh`.
 
-`tests/fm-classify-decision-key.test.sh` pins `status_key_closing_verb` itself: it separates a resolution from the durable-transfer close and from a still-open key, reports the last real transition across re-openings and both key positions, and treats a prose mention as no transition.

 # Remote second mates
 
+This page covers how to set up, provision, run, and retire a second mate whose Firstmate home lives on another host.
+It is for operators who run a remote second mate and for anyone checking its transport and safety behavior.
+
 Remote second mates place a whole persistent Firstmate home on another SSH-reachable host.
 The primary still owns routing and supervision, while the remote home owns its own projects, backlog, and workers.
 Firstmate does not support placing an individual worker remotely or failing a remote route over to a local replacement.
 
-The remote second-mate agent itself always runs on the [Herdr backend](herdr-backend.md) in the shared `fm-remote` session, and every path that provisions or launches one refuses a host that is not ready for it.
-`fm-remote` is reserved for remote fleet work and must not be used for personal work.
-The user's interactive Herdr session remains `default` and is not a remote-secondmate prerequisite.
-Herdr's remote-session server belongs to the host's own GUI login session rather than to the SSH connection, so the agent's endpoint survives every disconnection the primary's supervision depends on.
-Local second mates are unaffected and keep their ordinary backend and session selection, as do the workers a remote second mate supervises inside its own home.

+## Where the remote agent runs
+
+The remote second-mate agent itself always runs on the [Herdr backend](herdr-backend.md) in the shared `fm-remote` session.
+Every path that provisions or launches one refuses a host that is not ready for it.
+
+- `fm-remote` is reserved for remote fleet work and must not be used for personal work.
+- The user's interactive Herdr session remains `default` and is not a remote-secondmate prerequisite.
+- Herdr's remote-session server belongs to the host's own GUI login session rather than to the SSH connection.
+  As a result, the agent's endpoint survives every disconnection the primary's supervision depends on.
+- Local second mates are unaffected and keep their ordinary backend and session selection.
+  So do the workers a remote second mate supervises inside its own home.
 
 ## Prerequisites
 
-Configure an SSH alias in the primary account's normal OpenSSH configuration.
-Use ordinary public-key authentication, strict host-key verification, and a dedicated remote account where practical.
-Do not enable agent forwarding for Firstmate.
-`fm-on.sh` also disables agent forwarding, forwarding setup, and configured `SendEnv` patterns on every call, and arms bounded SSH dead-peer detection so a vanished host (a reboot, a dropped link) fails within a bounded window instead of hanging indefinitely; its [script header](../bin/fm-on.sh) owns the keepalive defaults and environment overrides.
+### SSH access from the primary
+
+1. Configure an SSH alias in the primary account's normal OpenSSH configuration.
+2. Use ordinary public-key authentication, strict host-key verification, and a dedicated remote account where practical.
+3. Do not enable agent forwarding for Firstmate.
 
-Clone Firstmate on the remote host at an absolute code-root path.
-Expose that clone's fixed entrypoint on the account's non-interactive SSH `PATH`, for example:
+`fm-on.sh` adds its own protections:
+
+- On every call, it also disables agent forwarding, forwarding setup, and configured `SendEnv` patterns.
+- It arms bounded SSH dead-peer detection, so a vanished host (a reboot, a dropped link) fails within a bounded window instead of hanging indefinitely.
+
+Its [script header](../bin/fm-on.sh) owns the keepalive defaults and environment overrides.
+
+### Remote clone and entrypoint
+
+1. Clone Firstmate on the remote host at an absolute code-root path.
+2. Expose that clone's fixed entrypoint on the account's non-interactive SSH `PATH`, for example:
 
 ```sh
 mkdir -p ~/.local/bin
@@ -27,35 +58,127 @@ ln -s /absolute/path/to/firstmate/bin/fm-remote-entrypoint.sh ~/.local/bin/fm-re
 
 The entrypoint accepts encoded argv for genuine executable `bin/fm-*.sh` files only.
 It never accepts a shell command string.
-The readiness-owning doctor runs over this plain SSH bootstrap so read-only mode can report worker gaps and `--fix` can install or repair the worker.
-The entrypoint authorizes that bootstrap with normal git tracking when git resolves and with its pinned doctor digest when doctor must report that git itself is missing.
-After setup, every other command verifies Firstmate's account-owned remote job worker, stages the encoded argv and stdin bytes, waits for its result, and relays stdout, stderr, and the exit status separately.
+
+### Doctor bootstrap over plain SSH
+
+The readiness-owning doctor runs over this plain SSH bootstrap.
+That lets read-only mode report worker gaps and lets `--fix` install or repair the worker.
+The entrypoint authorizes that bootstrap in one of two ways:
+
+- With normal git tracking when git resolves.
+- With its pinned doctor digest when doctor must report that git itself is missing.
+
+### The remote job worker
+
+After setup, every other command goes through Firstmate's account-owned remote job worker.
+Each such command takes these steps:
+
+1. It verifies the worker.
+2. It stages the encoded argv and stdin bytes.
+3. It waits for its result.
+4. It relays stdout, stderr, and the exit status separately.
+
 On macOS the worker is `dev.firstmate.remote-job`, an Aqua-scoped LaunchAgent at `~/Library/LaunchAgents/dev.firstmate.remote-job.plist` with logs under `~/Library/Logs/`.
-After that bootstrap every non-doctor `fm-on.sh` target runs through that worker in the remote account's GUI session, never in the SSH process or a Herdr pane.
-The worker serves one lane per staged home: jobs for the same home follow the staging-order contract owned by [`bin/fm-remote-job-lib.sh`](../bin/fm-remote-job-lib.sh), while different homes' lanes run concurrently so one home's long job never delays another home's commands.
-Within a home's lane the worker preempts a running reply long-poll as soon as any command other than another reply long-poll is queued for that home, so interactive commands and startup checks are never serialized behind a poll window.
-`bin/fm-remote-job-lib.sh` owns that preemption contract and distinguishes preemption from a wait window that closes with no data, so only a genuinely quiet window proves channel freshness while either outcome can re-arm without losing data.
-A caller that disconnects or whose caller-side wait expires before its job completes cancels it instead of abandoning it: cancelled queued work is skipped, cancelled running work is stopped, and the finalized record is cleaned up, so retries never convoy behind abandoned work.
+After that bootstrap, every non-doctor `fm-on.sh` target runs through that worker in the remote account's GUI session.
+It never runs in the SSH process or a Herdr pane.
 Linux uses the same queue and worker protocol without the Aqua-session requirement.
-A worker stops itself once its configured code root stops being a Firstmate checkout, so a worker started from a worktree cannot outlive that worktree, and `bin/fm-remote-job-reap-orphans.sh` clears any worker already left behind that way without ever touching one whose checkout still exists.
-The remote account must provide the required toolchain, the selected worker runtime, the selected session backend, and credentials that work on that host.
-A [worker account pin](configuration.md#worker-account-pin-configclaude-account-configpi-account) for the second mate or its workers lives in the remote home's own configuration on that host.
-The origin URL named for each project must be reachable from the remote account because projects are cloned on that host rather than copied from the primary.
+
+### Job lanes and preemption
+
+The worker serves one lane per staged home:
+
+- Jobs for the same home follow the staging-order contract owned by [`bin/fm-remote-job-lib.sh`](../bin/fm-remote-job-lib.sh).
+- Different homes' lanes run concurrently, so one home's long job never delays another home's commands.
+
+Within a home's lane, the worker preempts a running reply long-poll as soon as any command other than another reply long-poll is queued for that home.
+As a result, interactive commands and startup checks are never serialized behind a poll window.
+
+`bin/fm-remote-job-lib.sh` owns that preemption contract.
+It distinguishes preemption from a wait window that closes with no data:
+
+- Only a genuinely quiet window proves channel freshness.
+- Either outcome can re-arm without losing data.
+
+### Cancelled and orphaned jobs
+
+A caller cancels its job instead of abandoning it when, before the job completes, the caller disconnects or its caller-side wait expires:
+
+- Cancelled queued work is skipped.
+- Cancelled running work is stopped.
+- The finalized record is cleaned up.
+
+As a result, retries never convoy behind abandoned work.
+
+A worker stops itself once its configured code root stops being a Firstmate checkout, so a worker started from a worktree cannot outlive that worktree.
+`bin/fm-remote-job-reap-orphans.sh` clears any worker already left behind that way.
+It never touches a worker whose checkout still exists.
+
+### What the remote account must provide
+
+- The remote account must provide the required toolchain, the selected worker runtime, the selected session backend, and credentials that work on that host.
+- A [worker account pin](configuration.md#worker-account-pin-configclaude-account-configpi-account) for the second mate or its workers lives in the remote home's own configuration on that host.
+- The origin URL named for each project must be reachable from the remote account, because projects are cloned on that host rather than copied from the primary.
 
 ## Non-interactive tool contract
 
-Remote job execution never runs a login or interactive shell, so `~/.profile`, `~/.bashrc`, and `~/.zshrc` never contribute to the job worker's runtime `PATH`.
-`bin/fm-remote-job-lib.sh` is the single owner of the worker `PATH` and builds it by filesystem discovery rather than by evaluating shell startup files.
-The authorized child sees `<remote-root>/bin` first, then a genuine account `~/.local/bin`, the nvm default version bin, asdf shims and install bins, mise shims and install bins, Nix directories, Homebrew directories, and the system tail `/usr/bin:/bin:/usr/sbin:/sbin`.
-Nvm selection follows the filesystem `alias/default` chain and chooses the highest matching installed semantic version, falling back to the highest installed semantic version when the alias is absent or has no installed match.
-An nvm `system` default adds no nvm version bin, so the later system directories provide Node.
-The Nix and package-manager order after version-manager discovery is `~/.nix-profile/bin`, `/etc/profiles/per-user/<account>/bin`, `/run/current-system/sw/bin`, `/opt/homebrew/bin`, and `/usr/local/bin`.
+Remote job execution never runs a login or interactive shell.
+So `~/.profile`, `~/.bashrc`, and `~/.zshrc` never contribute to the job worker's runtime `PATH`.
+`bin/fm-remote-job-lib.sh` is the single owner of the worker `PATH`.
+It builds the `PATH` by filesystem discovery rather than by evaluating shell startup files.
+
+### Worker PATH order
+
+The authorized child sees these directories, in this order:
+

+### nvm version selection
+
+Nvm selection follows the filesystem `alias/default` chain and chooses the highest matching installed semantic version.
+When the alias is absent or has no installed match, it falls back to the highest installed semantic version.
+An nvm `system` default adds no nvm version bin, so the later system directories provide Node.

+### Symlinked directories
+
+For the three Nix locations:
+
+- A final `bin` symlink is resolved to its physical directory.
+- A path reached through symlinked ancestors remains in its documented position.

 Other final-component symlink directories, including `~/.local/bin`, are excluded.
-Because `~/.local/bin` precedes the package-manager directories, a stale self-updated `herdr` there shadows the one the account's login shell may resolve; the Herdr adapter steps around a client the running server refuses and `fm-remote-doctor.sh` names which client it selected ([`herdr-backend.md`](herdr-backend.md#client-selection)).
-The entrypoint resolves `git` only from the operator portion before prepending `<remote-root>/bin` for the authorized child.
-A checkout-local `bin/git` therefore cannot authorize an untracked command, and a host with no operator `git` receives an install-or-wrapper diagnostic before command execution.

+
+### How the entrypoint resolves git
+
+The entrypoint resolves `git` only from the operator portion of the `PATH` (every discovered directory except `<remote-root>/bin`).

-The Herdr agent runs [`bin/fm-remote-herdr-guard.sh`](../bin/fm-remote-herdr-guard.sh) through a shell in login mode with separate `-l` and `-c` arguments, resolving the remote account's executable labeled Directory Services `UserShell`, then an executable `$SHELL`, and finally `/bin/sh`, so the server inherits the account's own environment.

-Herdr's own SSH remote attach starts such a server when it finds none, and at boot it wins the `fm-remote` socket because sshd accepts connections before the login session exists, so the guard is what makes the launch agent converge: it execs the server in the foreground under launchd when nothing owns the socket, exits 0 when an Aqua-born server already does, and otherwise stops the foreign server and takes the session over, closing its panes so the parent firstmate relaunches its mates into the Aqua-born server.

+Over the plain SSH doctor bootstrap, it writes and reloads two Firstmate-owned launch agents on macOS:

+Both are scoped with `LimitLoadToSessionType=Aqua` and bootstrapped in `gui/<uid>`.
+
+### How the Herdr launch agent starts its server
+
+The Herdr agent runs [`bin/fm-remote-herdr-guard.sh`](../bin/fm-remote-herdr-guard.sh) through a shell in login mode with separate `-l` and `-c` arguments.
+It resolves that shell in this order, so the server inherits the account's own environment:

+2. An executable `$SHELL`.
+3. `/bin/sh`.

+Every claude pane under such a server falls back to a stale plaintext credentials file and reports "Login expired".
+
+### How the guard converges on one server
+
+Herdr's own SSH remote attach starts a server born in another session when it finds none.
+At boot, that server wins the `fm-remote` socket, because sshd accepts connections before the login session exists.
+The guard is what makes the launch agent converge.
+It acts on whichever server owns the `fm-remote` socket:
+
+| Socket owner | Guard action |
+| --- | --- |
+| Nothing | Execs the server in the foreground under launchd. |
+| An Aqua-born server | Exits 0. |
+| Any other (foreign) server | Stops the foreign server and takes the session over, closing its panes so the parent firstmate relaunches its mates into the Aqua-born server. |
+
+`KeepAlive={SuccessfulExit=false}` lets that exit 0 rest instead of respawning against a held socket.
+The guard's header owns the decision table, and [`bin/fm-remote-herdr-owner-lib.sh`](../bin/fm-remote-herdr-owner-lib.sh) owns the birth markers it reads.
+
+### Other repairs and limits

+- It starts the same workers directly on Linux.
+- It recreates the `~/.local/bin/fm-remote-entrypoint.sh` symlink when it is absent.
+- It creates only Firstmate-owned required-tool wrappers that it can prove resolve to a version-manager target.

+
+Its limits:

+- It never installs packages or overwrites a non-Firstmate file at a reserved wrapper path.

+
+### Steps only a person can take
 
 These steps are never automated and are always reported rather than silently attempted, because SSH cannot create a GUI session from nothing:
 
 - The first console login on that Mac, and automatic login in System Settings > Users & Groups when the machine runs headless and must come back on its own after a reboot.
 - FileVault, which holds a reboot at pre-boot authentication before any login session exists.
 - Installing any missing required tool that no safe wrapper can resolve.
-- The required remote tool set is `git`, `jq`, `herdr`, compatible `tasks-axi`, `treehouse`, and at least one of `claude`, `codex`, `opencode`, `pi`, `pi-signed`, `grok`, or `kimi`; macOS additionally requires `lsof` so the doctor and guard can prove which process owns the session socket.
 - Each worker runtime's own `/login`, and any keychain password prompt that login needs.
 
 Firstmate never writes an auto-login password, never changes FileVault, and never stores an account password.
 A file at `~/.local/bin/fm-remote-entrypoint.sh` that is not Firstmate's own symlink is reported for the operator to inspect and is never overwritten.

-In the primary home, its durable registration effects are limited to that route and the charter brief under `data/<id>`; launch records are created only when the secondmate is launched.
-Readiness starts with a read-only check; when that check reports a gap, it runs `--fix` and then a second read-only check whose verdict decides, so the operator never has to run the repair by hand and a repair is never trusted on its own word.
-A host that stays red prints the doctor's remaining gaps and their operator steps, restores the registry, and creates nothing on the remote host.

+2. It gates the host on readiness.
+3. It sends a bounded manifest.
+4. It lets the remote host clone its own Firstmate home and project origins.
+
 It does not copy project trees or the primary process environment.
-A known provisioning failure rolls back the new route, while SSH exit 255 preserves it because remote completion is unknown and must be reconciled on the same host.
+In the primary home, its durable registration effects are limited to that route and the charter brief under `data/<id>`.
+Launch records are created only when the secondmate is launched.
+
+### The seed's readiness gate
+
+The seed gates readiness in these steps:
+
+1. The seed runs a read-only check.
+2. When that check reports a gap, it runs `--fix`.
+3. It then runs a second read-only check, whose verdict decides.

+So the operator never has to run the repair by hand, and a repair is never trusted on its own word.

+
+### Replay identity
+
 Each normalized source line, before its delivered `report=` pointers are rewritten, is the replay identity.
-Once committed, that identity prevents an ingestion retry or whole-log recapture from appending a second spelling when document availability changes, and its record survives reply-adapter retirement alongside the parent status stream.
+Once committed, that identity prevents an ingestion retry or whole-log recapture from appending a second spelling when document availability changes.
+Its record survives reply-adapter retirement alongside the parent status stream.
+
 For lines mirrored before this source-line record existed, exact mirrored bytes remain the compatibility fallback.
-The first whole-log recapture after upgrading can therefore append one duplicate in the original source spelling for a legacy line whose bare `data/*.md` mention was previously fetched and rewritten; if that line was a since-resolved decision, the duplicate can read as reopening it, but recording that source line prevents another duplicate on later recaptures.
-The channel carries the mate's status and decision model: an uncorrelated progress line and a newly raised `needs-decision` travel the same path as a correlated answer, and reach the parent's open-decision fold identically.
-Correlation is a per-line property that settles a pending request; it is never a gate on the stream, so no single line can stop or wedge the relay or hold the cursor back.
-Transport normalization rewrites NUL, every other C0 control except tab and newline, and DEL to `?`, while printable ASCII and all high bytes, including UTF-8, pass through unchanged.
-If the confined remote reader cannot deliver an offered document, the channel fails open: the mate's line is mirrored with its original pointer, the cursor still advances, and the adapter appends one unkeyed note carrying the reader's own reason instead of stalling the stream.
-That note never enters the open-decision fold, because the reader cannot tell a report that is still being written from one that will never exist, and a decision raised on that ambiguity could stand open describing a transfer that later succeeded.
-A refused document is not re-attempted automatically; it stays on the remote, and a later structured offer of the same path fetches it.
-An SSH exit status of 255 while fetching a referenced document leaves the delta uncommitted for the process-event runner's normal retry because remote completion is unknown.
-The process-event runner applies each captured delta through this adapter as soon as it is captured, so a mirrored reply reaches the primary status channel without depending on the wake handler running the adapter itself.

+It is never a gate on the stream, so no single line can stop or wedge the relay or hold the cursor back.
+
+### Transport normalization
+
+| Bytes | Result |
+| --- | --- |
+| NUL, every other C0 control except tab and newline, and DEL | Transport normalization rewrites them to `?`. |
+| Printable ASCII and all high bytes, including UTF-8 | They pass through unchanged. |
+
+### When an offered document cannot be fetched
+
+If the confined remote reader cannot deliver an offered document, the channel fails open instead of stalling the stream:
+
+- The mate's line is mirrored with its original pointer.
+- The cursor still advances.
+- The adapter appends one unkeyed note carrying the reader's own reason.
+
+That note never enters the open-decision fold, because the reader cannot tell a report that is still being written from one that will never exist.
+A decision raised on that ambiguity could stand open describing a transfer that later succeeded.
+
+A refused document is not re-attempted automatically.
+It stays on the remote, and a later structured offer of the same path fetches it.
+An SSH exit status of 255 while fetching a referenced document leaves the delta uncommitted for the process-event runner's normal retry, because remote completion is unknown.
+
+### Reply settlement
+
+The process-event runner applies each captured delta through this adapter as soon as it is captured.
+So a mirrored reply reaches the primary status channel without depending on the wake handler running the adapter itself.
 A mirrored line that carries a correlation token settles its pending-reply record and closes that request's own open escalation decision.
-Because a remote reply reaches the primary only through this asynchronous mirror, the primary treats a missing correlated report as a missed report only once the mirror has been read through the end of the remote log after that turn ended.
-A remote mate that did answer is therefore never asked to repost while its answer is still in flight, and a genuinely missing answer still gets exactly one repost once the mirror is known to be current.

Subject: [PATCH 18/84] fix(bin): bound the away digest and log why a delivery
 failed (#5554)

* fix(bin): bound the away digest and log why a delivery failed

The away daemon joined every buffered escalation into one unbounded
digest. A start-up catch-all span can exceed what one transport argument
carries (tmux rejects the send-keys command; Linux refuses to exec any
argument above 131,071 bytes, which is how herdr receives it), so the
initial send failed on every housekeeping pass and was logged as an
unconfirmed Enter with text possibly in the composer.

escalate_flush now builds the injected digest under a fixed byte budget:
each event is cut at a UTF-8 boundary with an omitted-bytes marker, the
joined events stop with a "+K more event(s)" tail, and a bounded digest
names a state/.subsuper-digests/ file that keeps every buffered event
verbatim. The buffer itself is untouched, so the return catch-up stays
complete.

The tmux submit core and the herdr literal send now replay the
transport's stderr on failure, and inject_msg logs the failing stage
(initial send versus Enter confirmation) with the byte count and that
stderr. The wedge alarm line and marker carry the last failure reason.

Fixes #4382

* no-mistakes(review): Drop digest pruning; label send-failed as send-or-Enter stage

* no-mistakes(review): Keep digest full text once submit ran; reuse on retry

* no-mistakes(lint): Count digest files with find instead of ls

 The daemon wraps `fm-watch.sh`, runs the watcher as a child, presents every durable wake after each actionable watcher close, classifies each presented record in bash, and acknowledges the presented generation only after routing completes.
 It self-handles the routine majority without consuming a firstmate turn.
 Captain-relevant events, plus a bounded recheck of a declared external wait that is still declared, escalate to firstmate's context as one pre-read, single-line, batched digest.
+The digest is byte-bounded so every transport can carry it; when it cuts an event or omits events past its budget, it names a `state/.subsuper-digests/` file that holds every buffered event verbatim, so read that file before acting on a cut event.
 The captain-relevant verb set, declared-wait vocabulary, status-span classifier, and presentation-marker contract live in shared `bin/fm-classify-lib.sh`, while each supervisor owns its routing and fleet scan as a consumer of that policy.
 While `state/.afk` exists the daemon owns the watcher, so the watcher reverts to one-shot and lets the daemon do the triage - the two never run their triage at the same time.

Subject: [PATCH 19/84] test: add a gated harness seam and stabilize lifecycle
 fixtures (#5638)

* feat(tests): add FM_TEST_SEAM launch seam and gate lab-primary recipe

Part 1 of the #5615 split: the pieces that let the no-mistakes pipeline
live-validate firstmate changes, without the gate-refusal rescoping.

- bin/fm-afk-launch.sh: FM_TEST_HARNESS pins the detected harness only
  alongside the FM_TEST_SEAM=1 marker test suites set, so a leaked variable
  in a real primary's environment stays inert and unknown tokens fall
  through to real detection.
- tests/lib.sh: export FM_TEST_SEAM=1 for every suite.
- .no-mistakes.yaml: per-harness recipe for running a real fixture primary
  from a gate run - a plain mktemp lab FM_HOME on a private tmux socket,
  with FM_GATE_REFUSE_BYPASS=1 scoped to it and NO_MISTAKES_GATE scrubbed.
- tests/fm-wake-queue.test.sh: stop the owned watcher fixture with KILL and
  clear its lifecycle state so the next leg starts clean; TERM could leave
  bash waiting in a child on some runners.
- tests/fm-remote-secondmate-lifecycle-e2e.test.sh: wait for the liveness
  lock holder's post-acquire marker instead of the lock dir, which is
  published before the claim finishes.

* no-mistakes(review): Scrub lab home overrides and require FM_TEST_SEAM separately

* no-mistakes(document): Clarify test seam and disposable lab bypass documentation

* no-mistakes(document): Clarify lab isolation and test-seam documentation

* no-mistakes(ci): Fixed the CI failure: test cleanup killed the remote worker child but left its supervisor able to restart it during fixture removal. Cleanup now stops the worker tree. The lifecycle test passed locally; ShellCheck and diff checks passed

     Run live Herdr scenarios only through bin/fm-herdr-lab.sh with a named non-default fm-lab-* session, following that helper's prepare, provision, run, and teardown contract exactly.
     Never touch the live default Herdr session or fleet panes.
     Prefer a throwaway lab for spawn, long-launch, and Claude-path proofs, and tear it down in the same evidence turn.
-    Lifecycle calls against a throwaway firstmate home proceed inside the gate only when the home was minted by `bin/fm-lab-home.sh create <dir>` and driven as plain `FM_HOME=<dir>` with no FM_*_OVERRIDE relocations; every other home stays refused.
+    To run a real primary inside the gate, mint a disposable lab home: `LAB=$(mktemp -d "${TMPDIR:-/tmp}/fm-lab.XXXXXX")` then `bin/fm-lab-home.sh create "$LAB"` and `mkdir -p "$LAB/tmux"`; write the scenario's opt-in flag (e.g. `touch "$LAB/config/supervision-host"`), and remove the lab in the same evidence turn with `rm -rf "$LAB"`. Lifecycle calls against any other home stay refused.
+    Start the harness CLI as the session command on the lab's private tmux socket, from the run worktree: `env -u NO_MISTAKES_GATE -u FM_GATE_REFUSE_BYPASS -u FM_ROOT_OVERRIDE -u FM_STATE_OVERRIDE -u FM_DATA_OVERRIDE -u FM_CONFIG_OVERRIDE -u FM_PROJECTS_OVERRIDE TMUX_TMPDIR="$LAB/tmux" tmux -L fm-lab new-session -d -s primary -c "$PWD" -e FM_HOME="$LAB" <cli>`, where <cli> is the harness's own launch command using the machine's existing login: claude -> `claude`, codex -> `codex`, cursor -> `cursor-agent`, opencode -> `opencode`, grok -> `grok`, omp -> `omp`. Drive, inspect, and stop that primary only through the same socket - `TMUX_TMPDIR="$LAB/tmux" tmux -L fm-lab send-keys -t primary ...`, `TMUX_TMPDIR="$LAB/tmux" tmux -L fm-lab capture-pane -p -t primary`, `TMUX_TMPDIR="$LAB/tmux" tmux -L fm-lab kill-server` - never the default tmux server; the firstmate scripts the primary runs inherit $TMUX from its pane, which names that same fm-lab socket inside the lab. The lab primary's scripts run from the gate worktree, whose git-common-dir triggers the gate check, and the marked lab home permits lifecycle without a bypass; the `env -u` list keeps inherited fleet-path overrides out of the fixture primary's environment so all paths resolve inside the lab. For a Herdr primary use a named non-default fm-lab-* session via bin/fm-herdr-lab.sh instead. If the harness CLI is absent or its login is unavailable, report the scenario untested; never fake the CLI, the login, or the evidence.
     Do not mutate the operator primary checkout, real fleet FM_HOME state, or production credentials, and keep git changes otherwise inside the run worktree.
     Read docs/herdr-backend.md and the bin/fm-herdr-lab.sh header as the owners of Herdr lab mechanics rather than reproducing that manual here.
     Ship or scout briefs that will drive Herdr lifecycle still require --herdr-lab at scaffold time; these Test-agent instructions are not a substitute for that brief flag.

Subject: [PATCH 20/84] fix(bin): refuse watchers from disposable checkouts and
 exit when the home is gone (#5552)

* fix(bin): refuse watchers from disposable checkouts and exit when the home is gone

Fixes #321
Fixes #4760

A watcher armed from a disposable no-mistakes validation checkout under
.no-mistakes/worktrees/ outlived the validation step and kept writing the
real home's state, and a running watcher never noticed when its home,
state directory, or code root disappeared. The arm now refuses from such
a checkout with the typed failure line, the watcher checks once per poll
that its home, state directory (or its own lock holder record), and bin
directory still exist and exits with a logged reason scoped to itself,
and the shared test helpers reap every watcher a suite armed for a
temporary home through the home-scoped stop.

* no-mistakes(lint): fix SC1007 by assigning empty string in watch-arm test

* no-mistakes(ci): Found and fixed a genuine, reproducible hang introduced by this branch's test-watcher reaper, which is what killed both CI checks (serial-2 cancelled at the 30-min cap; Lint 2 exit 143 = the suite's own TERM-trap code). Root cause: test_drain_asserts_watcher_liveness (tests/fm-wake-queue.test.sh) fabricates a .watch.lock whose pid is the test runner's own $$ with the runner's real identity, to make the drain believe a live watcher exists. The new make_case tracking registers that state dir for reaping, so at fm_test_cleanup the new fm_test_reap_watchers drives fm-watch-arm.sh --stop; its identity check matches (the fixture recorded the runner's identity) and it kill -TERMs the test runner. tests/lib.sh:231 is `trap 'fm_test_cleanup; exit 143' TERM`, so the TERM re-enters cleanup -> reap -> kills $$ again -> infinite loop until the runner cap. I reproduced this locally: the suite ran all tests then looped forever in cleanup spawning fm-watch-arm.sh --stop against a lock naming its own PID. Fix (tests/lib.sh, +5 lines): in fm_test_reap_watchers, skip any tracked lock whose pid equals our own $$ before driving --stop. This is the single shared reap boundary; seven $$-self-lock fixtures across four test files are all covered by the one guard, and real armed watchers (pid != $$) are still reaped. Invariant: the test reaper must only signal real armed watcher processes, never the test runner itself. Verified locally: tests/fm-wake-queue.test.sh -> EXIT 0 (63 ok, no hang); tests/fm-watch-arm.test.sh -> EXIT 0 (21 ok, including test_reaper_stops_a_tracked_watcher, confirming the guard does not over-skip). Lint 2's exit 143 was the same shard/cap signature; a fresh CI run on this new commit will re-evaluate it

Subject: [PATCH 21/84] fix(bin): surface unrecognized status prefixes instead
 of reading them as silence (#5588)

* fix(bin): surface an unrecognized status prefix instead of dropping it

A parked or holding declaration, and a verb whose correlation token did not parse, never became an event, so the supervisor still saw the earlier line.

* no-mistakes(review): Require verb-shaped unrecognized status prefixes, add continuation tests

* no-mistakes(document): Document unrecognized status prefix escalation in afk skill

* no-mistakes(ci): I reproduced the "Behavior portable serial 6" failure locally and fixed it by changing the test data in one test. No product code changed. **What failed:** `tests/fm-session-start.test.sh`, in `test_orphan_status_logs_are_printed`, with "matched status log was printed 2 times". **Why:** the test writes status lines with made-up prefixes, `matched: surfaced once` and `orphan: step N`. The test only uses them as placeholder text. It checks that the session-start digest prints each task's status tail exactly once. This PR (#4763) deliberately makes an unrecognized one-word lowercase prefix a status event. So those lines now surface as captain-relevant events, and the wake queue's STATUS OUTCOME BACKSTOP section prints them a second time. The code under review is behaving as the issue asks. Only the test's placeholder data had become meaningful. **Rule the test depends on:** its status lines must not be captain-relevant, so the digest is the only place they are printed. Both lines in this test broke that rule. The orphan line would have failed the same count check right after the matched line did. **Fix:** in that test only, I switched both lines to the recognized, non-captain verb `working:`: `working: surfaced once` and `working: orphan step 1..6`. I updated the matching assertions and counts to use the new text. What the test checks is unchanged: orphan logs are labelled, the tail is bounded, the log path is printed, and each tail appears once. **Verification:** before the fix, the test failed locally the same way as in CI. After it, `bash tests/fm-session-start.test.sh` reports "all assertions passed

* no-mistakes(review): Detect unrecognized prefixes on unstamped lines; share verb list

 A presence-gated sub-supervisor (`bin/fm-supervise-daemon.sh`) still extends walk-away supervision on the remaining harnesses: the `/afk` skill starts it through the tracked foreground helper `bin/fm-afk-start.sh` once the record exists, after which the watcher reverts to daemon-managed one-shot mode and the daemon self-handles routine wakes in bash.
 The watcher and daemon share `bin/fm-classify-lib.sh` for captain-relevant status verbs, declared-wait vocabulary (a `paused:` external wait and a verified `captain-held` transfer alike, through one combined predicate), and status-scan primitives.
 Terminal verbs remain captain-relevant, while a nonterminal progress verb cannot become terminal merely because its prose contains a legacy free-text token such as `merged`; bare legacy free-text lines remain compatible.
-The shared latest-event read takes the most recent line that leads with a recognized verb or legacy token, so continuation prose and trailing blank lines after a multi-line record cannot hide a declared wait.
+The shared latest-event read takes the most recent line that leads with a recognized verb, a legacy token, or an unrecognized status prefix, so a bad declaration stays visible as itself while continuation prose and trailing blank lines after a multi-line record cannot hide a declared wait.
 Both supervisors decide a declared wait through the library's declared-wait read rather than that latest event, so a later `resolved` line for a different phase key - including an `fm-send --resolve-key default` answer to a keyless decision - does not end a standing keyless or keyed `paused:` wait, while a resolved line for the wait's own key or any other later event still does.
 Both supervisors classify the status bytes appended since they last classified that log, never its last line alone, and report every actionable event through the captured endpoint before committing that position.
 The watcher's `.seen-*` and `.hb-surfaced-<task>` markers and the daemon's `.subsuper-seen-status-<task>` marker independently track reported file state and successfully classified position, so an unchanged unreadable state reports once without advancing past unread content, while a changed state retries and an unusable position re-reads the whole log.

Subject: [PATCH 22/84] fix(bin): report the failing item when remote
 inheritance fails (#5658)

Fixes #5295

Session start now reports a remote inheritance failure using the
push's own error line instead of the first unchanged item that
happened to print before it, and the shared captain preferences
header check now names the first required phrase it did not find,
on both the local and remote inheritance paths.

Subject: [PATCH 23/84] fix(bin): stand down the Claude Stop auto-arm on
 pi-code-delivered payloads (#5657)

* fix(bin): stand down the Claude Stop auto-arm on pi-code-delivered payloads

pi-code loads the tracked Claude settings but has no asyncRewake, so it
awaits every Stop hook; without a stand-down the auto-arm runs
synchronously inside Pi's turn end and holds it open for the declared
multi-hour timeout. Stand down when the payload's transcript_path
contains a /.pi/ path component, the same discriminator the closed-but-
unmerged fix in #3352 used, with an explicit string-type check on the
jq filter.

Fixes #3343

 Claude and Codex can block a Stop directly with exit status 2 and stderr.
 Both payloads carry `stop_hook_active`.

Subject: [PATCH 24/84] fix(bin): match whole multi-word project names in the
 registry lookup (#5659)

* fix(bin): match whole multi-word project names in the registry lookup

bin/fm-project-mode.sh matched a registered project name against only the
first whitespace-delimited token of a registry row, so a name containing a
space never matched, silently defaulting the project to no-mistakes off
instead of its declared posture.

The lookup now matches the whole registered name against the raw line text,
so a name is compared literally (never as a regex) and a name that is a
leading prefix of another registered name still resolves to its own row.

* no-mistakes(document): docs already accurate for multiword registry name match

* chore: drop accidental empty err file

Subject: [PATCH 25/84] fix(bin): classify shell stdin payloads after -s
 operands (#5546)

* fix(bin): classify the stdin program of `bash -s` with operands in the arm policy

With -s, sh/bash/zsh read the program from stdin even when operands follow;
the operands are only positional parameters. The arm policy treated the first
operand as a script path, so heredoc and here-string payloads were never
classified and a hidden bin/fm-watch.sh execution was allowed.

A protected path in the operand position still fails closed as before.

Fixes #1489

* no-mistakes(document): Clarify stdin shell operand documentation

* no-mistakes(ci): Captain, fixed `shellInvocation` so `bash -- -s` treats `-s` as a script name, and updated R21 to test the exact command. The targeted policy suite, lint, documentation check, and diff check pass. Both hosted workflows show `action_required` before any jobs ran; that external approval state remains unresolved

* fix(bin): keep main's handling of words after a leading `--`

Revert the pipeline CI-step change that made the first word after a leading
`--` always a script. It turned forms that main denies today into allow
(for example `bash -- -c 'bin/fm-watch.sh'`), which is outside #1489 and
loosens a fail-closed policy. `--` after `-s` still ends option parsing.

Subject: [PATCH 26/84] fix(bin): strip AI co-author trailers from
 fleet-launched commits (#5695)

* fix(bin): strip AI co-author trailers from fleet-launched commits

Cursor and other non-Claude runtimes append the trailer after the typed
message. A per-task commit-msg hook removes it and leaves human co-authors
and the author identity untouched.

* no-mistakes(review): Export pane hooksPath override and drop generated-with stripping

* no-mistakes(ci): This PR caused all three CI failures, and the fix is test-only: 4 test files change, no product code. **Cause.** `fm-spawn.sh` now installs the AI-trailer strip hooks for every spawn, secondmates included. The installer refuses a worktree that is not a git repository, and the PR deliberately keeps that fail-closed rule because real secondmate homes are firstmate clones. Four test fixtures still gave secondmates a plain directory as their home, so each spawn failed with "not a git worktree ... could not install the AI-trailer strip hooks": - serial 5: `tests/fm-backlog-atomicity.test.sh` ("secondmate spawn failed"). - serial 8: `tests/fm-secondmate-harness.test.sh` ("split: no meta written"). - Herdr: `tests/fm-backend-herdr-launcher-workspace-e2e.test.sh` and `tests/fm-backend-herdr-workspace-per-home-e2e.test.sh`. **Rule that must hold.** Every home a test spawns as a secondmate must be a git worktree. I checked the other places in the changed area: the only secondmate spawns in these tests are the ones listed. The earlier rounds already fixed the other fixtures (`fm-secondmate-liveness`, `fm-secondmate-safety`) the same way. **Fix.** - Each of those four secondmate homes now gets the same `.gitignore` plus `git init -q -b main` that the liveness and safety tests already use. - The two Herdr tests clean up with their own plain `rm -rf "$TMP_ROOT"`, not the shared `tests/lib.sh` helper. Because the installer leaves each `state/<id>.git-hooks` directory read-only, that cleanup printed "Permission denied" and left the directories behind. Both cleanups now restore the owner's write bit on every directory before removing (`find ... -exec chmod u+rwx`), which is what `fm_test_remove_tree` in `tests/lib.sh` does. **Verification.** - `tests/fm-secondmate-harness.test.sh` passes. - `tests/fm-backlog-atomicity.test.sh` passes (99 ok, exit 0). - shellcheck is clean on all four files. - I could not run the two real-Herdr tests locally: the Herdr lab on this host refuses to start because it needs exactly one running default session, and I did not change the host's Herdr state to get around that. Instead I checked their two changed steps directly: the installer succeeds on a home set up the new way, and the new cleanup removes the read-only hooks directory completely. Those two tests will only be proven on CI

+#       which are deliberately excluded (see FM_GIT_CLIENT_HOOKS below).
+#       Each wrapper unsets GIT_CONFIG_* and then resolves

+#       prefixes the pane with GIT_CONFIG_COUNT / GIT_CONFIG_KEY_0 /
+#       GIT_CONFIG_VALUE_0.

+# WHY THIS EXISTS. Claude launches already carry attribution-off in their
+# per-launch --settings JSON. Cursor and other non-Claude runtimes inject a
+# Co-Authored-By trailer at the tooling layer AFTER the worker types a clean
+# message, so the typed message is not the commit object.
+# A prior per-machine ~/.cursor/cli-config.json attribution-off is not durable:
+# it does not travel with Firstmate, it defaults back to on when unset, and it
+# only feeds the CLI's request to the server - the trailer text is emitted by
+# the model, so the setting suppresses rather than prevents it. Verified live
+# on cursor-agent 2026.09.15 with attribution on: the trailer is already in
+# .git/COMMIT_EDITMSG when the commit-msg hook runs, so the spawn-owned hook is
+# the layer that sees the assembled message before the commit object is written.
+# Human Co-Authored-By trailers are left untouched. Author identity is not
+# rewritten.
+#
+# ACCEPTED RESIDUAL, ruled 2026-09-17. git commit --no-verify skips every hook,
+# so a worker that passes it still lands the trailer, as would a runtime that
+# writes the commit object without running git. Both incidents that motivated
+# this strip came through an ordinary hook-running commit, so the ruling is to
+# accept that gap rather than add a push-side rewrite or a push-side check. A
+# trailer found on a fleet commit therefore points at one of those two paths,
+# not at an unnoticed hole in the matcher.
+#
+# ACCEPTED RESIDUAL, ruled 2026-09-17. Inside a fleet pane git reports this
+# directory as the repository's hooks directory, so a hook manager run there
+# (lefthook's npm postinstall, pre-commit install) targets it and would
+# displace the strip. install leaves the directory and every hook in it
+# read-only, so such a manager fails loudly instead of silently winning. Hook
+# managers therefore cannot install from inside fleet panes until a registered

 [`fm-spawn.sh --help`](../bin/fm-spawn.sh) owns the delivery mechanics, with focused regression coverage in [`tests/fm-spawn-compact-adviser-disable.test.sh`](../tests/fm-spawn-compact-adviser-disable.test.sh) and [`tests/fm-spawn-compact-adviser-disable-remote.test.sh`](../tests/fm-spawn-compact-adviser-disable-remote.test.sh).
 
 Every claude launch's inline `--settings` JSON also carries `"attribution":{"commit":"","pr":"","sessionUrl":false}`, so a spawned worker never writes a Co-Authored-By trailer, Claude-Session link, or generated-with line into a commit or PR body regardless of which settings scopes end up loaded.
+Every fleet launch, Claude included, also receives a pane-scoped `GIT_CONFIG` `core.hooksPath` pointing at `state/<id>.git-hooks`, so git's `commit-msg` hook strips known AI trailers at the commit object even when a runtime injects them after the typed message.
+`bin/fm-git-strip-ai-trailers.sh` owns the identities, the install, and chaining the hooks of whichever repository git is running in, so a project hook such as husky still runs.
+That directory is read-only, so a hook manager run inside a fleet pane (lefthook's npm postinstall, `pre-commit install`) fails instead of displacing the strip; install a project's hooks from outside the pane, where the wrappers chain them.
+Per-machine Cursor `cli-config.json` attribution-off is not this contract: it does not travel with Firstmate, defaults back to on when unset, and only feeds the CLI's request to the server, so it suppresses the trailer rather than preventing it.

Subject: [PATCH 27/84] fix(bin): treat Pi's dollar-first cost footer as
 furniture (#5683)

* fix(bin): treat Pi's dollar-first cost footer as furniture

An idle Pi status row opening with $0.000 was read as a dead-shell prompt, so exit and relaunch refused on an empty composer.

* test: wait for the draining holder to exec sleep before reading its identity

The procevent drain fixture read fm_pid_identity immediately after
backgrounding setsid sleep, racing the child's exec chain. Mid-exec the
cmdline can read empty, failing the fixture on a loaded CI runner.

Subject: [PATCH 28/84] fix(bin): refuse merges with unreported required checks
 (#5534)

* fix(bin): refuse a merge when a required check never reported

fm-pr-merge.sh built its GitHub refusals only from checks present in
statusCheckRollup, so a required check that never ran was simply absent and
the merge proceeded on the subset that reported, contradicting its own
"every required check green" claim.

The GitHub verify now reads the base branch's required contexts from the
forge itself - the classic branch protection summary on
GET repos/{o}/{r}/branches/{b} and the active ruleset rules on
GET repos/{o}/{r}/rules/branches/{b} - and refuses when a required context
has no entry in the same rollup, at the same head, that the merge is bound
to. Absence reads as unknown, never green. The required-set read joins the
existing refusal list, so a draft, a red check, and an unreported required
check are all reported together.

Could not read vs nothing required: both endpoints need only repository
read access. The admin-only GET .../branches/{b}/protection endpoint is
deliberately not used: it answers a non-admin token with the same 404 an
unprotected branch gets (observed live on kunchenguid/firstmate main with
this token), which would read a missing permission as "nothing required".
Any failed or malformed read of either source (auth, missing fine-grained
permission, rate limit, network, 404, unexpected shape) refuses the merge
with a line naming the unreadable source. The one exception is GitHub's
plan-gated 403 on the rules endpoint ("Upgrade to GitHub Pro or make this
repository public"), which already means "this repository has no branch
rules" for the merge-queue reader; that check moves into one shared helper
and the classic summary still decides for such a repository.

Attended waiver: --allow-missing <check-name> is the twin of --allow-red and
follows the same design and recording path: once, separate name argument,
waives only that exact unreported required check, still requires every
other required check reported and every check green, never waives an
unreadable required set, refused while the away-posture record exists, and
refused on GitLab. Merge-state BLOCKED policy is unchanged.

How this differs from the withdrawn #5353 (read from its diff):
- #5353 read the admin-only branches/{b}/protection endpoint and treated
  its 404 as "no required checks", so for any non-admin token the required
  set silently read as empty; this change reads the read-access branch
  summary and treats every failure as unreadable.
- #5353 ignored rulesets; this change also reads required_status_checks
  rules from the effective branch rules.
- #5353 made separate per-head REST reads of statuses and check-runs capped
  at per_page=100 with no pagination; this change checks presence in the
  same statusCheckRollup view the red-check gate already reads at the
  verified head.
- #5353 stopped at the first unreadable read; this change reports it as one
  refusal among all the others.
- #5353 also claimed #5345 (lock stealing) and changed 39 files, most
  unrelated; this change is #5344 only.

Live proof, read-only (a gh wrapper refused every merge and mutating call):
- cli/cli#14474 (trunk requires 3 classic build contexts, none ran):
  refused, naming build (macos-latest), build (ubuntu-latest),
  build (windows-latest); with --allow-missing "build (macos-latest)" it
  still refused, naming the other two.
- cli/cli#13665 (ran build (ubuntu-24.04-firewall) instead): refused,
  naming build (ubuntu-latest).
- hashicorp/terraform#39262 (ruleset-required checks absent): refused,
  naming Code Consistency Checks, End-to-end Tests, Race Tests, Unit Tests.
- cli/cli#14485 (all required reported and green): verified; the wrapper
  blocked the merge call and the pull request read back open.

Fixes #5344

* fix(review): Preserve required-check producers and aggregate independent read failures

* fix(document): Clarify required-check verification and waiver documentation

* fix(bin): match an app-bound required commit status by name

The producer-identity check resolved an app-bound required context only
against check runs, so a required context that the required app reports as
a commit status could never match and always read as "has not reported".
A commit status carries no app id to compare, so an app-bound requirement
that arrives as a status now matches by name, as before producer binding;
check runs keep requiring the configured producer app.

Live, read-only: hashicorp/terraform#39262 requires license/cla from
integration 865473, reported green as a commit status by the CLA app. The
previous head refused it as unreported; this head no longer does, while
still naming the four required check runs that never ran there.

Refs #5344

* fix(document): Clarify accepted commit-status producer verification limitation

 A PR ready for merge keeps the merge authority from `AGENTS.md` section 7, and a needs-decision finding keeps the `ask-user-authority` policy; anything requiring the captain still waits for the captain's explicit word.
 While the away-posture record exists, any pull request green at its live head may merge under away authority; which one the captain's words meant is the away session's reading, and a merge the words do not call for holds for the return.
 Away authority never releases a captain hold, and it expires when the away record is archived.

+`--allow-red` and `--allow-missing` remain attended-only and are refused while the record exists.
 A merge under away authority must be synchronous; `fm-pr-merge.sh` refuses auto-merge and any GitHub queue state that cannot prove an immediate merge while the record exists.
 The same gates bind whichever actor performs the action: on Pi the parked main's standing authority relocates to the supervision branch, which meets exactly these rules, and the spend cap recorded at entry is enforced by `fm-spawn.sh` for both actors while the record exists.
 The captain's away words are their explicit instruction given before leaving, recorded verbatim and acted on by the away session's judgment at the moment an event makes them relevant; the words cover nothing they do not say, are never applied by analogy, and die at archive.

 Destructive, irreversible, and security-sensitive merges still escalate.
 Without a current explicit captain instruction that states the concrete merge, the green default stands, and standing `yolo` cannot authorize a red merge; section 1 owns when such an instruction overrides a Firstmate-written standing rule within its exact scope.

 The record is the captain's away words, recorded verbatim: the explicit instruction the captain gave before leaving, and the whole mandate.
 No script parses them; you read them at the tail of every wake, decide by your own judgment whether the event in front of you is the moment they name, and act on them only through the guarded scripts under MAIN's standing authority - never more than MAIN could do attended - which enforce what a script can check without reading words:
 - `bin/fm-pr-merge.sh`: a merge the words call for proceeds when the pull request is green at its live head, synchronously, under the record lock; which pull request the words meant is your reading, and any green merge is mechanically permitted while the record exists.
-  A red pull request is never merged while away, whatever the words say, and `--allow-red` is refused under the record: a merge the words want past a red check holds for the return.
+  A red pull request, or one with a required check that has not reported, is never merged while away, whatever the words say, and `--allow-red` and `--allow-missing` are refused under the record: a merge the words want past a red or unreported check holds for the return.
 - `bin/fm-spawn.sh`: work the words explicitly call for is dispatched within the record's spend cap, from a queued backlog item - one already queued, or one you file yourself for exactly that step under the `backlog` lease, writing its brief intent from the captain's words and a backlog note citing them; filing the item the captain asked for is not inventing work, and anything the words do not call for is.
 - `bin/fm-send.sh` and `bin/fm-control.sh`: a run the words say to abort or a worker the words say to steer is steered, as in any posture.
 - `bin/fm-send.sh --resolve-key`: a decision the words pre-answer is answered with the captain's own answer, and every other decision only as the ask-user-authority policy at the end of this prompt lets firstmate decide; a finding it says to escalate is reported with verdict captain and left for the return.

+A required check that never reported is absent from the checks list rather than red; [`bin/fm-pr-merge.sh`](../bin/fm-pr-merge.sh)'s header owns required-context sources, producer identity, partial-read refusals, and attended check waivers.
 A check run is green when its current run is green, because GitHub leaves a cancelled run in the rollup beside the passing re-run it triggered when the base branch advanced; `bin/fm-pr-merge.sh`'s `github_checks_not_green` owns the rule, which uses `startedAt` to clear only an older completed check run that a passing run with the same name provably replaced, while unfinished check runs and non-green status contexts stay red.
 `--auto`, `--admin`, and branch-deletion flags are refused unless `--attended-override` is passed for an explicit captain instruction; that override never skips the live green check, the away-record read, or a captain hold.
-An attended `--allow-red <check-name>` may appear once, waives only GitHub checks with that exact name, and is refused while the away-posture record exists.
 Because away merge authority is read from that record and then acted on by the forge, the authority read and synchronous forge command share the record's cross-subsystem lock, closing the common live-owner TOCTOU.
 A lock that cannot be taken refuses the merge.
 While the record exists, GitHub auto-merge and any base whose rules cannot prove the absence of a merge queue are refused before submission, and GitLab auto-merge flags or scheduled state are refused while an immediate merge is forced with a final `--auto-merge=false`; a branch-rules read that fails only because the repository's plan does not expose branch rules at all (GitHub's plan-upgrade 403) proves the absence of a merge queue on its own and does not refuse, while every other failure to read that state still does.

Subject: [PATCH 29/84] fix: keep persistent secondmates out of landed-work
 cleanup (#5696)

* fix(bin): never offer a persistent secondmate for teardown

The return brief's "Landed, cleanup due" scan listed every state/*.meta
record carrying a pr= and a merge-notified marker without regard to kind, so
a secondmate record holding a relayed child's merged PR put the mate itself
up for "bin/fm-teardown.sh <mate>" cleanup. A secondmate is a persistent
worker, never landed work.

- bin/fm-afk-return.sh: skip kind=secondmate in the landed-cleanup scan.
- bin/fm-pr-check.sh: refuse to record pr= or arm a merge watch on a
  kind=secondmate record before any side effect; a PR reported on its routed
  status channel belongs to a task in the mate's own home, which arms its
  own watch.
- bin/fm-watch.sh: a merged result from a poll already armed on a secondmate
  retires the poll silently - no merge outcome, marker, or wake.

* no-mistakes(document): Document secondmate merge-watch and return-brief exclusions

* no-mistakes(ci): CI failed in an unchanged watcher-shutdown test whose three-second wait was sensitive to runner load. Increased the wait for both state- and home-deletion cases without changing watcher behavior. The full fm-watch-arm suite passed locally; syntax and diff checks passed

 Both relaunch only the recovery-grade `dead` and `missing` verdicts through the ordinary guarded `fm-spawn.sh --secondmate` path, a remote route is probed read-only across its host-local boundary and is never replaced by a local endpoint, and the per-mate liveness lock keeps a concurrent sweep and tick from killing or re-probing an endpoint the other is mid-relaunch on.
 Each automatic relaunch surfaces as exactly one `check` wake plus a durable line in `state/.secondmate-relaunch-<id>`, and a mate that exceeds `FM_SECONDMATE_LIVENESS_MAX_ATTEMPTS` ledgered attempts inside `FM_SECONDMATE_LIVENESS_WINDOW_SECS` is parked behind a bound marker and escalated once until a live probe rearms it with a full attempt budget.
 `tests/fm-wake-queue.test.sh` pins the no-progress notification, drain-progress reset, declared-pause exclusion, active-turn deferral, proven-idle child-first ring, busy and unknown parent-alarm paths, genuine stall after a ring, idempotence, quiet-queue, and byte-for-byte foreign-row preservation guarantees.
-When a canonical validated PR poll returns exactly `merged`, the watcher routes it through the shared merge-outcome emitter before retiring the poll.
+When a canonical validated task PR poll returns exactly `merged`, the watcher routes it through the shared merge-outcome emitter before retiring the poll.
+A legacy poll armed on a persistent `kind=secondmate` record is residue from a child's relayed PR: the watcher retires it without a merge outcome, notification marker, or wake, leaving the mate's lifecycle intact; `bin/fm-pr-check.sh` refuses new polls on such records.
 [`bin/fm-merge-outcome-lib.sh`](../bin/fm-merge-outcome-lib.sh)'s header owns role routing, PR-specific wake identity, marker-locked normal deduplication, and the at-least-once ordering that prefers a rare duplicate over silence.
 After successful outcome publication, the watcher immediately delivers the emitter's local actionable poll row and publishes a private retirement receipt bound to the poll's registration, bytes, file identities, metadata, provider, URL, and task ID.
 The retirement receipt makes poll cleanup safely retryable across restarts: fixed-path recovery revalidates the same evidence, removes the runnable check first, removes its registration and data sidecars, removes the receipt last, and preserves task metadata including `pr=` and `pr_head=`.

 The captain's away words are the whole mandate: the record owner's header is the single owner of the record schema, the words are recorded verbatim, and by the captain's mandate no parser, tokenizer, classifier, or grammar reads them anywhere.
 The supervision session reads the words at the tail of every wake and acts on them by its own judgment at the moment an event makes them relevant, only through the guarded scripts under standing authority, never by analogy, holding for the return on doubt; `bin/fm-branch-prompt.sh` "Postures" owns those execution rules.
 What stays mechanical is exactly what a script can check without reading words: a merge green at its live head under the record lock, synchronous merges only, the spend cap, and the never-set; destructive, irreversible, and security-sensitive actions are never pre-authorizable whatever the words say.
-The record's presence is the posture on every harness, `bin/fm-afk-launch.sh` owns entry and exit, and `bin/fm-afk-return.sh` archives the record and owns the return brief's ordered sections, including landed live task records that still owe cleanup, rendered from durable state.
+The record's presence is the posture on every harness, `bin/fm-afk-launch.sh` owns entry and exit, and `bin/fm-afk-return.sh` archives the record and owns the return brief's ordered sections, including landed live task records that still owe cleanup, rendered from durable state; persistent secondmates are excluded from that cleanup section even if an older record carries a child's merged PR.
 While the record exists neither supervisor rechecks an item held for the captain, and a declared external wait names when it clears with `until` for a condition-aware recheck in both postures that occurs at the declared time or the hours-long `FM_PAUSE_RESURFACE_SECS` bound, whichever comes first.
 On Pi and pi-signed the away daemon is no longer launched: the ordinary supervision session continues under the record with main parked, so the supervision branch takes every actionable wake, captain outcomes accumulate for the return brief, and main's standing authority relocates to the branch through the guarded scripts, each keeping its own gate ([`pi-supervision-branch.md`](pi-supervision-branch.md#postures)); a wake the branch cannot take and a watcher failure still reach main.
 On an opted-in non-Pi home, the [supervision host](supervision-host.md) runs the away session instead of the daemon.

Subject: [PATCH 30/84] fix: reject invalid X reply and follow-up arguments
 before posting (#5702)

* fix(bin): refuse unknown dash-leading args in public-posting fm-x scripts

fm-x-reply.sh collected any unrecognized argument into the positional
pool and took the first one as the reply text, so an invocation like
"fm-x-reply.sh <id> --followup --final <text>" posted the literal
string "--final" to X and silently dropped the real text.

Make argument parsing strict in every script that can post publicly:
an unknown dash-leading argument, a dash-leading request_id/task id, a
dash-leading option value, or a surplus positional now exits 2 with a
usage error before any config load, outbox write, or network call. Reply
text starting with '-' is still accepted via --text-file or stdin, and
--help is honored wherever it appears instead of becoming text (a --help
forwarded through fm-x-followup.sh would have counted as a posted
follow-up and mutated the link).

fm-x-link.sh and the fm-public-followup scripts already refuse unknown
arguments; fm-x-poll.sh takes none.

* no-mistakes(review): Refuse surplus follow-up text sources; drop post-ID help branches

* no-mistakes(document): Clarify reply and follow-up argument usage

* no-mistakes(review): Refuse dash-leading --text-file operands in fm-x-reply

* no-mistakes(document): Correct follow-up argument parsing comment

* no-mistakes(document): Document dismiss argument rejection in script header

Subject: [PATCH 31/84] fix: pause broken supervision-host sessions between
 engine probes (#5701)

* feat(bin): latch the supervision host after repeated engine errors

Rung 3c-1 of the PR 5631 re-cut: the host copies the Pi branch's
broken-session policy. Two consecutive engine errors latch the session;
every away wake then reaches main with one supervision-host line for a
five-minute cooldown, after which one wake probes the engine, and each
failed probe doubles the cooldown up to one hour. A reported turn without
an engine error clears it. The latch is kept per main session, engine, and
model in state/.supervision-host-health, and the engine conversation now
uses the same main-session key, which includes the lock holder's process
identity so a recycled pid never shares either.

Lifted from the validated 5631 tree and adapted to main's away-only host:
the attended recovery line and attended cooldown pass-through are left for
the attended core, so a recovery is only logged.

* no-mistakes(document): Consolidate supervision-host latch documentation

 A turn that fails also starts the next wake on a fresh engine conversation.
 When the captain returned during a failed turn that recorded outcomes, the handback carries those outcomes too, for main to relay.
 
+### The broken-session latch
+
+The host copies the Pi branch's broken-session policy ([pi-supervision-branch.md](pi-supervision-branch.md#broken-branch-latch-and-recovery)), with an engine error in place of a provider error: a turn that exited nonzero, hit its bound, or ended without a complete successful result.
+Two consecutive engine errors latch the session: every away wake reaches main with a `supervision-host:` line for a five-minute cooldown, after which one wake probes the engine, and each probe that ends in another engine error doubles the cooldown up to one hour.
+A turn that records a report without an engine error clears the latch; a turn with a complete engine result but no report neither counts toward it nor clears it, while an engine error counts even if no report was recorded.
+The first trip adds one `supervision-host:` line to the failing turn's handback, and a recovery is only logged.
+The latch belongs to one main session, engine, and model, so a new main session or another engine or model starts clean.
+An attended close is untouched, because attended closes already reach main.
+
 ### Lost ownership
 
 When the host loses session-lock ownership or its auto-arm generation, it stands down silently and leaves continuity to whoever owns it now.

Subject: [PATCH 32/84] fix(bin): absorb routine secondmate working and paused
 status appends (#5535)

* fix(bin): absorb routine second-mate progress while surfacing routed replies

Fixes #2959

A kind=secondmate task's status signal was never absorbable, so a healthy
mate's routine working: and paused: appends woke the primary every time.
signal_crew_provably_working now reads the mate's lines new since the
watcher's classified position: a decision, blocker, terminal outcome, note:,
correlation-marked line, or unknown verb still surfaces regardless of busy
evidence, while unmarked working:, paused:, and resolved: fall through to the
same provably-working absorb an ordinary crewmate gets.

* no-mistakes(review): narrow secondmate routine absorb to working and paused

 That bound is load-bearing rather than cosmetic: churn and staleness read the same pane, so a pane that renders continuously - a clock, a spinner, a shell heartbeat, or a harness that leaves a background renderer alive after its agent yields - never reaches the staleness backbone's two-identical-hashes test either, and an unbounded churn absorb would leave a genuinely stopped worker behind such a renderer with no path left to surface it.
 If two metadata records derive the same per-window marker key, including two records that name the same endpoint, that marker is not attributable churn evidence for either task, so the bare turn-ended wake surfaces without changing or migrating existing marker state.
-A `kind=secondmate` task's status signal is the parent-directed reply stream and is never absorbed as provably working; its bare turn-ended signal is absorbed only by the ordinary authoritative working proof because an active secondmate does not enter the staleness backbone that would resurface deferred pane-churn evidence.
+A `kind=secondmate` task's status stream doubles as its parent-directed reply channel, so its lines new since the last classification are read before busy evidence counts: a decision, blocker, terminal outcome, `note:`, correlation-marked line, or unknown verb always surfaces, while unmarked routine `working:` and `paused:` progress is absorbed only by the same provably-working proof an ordinary crewmate gets.
+Its bare turn-ended signal is absorbed only by the ordinary authoritative working proof because an active secondmate does not enter the staleness backbone that would resurface deferred pane-churn evidence.
 A crew that declares `paused:` for a known external wait, or carries a verified `captain-held` transfer, is separately absorbed while idle and re-surfaced only on the longer pause cadence, rather than being treated as a possible wedge, except that a captain-held transfer is not rechecked while the away-posture record exists.
 For an ordinary crew that has stopped, the normal-mode watcher first surfaces one stale wake, then applies that same cadence to an unchanged `paused:` or durable `captain-held` endpoint while attended; the pause classification itself is recovered only when the backend confidently reports its agent dead.
 Live or inconclusive liveness remains fail-open at that initial surface, so a worker genuinely waiting on a decision is never silenced.

Subject: [PATCH 34/84] fix(bin): bind inactive-outcome receipt identity to
 structured fields only (#5520)

* fix(bin): drop status prose from the inactive-outcome dedupe identity

The inactive-outcome receipt fingerprint included the child's sanitized
last status line, so a persistent child appending routine prose after one
terminal outcome minted a fresh parent event per sentence. Bind the
identity to incarnation, task id, terminal state, and PR only, keeping
the last line in the record as status_head evidence.

Fixes #2960

prompt and main's reply, only on a home with config/supervision-host, from
a genuine primary checkout, for the lock-owning session. The mirror lands
inert: writers record and nothing reads it yet; attended supervision on the
host is the later step that consumes the feed.

Codex, Grok, OpenCode, and omp have no writer here.

+#!/usr/bin/env bash
+# fm-host-mirror.sh - the supervision host's dialog mirror: what the captain and
+# MAIN said in the captain's conversation, recorded so the host's headless
+# engine session can be given it at the head of an attended wake
+# (docs/supervision-host.md "The dialog mirror"). The Pi branch mirrors the
+# same dialog in process (docs/pi-supervision-branch.md "How the branch knows
+# what the captain said"); this is its twin for a host that is not Pi, and the
+# one owner of the mirror file, its cursor, its lock, and the feed. Today the
+# writers record and nothing calls the feed yet: the host's attended posture
+# is the later step that reads it.
+#
+# WRITERS. Code-owned turn surfaces append here, never the model: Claude
+# through its prompt-submit and Stop hooks, and Cursor through its
+# beforeSubmitPrompt and afterAgentResponse hooks. Codex, Grok, OpenCode, and
+# omp have no writer (docs/supervision-host.md "The dialog mirror"). A writer
+# appends captain text (the submitted prompt) and MAIN text (the turn's final
+# assistant message), never tool traffic, as said, with only the whitespace at
+# the very end of the message trimmed. A prompt the shared operational-input
+# protocol classifies
+# (bin/fm-operational-input.sh: watcher wakes, guard follow-ups, launch briefs)
+# is fleet machinery, not dialog, and is dropped, and so is a prompt that opens
+# with the wrapper a harness puts around a turn it started itself: Claude
+# submits its Stop-hook rewake inside <task-notification>, with no other field
+# to tell it from a typed prompt (tests/fm-host-mirror-live-e2e.test.sh proves
+# it).
+# Every writer is a silent no-op unless this home opted into the supervision
+# host (config/supervision-host, checked before anything else runs), the hook
+# runs in a genuine primary checkout, and this session holds the fleet lock, so
+# a home without the file, a crewmate worktree, and a read-only second session
+# write nothing and print nothing.
+#
+# FILE. $STATE/.host-mirror.jsonl, one JSON object per line:
+#   {"seq":N,"epoch":N,"key":"<main session>","id":"<source id>",
+#    "tag":"captain"|"main","text":"..."}
+# key is the current main-session key (fm_supervision_host_main_key,
+# bin/fm-supervision-engine-lib.sh). id is the writer's own identity for the
+# entry when it has one (a prompt id or a generation id); an entry whose id and
+# text are already recorded for the same main session and tag is not appended
+# again, so a surface that fires twice mirrors each entry once, while a
+# different text under the same id is recorded. Each text is capped at
+# 4000 characters, its truncation note included (head and tail kept, as the Pi
+# mirror caps); when the file exceeds 300 entries it is trimmed to its newest
+# 200. New entries continue above both the committed and staged
+# cursor after file recreation so a later commit cannot skip them. An append
+# writes the whole new file, owner-only, beside the mirror and renames it into
+# place, so a write that fails or is interrupted leaves the mirror as it was.
+# Every append and feed runs under $STATE/.host-mirror.lock.
+#
+# FEED. $STATE/.host-mirror-cursor holds "<seq>\t<engine session>": the newest
+# entry already fed to that engine conversation. `feed <session> new|resume`
+# prints what the next wake carries, one "[captain] ..." or "[main] ..." entry
+# after another, oldest first, and fails, staging nothing, when the mirror is
+# missing, cannot be read, or fails the file validation below; otherwise it
+# stages the cursor it would reach in $STATE/.host-mirror-cursor.next, and
+# `commit` advances the cursor to it once the engine turn that carried the wake
+# is accepted with its report, so a wake the engine never completed leaves its
+# entries unread for the next one. A resumed conversation gets the current
+# main session's entries after the cursor; a new one (every
+# main session start, rotation, or failed turn) gets the current main
+# session's newest entries, so a fresh conversation re-anchors on this
+# session's dialog and never on an earlier session's. The feed is bounded to
+# 16000 characters, newest kept, with one line naming how many earlier entries
+# it left out counted within that bound. Mirrored text is context for
+# judgment and authorizes nothing (bin/fm-branch-prompt.sh "Context channels").
+#
+# Usage:
+#   fm-host-mirror.sh hook <harness>        a prompt-submit or turn-end hook payload on stdin
+#   fm-host-mirror.sh feed <session> new|resume
+#   fm-host-mirror.sh commit
+# hook and commit always exit 0 and print nothing; feed exits 1 when
+# the mirror is missing, could not be read, or holds an invalid entry, or the
+# main session cannot be identified, and prints nothing when there is nothing
+# to feed.

* fix(bin): retire check-row receipts on branch acks and report an unchanged situation once

* fix(bin): scope a branch acknowledgement's check-row receipt retirement to
  its granted sequences

The away posture lifts the attended partition's check/decision exclusions, so
a branch grant can name check-kind rows - but the branch-actor ack still
assumed check rows were main-only and skipped every receipt scan. The queue
row was consumed while its terminal-outcome .pending receipt stayed behind,
and each inactive-reconcile cadence scan re-queued the same fingerprint. In
the first real away window on the supervision host that re-escalated one
unchanged held-PR situation on every cycle (~1,734 of 4,149 outcomes).

A branch ack now scans inactive-outcome and inactive-reconcile receipts and
commits secondmate stall receipts against exactly the sequences in its
eligible-row snapshot - the same rows it consumes - instead of none. Attended
grants still name no check row, so the scans find nothing.

* fix(bin): store a repeated captain verdict as routine while the task's
  durable situation is provably unchanged

fm-branch-outcome.sh append computes a mechanical situation key per captain
row - metadata bytes, captured status-log endpoint and identity, live
crew-state verb, worktree head - and anchors it in
state/.<task>.branch-captain-key. A later captain verdict whose recomputed key
matches is stored as routine with "unchanged since seq <N>:" prefixed to its
summary, so one situation escalates once until something provably changes. A
task with no readable status ledger is never demoted, an unreadable record
fails toward reporting, and teardown removes the sidecar with the task's
other branch records. The append-only store schema is unchanged.

This covers both hosts: the Pi supervision branch and the supervision host
both funnel reports through append.

* docs: check rows are main-owned only while attended; the away posture grants
  them to the branch, whose ack retires their receipts exactly

* test: the away-flood reproduction as a regression test (branch ack retires
  the receipt and later scans stay quiet), store-level dedupe coverage, and a
  branch-ack secondmate stall receipt case

* fix(bin): restore the secondmate child devin-config cleanup path

The branch-captain-key sidecar addition mistyped the sibling entry as
.$child_id.devin-config.json, so a forced secondmate teardown would have
stopped removing each child's real <id>.devin-config.json. Restore the
original path and add a behavioral test that stops the child sweep mid-loop
on a refused close, proving the cleaned child's devin config and captain
anchor are both removed while the unconsumed child's records are retained.

* no-mistakes(review): Key captain dedupe on the covered wake rows' fingerprint

* no-mistakes(review): Drop captain-key demotion; prove one escalation on both surfaces

* no-mistakes(review): Drop unrelated teardown test; cite both receipt test files

* no-mistakes(document): Docs already match branch-ack check-receipt retirement

+While attended, a check-kind row is main-owned, including a heartbeat review.
 So it is never part of a branch claim and never defers one.
 Main is woken for it on that check's own triggering close.
+Under the away-posture record the exclusion lifts and a check row is offered to and claimed by the branch like every other actionable row.
 
 `fm-wake-drain.sh` never reclassifies a row itself.
 It filters the queue to the current actor's opaque claim before same-key deduplication, then presents and acknowledges only that actor-local view.
 A missing or empty branch snapshot is refused loudly rather than read as "nothing eligible", because reaching the drain without the non-empty handoff promised by the extension is a wiring bug.
-Because branch claims contain no check-kind rows, a branch acknowledgement skips check-specific receipt scans.
+A branch acknowledgement retires the check-row receipts - inactive-outcome, inactive-reconcile notice, and secondmate stall - of exactly the granted sequences it consumes, so a branch-consumed check is never re-queued by its producer.

Subject: [PATCH 37/84] fix(bin): deliver Claude-bound operational input as a
 record-backed doorbell (#5664)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(calm): deliver Claude-bound operational input as a record-backed doorbell

Claude Code 2.1.280 removes U+2063 from every submitted prompt, so a typed
operational envelope reaches a Claude Code primary as plain text. The away
daemon now writes the envelope to a record under state/operational-inbox and
types only a plain doorbell naming it; the /afk return check and the Calm mod
recognize the doorbell only when that record holds a current envelope. Marker-
preserving harnesses keep the typed envelope. The live Calm guard accepts the
2.1.280 module-load log line, drives the doorbell, and asserts thinking stays
hidden.

* no-mistakes(review): Fix operational record retention at 7 days and document prune limit

* no-mistakes(document): Point Calm bounds at 2.1.280 evidence; fix afk-exit comment

* no-mistakes(lint): Pick newest Calm e2e transcript without parsing ls

* docs(calm): add a minimal turning-Calm-on step for Claude Code

* fix(spawn): deliver the Claude launch brief as a record-backed doorbell

Claude Code strips U+2063 from the launch-prompt argument too, so a
worker's launch brief arrived with its operational marker removed.
Publish the brief as a record in the receiving home's operational
inbox - a secondmate's own state, not the primary's - and pass only
the printable doorbell naming it, falling back to the typed envelope
when the record cannot be published so the brief body still delivers.

Unwrap doorbell-carried digests in the daemon digest tests that still
read the raw send log under the claude pin, and update the documented
bounds now that launch briefs hide like the other operational rows.

* test(spawn): cover a secondmate's launch-brief record landing in its own home

The record-backed doorbell resolves its state through the receiving
pane's home, so prove a claude secondmate launch publishes into the
seeded secondmate's operational inbox and never leaks a record into
the primary's.

* no-mistakes(review): Pass primary harness to daemon, tighten retention, refresh verdicts

* no-mistakes(review): Prune operational records by exact seven-day elapsed age

* no-mistakes(review): Batch record pruning so large inboxes still expire

* no-mistakes(review): Refuse Claude spawn when brief record cannot publish

* no-mistakes(review): Drop thinking probe from Claude Calm live test and docs

* no-mistakes(review): Record dated Claude Code 2.1.282 reproduction evidence

* no-mistakes(document): Clarify operational doorbell documentation and record expiry

* no-mistakes(document): Correct AFK escalation carrier guidance

* no-mistakes(review): Describe operational record retention as about seven days

* no-mistakes(document): Clarify Calm delivery and operational record retention

* no-mistakes(review): Remove out-of-scope Calm launch guide from Claude docs

* no-mistakes(document): Document Claude launch-brief delivery and refusal

* no-mistakes(document): Correct stale operational-input documentation

* no-mistakes(ci): Fixed the stale Claude trust test to verify that worker and secondmate launches deliver readable, record-backed briefs instead of expecting brief paths in their commands. Annotated the daemon’s output variable for ShellCheck without changing behavior. The affected tests, daemon tests, ShellCheck, and diff check pass locally

* no-mistakes(ci): parse rebased Claude launch after trailer hook prefix

* no-mistakes(review): Trust launch-brief record and restore thinking bound doc

* no-mistakes(review): Parse final Claude launch statement; drop Stop-hook docs

 Invoke the `/quiet` skill instead when the captain says `/quiet` or asks for quiet mode, or `state/.afk` already exists in quiet mode (`fm_afk_mode` in `bin/fm-wake-lib.sh`).
 Each skill owns its own daemon procedure, which is otherwise identical; these safety facts remain inline for both:
 
-- Every current daemon injection uses the `away-supervisor` kind from `bin/fm-operational-input.sh` after `FM_OPERATIONAL_PREFIX` (U+2063 INVISIBLE SEPARATOR followed by `FIRSTMATE_OP: `), while the `/afk` skill owns legacy bare-marker compatibility.
+- Every current daemon injection uses the `away-supervisor` kind from `bin/fm-operational-input.sh` after `FM_OPERATIONAL_PREFIX` (U+2063 INVISIBLE SEPARATOR followed by `FIRSTMATE_OP: `), except that a Claude Code primary, which strips U+2063, receives that owner's record-backed doorbell and it counts as marked only when `bin/fm-operational-input.sh open <path>` verifies its record; the `/afk` skill owns legacy bare-marker compatibility.
 - `state/.afk-contract` is the away posture, written in the same turn as `/afk` before any other work, because `/afk` is itself the go: no read-back gates entry or waits for a go; entry announces hold-for-return only, and the away session acts on those words by its own judgment through the guarded scripts under standing authority, holding for the return on doubt.
 - While `state/.afk` exists, the daemon owns supervision; do not arm a separate watcher.
   The daemon is never launched on Pi, where the ordinary supervision session continues under the record with main parked: the branch takes every safe actionable wake it can, and only a declined wake (including a broken branch or unsafe scan) or a watcher failure wakes main.

+Calm changes only presentation, not the user-role delivery, ordering, authority, persistence, or exports of the operational inputs it hides.
 The preference persists for the effective Firstmate home, and toggling it off restores ordinary rendering.
 [Calm's current behavior and supported limits](docs/calm.md) are separate from its [version-scoped maintainer evidence](docs/calm-mode-feasibility.md).
 Pi's `/supervision-model` command pins a cheaper model and a shallower reasoning effort for the supervision branch alone, from the eligible models and thinking levels Pi itself reports, and with no pin the branch normally follows your own conversation's model and effort; see the [configuration schema](docs/configuration.md#pi-supervision-branch-model-and-effort-configsupervision-branch-model-configsupervision-branch-effort).

+
+Claude Code 2.1.280 removes invisible characters, U+2063 included, from every submitted prompt, whether typed, pasted, or passed as the launch prompt.
+A typed operational envelope first shows `Removed 1 invisible character · review and press Enter to send`, and the next Enter stores it as plain `FIRSTMATE_OP: ...` text that no consumer can tell apart from a human message.
+No setting or environment variable turns the removal off.
+For the current delivery and presentation contracts, see [`fm-operational-input.sh`](../bin/fm-operational-input.sh) and [`calm.md`](calm.md#claude-code).
+
+2.1.280 also logs the module load as `hooks module firstmate-calm@<source> loaded` (`@skills-dir` for the project auto-load path), so the live guard matches either form.
+
+Observed on 2.1.280 with the flag on, beyond the live guard:

 On Claude Code the boat is painted in Claude Code's own theme colors rather than Pi's standard ANSI codes: every water cell takes the spinner blue of the active theme family (`#93a5ff` on a dark theme, `#5769f7` on a light one) and the whole boat, both sail halves, mast, and hull, takes the Claude orange of the stock spinner (`#d77757`).
 The family follows the `theme` setting by its prefix, `dark` or `light`, is re-read when the theme changes, and uses the light set as the both-readable fallback for `auto`, custom, missing, or unreadable values; the Pi extension keeps its standard ANSI blue and yellow.
 Tool rows, tool result blocks, and folded tool groups draw at zero height, so a turn that used tools takes the same space as one that did not.

+A user row whose text the canonical operational-input parser recognizes, a Firstmate session-start, watcher, turn-end guard, away-supervisor, launch-brief, or branch-outcome envelope, a from-firstmate routed message, or one of the narrow pre-protocol shapes kept for old transcripts, draws at zero height; other user rows, including near misses such as a quoted or ASCII-only marker, stay visible unless backed by an operational record as described below.
+Claude Code removes the U+2063 that starts those envelopes from every submitted prompt, so Firstmate delivers its away-mode escalations to a Claude Code primary as the record-backed doorbell `bin/fm-operational-input.sh` owns: a plain line naming a record under the home's `state/operational-inbox` that holds the envelope.
+Calm reads that record through the mod's file API and hides the doorbell row only when the record holds a current envelope, so a doorbell-shaped line naming no such record stays visible; a verbatim copy of a live doorbell line, pasted back while its record still exists, is treated as Firstmate's and hides.
+Record verdicts are cached until a drawing invalidation (including a `/calm` toggle), which rechecks pruned records on redraw.
 Assistant text follows the shared per-block preservation rule above, including when `claude --continue` restores the transcript.
 Toggling Calm redraws every hooked row already on screen, so rows drawn before the toggle hide or restore retroactively, and the preference is read before the first row draws.
 Nothing is rewritten: hidden rows remain in the message, model context, session storage, and exports, and the mod never touches tool execution, prompts, or the stored transcript.

+- Firstmate's typed producers bound for a Claude Code pane - the away-mode daemon's escalations and a worker's launch brief - ride the record-backed doorbell, so they hide like any operational row; only an envelope that reaches Claude Code some other way as bare typed or launch-prompt text arrives without its U+2063 and stays visible.
+- Every record write prunes operational-inbox records once they reach about seven days of elapsed age (the boundary is approximate); age alone does not remove a record without a later write.
+  Once its record is gone, a doorbell is no longer recognized: it draws as a visible user row after Calm rechecks it (for example on `/calm` toggle or `claude --continue`) and `/ahoy` treats it as a captain boundary.
 - On the main-screen layout (not the fullscreen alternate screen), a toggle redraws the live screen by clearing and reprinting it, and the terminal's own scrollback keeps the earlier rendering above it; the fullscreen layout has no such stale copy.
 - The sailboat is painted through Claude Code's Raster element, whose colors are RGB quantized to 256-color escapes rather than the standard 16-color ANSI codes Pi's widget emits.
 - The detailed transcript view (`ctrl+o`) keeps its per-message timestamp and model headers where hidden assistant rows sat, because those headers are not a hookable drawing.

 Launch mechanics, including the verified command templates, live in [`bin/fm-spawn.sh`](../bin/fm-spawn.sh).
+A Claude worker's launch brief is published as an operational record in the receiving home's state and delivered as a printable doorbell; if publication fails, the spawn reports the failure and launches nothing rather than sending a marker that Claude Code would strip.

 U+2063 survives Herdr terminal input as text, unlike the legacy ASCII control separator that could erase the visible routing label.

Subject: [PATCH 39/84] fix(bin): republish parent metadata after a remote
 secondmate relaunch (#5583)

A host-local relaunch rewrote only the far endpoint, so this home kept the old harness, model, and effort, and appending those keys after pr= broke pull-request poll authentication.

 If the secondmate is already running and only inherited local material changed, prefer `bin/fm-config-push.sh` over respawning.
 To move a live LOCAL secondmate onto a newly pinned harness, model, or effort without a full recovery, set `config/secondmate-harness` and then relaunch it with `bin/fm-control.sh <id> relaunch`, which re-resolves that pin, stops the agent, and launches the replacement in the same home ([`docs/agent-control.md`](../../../docs/agent-control.md)).
 That plane refuses a remotely placed secondmate by name, because its agent runs on another host where none of the plane's postconditions can be read.

 A successful update restarts every live mate of both placements on its own, including one already on the target commit; the `/updatefirstmate` skill owns that pass, and `bin/fm-secondmate-restart.sh` owns its persist gate and failure vocabulary.

Subject: [PATCH 40/84] fix(bin): give slow watcher suites headroom under the
 changed-suite bound (#5516)

tests/fm-watch-triage.test.sh finishes in about 434s alone and about 698s
under CI load, so the 900s bound the changed-suite runner applies produced
a false timeout under ordinary concurrent validation. Raise the automatic
bound to 1500s, which keeps every measured script under it while staying
below the 30-minute normal CI tier so a genuinely hung script still fails
here with its output before the job cap cancels the lane.

Fixes #3869
Refs #3565

Subject: [PATCH 41/84] fix(bin): stop nested steal-lock recursion and
 mid-steal watcher TERM (#5728)

* Fix nested watcher lock reclaim

* no-mistakes(review): Elect a single steal-mutex reaper and bound arm TERM wait

* no-mistakes(review): Reclaim self-held steal mutex and unify autoarm steal reaping

* no-mistakes(review): Resume own interrupted steal reap from its tombstone

Subject: [PATCH 42/84] test: make supervision-host park-boundary tests
 deterministic (#5710)

* test: hold the back-to-back boundary close on the host's own clock

test_park_boundary_holds_under_back_to_back_closes assumed two engine
turns fit in the ~16s pre-refusal window and that the stub finished a
turn in 3s. Under load the stub's real drain, report, and
acknowledgement take ~13s, so the turn either died at its bound (which
hands the wake to main, no boundary line) or the second close landed
past the window and the fixture failed while the boundary held. 3
failures in 5 runs at a load average near 11.

Hold the first turn on a release file instead: once the engine is in
flight, a second close is appended mid-turn and the turn is released as
the refusal window opens (park bound minus turn bound and grace, read
off the host's own start record). The queued close can then only wait
for the boundary on any machine speed, which is what the test asserts:
the boundary line ends the output, the demo.status row stays queued for
main, and no second engine turn ever starts. A host too loaded to start
the turn at all hands the first close to the same boundary exit.

After: 12/12 at load ~15-42.

* no-mistakes(review): Print boundary test deadline as a decimal integer

* no-mistakes(review): Hold boundary test turn on a FIFO, require full sequence

* no-mistakes(review): Remove stray before/after supervision-host test copies

* test: hold the late close's render until the refusal window opens

The boundary recheck test's node shim slept a fixed 10s, which assumed
the first close was read before the host's refusal window opened. Under
load the close arrived after the refusal check, so the host correctly
refused it before the successor started and the render snapshot never
appeared. Block the wake-prompt render on a FIFO released at the
refusal-open instant read from the host's own start record, so the
pre-turn recheck must refuse on any machine speed.

* no-mistakes(review): Derive minimal park bounds and refresh supervision-host shard hint

* no-mistakes(review): Drive park-boundary tests from a seam-gated host test clock

Subject: [PATCH 43/84] fix: stage remote home clones before publication
 (#5733)

* fix(bin): stage remote home clones before publishing them

A remote home provision cloned the code root directly into the public
FM_HOME path while rollback() claimed rm -rf of that same path on any
failure. Bash defers trapped signals past a foreground child, but any
other cleanup or lifecycle path that removes the home directory races
the live clone's object copy, producing the CI flake "fatal: failed to
copy file to .../.git/objects/...: No such file or directory".

Clone into a private staging directory beside the home and publish with
an atomic rename once complete, so no cleanup can remove a directory a
live clone is still writing; a home that appears mid-provision now dies
cleanly instead of inheriting torn state. The regression coverage holds
a real clone mid-copy, removes the public path, and requires the
provision to finish and publish intact.

* no-mistakes(review): Prove home ownership by sentinel and hold only a live clone

* no-mistakes(review): Assert raced provision publishes a complete, intact clone

* no-mistakes(document): Document remote home staging and publication safety

* no-mistakes(lint): Fix ShellCheck warning in clone integrity assertion

* no-mistakes(document): Clarify remote home publication and rollback guarantees

 ### Failure and rollback
 
 A known provisioning failure rolls back the new route.
+A new remote home is published only after its checkout is complete, so removing the public path during cloning cannot interrupt the clone.
+If a competing home appears before publication, provisioning fails and leaves that home intact.
 SSH exit 255 preserves the route, because remote completion is unknown and must be reconciled on the same host.

Subject: [PATCH 44/84] fix: preserve Herdr status on Pi relaunch (#5161)

* fix(control): keep a relaunched Pi worker's herdr pane status authority alive

Defect: after `bin/fm-control.sh <id> relaunch` (observed live on a herdr
Pi crewmate whose pane read idle while it ran its validation pipeline),
the pane froze at whatever its previous agent had last reported.

Cause, measured on herdr 0.9.1 against a real Pi: a pane has one status
authority, and for Pi with its integration installed that authority is
the lifecycle hooks, so herdr also skips screen detection for the pane.
In the crew shape the registration outlives its agent process (upstream
issue #4115; docs/herdr-backend.md "Restart and liveness behavior"), and
herdr applies only reports carrying the session identity it bound. A
replacement started fresh in that pane reports a NEW session, so its
state reports are ignored and the pane stays frozen. Nothing from
outside repairs it: `pane report-agent-session` and `pane report-agent`
for `herdr:pi` are accepted (rc=0) without being applied unless the
reporter is the registered pane agent, and `pane release-agent` on the
stale record changes nothing.

Fix: a relaunch preserves the binding instead of fighting it. The launch
owner reads the session reference the endpoint's own runtime recorded
(`fm_backend_herdr_pane_agent_session_ref`) and passes it back as Pi's
own `--session <path-or-id>` (`relaunch_resume_args`;
`fm_control_relaunch_resume_flag` owns which adapters and which
registered-agent labels qualify). That is the same reference herdr
itself resumes Pi panes with after a server restart, and the resumed
session's reports land again, which the live check confirmed: the pane
returned to working while the replacement worked and idle when it
settled, on the same session identity.

Safety: relaunch-only (a fresh spawn binds nothing), herdr-only (the one
adapter that records a per-pane session), Pi-family only, and only when
the registration's own agent label matches - so no other adapter's
conversation can be handed to a Pi launch. An unreadable, missing, or
malformed reference degrades to exactly the fresh-session launch that
existed before. No lifecycle, liveness, isolation, or merge guard is
touched, and an empty result leaves every non-Pi launch byte-identical.
`resume` remains a refused verb; docs/agent-control.md and the
harness-adapters references are corrected where they claimed Pi had no
verified resume form at all.

* no-mistakes(document): docs: correct relaunch session-authority ownership and skill paths

* no-mistakes(document): docs: correct stale control-plane ownership claim

* no-mistakes(document): docs: drop unverified Herdr restart resume claim

* no-mistakes(test): Added offline Herdr Pi session-authority relaunch coverage

* no-mistakes(document): Document Herdr Pi relaunch session continuity

* no-mistakes(ci): The failing remote relaunch test tried to arm a PR poll for a secondmate, which `fm-pr-check.sh` correctly refuses. Removed that invalid test scenario; the remaining remote relaunch tests pass, and `git diff --check` is clean

+## Agent status authority and relaunch
+
+A pane has ONE status authority, and for Pi with the integration installed that authority is the lifecycle hooks - Herdr then skips screen detection for the pane, which is the `full_lifecycle_hook_authority` reason `herdr agent explain` prints for it.
+That authority is bound to a session identity, and in the crew shape the registration outliving its process ([above](#restart-and-liveness-behavior)) is that same binding: the record stays, the agent it named is gone.
+
+An agent started FRESH in such a pane reports a new session and Herdr ignores its reports, so the pane stays frozen at whatever the previous agent last reported - a crewmate running its pipeline reads `idle` until its task ends, and nothing from outside repairs it (measured 2026-09-21 on Herdr 0.9.1 against a real Pi; `pane report-agent-session` and `pane report-agent` for `herdr:pi` are accepted without being applied unless the reporter is the registered pane agent, and `pane release-agent` on the stale record changes nothing).
+A fresh spawn never meets this: it gets a new pane with nothing bound.
+
+So a **relaunch** preserves the binding instead of fighting it: before the Pi-family launch line is composed, `bin/fm-spawn.sh` reads the pane's recorded session reference through `fm_backend_herdr_pane_agent_session_ref` and passes it back as Pi's own `--session <path-or-id>` (`relaunch_resume_args`; `bin/fm-control-lib.sh`'s `fm_control_relaunch_resume_flag` owns which adapters and which registration labels qualify).
+The replacement therefore starts on the exact identity the authority is bound to, and its `working`/`idle`/`blocked` reports land again.
+The reference is the endpoint's own record, never a guess about which session is recent, and only a `pi` label may supply it: a registration belonging to another adapter is ignored, as is an unreadable, missing, or malformed one, in which case the relaunch is the ordinary fresh session it always was.
+A relaunch that changes harness AWAY from Pi is not repaired by this and keeps the pre-existing behavior; only the adapter the authority belongs to can resume its session.
+
+The session file may not exist any more: Pi creates it at exactly that path, so the identity survives either way.
+The read grants no send, close, or lifecycle authority of its own - it is a read of Herdr's record.
+The portable halves are pinned by `tests/fm-backend-herdr.test.sh` (the read, against a canned CLI) and `tests/fm-control.test.sh` (the per-adapter rule), and `tests/fm-control-herdr-smoke.test.sh` exercises the relaunch path against the real binary; the versioned live measurement, including the reproduction and the resume that lifts it, is [`verification/runtime-backends.md`](verification/runtime-backends.md) "Pane status authority across a relaunch".

 `tests/fm-crew-state.test.sh` pins the recovery classifier: a stale registration over a shell-only pane reports agent gone rather than alive or unreachable, and a stale `working` record never reports the pane working.
 A stale-registration pane is never a husk: create, reclaim, presentation recovery, and session cleanup keep refusing it, and only recovery reuses it.
 
+### Pane status authority across a relaunch
+
+Measured 2026-09-21 on Linux x86_64 against Herdr 0.9.1 (client protocol 22) and Pi 0.86.1, in an isolated `fm-lab-` session (`bin/fm-herdr-lab.sh`), after the same freeze was observed live on a relaunched Pi crewmate whose pane read `idle` while its validation pipeline ran.
+
+The stale registration above is not only a recovery-classification problem: it is the pane's status AUTHORITY, and it is bound to one agent session identity. Herdr applies a lifecycle/session report only when it matches what it bound, so an agent started FRESH in that pane - the shape `bin/fm-control.sh <id> relaunch` produced before this fix - reports a new session into a pane that ignores it. The pane then stays at whatever the previous agent last reported: working reads idle, indefinitely, because the registration outlives its process and nothing from outside repairs it.
+
+Reproduced with a real Pi under a nested shell, `/quit`, and a second fresh Pi in the same pane:
+
+```sh
+# nested shell, then a real pi (a prompt is what makes the extension report;
+# session_start alone did not register on this version)
+herdr pane send-text w1:p1 'zsh' --session "$LAB"; herdr pane send-keys w1:p1 Enter --session "$LAB"
+herdr pane send-text w1:p1 "$PI --tui-mode regular 'say ready'" --session "$LAB"; herdr pane send-keys w1:p1 Enter --session "$LAB"
+herdr agent get w1:p1 --session "$LAB" | jq -c '.result.agent | {agent_status, session: .agent_session.value}'
+herdr pane send-text w1:p1 '/quit' --session "$LAB"; herdr pane send-keys w1:p1 Enter --session "$LAB"
+# then start a SECOND fresh pi in the same pane and re-read
+```
+
+```text
+{"agent_status":"idle","session":"/home/u/.pi/agent/sessions/--wt--/2026-09-21T14-10-08-776Z_01a0c44d.jsonl"}
+# after /quit: the registration and its session are still there, process gone
+{"agent_status":"idle","session":"/home/u/.pi/agent/sessions/--wt--/2026-09-21T14-10-08-776Z_01a0c44d.jsonl"}

+{"agent_status":"idle","session":"/home/u/.pi/agent/sessions/--wt--/2026-09-21T14-10-08-776Z_01a0c44d.jsonl"}
+```
+
+Two repair paths were measured and do not work, so the reference is preserved rather than cleared:
+
+- `herdr pane report-agent-session` / `report-agent` from another process are accepted (rc=0) and never applied, for `--source herdr:pi`; the same source's reports are accepted when the reporting process is the registered pane agent (Pi's own extension) and when a custom source is used, which is how the smoke fixtures register one.
+- `herdr pane release-agent --source herdr:pi --agent pi` on that stale registration is accepted (rc=0) and changes nothing, matching its documented guard that it only ends authority when the agent process exits.
+
+Resuming the bound session instead makes the replacement's reports land, which is what `bin/fm-spawn.sh` now does for a relaunch:
+
+```text
+# C: quit the fresh second pi, then pi --session <the bound path> with a slow turn
+poll 8: {"agent_status":"working","session":".../2026-09-21T14-10-08-776Z_01a0c44d.jsonl"}
+```
+
+The read that supplies the reference is `bin/backends/herdr.sh`'s `fm_backend_herdr_pane_agent_session_ref`, the per-harness rule is `bin/fm-control-lib.sh`'s `fm_control_relaunch_resume_flag`, and the launch argument is composed by `relaunch_resume_args` in `bin/fm-spawn.sh`; `docs/herdr-backend.md` "Agent status authority and relaunch" owns the contract. Nothing here changes `resume` as a control verb, and only a relaunch asks for it.
+
 ### Away-mode transport
 
 The away daemon is no longer launched on Pi; the away posture there is the record `bin/fm-afk-contract.sh` owns.

Subject: [PATCH 45/84] Seed the relaunch-ordering PR poll fixture without
 fm-pr-check.sh (#5758)

Main has been red since fm-pr-check.sh began refusing to arm a merge poll
on a kind=secondmate record (#5696): the relaunch-ordering case in
tests/fm-remote-secondmate-relaunch.test.sh armed its fixture through that
entry point and could no longer be set up.

The ordering guarantee still matters: a secondmate record armed before the
refusal can legitimately carry a trailing pr=/pr_head= identity block until
the watcher retires it, and fm-remote-secondmate-relaunch.sh must still keep
that block last when republishing harness/model/effort. Seed the fixture the
way such a record was really written - pr= appended last to the meta, then
the poll artifacts published through the same
fm_pr_poll_prepare/fm_pr_poll_publish_prepared pair fm-pr-check.sh uses, a
pattern tests/fm-pr-check-security.test.sh already follows - and drop the
now-unused fake gh fixture. The #5696 refusal itself stays pinned by the
security suite's secondmate-record case.

Subject: [PATCH 46/84] feat: add attended supervision for Claude and Cursor
 hosts (#5748)

* feat: run attended supervision on the host for Claude and Cursor

On a home opted into config/supervision-host with a Claude or Cursor
primary, the supervision host now takes the attended wakes the Pi branch
would take: routine outcomes stay off main, and a captain outcome wakes
main once with a branch-outcome line and waits in the drain's new
BRANCH OUTCOMES section until main acknowledges it with mark-processed.

- The offer rule moves into branchOfferForWake, shared by the Pi watcher
  and the host through bin/fm-branch-dispatch.mjs offer.
- The host feeds the dialog mirror at the head of each attended wake and
  passes a close through unchanged when it is main-only, the engine or a
  tool is missing, the primary has no verified mirror, the main session
  cannot be identified, or the session is cooling down.
- The drain presents captain outcomes first, one line per task, never
  behind older routine outcomes, and collapses routine overflow into a
  count that is marked read.
- The return advances the store's read cursor through the away window
  once the brief has rendered, so the first drain does not replay it.
- The branch prompt's mirror wording is host-neutral, and the rule to
  report what main must act on as captain, once per unchanged situation,
  applies only to the attended posture on the host.

* docs: record the attended supervision host live check

* no-mistakes(review): Present pre-window unread outcomes and contiguous captain prefix

* no-mistakes(review): Return brief presents every row it marks read

* no-mistakes(review): Return brief lists every unread outcome in one list

* no-mistakes(review): Keep return list in store order and gate cursor failures

* no-mistakes(review): Make the drain the only branch-outcome presenter after return

* no-mistakes(review): Gate return on drain outcome failures; byte-count outcome budgets

* no-mistakes(review): Gate drain on projection failures; UTF-8-safe byte cuts

* no-mistakes(review): Fail drain without jq; hand unreadable prompt mirror to main

* no-mistakes(document): Correct supervision-host return and drain documentation

* no-mistakes(review): Recheck attended offer at turn start; honest failed-drain brief

* no-mistakes(document): Correct supervision-host posture and drain documentation

* no-mistakes(document): Documentation remains accurate for attended supervision

+#     (bin/fm-branch-dispatch.mjs offer) says the branch may take this close,
+#     so main-only classes (check triggers, decision-owned triggers, a scan
+#     that is unsafe or holds nothing for the branch) stay main's;
+#   - away (the record exists): every close goes to the engine.
+# Every turn that starts attended meets that rule again at its start, so a
+# close accepted away whose turn starts attended (the captain returned in
+# between) or an attended close whose task turned main-only while the
+# successor started reaches main exactly as the arm printed it.
+# A close the engine takes is handled in one order: it starts and verifies the
+# successor watcher cycle and confirms the handling handoff (the order
+# docs/watcher-continuity.md owns), computes the rows the branch may claim in
+# the turn's posture with the dispatch owner, publishes that grant
+# (bin/fm-wake-grant.sh), runs one bounded headless engine turn
+# (bin/fm-supervision-engine-lib.sh) with the generated branch prompt
+# (bin/fm-branch-prompt.sh), the dialog-mirror feed (bin/fm-host-mirror.sh)
+# at the head of an attended wake and the away tail instead when away,
+# releases the branch's leases and grant, and counts the wake handled only
+# when that turn exited cleanly, recorded a durable report
+# (bin/fm-branch-report.sh), and left none of its granted rows in the wake
+# queue. A handled wake with only routine outcomes never wakes
+# main, and neither does any handled wake while away: captain outcomes wait in
+# the outcome store for the return drain's BRANCH OUTCOMES section. A handled
+# attended wake that recorded a captain outcome exits with one "supervision-host: branch-outcome:"
+# line naming its store rows, without the close it handled; main drains, where
+# the BRANCH OUTCOMES section (bin/fm-wake-drain.sh) presents every
+# unprocessed captain outcome until main acknowledges it. Otherwise the host
+# parks on the successor.
 # Every other outcome exits with the close's own reason line plus one
 # "supervision-host:" line saying why main has this wake, after stopping the
 # successor cycle so main's next turn end starts from the same state as
-# without the host. Whenever the captain returned during an engine turn that
-# recorded outcomes, handled or not, the return brief was rendered before they
-# existed, so the host exits with the close, one "supervision-host:" line

+#     mark-processed target, the newest presented row, acknowledges exactly
+#     what was presented and always at least the oldest row. An unprocessed
+#     captain row is never adopted as processed, so a home that opts in

+## Captain outcomes
+
+A captain outcome the attended engine records while the captain remains attended wakes main once, through the owner's ordinary wake path, with one `supervision-host: branch-outcome:` line naming its store rows.
+Main drains, and `bin/fm-wake-drain.sh` presents it in its `BRANCH OUTCOMES` section with the exact `bin/fm-branch-outcome.sh mark-processed --through <seq>` acknowledgement.
+That presentation is what the Pi branch's visible entry is, so it advances the store's read cursor through the rows it presents.
+Every later drain, including the session-start digest, presents unprocessed captain outcomes again until main acknowledges them, so an ignored outcome costs no extra turn and is never lost.
+The drain's header owns the section's bounds; these rules keep it bounded and in order:
+
+- Captain outcomes come first and never wait behind routine ones.
+- Repeated captain outcomes for one task collapse to that task's newest, naming how many it carries, and one acknowledgement covers them.
+- The byte cap shows only the oldest contiguous run of captain outcomes, so the printed acknowledgement covers exactly the rows shown, and it counts the newer ones it holds back, which follow once the run is acknowledged.
+- Routine outcomes never open a main turn: the next drain lists the newest of them once, for awareness and with nothing to acknowledge, and collapses the rest into a count, while silent fleet reviews never appear.
+
+The section runs only for main on an opted-in home whose primary is not Pi, and never while the away record exists.
+The drain is the only presenter of these outcomes and the only owner of their read cursor, the away window's included: the return brief counts the window's outcomes and points at the section instead of listing them.
+A long away window no longer requires a drain per outcome: each task's captain outcomes collapse to one line, subject to the captain byte cap, and routine ones past the section's limit collapse into a count; after main acknowledges all captain outcomes no later drain shows anything from the window again.
+A drain that cannot read or project the store (jq missing included), print the section, or advance its read cursor says so and marks nothing it has not shown as read, and it exits nonzero, so the return keeps its catch-up gated until a check drains again and records the presentation, rather than clearing over outcomes a later drain would present again.
+The section's budgets count bytes in any locale, so a multibyte summary is cut on a whole UTF-8 character boundary to fit them.
+An unprocessed captain outcome is never adopted as processed, so a home that opts in mid-session cannot lose its first one.
+Anything main must act on while attended to move the work forward, such as a local-only branch to land or a pull request to merge, is a captain outcome on the host even when the captain asked not to hear about that work, reported once per unchanged situation (`bin/fm-branch-prompt.sh` "Verdict: routine or captain"), because a routine outcome opens no main turn.
+
+One limit: if the captain goes away and returns while an attended engine turn runs, and the host is terminated before that turn's `branch-outcome` wake is delivered, no immediate wake reaches main.
+The captain row is still durable, and the next drain presents it until it is acknowledged.

+It was measured on 2026-09-25 on macOS arm64 with Claude Code 2.1.283 as primary and engine (`sonnet`) and Pi 0.82.0 workers on `openai-codex/gpt-5.6-sol`, in a disposable lab home on a private tmux socket.
+The routine backlog and most of the away window's rows were appended to the store through `bin/fm-branch-outcome.sh append` to reach the shape of a real long window; the engine recorded the rest, including every captain outcome that woke main.

Subject: [PATCH 47/84] fix(bin): dedup directed source expansions in
 fm-pending-reply-lib (#5753)

Each '# shellcheck source=' directive makes ShellCheck's external-source
traversal expand that library's whole transitive graph again at the site.
fm-pending-reply-lib carried three directed lazy sources of fm-wake-lib and
two of fm-parent-channel-lib on identical per-call re-source sites, so one
file analysis peaked above 4 GiB and every caller (fm-watch, fm-teardown)
inherited the multiplier - the root cause of the PR #5732 Lint 1 OOM kill.

Keep the runtime '.' commands byte-identical: the lazy re-source under
'local STATE FM_WAKE_QUEUE FM_WAKE_QUEUE_LOCK' is real behavior. Drop the
duplicate directives so each library expands once per unit, and drop the
tmux/classify directives since classify already arrives through the kept
fm-wake-lib expansion and no tmux symbol is referenced here. The directive
above the lib-dir assignment is kept - it binds the bin/ prefix so the
undirected sites still resolve without SC1091.

Measured peak RSS, ShellCheck 0.11.0 -x on Linux arm64:
  bin/fm-pending-reply-lib.sh  4.06 GiB -> 1.96 GiB, zero findings

Subject: [PATCH 48/84] fix(bin): avoid bash 5.2 sibling $() in recovery mint
 and delivery log (#5773)

* fix: split bash 5.2 sibling $() in recovery mint and delivery log

Sibling command substitutions on one line can empty a recovery generation
under bash 5.2 when a CHLD trap is set. Mint pid/epoch sequentially, refuse
empty tokens before write, and clean delivery fields before printf.

* fix: split bash 5.2 sibling $() in recovery mint and delivery log

Sibling command substitutions on one line can empty a recovery generation
under bash 5.2 when a CHLD trap is set. Mint pid/epoch sequentially, refuse
empty tokens before write, and clean delivery fields before printf.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix: keep recovery mint failure semantics after sibling $() split

Remove the new pid/date refusal and grammar guard so a mint miss still
yields a grammar-valid token and a durable wake row, matching accepted
review intent. Drop the fake-failing-date case that locked in the refuse.

* no-mistakes(document): Point recovery-mint hazard comment at its regression test

+`fm-control.sh <id> interrupt` delivers Escape, which is the safe way to clear a wedged workspace-trust dialog for inspection without answering it.
+Escape on the external-imports dialog is different: it records a permanent decline (`hasClaudeMdExternalIncludesApproved: false`, `hasClaudeMdExternalIncludesWarningShown: true`) that `../../../bin/fm-claude-trust.sh` then correctly refuses to override on every later spawn for that project.
+Leave a pane showing the external-imports dialog alone and have a person answer it interactively instead of interrupting it.
+To recover from an already-recorded decline, remove both flags from the project's entry in `~/.claude.json` and approve the imports dialog once by hand.
 
 The once-per-machine bypass-permissions confirmation is a third, separate dialog, scoped to the machine rather than the path, and pre-registration does not address it.
 Never send Enter to that one either: it was observed rendering in the same shape as the trust dialog, with the selection on `No, exit` and the footer `Enter to confirm . Esc to cancel`, so Enter ends the session rather than accepting.

Subject: [PATCH 50/84] fix(bin): report the newest status event in the voice
 status reader (#5790)

Fixes #4756

The voice status reader in bin/fm_voice_records.py reports each
worker's state from the last non-blank line of its status log. When a
worker appends a status line and then a line of plain prose, the
reader reported "note" with the prose line instead of the declared
state, diverging from bin/fm-classify-lib.sh's shell scan.

Scan back through the tail for the newest line whose prefix is a
single lowercase verb-shaped word (letters and hyphens), and report
that event's verb instead of always taking the last line. An
unrecognised verb-shaped prefix still reports "note" rather than
letting an earlier recognised line answer for it, and free text with
no colon is skipped as prose. When the tail holds no such event, the
last line is reported exactly as before.

Subject: [PATCH 51/84] fix(bin): gate a self-announcing tool's
 update-available report on a newer version (#5786)

* fix(bin): stop reporting an already-installed version as an available update

An update announcement named its version first ("current -> new"), so
reading the first dotted number as the announced version compared the
current version against itself and always looked newer. Read the last
dotted number instead, and only report an available update when that
announced version is newer than the newest installed copy found; when
that version is already installed, report only PATH skew.

Fixes #5151

The dispatch profile's effort axis was recorded in task metadata but never
reached an OpenCode worker: the launch wrote only a permission grant into
the config it constructs.

OpenCode 1.18.32's config schema carries per-model reasoning effort as
agent.<name>.variant, so the chosen effort is now merged into the same
OPENCODE_CONFIG_CONTENT JSON as the default build agent's variant, keyed to
the resolved model. With no effort chosen the launch stays byte-identical.

Fixes #1373

* no-mistakes(review): gate OpenCode effort variant by model provider family

* no-mistakes(document): docs(opencode): note provider-family gating for effort variant

Subject: [PATCH 53/84] fix: stop cancelled validation runs from reporting
 false failures (#5815)

* fix: preserve cancellation as no verdict in crew state

Reuse the green-delivery safeguard for cancelled CI monitors and permit a skipped rebase. Other cancelled outcomes and coarse ledger records use the existing unknown state.

Four delivered-PR regressions failed before the fix and pass afterward. The isolated public resolver and fleet-summary tests prove that undelivered cancellation no longer creates a failure contradiction, while preserving historical records and the terminal_in_flight invariant. Evidence uses fixture no-mistakes responses, not a live daemon cancellation.

Update the existing coarse cancellation assertion from failed to unknown because it encoded this defect; retain its newest-run precedence check. Full fm-crew-state suite and pinned lint pass.

* fix(review): Verify PR disposition before reclassifying terminal validation runs

* fix(test): Add captured cancellation replay coverage for resolver and fleet

* fix(document): Clarify cancellation and terminal delivery documentation

Subject: [PATCH 54/84] fix: require declared waits for workers awaiting their
 own work (#5812)

* fix: declare worker background and pipeline waits

Require ship and scout workers to declare owned-work waits with the existing
paused verb before ending a turn or waiting on a pipeline or long command.
Keep the first-sight alert and existing liveness classification unchanged;
subsequent inspection follows the existing long pause cadence.

Validation: emitted brief regression failed before the instruction change
and passes afterward. Public watcher/drain regressions cover the first
alert, repeated wedge suppression, bounded rechecks, and undeclared idle
alarms using isolated backend fixtures. Brief suite, pinned lint, Bash
syntax, documentation inventory, and whitespace checks pass.
No real worker harness was exercised for wait behavior.

* fix(document): Clarify declared worker waits and documentation ownership

* fix(ci): Captain, fixed the cadence test to age both the declaration and first-alert throttle while preserving declaration identity. Reproduced the CI failure using stable identity; corrected tests pass with both stable identity and native macOS behavior. Focused ShellCheck and diff checks pass. Production behavior is unchanged; Linux CI was not rerun locally

 After handling all emitted wakes and reconciling the OPEN DECISIONS and UNREAD STATUS sections, run the exact generation-bound `--ack-through` command printed as `WAKE_ACK_REQUIRED`; interruption before that acknowledgement deliberately leaves the work durable for idempotent re-handling.
 A status line is a wake event, not current state; use `bin/fm-crew-state.sh` when current state matters, especially before re-escalating an old decision, blocker, or pause.

 That half is what keeps the ladder in the two cases where a parked supervisor-owed gate is really the crewmate's move: a decision that has already been answered, where `fm-send --resolve-key` closed it at answer time while the gate stays parked until the crewmate relays it, and a crewmate that parked at such a gate and went quiet before escalating it at all, where nobody was ever told.
 A `blocked` record is not that evidence, since a blocker is an obstacle the crew reported rather than an unanswered question, and a different action clears it.
 Every way the fold can come back empty, including an unreadable status file, leaves the unchanged escalation schedule in place rather than taking the ladder away.
-Each kind of wait carries the human it is on and the action that clears it as data alongside the verdict, rather than as wording chosen per branch where the recheck is written, so a new kind of evidence cannot reach the deferral without deciding both.
-The deferral refuses a record that does not carry all of them and escalates as it would have, because deferring on a half-filled record is what would print the wrong human or an action that clears nothing.
-The three block on different people: a `paused:` declaration is owed by an external dependency the worker named and asks the reader to confirm the wait still holds, a hold is owed by the captain reading the recheck and asks them to answer the held decision or release the hold, and a parked gate is owed firstmate's `ask-user` decision and asks for that finding to be decided and relayed to the crewmate, because ask-user findings are routed to firstmate, which decides most of them itself, and one it escalates becomes a captain-held transfer that the hold record already covers.

 Wording any of them as another would point the reader away from the one action that clears it.
 A wait with a written record is aged from the status file, since that is when the worker wrote the line; anchoring on a per-window marker instead would let a churning display reset the cadence.
 A parked gate has no such record - the worker never wrote the wait down - so its recheck publishes no wait age at all rather than one read from the quiet window, which this deferral resets on every pass and which would therefore report the same small number for a gate of any age.

 Crew status files are append-only wake-event logs, not current-state fields.
 Because of that, a per-wake read of only the latest line can bury an earlier still-open `needs-decision`/`blocked` under later unrelated appends; `fm-wake-drain.sh` prints a separate, fleet-wide OPEN DECISIONS section on every presentation (including the empty-queue path session-start relies on), built through `fm-classify-lib.sh`'s cursor-backed incremental scan using the authoritative `status_open_decisions` fold semantics so the buried decision keeps surfacing until that fold closes it while each presentation folds only new status-log appends.
 The drain coordinates that fold and its annotations through a locked fleet-wide snapshot whose `.status-presentation-cursor` manifest records each status file's identity plus independent annotation and outcome-backstop byte offsets.

Subject: [PATCH 55/84] fix: bound ShellCheck to one canonical root per process
 (#5770)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(bin): bound each lint root in its own ShellCheck process

CI job "Lint 1" died twice at about ten minutes because the two shard
workers each packed about 110 canonical roots into one unbounded ShellCheck
process, and a byte-weight rebalance moved the analysis-heavy fm-watch.sh
into a partition with other heavy roots, so the pair outgrew the 16 GiB
runner before anything could name a culprit.

Run one canonical root per ShellCheck process under an enforced envelope:
a wall deadline plus terminate-then-kill grace via the shared
fm-timeout-lib.sh watchdog, and a per-root rlimit spec applied inside the
child before exec (default a 4 GiB address-space cap, so two workers stay
inside a 16 GiB job with headroom). A root that exceeds the envelope fails
by name with a recorded reason - timeout, memory, signal, or
limit-unavailable - instead of taking the runner down. The per-root
watchdog runs in its own process group so the owner's group sweep cannot
orphan the bounded subtree, and fm_exec_timed now starts the same
escalation when its parent dies before it can be signalled.
FM_LINT_REQUIRE_BOUNDS=1, set in CI, refuses the run outright when a
configured bound cannot be enforced on the host rather than lint uncapped.
Each root's begin/end, reason, duration, and peak RSS stream to stderr in
partition mode and append to a retained <telemetry>.roots.tsv sidecar
uploaded beside the partition telemetry.

Coverage is unchanged: pinned ShellCheck 0.11.0, --norc, --external-sources
full analysis, complete and disjoint partition inventory, workflow lint,
and the backend-purity check, with byte-identical diagnostics across
jobs=1/2 proven by tests/fm-lint.test.sh.

* fix(bin): fail closed on unenforceable lint bounds and size the cap

Required-bounds mode (FM_LINT_REQUIRE_BOUNDS=1, set by CI) now refuses the
run with named errors before any root starts: a missing fm-timeout-lib.sh,
a watchdog that cannot actually bound a probe command, or a host that
rejects the address-space limit all stop the run rather than lint uncapped.
The generalized FM_LINT_ROOT_RLIMITS flag:value interface is replaced by a
single FM_LINT_ROOT_MEMORY_KIB, and the roots sidecar and telemetry record
the run's final exit status after backend-purity and workflow checks
instead of the pre-check lint status.

The default cap is 6 GiB of address space per root, not 4 GiB: ulimit -v
bounds virtual address space rather than resident memory, and ShellCheck's
GHC runtime keeps roughly a third of that space as reservation, so 6 GiB
yields about a 4 GiB working heap budget. A Linux measurement during this
change showed eleven real canonical roots running out of memory under the
earlier 4 GiB cap while the largest passing root peaked near 2.8 GiB
resident; two 6 GiB roots plus runner overhead still fit the 16 GiB job.
Roots that still exceed the cap keep failing by name, and the sidecar's
per-root peak RSS keeps roots approaching the budget visible.

tests/fm-lint.test.sh now proves the memory primitive where it can be
proven: on hosts that accept ulimit -v a perl allocator is refused under a
256 MiB limit and reported by name as a memory death, the pinned ShellCheck
lints a small file under the configured cap and is named when a far smaller
cap binds it, and a watchdog-less copy refuses under REQUIRE_BOUNDS; the
bounded cases skip on macOS, which cannot enforce the address-space limit.

* no-mistakes(review): Prove memory cap binds, pass watchdog owner, drop unused modes

* no-mistakes(review): Capture watchdog owner before startup for every fm_exec_timed caller

* no-mistakes(document): Clarify bounded lint documentation and telemetry

* no-mistakes(document): Correct bounded lint documentation and sidecar path

* docs(bin): restore the per-root memory cap sizing rationale

The pipeline's document step rewrote the ROOT_MEMORY_KIB comment and
dropped the sizing reasoning the change is required to record: address
space vs resident memory, the GHC reservation share, the measured 4 GiB
failures and ~2.8 GiB peak, and the two-roots-plus-runner capacity
arithmetic. Restore it beside the default while keeping the corrected
"not a resident-memory ceiling" framing.

* no-mistakes(review): Document memory cap RSS reduction threshold and first candidate

* no-mistakes(review): Scope owner-death escalation docs to the perl watchdog

* no-mistakes(document): Clarify bounded lint and timeout documentation

* no-mistakes(review): Install perl watchdog signal handlers before forking the command

* no-mistakes(document): Correct bounded lint documentation and stale watcher comments

* no-mistakes(ci): Fixed the supervision-host test’s obsolete expectation: the watchdog now reaps an engine when its host dies. The timeout and supervision-host tests pass locally; the watcher test also passes locally. Lint 1 and 2 remain unresolved: seven canonical roots exceeded the required 6 GiB address-space cap in CI. I did not raise the cap, exempt roots, or reduce source-following coverage to make those failures disappear

* no-mistakes(ci): The two lint checks failed when eight canonical roots hit the enforced memory cap. I reduced repeated ShellCheck source-graph expansion while keeping runtime imports and the canonical root inventory intact. Pinned ShellCheck passes for all changed roots; the relevant local tests pass. The 6 GiB Linux CI run remains unverified

* no-mistakes(review): Restore source directives, raise cap to 8 GiB, classify OOM

* no-mistakes(review): Classify memory deaths from root stderr, not source excerpts

* no-mistakes(review): Match only whole runtime memory-error lines for memory reason

* no-mistakes(document): Clarify lint memory classification in script documentation

* no-mistakes(ci): Fixed both lint checks’ memory-limit failure: each CI lint job now runs one root at a time with a 12 GiB address-space cap. Kept the local two-worker default and updated the sizing comment and test expectation. The lint tests and workflow validation pass locally; Linux CI remains to confirm the heavy roots

+`bin/fm-lint.sh` owns two canonical CI partitions, each running full source-aware ShellCheck analysis, workflow validation, and backend-purity checks.
+CI requires its per-root bounds, so an unenforceable deadline or address-space limit refuses lint rather than running uncapped; the script header owns the envelope and per-root execution contract.
 Its `--list-files` interface exposes partition membership; `tests/fm-lint.test.sh` verifies complete/disjoint executed roots and unchanged analysis flags.
-The workflow uploads each partition's quiet telemetry to distinguish analysis cost, memory use, and host contention.
+The workflow uploads each partition's quiet telemetry plus its per-root lifecycle sidecar to distinguish analysis cost, memory use, and host contention.
 No fast mode, path skips, reduced checks, or paid runner provisioning is part of this layout.
 
 The performance objective is a complete green run under fifteen minutes including start delay: roughly twelve minutes of longest-path execution, at most two minutes of runner delay, and less than one minute of other overhead.

Subject: [PATCH 56/84] fix: bound watcher cleanup wait on the downtime-marker
 lock (#5732)

* fix(bin): bound the watcher cleanup marker-lock wait

tests/fm-watch-triage.test.sh intermittently failed serial CI shard 1
with "watcher pid <pid> did not exit within 10s of TERM". The watcher
had processed the TERM and was inside watcher_cleanup, where the
recovery-marker publish waits on state/.watcher-down.lock through an
unbounded fm_lock_acquire_wait. A live foreign holder of that lock
leaves the TERM'd watcher spinning in its own EXIT trap until the lock
frees or a second signal short-circuits the trap.

fm_recovery_transition now takes an optional bound and both
release-lock paths plus publish honour it through a new in-process
fm_lock_acquire_wait_max. watcher_cleanup passes
FM_WATCHER_CLEANUP_LOCK_BOUND (default 2s); on timeout the publish is
skipped, the singleton stays behind as ordinary dead-pid evidence, and
the next arm's clear-stale-lock still republishes it.

Regression test drives a real watcher with .watcher-down.lock held by
a live foreign process and asserts a single TERM still stops it.

* no-mistakes(review): Parse watcher cleanup lock bound as decimal, zero defaults

* no-mistakes(review): Pin cleanup bound tests to observed marker-lock contention

* no-mistakes(document): Document bounded watcher cleanup and recovery

* no-mistakes(document): Clarify bounded watcher cleanup and recovery documentation

* no-mistakes: apply agent fixes

* no-mistakes(review): Arm marker-lock FIFO before TERM; drop FM_TEST_ONLY_LATE

* no-mistakes(review): Hold marker lock through a failed cleanup acquire

 Once per poll the watcher checks that its home, its state directory, and its own code root still exist, and exits with a logged reason when one is gone, scoped to itself alone, so a torn-down temporary home or a discarded checkout never leaves an orphan watcher behind.
 The watcher uses bash's native fatal handling for HUP and TERM, including during a blocked poll, so both run its EXIT cleanup.
 `watcher_stop_signals` in `bin/fm-watch.sh` owns the signal-handling rationale.
+The EXIT cleanup bounds its wait for `state/.watcher-down.lock` while persisting recovery state with `FM_WATCHER_CLEANUP_LOCK_BOUND` (default 2 seconds).
+Only positive decimal integers are accepted, including leading-zero forms such as `08`; empty, non-numeric, and zero values (including `00`) fall back to 2 seconds.
+A live foreign holder therefore cannot strand a TERM'd watcher in this marker-lock wait: on timeout the recovery transition fails without releasing the singleton, leaving dead-pid stale evidence for the next arm to republish and clear.

Subject: [PATCH 57/84] test: stop the remote secondmate e2e watcher before
 temp-root cleanup (#5845)

* test: stop the leaked unreachable watcher before remote e2e cleanup

The remote secondmate lifecycle e2e backgrounded fm-watch.sh through the
remote_env shell function, so $! named the function's subshell rather than
the watcher. Killing that subshell left the unreachable-leg watcher running,
and its one-second liveness probe kept invoking the fake ssh, which rewrites
ssh.count in the temp root. When a probe landed while the EXIT trap was
removing the root, rm failed with "Directory not empty" after every
assertion had passed.

Exec the watcher from the backgrounded function so the recorded pid is the
watcher itself, and assert the stopped watcher stops probing and writing its
state. Cleanup also stops a watcher left running by a failed assertion and
removes the root through fm_test_remove_tree, so a run that fails before
retirement does not strand the read-only spawn hooks directory.

Closes #5836

* no-mistakes(review): Clear reaped watcher PIDs and restore plain temp-root removal

* no-mistakes(review): Let in-flight probe settle before stopped-watcher baseline

 `data/captain-shared.md` is main-authoritative in the primary home and read-only in secondmate homes.
 Its primary file header must state that the file is main-authoritative, read-only in secondmate homes, must not be edited there, and that new captain-preference discoveries are routed to the main firstmate through marked status or a document pointer.
 Every propagation point converges the secondmate copy to the primary bytes; when the primary file is absent, any existing secondmate copy is quarantined and removed so absence converges too.
+Both the local helper and the remote receiver compare the destination against the generation each last published there, so an untouched inherited copy is replaced quietly instead of being reported as drift.
+A destination matching neither the primary bytes nor that recorded generation is quarantined to a collision-safe private dated sibling file before replacement, with a `SECONDMATE_SYNC:` diagnostic naming the home and quarantine artifact on the local route, so genuine local edits and interrupted publication keep a recovery copy.
 The helper rejects unsafe directories, symlinked or nonordinary source or destination artifacts, and hardlinked destination files.
 Between propagation runs, the secondmate copy is filesystem read-only; the helper may make its owned destination writable only around a guarded update and restores read-only mode on success, unchanged bytes, and recoverable failure paths.
-Before replacing divergent secondmate bytes, the helper hash-compares source and destination, quarantines the secondmate-local version to a collision-safe private dated sibling file, and emits a `SECONDMATE_SYNC:` diagnostic naming the home and quarantine artifact.
 Never copy any secondmate `data/captain-shared.md` back into the primary.
 Keep each home's `data/captain.md` domain-local.
 After first propagation to an existing home, trim that home's local `data/captain.md` by hand to domain-specific content plus pointers to `data/captain-shared.md`; do not automate or silently delete private content.

Subject: [PATCH 59/84] docs: restructure calm.md for readability (#5604)

* docs: make calm easier to read

Restructure the Calm mode prose into sections, lists, and tables without changing documented behavior. Every original heading, anchor, fenced code block, inline-code span, link target, number, and quoted string is preserved.

* docs: restore reload case in calm override lead-in

The Built-in tool override collisions lead-in covers a session that reloads with Calm already on, as the original text did.

 # Calm mode
 
 Calm is Firstmate's conversation-only transcript presentation toggle.
-It is fully supported on Pi, and available on Claude Code behind that harness's default-off early-access function-hooks flag, as the [Claude Code](#claude-code) section below describes.
-It is off by default, and the last `/calm` choice persists for the effective Firstmate home across session starts and resumes on either harness, through the one shared preference file [`configuration.md`](configuration.md#calm-preference-configcalm) owns.
-Across both harnesses, Calm evaluates each settled assistant text block from a model step that stopped to call tools, or exhausted its token limit while carrying tool calls.
-It hides a block only when its raw text contains no newline and its trimmed length is below `CALM_PRESERVE_MIN_CHARS` (240); a newline or at least 240 trimmed characters preserves the block as substantive captain-facing content, while streaming text and the genuine reply that ends a response remain visible.
+This page is for operators who turn Calm on and need to know what it hides and keeps visible on Pi and on Claude Code, and which file owns each part of that behavior.
+
+## Harness support and default
+
+| Harness | Support |
+| --- | --- |
+| Pi | Fully supported. |
+| Claude Code | Available behind that harness's default-off early-access function-hooks flag, as the [Claude Code](#claude-code) section below describes. |
+
+Calm is off by default.
+The last `/calm` choice persists for the effective Firstmate home across session starts and resumes on either harness.
+Both harnesses keep that choice in the one shared preference file that [`configuration.md`](configuration.md#calm-preference-configcalm) owns.
+
+## Shared preservation rule for assistant text
+
+Across both harnesses, Calm evaluates each settled assistant text block from a model step that stopped to call tools, or that exhausted its token limit while carrying tool calls.
+Calm hides such a block only in the first case below:
+
+| Settled block | Result |
+| --- | --- |
+| Raw text contains no newline, and trimmed length is below `CALM_PRESERVE_MIN_CHARS` (240) | Hidden. |
+| Raw text contains a newline, or trimmed length is at least 240 | Preserved as substantive captain-facing content. |
+
+Streaming text and the genuine reply that ends a response remain visible.
 
 ## Pi
 
-While Calm is active and an agent run is under way, Calm hides Pi's built-in `Working...` row and shows a small two-row animated boat in its place, and no separate Calm status row is added.
-The water fills the usable width with low one-cell Unicode bars, all in standard ANSI blue, so the swell shows through bar height alone.
-The asymmetric three-cell `◿│◣` sail is centered over the five-cell `╲▁▁▁╱` hull, and the whole boat, both sail halves, mast, and hull, is one standard ANSI yellow, with the hull's zero-height interior keeping the swell continuous beneath the boat.
-The boat is deliberately calm: it moves one column every 880ms, while the long smooth wave advances one quarter-cell every 220ms so the surface stays alive between boat steps.
-Deterministically varied half-waves stay between nine and thirteen cells, and the boat remains phase-locked inside a broad zero-height trough through movement and edge reversals.
-Every resize reflows the sprite without wrapping, and it disappears when the run settles, aborts, or fails.
+### Working boat
+
+While Calm is active and an agent run is under way, Calm hides Pi's built-in `Working...` row and shows a small two-row animated boat in its place.
+No separate Calm status row is added.
+While Calm is off, Pi's stock working row is left exactly as Pi renders it.
+
+The boat looks like this:
+
+- The water fills the usable width with low one-cell Unicode bars, all in standard ANSI blue, so the swell shows through bar height alone.
+- The asymmetric three-cell `◿│◣` sail is centered over the five-cell `╲▁▁▁╱` hull.
+- The whole boat is one standard ANSI yellow, including both sail halves, the mast, and the hull.
+- The hull's zero-height interior keeps the swell continuous beneath the boat.
+- Very narrow terminals fall back to a smaller deterministic sprite.
+
+### Boat motion
+
+The boat is deliberately calm.
+It moves one column every 880ms.
+The long smooth wave advances one quarter-cell every 220ms, so the surface stays alive between boat steps.
+Deterministically varied half-waves stay between nine and thirteen cells.
+The boat remains phase-locked inside a broad zero-height trough through movement and edge reversals.
+Every resize reflows the sprite without wrapping.
+The boat disappears when the run settles, aborts, or fails.
+
+### Boat position between working periods
+
 Within one Pi session and Calm extension lifetime, the next working period resumes the boat from its last rendered column and travel direction rather than restarting at the left edge.
-Hidden elapsed time does not advance the animation, and a resize while hidden clamps the frozen boat to the new width without changing its valid travel direction.
+Hidden elapsed time does not advance the animation.
+A resize while hidden clamps the frozen boat to the new width without changing its valid travel direction.
 A fresh Pi session or new Calm extension lifetime starts at the normal initial position.
-Very narrow terminals fall back to a smaller deterministic sprite.
-While Calm is off, Pi's stock working row is left exactly as Pi renders it.
-Calm hides collapsed thinking labels, the mid-turn assistant working-note blocks governed by the shared preservation rule above, the shells for the Pi built-in tool names Calm owns, the `fm_watch_arm_pi` and `fm_branch_outcomes` tool shells, and canonically classified Firstmate operational user rows.
-Pi applies that rule independently to each text block, so a short working note can hide beside preserved substantive content in the same message.
-A working note is briefly visible while it streams before its settled row collapses.
-The narration is hidden only from the live transcript presentation, and remains in the message, model context, session storage, and `/export` artifacts.
-The operational inputs Calm classifies remain ordinary user-role messages, while Pi's transcript layout renders their complete rows at zero height.
-While a turn runs, Calm also keeps those Firstmate inputs out of Pi's queued-message listing, and the captain's own queued messages stay listed.
-Escape and the dequeue key return only the captain's queued messages to the editor; hidden Firstmate inputs stay queued in their original order and are never shown as raw text or dropped.
-When Escape, or navigating the session tree, stops a run with Firstmate inputs still queued, Calm starts one new turn to deliver them and shows the one-line notice `Firstmate supervision continues in a new turn.`
-Inputs held behind a running compaction stay there until Pi sends them after compaction, so they start and announce no turn of their own.
+
+### What Calm hides on Pi
+
+Calm hides these rows:
+
+- Collapsed thinking labels.
+- The mid-turn assistant working-note blocks governed by the [shared preservation rule](#shared-preservation-rule-for-assistant-text) above.
+- The shells for the Pi built-in tool names Calm owns.
+- The `fm_watch_arm_pi` and `fm_branch_outcomes` tool shells.
+- Canonically classified Firstmate operational user rows.
+
+Pi applies the preservation rule independently to each text block.
+A short working note can therefore hide beside preserved substantive content in the same message.
+A working note is briefly visible while it streams, before its settled row collapses.
+
+The narration is hidden only from the live transcript presentation.
+It remains in the message, model context, session storage, and `/export` artifacts.
+
+The operational inputs Calm classifies remain ordinary user-role messages.
+Pi's transcript layout renders their complete rows at zero height.
 The session-start nudge remains on its existing non-displayed custom-message path.
 
-Outside Pi's same-name built-in override collision described below, Calm changes presentation only.
-Calm's built-in wrappers preserve Pi's execution behavior, and input delivery, ordering, model context, session storage, diagnostics, and `/export` and `/share` operation remain unchanged.
+### Queued Firstmate inputs on Pi
+
+While a turn runs, Calm also keeps those Firstmate inputs out of Pi's queued-message listing.
+The captain's own queued messages stay listed.
+Escape and the dequeue key return only the captain's queued messages to the editor.
+Hidden Firstmate inputs stay queued in their original order and are never shown as raw text or dropped.
+When Escape, or navigating the session tree, stops a run with Firstmate inputs still queued, Calm starts one new turn to deliver them.
+Calm then shows the one-line notice `Firstmate supervision continues in a new turn.`
+Inputs held behind a running compaction stay there until Pi sends them after compaction, so they start and announce no turn of their own.
+
+### What stays unchanged on Pi
+
+Outside Pi's same-name built-in override collision described in [Pi compatibility](#pi-compatibility) below, Calm changes presentation only.
+Calm's built-in wrappers preserve Pi's execution behavior.
+Input delivery, ordering, model context, session storage, diagnostics, and `/export` and `/share` operation remain unchanged.
 Every hidden Firstmate input remains available to the model and in serialized session data and exported artifacts.
 Legacy operational custom messages remain in session data and Pi's sidebar tree, although the main HTML transcript may omit them.
 Toggling Calm off restores ordinary rendering, and `Ctrl+O` expansion state is preserved.
 
+### What stays visible on Pi
+
 Pi's supported presentation API does not expose a global transcript filter.
-Expanded reasoning and its reserved spacing, built-in tool images, user-bash rows, skill and summary rows, generic status notices, and other arbitrary custom-tool or extension rows remain visible.
+These rows remain visible:
+
+- Expanded reasoning and its reserved spacing.
+- Built-in tool images.
+- User-bash rows.
+- Skill and summary rows.
+- Generic status notices.
+- Other arbitrary custom-tool or extension rows.
+
 These are supported-API boundaries rather than hidden-content failures.
 
 ## Pi compatibility
 
-Calm has no numeric Pi version minimum or maximum and never refuses Pi solely because its version is newer than a previously verified version.
-The collapsed-thinking, operational-user-row, and queued-operational-row presentation adapters probe the exact Pi API seam they patch when Calm loads.
-If Pi removes one of those seams, Calm logs a diagnostic naming the unavailable adapter and skips only that adapter; `/calm`, the other adapters, and unrelated Pi extensions remain available.

+### Session check for queued inputs
+
 Keeping hidden queued inputs across Escape also needs members of Pi's live session, which exist only once a session runs.
 Calm checks them for each session on its first queued-listing draw, before hiding anything.
-A session missing any of them keeps its queued rows and Escape exactly as stock and shows one warning, and `tests/fm-calm-pi-queue-retention-live-e2e.test.sh` fails naming the installed Pi version.
+A session missing any of them keeps its queued rows and Escape exactly as stock, and shows one warning.
+In that case `tests/fm-calm-pi-queue-retention-live-e2e.test.sh` fails naming the installed Pi version.
+
+### Built-in tool override collisions
 
 Calm's built-in tool presentation (`bash`, `read`, `edit`, `write`, `grep`, `find`, `ls`) shares Pi's single, unmerged override slot per name with any other extension that overrides the same tool.
-While the persisted Calm preference is off, Calm registers none of those overrides and therefore contests no built-in tool name.
-The first time Calm turns on in a session that started off, it claims every built-in name no other extension already owns, leaves every contested tool intact and callable, and displays a prominent warning naming the tools it skipped.
-Tool-call rows already on screen before that first toggle do not retroactively collapse; later rows for the names Calm claimed use Calm presentation.
-When a session starts or reloads with Calm already on, Calm must instead register all seven overrides synchronously so Pi can render restored rows with them.
-Pi provides no ownership check early enough for that load-time path, and the first registrant wins the complete tool definition.
-If the other extension wins, a session-start console diagnostic names the tool and winning extension; if Calm wins, Pi does not expose the losing registration, so the other extension's override is unavailable and cannot be named.
+How Calm handles that shared slot depends on whether Calm was already on when the session started or reloaded.

+### The firstmate-calm mod
+
+Calm on Claude Code is the `firstmate-calm` mod under `.claude/mods/firstmate-calm`.
+The mod is a Claude Code plugin whose whole behavior lives in one function-hooks module.
 The trusted project auto-loads the mod through the `.claude/skills/firstmate-calm` entry (a symlink into `.claude/mods`), so no `--plugin-dir` or marketplace install is needed.
 
-With the flag on, the mod registers `/calm`, which toggles the same per-home preference Pi's `/calm` uses, so one choice applies on both harnesses.
-The toggle answers with a transient "Calm on" or "Calm off" notice under the prompt rather than a transcript row, and a preference that cannot be written leaves the current choice unchanged and says so in that notice.
-While Calm is on, the stock working row (`Sauteing... (12s · 300 tokens)`) becomes the same two-row sailboat Pi draws, from the same shared sprite geometry: it fills the row inside the transcript margin, repaints on the boat's 220ms cadence with the hull moving every 880ms, reflows on resize, and appears and disappears exactly where the stock row would.
-On Claude Code the boat is painted in Claude Code's own theme colors rather than Pi's standard ANSI codes: every water cell takes the spinner blue of the active theme family (`#93a5ff` on a dark theme, `#5769f7` on a light one) and the whole boat, both sail halves, mast, and hull, takes the Claude orange of the stock spinner (`#d77757`).
-The family follows the `theme` setting by its prefix, `dark` or `light`, is re-read when the theme changes, and uses the light set as the both-readable fallback for `auto`, custom, missing, or unreadable values; the Pi extension keeps its standard ANSI blue and yellow.
+### Enabling function hooks
+
+Claude Code's early-access function-hooks surface is off by default.
+Claude Code can load modules through its rollout flag, or per session with `CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1`.
+The mod independently requires that environment variable to equal `1` before doing anything.
+Firstmate never sets that flag in any project or user settings.
+Enabling it is each captain's own explicit opt-in.
+
+Without that exact value, the mod is a complete no-op, even if Claude Code's rollout flag loads the module:
+
+- There is no `/calm` command.
+- The mod reads neither the preference nor the transcript.
+- The mod runs no timer.
+- Every drawing stays exactly as Claude Code draws it, whatever `config/calm` says.
+
+### Toggling Calm on Claude Code
+
+With the flag on, the mod registers `/calm`.
+It toggles the same per-home preference Pi's `/calm` uses, so one choice applies on both harnesses.
+The toggle answers with a transient "Calm on" or "Calm off" notice under the prompt rather than a transcript row.
+A preference that cannot be written leaves the current choice unchanged, and the notice says so.

+
+### What Calm hides on Claude Code
+
 Tool rows, tool result blocks, and folded tool groups draw at zero height, so a turn that used tools takes the same space as one that did not.
-A user row whose text the canonical operational-input parser recognizes, a Firstmate session-start, watcher, turn-end guard, away-supervisor, launch-brief, or branch-outcome envelope, a from-firstmate routed message, or one of the narrow pre-protocol shapes kept for old transcripts, draws at zero height; other user rows, including near misses such as a quoted or ASCII-only marker, stay visible unless backed by an operational record as described below.
-Claude Code removes the U+2063 that starts those envelopes from every submitted prompt, so Firstmate delivers its away-mode escalations to a Claude Code primary as the record-backed doorbell `bin/fm-operational-input.sh` owns: a plain line naming a record under the home's `state/operational-inbox` that holds the envelope.
-Calm reads that record through the mod's file API and hides the doorbell row only when the record holds a current envelope, so a doorbell-shaped line naming no such record stays visible; a verbatim copy of a live doorbell line, pasted back while its record still exists, is treated as Firstmate's and hides.

 # Primary turn-end supervision guard
 
+This doc explains the check that stops a primary Firstmate session from ending a turn while its work has no live supervision, and how each harness enforces that check at its turn boundary.
+It is for operators working out why a turn end was blocked or followed up, and for anyone changing a harness turn-end hook.
+
 This is the authoritative current contract for the "no turn ends blind" primary backstop referenced from AGENTS.md section 8.
 The predicate lives in `bin/fm-turnend-guard.sh`.
 Primary scope lives in `bin/fm-primary-scope-lib.sh`, shared with the native session-start adapters in [`sessionstart-nudge.md`](sessionstart-nudge.md).

 ## Current invariant
 
 `bin/fm-guard.sh` is a pull-based warning that runs only when another supervision command invokes it.
 The turn-end guard closes the remaining gap at the primary's own turn boundary.
-When work, a process-event source, a registered custom check, or Relay polling needs supervision at that boundary and no identity-matched watcher has a fresh beacon, the harness integration must either block the turn end or force one bounded follow-up that uses the recovery instruction from the emitted session-start protocol.
+
+The guard acts at that boundary when both of these hold:
+
+- Work, a process-event source, a registered custom check, or Relay polling needs supervision.
+- No identity-matched watcher has a fresh beacon.
+
+The beacon is `state/.last-watcher-beat`, which `bin/fm-watch.sh` touches every cycle, as [Guard grace and the poll cadence](#guard-grace-and-the-poll-cadence) describes.
+When the guard acts, the harness integration must do one of two things:
+
+- Block the turn end.
+- Force one bounded follow-up that uses the recovery instruction from the emitted session-start protocol.
+
 The mid-turn pull warning uses the model-aware supervision verdict described below, while the turn-end guard keeps the PID-strict watcher predicate.
-Away and quiet mode are the one place the turn-end guard accepts a different supervisor: while `state/.afk` exists, in either mode (`bin/fm-wake-lib.sh`'s `fm_afk_mode`), the daemon owns supervision, so a live identity-matched daemon with a fresh beacon satisfies that boundary in place of a watcher process holding the lock.
-The guard remains a backstop; [`watcher-continuity.md`](watcher-continuity.md) owns normal continuity.

 ## Guard predicates
 
+The turn-end guard checks primary scope first, then supervision need, then watcher health.
+The mid-turn pull warning in `bin/fm-guard.sh` judges watcher health differently, as described under [pull-warning verdict by supervision model](#pull-warning-verdict-by-supervision-model).
+
+### Primary scope
+
 The guard first calls the shared primary scope.
 A secondmate home runs its own primary Firstmate session, so a genuine `.fm-secondmate-home` marker includes it whether the home is a linked worktree or plain clone.
-The marker must be a regular non-symlink file whose whitespace-stripped first line is a non-empty identifier containing only letters, digits, dots, underscores, and dashes.
+The marker must meet both of these conditions:
+
+- It is a regular non-symlink file.
+- Its whitespace-stripped first line is a non-empty identifier containing only letters, digits, dots, underscores, and dashes.
+
 An unmarked checkout or invalid marker falls through to the git-dir check.
 That check keeps crewmate and scout linked worktrees inert because their git dir differs from their git common dir.
 It also requires `AGENTS.md`, `bin/`, and the effective state directory.
 
+### Supervision need
+
 For an in-scope primary, the guard counts in-flight work from `state/*.meta`.
-Registered `state/procevent/*.source` records also require supervision even though they have no task metadata.
+These sources also count toward supervision need:
+
+- Registered `state/procevent/*.source` records require supervision even though they have no task metadata.
+- Every mode treats `state/x-watch.check.sh` as supervision need, so Relay polling remains guarded without an in-flight task.
+- A custom check registered with `bin/fm-check-register.sh` counts the same way, so an operator's home-level poll keeps running after the last task is torn down.
+
 The default cross-harness mode exits silently with no supervision need.
-Every mode treats `state/x-watch.check.sh` as supervision need, so Relay polling remains guarded without an in-flight task.
-A custom check registered with `bin/fm-check-register.sh` counts the same way, so an operator's home-level poll keeps running after the last task is torn down.
-Otherwise it calls `fm_watcher_healthy <state-dir> <watch-path> [grace-seconds] [home]` from `bin/fm-wake-lib.sh`, the same PID-strict identity-matched lock and fresh-beacon check used by `bin/fm-watch-arm.sh`: a stale beacon blocks even when a watcher pid is live, and a fresh leftover beacon blocks when the lock is missing, dead, or identity-mismatched.
-The turn-end guard needs that strict check because it fires at the turn boundary, where the auto-arm is bringing a fresh watcher up for the upcoming idle period, and it cooperates with that arm rather than trusting a beacon left by the cycle that just ended.
+
+### Strict watcher check at the turn boundary
+
+Otherwise the guard calls `fm_watcher_healthy <state-dir> <watch-path> [grace-seconds] [home]` from `bin/fm-wake-lib.sh`.
+It is the same PID-strict identity-matched lock and fresh-beacon check used by `bin/fm-watch-arm.sh`.
+Under that check:
+
+- A stale beacon blocks even when a watcher pid is live.
+- A fresh leftover beacon blocks when the lock is missing, dead, or identity-mismatched.
+
+The turn-end guard needs that strict check because it fires at the turn boundary.
+At that boundary the auto-arm is bringing a fresh watcher up for the upcoming idle period.
+The guard cooperates with that arm rather than trusting a beacon left by the cycle that just ended.
+
+### Foreign session-lock owner
+
 When an active home instead has a live session lock held by a verified harness that the current session does not own, the Claude guard emits a read-only ownership diagnostic and allows the turn to end safely.
-Ownership is the shared `fm_session_lock_owned_by_self` verdict in `bin/fm-session-lock-lib.sh`: the recorded pid is a member of the current session's contiguous harness ancestry, or the trusted Claude session id recorded beside the lock in `state/.lock-session` matches this hook's own environment while the recorded pid is still a live harness.
-That second signal keeps a background Claude session owning its own lock after the transient helper chain between its hooks and its recorded owner is recycled; the library's header owns the trust gate (`CLAUDE_PID` must be a Claude-shaped member of the current run) and `bin/fm-lock.sh` owns the sidecar and the line-1 anchor it records for such a session.
-That Claude session cannot arm or repair the home without stealing the live owner's lock, so blocking it would create an unbounded loop; the lock-owning session remains responsible for restoring supervision.
-Malformed, absent, dead, or ancestry-uncertain lock records do not satisfy this Claude-specific exception and retain the ordinary guard behavior, and a missing or mismatched sidecar or an untrusted id adds nothing to the verdict, so a live owner outside the ancestry still takes this exit exactly as before.
-`bin/fm-guard.sh`, the pull warning, instead uses the model-aware `fm_watcher_supervision_verdict` from the same library, because it fires mid-turn when the auto-arm model runs no watcher at all.
+
+Ownership is the shared `fm_session_lock_owned_by_self` verdict in `bin/fm-session-lock-lib.sh`.
+The current session owns the lock when either of these holds:
+
+- The recorded pid is a member of the current session's contiguous harness ancestry.
+- The trusted Claude session id recorded beside the lock in `state/.lock-session` matches this hook's own environment while the recorded pid is still a live harness.
+
+That second signal keeps a background Claude session owning its own lock after the transient helper chain between its hooks and its recorded owner is recycled.
+The library's header owns the trust gate (`CLAUDE_PID` must be a Claude-shaped member of the current run).
+`bin/fm-lock.sh` owns the sidecar and the line-1 anchor it records for such a session.
+
+A Claude session that does not own the lock cannot arm or repair the home without stealing the live owner's lock, so blocking it would create an unbounded loop.
+The lock-owning session remains responsible for restoring supervision.
+
+The exception has these limits:
+
+- Malformed, absent, dead, or ancestry-uncertain lock records do not satisfy this Claude-specific exception and retain the ordinary guard behavior.
+- A missing or mismatched sidecar or an untrusted id adds nothing to the verdict, so a live owner outside the ancestry still takes this exit exactly as before.
+
+### Pull-warning verdict by supervision model
+
+`bin/fm-guard.sh`, the pull warning, instead uses the model-aware `fm_watcher_supervision_verdict` from `bin/fm-wake-lib.sh`.
+It needs a different verdict because it fires mid-turn, when the auto-arm model runs no watcher at all.
+The verdict depends on the supervision model.
+
+#### Claude Stop auto-arm model
+
 Under the Claude Stop auto-arm model a beacon fresh within grace is healthy even with no live watcher process.
-A stale beacon is still healthy while `fm_autoarm_midturn_healthy` in `bin/fm-wake-lib.sh` proves a Claude rewake explains the mid-turn gap: the rewake is bound to the current recovery generation and live session-lock owner, and no later watcher beacon or exhausted-failure marker supersedes it, because that session's turn-end will re-arm.
+A stale beacon is still healthy while `fm_autoarm_midturn_healthy` in `bin/fm-wake-lib.sh` proves a Claude rewake explains the mid-turn gap.
+That proof requires both of these:
+
+- The rewake is bound to the current recovery generation and live session-lock owner.
+- No later watcher beacon or exhausted-failure marker supersedes it.
+
+The tolerance holds because that session's turn-end will re-arm.
 Without that proof a stale or absent beacon is a genuine lapse and alarms.
-Under the extension model (Pi, pi-signed, and omp) a live identity-matched watcher is the ordinary healthy state, but a genuinely unheld lock with a beacon fresh within grace is also healthy while a live Pi or omp session provably owns continuity, because `.pi/extensions/fm-primary-pi-watch.ts` and `.omp/extensions/fm-primary-omp-watch.ts` tear the watcher down on every actionable wake and spawn the replacement themselves.
-A lock is genuinely unheld only when the lock directory or its symlinked owner directory is absent, or when the existing lock records no pid at all.
+
+#### Extension model
+
+Under the extension model (Pi, pi-signed, and omp) a live identity-matched watcher is the ordinary healthy state.
+A genuinely unheld lock with a beacon fresh within grace is also healthy while a live Pi or omp session provably owns continuity.
+That hand-off is benign because `.pi/extensions/fm-primary-pi-watch.ts` and `.omp/extensions/fm-primary-omp-watch.ts` tear the watcher down on every actionable wake and spawn the replacement themselves.
+
+A lock is genuinely unheld only in one of these cases:
+
+- The lock directory or its symlinked owner directory is absent.
+- The existing lock records no pid at all.
+
 Any lock with a recorded pid remains down when its pid, home, watcher path, or process identity fails the strict watcher health check.
-That ownership proof is `fm_extension_owns_supervision` in `bin/fm-wake-lib.sh`, which accepts either the Pi pair (`fm_pi_extension_owns_supervision`) or the omp pair (`fm_omp_extension_owns_supervision`): both primary extensions of one family must be recorded in their state markers at their current on-disk builds by the process named in `state/.lock`, and that process must still be alive; Pi's watcher marker must additionally name an active generation rather than a retiring handoff, while omp never inherits the Pi tolerance because its proof is keyed on its own two files and markers.
+
+That ownership proof is `fm_extension_owns_supervision` in `bin/fm-wake-lib.sh`.
+It accepts either the Pi pair (`fm_pi_extension_owns_supervision`) or the omp pair (`fm_omp_extension_owns_supervision`).
+The proof requires all of these:
+
+- Both primary extensions of one family must be recorded in their state markers at their current on-disk builds by the process named in `state/.lock`.
+- That process must still be alive.
+- Pi's watcher marker must additionally name an active generation rather than a retiring handoff.
+
+omp never inherits the Pi tolerance because its proof is keyed on its own two files and markers.
 Requiring the turn-end guard extension as well as the watch extension is deliberate, because a home without that structural backstop has no benign hand-off to tolerate.
-Without that proof an unheld lock alarms exactly as it did before, so an unloaded, version-drifted, or exited Pi or omp session is loud immediately, and a cycle the extension never restores is loud once the beacon passes grace.
+
+Without that proof an unheld lock alarms exactly as it did before.
+An unloaded, version-drifted, or exited Pi or omp session is therefore loud immediately.
+A cycle the extension never restores is loud once the beacon passes grace.
+
+#### Persistent-watcher harnesses
+
 Under every persistent-watcher harness a live identity-matched watcher with a fresh beacon is still required, so the pull guard keeps the same strict semantics there.
-Its banner names the true failing condition, either a missing live watcher process or a genuinely stale beacon with its real age, and keys the once-per-episode dedup on that condition rather than the beacon mtime.
-
-While `state/.afk` exists the daemon (`bin/fm-supervise-daemon.sh`) owns supervision and runs the watcher one-shot, in either away or quiet mode: the watcher exits on every wake and the daemon starts its replacement, so a turn boundary regularly lands in a hand-off where no watcher process holds the lock and nothing is wrong.
-The turn-end guard therefore accepts `fm_afk_daemon_owns_supervision` from `bin/fm-wake-lib.sh` as proof of supervision on that path: `state/.afk` must exist (the predicate does not distinguish away from quiet mode), and this home's `state/.supervise-daemon.lock` must name a live pid whose current process identity still matches the identity the daemon recorded for itself.
-That is the same identity discipline the watcher lock uses, so a recycled pid, a lock left behind by a killed daemon, and a daemon that never recorded its identity all fail it.
-A daemon that cannot record its own identity at startup logs a warning and keeps running, because a supervisor must not refuse to run over an unreadable `ps`; that warning is what names the cause when the guard then keeps blocking away/quiet-mode turn boundaries for the rest of that daemon's life.
-The proof covers ownership only, never freshness: the guard still requires a fresh beacon, so a daemon that stops restarting its watcher still blocks once the beacon passes grace, and a home with no daemon and no watcher blocks exactly as it did before.
-That beacon check uses the poll-derived grace described below rather than the flat `FM_GUARD_GRACE` default, because the daemon starts a fresh one-shot watcher only after it finishes handling the previous wake, and that handling can legitimately outrun a fixed 300-second window under load (a slow registered check, a busy supervisor pane) with the daemon perfectly healthy throughout.
+Its banner names the true failing condition, either a missing live watcher process or a genuinely stale beacon with its real age.
+It keys the once-per-episode dedup on that condition rather than the beacon mtime.
+
+### Away and quiet mode daemon ownership
+
+While `state/.afk` exists the daemon (`bin/fm-supervise-daemon.sh`) owns supervision and runs the watcher one-shot, in either away or quiet mode.
+The watcher exits on every wake and the daemon starts its replacement.
+A turn boundary therefore regularly lands in a hand-off where no watcher process holds the lock and nothing is wrong.
+
+The turn-end guard therefore accepts `fm_afk_daemon_owns_supervision` from `bin/fm-wake-lib.sh` as proof of supervision on that path.
+The proof requires both of these:
+
+- `state/.afk` must exist; the predicate does not distinguish away from quiet mode.
+- This home's `state/.supervise-daemon.lock` must name a live pid whose current process identity still matches the identity the daemon recorded for itself.
+
+That is the same identity discipline the watcher lock uses.
+A recycled pid, a lock left behind by a killed daemon, and a daemon that never recorded its identity all fail it.
+
+A daemon that cannot record its own identity at startup logs a warning and keeps running, because a supervisor must not refuse to run over an unreadable `ps`.
+That warning is what names the cause when the guard then keeps blocking away/quiet-mode turn boundaries for the rest of that daemon's life.
+
+The proof covers ownership only, never freshness.
+The guard still requires a fresh beacon, with these results:
+
+- A daemon that stops restarting its watcher still blocks once the beacon passes grace.
+- A home with no daemon and no watcher blocks exactly as it did before.
+
+That beacon check uses the poll-derived grace described below rather than the flat `FM_GUARD_GRACE` default.
+It uses that grace because the daemon starts a fresh one-shot watcher only after it finishes handling the previous wake.
+That handling can legitimately outrun a fixed 300-second window under load (a slow registered check, a busy supervisor pane) with the daemon perfectly healthy throughout.
+
 With `state/.afk` absent the daemon lock proves nothing and the strict watcher predicate is unchanged.
 
-`FM_STATE_OVERRIDE` wins over `FM_HOME/state`, and `FM_HOME` wins over repository-root `state/`.
-`FM_GUARD_GRACE` controls beacon freshness and defaults to 300 seconds.
-If `jq` is missing or hook stdin is empty, the guard exits 0 because it cannot safely read loop-guard fields.

+- `FM_STATE_OVERRIDE` wins over `FM_HOME/state`, and `FM_HOME` wins over repository-root `state/`.
+- `FM_GUARD_GRACE` controls beacon freshness and defaults to 300 seconds.
+- If `jq` is missing or hook stdin is empty, the guard exits 0 because it cannot safely read loop-guard fields.
 
 ### Guard grace and the poll cadence
 
-`bin/fm-watch.sh` touches `state/.last-watcher-beat` once per cycle, immediately before its terminal wait (`event_wait_or_sleep`) as well as at the top of the next cycle, so a healthy watcher's beacon can legitimately age up to `FM_POLL` seconds between touches.
-A fixed 300-second grace default stops correctly bounding staleness once a home's `FM_POLL` reaches or exceeds it: a perfectly healthy watcher mid-wait would then read stale at the edge of every full poll cycle by definition, which is exactly what a long-poll home (`FM_POLL=300`) hit against the Claude Stop-hook auto-arm (`bin/fm-claude-stop-autoarm.sh`).
-That hook and `bin/fm-watch.sh`'s own pre-acquisition staleness check (the "lock held by live pid but heartbeat is stale" refusal) both derive their default grace from the configured poll instead of a bare constant: `max(300, FM_POLL + 60)`, so the default never drops below the historical 300-second floor for the common short-poll case but grows with the poll cadence once that cadence would otherwise outrun it.

 `fm_poll_derived_grace` in `bin/fm-wake-lib.sh` is the single owner of that formula.
-That refusal has a ceiling: once the live holder's beacon is stale past `FM_WATCHER_STALL_BOUND` (default three times the grace), the re-arm re-verifies the holder against the lock's recorded identity, retires it with TERM, and starts in its place, so a watcher wedged mid-cycle can no longer refuse every replacement indefinitely; `bin/fm-watch.sh`'s header owns the exact wording and the survives-TERM fallback.
-The auto-arm hook additionally exports its resolved `FM_GUARD_GRACE` when it forks `bin/fm-watch-arm.sh`, so the arm wrapper and the watcher it may start judge staleness with the exact same value the hook just judged it with, whether that value came from an operator override or the poll-derived default.
-`bin/fm-turnend-guard.sh`'s daemon-ownership branch (`fm_afk_daemon_owns_supervision`, above, covering both away and quiet mode) also derives its beacon grace from `fm_poll_derived_grace` rather than falling back to the bare 300-second default, for the same reason: the daemon's watcher-restart cadence there is not a fixed poll loop, so a flat grace misreads a daemon that is genuinely still cycling as down.
-Every other direct `FM_GUARD_GRACE` reader (`bin/fm-guard.sh`, the strict-watcher checks in `bin/fm-turnend-guard.sh` and its harness-specific wrappers, `bin/fm-wake-lib.sh`) still falls back to the bare 300-second default unless `FM_GUARD_GRACE` is set explicitly in the environment.

 ## Harness integrations
 
+Each enabled primary harness adapts its own turn-end mechanism to the shared guard.
+
+| Harness | Turn-end hook | How it enforces the guard |
+| --- | --- | --- |
+| Claude | Two `Stop` hooks in `.claude/settings.json` | Blocks with exit status 2, cooperating with the Stop auto-arm |
+| Codex | `Stop` hook in `.codex/hooks.json` | Blocks with exit status 2 |
+| OpenCode | `session.idle` in `.opencode/plugins/fm-primary-turnend-guard.js` | Passive callback that schedules one follow-up |
+| Pi | `agent_settled` in `.pi/extensions/fm-primary-turnend-guard.ts` | Passive callback that schedules one follow-up |
+| omp | `session_stop` in `.omp/extensions/fm-primary-turnend-guard.ts` | Blocking hook that compels one continuation |
+| Cursor | `stop` hook in `.cursor/hooks.json` | Cannot block, so it parks and returns at most one follow-up |
+| Grok | `Stop` hook in `.grok/hooks/fm-primary-turnend-guard.json` | Native blocking, or one legacy `grok --resume` fallback |
+
+The registrations in detail:
+
 - Claude registers two `Stop` hooks in `.claude/settings.json`, both anchored through `CLAUDE_PROJECT_DIR`: `bin/fm-turnend-guard.sh --claude`, and `bin/fm-claude-stop-autoarm.sh` with `asyncRewake: true` and `timeout: 28800`.
 - Codex registers a `Stop` hook in `.codex/hooks.json`, anchors the executable to the hook process working directory, verifies a Firstmate-shaped hook-bearing root, and passes the original payload to the shared guard.
 - OpenCode listens for `session.idle` in `.opencode/plugins/fm-primary-turnend-guard.js`, lets the watcher coordinator act first, and calls `client.session.promptAsync` once when the guard returns 2.
 - Pi listens for `agent_settled` in `.pi/extensions/fm-primary-turnend-guard.ts`, runs once per logical agent run, and calls `pi.sendUserMessage(..., { deliverAs: "followUp" })` once when the guard returns 2.
-- omp answers its blocking `session_stop` hook in `.omp/extensions/fm-primary-turnend-guard.ts`, passing the payload's own `stop_hook_active` to the shared guard and returning `{ continue: true, additionalContext }` when the guard returns 2, so the continuation is compelled rather than requested; the continuation's stop carries `stop_hook_active: true`, which bounds it to one per turn, and omp's own cap of eight consecutive continuations is the second backstop. `session_stop` never fires for an interrupted turn or a task session, so those boundaries are deliberately unguarded.
+- omp answers its blocking `session_stop` hook in `.omp/extensions/fm-primary-turnend-guard.ts`, passing the payload's own `stop_hook_active` to the shared guard.

 - Cursor registers a `stop` hook in `.cursor/hooks.json` and delegates the whole turn boundary to `bin/fm-turnend-guard-cursor.sh`, the park described below.
   Cursor also loads `<project>/.claude/settings.json`, so every tracked Claude-shaped entrypoint whose event Cursor covers stands down on a Cursor-delivered payload through `bin/fm-hook-host-lib.sh`.
-  That predicate reads the delivered payload's own `cursor_version`, never the environment: Cursor exports `CURSOR_INVOKED_AS`, `CURSOR_PROJECT_DIR`, and `CURSOR_VERSION` into every child process, so an environment guard would also disable the hooks of a Claude session started by hand from a Cursor pane, which is the hazard the `GROK_SESSION_ID` exclusion below records.

   The guarded set is the `SessionStart` entry, the two `PreToolUse` Bash entries, and both `Stop` entries.
-  Cursor 2026.08.11-e8db854 does not fire the Claude-shaped `Stop` entry at all, but it is guarded anyway because Cursor has no `asyncRewake`: if a later build did fire it, `bin/fm-claude-stop-autoarm.sh` would run synchronously inside Cursor's stop step and hold that turn open for its declared multi-hour timeout, exactly the wedge grok 1.0.0 produced.

 - Grok registers a `Stop` hook in `.grok/hooks/fm-primary-turnend-guard.json` and delegates capability selection to `bin/fm-turnend-guard-grok.sh`.
   The tracked Claude Stop entries are inert when `GROK_AGENT` or `GROK_HOOK_EVENT` is present, so Grok's Claude-compatible settings loading cannot create a second continuation path.
-  Both markers are required because Grok does not inject the same variables into every process kind: grok 0.2.73 set `GROK_AGENT` for child and tool processes, while grok 1.0.0 hook processes carry `GROK_HOOK_EVENT`, `GROK_HOOK_NAME`, `GROK_SESSION_ID`, and `GROK_WORKSPACE_ROOT` but no `GROK_AGENT`.
-  A guard keyed on `GROK_AGENT` alone therefore stopped firing on grok 1.0.0, and the resulting Claude-only auto-arm ran synchronously under Grok - Grok has no `asyncRewake`, so it waited on the foregrounded watcher for the declared 28800-second timeout and the Grok turn never ended.

   Do NOT widen this guard to `GROK_SESSION_ID`: Grok injects that into every child process, so it can survive into a Claude session that Grok launched and would silently disable Claude's own continuity.
-  The same marker guard carries every tracked `.claude/settings.json` entry whose event Grok already covers through its own `.grok/hooks/` registration, which is both `Stop` entries, the `SessionStart` entry, and the two `PreToolUse` Bash entries; `bin/fm-subagent-pretool-check.sh` is the one deliberate unguarded exception because no Grok registration covers the subagent-spawn event, recorded in [`subagent-guard.md`](subagent-guard.md) "Known residual gap".

 - pi-code, Pi's Claude-hook compatibility extension, also loads `<project>/.claude/settings.json` and has no `asyncRewake`, so it awaits every Stop hook it delivers.
-  `bin/fm-claude-stop-autoarm.sh` therefore stands down on a pi-code-delivered payload, or its foreground arm would run synchronously and hold Pi's turn open for the declared multi-hour timeout, exactly the wedge Cursor and grok 1.0.0 would produce (issue #3343); Pi's own native extensions own its supervision.
-  The discriminator is the payload's own `transcript_path`, not the environment and not the shared foreign-host predicate above: pi-code stamps it with Pi's session file under `/.pi/`, a path component a Claude transcript never carries.

+### Claude and Codex blocking
+
 Claude and Codex can block a Stop directly with exit status 2 and stderr.
 Both payloads carry `stop_hook_active`.
 In the default Codex mode, a true value lets the second stop finish after one forced continuation.
 
+### Claude cooperative mode
+
 Claude runs the guard with `--claude`, which ignores `stop_hook_active` and cooperates with the Stop-owned auto-arm.
-Before the Claude cooperative budget can re-block a Stop, the guard checks for a live foreign session-lock owner and takes the same safe diagnostic exit described under "Guard predicates".
-Claude Code sets `stop_hook_active=true` on every stop after any stop-hook continuation, including `asyncRewake` rewakes, which re-opened the 2026-07-21 blind window under the default one-shot behavior.
-The Claude mode waits up to `FM_CLAUDE_AUTOARM_SYNC_WAIT_MS` (default 800 milliseconds) and allows the stop when the watcher is healthy, the auto-arm's generation claim is open, or `state/.claude-autoarm-epoch` contains a fresh actionable rewake owned by this event epoch.
-The claim is the ledger entry itself: the epoch sequence in `state/.claude-autoarm-epoch` is a monotonic claim generation, line 1 records the claim and terminal outcome, and line 2 records the claiming process's mandatory pid-identity; `fm_autoarm_claim_open` and `fm_autoarm_claim_next` in `bin/fm-wake-lib.sh` own the format contract.
-A claim is open while its outcome is `arming`, its owner pid is alive, its recorded identity successfully recomputes and matches that pid, and it is not stuck - stuck meaning the entry and the watcher beacon are both older than the guard grace, which proves the owner hung mid-arm (a healthy hours-long foregrounded cycle keeps the beacon beating, and every arming phase with no watcher is bounded in seconds).
-Anything else - a finished outcome, a dead or identity-mismatched owner, a stuck owner, an identityless entry, or no entry - lets the next Stop-owned firing take the next generation and arm; taking a newer generation is the reclaim, and a steady-state predecessor is never signalled or revoked.
-No mutex is held across arming or output: `state/.claude-autoarm.lock` survives only as a micro-mutex serializing individual ledger writes, and a superseded owner goes completely silent - ownership is re-verified before every arm invocation, episode-state mutation, ledger write, and continuation.
-The irrevocable commit point of a translation is the exit status, because the harness delivers the collected stderr banner only on exit 2, so an owned terminal commit decides the exit: markerless outcomes commit with the ledger write, while the once-per-episode failure notice commits only when its marker is created after the winning failed write in the same critical section.
-A generation whose required marker cannot be created is refused and exits 0 silently even after printing; its terminal ledger entry is superseded by a later firing, which retries the notice.
-Without those boundaries a cycle that armed, delivered one rewake, and exited left both Stop participants deferring to its leftover lock indefinitely (2026-08-14: two tasks in flight, a beacon 40 minutes cold, every turn blind until an operator intervened), and a hook that hung mid-arm kept a live pid on the lock so the watcher was never auto-re-armed again (2026-08-26).
-Two bounded residuals are accepted intent, each costing at most one extra continuation turn absorbed by the durable idempotent wake queue: an owner that dies between its owned terminal write and its own process exit, and a hung old-build owner that resumes during the one legacy upgrade window.
-A legacy build's lock-holding claim (recognizable by its `autoarm` role file) still defers or reclaims under the legacy abandonment proof, with a live identity-verified stuck owner retired via TERM before its lock is removed and an unverified pid never signalled, so an upgrade mid-session can neither double-arm nor deadlock, and a failed reclaim re-blocks rather than allowing a blind stop.
+Claude Code sets `stop_hook_active=true` on every stop after any stop-hook continuation, including `asyncRewake` rewakes.
+Under the default one-shot behavior, that re-opened the 2026-07-21 blind window.
+
+Before the Claude cooperative budget can re-block a Stop, the guard checks for a live foreign session-lock owner and takes the same safe diagnostic exit described under "Guard predicates" ([foreign session-lock owner](#foreign-session-lock-owner)).
+
+The Claude mode waits up to `FM_CLAUDE_AUTOARM_SYNC_WAIT_MS` (default 800 milliseconds).
+It allows the stop when any of these holds:
+
+- The watcher is healthy.
+- The auto-arm's generation claim is open.
+- `state/.claude-autoarm-epoch` contains a fresh actionable rewake owned by this event epoch.
+
+#### Auto-arm generation claim
+
+The claim is the ledger entry itself.
+The ledger is `state/.claude-autoarm-epoch`:
+
+- Its epoch sequence is a monotonic claim generation.
+- Line 1 records the claim and terminal outcome.
+- Line 2 records the claiming process's mandatory pid-identity.
+
+`fm_autoarm_claim_open` and `fm_autoarm_claim_next` in `bin/fm-wake-lib.sh` own the format contract.
+
+A claim is open while all of these hold:
+
+- Its outcome is `arming`.
+- Its owner pid is alive.
+- Its recorded identity successfully recomputes and matches that pid.
+- It is not stuck.
+
+Stuck means the entry and the watcher beacon are both older than the guard grace, which proves the owner hung mid-arm.
+A healthy hours-long foregrounded cycle keeps the beacon beating, and every arming phase with no watcher is bounded in seconds.
+
+Anything else lets the next Stop-owned firing take the next generation and arm.
+That covers a finished outcome, a dead or identity-mismatched owner, a stuck owner, an identityless entry, or no entry.
+Taking a newer generation is the reclaim, and a steady-state predecessor is never signalled or revoked.
+
+No mutex is held across arming or output.
+`state/.claude-autoarm.lock` survives only as a micro-mutex serializing individual ledger writes.
+A superseded owner goes completely silent.
+Ownership is re-verified before every arm invocation, episode-state mutation, ledger write, and continuation.
+
+#### Exit status as the commit point
+
+The irrevocable commit point of a translation is the exit status, because the harness delivers the collected stderr banner only on exit 2.
+An owned terminal commit therefore decides the exit:
+
+- Markerless outcomes commit with the ledger write.
+- The once-per-episode failure notice commits only when its marker is created after the winning failed write in the same critical section.
+
+A generation whose required marker cannot be created is refused and exits 0 silently even after printing.
+Its terminal ledger entry is superseded by a later firing, which retries the notice.
+
+#### Why the claim boundaries exist
+
+Without those boundaries, two failures occurred:
+
+- A cycle that armed, delivered one rewake, and exited left both Stop participants deferring to its leftover lock indefinitely.
+  On 2026-08-14 two tasks were in flight, a beacon was 40 minutes cold, and every turn was blind until an operator intervened.
+- A hook that hung mid-arm kept a live pid on the lock, so the watcher was never auto-re-armed again (2026-08-26).
+
+Two bounded residuals are accepted intent, each costing at most one extra continuation turn absorbed by the durable idempotent wake queue:
+
+- An owner that dies between its owned terminal write and its own process exit.
+- A hung old-build owner that resumes during the one legacy upgrade window.
+
+A legacy build's lock-holding claim (recognizable by its `autoarm` role file) still defers or reclaims under the legacy abandonment proof.
+A live identity-verified stuck legacy owner is retired via TERM before its lock is removed, and an unverified pid is never signalled.
+An upgrade mid-session can therefore neither double-arm nor deadlock, and a failed reclaim re-blocks rather than allowing a blind stop.
+
+#### Failure progression and block budget
+
 Fresh `failed` and `failed-suppressed` outcomes enter or advance the failure progression instead of acting as unconditional recovery proof.
 The auto-arm itself rechecks the healthy watcher predicate and retries a bounded number of times before reporting a genuine failure.
-The foreground arm legitimately follows a healthy watcher until its next wake, so the hook catches HUP, TERM, and INT from host timeout or teardown and commits the ordinary durable failed outcome and failure-notice marker before exiting 2 for a recovery turn.
+
+The foreground arm legitimately follows a healthy watcher until its next wake.
+The hook therefore catches HUP, TERM, and INT from host timeout or teardown and commits the ordinary durable failed outcome and failure-notice marker before exiting 2 for a recovery turn.
 Claude drops that exit 2 when it terminated the hook at the configured timeout itself, so a park that outlives the timeout ends without a rewake (`bin/fm-claude-stop-autoarm.sh` header).
-The first fresh exhausted-failure epoch preserves its handoff without consuming a blocked-stop count, while later fresh failed epochs advance the same monotonic progression instead of resetting it.
-When none of those proofs appears, it re-blocks up to `FM_CLAUDE_TURNEND_BLOCK_BUDGET` times (default 3, below Claude's 8-block override).
+
+The first fresh exhausted-failure epoch preserves its handoff without consuming a blocked-stop count.
+Later fresh failed epochs advance the same monotonic progression instead of resetting it.
+When none of those proofs appears, the guard re-blocks up to `FM_CLAUDE_TURNEND_BLOCK_BUDGET` times (default 3, below Claude's 8-block override).
 In Claude mode, positive watcher recovery clears the block budget, failure notice, and attended alarm together under the existing budget lock before either hook reports ordinary recovery.
-The one loud attended fail-open is available only when the auto-arm has recorded an exhausted failure, its one notice is already consumed, the block budget is exhausted, and a final check finds neither a healthy watcher nor an automatic continuation.
-Each epoch identity is charged at most once per Stop under the budget lock, and a re-block against an epoch the auto-arm did not advance past the previous re-block is charged as well.
+
+The block budget is charged by two rules:
+
+- Each epoch identity is charged at most once per Stop under the budget lock.
+- A re-block against an epoch the auto-arm did not advance past the previous re-block is charged as well.
+
 That second rule still bounds an inert auto-arm when a hook never fires or fails before its generation claim and therefore leaves the ledger frozen at its last outcome.
+Charging only epoch changes let the count freeze with that ledger, so the remaining inert-hook cases could re-block without limit and make the attended fail-open unreachable.
+`budget_account_current_epoch` in `bin/fm-turnend-guard.sh` owns the rule.
 A verified live foreign session-lock owner takes the earlier diagnostic safe exit instead and never reaches this budget path.
-Charging only epoch changes let the count freeze with that ledger, so the remaining inert-hook cases could re-block without limit and make the attended fail-open unreachable; `budget_account_current_epoch` in `bin/fm-turnend-guard.sh` owns the rule.
 Whenever both coordination locks are needed, positive auto-arm recovery and the terminal check acquire the auto-arm owner lock before the budget lock.
+
+#### Attended fail-open
+
+The one loud attended fail-open is available only when all of these hold:
+
+- The auto-arm has recorded an exhausted failure.
+- Its one notice is already consumed.
+- The block budget is exhausted.
+- A final check finds neither a healthy watcher nor an automatic continuation.
+
 After that alarm, the Stop auto-arm suppresses further exit-2 continuations until positive watcher recovery, so the final fail-open remains reachable.
 The alarm cannot repeat during that failure episode, and a later unhealthy stop blocks again.
 A positively verified healthy watcher clears the failure notice, alarm, and block budget for a future independent episode.
 A Claude failure notice describes the automatic mechanism as broken and does not direct a routine manual background arm.
 
+### Passive adapters
+
 OpenCode, Pi, and pi-signed expose passive callbacks for this purpose.
-Their adapters fail open at the hook boundary to protect the user session but schedule one bounded follow-up when the predicate blocks.
+Their adapters fail open at the hook boundary to protect the user session.
+When the predicate blocks, they schedule one bounded follow-up.
 omp is the exception among the Pi-derived harnesses: its `session_stop` hook blocks like Codex's `Stop` hook, so no passive latch is needed and the `stop_hook_active` loop guard applies unchanged.
+
 The generated prompts use the canonical `turn-end-guard` kind after the U+2063 `FIRSTMATE_OP: ` prefix, so Ahoy does not treat them as captain messages.
-Each passive adapter owns a loop latch.
-Pi keeps the latch across internal tool turns and clears it only when the generated follow-up settles or delivery fails.
-OpenCode's forced follow-up is supported for persistent TUI sessions and remains fail-open in headless `opencode run`.

+
+### Grok capability selection
+
+Grok makes exactly one typed capability decision from each running Stop payload:
+
+- A boolean `stopHookActive` selects native blocking, including both false on the initial stop and true on the bounded continuation.
+- The camel-case field has precedence when both spellings appear.
+- When it is absent, a boolean `stop_hook_active` selects the same native path for compatibility.
+- When both capability spellings are absent, the adapter preserves one pre-native `grok --resume` fallback guarded by `GROK_TURNEND_GUARD_ACTIVE` and intentionally omits `--permission-mode`.
+- Malformed JSON, a selected field with a non-boolean type, missing `jq`, missing hook prerequisites, or an already-active legacy guard allows the stop without starting either continuation path.

-Cursor cannot block a turn end at all: its blocked-response mapper returns an empty object for the `stop` step, so exit 2 is a silent no-op, verified both statically and live.

+Every path exits 0, and its only channel is at most one `followup_message` on stdout.
 Cursor runs that hook synchronously and awaits it, so one script owns both halves of the boundary.
-While supervision is needed it PARKS: it runs `bin/fm-watch-arm.sh` as its own tracked child, holds the boundary open until the watcher closes, and returns an actionable close as one `watcher`-kind follow-up, spending no model tokens while parked.
+
+While supervision is needed it PARKS:
+
+1. It runs `bin/fm-watch-arm.sh` as its own tracked child.
+2. It holds the boundary open until the watcher closes.
+3. It returns an actionable close as one `watcher`-kind follow-up.
+
+It spends no model tokens while parked.
 This is the same between-turns shape as Claude's Stop auto-arm, so `fm_supervision_model` classifies Cursor as `autoarm` and the mid-turn pull guard accepts a fresh beacon without a live watcher.
+
+#### Cursor park under a Pi host
+
 The park stands down without arming when `PI_CODING_AGENT=true` and neither `CURSOR_AGENT` nor `CURSOR_INVOKED_AS` is set.
-Pi-with-Cursor-provider sessions (pi-cursor-sdk) load project `.cursor/hooks.json` into the Pi process, and a Cursor park there would race Pi's extension-owned `fm_watch_arm_pi` continuity, resurface rearm wakes, and abort in-flight asks.
-`fm-spawn`'s cursor launch clears `PI_CODING_AGENT`; a hand-started cursor-agent may still inherit it.

 When either Cursor identity marker is present, the park still runs despite a leaked `PI_CODING_AGENT`.
-When the park cannot establish a cycle it asks this shared guard with `--cursor` and renders a returned exit 2 as one bounded `turn-end-guard` follow-up, capped by `FM_CURSOR_TURNEND_BLOCK_BUDGET` (default 3) consecutive unproductive nags per session; a delivered wake resets that budget because it is productive work.
-The follow-up loop is bounded TWICE, because either bound alone is insufficient.
-`loop_limit` in `.cursor/hooks.json` is Cursor's own ceiling and the only one that still holds if the adapter is broken or replaced: once `loop_count` reaches it Cursor stops invoking the hook, verified live.
-`FM_CURSOR_TURNEND_LOOP_CEILING` (default 180) bounds the payload's `loop_count` from inside and sits deliberately BELOW the registered `loop_limit`, so firstmate's bound bites first and emits one final loud notice instead of supervision going silently dark at Cursor's ceiling.
-`loop_count` is Cursor's richer analogue of `stop_hook_active`: verified live as 0 on the first stop after a real user message, +1 per follow-up-driven stop, and reset to 0 by the next real user message.

+- The next real user message resets it to 0.
+
+### Captain messages during a Cursor park
 
 A captain message typed while the hook is parked is accepted and runs its turn immediately, and Cursor does NOT terminate the parked hook.
-The older park remains the recorded owner until that captain turn ends and the next `stop` hook claims the baton, so an actionable watcher close in that window can still be delivered by the older park as one follow-up.
-That delivery is bounded and safe: only one park exists before the next `stop` claim, so it is a real wake and never a stale duplicate of another park's wake, while the durable wake queue makes handling idempotent.

 Each invocation publishes its sequence in `state/.cursor-park-owner` under the short publication and commit lock `state/.cursor-park-owner.lock`.
-The same bounded critical section covers the final owner and away-mode checks, follow-up output, and repair-budget commit, so the next `stop` claim makes an older park that is still running stand down without emitting or changing shared state.

+The next `stop` claim therefore makes an older park that is still running stand down without emitting or changing shared state.
 The lock is never held while the arm is sleeping, while the hook is polling, or while output is prepared.
-The park revalidates session ownership while polling and again inside the final commit section, but it deliberately does not hold the fleet session lock across output because an awaited hook must not block home-wide session acquisition; the remaining microsecond takeover window can produce at most one harmless wake that drains the durable queue.

+
 Cursor's `beforeSubmitPrompt` step fires once on a real captain message and does not fire for hook-driven follow-ups, so invalidating the park baton there would close the pre-claim window exactly.
 The step is now registered only for the [dialog mirror](supervision-host.md#the-dialog-mirror); it does not invalidate the park baton.
 Baton invalidation and the `preCompact` surface remain deferred.
 
+### Adapter failures in the pull guard

 If a passive adapter cannot invoke its SDK, or the Grok legacy fallback cannot find `grok` or a session id, the next pull-based `fm-guard.sh` call reports the problem.
 That warning uses `bin/fm-supervision-instructions.sh --repair-line`, so it always points to the active harness protocol rather than embedding another repair command.

Subject: [PATCH 61/84] docs: move situational AGENTS.md sections into
 on-demand skills (#5872)

* docs: move situational AGENTS.md sections into on-demand skills

Backpass memory optimization: shrink the always-loaded AGENTS.md by moving
situational contracts (home layout, session-start recovery, validation and
landing supervision, scout completion, away/quiet supervision, Relay
ownership) into agent-only skills loaded at their triggers, with a trigger
index skill.

* docs: classify the new on-demand skills' documentation audience

Register the seven new agent-only skills as agent-runtime docs and fix a
link in validation-supervision that kept its AGENTS.md-relative path.

* docs: close load-timing gaps found by the live regression check

- load validation-supervision whenever an ask-user finding is decided or
  answered, so forbid --yes and process-every-return reach the worker
- keep the mid-task captain-ask rule, the unconfirmed network-checks rule,
  and the worker account pin rule inline in AGENTS.md
- fix cross-references that still pointed at moved AGENTS.md sections

+# Away and quiet supervision safety
+
+The `/afk` and `/quiet` skills each own their daemon procedure, which is otherwise identical; these safety facts apply to both:
+
+- Every current daemon injection uses the `away-supervisor` kind from `bin/fm-operational-input.sh` after `FM_OPERATIONAL_PREFIX` (U+2063 INVISIBLE SEPARATOR followed by `FIRSTMATE_OP: `), except that a Claude Code primary, which strips U+2063, receives that owner's record-backed doorbell and it counts as marked only when `bin/fm-operational-input.sh open <path>` verifies its record; the `/afk` skill owns legacy bare-marker compatibility.
+- `state/.afk-contract` is the away posture, written in the same turn as `/afk` before any other work, because `/afk` is itself the go: no read-back gates entry or waits for a go; entry announces hold-for-return only, and the away session acts on those words by its own judgment through the guarded scripts under standing authority, holding for the return on doubt.
+- While `state/.afk` exists, the daemon owns supervision; do not arm a separate watcher.
+  The daemon is never launched on Pi, where the ordinary supervision session continues under the record with main parked: the branch takes every safe actionable wake it can, and only a declined wake (including a broken branch or unsafe scan) or a watcher failure wakes main.
+  Away mode on a non-Pi home with `config/supervision-host` works the same way with the supervision host as the branch; a wake it hands back arrives through that harness's own wake path and is never the captain's return.
+- A marked message while away or quiet mode is active is internal escalation and does not exit that mode.
+- A message beginning `/afk` refreshes away mode; a message beginning `/quiet` refreshes quiet mode.
+- Any other unmarked message means the captain returned in away mode (load `/afk`, run the return owner, and do not process that message as ordinary work until its durable catch-up gate clears), or, in quiet mode, is simply answered as ordinary work with the flag and daemon left untouched until an explicit `/quiet off`.
+- Away and quiet mode never expand approval authority for merges, ask-user findings, destructive actions, irreversible actions, or security-sensitive choices.
+- Bias ambiguous input toward exit because a present captain takes precedence.

 Never close anything the captain owns without recording what he actually said: `bin/fm-captain-hold.sh answer` writes his exact words into the task and closes a question-shaped call, while `--release` frees a captain-gated work item to proceed.
 A merge approval uses that existing release path because approval permits the merge to proceed; cleanup closes the work only after it lands and records what shipped.
 Closing a held row at merge approval instead records completion before landing, so the backlog claims completion before the work actually ships.

+When the answer changes what a task must build, follow `AGENTS.md` section 7's mid-task ask rule to preserve the captain's words in the brief and steer the worker.
 When the captain says "later", that is an answer too: re-hold with `bin/fm-captain-hold.sh hold <id> --reason "<reason>" --until <date>` so the item leaves the live Captain's Call and resurfaces on its date, instead of leaving a live-looking card or fabricating a closure.
 "A keyed answer resolves its matching captain-held task" is one capability with one owner, `bin/fm-captain-hold.sh answers`, and every channel that carries a captain answer feeds it the same task id and answer; a channel never maps keys to tasks, records a decision, or resolves anything itself.
 Chat already feeds it through `bin/fm-send.sh --resolve-key`, and a captured-answer source feeds it once bound with `bin/fm-captain-hold.sh bind <source-id>`; bind before arming the source, and key each structured question by the held task's id.

+## Relay activation and ownership contract
+
+Relay is the public-mention integration older docs and some emitted lines still call "X mode"; its identifiers keep the `FMX_`, `x-`, and `fm-x-` spellings.
+Relay ships inert and causes no behavior change until the home opts in by placing `FMX_PAIRING_TOKEN` in its gitignored `.env`.
+That token is consent for public replies and normal reversible lifecycle actions from eligible mentions, not authority for destructive, irreversible, or security-sensitive action; those still require trusted-channel confirmation.
+`docs/configuration.md` owns activation, generated state, cadence, wire protocol, and opt-out mechanics.
+
+A Relay-only home still requires the live supervision cycle so mentions can wake it without fleet work.
+On an `x-mention <request_id>` or `x-mode-error ...` check wake, load `fmx-respond`, which owns classification, public-safety policy, reply or dismissal, task linking, and follow-ups.
+For every Relay-linked terminal outcome, load that owner and use the promised-final reconciliation when a typed public commitment exists, otherwise post the final completion follow-up before teardown.
+
+A promised final public reply is durable state, never conversation memory.
+Load `fmx-respond` before promising one, on a `public-followup ...` check wake, and whenever the session-start digest lists a public commitment awaiting delivery or an open public loop.
+Only the home holding the relay consent and thread binding ever posts it, so never ask a secondmate or crewmate to find the thread or send the reply, and never recover a terminal result by reading a `done:` sentence.

+# Scout outcome and promotion
+
+A completed scout must leave a self-contained report before its scratch worktree can be discarded; read and relay its findings, record the report as the Done artifact, and re-evaluate the queue.
+A report may recommend implementation but does not authorize it.
+Before treating the investigation or any visual review as complete, load `captain-hold-lifecycle`; teardown enforces that shared completion gate.
+When a scout's deliverable is a visual artifact the captain will iterate on, keep it alive and follow the crew-hosted Lavish board contract in `docs/configuration.md` rather than arming or polling the board from firstmate.
+When implementation is separately authorized, promote the existing scout through `bin/fm-promote.sh` rather than creating a duplicate task.
+The promoted worker must inventory scratch state, return to a clean default-branch base, carry over only intended fix changes, create the ship branch, and follow the project's selected delivery path while leaving scratch commits and debug edits behind and turning a reproduced bug into the regression test.

+user-invocable: false
+metadata:
+  internal: true
+---
+
+# Session-start recovery
+
+The digest itself makes no external-network call and never waits for one.
+Every network check a session start owes - GitHub auth, dead-secondmate relaunch, secondmate convergence, pending handoff delivery, and project clone refresh - runs off the digest's blocking path in a bounded worker owned by `bin/fm-startup-network.sh` and is reported in the digest's own `NETWORK CHECKS` section.
+The locked startup inactive-outcome scan joins that worker so a slow local current-state read cannot block the digest; its findings use the ordinary durable wake queue.
+
+1. **Lock** - acquires the per-home session lock first, before anything mutates shared state, then starts the deferred startup stage above.
+2. **Bootstrap** - detect-only checks (tool/version problems, the worktree-tangle check, harness override, dispatch-profile validation, backlog-backend status) always run, but routine confirmations stay silent by default.
+   When the lock could not be acquired, the worktree-tangle check uses read-only advisory wording without a checkout repair command.
+   Home-local stale Herdr projection cleanup and the six bootstrap MUTATING sweeps - same-home backlog reconciliation, fleet sync, secondmate convergence, secondmate liveness, pending remote handoff retry, and Relay artifact writes - run only when this session actually holds the lock from step 1; the four network ones among them run in the deferred stage rather than in this section.
+   The secondmate liveness sweep deterministically accounts for every registered secondmate: it relaunches only from the recovery-grade `dead` or `missing` states, preserves ambiguous, unreadable, or unreachable remote targets, and reports skipped or failed guarantees as `SECONDMATE_LIVENESS:` lines (`bin/fm-bootstrap.sh`; `bin/fm-backend.sh`'s `fm_backend_agent_state`; `docs/remote-secondmates.md`).
+   Ordinary supervision continues the same guarantee through the watcher's cadence-gated liveness tick over the shared `bin/fm-secondmate-liveness-lib.sh`, so a mate that dies mid-session is relaunched without waiting for the next session start.
+3. **Wake queue** - when locked, drains and presents the durable wake queue without running the inactive-outcome scan inline, and prints the raw records prominently as this turn's first work queue; a clearly labeled status-event annotation may follow a valid `signal` record and includes every status line still unread at the presentation cursor, but never replaces the raw record or current-state reconciliation, and a lapsed watcher chain still surfaces here via the same guard alarm.
+   Presented records remain durable until the handling turn runs the generation-bound acknowledgement printed by the drain.
+   Every locked drain also prints a bounded fleet-wide `OPEN DECISIONS` section when durable decision records remain open, including when the queue itself is empty; reconcile those entries before continuing.
+   A main drain may also print a bounded, one-shot `STATUS OUTCOME BACKSTOP` when a task's newest captain-facing status event has no covering supervision-branch outcome; handle it as a recovered wake even when no queue row remains.
+   The same drain prints every still-unread `note:` line and pending-reply resolution since the last presentation in an unbounded `UNREAD STATUS` section, so an answer buried under a later routine line is not dropped; those lines are not re-printed after that presentation.
+   It also prints a bounded `RECORD DIVERGENCE` section naming every captain call the status log reads as resolved while its backlog task is still held; nothing is closed for you, and `captain-hold-lifecycle` owns the reconciliation.
+   When the lock could not be acquired and verified, the queue is left untouched because no session mutation is authorized, and the guard's tangle/watcher-liveness alarms still print in read-only advisory mode without drain, supervision repair, or checkout repair commands.
+4. **Supervision operating instructions** - after the wake queue and before both digests, the digest emits exactly one operating block for the detected primary harness, followed by the read-once contract that governs them.
+   The script itself never starts supervision; the emitted harness protocol owns the exact wait or wake mechanism.
+5. **Fleet-state digest** - after that read-once contract and ahead of the context digest, the compact backlog listing owned by `bin/fm-session-start.sh`; every `state/<id>.meta`; a bounded tail of each task's `state/<id>.status` (labeled as wake-EVENT history, not current state, with the full log path printed for a deeper read); the away posture (`state/.afk-contract`, plus the `state/.afk` daemon flag where a daemon runs); and one cheap alive/dead read of each task's recorded backend endpoint.
+   That liveness line is a fast presence check only, not a full state read - when you need a crew's actual current state (a run-step, not just "is the pane there"), read it with `bin/fm-crew-state.sh <id>` as before; the digest deliberately skips that deeper, slower read for every task so it stays fast and bounded.
+6. **Network checks** - after the fleet-state digest, the deferred stage's result, or an explicit statement of what it has not confirmed yet.
+   A read-only session runs no network checks at all and says so.
+7. **Context digest and next step** - last of the bulk sections, the full contents of `data/projects.md`, `data/secondmates.md`, `data/captain.md`, `data/captain-shared.md`, and `data/learnings.md`, each clearly delimited, followed by the closing reminder.
+   A file that does not exist prints an explicit `ABSENT` marker, never confused with an empty-but-present file: absence is meaningful (`captain.md` absent means use the firstmate repo's built-in defaults, `projects.md` absent means rebuild it from the clones under `projects/`, etc.).
+   The closing reminder points back to the emitted supervision block and preserves only the lock, afk, Relay, and read-once reminders.
+
+Bootstrap detects first, asks for consent, and installs only after the captain approves in the current session.
+Do not dispatch until the essential launch tools are present and GitHub authentication is good; presentation availability follows `bootstrap-diagnostics` and does not block nonvisual work.
+Use `gh-axi` for GitHub, `chrome-devtools-axi` for browser work, and compatible `lavish-axi` for visual decisions or reports; consult current help rather than memorizing flags.
+A silent bootstrap section needs no action; for any printed actionable diagnostic line, load `bootstrap-diagnostics` and follow its owner procedure.
+`BOOTSTRAP_INFO:` lines are completed no-action facts and do not require loading a skill.
+`secondmate-provisioning` owns startup secondmate sync, liveness, and inherited local-material convergence.

+# Ship landing
+
+For PR-based ship tasks, the ready signal depends on mode: `no-mistakes` reports `done [at=<epoch>]: PR <url> checks green` after CI is green, while `direct-PR` reports `done [at=<epoch>]: PR <url>` after opening the PR, each only for a non-draft PR; a lane that deliberately holds a draft declares a wait instead, and `bin/fm-pr-check.sh` refuses to arm merge monitoring on a draft.
+Run `bin/fm-pr-check.sh <id> <PR url>` with the URL copied from that ready signal or the resolved checks-green `fm-crew-state.sh` line - it records `pr=` and the forge's `pr_head=` when available in the task's meta and arms the watcher's merge poll.
+`bin/fm-dod-lib.sh` owns the named-head gate on that ready signal: a ship `done:` whose named head exists only in the worker's disposable copy is not ready (`bin/fm-crew-state.sh` reports blocked, `bin/fm-pr-check.sh` refuses to register, and a secondmate does not publish that done upstream).
+That blocked reading is the gate working, not a stuck worker, so steer the worker on the commit the refusal names rather than waiting.
+A direct-PR worker pushes that commit to its PR branch, and a local-only worker commits it on its ship branch.
+A no-mistakes worker re-validates it with /no-mistakes so the pipeline stays the one publisher; it never pushes from its copy.
+In no-mistakes mode the earlier `done [at=<epoch>]: {summary}` is the pipeline handoff and is not gated.
+Tell the captain the PR's full `https://...` URL copied from the worker's ready line, the resolved checks-green crew-state line, or the task's `pr=` metadata, a concise outcome summary, and the no-mistakes risk level when applicable.
+A captain instruction to merge is explicit authority; `yolo` is the only standing routine merge authority.
+For any custom `state/<id>.check.sh` you write yourself, keep it an ordinary single-link mode-`0700` file, print one line only when firstmate should wake, print nothing otherwise, finish before `FM_CHECK_TIMEOUT`, then bind its current bytes with `bin/fm-check-register.sh <id>` before the watcher may execute it.
+Retire a custom check only through `bin/fm-check-unregister.sh <id>` (or `bin/fm-teardown.sh` for a spawned task); never hand-compose an `rm` with `$STATE`/`$ID`.
+
+Tear down a ship task only after landing is confirmed.
+A teardown refusal for uncommitted or unlanded work is a stop-and-investigate result, never an obstacle to bypass.
+Never force teardown without explicit discard authority.
+After successful teardown, record completion, retain only the configured recent Done history, and re-evaluate queued work whose blockers and time gates have cleared.
+
+A secondmate is persistent and an empty queue is healthy.
+Retire one only on an explicit captain or main-firstmate decision, after loading `secondmate-provisioning`; its home must contain no work under way, and forced discard still requires explicit captain authority.

+description: Load when a ship starts or already has an active no-mistakes validation run, including a mid-run requirement change or finding, and before deciding or answering any ask-user finding.
+user-invocable: false
+metadata:
+  internal: true
+---
+
+# Validation supervision
+
+For a no-mistakes ship, trigger validation on the same worker after its implementation commit, using the harness invocation owned by `harness-adapters`.
+The task worker that starts a no-mistakes run drives the pipeline and owns every `no-mistakes axi run` and `no-mistakes axi respond` call through the next gate or outcome.
+Firstmate never invokes `no-mistakes axi respond` for a crew-owned run.
+`bin/fm-dod-lib.sh` owns the worker-side `--intent` contract.
+Once validation starts, prefer routing new requirements to follow-up work rather than expanding the current task, unless a new requirement completely invalidates the work being validated; however, the smallest downstream changes needed to keep already accepted product or engineering behavior correct, add behavioral tests where an executable contract exists, or keep documentation accurate remain within the current task even when they touch files not named at intake, and corrections required to satisfy already accepted intent are not new requirements.
+
+Only a current, explicit captain instruction that completely invalidates the work being validated keeps the task with the same worker instead of routing it to follow-up work or handing it to a replacement.
+That worker cancels the active run through no-mistakes axi's supported abort command and confirms through axi status that the run has stopped before changing any code.
+The worker then follows `branch_sync.next_action` from structured axi status: use axi sync's supported guarded recovery only when its code is `recover_custody`, and otherwise proceed only when structured status confirms that branch ownership is already returned and no recovery is required.
+Custody recovery settles branch ownership, not content: the worker must replace the obsolete work from the correct pre-invalidation base rather than building on top of the recovered-but-obsolete head, keeping the obsolete run's own pipeline-fix commits out of what gets validated and shipped.
+Apart from that single supported abort, do not hand-edit, commit, restart, or start a second validation run while the obsolete run still owns the branch.
+Once ownership is settled, validate exactly once against that final head so no obsolete or intermediate head is ever treated as authoritative.
+
+An ask-user finding returns as `needs-decision`; firstmate loads `ask-user-authority` and either decides or escalates per that skill.
+Send the same worker one exact decision naming the decision key, step, action, affected finding IDs, instructions where needed, and exact response command, passing `--resolve-key` so the worker's open decision record closes at answer time.
+Require the matching `resolved` event, forbid `--yes`, and require the worker to process every synchronous return until completion or a genuinely new escalation.
+Resume fleet supervision immediately after the decision lands.
+
+Judge validation by the resolved state line from [`bin/fm-crew-state.sh`](../../../bin/fm-crew-state.sh), whose header owns outcome mappings and CI-monitor/daemon exceptions, never by shell liveness, the last status event, or a raw run record.
+Workers parked at approval or fix-review must follow the active gate help.
+A worker hand-editing, committing, aborting, or restarting during an active validation run duplicates pipeline ownership outside the supersession sequence above; steer it back to the gate response flow.
+The worker reports the PR when CI first becomes green rather than waiting for merge monitoring to finish.

 If the session lock cannot be acquired and verified, report its exact diagnostic and remain read-only; another active session is only one possible cause.
 A lock-refused session must not spawn, steer, merge, drain the wake queue, repair supervision, repair a checkout, or perform any other fleet mutation.
 
-The digest itself makes no external-network call and never waits for one.
-Every network check a session start owes - GitHub auth, dead-secondmate relaunch, secondmate convergence, pending handoff delivery, and project clone refresh - runs off the digest's blocking path in a bounded worker owned by `bin/fm-startup-network.sh` and is reported in the digest's own `NETWORK CHECKS` section.
-The locked startup inactive-outcome scan joins that worker so a slow local current-state read cannot block the digest; its findings use the ordinary durable wake queue.
-When that section reports its checks still in progress it names exactly what is unconfirmed; treat none of those as passed until `bin/fm-startup-network.sh report` returns the finished result, while a failed or otherwise actionable result also arrives as a `check: startup-network` wake.
-
-1. **Lock** - acquires the per-home session lock first, before anything mutates shared state, then starts the deferred startup stage above.
-2. **Bootstrap** - detect-only checks (tool/version problems, the worktree-tangle check, harness override, dispatch-profile validation, backlog-backend status) always run, but routine confirmations stay silent by default.
-   When the lock could not be acquired, the worktree-tangle check uses read-only advisory wording without a checkout repair command.
-   Home-local stale Herdr projection cleanup and the six bootstrap MUTATING sweeps - same-home backlog reconciliation, fleet sync, secondmate convergence, secondmate liveness, pending remote handoff retry, and Relay artifact writes - run only when this session actually holds the lock from step 1; the four network ones among them run in the deferred stage rather than in this section.
-   The secondmate liveness sweep deterministically accounts for every registered secondmate: it relaunches only from the recovery-grade `dead` or `missing` states, preserves ambiguous, unreadable, or unreachable remote targets, and reports skipped or failed guarantees as `SECONDMATE_LIVENESS:` lines (`bin/fm-bootstrap.sh`; `bin/fm-backend.sh`'s `fm_backend_agent_state`; `docs/remote-secondmates.md`).
-   Ordinary supervision continues the same guarantee through the watcher's cadence-gated liveness tick over the shared `bin/fm-secondmate-liveness-lib.sh`, so a mate that dies mid-session is relaunched without waiting for the next session start.
-3. **Wake queue** - when locked, drains and presents the durable wake queue without running the inactive-outcome scan inline, and prints the raw records prominently as this turn's first work queue; a clearly labeled status-event annotation may follow a valid `signal` record and includes every status line still unread at the presentation cursor, but never replaces the raw record or current-state reconciliation, and a lapsed watcher chain still surfaces here via the same guard alarm.
-   Presented records remain durable until the handling turn runs the generation-bound acknowledgement printed by the drain.
-   Every locked drain also prints a bounded fleet-wide `OPEN DECISIONS` section when durable decision records remain open, including when the queue itself is empty; reconcile those entries before continuing.
-   A main drain may also print a bounded, one-shot `STATUS OUTCOME BACKSTOP` when a task's newest captain-facing status event has no covering supervision-branch outcome; handle it as a recovered wake even when no queue row remains.
-   The same drain prints every still-unread `note:` line and pending-reply resolution since the last presentation in an unbounded `UNREAD STATUS` section, so an answer buried under a later routine line is not dropped; those lines are not re-printed after that presentation.
-   It also prints a bounded `RECORD DIVERGENCE` section naming every captain call the status log reads as resolved while its backlog task is still held; nothing is closed for you, and `captain-hold-lifecycle` owns the reconciliation.
-   When the lock could not be acquired and verified, the queue is left untouched because no session mutation is authorized, and the guard's tangle/watcher-liveness alarms still print in read-only advisory mode without drain, supervision repair, or checkout repair commands.
-4. **Supervision operating instructions** - after the wake queue and before both digests, the digest emits exactly one operating block for the detected primary harness, followed by the read-once contract that governs them.
-   The script itself never starts supervision; the emitted harness protocol owns the exact wait or wake mechanism.
-5. **Fleet-state digest** - after that read-once contract and ahead of the context digest, the compact backlog listing owned by `bin/fm-session-start.sh`; every `state/<id>.meta`; a bounded tail of each task's `state/<id>.status` (labeled as wake-EVENT history, not current state, with the full log path printed for a deeper read); the away posture (`state/.afk-contract`, plus the `state/.afk` daemon flag where a daemon runs); and one cheap alive/dead read of each task's recorded backend endpoint.
-   That liveness line is a fast presence check only, not a full state read - when you need a crew's actual current state (a run-step, not just "is the pane there"), read it with `bin/fm-crew-state.sh <id>` as before; the digest deliberately skips that deeper, slower read for every task so it stays fast and bounded.
-6. **Network checks** - after the fleet-state digest, the deferred stage's result, or an explicit statement of what it has not confirmed yet.
-   A read-only session runs no network checks at all and says so.
-7. **Context digest and next step** - last of the bulk sections, the full contents of `data/projects.md`, `data/secondmates.md`, `data/captain.md`, `data/captain-shared.md`, and `data/learnings.md`, each clearly delimited, followed by the closing reminder.
-   A file that does not exist prints an explicit `ABSENT` marker, never confused with an empty-but-present file: absence is meaningful (`captain.md` absent means use the firstmate repo's built-in defaults, `projects.md` absent means rebuild it from the clones under `projects/`, etc.).
-   The closing reminder points back to the emitted supervision block and preserves only the lock, afk, Relay, and read-once reminders.

-Bootstrap detects first, asks for consent, and installs only after the captain approves in the current session.

-If static `config/crew-harness` or `config/secondmate-harness` names an unverified adapter, report it and fall back only to a verified adapter rather than launching it.

 ### Validate
 
-For a no-mistakes ship, trigger validation on the same worker after its implementation commit, using the harness invocation owned by `harness-adapters`.
-The task worker that starts a no-mistakes run drives the pipeline and owns every `no-mistakes axi run` and `no-mistakes axi respond` call through the next gate or outcome.
-Firstmate never invokes `no-mistakes axi respond` for a crew-owned run.
-When the captain adds or changes an ask mid-task, append the captain's words without added speaker labels or direct address to that brief's `## Captain's intent` and relay those words to the worker; Firstmate build constraints stay in `## Firstmate spec` or the steer.
-`bin/fm-dod-lib.sh` owns the worker-side `--intent` contract.
-Once validation starts, prefer routing new requirements to follow-up work rather than expanding the current task, unless a new requirement completely invalidates the work being validated; however, the smallest downstream changes needed to keep already accepted product or engineering behavior correct, add behavioral tests where an executable contract exists, or keep documentation accurate remain within the current task even when they touch files not named at intake, and corrections required to satisfy already accepted intent are not new requirements.
-
-Only a current, explicit captain instruction that completely invalidates the work being validated keeps the task with the same worker instead of routing it to follow-up work or handing it to a replacement.
-That worker cancels the active run through no-mistakes axi's supported abort command and confirms through axi status that the run has stopped before changing any code.
-The worker then follows `branch_sync.next_action` from structured axi status: use axi sync's supported guarded recovery only when its code is `recover_custody`, and otherwise proceed only when structured status confirms that branch ownership is already returned and no recovery is required.
-Custody recovery settles branch ownership, not content: the worker must replace the obsolete work from the correct pre-invalidation base rather than building on top of the recovered-but-obsolete head, keeping the obsolete run's own pipeline-fix commits out of what gets validated and shipped.
-Apart from that single supported abort, do not hand-edit, commit, restart, or start a second validation run while the obsolete run still owns the branch.
-Once ownership is settled, validate exactly once against that final head so no obsolete or intermediate head is ever treated as authoritative.
-
-An ask-user finding returns as `needs-decision`; firstmate loads `ask-user-authority` and either decides or escalates per that skill.
-Send the same worker one exact decision naming the decision key, step, action, affected finding IDs, instructions where needed, and exact response command, passing `--resolve-key` so the worker's open decision record closes at answer time.
-Require the matching `resolved` event, forbid `--yes`, and require the worker to process every synchronous return until completion or a genuinely new escalation.
-Resume fleet supervision immediately after the decision lands.
-
-Judge validation by the resolved state line from [`bin/fm-crew-state.sh`](bin/fm-crew-state.sh), whose header owns outcome mappings and CI-monitor/daemon exceptions, never by shell liveness, the last status event, or a raw run record.

+Load `validation-supervision` when a ship starts or already has an active no-mistakes validation run, including a mid-run requirement change or finding.
 
 ### PR ready, landing, and teardown
 
-For PR-based ship tasks, the ready signal depends on mode: `no-mistakes` reports `done [at=<epoch>]: PR <url> checks green` after CI is green, while `direct-PR` reports `done [at=<epoch>]: PR <url>` after opening the PR, each only for a non-draft PR; a lane that deliberately holds a draft declares a wait instead, and `bin/fm-pr-check.sh` refuses to arm merge monitoring on a draft.
-Run `bin/fm-pr-check.sh <id> <PR url>` with the URL copied from that ready signal or the resolved checks-green `fm-crew-state.sh` line - it records `pr=` and the forge's `pr_head=` when available in the task's meta and arms the watcher's merge poll.
-`bin/fm-dod-lib.sh` owns the named-head gate on that ready signal: a ship `done:` whose named head exists only in the worker's disposable copy is not ready (`bin/fm-crew-state.sh` reports blocked, `bin/fm-pr-check.sh` refuses to register, and a secondmate does not publish that done upstream).
-That blocked reading is the gate working, not a stuck worker, so steer the worker on the commit the refusal names rather than waiting.
-A direct-PR worker pushes that commit to its PR branch, and a local-only worker commits it on its ship branch.
-A no-mistakes worker re-validates it with /no-mistakes so the pipeline stays the one publisher; it never pushes from its copy.
-In no-mistakes mode the earlier `done [at=<epoch>]: {summary}` is the pipeline handoff and is not gated.
-Tell the captain the PR's full `https://...` URL copied from the worker's ready line, the resolved checks-green crew-state line, or the task's `pr=` metadata, a concise outcome summary, and the no-mistakes risk level when applicable.
-A captain instruction to merge is explicit authority; `yolo` is the only standing routine merge authority.
-For any custom `state/<id>.check.sh` you write yourself, keep it an ordinary single-link mode-`0700` file, print one line only when firstmate should wake, print nothing otherwise, finish before `FM_CHECK_TIMEOUT`, then bind its current bytes with `bin/fm-check-register.sh <id>` before the watcher may execute it.
-Retire a custom check only through `bin/fm-check-unregister.sh <id>` (or `bin/fm-teardown.sh` for a spawned task); never hand-compose an `rm` with `$STATE`/`$ID`.
-
-Tear down a ship task only after landing is confirmed.
-A teardown refusal for uncommitted or unlanded work is a stop-and-investigate result, never an obstacle to bypass.
-Never force teardown without explicit discard authority.
-After successful teardown, record completion, retain only the configured recent Done history, and re-evaluate queued work whose blockers and time gates have cleared.

-A secondmate is persistent and an empty queue is healthy.

-Before treating the investigation or any visual review as complete, load `captain-hold-lifecycle`; teardown enforces that shared completion gate.
-When a scout's deliverable is a visual artifact the captain will iterate on, keep it alive and follow the crew-hosted Lavish board contract in `docs/configuration.md` rather than arming or polling the board from firstmate.
-When implementation is separately authorized, promote the existing scout through `bin/fm-promote.sh` rather than creating a duplicate task.
-The promoted worker must inventory scratch state, return to a clean default-branch base, carry over only intended fix changes, create the ship branch, and follow the project's selected delivery path while leaving scratch commits and debug edits behind and turning a reproduced bug into the regression test.

 ## 14. Relay
 
-Relay is the public-mention integration older docs and some emitted lines still call "X mode"; its identifiers keep the `FMX_`, `x-`, and `fm-x-` spellings.
-Relay ships inert and causes no behavior change until the home opts in by placing `FMX_PAIRING_TOKEN` in its gitignored `.env`.
-That token is consent for public replies and normal reversible lifecycle actions from eligible mentions, not authority for destructive, irreversible, or security-sensitive action; those still require trusted-channel confirmation.
-`docs/configuration.md` owns activation, generated state, cadence, wire protocol, and opt-out mechanics.
-
-A Relay-only home still requires the live supervision cycle so mentions can wake it without fleet work.
-On an `x-mention <request_id>` or `x-mode-error ...` check wake, load `fmx-respond`, which owns classification, public-safety policy, reply or dismissal, task linking, and follow-ups.
-For every Relay-linked terminal outcome, load that owner and use the promised-final reconciliation when a typed public commitment exists, otherwise post the final completion follow-up before teardown.
-
-A promised final public reply is durable state, never conversation memory.
-Load `fmx-respond` before promising one, on a `public-followup ...` check wake, and whenever the session-start digest lists a public commitment awaiting delivery or an open public loop.
-Only the home holding the relay consent and thread binding ever posts it, so never ask a secondmate or crewmate to find the thread or send the reply, and never recover a terminal result by reading a `done:` sentence.
+When Relay is enabled, load `fmx-respond` for its activation, authority, mention, follow-up, and public-loop contract.

Subject: [PATCH 62/84] fix: route second-mate signal wakes by presented status
 span (#5879)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix: route second-mate signal wakes by their new status span

A second mate's status log is a shared channel carrying many independently
keyed decisions, so judging its signal rows by every decision still open in
the whole log pinned each routine update to main behind any unrelated
parked hold. scopeForUnreadWake (the one owner for Pi and the attended
supervision host) now judges a second-mate signal row by the lines presented
since the last drain, bounded by the existing status-presentation cursor:
a decision, blocked, resolution, or captain-held line, or a line declaring
the key of a still-open decision, keeps the whole row on main, and any
cursor problem falls back to the whole log. Keys are read only at the
status parser's declared positions, with readable time stamps stripped as
bin/fm-classify-lib.sh does. Single-task crewmate and stale routing are
unchanged, and stale and signal rows for one mate keep independent verdicts.

The supervision branch now treats a second mate's done and merged lines as
relayed child outcomes, and fm-teardown refuses the branch actor second-mate
retirement through the existing role-partition helper in both postures.

* no-mistakes(review): Route second-mate resolutions to main only when closing open decision

* no-mistakes(review): Guard bare-verb fold lines and fold resolution spans incrementally

* no-mistakes(document): Clarify second-mate wake routing and retirement documentation

* no-mistakes(ci): The CI failure was a timing-sensitive watcher teardown test, not the PR’s signal-scope code. Extended the bounded wait for both state-directory and home removal. The watcher suite passes locally, and git diff --check is clean

+A second mate's stale wake is a liveness event: report it even when it presents no new status lines.

 # Verdict: routine or captain
 
 Report verdict captain for the finished result of work the captain requested, even when that result is healthy.

+`scopeForUnreadWake` excludes every marked row from what the branch may claim, as well as second-mate signals classified by the span rule below.
+
+A second mate's status log is one shared channel carrying many independently keyed decisions, so its signal row is judged by the lines presented since the last drain rather than by the whole log.
+The row is excluded when one of those lines is a decision, blocked, or captain-held line, resolves a decision open just before it, or declares, in the status parser's key positions, the key of a decision still open in that log.
+A resolution that closes nothing, key-less beside only keyed decisions or keyed for a key never open, stays routine.
+A key-less line otherwise falls back to its verb; an unrelated open decision alone leaves a routine span eligible, while a mixed span goes wholly to main.
+The status-presentation cursor bounds that span, and a missing or unmatched cursor falls back to the whole log.
+Single-task crewmate signals keep their existing Pi payload and attended-host whole-log rules, except that the TypeScript decision fold now ignores bare transition words without a colon or complete key token, matching `bin/fm-classify-lib.sh` on both crewmate and second-mate logs.
 
 For a stale row, `scopeForUnreadWake` folds the mapped task's status log.

Subject: [PATCH 63/84] fix(bin): take the source lock before the lifecycle
 lock in register-extension (#5882)

register-extension took the extension lifecycle lock and then the source
lock, while reconcile republishing an unhandled extension result holds the
source lock and reaches the lifecycle lock through the extension host's
process-event path. Both waits are unbounded and both owners stay alive, so
the two could wait on each other forever and freeze the home's monitoring
cycle.

register-extension now takes the source lock first, matching every other
path that holds both. The lifecycle lock still spans binding resolution
through registration publication, so binding retirement stays serialized.

A new lifecycle-order section in the extension-binding suite, run in the
default aggregate, holds a re-registration inside binding resolution while
reconcile republishes that source's unhandled result and requires both to
finish within a bound.

Fixes #5866

Subject: [PATCH 64/84] fix: chain repository hooks under git -c overrides
 (#5877)

* fix(bin): run the repository's own hooks when git -c carries the per-task hooksPath

The per-task hooks wrappers cleared only the GIT_CONFIG_COUNT override before
looking up the repository's own hooks directory. When core.hooksPath reached git
through git -c (GIT_CONFIG_PARAMETERS), directly or inherited by a child
process, the lookup found the wrapper directory again and exited 0, so the
repository's real hook - such as a pre-push publish guard - never ran and the
push succeeded.

The lookup now ignores GIT_CONFIG_PARAMETERS too, so only the repository's
config files decide its hooks directory, and a failed lookup exits nonzero
instead of skipping the hook. AI-trailer stripping is unchanged.

Fixes #5871

* no-mistakes(document): Document git hook chaining and lookup failure behavior

 Every claude launch's inline `--settings` JSON also carries `"attribution":{"commit":"","pr":"","sessionUrl":false}`, so a spawned worker never writes a Co-Authored-By trailer, Claude-Session link, or generated-with line into a commit or PR body regardless of which settings scopes end up loaded.
 Every fleet launch, Claude included, also receives a pane-scoped `GIT_CONFIG` `core.hooksPath` pointing at `state/<id>.git-hooks`, so git's `commit-msg` hook strips known AI trailers at the commit object even when a runtime injects them after the typed message.

+`bin/fm-git-strip-ai-trailers.sh` owns the identities, the install, and chaining the hooks of whichever repository git is running in, including when `git -c core.hooksPath` supplies the pane's hook override, so a project hook such as husky still runs.
+If the wrapper cannot resolve that repository's hooks directory, the git operation fails rather than silently skipping a project hook such as a pre-push guard.
 That directory is read-only, so a hook manager run inside a fleet pane (lefthook's npm postinstall, `pre-commit install`) fails instead of displacing the strip; install a project's hooks from outside the pane, where the wrappers chain them.
 Per-machine Cursor `cli-config.json` attribution-off is not this contract: it does not travel with Firstmate, defaults back to on when unset, and only feeds the CLI's request to the server, so it suppresses the trailer rather than preventing it.

Subject: [PATCH 65/84] fix(bin): withhold never-send values from dispatch
 resolver requests (#5744)

* feat(bin): add an optional never-send list to typed dispatch resolution

* Added config/dispatch-never-send, an optional local list of literal
  values and re: regular expressions checked against every string of
  the resolver request before it is sent to typesafe.ai
* A match, an unreadable list, or an empty or invalid pattern now stops
  the request and falls back to the off path, so firstmate dispatches
  through its existing intake; the one stderr diagnostic names at most
  the list line number and never the value
* No list, or a list with no match, leaves resolution unchanged

* no-mistakes(review): Match never-send literals across whitespace, drop regex mode

* no-mistakes(review): Inherit the never-send list into secondmate homes

* no-mistakes(ci): ci-2 (Lint 2), caused by this PR and now fixed. The rule that broke: the test script must not share shell variables with a library it sources. The new secondmate-inheritance test in tests/fm-dispatch-resolve.test.sh sourced bin/fm-config-inherit-lib.sh inside a `( ... )` subshell. That lib assigns `out`, so ShellCheck flagged every later `$out` in the test with SC2031. The subshell was the only place this PR sources that lib. The fix runs the propagation in a child shell instead (`bash -c '. "$1" && propagate_inheritable_config "$2" "$3"' _ lib from to`), so the test shell never sources the lib. `bin/fm-lint.sh tests/fm-dispatch-resolve.test.sh` now exits 0, and `bash tests/fm-dispatch-resolve.test.sh` passes. That includes the check that an inherited list is enforced in a secondmate home. ci-1 (Behavior portable serial 8), not caused by this PR, so no code change for it. The only failing test is tests/fm-remote-secondmate-relaunch.test.sh, which fails with "not ok - could not arm the PR poll fixture for the relaunch-ordering test". This PR doesn't touch that test or the code it runs. I reproduced the same failure locally on the base commit ea7c7f7. Main's own CI run on ea7c7f7 (run 36212602588) fails only this job, with the same message. The recent main runs before it also concluded failure

 The scaffold's standard setup, rules, and definition-of-done text is the same in every brief, so leaving it out keeps its safety language from reading as a signal about the task.
 
+**Never-send list (config/dispatch-never-send)**
+
+The optional local, gitignored `config/dispatch-never-send` keeps values you name from ever leaving the machine in a resolver request.
+It has no default entries, and an absent file changes nothing.
+Like `config/crew-dispatch.json`, it is inherited into secondmate homes, so a secondmate's resolver withholds the same values.
+
+Each non-blank line not beginning with `#` is one literal value, matched case-insensitively.
+Every entry is trimmed of surrounding whitespace, and any run of whitespace, in the entry or in the checked text, counts as one space, so a value the brief wraps across lines still matches.
+
+```text
+# Client names
+Example Client Ltd
+```
+
+Before the request is sent, every string in it is checked: the project name, the task text, each rule's `when`, and the fixed question text.
+A match stops the request: the resolver behaves exactly as when it is off, printing one `dispatch-resolve: off (...; nothing sent)` line on stderr and nothing on stdout, making no network or quota call, and exiting 0, so firstmate dispatches through its existing intake.
+A list that is present but not a readable regular file also stops the request the same way rather than sending unchecked text.
+That one diagnostic names the list line number at most and never prints the listed value or the matching text.
+
 **Missing or invalid rules**
 
 An absent rules file, a default-only file, or `rules: []` returns the non-clear reason `no rules to match` without a model or quota request, leaving firstmate's existing routing in control; an existing but unreadable or malformed rules file, including a broken symlink, remains an actionable exit 2 configuration error.

Subject: [PATCH 66/84] feat(jev): add the guard framework contract and the
 memory RSS/swap thrashing guard (#5903)

* feat(jev): add the guard framework and the memory RSS/swap thrashing guard

A Jev guard is a bounded read-only host diagnostic that turns one class of
resource pressure into a machine-readable audit record and a one-line verdict.
This lands the framework contract (docs/jev-guards.md) with one representative
family (Pattern 46, memory RSS and swap thrashing) as the pilot: thin bash
wrapper, stdlib-only python engine, and a behavioral test through the CLI.

* no-mistakes(review): fix jev mem guard fail-open unknown and contract

* no-mistakes(review): fix mem guard rss pairing, memfree, tests, docs

* no-mistakes(review): fix inverted UNKNOWN branch in fail-forcing test

* no-mistakes(review): register docs/jev-guards.md in audience inventory

* no-mistakes(review): simplify wrapper, drop dead top_n, single-source thresholds

* no-mistakes(review): assert exact exit code in fail-forcing test leg

* no-mistakes(review): tolerate any stdout encoding in text output

* no-mistakes(document): Fix guard contract dash style and output wording

+fm-jev-mem-guard.py - Jev Multi-Agent Memory RSS & Swap Thrashing Guard (Pattern 46)
+
+Audits host memory availability (/proc/meminfo) and swap utilization to detect memory
+starvation, swap thrashing, and out-of-control worker RSS expansion across multi-agent seats.
+Prevents catastrophic OOM killer invocations against persistent agent supervisors and tmux sessions.
+
+Thresholds (each named for the CLI flag that carries its operational default; run --help for current values):
+  - --warn-mem-pct: memory utilization warning, percent of MemTotal not available.
+  - --crit-mem-pct: memory utilization critical, percent of MemTotal not available.
+  - --warn-swap-pct: swap utilization warning, percent of SwapTotal in use.
+  - --crit-swap-pct: swap utilization critical, percent of SwapTotal in use.
+
+Invariants:
+  - Read-only diagnostics.
+  - Fail-open: an unreadable or incomplete /proc/meminfo degrades to a graceful status
+    UNKNOWN with a machine-readable reason and a 0 --check exit, never a crash and never
+    a false alarm; an unassessed host reports null measured percentages (JSON null,
+    "unavailable" in human output) instead of fabricated numbers.
+  - Swap with SwapTotal > 0 but no SwapFree line is reported as unknown and never
+    classifies the verdict; a failed top-process listing degrades to an empty list.
+  - Bounded sub-second execution (< 500ms).
+  - Status is OK, WARNING, CRITICAL, or UNKNOWN; recommendation is diagnostic text
+    for the operator, never a command.

+# Jev guard framework
+
+A Jev guard is a bounded, read-only host diagnostic that turns one class of resource or state pressure into a machine-readable audit record and a one-line verdict.
+Guards exist so a supervision loop can distinguish a genuinely wedged worker from a host condition that merely looks like one, without granting any guard the power to change the system it measures.
+This document owns the framework contract every guard family follows; each family's own script header owns its measured signals and thresholds.
+
+## Shape
+
+Each family ships as a pair plus its tests.
+`bin/fm-jev-<name>-guard.sh` is a thin wrapper that resolves its own directory and `exec`s the family engine with `python3`.
+`bin/fm-jev-<name>-guard.py` is the engine: it measures, classifies, and prints.
+`tests/fm-jev-<name>-guard.test.sh` drives the engine through its public CLI and asserts observable output, never engine source text.
+
+## Engine contract
+
+- Read-only diagnostics: a guard never writes to the system it measures and never mutates agent, session, or repository state.
+- Fail-open: permission errors, missing pseudo-files, and virtualized-environment gaps degrade to a graceful `UNKNOWN` verdict with a reason, never a crash and never a false alarm.
+- Bounded: one run finishes in well under a second on a healthy host; a guard that cannot answer in its budget reports `UNKNOWN` rather than blocking its caller.
+- Structured output: `--json` prints one JSON object with `name`, `checked_at`, `status`, `recommendation`, and the family's own measured fields; human output is a short list of the same facts.
+- Deterministic classification: `status` is one of `OK`, `WARNING`, `CRITICAL`, or `UNKNOWN` - the last only when fail-open withholds the verdict; thresholds live in the engine and are named in its header so a reader can audit the verdict.
+
+## Verdict semantics
+
+- `OK` means the measured condition is healthy and the caller should continue unchanged.
+- `WARNING` means the condition is degraded but explained; the caller records it and continues.
+- `CRITICAL` means the condition explains worker silence; the caller should not escalate a wedge while it holds.
+- A guard never recommends a destructive action; `recommendation` is diagnostic text for the operator, not a command.
+
+## Adding a family
+
+Copy the smallest existing pair, keep the wrapper under ten lines, and keep every threshold in the engine with a comment naming the resource it bounds.
+Add the family's behavioral test alongside it and run it through `bin/fm-test-run.sh`.
+A family that needs a host-specific source (a fleet registry, a pool manager, a quota service, or a product's hook store) belongs to the operator's own layer, not this framework.

Subject: [PATCH 67/84] fix: prevent contribution poll starvation on slow
 GitHub reads (#5900)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(bin): stop slow GitHub reads from starving and waking the contributions poll

The poll's fixed budget cut the tail URL's reads short, and any read killed at the bound was recorded as a forge failure, so routine GitHub slowness produced an observation-unavailable wake. A configured FM_CONTRIBUTIONS_BUDGET now rides the generated check shim and is cut down to the watcher's per-check bound with a margin, a read killed at the bound or the deadline is budget refusal that leaves records untouched, and the poll moves to the next URL that still has a full observation reserve instead of ending.

* fix(bin): report the bound when a signal death leaks through fm_run_timed

fm_run_external_timeout trusted the wrapper's recorded status over the runner's own bound verdict, so a read killed by the bound's TERM could surface as 143 and callers such as the contributions poll classified a budget-bound read as a forge failure. When the runner reports the bound, a signal-death status is the bound's own TERM racing the wrapper's bookkeeping and is reported as 124; a natural exit still passes through. The replace-shell probe also moves to the repo's portable BASHPID fallback so the suite runs on the macOS system bash.

* no-mistakes(review): Rotate contribution polling and verify generated budget behavior

* no-mistakes(review): Stabilize contribution rotation across successful observation refreshes

* no-mistakes(review): Exclude settled contributions from live observation rotation

* no-mistakes(document): Document contribution poll rotation and observation reserves

* no-mistakes(ci): Captain, fixed timeout handling with a one-line change preserving natural exit 137. Full session-start and contributions suites, targeted regressions, and lint passed. The timeout suite still fails on the known Bash 3.2 BASHPID issue, left unchanged as instructed. Logs retained in .no-mistakes/ci-evidence/. Remote CI was not rerun

* no-mistakes(ci): Fixed the fixture’s lock-acquisition race with a one-line bounded wait. Forced contention reproduced the CI error before the fix and passed afterward; the ordinary held-lock case, lint, syntax, and diff checks passed. Local Bash 3.2 failures remain: “cleanup lock bound 08 gave up before the marker lock freed” (also reproduced without the fix) and “TERM did not stop a watcher blocked inside a poll”. Remote CI was not rerun

 # poll consumes fm-fleet-snapshot.sh --contribution-input, a local-only read,

Subject: [PATCH 68/84] feat(bin): add config/keep-ai-trailers opt-out to keep
 AI co-author trailers (#5859)

* feat: add keep AI trailers setting

* no-mistakes(document): Drop duplicate keep-ai-trailers line, update Cursor attribution note

* no-mistakes(document): Honor keep-ai-trailers for Devin worker attribution

* no-mistakes(document): Qualify Devin attribution note with keep-ai-trailers flag

* no-mistakes(review): Inherit keep-ai-trailers into secondmate homes

+With the flag absent, every Claude launch's inline `--settings` JSON carries `"attribution":{"commit":"","pr":"","sessionUrl":false}`, every Devin worker config sets `"attribution": false`, and every fleet launch receives a pane-scoped `GIT_CONFIG` `core.hooksPath` pointing at `state/<id>.git-hooks`, where git's `commit-msg` hook strips known AI trailers even when a runtime injects them after the typed message.
+When the flag is present, Claude launches omit those attribution-off settings, Devin worker configs keep the user config's `attribution` setting (Devin's default is on), and fleet launches do not install or select the strip hooks, so Git uses the repository's configured hooks directly.
+`bin/fm-git-strip-ai-trailers.sh` owns the identities, the install, and chaining the hooks of whichever repository git is running in, including when `git -c core.hooksPath` supplies the pane's hook override, so a project hook such as husky still runs when stripping is enabled.
 If the wrapper cannot resolve that repository's hooks directory, the git operation fails rather than silently skipping a project hook such as a pre-push guard.
-That directory is read-only, so a hook manager run inside a fleet pane (lefthook's npm postinstall, `pre-commit install`) fails instead of displacing the strip; install a project's hooks from outside the pane, where the wrappers chain them.
+When stripping is enabled, the hooks directory is read-only, so a hook manager run inside a fleet pane (lefthook's npm postinstall, `pre-commit install`) fails instead of displacing the strip; install a project's hooks from outside the pane, where the wrappers chain them.
+The flag is a home-wide attribution choice, so it is inherited into secondmate homes under the [`secondmate-provisioning`](../.agents/skills/secondmate-provisioning/SKILL.md) inherited-local-material contract and a secondmate's own workers keep AI trailers too.
 Per-machine Cursor `cli-config.json` attribution-off is not this contract: it does not travel with Firstmate, defaults back to on when unset, and only feeds the CLI's request to the server, so it suppresses the trailer rather than preventing it.

Subject: [PATCH 69/84] fix(bin): capture the full viewport for Herdr composer
 reads so a slash-command popup cannot hide the composer (#5876)

* Fix Herdr composer reads blinded by the slash-command popup

Capture the full visible viewport for every Herdr composer state and content read instead of a bounded tail.
Claude Code renders its slash-command popup between the composer and the pane bottom, which pushes the composer outside a tail window.
The pre-Enter payload proof then read an empty composer, judged a typed command unsent, and cleared it without pressing Enter.
The proof-lines value now bounds only the clear cost, not the capture size.
Growing the window adds rows above the composer only, so bottom-most shape selection and prior verdicts are unchanged.
The suffix refusal is kept, and the shared inbox pending-line read stays a bounded tail.
Portable regressions cover the popup-below-composer layout, and the live submit-confirmation guard gains a third exit scenario.
The runtime-backends verification record documents the Herdr 0.9.0 and Claude Code 2.1.283 run.

Closes #5533

* no-mistakes(document): Clarify composer capture bound ownership

* no-mistakes(review): Drop unrequired bracketed-paste Enter fallback from live guard

* no-mistakes(review): Latch trust prompt, check idle composer arm first

+### Claude exit behind the slash-command popup
+
+Measured 2026-09-26 against Herdr 0.9.0 and Claude Code 2.1.283 in an isolated `fm-lab-` session.
+
+Typing `/exit` makes Claude Code render its command popup between the composer and the pane bottom: about 19 menu rows below a solid rule pair, with the footer row last.
+The composer row lands outside a bounded 20-row tail of the pane, so the adapter's bounded composer reads reported the composer as empty while it actually held `/exit`.
+The pre-Enter payload proof then judged the typed command unsent, pressed Ctrl+U, and reported `send-failed` without ever pressing Enter, so `bin/fm-control.sh exit` never exited the worker (and `bin/fm-secondmate-restart.sh` inherited the failure through its exit step).
+
+The fix captures the FULL VISIBLE VIEWPORT for every herdr adapter composer read (`pane read --source visible [--format ansi]`, `fm_backend_herdr_composer_state` and `fm_backend_herdr_composer_content`): the composer is by definition inside the viewport, and the viewport is the one bound that always contains it.
+The shared inbox pending-line confirmation read (`bin/fm-task-inbox-lib.sh`) stays a bounded tail on every backend, herdr included; its payloads are task lines, not slash commands, so the popup shape does not arise there.
+The popup rows sit below the composer's closing rule, which is a structural edge row, so the shared classifier still selects only the composer and the menu rows never read as typed text.
+Verified live in the lab: with the popup up the state read answers `pending` (previously `empty`) and the payload proof returns `/exit` (previously empty), the submit presses Enter, and the Claude process exits, leaving the shell prompt.
+Growing the window only adds rows above the composer, so the bottom-most-shape selection, the footer zone, and every previously passing verdict are unchanged.
+
+Portable regressions (they fail against the bounded-tail reads and pass against the viewport reads):

Subject: [PATCH 70/84] fix(bin): isolate per-task endpoint reads in bounded
 children with a configurable bound (#5917)

Each per-task endpoint read in the session-start fleet digest runs in its own crash-isolated child under the existing timeout helper with a configurable FM_SESSION_START_ENDPOINT_TIMEOUT bound (default 10s).

A hung or killed read becomes that task's endpoint error while the digest continues, and the wrapper banners any abnormal child exit naming its status.

+### Per-task endpoint reads cannot truncate the digest
+
+A per-task backend endpoint liveness read that dies mid-read inside the digest process takes every later stage with it, and a parent wrapper that banners only the runtime-bound exit stays silent about the missing sections.
+The digest now runs each per-task endpoint read in its own bounded child (`FM_SESSION_START_ENDPOINT_TIMEOUT`, default 10s) whose death, hang, or nonzero surprise becomes that task's own `endpoint: error` line, and the parent wrapper banners ANY nonzero child exit, naming the stage and the abnormal exit status.
+Verified on 2026-09-27 with the deterministic process-tree tests that reproduce both failure shapes with real processes and no harness:
+
+```sh
+tests/fm-session-start.test.sh
+# ok - a killed per-task endpoint read becomes that task's error line and the digest completes
+# ok - a hung per-task endpoint read hits its configured bound, reports the task, and leaves nothing stuck
+# ok - a digest child killed mid-stage is bannered by the parent, which still exits 0
+```
+
+The kill test's fake `ps` walks real `/proc` ancestry to TERM the digest bash itself mid-lock-stage, so the parent-wrapper banner path is exercised end to end rather than asserted from output shape alone.
+Both process-tree cases therefore need a readable `/proc` and print a skip line without it, and the companion case that pins a signal death to a nonzero status on the perl timeout mechanism skips when `perl` is absent.
+These guarantees are process semantics, not vendor-emitted signals, so no live-harness guard is owed; the same suite is the refresh command.

 The supervision branch is default-on (docs/pi-supervision-branch.md): whenever this session owns the fleet lock, the watcher extension hands eligible task-local rows from ordinary actionable wakes, plus selected fleet-wide heartbeat reviews, to the in-process supervision branch while main-only rows remain queued for this conversation.
 While the away-posture record `state/.afk-contract` exists the branch takes every row instead, this conversation receives no processing request, and main's standing authority relocates to the branch through the guarded scripts; a wake the branch cannot take and every watcher-failure alarm still reach this conversation, and the first run boundary after the record is archived presents what accumulated (docs/pi-supervision-branch.md "Postures").
 Decision-owned signal and stale routing, including whole-batch precedence and the independent heartbeat exception, is owned by [docs/pi-supervision-branch.md](../pi-supervision-branch.md#components-and-their-owners).

+Both are stored but delivered without a rendered note, while routine outcomes reporting an action, state change, or new result stay rendered with ⛵ then the dim outcome text, and captain outcomes are never silent.
 A captain-facing outcome instead appears as one exact, sequence-keyed visible transcript entry, and while attended then arrives in this conversation as one hidden supervision processing request listing each `[seq N] task: summary` it covers; outcomes recorded while away wait for that request until the record is archived.
 That request is the one turn in which MAIN processes the outcome: give the captain a visible response where one is due, answer or escalate a decision, act on a blocker or failure, or record that no further action is needed, then call the `fm_branch_processed` tool with the highest sequence the request listed, exactly once.
 Only that call closes the outcome; an unrelated, empty, or paraphrased answer leaves it open, and the current unprocessed sequence set is presented again at the next run boundary and at session start until it is acknowledged.

Subject: [PATCH 73/84] feat: make /quiet a statement when attended supervision
 is ready (#5928)

* feat: make /quiet a statement where the attended supervision host runs

On a home that opted into the supervision host, quiet mode is what the
attended host already does, so /quiet now enters nothing there instead of
launching the quiet daemon and writing a record that would park a present
captain's main.

- bin/fm-afk-launch.sh quiet-check says quiet mode needs nothing where the
  attended host runs, or that the session is paused while its
  broken-session latch holds; a quiet enter refuses there before writing
  anything.
- Where the home opted in but the attended host lacks a part (engine,
  tools, verified mirror writer, identifiable main session, valid mirror),
  quiet-check names it and quiet mode falls back to the daemon.
- Under a live away record on that home, quiet-check and a quiet enter
  refuse and name the record, so the return runs first, whatever
  state/.afk says.
- A quiet enter records mode: quiet in the posture record, so start and
  start-native launch the quiet daemon without FM_AFK_MODE, and the away
  refusal wording fires only for away.
- bin/fm-host-mirror.sh check validates the dialog mirror read-only and
  exits 1 on a missing, unreadable, or invalid mirror.
- The quiet and afk skills and the supervision-host docs describe the new
  behavior; homes without the opt-in and Pi homes keep the daemon path.

* no-mistakes(review): Archive the quiet record when a quiet daemon start fails

* no-mistakes(document): Clarify quiet-mode documentation and remove stale duplicates

Subject: [PATCH 74/84] fix: grant Claude workers access to Firstmate task
 channels (#5884)

* fix(bin): grant Claude workers their task-channel dirs via --add-dir

Since Claude Code 2.1.257, a file-tool read (Read/Glob/Grep, and an
Edit's mandatory prior read) of a path outside the working directories
parks --permission-mode auto panes on a one-time interactive question,
and a "Block" answer lands permissions.blockReadsOutsideWorkingDirectories
in user settings, refusing the same reads even under bypass. Firstmate
launches Claude with no --add-dir, so a secondmate's parent-home steering
inbox and a ship or scout worker's launch record, steering inbox, brief
dir, and code-root .agents/skills were all outside: workers wedged on
the question the first time they read a steer.

Every Claude launch, spawn and relaunch, in both permission modes, now
grants exactly the task's channel directories: state/<id>.inbox for a
secondmate (in the parent home), or state/operational-inbox,
state/<id>.inbox, data/<id>, and the code root's .agents/skills for a
ship or scout. Paths resolve to real paths and lazily created channel
dirs are made before launch so the grant never names a not-yet-existing
directory; the whole state/ is deliberately never granted.

The grant keeps the bypass-mode launch argv changed on purpose: it also
protects bypass workers against a machine-recorded Block answer.

* no-mistakes(document): Consolidate Claude launch guidance in configuration reference

* no-mistakes(document): Clarify Claude permission documentation reference

Subject: [PATCH 76/84] fix: reduce remote worker and polling helper process
 churn (#5889)

* fix(bin): stop the remote-job worker busy-polling an idle queue

The serving loop slept 50ms between passes and re-ran state preparation
(chmod on every queue directory), the heartbeat publish, and the stale sweep
on every pass. It now blocks on a worker.wake FIFO that staging,
cancellation, and lane exit nudge, keeps a short fast-poll window after
activity, refreshes the heartbeat at most once a second, and runs the sweep
(which re-applies the queue directories' 0700 modes) at startup and then on
a bounded interval. Lane-owned records are no longer re-read every pass.

Measured with a fork/execve-interposing counter on a --serve worker in a
disposable HOME and queue, bash 3.2, 20-second windows (the counter slows
the old loop to about 5 passes a second, so real-host rates were higher):
  idle worker             146 forks/s, 61 execs/s -> 4.8 forks/s, 3.1 execs/s
  one running long job    232 forks/s, 100 execs/s -> 15 forks/s, 11 execs/s
Stage-to-result latency for a no-op job, idle and back to back, stayed at
about 0.8-1.2s in both versions (dominated by job execution, not pickup).

* perf(bin): drop per-cycle forks from watcher, drain, and lock helpers

The watcher, drain, inactive-reconcile scan, and branch-outcome reads forked
small external commands on every cycle where bash can do the same work.

- fm-wake-lib.sh gains fm_dirname_to, fm_basename_to, and
  fm_epoch_seconds_to, exact stand-ins for $(dirname --), $(basename --),
  and $(date +%s); the clock uses printf %(%s)T on bash 4.2+ and still forks
  date exactly once on stock macOS bash 3.2.
- fm_lock_abs_path, fm_wake_signal_seen_path, fm_path_age, the watcher's
  age_of and wedge timer, and the recovery-marker line count use them or
  plain reads instead of dirname/basename/tr/date/wc.
- window_to_task reads a meta file once instead of two
  grep | tail -1 | cut -d= -f2- pipelines per file per call.
- fm-classify-lib.sh reads uname -s once at source time instead of in every
  status stat helper.
- Libraries sourced every cycle derive their own directory without forking
  dirname, including the backend adapter siblings a subshell re-sources on
  each probe.

tests/fm-fork-free-helpers.test.sh pins each replacement against the command
it replaces on edge-case inputs, under every available bash and both the C
and a UTF-8 locale; CI's stock macOS bash lane runs it under /bin/bash 3.2.

Measured with a fork/execve-interposing counter in a disposable home, one
tmux crew task, FM_POLL=1 (forks and execs per watcher cycle, per run
otherwise):
  watcher cycle      bash 5.3  299/138 -> 199/66   bash 3.2  341/146 -> 224/80
  drain              bash 5.3  492/238 -> 430/200  bash 3.2  567/250 -> 491/212
  inactive scan      bash 5.3   27/14  ->  17/4    bash 3.2   37/14  ->  17/4
  branch-outcome     bash 5.3   40/21  ->  35/16   bash 3.2   48/24  ->  38/19

* test: note the interpreter-expanded version probe for shellcheck

* no-mistakes(review): Fix worker idle bounds and fork-free contributions snapshot

* no-mistakes(review): Coalesce buffered worker wake nudges into one wake

* no-mistakes(review): Coalesce wake nudges via pending marker so publishers never block

* no-mistakes(review): Claim wake nudges atomically via noclobber pending marker

* no-mistakes(review): Release abandoned wake claims only after a 30-second bound

* no-mistakes(review): Drop worker wake FIFO; load path helpers side-effect free

* no-mistakes(document): Document remote worker polling and preemption cadence

* no-mistakes(ci): Fixed both failing CI shards: isolated remote and teardown test fixtures now include fm-path-lib.sh, which fm-wake-lib.sh requires. The three affected tests, fm-lint.sh, and git diff --check pass locally

Subject: [PATCH 77/84] fix: keep remote reply listeners and watcher cycles
 running (#5941)

* fix: keep a successor watcher and remote-reply listeners across the gaps that dropped them

A main-only supervision pass-through exited without leaving a watcher, and each remote-reply poll released its claim until the next cycle, so short-lived listeners stayed down.

* no-mistakes(document): Clarify listener and supervision continuity documentation

* no-mistakes(ci): Fixed the three Greptile findings: failed ingestion leaves one durable capture, failed reads exit instead of relistening, and the disposable-checkout guard rejects state paths outside the marked lab. Added behavioral tests; the remote-reply and watcher-lock suites, shell syntax checks, and git diff checks passed

* no-mistakes(ci): Fixed a race in the wake-queue interruption test: it now waits for the drain to own the lock and enter handling before signaling it. The wake-queue suite, shell syntax check, and diff check pass

Subject: [PATCH 78/84] fix: make attended cutover outcome re-presentation
 check-first (#5925)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix: date replayed branch outcomes and ask main to check current state first

A captain outcome main never acknowledged is presented again, which after a
harness or posture switch, or the first drain after the upgrade whose earlier
presenter never advanced the read cursor, can be days after its situation
settled. The replay read as fresh news, so a PR since merged looked ready.

bin/fm-branch-outcome.sh now adds a "recordedAgo" age (minutes, hours, then
days) to present and unprocessed rows, one owner of that wording for both
presenters. The drain's BRANCH OUTCOMES captain lines and the Pi branch's
processing request name that age and ask main to check the task's current
state first; an outcome already settled needs only the acknowledgement, with
nothing relayed to the captain. Nothing is adopted as processed, so a fresh
home's first outcome is still presented until acknowledged.

* no-mistakes(review): Absent processed marker reads 0; never adopt read cursor

* no-mistakes(review): Require recordedAgo in Pi requests; report undated rows to main

* no-mistakes(review): Keep recordedAgo on captain rows only in present output

* no-mistakes(document): Correct cutover documentation and retire stale migration guidance

* fix: keep settled branch outcomes out of main's reply to the captain

A live Pi primary that took over a host-drain home received the carried-over
outcomes dated and check-first, but its processing reply still told the
captain about an outcome whose decision had since been answered. The request
also claimed every outcome was already shown as an anchor entry in this
transcript, which is false for an outcome carried over from before a restart
or a switch of primary.

The Pi processing request now says each outcome was recorded earlier and may
already have been seen or handled, and that a settled outcome gets no
captain-facing mention at all in the reply or any recap, not even that it is
settled. The drain's BRANCH OUTCOMES header and the supervision docs state the
same rule, and the tests check both delivered texts.

* fix: scope main's outcome reply to what is still open

Telling main what not to say about a settled outcome was not enough: in two
live Pi trials the processing reply still told the captain that an answered
decision was settled. Main now sorts the outcomes by current state first, and
its reply to the captain covers only the still-open ones, written as if the
settled ones had never been listed. With that framing three live Pi trials
kept the settled outcome out of the reply and relayed the open one each time.

The drain's BRANCH OUTCOMES header and the supervision docs use the same
framing, and the tests check both delivered texts.

* no-mistakes(review): Clarify that main acknowledges every presented captain outcome

* no-mistakes(document): Clarify outcome cursor ownership across Pi and host

* no-mistakes(ci): Fixed Pi replay by batching unprocessed captain outcomes oldest-first and acknowledging only through each batch. Verified a marker-less backlog over 1 MiB replays through all batches. A real-drain regression confirms an older keyed decision remains under OPEN DECISIONS after a newer branch row is acknowledged; the check-first instruction now names those decisions. Relevant targeted tests and branch-supervision tests passed; the full host suite timed out

* no-mistakes(ci): Fixed the host drain’s check-first wording in bin/fm-wake-drain.sh; the CI fixture now passes. The full host suite passed the affected fixtures but timed out later. Syntax and diff checks passed

* no-mistakes(ci): Fixed ci-1: abbreviated Pi outcome summaries now stay within 1,024 characters and include a row-specific full-outcome lookup command. The delivered instruction requires reading the full outcome before acting, relaying, or acknowledging it. The new extension-driver regression failed before the fix and passes now; the Pi and supervision-host suites pass

* no-mistakes(ci): Corrected the batching sentence in docs/pi-supervision-branch.md. The cancelled CI check needs no code fix; its clean rerun passed. The Pi branch extension suite and git diff check passed

 A long away window no longer requires a drain per outcome: each task's captain outcomes collapse to one line, subject to the captain byte cap, and visible routine notes past the section's limit collapse into a count; after main acknowledges all captain outcomes no later drain shows anything from the window again.
 A drain that cannot read or project the store (jq missing included), print the section, or advance its read cursor says so and marks nothing it has not shown as read, and it exits nonzero, so the return keeps its catch-up gated until a check drains again and records the presentation, rather than clearing over outcomes a later drain would present again.

 One limit: if the captain goes away and returns while an attended engine turn runs, and the host is terminated before that turn's `branch-outcome` wake is delivered, no immediate wake reaches main.

Subject: [PATCH 79/84] fix: restore primary rewakes after attended main-only
 closes (#5961)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix: wake an idle Claude primary for attended main-only hand-backs

An attended main-only pass-through confirmed a handling handoff for the
successor it leaves running, which flipped the recovery marker to handling.
The Claude Stop hook only rewakes main while that marker reads downtime, so
the close reached no one and an idle primary slept with wakes queued.

The pass-through now leaves the marker at downtime, and a close that turns
main-only at its turn hands the consumed handoff back to downtime before it
reaches main. Regression tests drive the real Stop hook around the real host
on both paths and for the successor's own later close, and a new opt-in live
guard proves it against an idle interactive Claude primary with a pre-fix
negative control.

* no-mistakes(review): Assert live lab Stop-hook registration via parsed settings JSON

* no-mistakes(document): Correct supervision hand-back documentation

* no-mistakes(ci): Fixed the failed downtime-write path so the Stop hook notifies main instead of silently dropping the close. Corrected the live guard’s tracked-hook check and added the requested at-turn main-only scenario. The new regression failed before the fix and passed after it; the host suite, syntax checks, and diff check pass. The credentialed live guard was not run in this CI phase because it writes outside the worktree

* no-mistakes(ci): Fixed the Stop hook’s retry ordering: a crashed host gets its bounded retry before a non-crash hand-back failure is reported. The Stop-hook suite passes, including the crash regression. The host suite passed the failed-marker-write regression but timed out before completing; syntax and diff checks pass

+#   1. the primary is idle with the tracked Stop hook registered and the host

+#   2. a main-only status event passes through the host and leaves a live
+#      successor watcher, and the hook's rewake (ledger outcome=rewake, banner
+#      delivered) starts a primary turn that drains and acknowledges it;
+#   3. that turn's end arms onto the successor, and a second main-only event is

Subject: [PATCH 84/84] no-mistakes(ci): Fixed the Lint 1 failure by deleting 4
 lines from bin/fm-teardown.sh. No lint limits, roots or other files changed.
 Cause: the CI log shows only one failing root, bin/fm-teardown.sh, which
 ended with reason=memory at about 8.39 GiB RSS ("shellcheck: out of memory").
 Every other root ended reason=ok. The merge brought in upstream growth in
 fm-wake-lib.sh, fm-classify-lib.sh and fm-lease-lib.sh, plus fm-path-lib.sh,
 and that pushed teardown's full-analysis ShellCheck past the address-space
 limit. Measured locally, peak RSS was 8.25 GiB at base and 8.55 GiB at HEAD.
 Invariant: fm-teardown.sh should load each of its sourced libraries once,
 from its top-level source block, and should not carry a source path that can
 never run. teardown_herdr_require_prerequisites had a second `.
 "$SCRIPT_DIR/fm-wake-lib.sh"` behind `if ! declare -F fm_lock_try_acquire`.
 That branch could never run. fm_lock_try_acquire is defined only in
 fm-wake-lib.sh, which is sourced unconditionally at the top of the script
 (line 386). All three callers of teardown_herdr_preflight_target (lines 3125,
 3333, 3447) run after that line. ShellCheck still followed this dead source
 and analysed the whole wake-lib closure a second time. I removed the dead
 branch, as the removal-first rule asks. The existing check that refuses
 teardown when the lock functions are missing still stands, so the path still
 fails closed. Source-following itself was not narrowed or redirected, as the
 fm-lint.sh:880 comment forbids. The same wake-lib follows inside
 fm-public-followup-lib.sh and fm-pending-reply-lib.sh were left alone,
 because those libraries are part of other files' lint runs too and the user
 limited this round to teardown. Verification: - I ran the real guard,
 `FM_LINT_REQUIRE_BOUNDS=1 FM_LINT_JOBS=1 bin/fm-lint.sh --telemetry ...
 bin/fm-teardown.sh`, with its default 12 GiB cap. - The original file
 reproduces the CI failure: reason=memory, rc=251, rss 8386716 KiB,
 "shellcheck: out of memory". - The fixed file passes: reason=ok, rc=0, no
 findings, rss 7152892 KiB. That is about 1.2 GiB below the limit where CI
 failed, and lower than base. - These tests all pass with no failures:
 tests/fm-teardown.test.sh, tests/fm-teardown-endpoint-safety.test.sh,
 tests/fm-remote-secondmate-parent-binding.test.sh and
 tests/fm-backend.test.sh. - fm-teardown.test.sh includes the Herdr preflight
 cases (lock contention, preflight refusal, forced secondmate Herdr child
 preflight), so the edited function is exercised. - `bash -n` is clean. - I
 did not add a test, because a lint-memory test would be new machinery and a
 test that reads source text is forbidden. The before/after guard runs above
 are the regression evidence. - I did not run a full local `--partition 1of2`.
 Only teardown failed in the CI log, and that root was checked directly under
 the same guard
