Subject: [PATCH 01/39] fix(spawn): stop passing the removed --tui-mode flag on
 Pi launches (#2)

* docs(stow): generalize read-before-write in the public stow skill (#2091)

The public installer-facing stow skill scoped its classify-then-replace
discipline to TODO/BACKLOG items only, so findings routed to a memory file
had no stated rule against a blind append or a wholesale overwrite.

Step 6 now classifies every finding against the destination's current
contents as new, duplicate, superseding, or obsolete, and states the
considered replacement each classification implies. The outcomes follow the
tiered-memory contract already in the file: an obsolete entry is refreshed,
archived, or replaced in a way that preserves its fact, a duplicate folds
into the entry that already carries it, and a superseded body worth keeping
leaves through step 7's existing exits rather than a second recovery
mechanism.

* fix: resurface durable supervision work after re-arm (#2065)

* fix(watcher): resurface durable work after downtime

* no-mistakes(review): Make watcher rearm recovery durable and cursor-safe

* no-mistakes(review): Persist safe recovery markers across migration lock recovery

* no-mistakes(review): Retain stale lock when recovery marker publication fails

* no-mistakes(review): Preserve delivery-gap recovery and quarantine malformed markers

* no-mistakes(review): Serialize recovery consumption and report acknowledgment failures

* no-mistakes(review): Centralize recovery publication before clearing watcher evidence

* no-mistakes(review): Guarantee recovery evidence across queue and lock handoffs

* no-mistakes(review): Publish recovery evidence before durable wake commits

* no-mistakes(review): Replace recovery marker Perl dependency with Node

* no-mistakes(review): Keep interrupted wakes durable until handling acknowledgment

* no-mistakes(review): Add post-handling durable wake acknowledgements

* no-mistakes(review): Enforce post-handling acknowledgement across recovery and AFK return

* no-mistakes(review): Bind wake acknowledgements to recovery generations

* no-mistakes(review): Align wake regressions with generation-bound acknowledgements

* no-mistakes(document): Document durable re-arm recovery semantics

* no-mistakes(lint): Resolve ShellCheck warnings in recovery and watcher tests

* no-mistakes: apply CI fixes

* test(watcher): assert post-handling wake replay

* no-mistakes(review): Delay handling transition until successor launch is established

* no-mistakes(review): Confirm wake handling only after successful prompt delivery

* no-mistakes(lint): Suppress false positive for recovery action output

* no-mistakes: apply CI fixes

* no-mistakes: apply CI fixes

 The classification predicates (the captain-relevant verb set, declared-pause vocabulary, signal/stale tests, and fleet-scan) live in the shared `bin/fm-classify-lib.sh`, the same library the always-on watcher uses for its own triage when afk is off, so the two modes apply one identical policy.

 Pi has no permission system, so crewmates are always autonomous.
-Pi's `packages/coding-agent/docs/settings.md` UI and display section documents `regular` as the `tuiMode` default, `fullscreen` as experimental, and `--tui-mode` as its startup override; fullscreen can bury steers by rewriting scrollback, so `fm-spawn` always passes `--tui-mode regular` for Pi-family crews.
+Pi 0.83 removed the former `--tui-mode` startup option and its `tuiMode` setting, while remaining an interactive terminal application by default; `fm-spawn` therefore omits the obsolete option so Pi-family crews can start on current installations.
 `pi-signed` is the signed wrapper identity verified on version 0.82.0 and exposes the same CLI and TUI behavior as Pi.
 Firstmate launches the selected executable name from `PATH`, records `pi-signed` without normalization, and refuses rather than falling back to `pi` when that wrapper is unavailable.
 The observed signed process tree is an exact `pi-signed` wrapper parent with the Pi application as its child, while tmux reports the foreground command as the exact `pi-launcher` name for both selected executables.

 Actionable wakes include captain-relevant status signals, no-verb signals whose crew is not provably working, authenticated check output such as PR merge polling or a Relay mention, stale panes whose crew is not provably working whether their status log looks terminal or non-terminal, provably-working stale panes that persist past `FM_STALE_ESCALATE_SECS`, declared external waits that remain paused past `FM_PAUSE_RESURFACE_SECS`, and heartbeat backstop hits.
 Repeated provably-working stale escalations on the same unchanged pane add an escalation count to the wake reason and, at `FM_WEDGE_DEMAND_INSPECT_COUNT`, a `demand-deep-inspection` marker.
 A busy pane is otherwise exempt from staleness, but only until its latest `state/<id>.turn-ended` marker reaches `FM_BUSY_TURN_MAX_SECS`, or its `state/<id>.meta` spawn record reaches that age before any turn completes; past that bound it is routed through the same wedge escalation, with the identical reason, escalation count, and `demand-deep-inspection` marker, for inspection only - never an automatic interrupt, signal, or restart.
-Those actionable wakes are written to a durable local queue (`state/.wake-queue`) before detector state advances, so a missed process exit can be recovered by draining the queue.
+Those actionable wakes are written to a durable local queue (`state/.wake-queue`) only after generation-bound recovery evidence is published, so an interrupted watcher or handling turn can be recovered without losing the queue record.
 When a canonical validated PR poll returns exactly `merged`, the watcher appends that durable notification before publishing a private receipt bound to the poll's registration, bytes, file identities, metadata, provider, URL, and task ID.
 The receipt makes retirement 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=`.
 A concurrent replacement remains armed, every non-merged or invalid observation remains unchanged, and retirement never performs task or persistent-secondmate cleanup.

 Fresh stale panes use the same current-state read before trusting the status log, so an active run or a proven busy worker outranks an old captain-relevant status-log line left behind before validation.

+Each `fm-wake-drain.sh` presentation runs the same liveness guard as the supervision scripts, so a lapsed watcher chain surfaces even on a turn that only handles queued wakes.
 Routine watcher polling, supervision no-ops, elapsed waiting time, and absorbed benign wakes stay silent.
 A declared external wait trades that silence for one bounded recheck per pause window, so a forgotten pause cannot remain invisible indefinitely.
 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 drain (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 it is explicitly resolved while each drain reads only new status-log appends.

 The explicit resolution is written by the actor that answers, not the busy worker: `fm-send`'s `--resolve-key` appends the closing `resolved` line to this home's own copy of the ledger at answer time, which covers crewmates, local secondmates, and remote secondmates identically because a remote mate's escalations reach that local copy through the parent-replies ingest and only the answer message itself crosses the transport.
 `bin/fm-crew-state.sh <id>` is the cheap current-state read for an actionable heartbeat review: it attributes a no-mistakes run, active or terminal, only when it matches the crew's branch and current code identity, then keeps that run-step authoritative even if the pane has closed.

Subject: [PATCH 02/39] feat(fork): sync upstream into live fork main (#3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add permanent fork main integration workflow

* no-mistakes(review): gate startup upstream probe on validated fork topology

* no-mistakes(test): retire upstream-accepted divergences on re-provable Git evidence

* no-mistakes(document): add fork manifest to shared tracked material list

* fix(fork): make integration workflow actor-safe

* no-mistakes(review): guard empty resolved revert and tighten fork path handling

* no-mistakes(document): correct fork-upstream network-check and fork script doc facts

* no-mistakes(document): name fork-upstream probe in label; deduplicate fork skill

* docs(stow): generalize read-before-write in the public stow skill (#2091)

The public installer-facing stow skill scoped its classify-then-replace
discipline to TODO/BACKLOG items only, so findings routed to a memory file
had no stated rule against a blind append or a wholesale overwrite.

Step 6 now classifies every finding against the destination's current
contents as new, duplicate, superseding, or obsolete, and states the
considered replacement each classification implies. The outcomes follow the
tiered-memory contract already in the file: an obsolete entry is refreshed,
archived, or replaced in a way that preserves its fact, a duplicate folds
into the entry that already carries it, and a superseded body worth keeping
leaves through step 7's existing exits rather than a second recovery
mechanism.

* fix: resurface durable supervision work after re-arm (#2065)

* fix(watcher): resurface durable work after downtime

* no-mistakes(review): Make watcher rearm recovery durable and cursor-safe

* no-mistakes(review): Persist safe recovery markers across migration lock recovery

* no-mistakes(review): Retain stale lock when recovery marker publication fails

* no-mistakes(review): Preserve delivery-gap recovery and quarantine malformed markers

* no-mistakes(review): Serialize recovery consumption and report acknowledgment failures

* no-mistakes(review): Centralize recovery publication before clearing watcher evidence

* no-mistakes(review): Guarantee recovery evidence across queue and lock handoffs

* no-mistakes(review): Publish recovery evidence before durable wake commits

* no-mistakes(review): Replace recovery marker Perl dependency with Node

* no-mistakes(review): Keep interrupted wakes durable until handling acknowledgment

* no-mistakes(review): Add post-handling durable wake acknowledgements

* no-mistakes(review): Enforce post-handling acknowledgement across recovery and AFK return

* no-mistakes(review): Bind wake acknowledgements to recovery generations

* no-mistakes(review): Align wake regressions with generation-bound acknowledgements

* no-mistakes(document): Document durable re-arm recovery semantics

* no-mistakes(lint): Resolve ShellCheck warnings in recovery and watcher tests

* no-mistakes: apply CI fixes

* test(watcher): assert post-handling wake replay

* no-mistakes(review): Prevent successor loops and adopt legacy wake generations

* no-mistakes(review): Rearm durable wakes without recursive successor recovery

* no-mistakes(review): Align recovery tests with handling marker state

* no-mistakes(review): Delay handling transition until successor launch is established

* no-mistakes(review): Confirm wake handling only after successful prompt delivery

* no-mistakes(review): Acknowledge AFK wakes only after evidence publication

* no-mistakes(review): Prevent AFK wake loss before post-handling acknowledgement

* no-mistakes(document): Document durable wake acknowledgement semantics

* no-mistakes(lint): Suppress false positive for recovery action output

* no-mistakes: apply CI fixes

* no-mistakes: apply CI fixes

* ci: measure Herdr automation on Windows runners (#2100)

* ci: add Windows Herdr automation spike

* ci: run Windows spike on its pull request

* fix: wait for Windows Herdr command output

* fix: run ANSI probe in pane shell

* ci: keep Windows Herdr spike manually triggered

* docs: clarify Windows Herdr spike verdict

* feat(ahoy): guide captains through open decisions (#2099)

* Add guided ahoy decision flow

* no-mistakes(document): Document guided Ahoy decision flow

* fix(stow): enforce startup-memory budget decisions (#2110)

* Harden stow memory budget policy

* Refine internal stow offload policy

* no-mistakes(review): Enforce shared-budget decisions and autonomous offload

* fix(spawn): refresh pooled worktrees from origin before launch (#2116)

* fix(spawn): refresh pooled worktree base

* no-mistakes(document): Document spawn base-freshness invariant

* no-mistakes: apply CI fixes

* fix(composer): unify safe classification across backends (#2102)

* refactor(composer): one shape owner behind thin capture adapters, whole matrix fixed

Consolidate every composer shape - bordered boxes (all families, geometry,
titled bottom borders), bare agent-glyph rows and their wrap regions,
opencode's left bar, and pi's identity-gated separator pair - into
fm_composer_classify_screen in bin/fm-composer-lib.sh. Adapters now
contribute only a capture and a declarative capability descriptor
(styled/cursor/identity/rows); capability differences change how confidently
a shape is judged, never what the shapes are, so a new harness shape is
teachable in exactly one place.

Correctness fixes landed as part of the consolidation (audit
data/fm-composer-consolidation-audit-s1):
- locale-safe Unicode-space normalization in the shared owner (closes the
  fleet-wide half of #1988; cmux's local byte-exact NBSP case deleted;
  naming converges with PR #1995's normalization primitive)
- muse's bare glyph joins the shared set, unbreaking muse on herdr/cmux/orca
- orca learns the borderless bare shape, drops its backward-paged composer
  window, and can no longer classify a stale startup banner as the composer
- tmux tolerates a titled bottom border, unbreaking grok steering
- the left-bar shape makes opencode readable on every backend
- zellij gets a real classifier through dump-screen --ansi, replacing the
  content-diff submit heuristic that could confirm an undelivered message
  and close a --resolve-key decision (the fleet's only false positive)
- fm-spawn's kimi launch-readiness regex (the fourth shape copy) now routes
  through the shared classifier

The strict blank-row posture applies fleet-wide (captain decision
blank-row-injection-posture): no positive container proof = unknown = defer,
replacing tmux's permissive blank-cursor-row rule. Away-mode injection was
re-validated end to end on real tmux (defer on partial input and unproven
rows, clean delivery with swallowed-Enter retry into proven-empty
composers). The tmux submit core gains a baseline-idle turn-started
conversion so pi steering stays confirmed while its working screen hides
the composer; busy conversion without that baseline remains forbidden.

Plain-capture backends now degrade a glyph row carrying trailing text to
unknown instead of a false pending, per the approved capability rule.

Portable regressions pin the full byte-capture matrix from the audit under
a UTF-8 locale and LC_ALL=C, the strict-vs-permissive divergence, and
deliberate signal separation; the opt-in live guard
(tests/fm-composer-matrix-live-e2e.test.sh) verified every installed
harness against the real classifier, recorded in
docs/verification/runtime-backends.md.

captured outcome - instead of burning an agent turn per re-check.

The pair is stored privately under state/when/ and hash-bound by a trust record
the same way fm-check-register.sh binds a custom check, so a mutated spec is
refused without executing anything. A durable exclusive fired marker claimed
before the action makes restarts and re-polls unable to double-fire; every
failure path (mutated spec, condition error past budget, expired deadline,
failed action, uncaptured earlier fire) ends in a terminal captured outcome
that wakes firstmate rather than a silent retry. Eligibility stays a firstmate
judgment: only exact, safe, reversible actions may be bound, and judgment-
needing or destructive actions keep the wake-and-decide flow.

The open-decisions fold only recognized a [key=<slug>] token between the

shape with the colon first (needs-decision: [key=x] note) silently
folded its stated key into the shared "default" bucket, so two open
decisions could collapse into one record and fm-send --resolve-key <x>
refused to close the decision it plainly named.

A complete token at the head of the note is now an equivalent stated-key
position for every keyed verb, shared by the whole-file and incremental
folds through the one _fm_decision_key owner. The documented
before-colon position wins when both are present, a token deeper in the
note stays prose, a bare keyless line still folds to "default", and a
stated-but-malformed slug is rejected rather than rewritten to
"default". A consumed note-head token is stripped from the note so both
positions yield identical records, and the incremental fold version is
bumped so persisted cursors folded under the old interpretation are
rebuilt from the authoritative log.

Fixes #2109

* fix(bin): prevent watcher recovery acknowledgement livelock (#2212)

* fix(bin): keep a recovery acknowledgement valid across republication

A watcher cycle that opened and closed while the model handled its drained
wakes minted a fresh recovery generation, which invalidated the exact
acknowledgement the drain had just printed. That acknowledgement then consumed
nothing, so the marker stayed pending and every later arm spent its whole cycle
re-announcing the same recovery instead of supervising - a livelock the home
could not leave on its own.

A downtime publication now reuses the generation of an outstanding handling
episode, so a close during the handling window cannot orphan the printed
acknowledgement. The acknowledgement itself separates its two facts: queue-row
consumption is bound to the monotonic --ack-through sequence and always
happens, while only retiring the episode is bound to --recovery-generation. A
generation that moved on is a non-fatal result that names its own remedy
instead of a refusal that consumes nothing.

The relay's poll payload can carry in_reply_to_chain, an oldest-first

procedure only ever read the immediate in_reply_to parent, so referents
like "this" in a standalone mention stayed unresolvable even when
context was delivered.

backward-compatible: often absent today, kind label not required),
resolve referents against the whole transcript, and extend the

kind=history entries. Document the field's wire shape in

* fix(bin): strip every bracket tag, not just [key=...], from a status verb

status_line_verb only stripped a leading "[key=...]" token before the
colon, so a remote secondmate reply's leading "[corr=...]" correlation
tag stayed glued onto the returned verb word ("needs-decision
[corr=...]" instead of "needs-decision"). The open-decisions fold's
verb match then silently failed to recognize the line at all, so
fm-send --resolve-key refused to close a decision that was plainly
open on the status line.

Generalize the parser to strip every "[name=value]" tag before the
colon, in any order and count, so local and remote replies fold
identically.

* fix(bin): collapse duplicate supervision wakes (#2287)

* fix: collapse duplicate supervision wakes without losing legitimate updates

One remote-secondmate note produced two handling turns (a procevent check
wake published before autohandle, then a signal wake for the same mirrored
bytes), already-ingested replays such as a cursor-loss whole-log recapture
still woke with nothing to do, this home's own bookkeeping closes (fm-send
--resolve-key, the pending-reply escalation close, the captain-held
transfer) re-woke the session that wrote them, and turn-ended-only wakes
were annotated with already-announced status lines that looked like fresh
progress.

Dedup rules, each at its layer's one owner:
- fm-procevent.sh: an adapter may declare 'self-announcing'; the runner
  then applies first and publishes a check wake only for what remains
  unhandled. fm-procevent-remote-reply.sh declares it: the mirrored status
  append is the single announcement, so a fully applied capture publishes
  nothing and a byte-identical replay stays completely quiet. All other
  adapters keep strict publish-before-apply.
- fm-wake-lib.sh: fm_wake_signal_sig/seen_path/seen_current now own the
  watcher's signal signature and .seen-* marker format, plus
  fm_wake_status_append_self_announced, the guarded bookkeeping append
  that advances the marker only over exactly its own bytes and fails
  toward waking on any pending or interleaved foreign write.
- fm-send.sh, fm-pending-reply-lib.sh, fm-decision-hold.sh: bookkeeping
  closes go through that guarded append; escalation opens stay plain
  appends because a new blocker must wake.
- fm-wake-lib.sh annotations: a historical (turn-ended-only) row skips its
  status annotation only when the file's signature provably matches the
  seen marker; anything unannounced keeps annotating.
- fm-classify-lib.sh: a kind=secondmate task's status signal is never
  absorbed as provably-working, because that stream is the routed-reply
  channel the parent must read.

Also fixes a pre-existing exit-path deadlock the regression run reproduced:
a TERM inside a recovery-marker critical section left fm_lock_try_acquire
spinning against this same process's abandoned hold; a self-held lock is
now reclaimed (a subshell still waits on its parent's live hold).

Regression tests drive the real wake functions and executables in both
directions: each duplicate case collapses, while a new remote reply, new
decision, new blocker, merge result, failure, first status change, and a
later different note on the same task all still wake.

# Conflicts:

* fix(composer): read cursor-agent's reverse-video placeholder as idle

cursor-agent renders its idle composer placeholder dim (SGR 2) but paints the
cell under the terminal cursor in reverse video (SGR 0;7). Reverse video is
neither dim nor a dark truecolor foreground, so the shared ghost stripper keeps
that one character and an idle composer reduces to a lone `P`. Judged on its
own, that remnant reads `pending` on a genuinely idle pane, which defers
away-mode escalation indefinitely on the styled cursorless backends.

Teach the ONE fleet-wide classifier the shape instead of adding an adapter-local
copy: register `→` as an agent prompt glyph so the composer row is structurally
findable at all (without it the bottom-most shape is a stale shell prompt echo
in the scrollback), add both verified placeholders to the idle set, and consult
the styling-independent plain row when the styled row is only a remnant.

The plain-row branch demands the remnant be a proper, strictly shorter substring
of a plain row matching a fully anchored placeholder. Real typed text is
uniformly bright, so stripping leaves it equal to the plain row and it stays
`pending` - verified live against a pane where the typed text was exactly the
placeholder string.

Verified live on cursor-agent 2026.08.11-e8db854; the regression pins the real
captured bytes and asserts the remnant survives stripping, so the case cannot go
vacuous if the stripper later learns SGR 7.

* feat(cursor): narrow cursor identity and order its marker before CLAUDECODE

Cursor ships two executable names - `cursor-agent` and the legacy alias `agent`
- and runs as a bundled node script, so tmux reports the pane command as a bare
`node`. Neither `agent` nor `node` can be trusted by name, so identity gets one
owner in bin/fm-cursor-lib.sh that demands cursor's own name or install tree in
the path or argv[0], from the structural signal only. Probing an arbitrary pid's
executable during a liveness poll would execute a stranger's binary, which is
the hazard that rule exists to close.

Two consequences wired up:

Detection. cursor-agent does NOT clear an inherited CLAUDECODE, so a cursor
worker launched under a claude primary carries both markers and whichever is
tested first wins. The cursor markers are ordered ahead of the CLAUDECODE check;
fm-spawn additionally clears foreign markers at the launch boundary. Both are
kept deliberately - launch sanitization only covers sessions fm-spawn started,
while the ordering also covers a cursor session started by hand. Verified live
that CURSOR_INVOKED_AS is set on the agent process and CURSOR_AGENT=1 on the
child/tool processes fm-harness.sh actually runs as.

Pane liveness. A cursor pane now classifies `agent`. An unrelated node or agent
stays `other`, which the liveness callers already fold into `ambiguous` rather
than `dead`, so a stranger's node pane is never reported agent-free.

Resolution prints the STABLE launcher rather than the canonical target: identity
is proven through canonicalization, but cursor's canonical path carries a
version its own auto-update replaces, and pinning that would strand a task on a
version that can vanish.

The regression drives the two identity signals apart - a cursor-named executable
outside any cursor tree, and a non-cursor-named alias inside one - and asserts
each carries a verdict alone, so no single vendor string is load-bearing. Its
negative controls are real spawned processes, not fixtures.

Verified live on cursor-agent 2026.08.11-e8db854.

* feat(cursor): classify cursor busy state from its own turn transcript

Cursor shipped as "unknown cursor-unverified" on the premise that it exposes no
semantic turn lifecycle, only a rendered "Working" footer. That premise is
wrong: cursor-agent persists an append-only JSONL transcript per conversation
and brackets every submitted turn with a role:user open and a typed turn_ended
close. Verified live on 2026.08.11-e8db854, including the interrupt path, where
Escape closes the turn with status "aborted" - so this source covers manual
interruption, which Claude's Stop hook does not.

That makes it a genuine pull source in the muse mould rather than the rendered
text the redesign forbids: no writer, no arm, no gen, nothing seeded that could
never be cleared. Cursor's `ctrl+c to stop` footer stays out of the verdict, and
herdr's narrower native streaming state cannot stand in for it either.

Binding deliberately does not reconstruct cursor's workspace-slug directory
name. That slug collapses path separators, so rebuilding it would be a guess
that could bind the wrong pane; cursor records the exact absolute workspace path
in each project's .workspace-trusted, and the binding matches on that. A
conversation recorded as prior at spawn is excluded, so a relaunch in a reused
worktree folds its own turn rather than its predecessor's. Requiring a unique
remaining conversation keeps zero and several both unknown, because neither
proves anything about the current turn.

The regression pins the fold with real transcript files and asserts the
dangerous direction stays closed: an unresolvable binding, a record-free file,
an unclaimed workspace, and a workspace-path PREFIX all read unknown, never
idle. The prefix case uses an opaque fixture slug so a slug-rebuilding
implementation cannot pass it.

* feat(cursor): make the cursor launch runnable and give it lifecycle control

Five gaps that together kept a cursor crewmate from being drivable end to end.

Launch. The template invoked `cursor agent`, but `cursor` is not the CLI - the
installed names are `cursor-agent` and the legacy alias `agent` - so the command
could not run at all on a machine with a normal cursor install. It now resolves
through the verified owner, which also refuses a spawn loudly instead of leaving
a pane that dies with command-not-found and reads as a wedged worker.

Session binding. fm-spawn writes state/<id>.cursor-session so the busy fold can
find this pane's transcript, and teardown removes it.

Lifecycle control. No cursor PR touched fm-control-lib.sh, so
`fm-control <id> interrupt|exit|relaunch` could not drive a cursor worker at
all. Verified live: interrupt is a single Escape, exit is /exit, and cursor does
NOT repollute its composer with the cancelled prompt, so unlike muse it needs no
clear key. Secondmate is refused, matching the spawn refusal.

Submit acknowledgement. cursor parks its terminal cursor outside its composer,
so the composer verdict on tmux is always `unknown` and a submit could never be
acknowledged from the composer alone. The submit core's existing idle-to-busy
transition covers that case, but only if the pane's busy footer is recognised,
so cursor's `ctrl+c to stop` joins the harness-less default union the submit
cores read. The TOKEN is matched rather than the spinner verb: the same version
rendered both `Working` and `Running` in consecutive turns.

Bootstrap. A configured cursor crew harness with no cursor executable is now a
loud MISSING diagnostic rather than a first-spawn failure, and it accepts either
installed name.

Interrupt cancellation is deliberately left unconfirmed. The transcript does
type an aborted close, but its post-interrupt write latency measured as
variable - sometimes seconds, sometimes not within twenty - so a claim built on
it would be unreliable. Normal turn completion is prompt, which is what the busy
fold actually depends on.

Two inherited tests are corrected rather than deleted: the busy test asserted
cursor could have no semantic source, and the launch test pinned the literal
`cursor agent` string. Both now pin the verified behaviour, including that the
launch never allocates a second worktree.

* docs(cursor): record the verified crewmate facts and extend the drift guard

The inherited cursor entry was written against 2026.08.04-aaa8809 and several of
its claims no longer hold: it named `cursor agent` as the binary (not the CLI
name), listed six Grok model ids of which the live catalog now returns two, and
recorded busy state, exit, interrupt, and skill invocation as unverified.

Replaced with what was measured against 2026.08.11-e8db854, including the two
facts most likely to be rediscovered painfully: cursor runs as a bundled node
script so its pane title is a bare `node`, and it parks its terminal cursor
outside its composer, which makes the tmux composer verdict permanently
`unknown` by design rather than a defect to chase.

Model ids now route to `--list-models` for the account instead of a fixed list,
since that list is exactly what drifted.

The live drift guard covers cursor, resolving it through the same verified owner
fm-spawn uses and passing --trust so the probe cannot hang on the workspace
prompt. Run against every installed harness: 8 checked, all alive, with cursor
reporting title='node' foreground=[.../cursor-agent] - the drift shape this
guard exists to catch.

* refactor(composer): move the delivery busy footers to the shared owner

The per-harness rendered busy footers lived in bin/fm-tmux-lib.sh under
FM_TMUX_* names, so cursor's `ctrl+c to stop` signature - and every other
harness's - was reachable only from tmux. That placement was wrong on its own
terms: herdr, zellij, cmux, and orca run the same harnesses and face the same
question these footers answer, which is whether a submitted Enter actually
landed. Nothing about the signature is tmux-specific.

Moved verbatim into bin/fm-composer-lib.sh, the shared composer/delivery owner
every backend already sources, and renamed to FM_DELIVERY_* so the names stop
claiming a scope they never had. All five adapters now reach cursor's signature;
verified per adapter rather than assumed.

The boundary the move must not blur is stated where it now lives: this is a
DELIVERY guard, never a worker-state source. Confirming a keystroke landed is a
different question from asking what a worker is doing, and bin/fm-busy-lib.sh
remains the semantic owner that forbids classifying a harness from rendered
text. Cursor still classifies only from its transcript fold, which is already
backend-agnostic because it folds a file rather than reading a pane - the same
verdict on all six backends.

The old FM_TMUX_* aliases are dropped rather than kept as dead shims: nothing
outside the moved block referenced them except fm-busy-lib.sh's grok fallback,
which now reads the new name. The documented operator override, FM_BUSY_REGEX,
is untouched.

Also removes a dead duplicate CURSOR_INVOKED_AS check in bin/fm-harness.sh,
unreachable behind the marker check above it.

* fix(composer): bound a bare composer's wrap region at a half-block rule

A live cursor crewmate on herdr classified its IDLE composer as `pending`, and
fm-send consequently exited 1 with "delivery unconfirmed" on a message that had
actually landed. The cause is not cursor-specific.

Herdr draws a composer's top and bottom rules with the half-block glyphs U+2584
and U+2580 rather than the box-drawing family. fm_composer_row_has_edge knew
only the box-drawing set, so no box was detected; the composer was found as a
BARE row, and its wrap region - which extends while rows are non-blank and carry
no structural edge - walked straight through the composer's own closing rule and
swallowed the model and path footer below it. That footer is real text, so the
region classified pending on a genuinely idle pane.

Teaching the shared edge detector the half-block glyphs bounds the region at the
closing rule. Measured on the captured bytes of a real herdr cursor pane: the
same capture that read `pending` now reads `empty`.

This is a shared shape-path change, so it is deliberately narrow - it adds
glyphs to the edge vocabulary and changes no verdict logic - and the whole
composer and backend suite is green, including the other harnesses' herdr
fixtures.

The regression pins the real captured shape and asserts the footer content is
genuinely present, so the case cannot pass vacuously if the region were ever
bounded for some unrelated reason.

* fix(herdr): confirm a cursor submit from the rendered-footer transition

Herdr's composer-shape fix made an idle cursor pane classify `empty`, but
`fm-send` still exited 1 with "delivery unconfirmed" on messages that had
actually landed. Live measurement found the second, independent cause.

Herdr reports a cursor pane `agent_status=blocked` in EVERY state - idle,
mid-turn, and after - so the submit path's idle-baseline native confirmation is
structurally unreachable for cursor and every send falls into the composer
branch. That branch reads cursor's mid-turn composer row, which renders its own
`Add a follow-up` placeholder beside a right-aligned `ctrl+c to stop`. That
token is composer content, so the verdict is `pending` on a composer holding no
user text at all, and the Enter-retry budget then reports pending.

The escape is the same semantic signal the native path uses, read from the
pane's verified busy footer instead of native agent-state, and it is the
rendered-footer twin of the tmux submit core's turn-started confirmation: an
idle-to-busy transition ACROSS our Enter proves the harness accepted the
submission. The baseline is taken before the first Enter and only when the
native baseline was not legibly idle, so the idle-baseline path still never
reads pane content and a pane already mid-turn before we typed keeps reporting
`pending` rather than borrowing another turn as proof of this delivery.

The composer verdict is deliberately NOT relaxed. A right-aligned status token
on the composer row stays content for every other caller, including the
away-mode pre-injection guard, and the shared cursorless submit core is left
untouched so zellij, cmux, and Orca keep the behavior their own follow-up owns.

Verified live on herdr 0.8.0 and cursor-agent 2026.08.11-e8db854 in an isolated
lab session: `fm-send` now exits 0 and the steer executes, interrupt cancels a
running turn, `/exit` stops the agent, and teardown clears the record. All seven
panes of the running default session classify identically before and after the
shape fix, so no other harness regressed.

* fix(bin): require quota-axi 0.1.25 (#2300)

* fix: raise quota-axi floor to 0.1.25 for Cursor CLI quota awareness

Homes on latest main need quota-axi #87 so Desktop-absent CLI machines report a fresh Cursor quota instead of a false sign-in-required.

* no-mistakes(document): Update quota floor documentation pointer

* fix(bin): prevent false Pi watcher alarms during hand-offs (#2304)

* fix(guard): stop the false send-time watcher-down alarm on Pi primaries

On a Pi primary the watcher process is not the liveness signal. The Pi
extension tears the watcher down on every actionable wake and spawns the
replacement itself, so the singleton lock is legitimately unheld between
cycles: every one of the 799 cycles in a live primary's ledger ends with
lock_after=pid:none, and a live capture caught the guard verdict flipping to
no-watcher during one hand-off with the beacon 63s old.

bin/fm-guard.sh classified Pi as a persistent-watcher harness, which demands a
live identity-matched lock holder at all times, so any guarded command landing
in a hand-off painted the full WATCHER DOWN - SUPERVISION IS OFF banner and
told firstmate to repair a cycle the extension already owns and is restoring.

Add an extension supervision model for pi and pi-signed. A live
identity-matched watcher stays the ordinary healthy state; an unheld lock is
healthy only while the beacon is fresh within grace AND a live Pi session
provably owns continuity - both primary extensions recorded in their state
markers at their current on-disk builds by the process named in state/.lock,
with that process still alive. Without that proof the banner fires exactly as
before, so an unloaded, version-drifted, or exited Pi session is loud
immediately and a cycle the extension never restores is loud once the beacon
passes grace. The queued-wake warning, the PID-strict turn-end guard, and
every other primary's detection are untouched.

Fold session-start's duplicate Pi marker predicate into the shared library so
the ownership contract has one owner.

* no-mistakes(document): Document Pi watcher hand-off supervision

* feat: support Cursor Agent CLI as a primary harness (#2305)

* feat(cursor): add Cursor Agent CLI primary hooks, park supervision, and session start

Register a tracked project-scope .cursor/hooks.json for Cursor's stop,
sessionStart, preCompact, and preToolUse steps.

bin/fm-turnend-guard-cursor.sh owns Cursor's turn boundary as a park: it
foregrounds the watcher arm, holds the boundary open until an actionable close,
and returns that wake as one follow-up. Exit 2 is a silent no-op on Cursor's
stop step, so the adapter never uses it. The follow-up loop is bounded twice,
by Cursor's own loop_limit and by the payload's loop_count.

bin/fm-sessionstart-cursor.sh delivers the digest as additional_context at
sessionStart, and stages it for the next turn boundary at preCompact, which
cannot inject context.

Cursor also loads the tracked Claude settings, so bin/fm-hook-host-lib.sh lets
each tracked Claude-shaped entrypoint stand down on a Cursor-delivered payload
rather than running every covered event twice.

bin/fm-tmux-lib.sh reclassifies a Cursor pane's composer cursorlessly, because
Cursor parks its terminal cursor outside the composer, which restores a genuine
composer-empty proof and unblocks away-mode escalation delivery.

* feat(cursor): make Cursor Agent CLI a verified primary harness

Resolve Cursor in the session-lock ancestry through bin/fm-cursor-lib.sh, which
a Cursor primary needs before it can hold its own home lock, and classify its
stop-hook park under the autoarm supervision model so the mid-turn pull guard
stops reporting a healthy between-turns watcher as down.

Read a Cursor pane's composer cursorlessly on tmux, gated on Cursor's own
structural process identity, which restores a genuine composer-empty proof and
lets away-mode escalations reach a Cursor primary with no daemon change.

Lift the secondmate refusals in bin/fm-spawn.sh and bin/fm-control-lib.sh now
that the supervision protocol exists and is recorded.

Cover the whole surface with a portable regression over real processes, an
opt-in live guard against the installed cursor-agent, and dated per-harness
evidence.

* docs(cursor): record Cursor as a verified primary across the owning surfaces

Update the turn-end guard, session-start, arm-seatbelt, cd-guard, watcher
continuity, architecture, configuration, README, and harness-adapters owners,
and add dated live evidence to the supervision and runtime-backend verification
records. Correct the recorded Cursor tmux composer verdict: the cursor-anchored
read is still blind, but the composite reader is no longer unknown.

Lift the remaining remote-secondmate refusal missed in the previous commit, and
add the new libs to the existing fixtures that copy a fixed dependency list.

* refactor(cursor): name the park's stand-down condition for both its causes

Also record that Cursor's preCompact firing itself is not yet live-verified,
while the static evidence that it cannot inject context, and the staging path
that follows from it, both are.

* test: give the pretool fixtures their new dependency and one lint owner

The cd-guard fixture copies a fixed dependency list and now needs the shared
hook-host predicate. Both pretool suites also asserted cleanliness with a bare
shellcheck call, a second and weaker copy of the lint definition that
bin/fm-lint.sh owns: it omits --external-sources, so it failed the moment these
checkers sourced a shared library. They now delegate to that owner.

* test: assert the cursor secondmate contract instead of its removed refusal

A cursor secondmate now launches, so the suite asserts what its park actually
needs: --trust so the home's project hooks load at all, its own home pinned as
the workspace, and the autoarm supervision model inherited across the launch.

* no-mistakes(document): Update Cursor primary documentation

* revert(cursor): cut preCompact staging from this change

Carrying a compaction digest across two concurrently running stop hooks kept
producing races that could deliver it twice or strand it indefinitely, and
closing them kept enlarging a critical section inside a hook Cursor awaits at
the turn boundary. Native preCompact firing was never observed either, so the
surface has no empirical basis yet.

Remove the adapter, its registration, its staged path in the park, and its
tests, and record the surface as deferred and uncovered alongside the Codex
interactive TUI. A regression now asserts preCompact stays unregistered so it
cannot return without its own design and evidence.

This change ships the proven core only: the turn-end follow-up park, the
run-tier session start, and away-mode delivery.

* feat(bin): add decline and repair paths for decision holds (#2330)

* feat(bin): add unrouted close paths to the captain decision gate

A captain who declines a held decision leaves no follow-up work to route,
so `resolve` could not express that answer: it requires at least one
`--routed-to` task. The only way to close such a hold was a direct
`tasks-axi done`, which never writes the durable resolution record the
completion gate reads, so the originating investigation could no longer
pass `verify` and its cleanup stayed blocked.

Add two close paths that route no work:

- `decline` closes an actively held hold with a recorded captain decision
  and no routed task. It refuses while any task is still blocked by the
  hold, because releasing routed work without recording it is `resolve`'s
  job.
- `repair` records the missing resolution block on a hold that was already
  closed outside this script. It never reopens a hold and never clears a
  dependency edge, and it refuses a hold that is still actively held.

Both require a non-empty captain decision file and share `resolve`'s
digest-based retry identity, so an exact retry is idempotent while a
changed decision is rejected. The recorded body now also names which path
closed the hold, and each routed entry regains its own line.

The gate itself is unchanged: an unanswered decision still fails
completion and blocks teardown, and neither new path can close a hold
without the captain's recorded word.

* fix(bin): require captain-hold provenance before repairing a decision

`repair` checked only that the backlog item was kind captain and Done, so
an ordinary captain-kind task that was never held for the captain could be
closed, repaired, and then pass the completion gate.

tasks-axi keeps `hold_kind` through a close, so it is the surviving proof
that an identity really was a captain hold. Require it before writing the
resolution record, and cover the case in the gate regression.

* fix(bin): surface buried wake status lines once (#2331)

* feat: add max Calm presentation level (#2334)

* feat(calm): add a max presentation level that hides mid-turn working notes

Calm's home-local preference becomes a three-state level instead of a
boolean: "off" is stock Pi, "on" is today's Calm, and "max" is Calm plus
hiding the assistant text of messages the model did not end its response
with. `/calm max` selects it from any state, a plain `/calm` steps max
back to ordinary Calm and otherwise keeps the existing on/off cycle, and
any other argument keeps that cycle too.

`config/calm` now persists "max" as its own literal value, so a session
start, resume, fork, or reload restores the stored level rather than
treating it as unrecognized and dropping to off.

The hide rule keys on Pi's intrinsic per-message stopReason: "toolUse",
or "length" with tool calls present. Streaming ("pending") text is never
filtered, because suppressing it would also stop a genuine reply from
streaming. The existing assistant layout adapter filters the blocks out
of the same shallow presentation copy it already uses for collapsed
thinking, so the message, model context, session storage, /export, and
delivery are untouched and a hidden mid-turn row collapses to zero
height. The new "assistant-working-note" class keeps that choice in the
visibility policy owner, where ordinary Calm keeps it visible.

* no-mistakes(document): Clarify Calm max persistence and taxonomy

* feat(calm): hide mid-turn working notes by default (#2339)

* feat(calm): make hiding mid-turn working notes the ordinary Calm state

Calm collapses back to the two-state on/off toggle it was before the max
presentation level, with max's hide rule promoted into ordinary Calm.
Calm on now hides mid-turn assistant working notes in addition to what it
already hid, and the /calm command parses no argument again.

The hide rule itself is unchanged: assistant text is removed from the
shallow presentation copy when the message's own stopReason is "toolUse",
or "length" with tool calls present. Streaming ("pending") text is never
filtered, so a genuine reply still streams. The message, model context,
session storage, /export, and delivery remain untouched.

config/calm persists only "on" and "off" again, but the reader still maps
a persisted "max" to on so a home upgraded from the removed level keeps
Calm on instead of dropping to off.

The mid-turn hide is now default behavior rather than an opt-in level, so
docs/calm.md documents it for users, docs/configuration.md records the
two written values plus the legacy max mapping, and the feasibility
taxonomy drops its level-scoped wording.

+  Agent-only procedure for operating Firstmate from a permanent personal-fork main.
+  Use before configuring or reversing Firstmate code remotes, briefing a Firstmate divergence topic, provisioning or using the isolated fork validation registration, integrating or discarding a divergence, responding to UPSTREAM_SYNC output or an upstream-integration required/failed result, preparing an upstream merge, re-justifying its conflicts, or deciding what the fork still carries.

+
+# fork-main-integration
+
+Load this procedure only when the Firstmate code repository itself uses permanent fork-main integration.
+[`docs/fork-main.md`](../../../docs/fork-main.md) is the operator-current owner of the mechanics, the manifest schema, and the health criteria.
+The script headers own exact mechanics and arguments.
+This file keeps what binds you at the point of action - the prohibitions, the order of operations, and the judgements no report can make for you - and points at that owner for everything descriptive.
+
+## Safety boundaries
+
+- `origin` is the personal fork and `upstream` is official.
+- Never migrate the captain's operating checkout as a side effect.
+  Run `bin/fm-fork-remotes.sh plan`, show the reverse command, and obtain concrete captain confirmation before the live `apply` command.
+- Never reconfigure the ordinary no-mistakes registration to target fork main.
+- Normal live-home remote migration must prove that registration before and after the Git change.
+  The `--no-registration` exception belongs only to provisioned remote code roots that never validate changes, and is never a retry or bypass after a registration error.
+- Provision a separate private integration clone only through `bin/fm-fork-integration.sh`.
+  Stop if ordinary-registration isolation cannot be proven before and after init.
+- Never restart or update the shared no-mistakes service from this workflow.
+- Live homes remain fast-forward-only consumers of validated fork main.
+  Real upstream and topic merges happen only in isolated candidates.
+- Keep `rerere.autoupdate=false`.
+  A replayed resolution must remain unstaged and reviewable.
+- Never force-push or rewrite a published topic or pull-request branch.
+- Never habitually merge upstream or fork main into a divergence topic.
+  Do so only for a concrete API dependency, a real merge conflict, or an upstream maintainer request.
+- Every fork-main PR still requires the captain's explicit merge approval.
+
+## New divergence intake
+
+1. Scaffold the Firstmate ship brief with `--start-ref upstream/main` so unrelated fork divergences cannot enter the upstream pull request.
+   That generated brief loads this procedure for the worker and directly carries the no-rewrite, no-routine-merge, and official-upstream validation rules through the typed launch input.
+2. Run the ordinary no-mistakes path against the official-upstream registration.
+3. Preserve the upstream pull request as the delivery and review artifact.
+4. Before fork integration, ensure the canonical `fm/divergence/<id>` topic contains one aggregate non-merge patch commit relative to upstream.
+   `git cherry` is patch-by-patch and cannot prove that a multi-commit topic equals one upstream squash commit.
+5. Never rewrite a published multi-commit PR branch to satisfy step 4.
+   Create a fresh one-commit canonical divergence topic and retain the original head as the manifest-linked delivery artifact.
+6. Create an isolated candidate from fetched fork main in the private integration clone.
+7. Run `bin/fm-fork-topic.sh integrate` with a concrete retirement condition and complete path list.
+   On exit 3, settle the retain decision, resolve and stage the product conflict, and run receipt-bound `bin/fm-fork-topic.sh continue` with the complete decision file.
+8. Drive no-mistakes from that integration clone, run health against the post-pipeline head, open the fork-main PR, and require fork CI green.
+9. Tell the captain the full fork PR URL and concise local outcome.
+10. Merge only after the captain says so, using the regular merge method so the inner topic merge remains reachable.
+11. Run `/updatefirstmate` after landing so safe homes fast-forward from validated fork main.
+
+A vague retirement reminder is not a valid manifest condition.
+Use a falsifiable statement such as "Upstream ships equivalent endpoint identity validation" or "This compatibility path is no longer reachable on every supported backend".
+
+## Upstream review disposition
+
+A pending divergence whose PR closes without merge must not remain pending.
+Choose one of two outcomes in the next validated fork integration:
+
+- Reclassify it to `rejected-but-retained` through `bin/fm-fork-topic.sh disposition` because current evidence still justifies the behavior.
+- Discard it because its retirement condition is true or the evidence no longer supports carrying it.
+
+Upstream rejection does not automatically remove useful running behavior.
+A correctness or security finding that applies locally is stronger evidence than the earlier green run and requires an immediate fix or discard.
+
+## Upstream integration
+
+Handle `UPSTREAM_SYNC: required` or `upstream-integration: required` as work for the main primary, never a secondmate or remote code root.
+Coalesce duplicate notifications behind one open integration task.
+
+`UPSTREAM_SYNC: fork topology is not validated: <requirement>` is a different problem and never starts a merge.
+This home has an `upstream` remote but has not completed the explicit migration, so the upstream movement probe was skipped and the line repeats on every startup until it is fixed.
+Report the named requirement to the captain and, once they confirm, complete the migration through `plan` then the live `apply` command, or reverse it - never migrate `origin` silently to clear the line.
+
+1. Ensure the private fork registration passes `bin/fm-fork-integration.sh check`.
+2. Create an isolated candidate branch at fetched `origin/main` from the private integration clone.
+3. Run `bin/fm-fork-merge.sh prepare`.
+4. On a clean result, inspect the emitted `git range-diff --remerge-diff` review and health result before starting no-mistakes.
+5. On exit 3, treat every named conflict as a divergence re-justification decision before resolving files.
+6. Load `ask-user-authority` before deciding whether routine authority can answer a re-justification.
+   A material behavior expansion, destructive choice, security-sensitive choice, or captain-owned product trade-off still goes to the captain.
+7. Resolve files only after the decision is settled, write the complete `firstmate.fork-rejustify.v1` decision file outside the candidate working tree, and run `continue`.
+   If the settled decision is complete removal, use the receipt-bound upstream `abort`, then the independent topic `discard` path, land that candidate, and retry upstream preparation instead of continuing the conflict.
+8. Drive no-mistakes through the private fork registration and process every gate.
+9. Require fork CI green and captain merge approval.
+10. Use the regular merge method, then run `/updatefirstmate`.
+
+A replayed rerere result supplies only the previously accepted file resolution, never the answer to whether the divergence is still worth carrying; the unmerged index is the barrier that keeps that decision explicit, so never let a replay stand in for it.
+
+## Health and relevance
+
+Use `bin/fm-fork-status.sh` for the local answer and add `--refresh` only when live remote and PR evidence is needed.
+After no-mistakes, use the post-pipeline candidate command in [`docs/fork-main.md`](../../../docs/fork-main.md); a bare invocation reads the fork remote rather than proving candidate `HEAD`.
+Its own errors, signals, and exit status are the machine verdict, and [`docs/fork-main.md`](../../../docs/fork-main.md) states how it classifies raw `git cherry` facts and what makes it unhealthy.
+
+Never describe the fork as healthy when that report is not.
+The one judgement the report cannot make is yours: a pending unit that is aging without action is not a healthy fork, however clean the machine verdict.
+
+Run the `git range-diff --remerge-diff` command the report prints for every unit the latest upstream merge touched.
+It is a human review surface, not machine state.
+
+## Discard
+
+Prepare discard only from an isolated branch at fetched fork main:
+
+```sh
+bin/fm-fork-topic.sh discard --id <id> --repo <isolated-worktree>
+```
+
+Any product-file conflict reopens re-justification and leaves a receipt-bound merge or revert operation.
+Resolve the decision and files, write the complete `firstmate.fork-rejustify.v1` decision outside the candidate, then run `bin/fm-fork-topic.sh continue --decisions <file> --repo <isolated-worktree>`.
+Validate the actual post-pipeline candidate through the private fork registration and require captain approval for its fork-main PR.
+Never reset or rewrite fork main to remove a divergence.
+
+Git remembers a reverted merge as unwanted ancestry.
+To restore discarded behavior, revert the revert or introduce a genuinely new topic version.
+Do not merge the old topic blindly.

+The primary integrations for `claude`, `codex`, `opencode`, `pi`, `pi-signed`, `grok`, and `cursor` have empirically validated hook paths for the "no turn ends blind" guard.
 `claude` and `codex` block directly through Stop hooks that preserve exit status 2 and stderr from `bin/fm-turnend-guard.sh`.
 `opencode`, `pi`, and `pi-signed` expose passive lifecycle callbacks and force one bounded follow-up when the shared predicate blocks.
 Grok selects native blocking or its pre-native bounded resume fallback from the exact running Stop payload; [`docs/turnend-guard.md`](../../../docs/turnend-guard.md) owns that contract.
 Kimi is outside the primary turn-end guard scope, while `docs/turnend-guard.md` owns its separate guarded global hook for crew wake signals.
 muse is CREWMATE/SCOUT ONLY and has no primary integration at all: its plugin engine (its only hook surface) is disabled in the default build, and its Claude-compatible hook dialect names `asyncRewake` and model reawakening as explicitly unsupported, which is exactly what a firstmate primary's turn-end supervision needs.
 `bin/fm-spawn.sh` refuses a `--secondmate` launch on muse for that reason.
+cursor HAS a full hooks system: 20 lifecycle events configurable at project scope in `.cursor/hooks.json`, plus a Claude-Code compatibility name map that also loads `<project>/.claude/settings.json`.
+Its `stop` step cannot block - exit 2 there is a silent no-op - so `bin/fm-turnend-guard-cursor.sh` parks the turn boundary on the watcher and returns one bounded `followup_message` instead.
+Because Cursor loads the tracked Claude settings too, every Claude-shaped entrypoint whose event Cursor covers stands down on a Cursor-delivered payload.

+
+Cursor Agent CLI runs crewmate, scout, secondmate, and primary work.
+Its primary supervision is the stop-hook park in [`docs/supervision-protocols/cursor.md`](../../../docs/supervision-protocols/cursor.md), registered in tracked `.cursor/hooks.json`; a Cursor primary or secondmate must be launched with `--trust` or no project hook loads at all.
+Do not confuse `harness=cursor` using a `cursor-grok-4.5-*` model with `harness=grok`, which is the separate xAI Grok Build CLI and credential surface.
+
+| Fact | Value |
+|---|---|
+| Binary | Resolved through `fm_cursor_resolve_binary` (bin/fm-cursor-lib.sh). `cursor` is NOT the CLI: the installed names are `cursor-agent` and the legacy alias `agent`, both symlinked into `~/.local/share/cursor-agent/versions/<version>/cursor-agent`. The STABLE launcher is used, never the versioned target, which the CLI replaces on its own auto-update. |
+| Launch | A positional prompt with `--trust`, `--yolo`, `--model <model>` when selected, and `--workspace <absolute-task-worktree>`, behind `env -u` of the foreign primary markers. |
+| Models | Validate against `cursor-agent --list-models` for the current account rather than a fixed list; that list has already drifted once. The live catalog contains only `-high` Grok ids (`cursor-grok-4.5-high`, `cursor-grok-4.5-high-fast`) and several `xhigh` ids, so an assumed low/medium Grok id is invalid. |
+| Busy state | Its own per-conversation transcript, folded on demand by `bin/fm-busy-lib.sh` (source `cursor-transcript`). Each turn is bracketed by a `role:user` open and a typed `turn_ended` close covering `success` and `aborted`, so unlike Claude's `Stop` hook this source covers manual interruption. Nothing is armed and no record is ever seeded. Backend-agnostic, and confirmed identical on tmux and Herdr. |
+| Exit command | `/exit` |
+| Interrupt | Single Escape. The composer returns to its placeholder rather than the cancelled prompt, so NO clear key is needed (unlike muse). `bin/fm-control-lib.sh` claims no cancellation acknowledgement: the aborted transcript close appeared within seconds in some runs and not within twenty in others. |
+| Skill invocation | `/<skill>`, for example `/no-mistakes`. Cursor discovers firstmate's user-level skills; `/no-mistakes` autocompleted with firstmate's own description and invoked the skill. |
+| Slash submission | The popup is REAL and swallows the first Enter: the first closes the popup and a SECOND submits, the same hazard as grok. The submit core's retried Enter covers it. |
+| Autonomy | `--yolo`, the documented alias for `--force`, whose TUI footer reads `Run Everything`. |
+| Trust dialog | `--trust` suppresses it. `--yolo` does NOT, and every task gets a fresh worktree path, so without `--trust` every spawn would block on it. |
+| Environment marker | `CURSOR_INVOKED_AS=cursor-agent` on the agent process and its children, plus `CURSOR_AGENT=1` on child/tool processes. Other `CURSOR_*` endpoint and credential variables are not identity markers. |
+| Effort | No effort flag exists. The requested axis is recorded in task metadata and never reaches the launch command. |
+| Composer | A BARE row whose prompt glyph is `→` (U+2192); no border. Idle placeholders are `Plan, search, build anything` fresh and `Add a follow-up` after a turn, drawn de-emphasised so a styled capture separates them from real typed text. |
+| Primary hooks | Tracked project-scope `.cursor/hooks.json` registers `stop`, `sessionStart`, and two `preToolUse` seatbelts, all anchored through `$CURSOR_PROJECT_DIR`. Cursor ALSO loads `<project>/.claude/settings.json`, so the tracked Claude entries stand down on a Cursor-delivered payload; `docs/turnend-guard.md` owns that predicate. |
+| Primary limits | `stop` does not fire in headless `cursor-agent -p`. `preCompact` is deliberately unregistered because it cannot inject context, so a Cursor primary does not re-emit its digest after a compaction; that surface is deferred to a follow-up. Project hooks need `--trust`. |
+
+**Detection ordering is load-bearing.**
+Cursor does NOT clear an inherited `CLAUDECODE`, so a cursor worker under a claude primary carries both markers and whichever is tested first wins.
+`bin/fm-harness.sh` tests the cursor markers BEFORE the `CLAUDECODE` check, and the launch additionally clears the foreign markers.
+Both are kept: launch sanitization only covers sessions fm-spawn started, while the ordering also covers a cursor session a human started by hand.
+
+**The `node` process-name caveat.**
+Cursor runs as a bundled node script, so tmux reports `#{pane_current_command}` as a bare `node` while `ps -o comm=` carries the cursor-agent install path.
+`node` matches no harness name pattern, so identity comes from Cursor's own name or install tree in the path or argv[0] (`bin/fm-cursor-lib.sh`).
+An unrelated `node` or `agent` is deliberately left `other`, which the liveness callers fold into `ambiguous` rather than `dead`.
+Because the versioned install path is what identifies the alias, an auto-update changes the resolved target but not the identity rule.
+
+**Cursor parks its terminal cursor outside its composer.**
+`#{cursor_y}` pointed below the footer both when idle and with real text typed, and `#{cursor_flag}` was 0, so tmux's cursor row is not a composer locator for a Cursor pane and the cursor-ANCHORED read answers `unknown` in every state.
+`bin/fm-tmux-lib.sh` therefore reclassifies a pane it can prove is Cursor the way every cursorless backend already classifies it, letting the bottom-most shape win, so the composite `fm_tmux_composer_state` now reports a real `empty` or `pending` for a Cursor pane on tmux (verified 2026-08-13).
+That gate is Cursor's own structural process identity from `bin/fm-cursor-lib.sh`, never the verdict alone, so the strict blank-cursor-row posture stays in force for every other harness and a dead shell still never reads `empty`.
+This is what makes away-mode escalation delivery work against a Cursor primary: `bin/fm-supervise-daemon.sh` needs an affirmatively-empty composer before it types, and it needed no Cursor-specific branch once the reader was correct.
+Submission is additionally acknowledged from the idle-to-busy transition, which is why cursor's `ctrl+c to stop` token is part of the delivery busy union in `bin/fm-composer-lib.sh`.
+Match that TOKEN and never the spinner verb: the same version rendered `Working` in one turn and `Running` in the next.
+
+**Delivery confirmation is verified on tmux and Herdr only.**
+Herdr reports a Cursor pane `blocked` in EVERY state - idle, mid-turn, and after - so its native idle-baseline submit path is unreachable for Cursor and the composer branch runs instead; that branch reads a mid-turn row carrying the placeholder beside `ctrl+c to stop`, which is `pending`.
+`bin/backends/herdr.sh` therefore confirms a Cursor submit from a rendered-footer idle-to-busy transition, taking the baseline before the first Enter so an already-busy pane never confirms.
+Zellij, cmux, and Orca share a submit core that never consults that footer, so a Cursor steer there LANDS but `bin/fm-send.sh` reports delivery unconfirmed and exits non-zero.
+Treat that as a known limitation of those three backends rather than a lost message: the steer is in the pane and the worker's own recorded state still comes from its transcript fold.
+Teaching the shared core the same transition is deliberately separate work, because it changes the submit path for every harness on those three backends and needs its own live validation on each.
+
+The composer's reverse-video placeholder remnant is taught to the ONE fleet-wide screen classifier in `bin/fm-composer-lib.sh`, not to any adapter.
+Herdr additionally draws the composer's rules with half-block glyphs, which the same shared classifier owns as structural edges; without them a bare composer's wrap region swallows the footer below it and an idle pane reads `pending`.
+`docs/verification/runtime-backends.md` "Cursor Agent CLI" owns the dated captures, and the drift guard that refreshes them is:
+
+```bash
+FM_HARNESS_LIVENESS_DRIFT=1 bin/fm-test-run.sh tests/fm-harness-liveness-drift-live-e2e.test.sh
+```
+
+Firstmate acquires and enters the treehouse worktree before launching Cursor, then passes that same absolute path through `--workspace`.
+NEVER pass Cursor's own `-w/--worktree`: it allocates a SECOND worktree under `~/.cursor/worktrees` and would break firstmate's worktree-isolation contract.
+The raw CLI accepts repeatable `--add-dir <path>` for deliberate multi-root workspaces; the adapter adds none, and the brief rides inline as the positional prompt, so the private brief directory needs no grant.
+
+Spawn a Cursor scout with an explicit model:
+
+```bash
+bin/fm-spawn.sh <task-id> <project> --scout --harness cursor --model cursor-grok-4.5-high
+```

-1. Propose.
-   The sweep appends a `proposed-offload` section to the completion receipt: each candidate's first line, source file, estimated tokens, the one-line trigger, the proposed destination as a freeform skill name plus draft description line or a project plus file, the privacy and visibility verdict, and the expected budget relief.
-   The same list is the body of a single durable captain-held backlog item, created on first use with `tasks-axi add <id> <title> --kind captain --repo firstmate --body "<proposal body>"` before `tasks-axi hold <id> --reason "<reason>" --kind captain` transitions it to a hold.
-   On later passes, inspect it with `tasks-axi show <id> --full`, refresh unresolved proposals in place with `tasks-axi update <id> --body-file <path>`, preserve every candidate's recorded approval state, and keep the existing hold rather than appending or creating a duplicate.
-   The held item's body is the durable approval record, so an approved candidate remains approved and is never forgotten or proposed again.
-   If the captain never answers, nothing migrates and the held item simply persists; there is no auto-migration, ever.

 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 concurrently in a bounded worker owned by `bin/fm-startup-network.sh` and is reported in the digest's own `NETWORK CHECKS` section.

 When that section reports its checks still in progress it names exactly what is unconfirmed; treat none of those as passed until the result lands, either from `bin/fm-startup-network.sh report` or as a `check: startup-network` wake.
 
 1. **Lock** - acquires the per-home session lock first, before anything mutates shared state, then starts the deferred network 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.

    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`).
-3. **Wake queue** - when locked, presents the durable wake queue and prints the raw records prominently as this turn's first work queue; a bounded, clearly labeled historical status-event annotation may follow a valid `signal` record but never replaces it 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.

 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.

 There is no reliable way for `bin/fm-brief.sh`'s scaffold to detect that a task's repo is firstmate itself, so firstmate adds this skill's load line to firstmate-repo briefs by hand.

 # Vision
 
 `firstmate` exists so that one person can run a crew of coding agents with the leverage of a team and the accountability of a single pair of hands.
+It aims to create an experience: a sense of peacefulness, confidence that everything is under control, and an ease of mind that nothing will fall through the cracks the moment the captain looks away.
+That experience is the experience of being a good captain who sails with a well-managed crew, with a first mate that carries out the captain's direction.
 It serves the captain: an individual operator whose ambitions outrun their attention, and it turns intent stated once into delegated, supervised, evidence-backed work across every project they care about.
 It empowers exactly one individual; collaboration between humans belongs to other systems.
 It owns exactly one thing: the layer between the captain's intent and the agents that carry it out.
 
 ## One captain, one interface
 
+Without a first mate, parallel agent sessions force constant context-switching: the captain juggles a long list of sessions, relearns what each one was about and what the right next step should be, and watches coding's focus, flow, and peace replaced by non-stop tab-juggling.
+Most harnesses and orchestrator apps make it easier to see those sessions and jump between them, but the context switch remains the captain's burden.
 The captain talks to the first mate and to nobody else; every worker reports through the first mate and never addresses the captain directly.
 Captain-facing language is outcomes, consequences, and decisions; the machinery that produced them stays below deck.
 An escalation exists for a decision only a human can make; progress, retries, and internal mechanics are never news.
 The interface must stay honest under load: batching and silence are presentation choices, and never hide a failure, a decision, or a risk.
-Experience features on top of this interface are welcome only when they compose with the workflows the captain already has: opt-in, and never in the way.

 Everything that matters survives the death of any conversation: work in flight, promises made, decisions pending, and the captain's preferences live in durable records, never in chat memory.
 The fleet reconciles from disk and from live session state, so killing any session, including the first mate's own, loses nothing and surprises no one.
 Obligations are closed by records, not by recollection: a promised reply, an open decision, or a queued wake is retired only by the durable event that answers it.

-#              "Incident (2026-07-07)"): the row's TRIMMED content starts with
-#              one of the verified agent-specific prompt glyphs but carries no
-#              closing border at all - claude's own live input row is a bare
-#              "❯ …" with no surrounding │, and codex's is a bare "› …". Both
-#              harnesses ALSO render bordered decorative boxes elsewhere (a
-#              startup welcome banner, an update-available notice) that
-#              satisfy the bordered shape above; requiring a match on EITHER
-#              shape and keeping the last (bottom-most) one is what keeps the
-#              live composer winning over a stale decorative box still sitting
-#              in the same capture window - a bordered box is only ever
-#              followed later on screen by the actual live composer, never the
-#              reverse, in every harness observed so far. The bare shape is
-#              deliberately narrower than the bordered content classifier so a
-#              no-agent shell fallback prompt (`>`, `$`, `%`, or `#`) falls
-#              through to `unknown` instead of being misread as delivered.
-#   separated - Pi's composer is one or more content rows between two solid
-#              horizontal `─` separator rows, with no prompt glyph or side
-#              borders. This shape is accepted ONLY when Herdr's native
-#              `agent get` identifies the target as Pi and reports it idle,
-#              done, or blocked. A missing/stale/non-Pi agent identity, a
-#              working Pi, an over-tall candidate, or an incomplete separator
-#              pair remains unknown. This identity + structure conjunction is
-#              what makes a blank Pi row safe without weakening dead-shell or
-#              ambiguous-pane refusal.

-#   empty   - blank, a bare prompt glyph, known ghost/placeholder text
-#             ("Type a message...", verified grok 0.2.82's empty-composer
-#             placeholder), or only de-emphasised ANSI ghost/placeholder text
-#             recognized by the shared fm_composer_strip_ghost extractor
-#             (dim/faint or dark-TRUECOLOR foreground). Safe to treat as
-#             submitted.
-#   pending - real, unsubmitted text sits in the composer. This deliberately
-#             also covers a slash-command popup that just closed but only
-#             auto-completed or filled an argument-hint placeholder into the
-#             composer (e.g. "/compact" -> "/compact compaction
-#             instructions", verified live against real grok 0.2.82) - that

+# --- unread status lines since the presentation cursor ----------------------
+#
+# The drain annotation historically printed only the newest status line, so a
+# substantive `note:` answer immediately followed by a routine `note:` (or a
+# pending-reply resolution buried under a later unrelated append) never reached
+# the supervisor. Those verbs also never enter the OPEN DECISIONS fold, so they
+# had no other surfacing path.
+# These helpers are the ONE owner of "what is still unread since the last drain
+# presentation": one fleet manifest records each status identity and last-
+# presented byte offset, and one atomic replacement commits only the contiguous
+# status spans that were successfully presented. A quiet fleet scan leaves
+# routine working/done bytes unacknowledged so a subsequently published signal
+# can still annotate them. A missing manifest row or changed file identity is
+# offset 0 for the current file, while malformed or unreadable cursor state
+# aborts presentation without advancing any offset. A trusted cursor at EOF
+# prints nothing, so already-presented bytes are not replayed as new. Teardown
+# retires a task's manifest row with its status file, so reusing a task ID starts
+# the replacement log unread at byte 0. Informational `note:` lines and
+# reserved-key pending-reply resolutions are the fleet-wide unread surface;
+# they are not open decisions and are not persisted in the folded open-set.
+
+# Read the legacy per-task open-decisions cursor used to seed the presentation
+# offset before the fleet manifest exists. A fold-version mismatch, identity
+# mismatch, or offset past the current size falls back to 0. Never writes unless

-# bin/fm-composer-lib.sh - the ONE fleet-wide owner of composer-content
-# classification, shared by every session-provider adapter: the tmux path
-# through bin/fm-tmux-lib.sh, and bin/backends/{herdr,orca,cmux}.sh directly.
+# bin/fm-composer-lib.sh - the ONE fleet-wide owner of composer classification:
+# every shape a verified harness draws, every glyph, every container proof, and
+# the empty|pending|pending-unproven|unknown verdict, shared by every
+# session-provider adapter (tmux via bin/fm-tmux-lib.sh, and
+# bin/backends/{herdr,orca,cmux,zellij}.sh) and by fm-spawn.sh's kimi
+# launch-readiness check.
 #
-# WHY THIS EXISTS (task fm-composer-shellglyph-safety): the four adapters each
-# carried their own copy of the "is this composer row empty / pending / not an
-# agent composer" decision, and the copies drifted. The dangerous drift: a BARE
-# shell prompt glyph (`>`, `$`, `%`, `#`) - what a pane shows once its agent has
-# exited to a plain login shell - was treated as an empty, ready-to-inject
-# AGENT composer. The away-mode escalation injector (bin/fm-supervise-daemon.sh)
-# reads composer-emptiness to decide whether a pane is a safe injection target,
-# so a dead-shell pane misread as "empty" meant an escalation could be typed
-# into (and, worst case, executed by) that shell. Consolidating the one decision
-# here means the safety rule cannot silently drift across adapters again.
+# WHY THIS EXISTS (tasks fm-composer-shellglyph-safety and
+# fm-composer-thin-adapter-refactor-r1): the adapters each carried their own
+# copy of composer shape knowledge, and every copy drifted. The audited result
+# (data/fm-composer-consolidation-audit-s1) was a 5-adapter x 6-harness matrix
+# in which no adapter was right about more than five harnesses, no two adapters
+# were wrong in the same places, and one harness was unreadable everywhere.
+# The consolidation rule that prevents a recurrence: an adapter CAPTURES a
+# screen and DESCRIBES its capabilities; it never classifies. A new harness
+# shape is taught to fm_composer_classify_screen below, once, and every backend
+# that can capture a screen learns it in the same commit.
 #
-# THE SAFETY RULE this owner enforces: a bare shell prompt glyph is a genuine
-# empty agent composer ONLY when it appears INSIDE a real agent-composer
-# container - a bordered composer box, where the harness draws its own prompt
-# glyph (e.g. claude's older `| > ... |`). On a bare, unstructured row it is a
-# dead-shell prompt and is NEVER "empty"; it classifies as `unknown` (not a safe
-# injection target). The AGENT prompt glyphs `❯` (claude), `›` (codex), and
-# `⟩` (U+27E9, muse) are a genuine empty agent composer either way, bordered or
-# bare. Every agent glyph must be listed in ALL THREE places below - the
-# ghost-stripped-to-empty fallback, the bare-row case, and the leading-glyph
-# strip - because a glyph present in only some of them classifies inconsistently
-# depending on how its harness happens to colour the row.
+# THE CAPABILITY MODEL: adapters differ in what their capture primitive can
+# see, and those differences enter here as DATA (the <caps> argument), never as
+# adapter code. Capability differences change how CONFIDENTLY a shape can be
+# judged; they never change what the shapes ARE:
+#   styled=1    the capture preserves ANSI styling, so ghost/placeholder text
+#               is detectable and can be stripped (tmux -e, herdr --format
+#               ansi, zellij dump-screen --ansi). With styled=0 (cmux, orca)
+#               ghost text is unreadable, so a bare glyph row or left-bar row
+#               carrying trailing non-idle text degrades to `unknown` rather
+#               than `pending`: the text may be the harness's own idle
+#               suggestion, and a false `pending` blocks every safe caller.
+#   cursor=1    a cursor row is supplied (tmux #{cursor_y} only). The cursor
+#               anchors shape selection: the shape containing the cursor is the
+#               composer. Without it, the bottom-most shape wins.
+#   identity=1  a native agent identity/state probe exists (herdr `agent get`;
+#               the tmux pi foreground-process probe). Identity is what makes
+#               Pi's blank separated composer provable; with identity=0 that
+#               shape stays `unknown`.
+#   rows=<n>    the capture's bounded row count (informational).
 #
-# GHOST/PLACEHOLDER TEXT is the other half of this owner (task
-# afk-herdr-false-pending): a harness fills an otherwise-empty composer with
-# de-emphasized ghost text - claude's rotating prompt suggestion, codex's idle
-# suggestion, grok's placeholder - which a plain capture cannot tell apart from
-# text a human typed, so the away-mode injector reads the idle pane as "pending
-# input" and defers every escalation (the overnight wedge that motivated this
-# consolidation). fm_composer_strip_ghost is the ONE ANSI-aware extractor of
-# "real typed content": it drops every de-emphasized run - dim/faint (SGR 2, how
-# claude and codex render ghost text) AND a dark/muted TRUECOLOR foreground (how
-# grok renders placeholder/hint text) - and keeps only normal-intensity,
-# normally-coloured text. Consolidating it here means the two ANSI-capable
-# adapters (tmux via bin/fm-tmux-lib.sh, herdr via bin/backends/herdr.sh) cannot
-# drift into per-harness one-off strips again; the previous herdr-only faint
-# byte-pattern check missed claude's own dim ghost (its prompt glyph is not
-# bold-wrapped) and no adapter covered grok's truecolor placeholder at all.
+# THE STRICT BLANK-ROW RULE (captain decision blank-row-injection-posture,
+# 2026-08-09): a blank or otherwise unidentified input row with no positive
+# container proof is `unknown` and callers defer. This replaced tmux's
+# permissive "blank cursor row = empty = safe to inject" rule fleet-wide: a
+# blank row under the cursor can be a modal dialog, a dead shell between
+# transcript rules, or a mid-redraw pane, and the away-mode injector types
+# escalations into whatever it calls empty. Positive container proof means one
+# of the shapes in the catalogue below.
 #
-# Each adapter still owns its own CAPTURE and structural row-finding, because
-# those use genuinely different primitives (tmux's visible-pane box scan,
-# herdr's ANSI tail scan, orca/cmux's plain read-screen). Once an adapter has a
-# candidate composer row it hands the RAW styled row to
-# fm_composer_strip_ghost for the real-typed-content extraction, strips the box
-# borders, trims, and hands the result plus a <bordered> flag to
-# fm_composer_classify_content for the shared
-# empty|pending|unknown verdict. orca/cmux read a plain (unstyled) screen so
-# they have no ghost styling to strip and rely on the idle-placeholder match
-# below. Re-sourcing is a cheap idempotent redefinition, so this file needs no
+# THE SHAPE CATALOGUE (all verified against real harnesses; byte-level
+# captures in data/fm-composer-consolidation-audit-s1/report.md and

+#   bordered   - a complete boxed composer: a top border, side-bordered content
+#                rows of the same family, and a bottom border (grok, kimi,
+#                older claude). The bottom border may carry a TITLE (grok
+#                writes its model name there); a titled bottom border that
+#                still starts and ends with the family's rule glyph is
+#                tolerated, not ambiguity.
+#   bare       - an agent prompt glyph row with no border at all (claude `❯`,
+#                codex `›`, muse `⟩`, cursor `→`). The agent glyph is itself the container
+#                proof; a bare SHELL glyph (`>` `$` `%` `#`) never is.
+#   left-bar   - opencode: rows prefixed by a heavy left bar `┃` with no
+#                closing border, holding the idle hint, blank rows, and a
+#                mode/model footer line.
+#   separated  - pi: content rows between two solid horizontal `─` rules, no
+#                glyph and no side border. Provable only with a live agent
+#                identity reporting an idle/done/blocked pi (herdr `agent
+#                get`; the tmux foreground-process probe), because a blank
+#                region between two transcript rules is otherwise exactly the
+#                strict rule's unidentifiable blank row.
+#
+# THE SAFETY RULE for glyphs: a bare shell prompt glyph (`>` `$` `%` `#`) -
+# what a pane shows once its agent has exited to a plain login shell - is a
+# genuine empty agent composer ONLY inside a bordered container. On a bare row
+# it is a dead-shell prompt and classifies `unknown` (never a safe injection
+# target). The AGENT glyphs `❯` (claude), `›` (codex), `⟩` (U+27E9, muse),

+# UNICODE WHITESPACE (issue #1988; open PRs #1995/#2047 target the same
+# defect and #1995's naming is adopted here so the implementations converge):
+# a harness may separate its prompt glyph from composer content with a
+# non-ASCII space. Real claude 2.x draws its EMPTY composer as exactly `❯`
+# followed by U+00A0 NO-BREAK SPACE. POSIX `[[:space:]]` includes U+00A0 only

+# pane read `empty` under a UTF-8 shell and `pending` under LC_ALL=C (a
+# daemon, launchd, or ssh context), deferring every away-mode escalation.

+# Cursor executable resolution and Cursor process identity.
+# Sourced by bin/fm-spawn.sh, bin/fm-harness.sh, bin/fm-busy-lib.sh, and
+# bin/backends/tmux.sh. This file is sourced by scripts and has no side effects
+# on source.
+#
+# Why one owner: cursor ships TWO executable names - `cursor-agent`, plus the
+# legacy alias `agent` it installs on every platform. `agent` is far too
+# generic to trust on its name alone, so every spawn, ancestry, and liveness
+# caller has to agree on the same narrowed rule or an unrelated `/opt/agent`,
+# an unrelated `agent` on PATH, or a path that merely contains an `agent/`
+# directory component silently classifies as this harness. That widening would
+# let firstmate launch an unrelated executable with Cursor flags.
+#
+# Two independent kinds of Cursor evidence are accepted, and either alone
+# carries a positive verdict, so no single vendor string is load-bearing:
+#
+#   Structural (no subprocess, safe during a process scan): the canonical path
+#   is named cursor-agent or lives under Cursor's versioned install tree.
+#   Cursor's installer places both names as symlinks into
+#   ~/.local/share/cursor-agent/versions/<version>/cursor-agent (verified
+#   2026-08-11, cursor-agent 2026.08.11-e8db854), so the alias resolves to
+#   Cursor's own name and install tree.
+#
+#   Probe (a bounded `--help` run, used only when resolving an executable to
+#   launch, never during a process scan): Cursor's own CLI banner and its
+#   CURSOR_API_ENDPOINT / api2.cursor.sh option text. Fails closed on a
+#   timeout, a non-zero exit, or missing markers - a bare zero exit is never
+#   accepted as proof.
+#
+# Process detection deliberately uses the structural signal only. Probing an
+# arbitrary pid's executable during an ancestry walk or a liveness poll would
+# execute a stranger's binary, which is exactly the hazard this file exists to
+# close.
+#
+# Cursor's composer shape is deliberately NOT here. Its reverse-video
+# placeholder remnant is taught to the ONE fleet-wide screen classifier in
+# bin/fm-composer-lib.sh, which every backend already delegates to; an
+# adapter-local composer normalizer would be the second copy that owner exists

+# Eight facts are read by more than one fork script and must mean exactly the
+# same thing in each, so they live here rather than being copied:
+#   - which branch a remote's default is (origin/upstream default resolution);
+#   - which ref is a divergence's canonical topic (published fork branch first,
+#     then a local branch);
+#   - whether a manifest path spec owns an actual changed path;
+#   - what one commit's patch identity is;
+#   - which first-parent commits arrived through direct or regular PR delivery;
+#   - whether a patch can be reversed from a current tree through a private index;
+#   - how a conflict receipt binds the unaffected index;
+#   - how to read gh-axi's current one-value TOON API envelope.
+#
+# Path ownership in particular is a shared invariant between two competing
+# consumers: fm-fork-merge.sh derives the affected-unit list for a conflict
+# re-justification receipt from it, while fm-fork-status.sh decides "manifest
+# unit <id> does not cover changed path <path>" from it. Two copies could drift
+# apart and attribute a conflict to a unit the health report says does not own
+# that path, which would then demand re-justification decisions for the wrong
+# units.
+#
+# Patch identity is the same kind of shared invariant. fm-fork-merge.sh records
+# the evidence that upstream accepted a divergence, and fm-fork-status.sh
+# re-proves that recorded evidence. Both must compute the identity the same way
+# or the merge would write proof the health owner cannot verify.

+#       Require origin=<fork>, upstream=<official>, distinct URLs, main tracking
+#       origin, rerere.enabled=true, and rerere.autoupdate=false.
+#   fm-fork-remotes.sh plan <fork-url> <upstream-url> [<repo>]
+#       Read only. Validate the requested migration and print the exact apply and
+#       reverse commands. Never infers a fork owner or changes Git configuration.
+#   fm-fork-remotes.sh apply <fork-url> <upstream-url> --confirm [--no-registration] [<repo>]
+#       Migrate only an exact upstream-as-origin checkout, or validate an already
+#       migrated one. Prints the reverse command before changing anything. Both
+#       URLs must answer a read-only ls-remote preflight. The ordinary
+#       no-mistakes registration must prove official remote plus personal fork
+#       unchanged before and after migration. --no-registration is reserved for
+#       provisioned remote code roots that never validate changes themselves.
+#       Never force-pushes or changes a branch or working-tree file.
+#   fm-fork-remotes.sh reverse <fork-url> <upstream-url> --confirm [<repo>]
+#       Restore the official repository as origin and retain the personal fork as
+#       a remote named fork. Never changes commits or working-tree files.
+#   fm-fork-remotes.sh inherit <source-repo> <target-repo>
+#       Provisioning-only convergence for a new standalone secondmate clone.
+#       A linked worktree already shares the source config and is a no-op. An
+#       unrelated target remote is refused, never overwritten.
+#
+# apply/reverse require the literal --confirm token because changing origin on a
+# captain's operating checkout must be surfaced and approved, never performed as
+# a side effect of startup or self-update. The remote-root-only
+# --no-registration exception is an explicit provisioning input, not a fallback
+# after a no-mistakes error. apply explicitly leaves
+# rerere.autoupdate off: rerere may populate a repeated resolution in the working
+# tree, but it must remain unstaged for review.
+#
+# Every network call runs with GIT_TERMINAL_PROMPT=0. Remote home provisioning
+# calls apply non-interactively while holding the provision lock, so an
+# unconfigured credential helper must fail the run rather than block it on a
+# username prompt that no one can answer.

+# Report and validate the permanent fork-main divergence set.
+#
+# Usage:
+#   fm-fork-status.sh [--repo <path>] [--fork-ref <ref>] [--upstream-ref <ref>] [--refresh] [--json] [--facts-only]
+#   fm-fork-status.sh --check-upstream [--repo <path>] [--refresh]
+#
+# `git cherry upstream/<default> origin/<default>` supplies one fact only: which
+# commits have no equivalent upstream patch. The tracked fork-divergences.json
+# manifest supplies meaning: the canonical topic patches the fork intends to
+# carry, their class, pull-request disposition, retirement condition, paths, and
+# integration merges. A raw non-upstream commit outside those topics is a visible
+# signal, not automatically a carried divergence or a health failure. Descendant
+# validation fixes and manifest-only governance commits are attributed as
+# integration artifacts. retired_upstream records add the one equivalence fact
+# Git can no longer recompute after an integration merge, and every one of them
+# is re-proved here before its patch leaves the factual non-upstream count.
+#
+# --refresh fetches origin and upstream and verifies recorded GitHub PR
+# dispositions with gh-axi. Without it, the report is network-free and uses
+# local refs plus recorded dispositions. gh-axi's current API serializer is
+# parsed as one complete, untruncated scalar envelope rather than compared as
+# raw stdout.
+# --check-upstream is the cheap self-update and startup probe: it reports whether upstream is already an ancestor of the fork
+# and never merges or changes a working-tree file; --refresh still updates the
+# remote-tracking refs it reads. --facts-only keeps rising divergence count
+# visible but makes the exit status depend only on Git/manifest consistency and
+# superseded debt; candidate preparation uses it when adding or retiring an
+# already-authorized topic would otherwise make trend an inappropriate blocker.

+# Integrate, reclassify, or discard one canonical fork divergence topic in an
+# isolated fork candidate.
+#
+# Usage:
+#   fm-fork-topic.sh integrate --id <id> --summary <sentence>
+#     --class <pending|rejected-but-retained|private> --topic <ref>
+#     --retire-when <falsifiable-condition> --path <path-or-prefix>...
+#     [--pr-url <github-pr-url> --pr-disposition <open|rejected>]
+#     [--repo <isolated-worktree>]
+#   fm-fork-topic.sh disposition --id <id>
+#     --class rejected-but-retained --pr-disposition rejected
+#     [--repo <isolated-worktree>]
+#   fm-fork-topic.sh discard --id <id> [--repo <isolated-worktree>]
+#   fm-fork-topic.sh continue --decisions <json> [--repo <isolated-worktree>]
+#
+# integrate requires a clean named candidate branch at fetched origin/main and a
+# canonical topic whose `git cherry upstream/main <topic>` result contains
+# exactly one non-equivalent commit. This one-aggregate-patch invariant is what
+# makes upstream squash/rebase equivalence measurable. It merges the topic with
+# --no-ff --no-commit, writes the manifest entry into that same merge commit,
+# commits, and validates the candidate against HEAD.
+#
+# disposition is the supported governance-only pending-to-rejected transition.
+# It updates the class and recorded pull-request disposition atomically in one
+# candidate commit, then validates that actual HEAD. The commit is reported by
+# health as a manifest-governance artifact, never as a carried divergence.
+#
+# discard derives every delivered merge that integrated the named topic, whether
+# direct or in one regular pull-request candidate range, and applies their
+# mainline-parent-one inverses as one `git revert --no-commit` sequence. It
+# removes the manifest unit and commits the complete discard once, so intermediate
+# manifest states never enter history.
+#
+# A product conflict in integrate or discard exits 3, leaves Git's merge or
+# revert state intact, and writes a worktree-private receipt binding the branch,
+# original HEAD, merge or revert head, manifest, and unaffected index. continue
+# requires a complete firstmate.fork-rejustify.v1 decision, resolved/staged
+# conflicts, and that exact receipt. It finishes every queued revert before the
+# one manifest update, then validates health against the completed candidate.
+#
+# Neither command pushes, opens a PR, force-updates a ref, or invokes
+# no-mistakes. The task worker validates and delivers the candidate through the
+# isolated fork-target registration.

+# The signal is the PAYLOAD, not the environment, and that choice is

+#   fm-inactive-reconcile.sh acknowledge <fingerprint>
+#
+# This is an adjunct to the existing watcher poll loop and session-start path,
+# not a watcher, daemon, PR poll, or forge client of its own.
+# `scan` evaluates at most once per FM_INACTIVE_RECONCILE_SECS (default 900,
+# valid 60..1800) per home, except that --startup performs the same cheap scan
+# immediately during a locked session start. Each scan has an aggregate
+# FM_INACTIVE_RECONCILE_BUDGET_SECS bound (default 10, valid 1..30) and resumes
+# after its last visited child on the next scan.
+#
+# It considers only a direct ordinary crewmate whose newest meta, status, or
+# turn-ended mtime is older than that interval and whose last status is not
+# captain-held. It then uses fm-crew-state.sh as the sole current-state source.
+# Only a done or failed state is suspicious enough to create a durable terminal
+# outcome record or wake the supervisor.
+# Working, paused, parked, blocked, unknown, persistent secondmates, and
+# captain-held work retain their existing supervision semantics.
+#
+# A terminal-outcomes/<fingerprint>.pending record remains until its upstream
+# receipt is durable.
+# In a secondmate home, that receipt is an idempotent parent-channel status
+# append.
+# In a main home, a presentation-stage record is acknowledged by fm-wake-drain
+# only after its corresponding inactive-outcome wake is handled.
+# A receipt is intentionally independent of .hb-surfaced-* bookkeeping.
+#
+# New fm-terminal-outcome.v1 receipts contain schema, fingerprint, task_id,
+# incarnation, state, outcome_key, origin, phase, pr, created_epoch, and
+# notice_emitted; the fingerprint binds the spawn incarnation, task id, terminal
+# state, PR text, and sanitized last status.
+# Pending atomically becomes reported after parent append or presented after
+# main-home acknowledgement. The atomic epoch/cursor marker's mtime gates scans,
+# and its cursor records the last child visited within the aggregate budget.
+#
+# The scan reads only durable local state and fm-crew-state.sh; it never invokes

+# Condition->action adapter for the generic process-to-event runner: register a
+# deterministic condition and a deterministic action once, let the runner's
+# blocking child poll the condition tokenlessly, fire the action at most once on
+# a stable true, and publish one terminal outcome, re-announced until handled.
+#
+# Usage:
+#   fm-procevent-when.sh arm <name> [options] --condition <argv>... --action <argv>...
+#   fm-procevent-when.sh classify <result-file>
+#   fm-procevent-when.sh terminal <result-file>
+#   fm-procevent-when.sh source-id <name>
+#   fm-procevent-when.sh retire <name>
+#   fm-procevent-when.sh run <source-id>
+#
+# arm        Bind a (condition, action) pair as process-event source
+#            "when-<name>". The spec is written privately under state/when/ and
+#            hash-bound by a trust record the same way fm-check-register.sh
+#            binds a custom check. The action executable is resolved and its
+#            bytes are hash-bound at registration, then checked again immediately
+#            before the fire is claimed. The runner refuses a mutated spec or
+#            action without executing anything. Both argv vectors are executed
+#            directly with no shell, so nothing is re-split or interpreted.
+#            Options, before --condition:
+#              --interval <secs>           poll cadence, decimals allowed (default 60)
+#              --stable <n>                consecutive true polls required to fire (default 2)
+#              --deadline <secs>           give up and wake firstmate if the condition
+#                                          never held this long after arming (default 604800)
+#              --condition-timeout <secs>  per-poll bound on one condition run (default 60)
+#              --action-timeout <secs>     bound on the action run (default 1800)
+#              --error-budget <n>          consecutive condition errors tolerated
+#                                          before waking firstmate (default 3)
+#            The condition argv must exit 0 for true, 1 for a clean false;
+#            any other exit (or a per-poll timeout) is an error, never a true.
+#            POLICY, not enforceable here: both halves must be exact and
+#            deterministic, and the action must be safe and reversible. Anything
+#            needing judgment, and anything destructive, irreversible, or
+#            security-sensitive, keeps the ordinary wake-firstmate-and-decide
+#            flow; this primitive only automates the deterministic subset.
+#            The registered runner starts on the watcher's next cycle via
+#            `fm-procevent.sh reconcile`; arm never blocks on the condition.
+# classify   Print the captured outcome class a handler should act on:
+#            fired, action-failed, condition-error, never-true, ambiguous,
+#            rejected, or unknown.
+# terminal   Exit 0 when the captured result ends this source. Every when
+#            outcome is terminal because the pair fires at most once; the
+#            generic runner then retires the registration itself.
+# source-id  Print the canonical source id for <name>.
+# retire     Stop the watch: retire the registration and remove the spec, trust
+#            record, and fired marker. Idempotent. Captured results and their
+#            handled acknowledgements are never touched. Warns when the action
+#            had already fired without a captured outcome.
+# run        The blocking child the generic runner executes; never run it in a
+#            conversational turn. It polls the condition on the registered
+#            cadence, requires the stable count of consecutive trues, claims a
+#            durable fired marker with an exclusive create BEFORE the action so
+#            a restart or re-poll can never fire the action twice, runs the
+#            action bounded, and emits exactly one outcome document on stdout
+#            for durable capture. Every failure path - mutated spec, condition
+#            error, deadline, action failure, or an earlier fire whose outcome
+#            was never captured - emits a terminal outcome document instead of
+#            retrying silently, so firstmate is always woken with the evidence.
+#
+# Outcome document (the captured result named by the wake):
+#   when: <source-id>
+#   status: fired|action-failed|condition-error|never-true|ambiguous|rejected
+#   detail: <one line>
+#   condition_polls: <n>
+#   action_exit: <code>        (fired and action-failed only)
+#   output:
+#   <bounded tail of the relevant command output>

+# Cursor injects a hook's `additional_context` string straight into model

+# Cursor's payload has no Claude-style `source` field, so the registration
+# supplies it.

+# Every path exits 0 and prints either nothing or one JSON object. Cursor blocks
+# session initialization when a sessionStart hook exits 2 (index.js @ 4823085

 # fm-tmux-lib.sh — shared tmux pane primitives for firstmate.
 #
-# ONE source of truth for: busy detection, composer-empty (pending-input)
-# detection, and a verify-and-retry-Enter submit. Sourced by both the away-mode
-# daemon (bin/fm-supervise-daemon.sh) and bin/fm-send.sh so the composer/submit
-# logic cannot drift between the two.
+# ONE tmux source for delivery-busy detection, composer capture primitives,
+# and verified submit.
+# Both the away-mode daemon and bin/fm-send.sh reach these primitives through
+# backend dispatch, while bin/fm-composer-lib.sh owns the shared verdict.
 #
-# Why this exists (incident afk-invx-i5): the daemon's old composer check only
-# recognized a BARE prompt glyph ("> ") as an empty composer. claude draws its
-# input box with box-drawing borders ("│ > … │"), so every idle claude pane read
-# as "pending input" and the away-mode daemon deferred 100% of escalations for
-# 9.5 hours with no escape. The detector below strips the box borders before
-# deciding, so a bordered-but-empty composer is correctly seen as empty. The same
-# corrected detector backs the submit acknowledgement (a submit "landed" iff the
-# composer is empty afterward), fixing the parallel false "Enter swallowed".
+# Composer shapes and verdicts are owned by bin/fm-composer-lib.sh.
+# This file owns only tmux's styled capture, cursor and Pi identity primitives,
+# delivery busy read, and submit conversions that consume the shared verdict.
+# Styled captures remain internal; fm-peek and every human-facing capture stay
+# plain.
 #
-# Ghost text (incident composer-robust): claude renders a predicted-next-prompt
-# "suggestion" as dim/faint text inside an otherwise-empty composer. A plain
-# capture cannot tell it apart from text a human typed, so the old reader saw an
-# idle pane as holding pending input and the daemon deferred injection / firstmate
-# misjudged the pane. The composer reader now captures the visible pane WITH ANSI
-# styling (tmux capture-pane -e), locates a bordered composer structurally, and
-# extracts the real typed content from every row with the shared, fleet-wide
-# fm_composer_strip_ghost (bin/fm-composer-lib.sh), which drops every
-# de-emphasised run - dim/faint (SGR 2) AND a dark/muted truecolor foreground -
-# so ghost/placeholder text never counts as real input. The styled capture is
-# consumed internally and parsed into a boolean here; it is NEVER surfaced
-# (fm-peek and every human/LLM-facing path stay plain). This is harness-generic:
-# any harness that de-emphasises placeholder/ghost text
-# benefits, and the herdr adapter routes through the same owner (task
-# afk-herdr-false-pending), so the two backends cannot drift.
+# OpenCode's busy-queued Enter conversion accepts only structurally proven
+# pending text after retries, while the separate turn-started conversion accepts
+# an unknown post-Enter composer only after this submit observed an idle baseline
+# become busy.
+# Herdr's OpenCode busy-queue limitation remains documented in
+# docs/herdr-backend.md.
 #
-# Busy-queued Enter (opencode 1.18.4, on the tmux backend only for now): when
-# the agent is mid-turn, opencode accepts Enter as a "send when the turn ends"
-# keystroke but does NOT clear the composer until then, so the composer keeps
-# showing the typed text the whole time. The plain "empty iff composer cleared"
-# acknowledgement above false-positives on a swallowed Enter for every steer
-# sent to a busy opencode pane, and `fm-send` exits non-zero on a normal
-# captain instruction. The submit core now falls back to `fm_pane_is_busy` once
-# the Enter-retry budget is spent: a busy pane means the harness accepted and
-# queued the Enter (report `empty` so the caller does not re-send), while an
-# idle pane keeps the `pending` verdict (a genuine swallow). The herdr backend
-# observes the same opencode behavior but needs a separate fix; it is recorded
-# as a known gap in `docs/herdr-backend.md` rather than patched here, so the
-# tmux adapter does not paper over a herdr-specific shape.

+# Cursor `stop` hook adapter for a firstmate PRIMARY session: the park model.
+#
+# Registered in tracked .cursor/hooks.json. Cursor runs this hook SYNCHRONOUSLY
+# and awaits it at every turn boundary, so one script owns both halves of Cursor
+# primary supervision:
+#
+#   PARK      while supervision is needed, foreground bin/fm-watch-arm.sh and
+#             hold the turn boundary open until the watcher closes with an
+#             actionable wake, then return that wake as the follow-up. No model
+#             tokens are spent while parked. The next turn end parks again, so
+#             the arm/re-arm loop is hook-owned, never model-memory-owned.
+#   BACKSTOP  when the park cannot establish supervision, return the shared
+#             turn-end guard's repair instruction as a bounded follow-up.
+#
+# EXIT 2 IS A SILENT NO-OP ON CURSOR'S stop. Cursor's blocked-response mapper
+# returns an empty object for the stop step (index.js @ 4823085,
+# `e===r.stop ? {} : void 0`), verified live: a stop hook exiting 2 ends the turn
+# normally. This adapter therefore NEVER exits 2 and NEVER writes a diagnostic
+# banner to stderr expecting it to be read. Every path exits 0 and the only
+# channel is at most one {"followup_message": ...} object on stdout.
+# docs/turnend-guard.md:16 accepts one bounded follow-up as an equal alternative
+# to blocking, which is the same primitive OpenCode's session.idle and Pi's
+# agent_settled adapters use.
+#
+# Follow-up sources, in priority order, at most one per invocation:
+#   1. an actionable watcher wake from the park;
+#   2. the bounded repair instruction when supervision could not be established.
+#
+# LOOP BOUNDING IS DOUBLE, because either bound alone is insufficient:
+#   - `loop_limit` in .cursor/hooks.json is Cursor's own ceiling. Once
+#     loop_count reaches it Cursor stops INVOKING this hook at all, so it is the
+#     only bound that still holds if this script is broken or replaced.
+#   - FM_CURSOR_TURNEND_LOOP_CEILING bounds the payload's own loop_count from
+#     inside, deliberately BELOW the registered loop_limit, so firstmate's bound
+#     bites first and can emit one final loud notice instead of going silently
+#     dark at Cursor's ceiling.
+# `loop_count` is Cursor's richer analogue of Claude/Codex `stop_hook_active`:
+# verified live on 2026.08.11-e8db854 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. A genuine wake is productive work, so it does not consume the
+# separate repair budget; only consecutive unproductive repair nags do.
+#
+# SUPERSESSION. A captain message typed while this hook is parked is accepted
+# and runs its turn immediately, and Cursor does NOT terminate the parked hook
+# (verified live). Until that turn ends and the next stop claims the baton, an
+# actionable close can still produce one real, durable-queue-backed follow-up
+# from the sole existing park. Each invocation publishes itself as the current
+# park owner in state/.cursor-park-owner, and once a newer stop has published its
+# claim, an older park still running stands down without emitting. Newest stop
+# wins; the arm's own singleton keeps the overlap from starting a second watcher.

@@ -18,19 +18,29 @@ The receipt makes retirement safely retryable across restarts: fixed-path recove
 A concurrent replacement remains armed, every non-merged or invalid observation remains unchanged, and retirement never performs task or persistent-secondmate cleanup.
 `bin/fm-pr-lib.sh` owns the receipt format and strict identity mechanics, while `bin/fm-watch.sh` owns queue-before-retirement ordering.
 No-verb wakes, such as `working:` notes and bare turn-ended signals, are benign only when `bin/fm-crew-state.sh` reports positive evidence that the crew is still working: an actively running no-mistakes step attributed to that crew's current code, or an exact busy verdict from the semantic busy-state contract.
+A `kind=secondmate` task's status signal is the parent-directed reply stream and is never absorbed as provably working; only its bare turn-ended signal retains the ordinary absorb rule.
 A crew that declares `paused:` for a known external wait is separately absorbed while idle and re-surfaced only on the longer pause cadence, rather than being treated as a possible wedge.
 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 only when the backend confidently reports its agent dead.
 Live or inconclusive liveness remains fail-open at that initial surface, and the secondmate idle-endpoint exemption is unchanged.
 Its initial normal-mode status signal still surfaces through the no-verb path, while away mode self-handles that routine signal and owns the later recheck.
 Fresh stale panes use the same current-state read before trusting the status log, so an active run or a proven busy worker outranks an old captain-relevant status-log line left behind before validation.
 No-change heartbeats are also benign.
+Separately from heartbeat backoff and wedge handling, the watcher poll runs `bin/fm-inactive-reconcile.sh` on its own bounded cadence, while locked session start performs the same bounded local scan immediately.
+In each home the scan considers only that home's long-inactive direct ordinary crewmates, excludes captain-held work, and accepts only `done` or `failed` from `bin/fm-crew-state.sh`.
+A secondmate retains a durable receipt for its idempotent report through the established parent route, and main-home captain presentation retains a separate receipt; neither path performs a forge or PR check.
 Absorbed wakes advance their suppression markers, log to `state/.watch-triage.log`, and keep the watcher blocking without a queue record or LLM turn.
 Each `fm-wake-drain.sh` presentation runs the same liveness guard as the supervision scripts, so a lapsed watcher chain surfaces even on a turn that only handles queued wakes.
 Routine watcher polling, supervision no-ops, elapsed waiting time, and absorbed benign wakes stay silent.
 A declared external wait trades that silence for one bounded recheck per pause window, so a forgotten pause cannot remain invisible indefinitely.
 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 it is explicitly resolved while each presentation reads 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 and last-presented byte offset.
+A queued signal annotation prints every status line still unread at that cursor, while the fleet-wide UNREAD STATUS section prints `note:` lines and reserved-key pending-reply resolutions once even on an empty-queue drain because those verbs never enter the OPEN DECISIONS fold.
+A failed read, output, or concurrent-replacement check prevents the snapshot cursor from advancing across uncertain bytes, and teardown retires a task's manifest row before that task ID can be reused.
 The explicit resolution is written by the actor that answers, not the busy worker: `fm-send`'s `--resolve-key` appends the closing `resolved` line to this home's own copy of the ledger at answer time, which covers crewmates, local secondmates, and remote secondmates identically because a remote mate's escalations reach that local copy through the parent-replies ingest and only the answer message itself crosses the transport.
+This home's answerer close, pending-reply escalation close, and captain-held transfer use the provenance-guarded append owned by `bin/fm-wake-lib.sh`, so they advance the watcher marker only across their own bytes when all earlier bytes were already announced; pending or interleaved foreign bytes fail toward an ordinary wake.
+A turn-ended-only queue row omits its historical status annotation when that status file exactly matches the same seen marker.
+Any direct or remaining historical annotation prints every status line unread at the presentation cursor instead of replaying only the latest line.
 `bin/fm-crew-state.sh <id>` is the cheap current-state read for an actionable heartbeat review: it attributes a no-mistakes run, active or terminal, only when it matches the crew's branch and current code identity, then keeps that run-step authoritative even if the pane has closed.
 The script header owns the exact run-head ancestry rules.
 During no-mistakes' `ci` monitor phase, it also reads the ci step log tail because `axi status` reports both "still waiting on checks" and "checks green, waiting on merge" as `ci,running`.

 Claude's `bin/fm-claude-stop-autoarm.sh` hook fires on every Stop and, when the home is eligible and still needs supervision, claims one home-scoped cycle, foregrounds the arm wrapper, and translates actionable closes into exit-2 rewakes.
 It suppresses failed-looking closes when the same identity-matched watcher is healthy, retries genuine failures within a bound, and coordinates exhausted failure episodes with the Claude turn-end guard as documented in [`turnend-guard.md`](turnend-guard.md).
 [`watcher-continuity.md`](watcher-continuity.md) owns Claude's residual active-turn coverage and watcher-status command-gating boundary.
-The existing turn-end guard remains the final backstop for all five harness-engine protocols, with pi-signed sharing Pi's protocol and the `--claude` mode cooperating with the auto-arm claim.
+Cursor's `bin/fm-turnend-guard-cursor.sh` hook is the same between-turns shape in one synchronous step: it parks the awaited `stop` hook on the arm wrapper and translates an actionable close into one `followup_message`, with a generation baton that makes an older park still running after the next `stop` claim stand down instead of leaking a stale duplicate wake.
+The existing turn-end guard remains the final backstop for every harness-engine protocol, with pi-signed sharing Pi's protocol, the `--claude` mode cooperating with the auto-arm claim, and Cursor's `--cursor` mode rendering a block as one bounded follow-up because its `stop` step cannot be blocked.
 Its `--restart` mode signals only the watcher recorded in the current home's `state/.watch.lock`, so restarting one home cannot kill sibling secondmate watchers.
 A pull-based guard (`bin/fm-guard.sh`) warns through supervision tool output if the primary checkout is tangled, if work, process-event sources, or Relay polling has an unhealthy model-aware supervision verdict, or if queued wakes are waiting to be drained.
 The drain script calls that guard after presenting the queue; records remain durable, and may keep the queued-wakes warning visible, until the exact generation-bound acknowledgement printed by the drain succeeds after handling.
 It leads with a prominent bordered tangle banner, while `bin/fm-guard.sh` owns the watcher-down banner and reminder policy so repeated guarded commands stay noisy without reprinting the full banner in the same episode.
-On every verified primary harness, tracked hook integration gives the primary session a push-based backstop: when work, a process-event source, or Relay polling needs supervision and no identity-matched watcher lock with a fresh beacon is live, direct Stop hooks block and passive turn-end hooks force one bounded follow-up.
+On every verified primary harness, tracked hook integration gives the primary session a push-based backstop: when work, a process-event source, or Relay polling needs supervision and no identity-matched watcher lock with a fresh beacon is live, blocking-capable Stop hooks block and nonblocking turn-end integrations force one bounded follow-up.

+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 `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.
+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.
+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.

 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.
 In supported steady state, a home with no registered source runs nothing, generates no state, and keeps its ordinary cadence.
 
 Whether a captured result ends its source is adapter knowledge, never the runner's.
-After attempting publication the runner calls `bin/fm-procevent-<adapter>.sh terminal <result-file>` and retires the registration on exit 0 alone, 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.
+After capture - and after initial `check` publication for the default ordering - the runner calls `bin/fm-procevent-<adapter>.sh terminal <result-file>` and retires the registration on exit 0 alone, 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.
 A source that has ended therefore captures at most one terminal result, is never restarted, and leaves no recurring poll work, while explicit `retire` stays the supported and idempotent path afterwards.
 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.
 
 Applying a captured result is adapter knowledge too, and some 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>` only when this capture's own wake was successfully appended to the durable queue, then lets the 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.
-Failed publication skips the call, and exit 0 means the adapter fully applied and acknowledged the result; failed publication, 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.
+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, a byte-identical replayed capture adds no bytes and stays quiet, and only a capture the adapter could not fully apply is published as a `check` wake, whose adapter handling remains idempotent.

 `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.

+# Fork main integration
+
+A Firstmate home can run from a personal fork's `main` as a permanent integration branch while continuing to receive the official repository's changes.
+This is a maintained divergence workflow, not a temporary staging branch.
+The fork is healthy only when its named divergence set stays small, turns over, and trends down.
+
+## Remote topology
+
+The guarded topology uses two remotes and requires each remote's fetch and push URLs to name the same place.
+
+- `origin` is the personal fork and local `main` tracks `origin/main`.
+- `upstream` is the official repository and is pull-only by policy.
+- Linked task worktrees and leased local secondmate homes share the repository's common Git configuration and refs.
+- Newly provisioned standalone local and remote secondmate homes inherit the validated URLs through their provisioning owners.
+- Remote code roots consume fork main and never integrate official upstream independently.
+
+A fresh home initializes no-mistakes while the official repository is still `origin`, naming the personal fork with `--fork-url`.
+It then uses `gh-axi repo fork --remote` so GitHub CLI makes the fork `origin` and renames the official remote to `upstream`.
+Run the guarded `plan` and confirmed `apply` below afterwards; the already-renamed case validates the exact URLs, proves the no-mistakes registration, and establishes the branch and rerere policy without renaming again.
+This preserves the ordinary no-mistakes registration as the upstream-submission lane while giving the operating checkout the correct fork topology.
+
+Changing `origin` on a running captain home is never a startup or self-update side effect.
+Inspect the plan first:
+
+```sh
+bin/fm-fork-remotes.sh plan <fork-url> <upstream-url>
+```
+
+The plan prints the exact apply and reverse commands.
+Run the apply command only after the captain confirms that concrete live-home migration.
+The apply path requires a literal `--confirm`, validates both URLs before changing names, proves the ordinary no-mistakes registration still names official upstream plus personal fork before and after migration, enables repository-local rerere, and leaves rerere autoupdate explicitly off.
+A failed post-migration registration proof restores the original Git topology rather than reconfiguring or retrying no-mistakes.
+The `--no-registration` form is reserved for provisioned remote code roots that never validate changes themselves; never use it to bypass a registration failure in an operating primary.
+The reverse path restores official upstream as `origin`, retains the personal fork as `fork`, and never rewrites a commit.
+
+## Two validation targets
+
+Ordinary topic validation and fork integration validation must not share one mutable no-mistakes registration.
+The ordinary registration keeps official upstream as its remote and the personal fork as its push target.
+A private integration clone uses the fork as its no-mistakes remote so its pull requests target fork main.
+
+Inspect or provision that clone with:
+
+```sh
+bin/fm-fork-integration.sh plan <fork-url> <upstream-url>
+bin/fm-fork-integration.sh ensure <fork-url> <upstream-url> --confirm
+bin/fm-fork-integration.sh check <fork-url> <upstream-url>
+```
+
+The private clone defaults to `data/fork-integration` and therefore stays outside tracked source and project clones.
+Provisioning snapshots the ordinary registration's upstream and fork facts before any init and proves them byte-identical afterwards.
+It refuses an existing mismatch rather than refreshing either registration.
+A no-mistakes error stops the operation and never restarts, updates, or reconfigures the shared service.
+
+## One canonical topic per divergence
+
+Each carried divergence has one canonical branch named `fm/divergence/<id>`.
+Start a Firstmate divergence brief from official upstream rather than detached fork main:
+
+```sh
+bin/fm-brief.sh <task-id> firstmate --mode no-mistakes --start-ref upstream/main
+```
+
+The exact `upstream/main` start ref also makes the generator place the fork worker contract in the brief that `fm-spawn.sh` delivers as its typed launch input.
+That delivered contract loads `fork-main-integration`, forbids rewriting a published topic or pull-request branch, forbids routine upstream or fork-main merges into the topic, and keeps topic validation on the ordinary official-upstream registration.
+The focused regression for this delivered contract is [`tests/fm-fork-main.test.sh`](../tests/fm-fork-main.test.sh).
+
+A canonical new topic has one aggregate non-merge patch commit before its first fork integration.
+This constraint matters because `git cherry` compares patches one commit at a time.
+It recognizes the same one-commit patch after upstream squash or rebase changes its commit ID, but it cannot prove that several topic commits equal one aggregate upstream squash.
+
+Never rewrite a published pull-request branch to manufacture that shape.
+A legacy multi-commit submission gets a fresh one-commit canonical divergence topic, while its original pull-request head remains a linked delivery artifact.
+Use `git range-diff` to review the relationship between the submitted series and canonical patch.
+
+A topic does not habitually merge fork main or official upstream.
+Git's own workflow guidance reserves a downstream merge for a concrete reason, such as an upstream API change reaching the topic or a topic that no longer merges cleanly.
+Fork main is the integration branch and receives upstream regularly.
+The captain's 2026-08-14 ruling requires DAILY official-upstream synchronization.
+
+## Integrate and discard a topic
+
+Prepare a divergence integration only in an isolated worktree of the private integration clone.
+The helper requires fetched fork main as the exact starting point, one `git cherry` non-equivalent commit on the canonical topic, complete manifest path coverage, and a concrete retirement condition.
+
+```sh
+bin/fm-fork-topic.sh integrate \
+  --id <id> \
+  --summary '<one sentence>' \
+  --class <pending|rejected-but-retained|private> \
+  --topic fm/divergence/<id> \
+  --retire-when '<falsifiable condition>' \
+  --path <path-or-directory-prefix> \
+  [--pr-url <full-url> --pr-disposition <open|rejected>] \
+  --repo <isolated-worktree>
+```
+
+The helper merges with `--no-ff --no-commit`, adds the manifest entry to that merge, commits the two-parent result, and validates health against candidate `HEAD`.
+It never pushes or opens a pull request.
+A product conflict exits 3 with Git's merge state intact and a private receipt that binds the branch, original head, topic merge head, manifest, conflict paths, and unaffected index.
+Settle whether the divergence remains worth carrying, resolve and stage the product files, and write a complete `firstmate.fork-rejustify.v1` decision with action `retain` outside the candidate.
+Continue with:
+
+```sh
+bin/fm-fork-topic.sh continue --decisions <file> --repo <isolated-worktree>
+```
+
+The continuation refuses a changed branch, merge head, manifest, unaffected index, incomplete decision, unstaged resolution, or untracked file.
+It writes the manifest entry into the completed merge commit and validates that candidate.
+The worker runs no-mistakes through the isolated fork registration, runs health against the actual post-pipeline head, waits for fork CI, and the captain merges the fork pull request with the regular merge method so the topic merge remains reachable.
+
+Discarding selects only the named topic's integration merges on fork main's direct first-parent history or one regular pull-request candidate range beneath it, then reverts them newest to oldest with mainline parent one:
+
+```sh
+bin/fm-fork-topic.sh discard --id <id> --repo <isolated-worktree>
+```
+
+A manifest-only overlap from a later topic is preserved mechanically while the named entry is removed.
+Any product-file conflict stops for re-justification with a receipt bound to the branch, original head, active revert head, queued integration merges, manifest backup, conflict paths, and unaffected index.
+After settling the remove decision and staging the product resolution, use the same `continue` command above with action `remove`.
+The helper finishes the complete `git revert --no-commit` sequence, collects any continuation commits back into the unpublished candidate, removes the manifest unit, and records product plus governance changes in one final commit.
+The resulting branch still goes through no-mistakes, post-pipeline health, fork CI, pull request, and captain approval.
+
+Git documents an important merge-revert consequence.
+A reverted merge tells later merges that its ancestors are unwanted.
+Re-enabling a discarded topic therefore requires reverting the revert or introducing a genuinely new topic version, not blindly merging the old branch again.
+
+## Manifest
+
+The tracked [`fork-divergences.json`](../fork-divergences.json) file uses schema `firstmate.fork-divergences.v1`.
+Git owns patch facts, and the manifest owns only intent Git cannot know.
+
+Every divergence records:
+
+- a stable ID and one-sentence summary;
+- exactly one class: `pending`, `rejected-but-retained`, `private`, or `superseded`;
+- its canonical topic branch;
+- introduction date;
+- upstream pull request and recorded disposition when it is not private;
+- the concrete falsifiable condition that retires it;
+- every exact path or directory prefix its patch touches.
+
+`pending` means upstream review remains open and therefore pairs only with pull-request disposition `open`.
+`rejected-but-retained` means upstream declined it but current evidence still justifies carrying it, so it pairs only with pull-request disposition `rejected`.
+`private` means it is intentionally not proposed upstream, carries no pull-request record, and should remain small.
+`superseded` is immediate removal debt and must be empty after an upstream integration.
+
+An upstream-sync record keeps the pre-merge fork SHA, previous and incoming upstream SHA, date, touched divergence IDs, and an optional validation pull-request URL.
+Counts are derived from Git rather than copied into the manifest.
+The history stays bounded to the latest 20 integrations.
+
+A `retired_upstream` record is the one exception to deriving facts from Git, because it preserves a fact Git can no longer recompute.
+It keeps the retired unit's ID, canonical topic, summary, retirement date, the fork commit that carried the patch, the upstream commit that carries the same patch, and their shared patch ID.
+Each record is written into the same upstream merge that removes the active divergence entry, so the divergence count can never fall without the evidence explaining it.
+Records are not bounded, because a fork patch stays in history forever and its proof must stay auditable for exactly as long.
+A retired ID is never reused for a new divergence.
+
+Update the manifest in the same fork integration or upstream merge that changes the divergence set.
+A follow-up is not acceptable because a stale manifest looks authoritative.
+
+## Health report
+
+Run the local network-free report with:
+
+```sh
+bin/fm-fork-status.sh
+```
+
+Add `--refresh` to fetch both remotes and compare recorded GitHub pull-request dispositions through `gh-axi`.
+Refresh fails closed when live disposition evidence is incomplete or its response shape is unsupported.
+Add `--json` for schema `firstmate.fork-health.v1`.
+
+The report uses `git cherry upstream/main origin/main` for one fact only: which commits have no equivalent upstream patch.
+The manifest supplies the meaning of what the fork intends to carry, so active patch counts come from each manifest unit's canonical topic rather than every raw `+` line.
+A non-upstream commit outside those canonical patches is a visible signal, not automatically a carried divergence or a failed report.
+A validation fix descending from a recognized topic or upstream integration is attributed as an `integration-path` artifact.
+A manifest-only review-disposition commit is attributed as a `manifest-governance` artifact.
+After no-mistakes, validate the actual post-pipeline candidate because helper-prepared health cannot classify commits that validation added later:
+
+```sh
+bin/fm-fork-status.sh --repo <isolated-worktree> --fork-ref HEAD --facts-only
+```
+
+This candidate-only mode still prints the trend but limits its exit-status verdict to Git and manifest consistency plus superseded debt; do not use it to characterize the running fork as healthy.
+
+The report names active units and canonical patches, all factual non-upstream commits, integration artifacts, informational signals, trend since the previous upstream merge, counts by class, the oldest pending unit, the latest merge's touched units, retirement conditions, every accepted-upstream retirement with its proof, superseded debt, and structural health errors.
+
+A merge revert leaves both the original patch and its inverse in history, so both remain raw `git cherry +` facts after their net effect is gone.
+The status owner excludes a pair from active health only when Git proves the exact reachable `git revert -m 1 <topic-merge>` relationship.
+It reports the excluded count as retired history rather than hiding it.
+
+An upstream-accepted patch is the second exclusion, and it needs stored evidence because Git stops being able to recompute the fact.
+Git documents `git cherry`'s equivalence search space as `<head>..<upstream>`, so once the integration merge makes upstream an ancestor of fork main, that range is empty and the fork's own copy of the accepted patch is a raw `+` fact forever.
+The status owner therefore re-derives each `retired_upstream` record from reachable objects instead of trusting it: the recorded fork commit must still be a carried patch on fork main, the recorded upstream commit must still be reachable from `upstream/<default>`, and both must still hash to the one recorded patch ID.
+Only that independent proof excludes the patch, and the report names every retirement with the fork commit, upstream commit, and patch ID it rests on.
+A record that is stale, contradictory, unproved, or missing leaves its patch counted and reported, never silently excluded.
+PR state, commit messages, branch names, ancestry, and stated intent never retire a patch.
+
+The report is unhealthy when one canonical patch has multiple manifest owners, one canonical topic has several non-equivalent commits, a topic or integration merge is missing, declared paths omit a changed file, a pull-request disposition is stale, a recorded retirement no longer re-proves, any superseded unit remains, or retained canonical patches trend up.
+A manifest unit whose topic has become equivalent upstream is signaled for retirement review rather than misreported as a raw-patch ownership failure.
+An unrepresented non-upstream commit is likewise a signal until an operator classifies its meaning.
+The signal remains named and counted, so this distinction does not hide the Git fact.
+
+`git range-diff` remains a human review tool because Git documents its output as version-unstable and not machine-readable.
+When the latest upstream integration touched a divergence, the health report prints the exact `git range-diff --remerge-diff` command for review.
+Export one topic's portable patch with `git format-patch upstream/main..fm/divergence/<id>`.
+
+## Upstream integration
+
+`/updatefirstmate` keeps live homes fast-forward-only.
+Before the first origin-based fast-forward, each code root with an `upstream` remote must pass the fork topology check exactly once; a failure names the missing fact and the guarded correction before any code commit moves.
+It advances each code root from validated fork `origin/main`, then advances subordinate homes to that root's exact commit without trusting their own origin, and finally reports whether official upstream still needs a separate integration.
+It never merges in the operating checkout.
+
+Locked startup performs the same non-merging need probe as part of its deferred network work and emits `UPSTREAM_SYNC:` only when a validated merge is needed or the check failed.
+It probes at most once per successful 24-hour interval; a failed probe writes no success marker and therefore remains eligible on the next startup.
+That probe runs only once `bin/fm-fork-remotes.sh check` passes.
+A home that has an `upstream` remote but has not finished the explicit migration is reported as `UPSTREAM_SYNC: fork topology is not validated: <first missing requirement>` on every startup, with no probe and no daily marker written, so a half-configured home stays loud until it is corrected or reversed.
+A home with no `upstream` remote at all is classic single-origin and stays silent.
+The main primary owns that work.
+Secondmates and remote code roots do not create competing merges.
+
+Prepare a candidate in an isolated worktree of the private integration clone:
+
+```sh
+bin/fm-fork-merge.sh prepare --repo <isolated-worktree>
+```
+
+A clean result creates a two-parent upstream merge, moves each unit whose canonical patch Git proves equivalent to a reachable upstream commit and whose equivalent patch reverses cleanly from the incoming upstream tip into `retired_upstream` with that proof, records the sync input, runs `git range-diff --remerge-diff`, and validates health against candidate `HEAD`.
+A unit that is equivalent upstream but no longer has exactly one aggregate patch commit stops the merge instead of retiring, because that single commit is the whole proof boundary.
+It does not push or invoke no-mistakes.
+The worker validates through the fork registration, runs health against the actual post-pipeline head, and opens a fork-main pull request.
+
+A conflict exits with code 3, leaves the merge and rerere result unstaged, identifies affected manifest units, and writes a worktree-private re-justification receipt.
+Decide whether every affected divergence remains worth carrying before resolving it.
+Continue only with a complete decision file:
+
+```json
+{
+  "schema": "firstmate.fork-rejustify.v1",
+  "decisions": [
+    {
+      "id": "example",
+      "action": "retain",
+      "reason": "The accepted behavior still requires this fork-specific guard."
+    }
+  ]
+}
+```
+
+Keep the decision file outside the candidate's working tree, then run:
+
+```sh
+bin/fm-fork-merge.sh continue --repo <isolated-worktree> --decisions <file>
+```
+
+The decision action is only `retain`, and a retained unit remains an active manifest owner even when its historical patch is equivalent upstream.
+An upstream conflict with no manifest path owner uses the explicit `__unowned__` ID and still requires a reason.
+The helper refuses a changed branch, changed merge head, missing decision, short reason, or unresolved index.
+
+If the conflict evidence instead justifies complete removal, settle the stopped operation without publishing a merge:
+
+```sh
+bin/fm-fork-merge.sh abort --repo <isolated-worktree>
+```
+
+Then use `bin/fm-fork-topic.sh discard --id <id>` from that restored candidate, advance fork main through the ordinary validated pull-request path, and retry upstream preparation.
+The receipt-bound abort refuses any branch, head, or merge that differs from the stopped operation and removes its receipt only after Git restores the recorded clean fork head.
+
+Rerere records the accepted resolution and can replay it on the next equivalent conflict.
+Because `rerere.autoupdate=false`, replay changes the working tree but keeps unmerged index stages, preserving the review and re-justification barrier.
+Rerere cannot recover conflict resolutions made before it was enabled.
+
+After the fork pull request lands, `/updatefirstmate` performs only safe fast-forwards from fork main into each validated code root and propagates that exact commit into its local or remote subordinate homes.
+
+## Upstream review after local adoption
+
+Upstream review is evidence, not the local shipping gate.
+A change enters use only after its topic validation, fork merge candidate validation, green fork CI, captain-approved fork pull request, and safe fleet update.
+
+If upstream rejects a useful running change, reclassify it from `pending` to `rejected-but-retained` in the next validated fork integration through the supported interface:
+
+```sh
+bin/fm-fork-topic.sh disposition \
+  --id <id> \
+  --class rejected-but-retained \
+  --pr-disposition rejected \
+  --repo <isolated-worktree>
+```
+
+The helper changes the class and recorded pull-request disposition together, commits the governance transition, and validates candidate health.
+Keep or sharpen its falsifiable retirement condition.
+Do not roll it back merely because upstream declined it, and do not leave it mislabeled.
+
+If upstream review reveals a correctness or security problem that applies locally, prior local validation does not overrule that evidence.
+Fix the topic or use the independent discard path immediately.
+
+When upstream accepts an equivalent patch, `git cherry` removes it from the active patch set even when squash or rebase changed the SHA.
+That equivalence is visible only until the integration merge lands, so the next upstream integration captures it as a `retired_upstream` proof in the same commit that removes the manifest unit, and preserves upstream's implementation.
+A materially edited upstream version can still conflict, which is exactly when range-diff and the retirement condition must decide which behavior remains.

+Compaction is covered where a tracked adapter delivers that source because a compacted session has lost exactly the digest it needs, and resume is excluded from the run because it restores that digest instead of losing it.
 
 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` already treats a lock this session's own harness holds as its 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 the nudge cannot also fire: `resume`, `reload`, and `fork` are the only sources routed to it, and on those its own ancestry check stays silent whenever this process already holds the lock.

+   After handling all emitted wakes and reconciling open decisions, run the exact `--ack-through` command printed as `WAKE_ACK_REQUIRED`; until then the work remains durable for idempotent re-handling after interruption.
+2. Routine watcher arm and re-arm are owned by the `stop` hook (`bin/fm-turnend-guard-cursor.sh`), never by you.
+   Cursor runs that hook synchronously and awaits it, so every turn end while supervision is needed parks the turn boundary open on one home-scoped watcher cycle, with no model command and no model tokens spent while parked.
+3. An actionable close wakes you as a follow-up turn carrying the `watcher` operational kind.
+   On that wake, run `bin/fm-wake-drain.sh` first and handle it.
+   Do not run `bin/fm-watch-arm.sh` after an ordinary wake; the next turn end parks again automatically when supervision is still needed.
+   Do not invent a wake from an attach-status line alone; drain and act only on real wake records, the drain's `OPEN DECISIONS` entries, or a real watcher reason line.
+4. The captain keeps control while the hook is parked.
+   A message typed into a parked Cursor pane is accepted and runs its turn immediately, but the older park remains the recorded owner until that turn ends and the next `stop` hook claims the baton.
+   An actionable watcher close in that window can still be delivered by the older park as one follow-up.
+   This is bounded and safe: only one park exists in that window, so the event is a real wake rather than a stale duplicate of another park's wake, the durable wake queue makes handling idempotent, and the next `stop` claim makes an older park that is still running stand down without emitting.
+   The private supersession records are `state/.cursor-park-owner` and its short publication and commit lock `state/.cursor-park-owner.lock`.
+5. On a `turn-end-guard` follow-up, the park could not establish a live cycle.
+   Inspect the watcher startup path rather than turning the notice into a repeating manual-arm loop; the nag is bounded by `FM_CURSOR_TURNEND_BLOCK_BUDGET` (default 3) and then stops on its own.
+6. Treat `watcher: started ...` and `watcher: attached ...` inside park output as proof that one live cycle exists.
+   On attach, the arm follows verified identity-matched successors instead of exiting when the first cycle ends.
+7. The durable wake queue preserves actionable events between a follow-up and the next park.
+   [`watcher-continuity.md`](../watcher-continuity.md) owns the exact session-lock recovery boundary.
+8. Waiting on the hook-owned park is silent: do not send idle progress while the watcher is parked.
+
+The watcher itself remains `bin/fm-watch.sh`, and `bin/fm-watch-arm.sh` remains the verified arm wrapper that the `stop` hook runs as its own tracked child.
+Re-arm attaches to an existing healthy cycle when one is already present and follows its verified successor chain.
+See [`watcher-continuity.md`](../watcher-continuity.md) for the arm-layer successor and clean-close failure contract.
+
+Exit status 2 is a silent no-op on Cursor's `stop` step, so this adapter never blocks a turn end and instead forces one bounded follow-up, which [`turnend-guard.md`](../turnend-guard.md) accepts as an equal alternative.
+That document owns the double loop bound, the supersession contract, and the compatibility limits, including that a Cursor primary must be launched with `--trust` for its project hooks to load at all.
+Cursor's `beforeSubmitPrompt` step fires once for a real captain message and not for hook-driven follow-ups, so it could invalidate the baton at the start of this window, but that registration is deliberately deferred alongside the `preCompact` surface.

 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.
 `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.
 Under the Claude Stop auto-arm model a beacon fresh within grace is healthy even with no live watcher process, and only a beacon stale beyond grace (or absent) alarms.
+Under the Pi extension model 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 session provably owns continuity, because `.pi/extensions/fm-primary-pi-watch.ts` tears the watcher down on every actionable wake and spawns the replacement itself.
+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.
+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_pi_extension_owns_supervision` in `bin/fm-wake-lib.sh`: both Pi primary extensions 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.
+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 session is loud immediately, and a cycle the extension never restores is loud once the beacon passes grace.
 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.

 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.
 Grok's project hook requires the checkout to be trusted with `/hooks-trust` or launch-time `--trust`; genuine pre-native builds can run the same tracked hook from an isolated global hook directory.
 
+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.
+`bin/fm-turnend-guard-cursor.sh` therefore never exits 2 and never writes a banner expecting it to be read; 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.
+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.
+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.
+
+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 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.
+Without those records an older park still running after the next `stop` could leak one process and one stale duplicate wake.
+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.
+That hook is deliberately left to a follow-up alongside the deferred `preCompact` surface and is not registered in this change.

-Lavish is the first adapter; adding another requires only a new `bin/fm-procevent-<adapter>.sh`, whose `terminal` command is optional and defaults to keeping the source armed.
+The runner is domain-neutral and creates no endpoint, task metadata, or backlog item, so the supported primary harnesses and runtime backends are unaffected except through the existing `check` and status-signal wake paths they already consume.
+Adapters extend the runner through `bin/fm-procevent-<adapter>.sh`; the `when` adapter also uses the runner library's locked registration publisher so its private trust state and source registration are serialized under one source boundary.
+An adapter's `terminal` command is optional and defaults to keeping the source armed.
 Its `autohandle` command is optional in the same way and defaults to leaving the captured result unacknowledged, so it keeps being announced to a handler exactly as before.
+The optional `self-announcing` declaration changes ordering only for an adapter with its own durable downstream announcement; the operating contract in `docs/configuration.md` owns that boundary.
 
 Proactive delivery is inside that same boundary.
 The watcher reports a queued process-event result through the one shared actionable-exit path (`wake` in `bin/fm-push-transition-lib.sh`) that every existing signal, stale, and check wake already uses, so it reads no pane, queries no backend, and names no harness.

+## Composer classification matrix
+
+The shared composer classifier (`bin/fm-composer-lib.sh`, `fm_composer_classify_screen`) owns every composer shape fleet-wide; each backend contributes only a capture and a capability descriptor.
+The live half of that guarantee was verified on 2026-08-10 from an already-trusted checkout at the branch's final validated head, against every installed harness then covered by the empty-composer matrix on tmux 3.6a, macOS arm64, on an isolated private socket, with no prompt submitted to any harness.
+An earlier untrusted-worktree run left Claude, Grok, and Muse unverified because the guard treats first-launch trust dialogs as an unreadable-composer state and never confirms them; this trusted-checkout rerun supersedes those missing results.

+## Cursor Agent CLI
+
+Cursor runs crewmate, scout, secondmate, and primary work; [`supervision.md`](supervision.md#cursor-primary-park-2026-08-13) owns the primary evidence.
+The evidence below was produced on 2026-08-11 against the installed signed CLI on macOS 26.5.2 arm64 with tmux 3.6a, running as `kunchenguid`, and extended on 2026-08-13 with the tmux composer verdict below.
+
+- Binary: `~/.local/bin/cursor-agent`, canonicalizing into `~/.local/share/cursor-agent/versions/2026.08.11-e8db854/cursor-agent`.
+- Version: `cursor-agent --version` reported `2026.08.11-e8db854`, and `cursor-agent status` reported a logged-in account.
+- Both installed names, `cursor-agent` and the legacy alias `agent`, resolve into that same versioned install tree.
+
+Resolution prints the STABLE launcher rather than the canonical target, because the canonical path carries a version the CLI replaces on its own auto-update.
+
+### Process identity
+
+`#{pane_current_command}` and `ps -o comm=` disagree for cursor, which is why identity reads both:
+
+| Source | Observed value |
+| --- | --- |
+| `#{pane_current_command}` | `node` |
+| `ps -o comm=` | `/Users/<user>/.local/bin/cursor-agent` |
+| child argv | `.../bin/cursor-agent --use-system-ca .../versions/2026.08.11-e8db854/index.js --trust --yolo` |
+
+`node` matches no harness name pattern, so a cursor pane is identified from Cursor's own name or install tree in the path or argv[0].
+An unrelated `node` or `agent` matches neither and classifies `other`, which the liveness callers fold into `ambiguous` rather than `dead`.
+A live cursor pane returned `alive`; a plain shell pane in the same run returned `dead`.
+
+### Environment markers and detection ordering
+
+Read from the live agent process and from a tool subprocess it spawned:
+
+| Marker | Where observed |
+| --- | --- |
+| `CURSOR_INVOKED_AS=cursor-agent` | the agent process itself, and its children |
+| `CURSOR_AGENT=1` | child/tool processes only |
+| `CURSOR_CONVERSATION_ID=<uuid>` | child/tool processes |
+| `AGENT_TRANSCRIPTS=<projects-root>/<slug>/agent-transcripts` | child/tool processes |
+
+Cursor does not clear an inherited `CLAUDECODE`, so ordering decides the verdict.
+With both markers set, `bin/fm-harness.sh` reports `cursor`; with `CLAUDECODE` alone it still reports `claude`.
+
+### Composer
+
+Cursor's composer is a BARE row whose prompt glyph is `→` (U+2192); there is no border.
+Its idle placeholder is `Plan, search, build anything` in a fresh session and `Add a follow-up` after a completed turn.
+
+The styled capture of an idle composer row was:
+
+```
+ESC[48;2;21;21;21m ESC[2m→ ESC[0;7mESC[48;2;21;21;21mPESC[0;2mESC[48;2;21;21;21mlan, search, build anythingESC[0m
+```
+
+The glyph and the placeholder tail are dim (SGR 2), but the cell under the terminal cursor is reverse video (SGR 0;7).
+Reverse video is neither dim nor a dark foreground, so ghost stripping leaves a lone `P` and an idle composer read `pending` before the fix.
+After teaching the shared classifier the glyph, both placeholders, and the plain-row remnant rule, the same captures read `empty` on the styled cursorless backends, while real typed text - including text typed to exactly match the placeholder - still read `pending`.
+An unstyled capture has no ghost-strip proof and correctly stays `unknown`.
+
+#### tmux composer verdict, corrected 2026-08-13
+
+The 2026-08-11 record that a Cursor pane's tmux composer verdict is `unknown` in every state described the cursor-ANCHORED read, which remains true: `#{cursor_y}` was 25 with `#{cursor_flag}` 0 on an idle pane, pointing below the footer, so tmux's cursor row is not a composer locator for Cursor.
+Read cursorlessly, the same live capture classifies correctly, so the composite verdict is no longer `unknown`:
+
+```text
+cursor_y=25  cursor_flag=0
+with-cursor : unknown      cursorless : empty     (idle composer)
+with-cursor : unknown      cursorless : pending   (real typed text, not submitted)
+with-cursor : unknown      cursorless : unknown   (agent exited to a shell)
+```
+
+`bin/fm-tmux-lib.sh` therefore reclassifies cursorlessly only when the pane's foreground process group is provably Cursor, so every other harness keeps the strict blank-cursor-row posture.
+That supplies the genuine composer-empty proof required for away-mode escalation delivery.
+A live injection through `bin/fm-supervise-daemon.sh`'s own `inject_msg` into a real Cursor pane returned 0 and the pane processed the typed `FIRSTMATE_OP: v1 away-supervisor:` escalation.
+
+`tests/fm-tmux-agent-liveness.test.sh` pins this with real processes and no Cursor installed: it asserts the cursor-anchored source is blind, that the composite still reads `empty` idle and `pending` with typed text, that an identical screen stays `unknown` when the pane is not Cursor, and that a stale Cursor screen over a dead shell never reads `empty`.
+
+### Busy state
+
+Cursor writes a per-conversation transcript at `<projects-root>/<workspace-slug>/agent-transcripts/<conversation-id>/<conversation-id>.jsonl`.
+Each turn is bracketed by a `role:user` open and a typed `{"type":"turn_ended","status":...}` close.
+Observed closes: `success` for a completed turn, and `aborted` with `"error":"User aborted/interrupted manually."` after a single Escape.
+
+The trailing close landed 0 seconds after the pane's busy footer cleared on a normal turn.
+The transcript does NOT accumulate one close per turn, so a count of closes is not a progress signal; only the trailing record is.
+After an interrupt the aborted close was observed within seconds in some runs and not within twenty seconds in others, so `bin/fm-control-lib.sh` deliberately claims no cancellation acknowledgement for cursor.
+
+Binding never reconstructs cursor's workspace-slug directory name, which collapses path separators.
+Cursor records the exact absolute workspace path in each project directory's `.workspace-trusted`, and the binding matches on that value.
+
+### Rendered busy token, delivery only
+
+Mid-turn the pane showed a braille spinner plus a verb, and `ctrl+c to stop` on the composer row; both the verb line and that token were absent the instant the turn ended.
+The same version rendered `Working` in one turn and `Running` in the next, so the TOKEN is matched and the verb is not.
+This row is a delivery guard for submit acknowledgement only; recorded worker state comes from the transcript fold.
+
+### Launch, lifecycle, and skills
+
+| Fact | Observed |
+| --- | --- |
+| Workspace trust | `--trust` suppressed the prompt; `--yolo` alone did NOT, and the prompt blocks a fresh worktree |
+| Autonomy | `--yolo` (alias of `--force`); the footer renders `Run Everything` |
+| Worktree | `-w/--worktree` allocates a SECOND worktree under `~/.cursor/worktrees` and is never passed |
+| Effort | no effort flag exists; requested effort stays in task metadata |
+| Interrupt | single Escape; the pane showed `Cancelled` and the composer returned to its placeholder, so no clear key is needed |
+| Exit | `/exit` |
+| Skill invocation | `/<skill>`; cursor discovers firstmate's user-level skills, and `/no-mistakes` autocompleted with firstmate's own description and invoked the skill |
+| Slash popup | real: the first Enter closes the popup and a SECOND Enter submits, the same hazard as grok, covered by the submit core's retried Enter |
+
+### End-to-end
+
+A throwaway scout was spawned through `bin/fm-spawn.sh --scout --backend tmux` on a real cursor worker and driven to completion:
+
+1. the launch delivered its brief positionally and the agent executed it;
+2. `state/<id>.cursor-session` was written with the task worktree;
+3. the transcript fold read `busy` mid-turn and `idle` after it;
+4. `bin/fm-send.sh` delivered a steer and exited 0;
+5. `bin/fm-control.sh <id> interrupt` cancelled a running turn;
+6. `bin/fm-control.sh <id> exit` stopped the agent;
+7. `bin/fm-teardown.sh` refused until the scout's report and decision gate were satisfied, then removed the session record.
+
+### Herdr backend
+
+The tmux run above is the reference; this section is the separate Herdr proof, produced on 2026-08-12 against Herdr 0.8.0 (client and server, protocol 19) and the same signed `cursor-agent` 2026.08.11-e8db854 on macOS 26.5.2 arm64.
+Every step ran inside an isolated `fm-lab-` session provisioned by `bin/fm-herdr-lab.sh`, launched from a neutral parent outside any Herdr pane, with the live default session's pane count checked before, during, and after; it stayed at 7 throughout.
+
+**Herdr's native agent state is unusable for Cursor.**
+A 60-sample probe of `agent get` across a full turn reported `agent_status=blocked` in every state - idle, mid-turn, and after.
+The submit path's idle baseline is therefore structurally unreachable for Cursor, and every send falls into the composer branch.
+
+| Pane state | Composer verdict | Rendered footer |
+| --- | --- | --- |
+| Idle | `empty` | no busy token |
+| Text typed, not submitted | `pending` | no busy token |
+| Mid-turn | `pending` (placeholder plus `ctrl+c to stop` on one row) | `ctrl+c to stop` |
+
+Herdr draws the composer's rules with the half-block glyphs U+2584 and U+2580 rather than the box-drawing family.
+Before those were taught to the shared edge detector, a bare composer's wrap region ran through its own closing rule and swallowed the model and path footer, so an idle pane read `pending`.
+Measured as an A/B on the same live pane, the pre-fix classifier returned `pending` and the current one returned `empty`.
+
+The idle fix alone did not confirm delivery, because the composer branch reads the mid-turn row instead.
+With the rendered-footer transition in place, `bin/fm-send.sh` exited 0 and the steer executed in the pane; the same send previously exited 1 with `delivery unconfirmed; verdict=pending` on a message that had actually landed.
+
+The rest of the lifecycle was driven end to end on that worker:
+
+1. `bin/fm-spawn.sh --scout --backend herdr` placed the worker and it executed its brief;
+2. the transcript fold read `busy` mid-turn and `idle` after, unchanged from tmux, so the recorded worker state is backend-agnostic;
+3. `bin/fm-control.sh <id> interrupt` reported `cancel=unconfirmed` by design and the pane showed `Cancelled`, with the footer and the fold both returning to idle;
+4. `bin/fm-control.sh <id> exit` stopped the agent through the slash popup and the pane returned to its shell;
+5. `bin/fm-teardown.sh` refused until the scout's report and decision gate were satisfied, then removed the session record and returned the worktree.
+
+Other harnesses on Herdr are unaffected by the edge-detector change.
+All seven live panes of the running default session - one Pi, four Claude, two plain shells - classified identically under the pre-fix and current classifiers.
+
+**Delivery confirmation is verified on tmux and Herdr only.**
+Zellij, cmux, and Orca share a submit core that never consults the busy footer, so a Cursor steer there lands but `fm-send` reports delivery unconfirmed and exits non-zero.
+Teaching that shared core the same transition is deliberately separate work, because it changes the submit path for every harness on those three backends and needs its own live validation on each.
+
+The portable regression is `tests/fm-cursor-harness.test.sh`, the composer captures are pinned in `tests/fm-composer-lib.test.sh`, and the Herdr submit and footer behavior is pinned in `tests/fm-backend-herdr.test.sh`.

+### Cursor primary park, 2026-08-13
+
+Cursor was validated as a primary on 2026-08-13 against the installed CLI on macOS 26.5.2 arm64 with tmux 3.6a, in a throwaway firstmate home on a private tmux socket, never against a live home and never with a user-scope hook.
+
+Mechanism facts established first, in a separate throwaway workspace:
+
+| Question | Method | Result |
+| --- | --- | --- |
+| Can `stop` block? | hook exits 2 | No. The turn ended normally; Cursor's blocked-response mapper returns `{}` for the `stop` step. |
+| Can `stop` force one turn? | hook returns `{"followup_message":...}` | Yes. A genuine second turn ran and answered. |
+| Can `stop` park? | hook sleeps, then returns a follow-up | Yes. It is awaited; a 20s sleep held the boundary and the follow-up landed after it. |
+| What is `loop_count`? | four consecutive follow-ups, then a real user message | `0,1,2,3`, then `0` again. It counts follow-up-driven stops since the last real user message. |
+| Does `loop_limit` bind? | `loop_limit: 2` with an always-follow-up hook | Yes. The hook was invoked at `loop_count` 0 and 1 and never at 2. |
+| Does a captain message terminate an existing park? | captain message typed during a 600s park | No. Cursor leaves the park running, and without a baton an older park can still deliver after the captain turn's next `stop` has started another park. |
+| Does Cursor load `.claude/settings.json`? | Claude-shaped `SessionStart`, `PreToolUse`, `Stop` in the same workspace | `SessionStart` and `PreToolUse` fired with a CURSOR-shaped payload carrying `cursor_version`; `Stop` did not fire. |
+
+The integration itself is exercised by the opt-in guard:
+
+```sh
+FM_CURSOR_PRIMARY_LIVE_E2E=1 tests/fm-cursor-primary-live-e2e.test.sh
+```
+
+Observed output:
+
+```text
+harness: cursor-agent 2026.08.11-e8db854
+ok - cursor primary: the sessionStart hook takes the fleet lock as the Cursor process itself
+ok - cursor primary: the run-tier session start completes every stage

+ok - cursor primary: the park owns exactly one arm cycle with a live watcher beacon
+ok - cursor primary: the captain keeps control and the older park stands down after the next stop claim
+ok - cursor primary: an away-mode escalation is delivered, confirmed, and processed
+```
+
+The live run proved that session start acquires the fleet lock through Cursor's structural process identity in `bin/fm-cursor-lib.sh`; `tests/fm-session-lock-ancestry.test.sh` pins the same ancestry path portably.
+It also proved that Cursor's `autoarm` supervision model lets the mid-turn pull guard accept a fresh beacon after the between-turn watcher closes; `tests/fm-guard-stale-banner.test.sh` pins that model-aware verdict.
+The baton is claimed only by the next `stop`, so an actionable close before that claim can still produce one real follow-up from the sole existing park; durable wake handling is idempotent, and any older park still running after the claim stands down.
+Cursor's `beforeSubmitPrompt` step could close that exact window because it fires once on a real captain message and not on hook-driven follow-ups, but registering it is deliberately deferred alongside `preCompact`.
+
+Away-mode delivery needed no daemon change once the composer reader was correct for Cursor; [`runtime-backends.md`](runtime-backends.md#composer) owns that evidence.
+
+Cursor compaction instruction refresh is DEFERRED and not shipped, so a Cursor primary does not re-emit its digest after a compaction.
+Two static facts decided that: `PreCompactRequestResponse` carries only `user_message`, and `preCompact` is absent from the `additional_context` step set (`index.js` @ 4814884), so the step cannot inject a digest and any delivery has to be routed through a later boundary.
+A staged-then-delivered design is rejected because carrying a digest across two concurrently running `stop` hooks can deliver it twice or strand it indefinitely, while closing those races enlarges a critical section inside a hook Cursor awaits at the turn boundary.
+Native `preCompact` firing was not observed because a real compaction could not be forced in the isolated session, so the surface has no empirical basis yet.
+It is therefore recorded as uncovered in the same sense as the Codex interactive TUI, and `tests/fm-cursor-primary.test.sh` asserts `preCompact` stays unregistered so it cannot return unnoticed without its own design and evidence.

+## 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`.
+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.
+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, 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.
+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.
+An acknowledged episode does not freeze the generation, because the next downtime after it opens an episode of its own.

+# tests/fm-composer-matrix-live-e2e.test.sh - the live composer-matrix guard
+# (live-harness-optin family; task fm-composer-thin-adapter-refactor-r1).
+#
+# The shared composer classifier's shape catalogue (bin/fm-composer-lib.sh) is
+# built entirely from vendor-rendered signals, so per
+# .agents/skills/firstmate-coding-guidelines it must be proven against the
+# REAL harnesses: a stub can only confirm the assumption already written into
+# the stub. This guard launches every INSTALLED verified harness idle in an
+# isolated tmux server and requires the real fm_tmux_composer_state to reach
+# `empty`, failing loudly with the harness name and version. It also proves:
+#   - the strict blank-row posture live: a plain shell pane with a blank
+#     cursor row must classify unknown and defer injection;
+#   - the zellij false-positive regression live (when zellij is installed): a
+#     pane whose content changes for reasons unrelated to submission must NOT
+#     report a delivered send, and a real claude-in-zellij `dump-screen
+#     --ansi` capture must classify empty through the zellij thin adapter.
+#
+# Run explicitly with FM_COMPOSER_MATRIX_LIVE=1. No prompt is ever submitted
+# to any harness, so no model tokens are spent. An absent harness is reported
+# explicitly and skipped; a run that verified nothing fails rather than
+# passing vacuously. Refresh docs/verification/runtime-backends.md ("Composer
+# classification matrix") from this guard's output after any harness upgrade.
+#
+# Folder trust: harnesses are launched with the repo root as cwd, which the
+# operator's machine has normally already trusted; a trust dialog is a real
+# unreadable-composer state and correctly fails that harness's check.

+#
+# Cursor's identity, liveness, and busy checks are HARNESS-DEPENDENT: their
+# verdicts come from what the vendor emits (a process name, an env marker, a
+# transcript record). This suite pins the LOGIC with real processes, real
+# symlink trees, and real transcript files and NO cursor installed, so CI
+# enforces it everywhere; the live-harness guard in
+# tests/fm-harness-liveness-drift-live-e2e.test.sh is what catches vendor drift
+# against a real cursor-agent. Neither replaces the other.
+#
+# The load-bearing contracts:
+#   1. `agent` and `node` are far too generic to trust by name. Cursor identity
+#      requires Cursor's own name or install tree in the path or argv[0].
+#   2. An unrelated `node`/`agent` pane classifies `other`, which the liveness
+#      callers fold into `ambiguous` - NEVER `dead`.
+#   3. Cursor's env marker outranks an inherited CLAUDECODE, because cursor does
+#      not clear it and whichever marker is tested first wins.
+#   4. The transcript fold brackets a turn: a trailing turn_ended is idle, a
+#      later role:user is busy, and an unresolvable binding is unknown.

+# Opt-in live guard for Cursor Agent CLI as a firstmate PRIMARY.
+#
+# The Cursor primary integration rests on facts only the real cursor-agent can
+# answer: that its `stop` hook is awaited so a park can hold the turn boundary,
+# that a returned followup_message genuinely starts another turn, that
+# `sessionStart` carries additional_context into model context, that Cursor's own
+# process appears in the session-lock ancestry, and that an idle Cursor composer
+# can be proven empty so an away-mode escalation can be delivered. A stub can
+# only confirm the assumption already written into the stub, so this exercises
+# the installed binary end to end.
+#
+# tests/fm-cursor-primary.test.sh and the Cursor cases in
+# tests/fm-tmux-agent-liveness.test.sh are the portable regressions that run
+# everywhere; this is the harness-and-credential-gated counterpart. Run it after
+# every Cursor upgrade and before trusting refreshed per-harness evidence in
+# docs/verification/supervision.md and docs/verification/runtime-backends.md.
+#
+# Isolation: a throwaway firstmate home under a temp dir, a private tmux socket,
+# and a Cursor workspace Cursor has never seen. It never touches the fleet's tmux
+# server, never writes a user-scope or global hook, and never runs against a live
+# home. Cursor still records its own per-project transcript under
+# ~/.cursor/projects/<slug of the temp path>, which is keyed to the throwaway

+# Behavior tests for Cursor Agent CLI as a firstmate PRIMARY
+# (docs/turnend-guard.md, docs/sessionstart-nudge.md,
+# docs/supervision-protocols/cursor.md).
+#
+# Four layers, all hermetic over temp dirs with real processes and NO cursor
+# installed, so CI enforces them everywhere:
+#   HOST GUARD  - bin/fm-hook-host-lib.sh, and each tracked Claude-shaped hook
+#                 entrypoint standing down on a Cursor-delivered payload, which
+#                 is what keeps a Cursor primary from running every covered
+#                 event twice.
+#   PARK        - bin/fm-turnend-guard-cursor.sh, the stop-hook park: its
+#                 follow-up sources, its double loop bound, its bounded repair
+#                 nag, and its post-claim supersession contract.
+#   SESSION     - bin/fm-sessionstart-cursor.sh, which injects the digest at
+#                 sessionStart.
+#
+# The park runs as a child of a fake harness (a bash symlink named cursor-agent)
+# whose pid holds the fixture home's session lock, so the real Cursor ancestry
+# path in bin/fm-session-lock-lib.sh is exercised rather than stubbed.
+# tests/fm-cursor-primary-live-e2e.test.sh is the opt-in guard against a real
+# cursor-agent. Neither replaces the other.

+# Behavior tests for permanent fork-main integration.
+#
+# These fixtures use real local Git repositories to prove the load-bearing
+# properties without touching the live fork, its remotes, secondmate homes, or
+# no-mistakes service:
+#   - explicit and reversible origin=fork/upstream=official topology;
+#   - startup probes upstream only from a validated topology, and reports a
+#     half-migrated one loudly on every startup instead of skipping it;
+#   - rerere enabled with autoupdate off and inherited by standalone homes;
+#   - self-update stays fast-forward-only while reporting a separate upstream
+#     integration need;
+#   - manifest-driven divergence health preserves raw git-cherry signals while
+#     attributing validation and governance artifacts without failing them;
+#   - an upstream-accepted divergence retires with re-provable Git evidence that
+#     outlives the merge which made git cherry blind to it;
+#   - upstream merges are prepared only in isolated candidates, preserve live
+#     origin/main on conflicts, require per-unit re-justification, and reuse a
+#     recorded resolution without staging it;
+#   - fork-target no-mistakes setup proves the ordinary registration unchanged;
+#   - fork divergence briefs deliver the worker rules through the executable
+#     launch-input path;
+#   - topic integration and discard conflicts require receipt-bound continuation.

-**Primary-session guard fact (verified 2026-07-04, Claude Code 2.1.201; preserved 2026-07-08, Claude Code 2.1.204; Stop-owned auto-arm revalidated 2026-07-24, Claude Code 2.1.219).**
+**Primary-session guard fact.**
+[`docs/turnend-guard.md`](../../../docs/turnend-guard.md) owns the current mechanism, and [`docs/verification/supervision.md`](../../../docs/verification/supervision.md#turn-end-guard) owns dated evidence.
 This is separate from the per-task crewmate turn-end hook above (that one just `touch`es a marker file in a task's own `.claude/settings.local.json`).
 The firstmate PRIMARY's own `.claude/settings.json` registers two Stop hooks: `bin/fm-turnend-guard.sh --claude` and the Stop-owned auto-arm `bin/fm-claude-stop-autoarm.sh` (`asyncRewake: true`, `timeout: 28800`), and exiting the guard with status 2 plus stderr reliably forces the model to continue.
-Claude Code's stdin payload to a Stop hook carries a `stop_hook_active` boolean that is `true` when the current stop attempt follows ANY stop-hook-driven continuation, including `asyncRewake` rewakes; the primary guard therefore ignores it in `--claude` mode and uses the cooperative claim/epoch check plus a bounded re-block budget instead, while the codex-mode default still treats it as a one-block loop guard.
+Claude Code's stdin payload to a Stop hook carries a `stop_hook_active` boolean that is `true` when the current stop attempt follows ANY stop-hook-driven continuation, including `asyncRewake` rewakes; the primary guard therefore ignores it in `--claude` mode.
+The current owner above defines its shared session-ownership boundary, one-shot escalation after two identical no-claim blocks, and separate bounded progression for verified automatic failures; the codex-mode default still treats `stop_hook_active` as a one-block loop guard.
 A project-level `.claude/settings.json` only takes effect when Claude Code's project root is that exact directory - it does not walk up from a subdirectory looking for one, so firstmate launches the primary from the repo root.
 After those settings are loaded, hook command resolution is still cwd-sensitive because Claude Code runs commands through `/bin/sh` against the session's current cwd; keep the tracked commands anchored through `"$CLAUDE_PROJECT_DIR"/bin/...` and see `docs/turnend-guard.md` for the verified Stop-hook details.
-Claude Code's primary watcher protocol is Stop-owned: the auto-arm hook fires on every Stop and foregrounds `bin/fm-watch-arm.sh` when the home is eligible and still needs supervision, and its exit-2 `asyncRewake` rewake is the wake; the model drains and handles wakes but never runs a routine re-arm command.

 Cursor's `bin/fm-turnend-guard-cursor.sh` hook is the same between-turns shape in one synchronous step: it parks the awaited `stop` hook on the arm wrapper and translates an actionable close into one `followup_message`, with a generation baton that makes an older park still running after the next `stop` claim stand down instead of leaking a stale duplicate wake.
 The existing turn-end guard remains the final backstop for every harness-engine protocol, with pi-signed sharing Pi's protocol, the `--claude` mode cooperating with the auto-arm claim, and Cursor's `--cursor` mode rendering a block as one bounded follow-up because its `stop` step cannot be blocked.

 In the default Codex mode, a true value lets the second stop finish after one forced continuation.
 
 Claude runs the guard with `--claude`, which ignores `stop_hook_active` and cooperates with the Stop-owned auto-arm.
+Before applying the supervision predicate, Claude mode applies the auto-arm's session-lock boundary: when another proven-live harness session owns `state/.lock`, this lock-refused session is read-only, so its guard exits without mutating the lock owner's block budget.
+Missing, malformed, stale, and self-owned session locks remain on the ordinary guarded path.
 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, `state/.claude-autoarm.lock` has a live `autoarm` role owner whose eventual failure must exit 2, or `state/.claude-autoarm-epoch` contains a fresh actionable rewake owned by this event epoch.
 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 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).
-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.
+When none of those proofs appears and no automatic-failure state exists, the first no-claim observation blocks for that session and evidence signature.
+On the second genuinely identical observation, the guard emits exactly one captain-facing `systemMessage` question and ends the continuation loop itself.
+Every later unchanged Stop passes silently through `state/.turnend-claude-escalated`, while any evidence-signature change resets the count, including task or process-source identities, queued-delivery state, Relay or AFK state, and auto-arm epoch outcome.
+Only a supervision need that disappears during the claim wait without leaving a queued wake clears the episode before passing.
+A verified automatic failure retains the separate `FM_CLAUDE_TURNEND_BLOCK_BUDGET` progression (default 3, below Claude's 8-block override) and its stronger attended alarm.
+In Claude mode, positive watcher recovery clears the block budget, one-shot escalation, 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 accounted at most once under the budget lock.
 Whenever both coordination locks are needed, positive auto-arm recovery and the terminal check acquire the auto-arm owner lock before the budget lock.

+The Claude product live path ran with Claude Code 2.1.232 on 2026-08-14.
+Claude's current [hooks reference](https://code.claude.com/docs/en/hooks), read the same day, states that all matching hooks run in parallel, that Stop exit 2 prevents stopping and continues the conversation, and that `asyncRewake` wakes Claude on exit 2; it documents no sibling cancellation that would support the earlier short-circuit explanation.
+The live check deliberately separated the competing session from the lock owner, which is the condition that falsified that earlier hook-order explanation: the blocked Stop produced an auto-arm entry trace naming `gate-live-session-owner`, while a lock-owning Stop delivered `asyncRewake` normally.
+An absent entry trace on the blocked Stop would have falsified the identity-gate diagnosis; a claimed owner cycle without delivered `Stop hook feedback` would have supported the discarded-rewake candidate.

 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, absent lock, or malformed lock keeps the competing hook inert.
+The matching Claude turn-end guard applies the same proven foreign-live-owner boundary: a lock-refused read-only session may finish without consuming the lock owner's guard budget, while the lock-owning session remains the sole mutable supervision owner.
 The stale-owner claim occurs only after the existing AFK and supervision-need gates pass.
+Every auto-arm invocation appends a best-effort entry and selected pre-claim gate to `state/.claude-autoarm-entry-trace`; the hook never waits for its trimming lock and behaves unchanged when diagnostic I/O fails, while successful trimming keeps the volatile trace at 256 lines.
 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 emits one last-resort notice for the continuous failure episode; later consecutive Stop cycles exit 2 to guarantee another Stop-owned retry without repeating the notice until the turn-end guard consumes the attended fail-open.

Subject: [PATCH 04/39] fix(bin): restore upstream ancestry and preserve wake
 status output (#7)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* docs(stow): generalize read-before-write in the public stow skill (#2091)

The public installer-facing stow skill scoped its classify-then-replace
discipline to TODO/BACKLOG items only, so findings routed to a memory file
had no stated rule against a blind append or a wholesale overwrite.

Step 6 now classifies every finding against the destination's current
contents as new, duplicate, superseding, or obsolete, and states the
considered replacement each classification implies. The outcomes follow the
tiered-memory contract already in the file: an obsolete entry is refreshed,
archived, or replaced in a way that preserves its fact, a duplicate folds
into the entry that already carries it, and a superseded body worth keeping
leaves through step 7's existing exits rather than a second recovery
mechanism.

* refactor(composer): one shape owner behind thin capture adapters, whole matrix fixed

Consolidate every composer shape - bordered boxes (all families, geometry,
titled bottom borders), bare agent-glyph rows and their wrap regions,
opencode's left bar, and pi's identity-gated separator pair - into
fm_composer_classify_screen in bin/fm-composer-lib.sh. Adapters now
contribute only a capture and a declarative capability descriptor
(styled/cursor/identity/rows); capability differences change how confidently
a shape is judged, never what the shapes are, so a new harness shape is
teachable in exactly one place.

Correctness fixes landed as part of the consolidation (audit
data/fm-composer-consolidation-audit-s1):
- locale-safe Unicode-space normalization in the shared owner (closes the
  fleet-wide half of #1988; cmux's local byte-exact NBSP case deleted;
  naming converges with PR #1995's normalization primitive)
- muse's bare glyph joins the shared set, unbreaking muse on herdr/cmux/orca
- orca learns the borderless bare shape, drops its backward-paged composer
  window, and can no longer classify a stale startup banner as the composer
- tmux tolerates a titled bottom border, unbreaking grok steering
- the left-bar shape makes opencode readable on every backend
- zellij gets a real classifier through dump-screen --ansi, replacing the
  content-diff submit heuristic that could confirm an undelivered message
  and close a --resolve-key decision (the fleet's only false positive)
- fm-spawn's kimi launch-readiness regex (the fourth shape copy) now routes
  through the shared classifier

The strict blank-row posture applies fleet-wide (captain decision
blank-row-injection-posture): no positive container proof = unknown = defer,
replacing tmux's permissive blank-cursor-row rule. Away-mode injection was
re-validated end to end on real tmux (defer on partial input and unproven
rows, clean delivery with swallowed-Enter retry into proven-empty
composers). The tmux submit core gains a baseline-idle turn-started
conversion so pi steering stays confirmed while its working screen hides
the composer; busy conversion without that baseline remains forbidden.

Plain-capture backends now degrade a glyph row carrying trailing text to
unknown instead of a false pending, per the approved capability rule.

Portable regressions pin the full byte-capture matrix from the audit under
a UTF-8 locale and LC_ALL=C, the strict-vs-permissive divergence, and
deliberate signal separation; the opt-in live guard
(tests/fm-composer-matrix-live-e2e.test.sh) verified every installed
harness against the real classifier, recorded in
docs/verification/runtime-backends.md.

* feat(bin): add deterministic condition->action watch adapter on the process-event channel

Register a (condition, action) pair once with bin/fm-procevent-when.sh and the
existing process-to-event runner polls the condition tokenlessly, fires the
action at most once on a stable true, and wakes firstmate exactly once with the
captured outcome - instead of burning an agent turn per re-check.

The pair is stored privately under state/when/ and hash-bound by a trust record
the same way fm-check-register.sh binds a custom check, so a mutated spec is
refused without executing anything. A durable exclusive fired marker claimed
before the action makes restarts and re-polls unable to double-fire; every
failure path (mutated spec, condition error past budget, expired deadline,
failed action, uncaptured earlier fire) ends in a terminal captured outcome
that wakes firstmate rather than a silent retry. Eligibility stays a firstmate
judgment: only exact, safe, reversible actions may be bound, and judgment-
needing or destructive actions keep the wake-and-decide flow.

* fix(bin): honor a decision key stated after the verb colon (#2202)

The open-decisions fold only recognized a [key=<slug>] token between the
verb and the colon (needs-decision [key=x]: note). The common worker
shape with the colon first (needs-decision: [key=x] note) silently
folded its stated key into the shared "default" bucket, so two open
decisions could collapse into one record and fm-send --resolve-key <x>
refused to close the decision it plainly named.

A complete token at the head of the note is now an equivalent stated-key
position for every keyed verb, shared by the whole-file and incremental
folds through the one _fm_decision_key owner. The documented
before-colon position wins when both are present, a token deeper in the
note stays prose, a bare keyless line still folds to "default", and a
stated-but-malformed slug is rejected rather than rewritten to
"default". A consumed note-head token is stripped from the note so both
positions yield identical records, and the incremental fold version is
bumped so persisted cursors folded under the old interpretation are
rebuilt from the authoritative log.

Fixes #2109

* fix(bin): prevent watcher recovery acknowledgement livelock (#2212)

* fix(bin): keep a recovery acknowledgement valid across republication

A watcher cycle that opened and closed while the model handled its drained
wakes minted a fresh recovery generation, which invalidated the exact
acknowledgement the drain had just printed. That acknowledgement then consumed
nothing, so the marker stayed pending and every later arm spent its whole cycle
re-announcing the same recovery instead of supervising - a livelock the home
could not leave on its own.

A downtime publication now reuses the generation of an outstanding handling
episode, so a close during the handling window cannot orphan the printed
acknowledgement. The acknowledgement itself separates its two facts: queue-row
consumption is bound to the monotonic --ack-through sequence and always
happens, while only retiring the episode is bound to --recovery-generation. A
generation that moved on is a non-fatal result that names its own remedy
instead of a refusal that consumes nothing.

* no-mistakes(review): Preserve recovery generations and consume stale acknowledgements safely

* no-mistakes(document): Document sequence-bound recovery acknowledgements

* feat(fmx-respond): consume Relay conversation chains (#2206)

* feat(fmx-respond): consume in_reply_to_chain conversation context

The relay's poll payload can carry in_reply_to_chain, an oldest-first
transcript of the surrounding conversation, but the mention-handling
procedure only ever read the immediate in_reply_to parent, so referents
like "this" in a standalone mention stayed unresolvable even when
context was delivered.

Teach fmx-respond to read the chain when present (optional and
backward-compatible: often absent today, kind label not required),
resolve referents against the whole transcript, and extend the
untrusted-content framing to every chain entry including the upcoming
kind=history entries. Document the field's wire shape in
docs/configuration.md as the firstmate-side owner.

* no-mistakes(document): Document Relay chain context ownership

* fix: parse decision verbs before status metadata tags (#2280)

* fix(bin): strip every bracket tag, not just [key=...], from a status verb

status_line_verb only stripped a leading "[key=...]" token before the
colon, so a remote secondmate reply's leading "[corr=...]" correlation
tag stayed glued onto the returned verb word ("needs-decision
[corr=...]" instead of "needs-decision"). The open-decisions fold's
verb match then silently failed to recognize the line at all, so
fm-send --resolve-key refused to close a decision that was plainly
open on the status line.

Generalize the parser to strip every "[name=value]" tag before the
colon, in any order and count, so local and remote replies fold
identically.

* no-mistakes(document): Clarify status metadata verb parsing

* fix(bin): collapse duplicate supervision wakes (#2287)

* fix: collapse duplicate supervision wakes without losing legitimate updates

One remote-secondmate note produced two handling turns (a procevent check
wake published before autohandle, then a signal wake for the same mirrored
bytes), already-ingested replays such as a cursor-loss whole-log recapture
still woke with nothing to do, this home's own bookkeeping closes (fm-send
--resolve-key, the pending-reply escalation close, the captain-held
transfer) re-woke the session that wrote them, and turn-ended-only wakes
were annotated with already-announced status lines that looked like fresh
progress.

Dedup rules, each at its layer's one owner:
- fm-procevent.sh: an adapter may declare 'self-announcing'; the runner
  then applies first and publishes a check wake only for what remains
  unhandled. fm-procevent-remote-reply.sh declares it: the mirrored status
  append is the single announcement, so a fully applied capture publishes
  nothing and a byte-identical replay stays completely quiet. All other
  adapters keep strict publish-before-apply.
- fm-wake-lib.sh: fm_wake_signal_sig/seen_path/seen_current now own the
  watcher's signal signature and .seen-* marker format, plus
  fm_wake_status_append_self_announced, the guarded bookkeeping append
  that advances the marker only over exactly its own bytes and fails
  toward waking on any pending or interleaved foreign write.
- fm-send.sh, fm-pending-reply-lib.sh, fm-decision-hold.sh: bookkeeping
  closes go through that guarded append; escalation opens stay plain
  appends because a new blocker must wake.
- fm-wake-lib.sh annotations: a historical (turn-ended-only) row skips its
  status annotation only when the file's signature provably matches the
  seen marker; anything unannounced keeps annotating.
- fm-classify-lib.sh: a kind=secondmate task's status signal is never
  absorbed as provably-working, because that stream is the routed-reply
  channel the parent must read.

Also fixes a pre-existing exit-path deadlock the regression run reproduced:
a TERM inside a recovery-marker critical section left fm_lock_try_acquire
spinning against this same process's abandoned hold; a self-held lock is
now reclaimed (a subshell still waits on its parent's live hold).

Regression tests drive the real wake functions and executables in both
directions: each duplicate case collapses, while a new remote reply, new
decision, new blocker, merge result, failure, first status change, and a
later different note on the same task all still wake.

* feat: add Cursor CLI crew harness (#2238)

# Conflicts:

* fix(composer): read cursor-agent's reverse-video placeholder as idle

cursor-agent renders its idle composer placeholder dim (SGR 2) but paints the
cell under the terminal cursor in reverse video (SGR 0;7). Reverse video is
neither dim nor a dark truecolor foreground, so the shared ghost stripper keeps
that one character and an idle composer reduces to a lone `P`. Judged on its
own, that remnant reads `pending` on a genuinely idle pane, which defers
away-mode escalation indefinitely on the styled cursorless backends.

Teach the ONE fleet-wide classifier the shape instead of adding an adapter-local
copy: register `→` as an agent prompt glyph so the composer row is structurally
findable at all (without it the bottom-most shape is a stale shell prompt echo
in the scrollback), add both verified placeholders to the idle set, and consult
the styling-independent plain row when the styled row is only a remnant.

The plain-row branch demands the remnant be a proper, strictly shorter substring
of a plain row matching a fully anchored placeholder. Real typed text is
uniformly bright, so stripping leaves it equal to the plain row and it stays
`pending` - verified live against a pane where the typed text was exactly the
placeholder string.

Verified live on cursor-agent 2026.08.11-e8db854; the regression pins the real
captured bytes and asserts the remnant survives stripping, so the case cannot go
vacuous if the stripper later learns SGR 7.

* feat(cursor): narrow cursor identity and order its marker before CLAUDECODE

Cursor ships two executable names - `cursor-agent` and the legacy alias `agent`
- and runs as a bundled node script, so tmux reports the pane command as a bare
`node`. Neither `agent` nor `node` can be trusted by name, so identity gets one
owner in bin/fm-cursor-lib.sh that demands cursor's own name or install tree in
the path or argv[0], from the structural signal only. Probing an arbitrary pid's
executable during a liveness poll would execute a stranger's binary, which is
the hazard that rule exists to close.

Two consequences wired up:

Detection. cursor-agent does NOT clear an inherited CLAUDECODE, so a cursor
worker launched under a claude primary carries both markers and whichever is
tested first wins. The cursor markers are ordered ahead of the CLAUDECODE check;
fm-spawn additionally clears foreign markers at the launch boundary. Both are
kept deliberately - launch sanitization only covers sessions fm-spawn started,
while the ordering also covers a cursor session started by hand. Verified live
that CURSOR_INVOKED_AS is set on the agent process and CURSOR_AGENT=1 on the
child/tool processes fm-harness.sh actually runs as.

Pane liveness. A cursor pane now classifies `agent`. An unrelated node or agent
stays `other`, which the liveness callers already fold into `ambiguous` rather
than `dead`, so a stranger's node pane is never reported agent-free.

Resolution prints the STABLE launcher rather than the canonical target: identity
is proven through canonicalization, but cursor's canonical path carries a
version its own auto-update replaces, and pinning that would strand a task on a
version that can vanish.

The regression drives the two identity signals apart - a cursor-named executable
outside any cursor tree, and a non-cursor-named alias inside one - and asserts
each carries a verdict alone, so no single vendor string is load-bearing. Its
negative controls are real spawned processes, not fixtures.

Verified live on cursor-agent 2026.08.11-e8db854.

* feat(cursor): classify cursor busy state from its own turn transcript

Cursor shipped as "unknown cursor-unverified" on the premise that it exposes no
semantic turn lifecycle, only a rendered "Working" footer. That premise is
wrong: cursor-agent persists an append-only JSONL transcript per conversation
and brackets every submitted turn with a role:user open and a typed turn_ended
close. Verified live on 2026.08.11-e8db854, including the interrupt path, where
Escape closes the turn with status "aborted" - so this source covers manual
interruption, which Claude's Stop hook does not.

That makes it a genuine pull source in the muse mould rather than the rendered
text the redesign forbids: no writer, no arm, no gen, nothing seeded that could
never be cleared. Cursor's `ctrl+c to stop` footer stays out of the verdict, and
herdr's narrower native streaming state cannot stand in for it either.

Binding deliberately does not reconstruct cursor's workspace-slug directory
name. That slug collapses path separators, so rebuilding it would be a guess
that could bind the wrong pane; cursor records the exact absolute workspace path
in each project's .workspace-trusted, and the binding matches on that. A
conversation recorded as prior at spawn is excluded, so a relaunch in a reused
worktree folds its own turn rather than its predecessor's. Requiring a unique
remaining conversation keeps zero and several both unknown, because neither
proves anything about the current turn.

The regression pins the fold with real transcript files and asserts the
dangerous direction stays closed: an unresolvable binding, a record-free file,
an unclaimed workspace, and a workspace-path PREFIX all read unknown, never
idle. The prefix case uses an opaque fixture slug so a slug-rebuilding
implementation cannot pass it.

* feat(cursor): make the cursor launch runnable and give it lifecycle control

Five gaps that together kept a cursor crewmate from being drivable end to end.

Launch. The template invoked `cursor agent`, but `cursor` is not the CLI - the
installed names are `cursor-agent` and the legacy alias `agent` - so the command
could not run at all on a machine with a normal cursor install. It now resolves
through the verified owner, which also refuses a spawn loudly instead of leaving
a pane that dies with command-not-found and reads as a wedged worker.

Session binding. fm-spawn writes state/<id>.cursor-session so the busy fold can
find this pane's transcript, and teardown removes it.

Lifecycle control. No cursor PR touched fm-control-lib.sh, so
`fm-control <id> interrupt|exit|relaunch` could not drive a cursor worker at
all. Verified live: interrupt is a single Escape, exit is /exit, and cursor does
NOT repollute its composer with the cancelled prompt, so unlike muse it needs no
clear key. Secondmate is refused, matching the spawn refusal.

Submit acknowledgement. cursor parks its terminal cursor outside its composer,
so the composer verdict on tmux is always `unknown` and a submit could never be
acknowledged from the composer alone. The submit core's existing idle-to-busy
transition covers that case, but only if the pane's busy footer is recognised,
so cursor's `ctrl+c to stop` joins the harness-less default union the submit
cores read. The TOKEN is matched rather than the spinner verb: the same version
rendered both `Working` and `Running` in consecutive turns.

Bootstrap. A configured cursor crew harness with no cursor executable is now a
loud MISSING diagnostic rather than a first-spawn failure, and it accepts either
installed name.

Interrupt cancellation is deliberately left unconfirmed. The transcript does
type an aborted close, but its post-interrupt write latency measured as
variable - sometimes seconds, sometimes not within twenty - so a claim built on
it would be unreliable. Normal turn completion is prompt, which is what the busy
fold actually depends on.

Two inherited tests are corrected rather than deleted: the busy test asserted
cursor could have no semantic source, and the launch test pinned the literal
`cursor agent` string. Both now pin the verified behaviour, including that the
launch never allocates a second worktree.

name), listed six Grok model ids of which the live catalog now returns two, and
recorded busy state, exit, interrupt, and skill invocation as unverified.

Replaced with what was measured against 2026.08.11-e8db854, including the two
facts most likely to be rediscovered painfully: cursor runs as a bundled node
script so its pane title is a bare `node`, and it parks its terminal cursor
outside its composer, which makes the tmux composer verdict permanently
`unknown` by design rather than a defect to chase.

Model ids now route to `--list-models` for the account instead of a fixed list,
since that list is exactly what drifted.

The live drift guard covers cursor, resolving it through the same verified owner
fm-spawn uses and passing --trust so the probe cannot hang on the workspace
prompt. Run against every installed harness: 8 checked, all alive, with cursor
reporting title='node' foreground=[.../cursor-agent] - the drift shape this
guard exists to catch.

* refactor(composer): move the delivery busy footers to the shared owner

The per-harness rendered busy footers lived in bin/fm-tmux-lib.sh under
FM_TMUX_* names, so cursor's `ctrl+c to stop` signature - and every other
harness's - was reachable only from tmux. That placement was wrong on its own
terms: herdr, zellij, cmux, and orca run the same harnesses and face the same
question these footers answer, which is whether a submitted Enter actually
landed. Nothing about the signature is tmux-specific.

Moved verbatim into bin/fm-composer-lib.sh, the shared composer/delivery owner
every backend already sources, and renamed to FM_DELIVERY_* so the names stop
claiming a scope they never had. All five adapters now reach cursor's signature;
verified per adapter rather than assumed.

The boundary the move must not blur is stated where it now lives: this is a
DELIVERY guard, never a worker-state source. Confirming a keystroke landed is a
different question from asking what a worker is doing, and bin/fm-busy-lib.sh
remains the semantic owner that forbids classifying a harness from rendered
text. Cursor still classifies only from its transcript fold, which is already
backend-agnostic because it folds a file rather than reading a pane - the same
verdict on all six backends.

The old FM_TMUX_* aliases are dropped rather than kept as dead shims: nothing
outside the moved block referenced them except fm-busy-lib.sh's grok fallback,
which now reads the new name. The documented operator override, FM_BUSY_REGEX,
is untouched.

Also removes a dead duplicate CURSOR_INVOKED_AS check in bin/fm-harness.sh,
unreachable behind the marker check above it.

* fix(composer): bound a bare composer's wrap region at a half-block rule

A live cursor crewmate on herdr classified its IDLE composer as `pending`, and
fm-send consequently exited 1 with "delivery unconfirmed" on a message that had
actually landed. The cause is not cursor-specific.

Herdr draws a composer's top and bottom rules with the half-block glyphs U+2584
and U+2580 rather than the box-drawing family. fm_composer_row_has_edge knew
only the box-drawing set, so no box was detected; the composer was found as a
BARE row, and its wrap region - which extends while rows are non-blank and carry
no structural edge - walked straight through the composer's own closing rule and
swallowed the model and path footer below it. That footer is real text, so the
region classified pending on a genuinely idle pane.

Teaching the shared edge detector the half-block glyphs bounds the region at the
closing rule. Measured on the captured bytes of a real herdr cursor pane: the
same capture that read `pending` now reads `empty`.

This is a shared shape-path change, so it is deliberately narrow - it adds
glyphs to the edge vocabulary and changes no verdict logic - and the whole
composer and backend suite is green, including the other harnesses' herdr
fixtures.

The regression pins the real captured shape and asserts the footer content is
genuinely present, so the case cannot pass vacuously if the region were ever
bounded for some unrelated reason.

* fix(herdr): confirm a cursor submit from the rendered-footer transition

Herdr's composer-shape fix made an idle cursor pane classify `empty`, but
`fm-send` still exited 1 with "delivery unconfirmed" on messages that had
actually landed. Live measurement found the second, independent cause.

Herdr reports a cursor pane `agent_status=blocked` in EVERY state - idle,
mid-turn, and after - so the submit path's idle-baseline native confirmation is
structurally unreachable for cursor and every send falls into the composer
branch. That branch reads cursor's mid-turn composer row, which renders its own
`Add a follow-up` placeholder beside a right-aligned `ctrl+c to stop`. That
token is composer content, so the verdict is `pending` on a composer holding no
user text at all, and the Enter-retry budget then reports pending.

The escape is the same semantic signal the native path uses, read from the
pane's verified busy footer instead of native agent-state, and it is the
rendered-footer twin of the tmux submit core's turn-started confirmation: an
idle-to-busy transition ACROSS our Enter proves the harness accepted the
submission. The baseline is taken before the first Enter and only when the
native baseline was not legibly idle, so the idle-baseline path still never
reads pane content and a pane already mid-turn before we typed keeps reporting
`pending` rather than borrowing another turn as proof of this delivery.

The composer verdict is deliberately NOT relaxed. A right-aligned status token
on the composer row stays content for every other caller, including the
away-mode pre-injection guard, and the shared cursorless submit core is left
untouched so zellij, cmux, and Orca keep the behavior their own follow-up owns.

Verified live on herdr 0.8.0 and cursor-agent 2026.08.11-e8db854 in an isolated
lab session: `fm-send` now exits 0 and the steer executes, interrupt cancels a
running turn, `/exit` stops the agent, and teardown clears the record. All seven
panes of the running default session classify identically before and after the
shape fix, so no other harness regressed.

* fix(bin): require quota-axi 0.1.25 (#2300)

* fix: raise quota-axi floor to 0.1.25 for Cursor CLI quota awareness

Homes on latest main need quota-axi #87 so Desktop-absent CLI machines report a fresh Cursor quota instead of a false sign-in-required.

* no-mistakes(document): Update quota floor documentation pointer

* fix(bin): prevent false Pi watcher alarms during hand-offs (#2304)

* fix(guard): stop the false send-time watcher-down alarm on Pi primaries

On a Pi primary the watcher process is not the liveness signal. The Pi
extension tears the watcher down on every actionable wake and spawns the
replacement itself, so the singleton lock is legitimately unheld between
cycles: every one of the 799 cycles in a live primary's ledger ends with
lock_after=pid:none, and a live capture caught the guard verdict flipping to
no-watcher during one hand-off with the beacon 63s old.

bin/fm-guard.sh classified Pi as a persistent-watcher harness, which demands a
live identity-matched lock holder at all times, so any guarded command landing
in a hand-off painted the full WATCHER DOWN - SUPERVISION IS OFF banner and
told firstmate to repair a cycle the extension already owns and is restoring.

Add an extension supervision model for pi and pi-signed. A live
identity-matched watcher stays the ordinary healthy state; an unheld lock is
healthy only while the beacon is fresh within grace AND a live Pi session
provably owns continuity - both primary extensions recorded in their state
markers at their current on-disk builds by the process named in state/.lock,
with that process still alive. Without that proof the banner fires exactly as
before, so an unloaded, version-drifted, or exited Pi session is loud
immediately and a cycle the extension never restores is loud once the beacon
passes grace. The queued-wake warning, the PID-strict turn-end guard, and
every other primary's detection are untouched.

Fold session-start's duplicate Pi marker predicate into the shared library so
the ownership contract has one owner.

* no-mistakes(document): Document Pi watcher hand-off supervision

* feat: support Cursor Agent CLI as a primary harness (#2305)

* feat(cursor): add Cursor Agent CLI primary hooks, park supervision, and session start

Register a tracked project-scope .cursor/hooks.json for Cursor's stop,
sessionStart, preCompact, and preToolUse steps.

bin/fm-turnend-guard-cursor.sh owns Cursor's turn boundary as a park: it
foregrounds the watcher arm, holds the boundary open until an actionable close,
and returns that wake as one follow-up. Exit 2 is a silent no-op on Cursor's
stop step, so the adapter never uses it. The follow-up loop is bounded twice,
by Cursor's own loop_limit and by the payload's loop_count.

bin/fm-sessionstart-cursor.sh delivers the digest as additional_context at
sessionStart, and stages it for the next turn boundary at preCompact, which
cannot inject context.

Cursor also loads the tracked Claude settings, so bin/fm-hook-host-lib.sh lets
each tracked Claude-shaped entrypoint stand down on a Cursor-delivered payload
rather than running every covered event twice.

bin/fm-tmux-lib.sh reclassifies a Cursor pane's composer cursorlessly, because
Cursor parks its terminal cursor outside the composer, which restores a genuine
composer-empty proof and unblocks away-mode escalation delivery.

* feat(cursor): make Cursor Agent CLI a verified primary harness

Resolve Cursor in the session-lock ancestry through bin/fm-cursor-lib.sh, which
a Cursor primary needs before it can hold its own home lock, and classify its
stop-hook park under the autoarm supervision model so the mid-turn pull guard
stops reporting a healthy between-turns watcher as down.

Read a Cursor pane's composer cursorlessly on tmux, gated on Cursor's own
structural process identity, which restores a genuine composer-empty proof and
lets away-mode escalations reach a Cursor primary with no daemon change.

Lift the secondmate refusals in bin/fm-spawn.sh and bin/fm-control-lib.sh now
that the supervision protocol exists and is recorded.

Cover the whole surface with a portable regression over real processes, an
opt-in live guard against the installed cursor-agent, and dated per-harness
evidence.

* docs(cursor): record Cursor as a verified primary across the owning surfaces

Update the turn-end guard, session-start, arm-seatbelt, cd-guard, watcher
continuity, architecture, configuration, README, and harness-adapters owners,
and add dated live evidence to the supervision and runtime-backend verification
records. Correct the recorded Cursor tmux composer verdict: the cursor-anchored
read is still blind, but the composite reader is no longer unknown.

Lift the remaining remote-secondmate refusal missed in the previous commit, and
add the new libs to the existing fixtures that copy a fixed dependency list.

* refactor(cursor): name the park's stand-down condition for both its causes

Also record that Cursor's preCompact firing itself is not yet live-verified,
while the static evidence that it cannot inject context, and the staging path
that follows from it, both are.

* test: give the pretool fixtures their new dependency and one lint owner

The cd-guard fixture copies a fixed dependency list and now needs the shared
hook-host predicate. Both pretool suites also asserted cleanliness with a bare
shellcheck call, a second and weaker copy of the lint definition that
bin/fm-lint.sh owns: it omits --external-sources, so it failed the moment these
checkers sourced a shared library. They now delegate to that owner.

* test: assert the cursor secondmate contract instead of its removed refusal

A cursor secondmate now launches, so the suite asserts what its park actually
needs: --trust so the home's project hooks load at all, its own home pinned as
the workspace, and the autoarm supervision model inherited across the launch.

* revert(cursor): cut preCompact staging from this change

Carrying a compaction digest across two concurrently running stop hooks kept
producing races that could deliver it twice or strand it indefinitely, and
closing them kept enlarging a critical section inside a hook Cursor awaits at
the turn boundary. Native preCompact firing was never observed either, so the
surface has no empirical basis yet.

Remove the adapter, its registration, its staged path in the park, and its
tests, and record the surface as deferred and uncovered alongside the Codex
interactive TUI. A regression now asserts preCompact stays unregistered so it
cannot return without its own design and evidence.

This change ships the proven core only: the turn-end follow-up park, the
run-tier session start, and away-mode delivery.

* feat(bin): add decline and repair paths for decision holds (#2330)

* feat(bin): add unrouted close paths to the captain decision gate

A captain who declines a held decision leaves no follow-up work to route,
so `resolve` could not express that answer: it requires at least one
`--routed-to` task. The only way to close such a hold was a direct
`tasks-axi done`, which never writes the durable resolution record the
completion gate reads, so the originating investigation could no longer
pass `verify` and its cleanup stayed blocked.

Add two close paths that route no work:

- `decline` closes an actively held hold with a recorded captain decision
  and no routed task. It refuses while any task is still blocked by the
  hold, because releasing routed work without recording it is `resolve`'s
  job.
- `repair` records the missing resolution block on a hold that was already
  closed outside this script. It never reopens a hold and never clears a
  dependency edge, and it refuses a hold that is still actively held.

Both require a non-empty captain decision file and share `resolve`'s
digest-based retry identity, so an exact retry is idempotent while a
changed decision is rejected. The recorded body now also names which path
closed the hold, and each routed entry regains its own line.

The gate itself is unchanged: an unanswered decision still fails
completion and blocks teardown, and neither new path can close a hold
without the captain's recorded word.

* fix(bin): require captain-hold provenance before repairing a decision

`repair` checked only that the backlog item was kind captain and Done, so
an ordinary captain-kind task that was never held for the captain could be
closed, repaired, and then pass the completion gate.

tasks-axi keeps `hold_kind` through a close, so it is the surviving proof
that an identity really was a captain hold. Require it before writing the
resolution record, and cover the case in the gate regression.

* feat: add max Calm presentation level (#2334)

* feat(calm): add a max presentation level that hides mid-turn working notes

Calm's home-local preference becomes a three-state level instead of a
boolean: "off" is stock Pi, "on" is today's Calm, and "max" is Calm plus
hiding the assistant text of messages the model did not end its response
with. `/calm max` selects it from any state, a plain `/calm` steps max
back to ordinary Calm and otherwise keeps the existing on/off cycle, and
any other argument keeps that cycle too.

`config/calm` now persists "max" as its own literal value, so a session
start, resume, fork, or reload restores the stored level rather than
treating it as unrecognized and dropping to off.

The hide rule keys on Pi's intrinsic per-message stopReason: "toolUse",
or "length" with tool calls present. Streaming ("pending") text is never
filtered, because suppressing it would also stop a genuine reply from
streaming. The existing assistant layout adapter filters the blocks out
of the same shallow presentation copy it already uses for collapsed
thinking, so the message, model context, session storage, /export, and
delivery are untouched and a hidden mid-turn row collapses to zero
height. The new "assistant-working-note" class keeps that choice in the
visibility policy owner, where ordinary Calm keeps it visible.

* no-mistakes(document): Clarify Calm max persistence and taxonomy

* feat(calm): hide mid-turn working notes by default (#2339)

* feat(calm): make hiding mid-turn working notes the ordinary Calm state

Calm collapses back to the two-state on/off toggle it was before the max
presentation level, with max's hide rule promoted into ordinary Calm.
Calm on now hides mid-turn assistant working notes in addition to what it
already hid, and the /calm command parses no argument again.

The hide rule itself is unchanged: assistant text is removed from the
shallow presentation copy when the message's own stopReason is "toolUse",
or "length" with tool calls present. Streaming ("pending") text is never
filtered, so a genuine reply still streams. The message, model context,
session storage, /export, and delivery remain untouched.

config/calm persists only "on" and "off" again, but the reader still maps
a persisted "max" to on so a home upgraded from the removed level keeps
Calm on instead of dropping to off.

The mid-turn hide is now default behavior rather than an opt-in level, so
docs/calm.md documents it for users, docs/configuration.md records the
two written values plus the legacy max mapping, and the feasibility
taxonomy drops its level-scoped wording.

 A unit that is equivalent upstream but no longer has exactly one aggregate patch commit stops the merge instead of retiring, because that single commit is the whole proof boundary.
 It does not push or invoke no-mistakes.
 The worker validates through the fork registration, runs health against the actual post-pipeline head, and opens a fork-main pull request.
+The captain merges that pull request with the regular merge method, never squash or rebase, so the upstream merge remains reachable.
 
 A conflict exits with code 3, leaves the merge and rerere result unstaged, identifies affected manifest units, and writes a worktree-private re-justification receipt.
 Decide whether every affected divergence remains worth carrying before resolving it.

 A queued signal annotation prints every status line still unread at that cursor, while the fleet-wide UNREAD STATUS section prints `note:` lines and reserved-key pending-reply resolutions once even on an empty-queue drain because those verbs never enter the OPEN DECISIONS fold.
 A failed read, output, or concurrent-replacement check prevents the snapshot cursor from advancing across uncertain bytes, and teardown retires a task's manifest row before that task ID can be reused.

 `bin/fm-crew-state.sh <id>` is the cheap current-state read for an actionable heartbeat review: it attributes a no-mistakes run, active or terminal, only when it matches the crew's branch and current code identity, then keeps that run-step authoritative even if the pane has closed.

Subject: [PATCH 08/39] feat(fork): add permanent fork-main integration

Canonical divergence topic for the fork-main integration workflow the
personal fork carries beyond official upstream: the guarded remote
topology and migration, the isolated fork-target validation clone, the
divergence manifest and its health report, the topic integrate and
discard helpers, the upstream merge helper, the startup upstream probe,
and the supporting brief, seed, self-update and documentation surfaces.

Submitted upstream as PR 1944 and retired when that lands.

+  Agent-only procedure for operating Firstmate from a permanent personal-fork main.
+  Use before configuring or reversing Firstmate code remotes, briefing a Firstmate divergence topic, provisioning or using the isolated fork validation registration, integrating or discarding a divergence, responding to UPSTREAM_SYNC output or an upstream-integration required/failed result, preparing an upstream merge, re-justifying its conflicts, or deciding what the fork still carries.
+user-invocable: false
+metadata:
+  internal: true
+---
+
+# fork-main-integration
+
+Load this procedure only when the Firstmate code repository itself uses permanent fork-main integration.
+[`docs/fork-main.md`](../../../docs/fork-main.md) is the operator-current owner of the mechanics, the manifest schema, and the health criteria.
+The script headers own exact mechanics and arguments.
+This file keeps what binds you at the point of action - the prohibitions, the order of operations, and the judgements no report can make for you - and points at that owner for everything descriptive.
+
+## Safety boundaries
+
+- `origin` is the personal fork and `upstream` is official.
+- Never migrate the captain's operating checkout as a side effect.
+  Run `bin/fm-fork-remotes.sh plan`, show the reverse command, and obtain concrete captain confirmation before the live `apply` command.
+- Never reconfigure the ordinary no-mistakes registration to target fork main.
+- Normal live-home remote migration must prove that registration before and after the Git change.
+  The `--no-registration` exception belongs only to provisioned remote code roots that never validate changes, and is never a retry or bypass after a registration error.
+- Provision a separate private integration clone only through `bin/fm-fork-integration.sh`.
+  Stop if ordinary-registration isolation cannot be proven before and after init.
+- Never restart or update the shared no-mistakes service from this workflow.
+- Live homes remain fast-forward-only consumers of validated fork main.
+  Real upstream and topic merges happen only in isolated candidates.
+- Keep `rerere.autoupdate=false`.
+  A replayed resolution must remain unstaged and reviewable.
+- Never force-push or rewrite a published topic or pull-request branch.
+- Never habitually merge upstream or fork main into a divergence topic.
+  Do so only for a concrete API dependency, a real merge conflict, or an upstream maintainer request.
+- Every fork-main PR still requires the captain's explicit merge approval.
+
+## New divergence intake
+
+1. Scaffold the Firstmate ship brief with `--start-ref upstream/main` so unrelated fork divergences cannot enter the upstream pull request.
+   That generated brief loads this procedure for the worker and directly carries the no-rewrite, no-routine-merge, and official-upstream validation rules through the typed launch input.
+2. Run the ordinary no-mistakes path against the official-upstream registration.
+3. Preserve the upstream pull request as the delivery and review artifact.
+4. Before fork integration, ensure the canonical `fm/divergence/<id>` topic contains one aggregate non-merge patch commit relative to upstream.
+   `git cherry` is patch-by-patch and cannot prove that a multi-commit topic equals one upstream squash commit.
+5. Never rewrite a published multi-commit PR branch to satisfy step 4.
+   Create a fresh one-commit canonical divergence topic and retain the original head as the manifest-linked delivery artifact.
+6. Create an isolated candidate from fetched fork main in the private integration clone.
+7. Run `bin/fm-fork-topic.sh integrate` with a concrete retirement condition and complete path list.
+   On exit 3, settle the retain decision, resolve and stage the product conflict, and run receipt-bound `bin/fm-fork-topic.sh continue` with the complete decision file.
+8. Drive no-mistakes from that integration clone, run health against the post-pipeline head, open the fork-main PR, and require fork CI green.
+9. Tell the captain the full fork PR URL and concise local outcome.
+10. Merge only after the captain says so, using the regular merge method so the inner topic merge remains reachable.
+11. Run `/updatefirstmate` after landing so safe homes fast-forward from validated fork main.
+
+A vague retirement reminder is not a valid manifest condition.
+Use a falsifiable statement such as "Upstream ships equivalent endpoint identity validation" or "This compatibility path is no longer reachable on every supported backend".
+
+## Upstream review disposition
+
+A pending divergence whose PR closes without merge must not remain pending.
+Choose one of two outcomes in the next validated fork integration:
+
+- Reclassify it to `rejected-but-retained` through `bin/fm-fork-topic.sh disposition` because current evidence still justifies the behavior.
+- Discard it because its retirement condition is true or the evidence no longer supports carrying it.
+
+Upstream rejection does not automatically remove useful running behavior.
+A correctness or security finding that applies locally is stronger evidence than the earlier green run and requires an immediate fix or discard.
+
+## Upstream integration
+
+Handle `UPSTREAM_SYNC: required` or `upstream-integration: required` as work for the main primary, never a secondmate or remote code root.
+Coalesce duplicate notifications behind one open integration task.
+
+`UPSTREAM_SYNC: fork topology is not validated: <requirement>` is a different problem and never starts a merge.
+This home has an `upstream` remote but has not completed the explicit migration, so the upstream movement probe was skipped and the line repeats on every startup until it is fixed.
+Report the named requirement to the captain and, once they confirm, complete the migration through `plan` then the live `apply` command, or reverse it - never migrate `origin` silently to clear the line.
+
+1. Ensure the private fork registration passes `bin/fm-fork-integration.sh check`.
+2. Create an isolated candidate branch at fetched `origin/main` from the private integration clone.
+3. Run `bin/fm-fork-merge.sh prepare`.
+4. On a clean result, inspect the emitted `git range-diff --remerge-diff` review and health result before starting no-mistakes.
+5. On exit 3, treat every named conflict as a divergence re-justification decision before resolving files.
+6. Load `ask-user-authority` before deciding whether routine authority can answer a re-justification.
+   A material behavior expansion, destructive choice, security-sensitive choice, or captain-owned product trade-off still goes to the captain.
+7. Resolve files only after the decision is settled, write the complete `firstmate.fork-rejustify.v1` decision file outside the candidate working tree, and run `continue`.
+   If the settled decision is complete removal, use the receipt-bound upstream `abort`, then the independent topic `discard` path, land that candidate, and retry upstream preparation instead of continuing the conflict.
+8. Drive no-mistakes through the private fork registration and process every gate.
+9. Require fork CI green and captain merge approval.
+10. Use the regular merge method, then run `/updatefirstmate`.
+
+A replayed rerere result supplies only the previously accepted file resolution, never the answer to whether the divergence is still worth carrying; the unmerged index is the barrier that keeps that decision explicit, so never let a replay stand in for it.
+
+## Health and relevance
+
+Use `bin/fm-fork-status.sh` for the local answer and add `--refresh` only when live remote and PR evidence is needed.
+After no-mistakes, use the post-pipeline candidate command in [`docs/fork-main.md`](../../../docs/fork-main.md); a bare invocation reads the fork remote rather than proving candidate `HEAD`.
+Its own errors, signals, and exit status are the machine verdict, and [`docs/fork-main.md`](../../../docs/fork-main.md) states how it classifies raw `git cherry` facts and what makes it unhealthy.
+
+Never describe the fork as healthy when that report is not.
+The one judgement the report cannot make is yours: a pending unit that is aging without action is not a healthy fork, however clean the machine verdict.
+
+Run the `git range-diff --remerge-diff` command the report prints for every unit the latest upstream merge touched.
+It is a human review surface, not machine state.
+
+## Discard
+
+Prepare discard only from an isolated branch at fetched fork main:
+
+```sh
+bin/fm-fork-topic.sh discard --id <id> --repo <isolated-worktree>
+```
+
+Any product-file conflict reopens re-justification and leaves a receipt-bound merge or revert operation.
+Resolve the decision and files, write the complete `firstmate.fork-rejustify.v1` decision outside the candidate, then run `bin/fm-fork-topic.sh continue --decisions <file> --repo <isolated-worktree>`.
+Validate the actual post-pipeline candidate through the private fork registration and require captain approval for its fork-main PR.
+Never reset or rewrite fork main to remove a divergence.
+
+Git remembers a reverted merge as unwanted ancestry.
+To restore discarded behavior, revert the revert or introduce a genuinely new topic version.
+Do not merge the old topic blindly.

 This is secondmate-only: crewmate/scout model resolution is untouched by this file.
 
 This section is the single owner of the secondmate sync and inherited-local-material propagation contract; `AGENTS.md` sections 3 and 4 point here.
+When the primary uses validated fork-main topology, also load `fork-main-integration` before provisioning.
+A standalone local home inherits the primary's exact fork `origin`, official `upstream`, local main tracking branch, and reviewable rerere settings; a linked home already shares those Git facts.
+Before inheritance mutates an existing standalone home, local seeding snapshots its complete Git config and remote-ref topology and restores both if any later seed step fails.
+A remote provision receives those validated URLs explicitly and establishes the same topology in its code root before the persistent home is attached.
+The helpers refuse a partial or contradictory source topology rather than guessing, and `/updatefirstmate` leaves remote code roots as independent fast-forward consumers rather than upstream integrators.
 Before a local launch, `fm-spawn.sh --secondmate` locally fast-forwards the home to the primary firstmate checkout's current default-branch commit when it is safe; dirty, diverged, or in-flight homes launch unchanged with a warning.
 The locked session-start deferred network stage runs the same bootstrap sweep for every live local secondmate home, discovered from `state/<id>.meta` records with `kind=secondmate` (`data/secondmates.md` only backfills `home=` for older records).
 That no-fetch path is a purely local fast-forward of tracked files, never an origin fetch, and it never touches the gitignored operational dirs, so a secondmate's backlog, projects, and in-flight work are never disturbed; a linked worktree advances immediately, while a standalone clone that lacks the target receives firstmate updates through `/updatefirstmate`'s origin refresh.

    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`).
 3. **Wake queue** - when locked, presents the durable wake queue 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.

 - **Event-driven, zero-token supervision** - a bash watcher sleeps on the fleet and wakes the first mate only when something needs you; verified primary harnesses also get a turn-end backstop that blocks or follows up on a blind stop when work is under way and supervision is not live.
 - **Optional Relay** - opt in with one local `.env` pairing token so firstmate can answer your public mentions on X and Discord alike, act on normal reversible mention requests through the same lifecycle as chat requests, acknowledge spawned work, and post up to three public-safe completion follow-ups within seven days for genuine milestones and the final outcome without changing non-Relay behavior; a final reply promised in a thread becomes durable state that is reconciled from disk, so a restart or a compacted conversation cannot lose it; dry-run preview records would-be replies and dismissals locally before go-live.
 - **Strict project boundary** - the first mate is read-only over your projects except for the narrow guarded and captain-approved operations authorized by [hard rule 1](AGENTS.md#1-identity-and-prime-directives), including fleet sync's guarded safe branch pruning; crewmates make every other project change behind the configured merge authority.

 The path check is authoritative: \`git rev-parse --git-dir\` and \`git rev-parse --git-common-dir\` can help inspect the repo, but they do not prove you are outside the primary checkout.
 If the top-level path is the primary checkout or not the worktree you were launched in, STOP - do not branch or commit here - append \`blocked: launched in primary checkout, not an isolated worktree\` to the status file and stop.

+# Prepare, continue, or abort one validated upstream-to-fork-main merge candidate.
+#
+# Usage:
+#   fm-fork-merge.sh prepare [--repo <isolated-worktree>]
+#   fm-fork-merge.sh continue --decisions <json> [--repo <isolated-worktree>]
+#   fm-fork-merge.sh abort [--repo <isolated-worktree>]
+#   fm-fork-merge.sh range-diff [--repo <isolated-worktree>]
+#
+# prepare requires a clean named feature branch whose HEAD exactly equals
+# origin/<default>. It fetches origin and upstream, then runs
+# `git merge --no-ff --no-commit upstream/<default>` only in that isolated
+# candidate. The operating main checkout is never a target.
+#
+# A conflict is a relevance decision, not a mechanical merge failure. prepare
+# leaves the candidate conflict intact, writes a worktree-private receipt under
+# its Git directory, lists matching manifest units, and exits 3. Rerere may have
+# populated known working-tree resolutions, but topology setup keeps
+# rerere.autoupdate=false, so they remain unstaged. continue refuses until every
+# listed unit has one explicit retain decision with a reason and all
+# conflicts have been resolved and staged.
+#
+# A successful merge updates fork-divergences.json in the merge commit itself:
+# a unit whose one aggregate patch Git proves equivalent to a reachable upstream
+# commit is moved from divergences to retired_upstream with that proof, and one
+# bounded sync record captures the pre-merge fork/upstream refs and touched
+# units. The proof stays because after this merge upstream is an ancestor of
+# fork main, which empties git cherry's equivalence search space. It then
+# commits the two-parent merge, runs the human `git range-diff --remerge-diff`
+# review, and validates the candidate manifest against HEAD. It never pushes,
+# opens a PR, force-updates a ref, or invokes no-mistakes; the task worker owns
+# validation and delivery through the isolated fork-target registration.

+# Configure and validate Firstmate's fork-main Git remote topology.
+#
+# Usage:
+#   fm-fork-remotes.sh check [<repo>]
+#       Require origin=<fork>, upstream=<official>, distinct URLs, main tracking
+#       origin, rerere.enabled=true, and rerere.autoupdate=false.
+#   fm-fork-remotes.sh plan <fork-url> <upstream-url> [<repo>]
+#       Read only. Validate the requested migration and print the exact apply and
+#       reverse commands. Never infers a fork owner or changes Git configuration.
+#   fm-fork-remotes.sh apply <fork-url> <upstream-url> --confirm [--no-registration] [<repo>]
+#       Migrate only an exact upstream-as-origin checkout, or validate an already
+#       migrated one. Prints the reverse command before changing anything. Both
+#       URLs must answer a read-only ls-remote preflight. The ordinary
+#       no-mistakes registration must prove official remote plus personal fork
+#       unchanged before and after migration. --no-registration is reserved for
+#       provisioned remote code roots that never validate changes themselves.
+#       Never force-pushes or changes a branch or working-tree file.
+#   fm-fork-remotes.sh reverse <fork-url> <upstream-url> --confirm [<repo>]
+#       Restore the official repository as origin and retain the personal fork as
+#       a remote named fork. Never changes commits or working-tree files.
+#   fm-fork-remotes.sh inherit <source-repo> <target-repo>
+#       Provisioning-only convergence for a new standalone secondmate clone.
+#       A linked worktree already shares the source config and is a no-op. An
+#       unrelated target remote is refused, never overwritten.
+#
+# apply/reverse require the literal --confirm token because changing origin on a
+# captain's operating checkout must be surfaced and approved, never performed as
+# a side effect of startup or self-update. The remote-root-only
+# --no-registration exception is an explicit provisioning input, not a fallback
+# after a no-mistakes error. apply explicitly leaves
+# rerere.autoupdate off: rerere may populate a repeated resolution in the working
+# tree, but it must remain unstaged for review.
+#
+# Every network call runs with GIT_TERMINAL_PROMPT=0. Remote home provisioning
+# calls apply non-interactively while holding the provision lock, so an
+# unconfigured credential helper must fail the run rather than block it on a
+# username prompt that no one can answer.

+# integration merges. A raw non-upstream commit outside those topics is a visible
+# signal, not automatically a carried divergence or a health failure. Descendant
+# validation fixes and manifest-only governance commits are attributed as
+# integration artifacts. retired_upstream records add the one equivalence fact
+# Git can no longer recompute after an integration merge, and every one of them
+# is re-proved here before its patch leaves the factual non-upstream count.
+#
+# --refresh fetches origin and upstream and verifies recorded GitHub PR
+# dispositions with gh-axi. Without it, the report is network-free and uses
+# local refs plus recorded dispositions. gh-axi's current API serializer is
+# parsed as one complete, untruncated scalar envelope rather than compared as
+# raw stdout.
+# --check-upstream is the cheap self-update and startup probe: it reports whether upstream is already an ancestor of the fork
+# and never merges or changes a working-tree file; --refresh still updates the
+# remote-tracking refs it reads. --facts-only keeps rising divergence count
+# visible but makes the exit status depend only on Git/manifest consistency and
+# superseded debt; candidate preparation uses it when adding or retiring an

+# Integrate, reclassify, or discard one canonical fork divergence topic in an
+# isolated fork candidate.
+#
+# Usage:
+#   fm-fork-topic.sh integrate --id <id> --summary <sentence>
+#     --class <pending|rejected-but-retained|private> --topic <ref>
+#     --retire-when <falsifiable-condition> --path <path-or-prefix>...
+#     [--pr-url <github-pr-url> --pr-disposition <open|rejected>]
+#     [--repo <isolated-worktree>]
+#   fm-fork-topic.sh disposition --id <id>
+#     --class rejected-but-retained --pr-disposition rejected
+#     [--repo <isolated-worktree>]
+#   fm-fork-topic.sh discard --id <id> [--repo <isolated-worktree>]
+#   fm-fork-topic.sh continue --decisions <json> [--repo <isolated-worktree>]
+#
+# integrate requires a clean named candidate branch at fetched origin/main and a
+# canonical topic whose `git cherry upstream/main <topic>` result contains
+# exactly one non-equivalent commit. This one-aggregate-patch invariant is what
+# makes upstream squash/rebase equivalence measurable. It merges the topic with
+# --no-ff --no-commit, writes the manifest entry into that same merge commit,
+# commits, and validates the candidate against HEAD.
+#
+# disposition is the supported governance-only pending-to-rejected transition.
+# It updates the class and recorded pull-request disposition atomically in one
+# candidate commit, then validates that actual HEAD. The commit is reported by
+# health as a manifest-governance artifact, never as a carried divergence.
+#
+# discard derives every delivered merge that integrated the named topic, whether
+# direct or in one regular pull-request candidate range, and applies their
+# mainline-parent-one inverses as one `git revert --no-commit` sequence. It
+# removes the manifest unit and commits the complete discard once, so intermediate
+# manifest states never enter history.
+#
+# A product conflict in integrate or discard exits 3, leaves Git's merge or
+# revert state intact, and writes a worktree-private receipt binding the branch,
+# original HEAD, merge or revert head, manifest, and unaffected index. continue
+# requires a complete firstmate.fork-rejustify.v1 decision, resolved/staged
+# conflicts, and that exact receipt. It finishes every queued revert before the
+# one manifest update, then validates health against the completed candidate.
+#
+# Neither command pushes, opens a PR, force-updates a ref, or invokes
+# no-mistakes. The task worker validates and delivers the candidate through the
+# isolated fork-target registration.

 For a remote route, the configured code root updates from its own origin on that host before the persistent home fast-forwards to the code-root commit.
 The update is fast-forward only: dirty, diverged, offline, and off-default targets are reported and left untouched.
 Local homes share the guarded fast-forward helper, while remote updates delegate the same safety decision to the configured host through the generic transport.

+A permanent fork-main home keeps that same consumer path instead of weakening it into an in-place merge.
+Its `origin` is already validated fork main, while official `upstream` integration is prepared in an isolated candidate, reviewed with Git's patch-workflow primitives, validated through a separate fork-target no-mistakes registration, and merged only through a captain-approved fork pull request.
+The operating home and every secondmate then consume that result through the ordinary fast-forward path.

+# Fork main integration
+
+A Firstmate home can run from a personal fork's `main` as a permanent integration branch while continuing to receive the official repository's changes.
+This is a maintained divergence workflow, not a temporary staging branch.
+The fork is healthy only when its named divergence set stays small, turns over, and trends down.
+
+## Remote topology
+
+The guarded topology uses two remotes and requires each remote's fetch and push URLs to name the same place.
+
+- `origin` is the personal fork and local `main` tracks `origin/main`.
+- `upstream` is the official repository and is pull-only by policy.
+- Linked task worktrees and leased local secondmate homes share the repository's common Git configuration and refs.
+- Newly provisioned standalone local and remote secondmate homes inherit the validated URLs through their provisioning owners.
+- Remote code roots consume fork main and never integrate official upstream independently.
+
+A fresh home initializes no-mistakes while the official repository is still `origin`, naming the personal fork with `--fork-url`.
+It then uses `gh-axi repo fork --remote` so GitHub CLI makes the fork `origin` and renames the official remote to `upstream`.
+Run the guarded `plan` and confirmed `apply` below afterwards; the already-renamed case validates the exact URLs, proves the no-mistakes registration, and establishes the branch and rerere policy without renaming again.
+This preserves the ordinary no-mistakes registration as the upstream-submission lane while giving the operating checkout the correct fork topology.
+
+Changing `origin` on a running captain home is never a startup or self-update side effect.
+Inspect the plan first:
+
+```sh
+bin/fm-fork-remotes.sh plan <fork-url> <upstream-url>
+```
+
+The plan prints the exact apply and reverse commands.
+Run the apply command only after the captain confirms that concrete live-home migration.
+The apply path requires a literal `--confirm`, validates both URLs before changing names, proves the ordinary no-mistakes registration still names official upstream plus personal fork before and after migration, enables repository-local rerere, and leaves rerere autoupdate explicitly off.
+A failed post-migration registration proof restores the original Git topology rather than reconfiguring or retrying no-mistakes.
+The `--no-registration` form is reserved for provisioned remote code roots that never validate changes themselves; never use it to bypass a registration failure in an operating primary.
+The reverse path restores official upstream as `origin`, retains the personal fork as `fork`, and never rewrites a commit.
+
+## Two validation targets
+
+Ordinary topic validation and fork integration validation must not share one mutable no-mistakes registration.
+The ordinary registration keeps official upstream as its remote and the personal fork as its push target.
+A private integration clone uses the fork as its no-mistakes remote so its pull requests target fork main.
+
+Inspect or provision that clone with:
+
+```sh
+bin/fm-fork-integration.sh plan <fork-url> <upstream-url>
+bin/fm-fork-integration.sh ensure <fork-url> <upstream-url> --confirm
+bin/fm-fork-integration.sh check <fork-url> <upstream-url>
+```
+
+The private clone defaults to `data/fork-integration` and therefore stays outside tracked source and project clones.
+Provisioning snapshots the ordinary registration's upstream and fork facts before any init and proves them byte-identical afterwards.
+It refuses an existing mismatch rather than refreshing either registration.
+A no-mistakes error stops the operation and never restarts, updates, or reconfigures the shared service.
+
+## One canonical topic per divergence
+
+Each carried divergence has one canonical branch named `fm/divergence/<id>`.
+Start a Firstmate divergence brief from official upstream rather than detached fork main:
+
+```sh
+bin/fm-brief.sh <task-id> firstmate --mode no-mistakes --start-ref upstream/main
+```
+
+The exact `upstream/main` start ref also makes the generator place the fork worker contract in the brief that `fm-spawn.sh` delivers as its typed launch input.
+That delivered contract loads `fork-main-integration`, forbids rewriting a published topic or pull-request branch, forbids routine upstream or fork-main merges into the topic, and keeps topic validation on the ordinary official-upstream registration.
+The focused regression for this delivered contract is [`tests/fm-fork-main.test.sh`](../tests/fm-fork-main.test.sh).
+
+A canonical new topic has one aggregate non-merge patch commit before its first fork integration.
+This constraint matters because `git cherry` compares patches one commit at a time.
+It recognizes the same one-commit patch after upstream squash or rebase changes its commit ID, but it cannot prove that several topic commits equal one aggregate upstream squash.
+
+Never rewrite a published pull-request branch to manufacture that shape.
+A legacy multi-commit submission gets a fresh one-commit canonical divergence topic, while its original pull-request head remains a linked delivery artifact.
+Use `git range-diff` to review the relationship between the submitted series and canonical patch.
+
+A topic does not habitually merge fork main or official upstream.
+Git's own workflow guidance reserves a downstream merge for a concrete reason, such as an upstream API change reaching the topic or a topic that no longer merges cleanly.
+Fork main is the integration branch and receives upstream regularly.
+The captain's 2026-08-14 ruling requires DAILY official-upstream synchronization.
+
+## Integrate and discard a topic
+
+Prepare a divergence integration only in an isolated worktree of the private integration clone.
+The helper requires fetched fork main as the exact starting point, one `git cherry` non-equivalent commit on the canonical topic, complete manifest path coverage, and a concrete retirement condition.
+
+```sh
+bin/fm-fork-topic.sh integrate \
+  --id <id> \
+  --summary '<one sentence>' \
+  --class <pending|rejected-but-retained|private> \
+  --topic fm/divergence/<id> \
+  --retire-when '<falsifiable condition>' \
+  --path <path-or-directory-prefix> \
+  [--pr-url <full-url> --pr-disposition <open|rejected>] \
+  --repo <isolated-worktree>
+```
+
+The helper merges with `--no-ff --no-commit`, adds the manifest entry to that merge, commits the two-parent result, and validates health against candidate `HEAD`.
+It never pushes or opens a pull request.
+A product conflict exits 3 with Git's merge state intact and a private receipt that binds the branch, original head, topic merge head, manifest, conflict paths, and unaffected index.
+Settle whether the divergence remains worth carrying, resolve and stage the product files, and write a complete `firstmate.fork-rejustify.v1` decision with action `retain` outside the candidate.
+Continue with:
+
+```sh
+bin/fm-fork-topic.sh continue --decisions <file> --repo <isolated-worktree>
+```
+
+The continuation refuses a changed branch, merge head, manifest, unaffected index, incomplete decision, unstaged resolution, or untracked file.
+It writes the manifest entry into the completed merge commit and validates that candidate.
+The worker runs no-mistakes through the isolated fork registration, runs health against the actual post-pipeline head, waits for fork CI, and the captain merges the fork pull request with the regular merge method so the topic merge remains reachable.
+
+Discarding selects only the named topic's integration merges on fork main's direct first-parent history or one regular pull-request candidate range beneath it, then reverts them newest to oldest with mainline parent one:
+
+```sh
+bin/fm-fork-topic.sh discard --id <id> --repo <isolated-worktree>
+```
+
+A manifest-only overlap from a later topic is preserved mechanically while the named entry is removed.
+Any product-file conflict stops for re-justification with a receipt bound to the branch, original head, active revert head, queued integration merges, manifest backup, conflict paths, and unaffected index.
+After settling the remove decision and staging the product resolution, use the same `continue` command above with action `remove`.
+The helper finishes the complete `git revert --no-commit` sequence, collects any continuation commits back into the unpublished candidate, removes the manifest unit, and records product plus governance changes in one final commit.
+The resulting branch still goes through no-mistakes, post-pipeline health, fork CI, pull request, and captain approval.
+
+Git documents an important merge-revert consequence.
+A reverted merge tells later merges that its ancestors are unwanted.
+Re-enabling a discarded topic therefore requires reverting the revert or introducing a genuinely new topic version, not blindly merging the old branch again.
+
+## Manifest
+
+The tracked [`fork-divergences.json`](../fork-divergences.json) file uses schema `firstmate.fork-divergences.v1`.
+Git owns patch facts, and the manifest owns only intent Git cannot know.
+
+Every divergence records:
+
+- a stable ID and one-sentence summary;
+- exactly one class: `pending`, `rejected-but-retained`, `private`, or `superseded`;
+- its canonical topic branch;
+- introduction date;
+- upstream pull request and recorded disposition when it is not private;
+- the concrete falsifiable condition that retires it;
+- every exact path or directory prefix its patch touches.
+
+`pending` means upstream review remains open and therefore pairs only with pull-request disposition `open`.
+`rejected-but-retained` means upstream declined it but current evidence still justifies carrying it, so it pairs only with pull-request disposition `rejected`.
+`private` means it is intentionally not proposed upstream, carries no pull-request record, and should remain small.
+`superseded` is immediate removal debt and must be empty after an upstream integration.
+
+An upstream-sync record keeps the pre-merge fork SHA, previous and incoming upstream SHA, date, touched divergence IDs, and an optional validation pull-request URL.
+Counts are derived from Git rather than copied into the manifest.
+The history stays bounded to the latest 20 integrations.
+
+A `retired_upstream` record is the one exception to deriving facts from Git, because it preserves a fact Git can no longer recompute.
+It keeps the retired unit's ID, canonical topic, summary, retirement date, the fork commit that carried the patch, the upstream commit that carries the same patch, and their shared patch ID.
+Each record is written into the same upstream merge that removes the active divergence entry, so the divergence count can never fall without the evidence explaining it.
+Records are not bounded, because a fork patch stays in history forever and its proof must stay auditable for exactly as long.
+A retired ID is never reused for a new divergence.
+
+Update the manifest in the same fork integration or upstream merge that changes the divergence set.
+A follow-up is not acceptable because a stale manifest looks authoritative.
+
+## Health report
+
+Run the local network-free report with:
+
+```sh
+bin/fm-fork-status.sh
+```
+
+Add `--refresh` to fetch both remotes and compare recorded GitHub pull-request dispositions through `gh-axi`.
+Refresh fails closed when live disposition evidence is incomplete or its response shape is unsupported.
+Add `--json` for schema `firstmate.fork-health.v1`.
+
+The report uses `git cherry upstream/main origin/main` for one fact only: which commits have no equivalent upstream patch.
+The manifest supplies the meaning of what the fork intends to carry, so active patch counts come from each manifest unit's canonical topic rather than every raw `+` line.
+A non-upstream commit outside those canonical patches is a visible signal, not automatically a carried divergence or a failed report.
+A validation fix descending from a recognized topic or upstream integration is attributed as an `integration-path` artifact.
+A manifest-only review-disposition commit is attributed as a `manifest-governance` artifact.
+After no-mistakes, validate the actual post-pipeline candidate because helper-prepared health cannot classify commits that validation added later:
+
+```sh
+bin/fm-fork-status.sh --repo <isolated-worktree> --fork-ref HEAD --facts-only
+```
+
+This candidate-only mode still prints the trend but limits its exit-status verdict to Git and manifest consistency plus superseded debt; do not use it to characterize the running fork as healthy.
+
+The report names active units and canonical patches, all factual non-upstream commits, integration artifacts, informational signals, trend since the previous upstream merge, counts by class, the oldest pending unit, the latest merge's touched units, retirement conditions, every accepted-upstream retirement with its proof, superseded debt, and structural health errors.
+
+A merge revert leaves both the original patch and its inverse in history, so both remain raw `git cherry +` facts after their net effect is gone.
+The status owner excludes a pair from active health only when Git proves the exact reachable `git revert -m 1 <topic-merge>` relationship.
+It reports the excluded count as retired history rather than hiding it.
+
+An upstream-accepted patch is the second exclusion, and it needs stored evidence because Git stops being able to recompute the fact.
+Git documents `git cherry`'s equivalence search space as `<head>..<upstream>`, so once the integration merge makes upstream an ancestor of fork main, that range is empty and the fork's own copy of the accepted patch is a raw `+` fact forever.
+The status owner therefore re-derives each `retired_upstream` record from reachable objects instead of trusting it: the recorded fork commit must still be a carried patch on fork main, the recorded upstream commit must still be reachable from `upstream/<default>`, and both must still hash to the one recorded patch ID.
+Only that independent proof excludes the patch, and the report names every retirement with the fork commit, upstream commit, and patch ID it rests on.
+A record that is stale, contradictory, unproved, or missing leaves its patch counted and reported, never silently excluded.
+PR state, commit messages, branch names, ancestry, and stated intent never retire a patch.
+
+The report is unhealthy when one canonical patch has multiple manifest owners, one canonical topic has several non-equivalent commits, a topic or integration merge is missing, declared paths omit a changed file, a pull-request disposition is stale, a recorded retirement no longer re-proves, any superseded unit remains, or retained canonical patches trend up.
+A manifest unit whose topic has become equivalent upstream is signaled for retirement review rather than misreported as a raw-patch ownership failure.
+An unrepresented non-upstream commit is likewise a signal until an operator classifies its meaning.
+The signal remains named and counted, so this distinction does not hide the Git fact.
+
+`git range-diff` remains a human review tool because Git documents its output as version-unstable and not machine-readable.
+When the latest upstream integration touched a divergence, the health report prints the exact `git range-diff --remerge-diff` command for review.
+Export one topic's portable patch with `git format-patch upstream/main..fm/divergence/<id>`.
+
+## Upstream integration
+
+`/updatefirstmate` keeps live homes fast-forward-only.
+Before the first origin-based fast-forward, each code root with an `upstream` remote must pass the fork topology check exactly once; a failure names the missing fact and the guarded correction before any code commit moves.
+It advances each code root from validated fork `origin/main`, then advances subordinate homes to that root's exact commit without trusting their own origin, and finally reports whether official upstream still needs a separate integration.
+It never merges in the operating checkout.
+
+Locked startup performs the same non-merging need probe as part of its deferred network work and emits `UPSTREAM_SYNC:` only when a validated merge is needed or the check failed.
+It probes at most once per successful 24-hour interval; a failed probe writes no success marker and therefore remains eligible on the next startup.
+That probe runs only once `bin/fm-fork-remotes.sh check` passes.
+A home that has an `upstream` remote but has not finished the explicit migration is reported as `UPSTREAM_SYNC: fork topology is not validated: <first missing requirement>` on every startup, with no probe and no daily marker written, so a half-configured home stays loud until it is corrected or reversed.
+A home with no `upstream` remote at all is classic single-origin and stays silent.
+The main primary owns that work.
+Secondmates and remote code roots do not create competing merges.
+
+Prepare a candidate in an isolated worktree of the private integration clone:
+
+```sh
+bin/fm-fork-merge.sh prepare --repo <isolated-worktree>
+```
+
+A clean result creates a two-parent upstream merge, moves each unit whose canonical patch Git proves equivalent to a reachable upstream commit and whose equivalent patch reverses cleanly from the incoming upstream tip into `retired_upstream` with that proof, records the sync input, runs `git range-diff --remerge-diff`, and validates health against candidate `HEAD`.
+A unit that is equivalent upstream but no longer has exactly one aggregate patch commit stops the merge instead of retiring, because that single commit is the whole proof boundary.
+It does not push or invoke no-mistakes.
+The worker validates through the fork registration, runs health against the actual post-pipeline head, and opens a fork-main pull request.
+The captain merges that pull request with the regular merge method, never squash or rebase, so the upstream merge remains reachable.
+
+A conflict exits with code 3, leaves the merge and rerere result unstaged, identifies affected manifest units, and writes a worktree-private re-justification receipt.
+Decide whether every affected divergence remains worth carrying before resolving it.
+Continue only with a complete decision file:
+
+```json
+{
+  "schema": "firstmate.fork-rejustify.v1",
+  "decisions": [
+    {
+      "id": "example",
+      "action": "retain",
+      "reason": "The accepted behavior still requires this fork-specific guard."
+    }
+  ]
+}
+```
+
+Keep the decision file outside the candidate's working tree, then run:
+
+```sh
+bin/fm-fork-merge.sh continue --repo <isolated-worktree> --decisions <file>
+```
+
+The decision action is only `retain`, and a retained unit remains an active manifest owner even when its historical patch is equivalent upstream.
+An upstream conflict with no manifest path owner uses the explicit `__unowned__` ID and still requires a reason.
+The helper refuses a changed branch, changed merge head, missing decision, short reason, or unresolved index.
+
+If the conflict evidence instead justifies complete removal, settle the stopped operation without publishing a merge:
+
+```sh
+bin/fm-fork-merge.sh abort --repo <isolated-worktree>
+```
+
+Then use `bin/fm-fork-topic.sh discard --id <id>` from that restored candidate, advance fork main through the ordinary validated pull-request path, and retry upstream preparation.
+The receipt-bound abort refuses any branch, head, or merge that differs from the stopped operation and removes its receipt only after Git restores the recorded clean fork head.
+
+Rerere records the accepted resolution and can replay it on the next equivalent conflict.
+Because `rerere.autoupdate=false`, replay changes the working tree but keeps unmerged index stages, preserving the review and re-justification barrier.
+Rerere cannot recover conflict resolutions made before it was enabled.
+
+After the fork pull request lands, `/updatefirstmate` performs only safe fast-forwards from fork main into each validated code root and propagates that exact commit into its local or remote subordinate homes.
+
+## Upstream review after local adoption
+
+Upstream review is evidence, not the local shipping gate.
+A change enters use only after its topic validation, fork merge candidate validation, green fork CI, captain-approved fork pull request, and safe fleet update.
+
+If upstream rejects a useful running change, reclassify it from `pending` to `rejected-but-retained` in the next validated fork integration through the supported interface:
+
+```sh
+bin/fm-fork-topic.sh disposition \
+  --id <id> \
+  --class rejected-but-retained \
+  --pr-disposition rejected \
+  --repo <isolated-worktree>
+```
+
+The helper changes the class and recorded pull-request disposition together, commits the governance transition, and validates candidate health.
+Keep or sharpen its falsifiable retirement condition.
+Do not roll it back merely because upstream declined it, and do not leave it mislabeled.
+
+If upstream review reveals a correctness or security problem that applies locally, prior local validation does not overrule that evidence.
+Fix the topic or use the independent discard path immediately.
+
+When upstream accepts an equivalent patch, `git cherry` removes it from the active patch set even when squash or rebase changed the SHA.
+That equivalence is visible only until the integration merge lands, so the next upstream integration captures it as a `retired_upstream` proof in the same commit that removes the manifest unit, and preserves upstream's implementation.
+A materially edited upstream version can still conflict, which is exactly when range-diff and the retirement condition must decide which behavior remains.

Subject: [PATCH 09/39] fix(bin): make supervision recovery owner-aware and
 durable

Canonical divergence topic for the Claude primary-session supervision fix
the personal fork carries beyond official upstream: session-ownership
alignment for the Stop auto-arm and turn-end guard, a bounded volatile
entry trace that distinguishes a hook that never ran from one that took a
pre-claim gate, one-shot repeated-block escalation, a single supervision
snapshot behind queue warnings, queued delivery treated as a supervision
need until post-handling acknowledgement, and the BASH_SUBSHELL
lock-ownership check stock macOS Bash 3.2 needs because it has no BASHPID.

Submitted upstream as PR 2392 and retired when that lands.

-**Primary-session guard fact (verified 2026-07-04, Claude Code 2.1.201; preserved 2026-07-08, Claude Code 2.1.204; Stop-owned auto-arm revalidated 2026-07-24, Claude Code 2.1.219).**
+**Primary-session guard fact.**
+[`docs/turnend-guard.md`](../../../docs/turnend-guard.md) owns the current mechanism, and [`docs/verification/supervision.md`](../../../docs/verification/supervision.md#turn-end-guard) owns dated evidence.
 This is separate from the per-task crewmate turn-end hook above (that one just `touch`es a marker file in a task's own `.claude/settings.local.json`).
 The firstmate PRIMARY's own `.claude/settings.json` registers two Stop hooks: `bin/fm-turnend-guard.sh --claude` and the Stop-owned auto-arm `bin/fm-claude-stop-autoarm.sh` (`asyncRewake: true`, `timeout: 28800`), and exiting the guard with status 2 plus stderr reliably forces the model to continue.
-Claude Code's stdin payload to a Stop hook carries a `stop_hook_active` boolean that is `true` when the current stop attempt follows ANY stop-hook-driven continuation, including `asyncRewake` rewakes; the primary guard therefore ignores it in `--claude` mode and uses the cooperative claim/epoch check plus a bounded re-block budget instead, while the codex-mode default still treats it as a one-block loop guard.
+Claude Code's stdin payload to a Stop hook carries a `stop_hook_active` boolean that is `true` when the current stop attempt follows ANY stop-hook-driven continuation, including `asyncRewake` rewakes; the primary guard therefore ignores it in `--claude` mode.
+The current owner above defines its shared session-ownership boundary, one-shot escalation after two identical no-claim blocks, and separate bounded progression for verified automatic failures; the codex-mode default still treats `stop_hook_active` as a one-block loop guard.
 A project-level `.claude/settings.json` only takes effect when Claude Code's project root is that exact directory - it does not walk up from a subdirectory looking for one, so firstmate launches the primary from the repo root.
 After those settings are loaded, hook command resolution is still cwd-sensitive because Claude Code runs commands through `/bin/sh` against the session's current cwd; keep the tracked commands anchored through `"$CLAUDE_PROJECT_DIR"/bin/...` and see `docs/turnend-guard.md` for the verified Stop-hook details.
-Claude Code's primary watcher protocol is Stop-owned: the auto-arm hook fires on every Stop and foregrounds `bin/fm-watch-arm.sh` when the home is eligible and still needs supervision, and its exit-2 `asyncRewake` rewake is the wake; the model drains and handles wakes but never runs a routine re-arm command.

 Cursor's `bin/fm-turnend-guard-cursor.sh` hook is the same between-turns shape in one synchronous step: it parks the awaited `stop` hook on the arm wrapper and translates an actionable close into one `followup_message`, with a generation baton that makes an older park still running after the next `stop` claim stand down instead of leaking a stale duplicate wake.
 The existing turn-end guard remains the final backstop for every harness-engine protocol, with pi-signed sharing Pi's protocol, the `--claude` mode cooperating with the auto-arm claim, and Cursor's `--cursor` mode rendering a block as one bounded follow-up because its `stop` step cannot be blocked.
 Its `--restart` mode signals only the watcher recorded in the current home's `state/.watch.lock`, so restarting one home cannot kill sibling secondmate watchers.

+A pull-based guard (`bin/fm-guard.sh`) warns through supervision tool output if the primary checkout is tangled, if work, process-event sources, Relay polling, or queued delivery has an unhealthy model-aware supervision verdict, or if queued wakes still await post-handling acknowledgement.
 The drain script calls that guard after presenting the queue; records remain durable, and may keep the queued-wakes warning visible, until the exact generation-bound acknowledgement printed by the drain succeeds after handling.
 It leads with a prominent bordered tangle banner, while `bin/fm-guard.sh` owns the watcher-down banner and reminder policy so repeated guarded commands stay noisy without reprinting the full banner in the same episode.
-On every verified primary harness, tracked hook integration gives the primary session a push-based backstop: when work, a process-event source, or Relay polling needs supervision and no identity-matched watcher lock with a fresh beacon is live, blocking-capable Stop hooks block and nonblocking turn-end integrations force one bounded follow-up.

 The guard covers the main primary and genuinely marked secondmate homes, exempts child crewmate/scout worktrees, is loop-safe per harness, and is documented in [turnend-guard.md](turnend-guard.md).
 
 A presence-gated sub-supervisor (`bin/fm-supervise-daemon.sh`) extends this for walk-away supervision: the `/afk` skill starts it through the tracked foreground helper `bin/fm-afk-start.sh`, after which the watcher reverts to daemon-managed one-shot mode and the daemon self-handles routine wakes in bash.

@@ -71,13 +72,19 @@ Both payloads carry `stop_hook_active`.
 In the default Codex mode, a true value lets the second stop finish after one forced continuation.
 
 Claude runs the guard with `--claude`, which ignores `stop_hook_active` and cooperates with the Stop-owned auto-arm.
+Before applying the supervision predicate, Claude mode applies the auto-arm's session-lock boundary: when another proven-live harness session owns `state/.lock`, this lock-refused session is read-only, so its guard exits without mutating the lock owner's block budget.
+Missing, malformed, stale, and self-owned session locks remain on the ordinary guarded path.
 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, `state/.claude-autoarm.lock` has a live `autoarm` role owner whose eventual failure must exit 2, or `state/.claude-autoarm-epoch` contains a fresh actionable rewake owned by this event epoch.
 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 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).
-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.
+When none of those proofs appears and no automatic-failure state exists, the first no-claim observation blocks for that session and evidence signature.
+On the second genuinely identical observation, the guard emits exactly one captain-facing `systemMessage` question and ends the continuation loop itself.
+Every later unchanged Stop passes silently through `state/.turnend-claude-escalated`, while any evidence-signature change resets the count, including task or process-source identities, queued-delivery state, Relay or AFK state, and auto-arm epoch outcome.
+Only a supervision need that disappears during the claim wait without leaving a queued wake clears the episode before passing.
+A verified automatic failure retains the separate `FM_CLAUDE_TURNEND_BLOCK_BUDGET` progression (default 3, below Claude's 8-block override) and its stronger attended alarm.
+In Claude mode, positive watcher recovery clears the block budget, one-shot escalation, 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 accounted at most once under the budget lock.
 Whenever both coordination locks are needed, positive auto-arm recovery and the terminal check acquire the auto-arm owner lock before the budget lock.

+Claude's current [hooks reference](https://code.claude.com/docs/en/hooks), read the same day, states that all matching hooks run in parallel, that Stop exit 2 prevents stopping and continues the conversation, and that `asyncRewake` wakes Claude on exit 2; it documents no sibling cancellation that would support the earlier short-circuit explanation.
+The live check deliberately separated the competing session from the lock owner, which is the condition that falsified that earlier hook-order explanation: the blocked Stop produced an auto-arm entry trace naming `gate-live-session-owner`, while a lock-owning Stop delivered `asyncRewake` normally.
+An absent entry trace on the blocked Stop would have falsified the identity-gate diagnosis; a claimed owner cycle without delivered `Stop hook feedback` would have supported the discarded-rewake candidate.

-# registration: a fresh session with in-flight work, no watcher, and a stale
-# session lock can run fm-session-start.sh first; session start reclaims the
-# dead owner; at least two tokenless auto-arm and rewake cycles then complete
-# with zero model-issued arm commands; and the cooperative guard consumes no
-# forced continuation while the hook's launch is healthy.
-# The project and FM_HOME are isolated; Claude keeps using its existing managed
-# authentication. No live fleet home, worktree, or session is touched.

+# Two real Claude sessions share one isolated Firstmate home.
+# The lock-owning session stays active while a read-only competing session ends
+# a turn with work in flight and no watcher. The competing auto-arm must trace
+# its live-owner gate, and its matching guard must let that read-only session
+# finish instead of trapping it in a continuation loop. When the owner ends its

@@ -153,26 +85,6 @@ 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 concurrently in a bounded worker owned by `bin/fm-startup-network.sh` and is reported in the digest's own `NETWORK CHECKS` section.
 When that section reports its checks still in progress it names exactly what is unconfirmed; treat none of those as passed until the result lands, either from `bin/fm-startup-network.sh report` or as a `check: startup-network` wake.
 
-1. **Lock** - acquires the per-home session lock first, before anything mutates shared state, then starts the deferred network 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 - non-executing legacy PR-check migration, 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`).
-3. **Wake queue** - when locked, presents the durable wake queue 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.
-   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.
-   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 `state/.afk` flag; 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 required tools are present and GitHub authentication is good.
 Use `gh-axi` for GitHub, `chrome-devtools-axi` for browser work, and `lavish-axi` for structured decisions or reports; consult current help rather than memorizing flags.

 ## 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.
+Load `fmx-respond` on an `x-mention <request_id>`, `x-mode-error ...`, or `public-followup ...` check wake, before promising a final public reply, whenever session start lists one awaiting delivery, and on every milestone or terminal wake for Relay-linked work.
 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.

 ## Relay (.env)
 
 Relay lets a firstmate instance answer public mentions and act on normal reversible mention requests through firstmate's normal lifecycle.
+Older documentation and some emitted lines call this integration "X mode", and its identifiers retain the `FMX_`, `x-`, and `fm-x-` spellings.
 It covers both public surfaces the relay supports: `@myfirstmate` mentions on X, and mentions of the myfirstmate bot in a Discord server where it is installed.
 Both surfaces are the same opt-in and the same machinery - one pairing token, one relay poll, and one reply path - so everything below applies to Discord mentions unless a line names a platform explicitly.
 It is off unless the firstmate home's gitignored `.env` contains a non-empty `FMX_PAIRING_TOKEN`.

Subject: [PATCH 17/39] feat(fork): accept an upstream issue as a divergence's
 upstream route

The fork now states a problem upstream as an issue and opens a pull request
only once it is confirmed. The divergence manifest assumed the older order, so
a divergence raised that way had no honest classification: `pending` demanded a
pull-request URL we deliberately did not have, `private` asserted an intent we
do not hold, and citing a withdrawn pull request would have recorded a policy
withdrawal as though it were a judgement on the work's merits.

The fix deletes an assumption rather than adding a state. The class already
describes the governance question - is upstream review open, did upstream
decline, do we never intend to propose - and whether that review is a pull
request or an issue is orthogonal to all three. So `pending` now means an open
upstream review by either route, `rejected-but-retained` covers a decline by
either, and no new class, field, count, or aging case appears anywhere.

Accepting a wider value must not mean accepting anything, so the validator
names the two accepted forms explicitly rather than taking whatever parses:
https://github.com/<owner>/<repo>/pull/<number> and the same with /issues/.
An absent or malformed route is still refused for every class but `private`,
which is the check that stops a divergence being registered with no upstream
story at all. The added test exercises that refusal instead of asserting it,
and both guards were confirmed to go red under deliberate weakening: letting an
empty route through, and relaxing the pattern to accept any URL.

`private` is corrected to mean what it can enforce - a decision never to
propose upstream - so it no longer describes an intended-but-unraised
divergence. That misreading is what made a false record look like the only
option.

Known inaccuracy, stated rather than hidden: the field is still named
`upstream_pr` and the flag `--pr-url`, and both now also carry issues.
Correcting them requires rewriting the existing entries in
fork-divergences.json, and fm-fork-topic.sh refuses any divergence topic that
edits that manifest, so the rename cannot travel with this change. No alias or
dual-key reader is added, because two names for one fact would cost more than
one name known to be weak. The rename deserves its own change, moving the data
and the name together; docs/fork-main.md records the inaccuracy and the reason
until then.

Two related collisions with the same PR-first assumption are deliberately left
for their own changes: the validation pipeline opens an upstream pull request
from its own `pr` step, and withdrawal notes claimed retention that could not
be supported. A third is worth noting for its irony - the fork-main tooling
this change edits is itself classified `pending` behind an upstream pull
request, the very model it is being taught to stop assuming.

 The exact `upstream/main` start ref also makes the generator place the fork worker contract in the brief that `fm-spawn.sh` delivers as its typed launch input.
 That delivered contract loads `fork-main-integration`, forbids rewriting a published topic or pull-request branch, forbids routine upstream or fork-main merges into the topic, and keeps topic validation on the ordinary official-upstream registration.
 The focused regression for this delivered contract is [`tests/fm-fork-main.test.sh`](../tests/fm-fork-main.test.sh).
+Fork-only work validated through that ordinary registration skips the no-mistakes rebase step and records that the step was skipped, that its comparison base was official upstream rather than fork main, and the branch's actual commit and file delta against fork main.
+The registration correctly measures the branch against official upstream, which does not carry the fork divergences and therefore reports those fork-only commits as unrelated bundled work.
+This skip is safe because the detector is not blind: it is correctly measuring a different base, and refreshing the mirror cannot add the fork divergences to official upstream.
+The recorded comparison lets a later reader distinguish the intentional skip from a clean rebase.
 
 A canonical new topic has one aggregate non-merge patch commit before its first fork integration.

Subject: [PATCH 19/39] feat(bin): report reclaimable Next.js build output in
 pooled worktrees

Pooled task copies accumulate Next.js build output that nothing removes.
`treehouse return` resets tracked content and leaves gitignored output where
it is, so a returned copy keeps it. On 2026-08-06 that contributed to a home
where every Bash call failed with ENOSPC for several minutes - nothing ran at
all, including df and du, so the problem could not even be measured - and a
coverage run was aborted mid-verification.

bin/fm-next-cache-sweep.sh inspects pooled copies and reports which hold
regenerable build output and how much. It deletes nothing.

Deletion is absent by design, not postponed, and both paths were removed for
proven reasons:

- The sweep cannot prove it owns a pooled copy. Holding a Treehouse lease
  across validation and deletion was the proposed remedy; either acquisition
  mutates the copy it hands out, or nobody has shown a lease covers the whole
  validation-through-deletion window. The proof does not exist today.
- Teardown-side reclamation is structurally unprovable under Treehouse's
  process-bound hold: ownership exists while a shell has its cwd in the
  worktree, and quietness is proven only when no such process remains. Both
  are read off the same observable, so no ordering makes both true at once,
  and exempting the holding shell would exempt a shell that can start a build.

Reclamation therefore depends on a task-lifetime durable lease, which would
make ownership independent of worktree processes. Until then this is
report-only, which is a boundary rather than a verdict about Treehouse.

What the report still buys, against the incident above: it names where the
gigabytes are without touching them, which is what was missing when the
problem could not be measured.

Every ownership input must be proven readable and complete before a copy is
even reported as assessable; anything unreadable, absent, malformed or
indeterminable is recorded as an unassessed verdict rather than skipped. The
header carries an input inventory in which each verdict states what was
checked and what would falsify it, and a falsifier rule governing how those
verdicts are written.

Fork divergence: it assumes a pooled-worktree layout and Next.js projects.

 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 concurrently in a bounded worker owned by `bin/fm-startup-network.sh` and is reported in the digest's own `NETWORK CHECKS` section.
+Every network check a session start owes - GitHub auth, the fork-upstream probe, dead-secondmate relaunch, secondmate convergence, pending handoff delivery, and project clone refresh - runs concurrently in a bounded worker owned by `bin/fm-startup-network.sh` and is reported in the digest's own `NETWORK CHECKS` section.
 When that section reports its checks still in progress it names exactly what is unconfirmed; treat none of those as passed until the result lands, either from `bin/fm-startup-network.sh report` or as a `check: startup-network` wake.
 
-1. **Lock** - acquires the per-home session lock first, before anything mutates shared state, then starts the deferred network 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 - non-executing legacy PR-check migration, 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`).
-3. **Wake queue** - when locked, presents the durable wake queue 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.
-   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.
-   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 `state/.afk` flag; 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.

 ## 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.

-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.

+# Shared discovery and reporting of Next.js build output inside a task worktree.
+#
+# Why this exists: a pooled worktree returns to the pool carrying its Next.js
+# build output, and nothing ever removes it. Measured 2026-08-18: one idle
+# Artemis copy held a 15 GB packages/frontend/.next on a volume with 11 GB free;
+# removing that one directory took free space to 27 GB. An earlier sweep on
+# 2026-08-07 found ~25.6 GB of it spread across eight copies. The output
+# regenerates from source on the next build, so it is the largest reportable
+# disk consumer in the pool.
+#
+# Sourced by bin/fm-next-cache-sweep.sh, which reports build output in copies
+# already sitting idle in the pool. The discovery rule is stated here once.
+#
+# WHAT IS REPORTED. Exactly directories named .next that pass BOTH proofs:
+#   1. git ignores the directory in the repo that contains it
+#      (`git check-ignore`). Tracked content can never match, so no source, no
+#      git data, and no committed fixture is reachable by this rule.
+#   2. its parent is a Next.js app root: a next.config.{js,cjs,mjs,ts,cts,mts}
+#      sits beside it, or the parent's valid package.json names `next` in a
+#      recognized dependency table. This is what makes the claim "regenerable
+#      build output" true rather than assumed - a gitignored directory that
+#      merely happens to be called .next is left alone.
+# Nothing is removed. node_modules, source, and git data are out of reporting
+# scope by construction, not by exclusion list: the walk prunes node_modules
+# and .git outright, and neither could pass proof 2 anyway.
+#
+# OTHER CACHES WERE MEASURED AND DELIBERATELY LEFT OUT. Surveying the whole pool
+# on 2026-08-18 turned up one other large gitignored directory: a project's .tmp
+# scratch root, ~8.7 GB across the copies, holding audit output, coverage JSON,
+# browser recordings, and review artifacts. That is agent work product, not build
+# output - nothing regenerates it - so it is not this rule's business, and the
+# same goes for a `dist` (~102 MB pooled, and tracked in some projects). Every
+# other candidate measured zero: .turbo, .cache, .parcel-cache, .vite, .output.
+# Widening this rule by pattern would trade a large, provable report for a small,
+# unprovable one; add a directory only by naming it and its measured size.
+#
+# Next.js documents .next as the build output directory (`distDir` defaults to
+# '.next') and clears it itself on every production build (`cleanDistDir`
+# defaults to true, preserving only .next/cache). That establishes the output as
+# regenerable without granting this code authority to remove it.
+# A project that sets a custom `distDir` is deliberately NOT discovered: reading
+# a build config to decide what to report would make eligibility depend on
+# untrusted project code. Such a project remains unreported, which is the safe
+# direction to be wrong in.
+#
+# The walk prunes node_modules and .git, and stops descending at each .next it
+# finds, so a nested .next under .next/standalone is reported with its parent
+# rather than counted twice. Measured cost on the largest live Artemis copy
+# (5.1 GB of loose scratch, full node_modules): 214 ms.
+#
+# This library only inspects and reports. The sweep uses pool state, task records,
+# and a clean tree to qualify that report. Sourcing this file grants no authority
+# to remove anything.

+# Report Next.js build output in pooled worktrees that appear unused.
+#
+# This feature is report-only. Teardown-side reclamation was removed as
+# unprovable, not postponed: under Treehouse's process-bound hold, ownership
+# exists while a shell has its cwd in the worktree, but quietness is proven only
+# when no such process remains. Reordering cannot make both proofs true at once,
+# and exempting the holding shell would exempt a shell that can start a build.
+# Every returned copy, including forced-cleanup descendants, therefore retains
+# its build output. This sweep inventories that output and removes nothing.
+#
+# Reclamation depends on `firstmate-durable-worktree-lease` landing. A
+# task-lifetime durable lease makes ownership independent of worktree processes,
+# which is the required boundary for ownership and quietness to hold together.
+#
+# This report-only boundary is provisional, not a verdict about Treehouse.
+# Whether acquisition mutates a copy is filed as the separate scouted experiment
+# `firstmate-treehouse-lease-mutation-probe`, which can safely lease a copy first
+# proven empty and clean. This command does not run or pre-empt that experiment.
+# It is a command a human or firstmate runs; there is deliberately no daemon,
+# watcher, schedule, or disk-pressure trigger behind it.
+#
+# Usage: fm-next-cache-sweep.sh [--dry-run] [<project-dir>...]
+#   --dry-run   retained as a report-only compatibility spelling.
+#   <project-dir>...  inspect and report these project clones' pools.
+#
+# WHAT IT INSPECTS. Only pooled task copies, and only the Next.js build output
+# inside them - bin/fm-next-cache-lib.sh's header owns that discovery rule. The
+# project clone itself is never inspected as a pool copy: firstmate reads its
+# clones and only crewmates change them, and a clone is where nothing builds
+# anyway.
+#
+# A COPY MUST PASS ALL FOUR CHECKS before it is reported as eligible:
+#   1. treehouse reports it `available`. A live dev server rewrites the build
+#      output the moment you delete it, and deleting mid-build is worse than
+#      leaving it alone, so a leased copy is out of scope no matter how idle it
+#      looks. The pool is shared across firstmate homes and treehouse's lease is
+#      the only ownership signal that spans all of them, which is why it comes
+#      first rather than last.
+#   2. No task record names it. This home's state/*.meta plus every registered
+#      secondmate home's, so a copy owned by a task in another home is skipped
+#      even if its lease was somehow released.
+#   3. The tree is clean. Uncommitted work is unlanded work.
+#   4. There are no stashes. A stash is unlanded work that a clean tree does not
+#      show, and nobody is watching an idle copy to notice it disappear.
+# Checks 3 and 4 read git and change nothing. A copy with a proven owner keeps
+# its build output and is reported. An ownership input that is absent,
+# unreadable, malformed, or incomplete refuses reporting at that input's scope:
+# task-record enumeration refuses the whole sweep, and pool or worktree
+# inspection refuses that project before any of its copies are reported.
+#
+# It reports every qualifying directory and its size, and says plainly when it
+# found nothing. There is no flag, environment variable, or target origin that
+# grants this command deletion authority.
+#
+# Exit status is 0 when the inspection completed, 1 when reporting or a project's
+# pool lookup failed (already reported), 2 on a usage or environment error.
+#
+# FALSIFIER RULE - read this before adding or editing any verdict below.
+#
+# A falsifier must name the concrete case that would DEFEAT the check.
+# It must never name the category the check already rejects.
+#
+# A falsifier that restates the check is vacuous: it passes exactly when the
+# check passes, so it can never reveal that the check is too narrow. The test
+# to apply is not "what does this check reject?" but "what would SATISFY this
+# check and still violate the property the verdict claims to establish?"
+#
+# This was learned the expensive way. The verdict governing the project
+# argument carried the falsifier "any non-root argument". A linked worktree IS
+# a root, so it satisfied the falsifier and defeated the check anyway: the
+# check established "is a worktree root" while the property needed was "is the
+# primary clone". The entry passed its own test while the verdict stayed wrong.
+# "A linked worktree, which is a root but is not the primary clone" would have
+# caught it.
+#
+# The same shape defeated the clone exclusion three times, each time because
+# the property established was narrower than the property needed:
+#   `git rev-parse --git-dir` answering        proves a repo is REACHABLE, not that the path is its root
+#   `--show-toplevel` equalling the path       proves the path is A worktree root, not the PRIMARY one
+#   `--absolute-git-dir` = `--git-common-dir`  proves the primary worktree, which is the property needed
+#
+# A quick way to find suspect entries: any falsifier phrased as a negation or a
+# category of what the check tests - "any non-X", "a missing X", "an unreadable
+# X" - is probably restating the check rather than defeating it. Re-derive those
+# first.
+#
+# INPUT COMPLETENESS INVENTORY
+#
+# The contract for every item below is that an absent, unreadable, malformed,
+# ambiguous, or incomplete ownership input cannot produce a determinate answer.
+# A global input refuses the sweep, a project input refuses that project before
+# its plan is applied, and a copy input prevents a positive eligibility verdict
+# while also making its project incomplete.
+#
+# Each source site is identified by file, function, and the exact statement or
+# command that reads it rather than by a numeric line that this inventory itself
+# would immediately invalidate. The inventory was built by tracing every
+# external command and status, command substitution, filesystem predicate and
+# directory entry, file parser, environment or CLI value, Python-to-shell
+# boundary, and summary selector. That input-oriented trace includes implicit
+# omission paths that a syntax search for `continue` cannot find.
+#
+# Every verdict below carries both the observation it rests on and a concrete
+# falsifier: a case that could satisfy the named check while still violating the
+# property that check is meant to establish. Restating the check as "a non-X"
+# is not evidence that the check establishes the broader property.
+#
+# Sweep entry and global ownership inputs:
+# - `bin/fm-next-cache-sweep.sh: startup -> BASH_SOURCE, FM_* overrides, cd,
+#   readable library predicates, and source`. Checked: every failed directory
+#   command substitution is tested, both library paths must pass `-r`, and a
+#   nonzero source status exits before target construction. Falsifier: an
+#   override whose parent cannot be searched, or a readable library whose source
+#   command returns nonzero, reaches target construction as a complete report.
+# - `bin/fm-next-cache-sweep.sh: argument loops -> "$@"`. Checked: the option
+#   case accepts only `--dry-run`, rejects every other dash-prefixed value with
+#   exit 2, and retains non-options verbatim. Falsifier: `--unknown` is retained
+#   as a project, or `-- /path` loses the literal project path before validation.
+# - `bin/fm-next-cache-sweep.sh: target construction -> PROJECT_ARGS,
+#   sweep_project_directories, and TARGETS`. Checked: each target record carries
+#   `explicit-report` or `pool-report`, and any missing or unknown mode also
+#   reports instead of deleting. Falsifier: a default-discovered primary clone
+#   with one available clean pool copy removes that copy instead of recording a
+#   report-only terminal verdict.
+# - `bin/fm-next-cache-sweep.sh: command preflight -> command -v treehouse and
+#   python3`. Checked: absence exits 2, while every later invocation separately
+#   checks the command's status. Falsifier: a treehouse shim is found, emits valid
+#   `available` JSON, then exits 1, yet its row reaches candidate planning.
+# - `bin/fm-next-cache-sweep.sh: sweep_task_record_state_dirs ->
+#   sweep_resolve_directory "$STATE"`. Checked: physical resolution requires a
+#   searchable directory and failure propagates through the checked loader to
+#   `sweep_die`. Falsifier: `$STATE` is a dangling symlink and the sweep proceeds
+#   with an empty primary task-record set.
+# - `bin/fm-next-cache-sweep.sh: sweep_task_record_state_dirs ->
+#   sweep_read_text_file "$DATA/secondmates.md"`. Checked: the reader requires a
+#   regular non-symlink, stages a complete byte-for-byte read, rejects NUL, and
+#   propagates failure globally; the absent, unreadable, and NUL tests exercise
+#   those branches. Falsifier: the registry yields one complete local record and
+#   then an I/O error, but that partial prefix is accepted as the full registry.
+# - `bin/fm-next-cache-sweep.sh: sweep_task_record_state_dirs -> registry line
+#   loop and secondmate_registry_parse_line`. Checked: every registry record is
+#   defined by the shared parser's `- ` prefix; such a line must parse, local
+#   homes must be absolute and physically resolvable, and remote records are
+#   excluded by their explicit placement flag because they cannot own this host's
+#   pool. Falsifier: a syntactically valid local record with `home: ../mate` is
+#   treated as an absent home and contributes no task records.
+# - `bin/fm-next-cache-sweep.sh: sweep_load_task_worktrees -> state directory
+#   predicates and sweep_task_meta_files`. Checked: `-d`, `-r`, and `-x` precede
+#   a Python `os.scandir` whose exceptions and unsafe names are nonzero, and every
+#   nonzero status aborts the global loader. Falsifier: a state directory lists
+#   one `.meta` entry, then enumeration fails on another entry, but the first-only
+#   list is accepted as complete.
+# - `bin/fm-next-cache-sweep.sh: sweep_load_task_worktrees ->
+#   sweep_read_text_file "$meta" and metadata field loop`. Checked: the same
+#   complete reader rejects NUL, and one shell pass rejects duplicate, missing,
+#   non-absolute, or invalid-placement fields before appending a worktree. This
+#   replaced unchecked `sed` substitutions. Falsifier: metadata contains two
+#   `worktree=` fields, the second naming the candidate, and last-value parsing
+#   silently omits or replaces that owner.
+# - `bin/fm-next-cache-sweep.sh: sweep_path_identity -> cd, uname, and stat -L`.
+#   Checked: `cd && pwd -P` resolves the referent, `stat -L` follows a final
+#   symlink on both probed platforms, and empty or non-numeric device/inode output
+#   is rejected; identity-failure and symlink tests exercise the boundary.
+#   Falsifier: a final symlink to a recorded worktree is compared by the link's
+#   own inode, or a broken final symlink is accepted as a distinct candidate.
+# - `bin/fm-next-cache-sweep.sh: sweep_task_owns -> recorded paths and identities`.
+#   Checked: shell equality catches the exact spelling and resolved device/inode
+#   equality catches symlinked prefixes and case aliases. Falsifier: metadata
+#   names `/alias/pool/1` while the pool names `/real/pool/1`, both resolve to the
+#   same directory, and the candidate is classified unowned.
+#
+# Project discovery, pool, and candidate inputs:
+# - `bin/fm-next-cache-sweep.sh: sweep_project_directories -> os.scandir and
+#   entry.is_dir`. Checked: Python stages the complete immediate directory set,
+#   rejects unsafe paths, and turns enumeration or entry-type exceptions into a
+#   checked nonzero status; the unreadable-Git discovery test then preserves each
+#   announced project for project-scoped refusal. Falsifier: `entry.is_dir()`
+#   raises for one project while another is readable, and only the readable one
+#   reaches the target list and clean summary.
+# - `bin/fm-next-cache-sweep.sh: sweep_project -> sweep_resolve_directory and Git
+#   project queries`. Checked: physical entry and `git rev-parse --show-toplevel`
+#   must succeed and the physical top level must equal the argument; resolved
+#   `--absolute-git-dir` and absolute `--git-common-dir` must also be identical.
+#   Converted wrong verdict: root equality had proven a worktree root, not the
+#   primary clone. Falsifier: an explicit linked-worktree root passes top-level
+#   equality, then a pool row naming the primary clone passes the distinct-project
+#   comparison and is reported as a pool candidate.
+# - `bin/fm-next-cache-sweep.sh: sweep_pool_entries -> mktemp, treehouse status
+#   --json, staged-file read, JSON decode, and temp removal`. Checked: treehouse's
+#   status is captured before parsing, the file is decoded strictly as UTF-8 JSON,
+#   and staging, parse, top-level-shape, or cleanup failure returns nonzero before
+#   a plan exists. Falsifier: treehouse writes a complete first row and exits 1
+#   before its second row, but the first row is planned as a complete pool.
+# - `bin/fm-next-cache-sweep.sh: sweep_pool_entries -> JSON object decoding`.
+#   Checked: an object-pairs hook now rejects every repeated key before a decoded
+#   object or candidate row exists. Converted wrong verdict: syntactically decoded
+#   JSON had not guaranteed unambiguous lease evidence. Falsifier: one entry
+#   contains `"status":"in-use"` followed by `"status":"available"`, and
+#   last-value decoding produces a false unowned verdict.
+# - `bin/fm-next-cache-sweep.sh: sweep_pool_entries -> status and path fields`.
+#   Checked: Python requires both fields to be nonempty strings, the path to be
+#   absolute, and rejects NUL, tab, CR, and LF before emitting tab-delimited rows;
+#   malformed-field and NUL tests exercise the boundary. Falsifier: JSON status
+#   `avail\u0000able` crosses command substitution as `available` and reaches the
+#   exact-status check.
+# - `bin/fm-next-cache-sweep.sh: sweep_project_plan -> pool directory predicate,
+#   sweep_path_identity, and duplicate identity scan`. Checked: `-d` is required,
+#   physical device/inode identity is mandatory, and repeated identity produces
+#   an undetermined assessment. The complete pool listing is counted before any
+#   assessment begins. Falsifier: two different pool strings resolve to the same
+#   inode and are each applied, or a nonexistent first path prevents a valid later
+#   path from receiving a terminal verdict.
+# - `bin/fm-next-cache-sweep.sh: sweep_pool_worktree_provenance -> candidate root,
+#   project worktree registry, and project-clone exclusion`. Checked: candidate
+#   `--show-toplevel` must physically equal the candidate, the candidate identity
+#   must appear exactly once in `git worktree list --porcelain -z`, and it must
+#   differ from the supplied project identity. Wrong evidence chain: the supplied
+#   identity was previously proven only to be a root; it now passes the independent
+#   primary-clone proof above first. Falsifier: the pool names a child of a live
+#   registered worktree and Git reachability is mistaken for root identity, or a
+#   linked project argument makes the actual primary clone look like a distinct
+#   registered candidate.
+# - `bin/fm-next-cache-sweep.sh: sweep_unowned_reason -> pool status`. Checked:
+#   only byte-exact `available` proceeds, `in-use` records ownership, and every
+#   other value records undetermined. Falsifier: `available ` or `AVAILABLE`
+#   reaches clean-tree inspection as if it were byte-exact `available`.
+# - `bin/fm-next-cache-sweep.sh: sweep_unowned_reason -> git status --porcelain
+#   and git stash list`. Checked: each command substitution is status-checked,
+#   nonempty status or stash output records ownership, and failure records
+#   undetermined. Falsifier: `git status` prints an empty-looking result then exits
+#   1, or `git stash list` prints a stash then exits 1, and the copy is classified
+#   free from the captured text alone.
+# - `bin/fm-next-cache-sweep.sh: sweep_project_plan -> fm_next_cache_inspect and
+#   FM_NEXT_CACHE_* outputs`. Checked: the inspection status is checked before
+#   size and plan values are consumed, so failed discovery, eligibility, or
+#   measurement produces an undetermined assessment. Every candidate is assessed
+#   before project refusal is applied. Falsifier: `find` reports one `.next` then
+#   exits 1 and that partial measurement becomes a free row, or the failure stops
+#   a later announced pool path from being assessed.
+#
+# Shared build-output discovery and reporting inputs:
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_size_kb -> du -sk`. Checked: only a
+#   zero-status command with leading decimal digits followed by a separator is
+#   emitted; failure and malformed output are nonzero, as the size-failure test
+#   observes. Falsifier: `du` prints `0\t/path` then exits 1 and the directory is
+#   reported as measured empty.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_parent_is_next_app -> next.config.*
+#   predicates and Python package.json decoding`. Checked: a regular config is
+#   positive; valid object JSON is positive only when `next` is a key in a
+#   recognized dependency table only after every present recognized table is
+#   validated; no recognized key is negative; and unreadable, undecodable,
+#   duplicate-key, non-object, non-standard-constant, or malformed
+#   dependency-table JSON is undetermined. Falsifier: an early table names
+#   `next` while a later table is malformed, or `NaN` is accepted as JSON.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_is_build_output -> path existence,
+#   directory and symlink predicates, physical resolution, containment, git
+#   check-ignore, and app-root result`. Checked: only a real nonsymlink directory
+#   physically below the supplied root with check-ignore status 0 and app status
+#   0 qualifies; proven negatives return 1 and failures return 2. Falsifier: an
+#   ignored `.next` symlink points outside the worktree, or `git check-ignore`
+#   exits 128, and the candidate still returns the qualifying status 0.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_inspect -> worktree cd and git
+#   rev-parse --git-dir`. Checked: entry and Git failure set a named inspection
+#   error and return nonzero; `--git-dir` is needed here only to prove a repository
+#   is reachable because the sweep separately proves candidate-root provenance
+#   and teardown supplies its task worktree. Falsifier: a caller passes a repository
+#   child directory, `--git-dir` succeeds there, and that answer alone qualifies
+#   the child's build output.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_inspect -> mktemp, find -print0,
+#   NUL-delimited read, and temp removal`. Checked: the complete `find` status is
+#   captured before parsing, documented `-print0` records are path-validated, and
+#   any staging, walk, eligibility, measurement, or cleanup failure clears the
+#   accumulated plan and returns nonzero. Falsifier: `find` emits one complete NUL
+#   record then exits 1, yet that partial plan remains usable by the report.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_report -> plan rows and
+#   fm_next_cache_human_kb`. Checked: only inspect-generated numeric size/path
+#   rows reach formatting, and repeated inspection or numeric validation failure
+#   returns nonzero to the sweep. Falsifier: an internally corrupted plan row
+#   contains `bogus\t/path` and still prints success or contributes bytes.
+#
+# Outcome and summary inputs:
+# - `bin/fm-next-cache-sweep.sh: sweep_apply_project_plan -> report status,
+#   target mode, and FM_NEXT_CACHE_TOTAL_KB`. Checked: every target mode calls
+#   only `fm_next_cache_report`; default-discovered owned copies preserve their
+#   owned verdict, while free and explicit candidates get report-only verdicts.
+#   Falsifier: any target mode removes a planned directory, or reported bytes are
+#   summarized as reclaimed.
+# - `bin/fm-next-cache-sweep.sh: sweep_project_plan, sweep_project, project loop,
+#   and final summary -> announced candidates and final verdicts`. Checked: project
+#   plans remain atomic, the complete pool list announces indexed candidates
+#   before assessment, and one ledger records each terminal outcome. Per-project
+#   reconciliation proves each index occurs once; run reconciliation gates every
+#   clean summary. Falsifier: a three-row pool has an invalid first row and valid
+#   later rows, but either later index has no verdict, or a discarded row still
+#   increments the clean inspected count outside the ledger.

+# The leak this pins: a pooled task copy returns to the pool still holding its
+# Next.js build output. `treehouse return` resets tracked content and leaves
+# gitignored output alone, so nothing ever removes it and it accumulates copy by
+# copy until the volume fills. Measured 2026-08-18: 15 GB in one idle Artemis
+# copy on a volume with 11 GB free.
+#
+# bin/fm-next-cache-sweep.sh reports copies already sitting idle in the pool
+# using bin/fm-next-cache-lib.sh's discovery rule. Teardown and the sweep both
+# preserve build output because neither has a durable ownership fence.
+#
+# The cases that matter most are the refusals. A live dev server rewrites the
+# output the moment it is deleted, and deleting mid-build is worse than leaving
+# it alone, so every ownership proof gets its own case asserting the directory
+# SURVIVES.

+Use `bin/fm-fork-status.sh` for the local answer and add `--refresh` only when live remote and upstream review evidence is needed.
 After no-mistakes, use the post-pipeline candidate command in [`docs/fork-main.md`](../../../docs/fork-main.md); a bare invocation reads the fork remote rather than proving candidate `HEAD`.
 Its own errors, signals, and exit status are the machine verdict, and [`docs/fork-main.md`](../../../docs/fork-main.md) states how it classifies raw `git cherry` facts and what makes it unhealthy.

 `superseded` is immediate removal debt and must be empty after an upstream integration.
 
 The upstream review is a pull request or an issue, and the class does not depend on which.
+The fork's contribution order is to state the problem in an issue, discuss it, and open a pull request only after the problem is confirmed.
 Stating the problem as an issue and waiting for it to be confirmed is a real upstream route, so a divergence raised that way is `pending` exactly as one carrying a pull request is.
 The accepted forms are exactly two, `https://github.com/<owner>/<repo>/pull/<number>` and `https://github.com/<owner>/<repo>/issues/<number>`, and nothing else is treated as a route.
 An absent or malformed route is refused for every class but `private`, which is the check that stops a divergence being registered with no upstream story at all.
 
+Classification and validation remain separate.
+The ordinary no-mistakes upstream registration still opens a pull request in its `pr` step, so supporting validation and local adoption while upstream review remains issue-only requires its own change.
+
 `private` is not the place to park work that is merely unraised.
 It records a decision never to propose, so classifying an intended-but-unraised divergence as private would assert an intent the fork does not hold, and the manifest is later read as though it were true.

Subject: [PATCH 27/39] feat(bin): report Next.js build output in pooled
 worktrees (#23)

* feat(bin): report reclaimable Next.js build output in pooled worktrees

Pooled task copies accumulate Next.js build output that nothing removes.
`treehouse return` resets tracked content and leaves gitignored output where
it is, so a returned copy keeps it. On 2026-08-06 that contributed to a home
where every Bash call failed with ENOSPC for several minutes - nothing ran at
all, including df and du, so the problem could not even be measured - and a
coverage run was aborted mid-verification.

bin/fm-next-cache-sweep.sh inspects pooled copies and reports which hold
regenerable build output and how much. It deletes nothing.

Deletion is absent by design, not postponed, and both paths were removed for
proven reasons:

- The sweep cannot prove it owns a pooled copy. Holding a Treehouse lease
  across validation and deletion was the proposed remedy; either acquisition
  mutates the copy it hands out, or nobody has shown a lease covers the whole
  validation-through-deletion window. The proof does not exist today.
- Teardown-side reclamation is structurally unprovable under Treehouse's
  process-bound hold: ownership exists while a shell has its cwd in the
  worktree, and quietness is proven only when no such process remains. Both
  are read off the same observable, so no ordering makes both true at once,
  and exempting the holding shell would exempt a shell that can start a build.

Reclamation therefore depends on a task-lifetime durable lease, which would
make ownership independent of worktree processes. Until then this is
report-only, which is a boundary rather than a verdict about Treehouse.

What the report still buys, against the incident above: it names where the
gigabytes are without touching them, which is what was missing when the
problem could not be measured.

Every ownership input must be proven readable and complete before a copy is
even reported as assessable; anything unreadable, absent, malformed or
indeterminable is recorded as an unassessed verdict rather than skipped. The
header carries an input inventory in which each verdict states what was
checked and what would falsify it, and a falsifier rule governing how those
verdicts are written.

Fork divergence: it assumes a pooled-worktree layout and Next.js projects.

* no-mistakes(review): Report all cache states and accept absent registries

* no-mistakes(review): Preserve valid cache reports beside malformed entries

* no-mistakes(document): Document report-only Next.js cache inspection

* no-mistakes(document): Explain intentional cache-script index omission

* no-mistakes(review): Fix cache sweep completeness and integrity coverage

* no-mistakes(document): Correct cache-sweep documentation contracts

+# gives operators a useful view of accumulated, regenerable disk usage.
+#
+# Sourced by bin/fm-next-cache-sweep.sh, which reports build output and ownership
+# state for every copy announced by a project's pool. The discovery rule is
+# stated here once.
+#
+# WHAT IS REPORTED. Exactly directories named .next that pass BOTH proofs:
+#   1. git ignores the directory in the repo that contains it
+#      (`git check-ignore`). Tracked content can never match, so no source, no
+#      git data, and no committed fixture is reachable by this rule.
+#   2. its parent is a Next.js app root: a next.config.{js,cjs,mjs,ts,cts,mts}
+#      sits beside it, or the parent's valid package.json names `next` in a
+#      recognized dependency table. This is what makes the claim "regenerable
+#      build output" true rather than assumed - a gitignored directory that
+#      merely happens to be called .next is left alone.
+# Nothing is removed. node_modules, source, and git data are out of reporting
+# scope by construction, not by exclusion list: the walk prunes node_modules
+# and .git outright, and neither could pass proof 2 anyway.
+#
+# OTHER CACHES ARE DELIBERATELY OUT OF SCOPE. A project's gitignored `.tmp`
+# scratch root can hold audit output, coverage JSON, browser recordings, and
+# review artifacts that do not regenerate from source, while `dist` can be
+# tracked content. A generic cache-like name does not prove regenerability;
+# extend this rule only when a specific directory has that proof.
+#
+# Next.js documents .next as the build output directory (`distDir` defaults to
+# '.next') and clears it itself on every production build (`cleanDistDir`
+# defaults to true, preserving only .next/cache). That establishes the output as
+# regenerable without granting this code authority to remove it.
+# A project that sets a custom `distDir` is deliberately NOT discovered: reading
+# a build config to decide what to report would make eligibility depend on
+# untrusted project code. Such a project remains unreported, which is the safe
+# direction to be wrong in.
+#
+# The walk prunes node_modules and .git, and stops descending at each .next it
+# finds, so a nested .next under .next/standalone is reported with its parent
+# rather than counted twice.
+#
+# This library only inspects and reports. The sweep combines its measurements
+# with pool state, task records, and tree state to classify each copy. Sourcing
+# this file grants no authority to remove anything.

+# Report Next.js build output and ownership state in pooled worktrees.
+#
+# This feature is report-only. Teardown-side reclamation was removed as
+# unprovable, not postponed: under Treehouse's process-bound hold, ownership
+# exists while a shell has its cwd in the worktree, but quietness is proven only
+# when no such process remains. Reordering cannot make both proofs true at once,
+# and exempting the holding shell would exempt a shell that can start a build.
+# Every returned copy, including forced-cleanup descendants, therefore retains
+# its build output. This sweep inventories that output and removes nothing.
+#
+# Sweep-side deletion is also absent because no lease has been shown to cover the
+# whole validation-through-deletion window. A sufficient lease would have to make
+# ownership independent of worktree processes and remain valid through removal;
+# this command claims no such lease and has no deletion capability.
+#
+# This report-only boundary is not a verdict about Treehouse acquisition
+# behavior; this command never acquires a copy.
+# It is a command a human or firstmate runs; there is deliberately no daemon,
+# watcher, schedule, or disk-pressure trigger behind it.
+# This fork-carried tool is deliberately absent from docs/scripts.md because an
+# entry in that frequently changed upstream index would create a standing merge
+# conflict. Its own header and AGENTS.md keep it discoverable.
+#
+# Usage: fm-next-cache-sweep.sh [--dry-run] [<project-dir>...]
+#   --dry-run   retained as a report-only compatibility spelling.
+#   <project-dir>...  inspect and report these project clones' pools.
+#
+# WHAT IT INSPECTS. Only pooled task copies, and only the Next.js build output
+# inside them - bin/fm-next-cache-lib.sh's header owns that discovery rule. The
+# project clone itself is never inspected as a pool copy; only records announced
+# by its pool are candidates.
+#
+# OWNERSHIP CLASSIFICATION USES FOUR CHECKS:
+#   1. treehouse reports its state. The documented `available`, `in-use`,
+#      `dirty`, and `leased` states are printed by name. An unrecognized state
+#      produces an undetermined verdict instead of an eligibility claim.
+#   2. No task record names it. This home's state/*.meta plus every registered
+#      secondmate home's, so a copy owned by a task in another home is skipped
+#      even if its lease was somehow released.
+#   3. The tree is clean. Uncommitted work is unlanded work.
+#   4. There are no stashes. A stash is unlanded work that a clean tree does not
+#      show, and nobody is watching an idle copy to notice it disappear.
+# Checks 3 and 4 read git and change nothing. A proven owner is measured and
+# listed as `skipped-as-owned` during default discovery; for an explicitly named
+# project, its directories are reported with the ownership reason. An absent
+# secondmate registry means no registered secondmates. An unreadable or malformed
+# present registry refuses the sweep, and an unreadable pool refuses its project.
+# Candidate uncertainty produces one undetermined line without suppressing the
+# other candidates.
+#
+# It reports a verdict for every announced pool record, including the measured
+# total when inspection succeeds, and says plainly when it found nothing. There
+# is no flag, environment variable, or target origin that grants this command
+# deletion authority.
+#
+# Exit status is 0 when the inspection completed, 1 when reporting is partial or
+# a project's pool lookup failed (already reported), 2 on a usage or environment
+# error.
+#
+# FALSIFIER RULE - read this before adding or editing any verdict below.
+#
+# A falsifier must name the concrete case that would DEFEAT the check.
+# It must never name the category the check already rejects.
+#
+# A falsifier that restates the check is vacuous: it passes exactly when the
+# check passes, so it can never reveal that the check is too narrow. The test
+# to apply is not "what does this check reject?" but "what would SATISFY this
+# check and still violate the property the verdict claims to establish?"
+#
+# For example, a linked worktree is a root but is not the primary clone, so a
+# falsifier for the primary-clone check must name that case rather than merely
+# naming a non-root argument. Keep these distinctions explicit:
+#   `git rev-parse --git-dir` answering        proves a repo is REACHABLE, not that the path is its root
+#   `--show-toplevel` equalling the path       proves the path is A worktree root, not the PRIMARY one
+#   `--absolute-git-dir` = `--git-common-dir`  proves the primary worktree, which is the property needed
+#
+# A quick way to find suspect entries: any falsifier phrased as a negation or a
+# category of what the check tests - "any non-X", "a missing X", "an unreadable
+# X" - is probably restating the check rather than defeating it. Re-derive those
+# first.
+#
+# INPUT COMPLETENESS INVENTORY
+#
+# The contract for every item below is that an unreadable, malformed, ambiguous,
+# or incomplete ownership input cannot produce a false determinate answer.
+# A global input refuses the sweep, a project input may refuse that project
+# before candidates are known, and a copy input receives an undetermined verdict
+# while every other announced copy is still reported.
+#
+# Each source site is identified by file, function, and the exact statement or
+# command that reads it rather than by a numeric line that this inventory itself
+# would immediately invalidate. The inventory was built by tracing every
+# external command and status, command substitution, filesystem predicate and
+# directory entry, file parser, environment or CLI value, Python-to-shell
+# boundary, and summary selector. That input-oriented trace includes implicit
+# omission paths that a syntax search for `continue` cannot find.
+#
+# Every verdict below carries both the observation it rests on and a concrete
+# falsifier: a case that could satisfy the named check while still violating the
+# property that check is meant to establish. Restating the check as "a non-X"
+# is not evidence that the check establishes the broader property.
+#
+# Sweep entry and global ownership inputs:
+# - `bin/fm-next-cache-sweep.sh: startup -> BASH_SOURCE, FM_* overrides, cd,
+#   readable library predicates, and source`. Checked: every failed directory
+#   command substitution is tested, both library paths must pass `-r`, and a
+#   nonzero source status exits before target construction. Falsifier: an
+#   override whose parent cannot be searched, or a readable library whose source
+#   command returns nonzero, reaches target construction as a complete report.
+# - `bin/fm-next-cache-sweep.sh: argument loops -> "$@"`. Checked: the option
+#   case accepts `--dry-run`, `-h`, and `--help`, honors `--`, rejects every other
+#   dash-prefixed value with exit 2, and retains non-options verbatim. Falsifier:
+#   `--unknown` is retained as a project, or `-- /path` loses the literal project
+#   path before validation.
+# - `bin/fm-next-cache-sweep.sh: target construction -> PROJECT_ARGS,
+#   sweep_project_directories, and TARGETS`. Checked: each target record carries
+#   `explicit-report` or `pool-report`, and any missing or unknown mode also
+#   reports instead of deleting. Falsifier: a default-discovered primary clone
+#   with one available clean pool copy removes that copy instead of recording a
+#   report-only terminal verdict.
+# - `bin/fm-next-cache-sweep.sh: command preflight -> command -v treehouse and
+#   python3`. Checked: absence exits 2, while every later invocation separately
+#   checks the command's status. Falsifier: a treehouse shim is found, emits valid
+#   `available` JSON, then exits 1, yet its row reaches candidate planning.
+# - `bin/fm-next-cache-sweep.sh: sweep_task_record_state_dirs ->
+#   sweep_resolve_directory "$STATE"`. Checked: physical resolution requires a
+#   searchable directory and failure propagates through the checked loader to
+#   `sweep_die`. Falsifier: `$STATE` is a dangling symlink and the sweep proceeds
+#   with an empty primary task-record set.
+# - `bin/fm-next-cache-sweep.sh: sweep_task_record_state_dirs ->
+#   sweep_read_text_file "$DATA/secondmates.md"`. Checked: an lstat result
+#   distinguishes confirmed absence from lookup failure, then the reader requires
+#   a regular non-symlink, stages a complete byte-for-byte read, rejects NUL, and
+#   propagates read failure for a present registry; confirmed absence is the
+#   documented empty-registry default. Falsifier: a present registry yields one
+#   complete local record and then an I/O error, but that partial prefix is
+#   accepted as the full registry.
+# - `bin/fm-next-cache-sweep.sh: sweep_task_record_state_dirs -> registry line
+#   loop and secondmate_registry_parse_line`. Checked: every registry record is
+#   defined by the shared parser's `- ` prefix; such a line must parse, local
+#   homes must be absolute and physically resolvable, and remote records are
+#   excluded by their explicit placement flag because they cannot own this host's
+#   pool. Falsifier: a syntactically valid local record with `home: ../mate` is
+#   treated as an absent home and contributes no task records.
+# - `bin/fm-next-cache-sweep.sh: sweep_load_task_worktrees -> state directory
+#   predicates and sweep_task_meta_files`. Checked: `-d`, `-r`, and `-x` precede
+#   a Python `os.scandir` whose exceptions and unsafe names are nonzero, and every
+#   nonzero status aborts the global loader. Falsifier: a state directory lists
+#   one `.meta` entry, then enumeration fails on another entry, but the first-only
+#   list is accepted as complete.
+# - `bin/fm-next-cache-sweep.sh: sweep_load_task_worktrees ->
+#   sweep_read_text_file "$meta" and metadata field loop`. Checked: the same
+#   complete reader rejects NUL, and one shell pass rejects duplicate, missing,
+#   non-absolute, or invalid-placement fields before appending a worktree.
+#   Falsifier: metadata contains two `worktree=` fields, the second naming the
+#   candidate, and last-value parsing silently omits or replaces that owner.
+# - `bin/fm-next-cache-sweep.sh: sweep_path_identity -> cd, uname, and stat -L`.
+#   Checked: `cd && pwd -P` resolves the referent, `stat -L` follows a final
+#   symlink on both probed platforms, and empty or non-numeric device/inode output
+#   is rejected; identity-failure and symlink tests exercise the boundary.
+#   Falsifier: a final symlink to a recorded worktree is compared by the link's
+#   own inode, or a broken final symlink is accepted as a distinct candidate.
+# - `bin/fm-next-cache-sweep.sh: sweep_task_owns -> recorded paths and identities`.
+#   Checked: shell equality catches the exact spelling and resolved device/inode
+#   equality catches symlinked prefixes and case aliases. Falsifier: metadata
+#   names `/alias/pool/1` while the pool names `/real/pool/1`, both resolve to the
+#   same directory, and the candidate is classified unowned.
+#
+# Project discovery, pool, and candidate inputs:
+# - `bin/fm-next-cache-sweep.sh: sweep_project_directories -> os.scandir and
+#   entry.is_dir`. Checked: Python stages the complete immediate directory set,
+#   rejects unsafe paths, and turns enumeration or entry-type exceptions into a
+#   checked nonzero status; the unreadable-Git discovery test then preserves each
+#   announced project for project-scoped refusal. Falsifier: `entry.is_dir()`
+#   raises for one project while another is readable, and only the readable one
+#   reaches the target list and clean summary.
+# - `bin/fm-next-cache-sweep.sh: sweep_project -> sweep_resolve_directory and Git
+#   project queries`. Checked: physical entry and `git rev-parse --show-toplevel`
+#   must succeed and the physical top level must equal the argument; resolved
+#   `--absolute-git-dir` and absolute `--git-common-dir` must also be identical.
+#   Root equality alone proves a worktree root, not the primary clone.
+#   Falsifier: an explicit linked-worktree root passes top-level equality, then a
+#   pool row naming the primary clone passes the distinct-project comparison and
+#   is reported as a pool candidate.
+# - `bin/fm-next-cache-sweep.sh: sweep_pool_entries -> mktemp, treehouse status
+#   --json, staged-file read, JSON decode, and temp removal`. Checked: treehouse's
+#   status is captured before parsing, the file is decoded strictly as UTF-8 JSON,
+#   and staging, parse, top-level-shape, or cleanup failure returns nonzero before
+#   a plan exists. Falsifier: treehouse writes a complete first row and exits 1
+#   before its second row, but the first row is planned as a complete pool.
+# - `bin/fm-next-cache-sweep.sh: sweep_pool_entries -> JSON object decoding`.
+#   Checked: an object-pairs hook rejects every repeated key and the constant
+#   parser rejects NaN and infinities before a candidate row exists. Syntactic
+#   JSON validity alone does not guarantee unambiguous lease evidence.
+#   Falsifier: one entry contains `"status":"in-use"` followed by
+#   `"status":"available"`, and last-value decoding produces a false unowned
+#   verdict.
+# - `bin/fm-next-cache-sweep.sh: sweep_pool_entries -> status and path fields`.
+#   Checked: every non-object record, unusable status, unusable path, control
+#   character, or non-absolute path becomes a specific fault row naming its pool
+#   entry while valid siblings remain assessable. Falsifier: JSON status
+#   `avail\u0000able` crosses command substitution as `available`, or a later
+#   unusable record suppresses an earlier valid copy's report verdict.
+# - `bin/fm-next-cache-sweep.sh: sweep_project_plan -> pool directory predicate,
+#   row kind, sweep_path_identity, and duplicate identity scan`. Checked: fault
+#   rows become undetermined assessments, usable rows require `-d` and a physical
+#   device/inode identity, and repeated identity produces an undetermined
+#   assessment. The complete pool listing is counted before any assessment
+#   begins. Falsifier: two different pool strings resolve to the same inode and
+#   are each applied, or one fault row prevents a valid sibling from receiving a
+#   terminal verdict.
+# - `bin/fm-next-cache-sweep.sh: sweep_pool_worktree_provenance -> candidate root,
+#   project worktree registry, and project-clone exclusion`. Checked: candidate
+#   `--show-toplevel` must physically equal the candidate, the candidate identity
+#   must appear exactly once in `git worktree list --porcelain -z`, and it must
+#   differ from the supplied project identity. The supplied identity passes the
+#   independent primary-clone proof above before this comparison.
+#   Falsifier: the pool names a child of a live registered worktree and Git
+#   reachability is mistaken for root identity, or a linked project argument
+#   makes the actual primary clone look like a distinct registered candidate.
+# - `bin/fm-next-cache-sweep.sh: sweep_unowned_reason -> pool status`. Checked:
+#   byte-exact `available`, `in-use`, `dirty`, and `leased` are named,
+#   non-available documented states record ownership, and every other value
+#   records undetermined. Falsifier: `available ` or `AVAILABLE` reaches
+#   clean-tree inspection as if it were byte-exact `available`.
+# - `bin/fm-next-cache-sweep.sh: sweep_unowned_reason -> git status --porcelain
+#   and git stash list`. Checked: each command substitution is status-checked,
+#   nonempty status or stash output records ownership, and failure records
+#   undetermined. Falsifier: `git status` prints an empty-looking result then exits
+#   1, or `git stash list` prints a stash then exits 1, and the copy is classified
+#   free from the captured text alone.
+# - `bin/fm-next-cache-sweep.sh: sweep_project_plan -> fm_next_cache_inspect and
+#   FM_NEXT_CACHE_* outputs`. Checked: the inspection status is checked before
+#   size and plan values are consumed, so failed discovery, eligibility, or
+#   measurement produces an undetermined assessment. Every candidate is assessed
+#   and applied independently. Falsifier: `find` reports one `.next` then exits 1
+#   and that partial measurement becomes a free row, or the failure stops a later
+#   announced pool path from being reported.
+#
+# Shared build-output discovery and reporting inputs:
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_size_kb -> du -sk`. Checked: only a
+#   zero-status command with leading decimal digits followed by a separator is
+#   emitted; failure and malformed output are nonzero, as the size-failure test
+#   observes. Falsifier: `du` prints `0\t/path` then exits 1 and the directory is
+#   reported as measured empty.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_parent_is_next_app -> next.config.*
+#   predicates and Python package.json decoding`. Checked: a regular config is
+#   positive; valid object JSON is positive only when `next` is a key in a
+#   recognized dependency table only after every present recognized table is
+#   validated; no recognized key is negative; and unreadable, undecodable,
+#   duplicate-key, non-object, non-standard-constant, or malformed
+#   dependency-table JSON is undetermined. Falsifier: an early table names
+#   `next` while a later table is malformed, or `NaN` is accepted as JSON.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_is_build_output -> path existence,
+#   directory and symlink predicates, physical resolution, containment, git
+#   check-ignore, and app-root result`. Checked: only a real nonsymlink directory
+#   physically below the supplied root with check-ignore status 0 and app status
+#   0 qualifies; proven negatives return 1 and failures return 2. Falsifier: an
+#   ignored `.next` symlink points outside the worktree, or `git check-ignore`
+#   exits 128, and the candidate still returns the qualifying status 0.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_inspect -> worktree cd and git
+#   rev-parse --git-dir`. Checked: entry and Git failure set a named inspection
+#   error and return nonzero; `--git-dir` is needed here only to prove a repository
+#   is reachable because the sweep separately proves candidate-root provenance.
+#   Falsifier: a caller passes a repository child directory, `--git-dir` succeeds
+#   there, and that answer alone qualifies the child's build output.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_inspect -> mktemp, find -print0,
+#   NUL-delimited read, and temp removal`. Checked: the complete `find` status is
+#   captured before parsing, documented `-print0` records are path-validated, and
+#   any staging, walk, eligibility, measurement, or cleanup failure clears the
+#   accumulated plan and returns nonzero. Falsifier: `find` emits one complete NUL
+#   record then exits 1, yet that partial plan remains usable by the report.
+# - `bin/fm-next-cache-lib.sh: fm_next_cache_report -> plan rows and
+#   fm_next_cache_human_kb`. Checked: only inspect-generated numeric size/path
+#   rows reach formatting, and repeated inspection or numeric validation failure
+#   returns nonzero to the sweep. Falsifier: an internally corrupted plan row
+#   contains `bogus\t/path` and still prints success or contributes bytes.
+#
+# Outcome and summary inputs:
+# - `bin/fm-next-cache-sweep.sh: sweep_apply_project_plan -> report status,
+#   target mode, and FM_NEXT_CACHE_TOTAL_KB`. Checked: every target mode calls
+#   only `fm_next_cache_report`; default-discovered owned copies preserve their
+#   owned verdict, while free and explicit candidates get report-only verdicts.
+#   Falsifier: any target mode removes a planned directory, or reported bytes are
+#   summarized as reclaimed.
+# - `bin/fm-next-cache-sweep.sh: sweep_project_plan, sweep_project, project loop,
+#   and final summary -> announced candidates and final verdicts`. Checked: project
+#   plans preserve every independently reportable row, the complete pool list
+#   announces indexed candidates before assessment, and one ledger records each
+#   terminal outcome. Per-project reconciliation proves each index occurs once;
+#   run reconciliation gates every clean summary. Falsifier: a three-row pool has
+#   an invalid first row and valid later rows, but either later index has no
+#   report verdict, or a discarded row increments the clean inspected count.

+# and leaves gitignored output alone, while Firstmate does not remove that output
+# on return, so it can accumulate across pooled copies.
+#
+# bin/fm-next-cache-sweep.sh reports every copy announced by the pool using
+# bin/fm-next-cache-lib.sh's discovery rule. Teardown and the sweep both preserve
+# build output because neither has a durable ownership fence.
+#
+# Ownership classification never grants deletion authority. A live dev server
+# can rewrite the output during a report, so every ownership state gets its own
+# case asserting the directory survives.
+# The whole-tree manifest assertion's red state was confirmed by temporarily
+# appending one `x` byte to .next/static/chunk.js after the pre-sweep snapshot.

+A binding uses cross-origin mode by default; an optional concrete origin exists only for legacy pre-collapse records, and the command header owns the exact forms and key interpretation.
 The 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 source needs nothing here beyond an `answers` command and a binding.
 Feeding is independent of handling: it never acknowledges a result and never suppresses a wake, because recording the answer is transcription while acting on it is firstmate's judgement.
 An unbound source, an adapter with no `answers` command, and a failure on either side all leave the capture untouched and still announced.

 An `arming` entry stays in flight however old it is, because the owner foregrounds the arm for the whole watcher cycle.
 The shapes the ledger cannot settle are settled by identity instead: the claim records the same `pid-identity` file every other supervision lock records, before it publishes its `autoarm` role, so a recorded identity that no longer matches the pid holding the lock proves abandonment on its own even while the entry still reads `arming` or no ledger entry exists at all.
 That covers a claim whose process group was killed before it could record any outcome and whose pid the operating system later handed to an unrelated live process.

 `.github/workflows/ci.yml` derives the same `n` from `strategy.job-total` rather than a literal, so changing the shard count in either file without the other fails the lane loudly instead of leaving part of the required suite unrun.
 
 Assignment is longest-processing-time bin packing over per-script duration hints embedded in `bin/fm-test-run.sh`.
-The hints came from the `fm-test-timing-portable-serial-*` artifacts of green CI run [32491999845](https://github.com/kunchenguid/firstmate/actions/runs/32491999845) on 2026-08-21, where the lane ran 116 scripts in 2541548 ms of serial work.
+Most upstream hints came from the `fm-test-timing-portable-serial-*` artifacts of green CI run [32491999845](https://github.com/kunchenguid/firstmate/actions/runs/32491999845) on 2026-08-21, where the lane ran 116 scripts in 2541548 ms of serial work.
 `tests/fm-tool-update-check.test.sh` did not exist on that run, so its 12846 ms hint comes from the shard 3 artifact of run [32461816719](https://github.com/kunchenguid/firstmate/actions/runs/32461816719), which is the first run that measured it.
+The fork-only `tests/fm-fork-main.test.sh` retains its 35000 ms fork hint, `tests/fm-bootstrap-network-parallel.test.sh` carries an explicit 8000 ms hint from its later addition, and all remaining fork-only or later additions fall back to the default because no hint is recorded.
 A script with no hint gets the conservative `PORTABLE_SERIAL_DEFAULT_WEIGHT_MS` default.
 Hints only affect balance: the coverage guard keeps the partition complete and disjoint whatever they say, so a stale hint costs a slower shard rather than lost coverage.
 Balance is still worth keeping current, because enough unmeasured scripts let one shard carry more than twice another shard's real work and reach the job cap while another runner sits idle.

 `bin/fm-crew-state.sh <id>` is the cheap current-state read for an actionable heartbeat review: it attributes a no-mistakes run, active or terminal, only when it matches the crew's branch and current code identity, then keeps that run-step authoritative even if the pane has closed.
 The script header owns the exact run-head ancestry rules.
 During no-mistakes' `ci` monitor phase, it also reads the ci step log tail because `axi status` reports both "still waiting on checks" and "checks green, waiting on merge" as `ci,running`.
-The most recent recognized ci log marker wins, so checks-green monitoring reports done while a later re-arm, failed-check, or issue marker returns the crew to working.
+The most recent whole-line CI marker is treated as an observation, and `forge_zero_check_verdict` in `bin/fm-crew-state.sh` owns the exact terminal-evidence rule before the active monitor reports done or no CI configured.
 Only when no matching run exists does it consult semantic busy state; exact busy reports working, exact idle permits fallback to a status-log event whose 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.

 Resume fleet supervision immediately after the decision lands.
 
 Judge validation by the current-code-matched run step through `bin/fm-crew-state.sh`, not by shell liveness or the last status event.
-Running, fixing, or CI states remain working; parked approval or fix-review states require the worker to follow the active gate help; passed or checks-passed is done; failed or cancelled is failed.
+Running or fixing states remain working, while a plain `ci,running` run step is inconclusive and must not override `bin/fm-crew-state.sh`'s current-state verdict; parked approval or fix-review states require the worker to follow the active gate help; passed or checks-passed is done; failed or cancelled is failed.
 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.
