Backend +# independent, and the only source that survives a restore that re-parents +# or relabels panes. +# 2. the backend's pane/shell pid, then the deepest descendant of it (the +# foreground process), read through /proc. Only tmux exposes a verified +# per-pane pid; herdr, zellij, cmux, and orca do not, so they fall through. +# 3. nothing - the caller may use its own pane-cwd hint, LABELLED as a hint. +# +# Every reader prints one tab-separated verdict record so no call site invents +# its own shape: +# <source>\t<pid>\t<cwd> +# with source one of: +# proc - authoritative, read from the named process +# unverified - a process was found but its task identity is incomplete +# unknown - no authoritative reading is available here (pid and cwd empty) +# +# On a host without procfs (macOS) step 1 is unavailable and step 2 falls back +# to `lsof -d cwd`; when neither works the verdict is `unknown` rather than a +# pane value silently promoted to evidence. +# +# docs/worker-isolation.md owns how this mechanism fits with the other three, +# and docs/verification/worker-isolation.md owns the per-provider evidence. +# +# This file is sourced by scripts and has no side effects on source. + +_FM_AGENT_CWD_LIB_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)" +.

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. +# +# 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) and `›` (codex) are a +# genuine empty agent composer either way, bordered or bare. +# +# 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. +# +# Each adapter still owns its own CAPTURE and structural row-finding, because +# those use genuinely different primitives (tmux's cursor-row read or Herdr's +# ANSI visible-row read). 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.

their script headers own the exact functions, arguments, and record shapes, and this document owns how they fit together and why the boundaries sit where they do. +[`docs/verification/worker-isolation.md`](verification/worker-isolation.md) owns the dated empirical evidence. + +## What it guarantees + +- A task child never resolves, acquires, or acts against the operational home that launched it, and a secondmate resolves only its own home. +- "Where is this agent actually running?" is answered from the agent process itself, never from a session provider's pane field. +- A pooled worktree slot is never released while any other task still references it, including a paused or quarantined one. + +## Why it exists + +Three defects were observed live, not hypothesized. +Each one defeated a guard that looked sufficient until it was tested against real fleet behavior. + +**A worker inherited the primary's home (2026-07-24).** +An audit agent launched from a primary's pane inherited that primary's exported `FM_HOME`. +Every firstmate script it then ran resolved the primary's state directory, and running session start took the primary's own session-owner record. +The real primary was suspended and resumed, came back locked out of its own home, and stopped monitoring. +The lesson is that ownership cannot be inferred downstream from cwd, pane, or process tree; it has to be declared at launch. + +**The spawn-time isolation assertion did not survive a restore (2026-07-24).** +After a reboot the session provider restored every pane by resuming its recorded agent session, but resolved each working directory back to the repository the worktree was derived from. +All 17 isolated worktrees collapsed onto their origin, four of them into the firstmate primary checkout. +No writes occurred before they were retired, verified from pre-reboot mtimes. +The lesson is that an assertion made once at launch is not a property that holds afterwards; isolation has to be re-established from live evidence on every resume. + +**Recorded `worktree=` is not proof of ownership (2026-07-24, fired 2026-07-25).** +A census found ten pooled slots recorded by more than one task, up to six each. +The hazard then fired: tearing down one task released a lease that a still-live quarantined-paused task also recorded, and the pool reissued that exact slot to a new spawn. +No work was lost, because a task's work lives on its branch and because teardown had been run records-and-panes-only. +The lesson is that disposal has to be gated on live evidence about the slot, and that the records-and-panes-only policy which made the collision harmless should be the deterministic default rather than a manual choice. + +A fourth finding corrected the method used to investigate the others. +A pane listing reported a worker's cwd as the primary checkout while `/proc/<pid>/cwd` showed it correctly isolated, because the pane field had picked up a different process sharing the workspace. +A pane read is therefore a hint and never evidence. + +## The four mechanisms + +### Declared agent identity + +`bin/fm-worker-isolation-lib.sh` owns the launch-time declaration. +`bin/fm-spawn.sh` prepends it to every launch command, so the declaration is part of the command the provider runs rather than state the child has to look up. + +Two roles exist. +A `crewmate` covers every ship, scout, and audit child; it is never a primary anywhere, so it is launched with every operational-home variable cleared. +A `secondmate` is the primary of its own home and only there, so it keeps a concrete `FM_HOME` while every inheritable override is cleared. +A secondmate's own crewmates are launched by that home's own `bin/fm-spawn.sh` and get the crewmate treatment against the secondmate's home, which is what stops a secondmate's child from ever reaching the primary. + +The declaration is a refusal point, not a best effort: an unknown role, an empty id, or a non-absolute home fails rather than emitting a partial prefix, because a partial prefix is exactly the inheritance the mechanism exists to prevent. + +Three enforcement points consume the declaration. +`bin/fm-lock.sh` refuses acquisition before it resolves or creates a state directory, so a worker cannot even publish a probe file into a home it inherited, while read-only `status` stays available. +`bin/fm-primary-scope-lib.sh` reports a declared worker as non-primary whatever root and state it was handed, which keeps every tracked project-local startup and turn-end adapter inert for workers. +`bin/fm-spawn.sh` and `bin/fm-teardown.sh` refuse outright, because a worker acting on an inherited home would create or destroy direct reports the real primary never recorded. + +### The method of record for an agent's working directory + +`bin/fm-agent-cwd-lib.sh` owns the answer and its per-provider limits. +Resolution is most-authoritative-first: the root-most live process carrying the task's declaration marker, then the provider's pane process id descended to the running agent, then `unknown`. +It never falls back to a pane value, so a caller that wants a hint has to ask its provider for one and label it as a hint. + +The declaration marker matters here beyond home isolation: it is the provider-independent identity key, and it is the only source that survives a restore which re-parents or relabels panes. + +Per-provider process id availability: + +| Provider | Per-pane process id | Consequence | +|---|---|---| +| tmux | `#{pane_pid}`, a real shell pid | Process cwd is readable without the marker, but task isolation still requires complete worker identity. | +| herdr | none; the pane API exposes `foreground_cwd` only | Authoritative reading requires the declaration marker. | +| zellij | none exposed at all | Same. | +| cmux | none on the control socket | Same. | +| orca | none on the terminal endpoint | Same. | + +A provider with no process id is not a failure of the library. +It means a task that also lacks the declaration marker has only a hint, which is reported as `unknown` rather than promoted to evidence. + +A tmux target is resolved to its stable window id by exact enumeration before any pane is read. +`display-message` given a window name it cannot find silently answers for the *active client's* window instead, so a task whose window name was lost or auto-renamed would hand back firstmate's own pane, whose working directory is the primary checkout - a healthy worker reported as collapsed. +No exact match reports `unknown`, which is why a caller must never re-derive the pane pid from a name itself. + +A caller that asks about many tasks passes one process index built from a single `/proc` walk. +Asking per task instead re-walks every process for every task, and the resume sweep runs on the session-start critical path over a home that has held seventeen concurrent tasks. + +Reading another process's environment needs care that is easy to get wrong. +The mode bits on `/proc/<pid>/environ` are not sufficient permission, because the kernel additionally requires ptrace read access; a same-uid but privileged process passes a readability test and still fails at open. +The failing redirect has to be silenced with the group form, since redirections are applied left to right and a trailing `2>/dev/null` on the same command is set up only after the input redirect has already printed to stderr. +Getting this wrong turns unrelated host processes into stderr noise on a read-only sweep. + +### Pooled-slot ownership + +`bin/fm-slot-owner-lib.sh` owns the release-or-retain verdict. +Disposal is gated on positive evidence of a conflict in three independent forms, any one of which retains the lease: another task recorded in a discoverable home naming the same physical slot, an ownership stamp naming a different task or home, or a live/closed-endpoint occupancy proof finding a foreign, unidentified, or otherwise unproven process inside the slot. + +The stamp is written by `bin/fm-spawn.sh` into the worktree's private git directory, never into the working tree, so it can never dirty a status check or reach a commit. +Writing is refused for anything that is not a linked worktree, so a primary checkout can never be marked as a disposable slot. + +Two boundaries are deliberate. +Absence of evidence is not evidence: a slot with no stamp retains its lease, even without a conflicting reference, because current ownership cannot be proved safely. +The same fail-closed rule applies when a recorded worktree path is missing: teardown preserves the task record and lease because it cannot prove which slot, if any, remains held. +A secondmate home whose directory is already gone is the one carve-out, and it is decided on evidence rather than on the missing path: git keeps the worktree registration of a removed slot, so that registration is what proves a lease may still be held. +A home with no such registration never drew a pooled slot - a plain clone - and has nothing to return, so refusing it forever would only make it permanently unretirable. +`--force` does not waive the gate: it is the captain's authority to discard *this* task's work, never authority to release another task's slot. + +Retaining means the lease is retired rather than returned. +`bin/fm-teardown.sh` leaves the directory completely untouched - no branch delete, no hook-file removal, no pool return - and still completes the rest of the teardown, reporting the retained slot on its completion line. +A conflicting secondmate home or Orca worktree refuses outright instead, because silently skipping their removal would strand a registry entry or an Orca-owned worktree. + +Retention is not a one-way door. +A task that retains because another task's metadata still names the slot *and then completes its own teardown* gives up its own ownership stamp on the way out, so the holder left behind can release the slot normally once nothing else references it. +That clear is deliberately narrow in two directions. +A stamp naming a *different* task is always preserved, because it is the evidence that stops a stale task from disposing of a slot whose real occupant is merely paused or between processes, and destroying preserved work would be strictly worse than leaking a slot. +A caller that refuses outright preserves the stamp too, because a refused operation mutates nothing: its records all stay, ownership did not change, and stripping the evidence there would set up exactly that same destructive sequence once those records are reconciled away. +Each call site therefore states which of the two it is, so a new caller cannot silently inherit the wrong behaviour. +The live-occupant check stays a blocking condition and is never weakened to compensate. +The ownership stamp is required and must be one exact regular record. A missing, +malformed, or unreadable stamp retains the lease; no teardown may expose a slot +when current ownership cannot be proved. Ordinary spawn holds a task-bound +durable Treehouse lease from acquisition through teardown, so a worker exit +cannot return and reissue the stamped slot behind Firstmate's back. +When the endpoint is live, teardown inspects only that endpoint's foreground +process, cwd, and worker declaration. An unavailable exact endpoint proof retains +the durable lease; unrelated host processes are not occupancy evidence. +If authoritative cwd or process-identity capability is unavailable, the slot is retained. +Once a process is proven inside the slot, unreadable, partial, undeclared, or mixed-version identity is contested ownership rather than absence of an occupant. +When the endpoint is closed, teardown uses a complete same-user process census of +the slot to catch a reparented or undeclared process. An incomplete census +retains the lease; only a complete empty census permits disposal. +The live endpoint path is stable-proofed by checking the endpoint pid, process +start time, cwd, and declaration twice; PID reuse or any changed identity/cwd +observation retains the lease as unproven. + +The restore-time isolation sweep returns nonzero when any identity or cwd finding is actionable or unproven. Bootstrap reports those findings in read-only mode and refuses every later mutation until the sweep is clean. + +#### Interrupted returns and unresolved leases + +Two durable records exist so a crash can never hide the state of a pooled slot, and neither may become a one-way door. + +`slot_returning=1` in `state/<id>.meta` is written immediately before `treehouse return` and means the return started and its outcome is unknown. +Teardown refuses while it is set, because retrying a return whose first attempt may have partly succeeded is exactly how a slot gets reissued out from under a live holder. +It is cleared automatically whenever the return provably did *not* take effect - the slot is still a linked worktree carrying this task's own ownership stamp - so the ordinary failure stays retryable. +When that cannot be proved, teardown prints a `teardown: RECOVERY:` line naming the meta file and the slot: confirm with `treehouse list` whether the slot is still leased to the task, then delete the `slot_returning=1` line to retry, or replace it with `slot_returned=1` if the slot was in fact returned. +An advertised retry has to actually be reachable, so the task branch is detached and deleted only *after* the return is proven. +Retiring it first would strip the very branch identity the ship-task identity check asserts, and the retry would come back as an unrelated identity mismatch instead of reaching the recovery. + +For the same reason a record with no resolvable worktree skips that identity check outright: it has no worktree to assert and no slot it could mis-address, so refusing it would hide the reclaim instruction behind an unrelated mismatch and leave an aborted spawn's record permanently unretirable. + +`slot_lease_state=unresolved` is written by an aborted spawn that took a durable lease under the task id but never resolved a slot path, so there is no worktree to record. +Such a record deliberately carries an empty `worktree=` plus `slot_lease_holder=` and, when the settle poll saw one, `slot_worktree_candidate=`. +Teardown retires the endpoint and the records but never returns anything, and prints a `teardown: RECLAIM:` line: find the slot leased to that holder with `treehouse list` and return it per the reclaim steps below. +The lease stays held until an operator returns it, so an aborted spawn can leak a slot but can never hand a live one to another task. + +#### Reclaiming an already-leaked slot + +A slot leaked before that rule existed has no record left to release it: no metadata in any home names it, and its stamp names a task that no longer exists. +Reclaim it by hand, in this order, and stop at the first step that fails. + +1. Confirm nothing records the slot: `grep -l "worktree=<slot>" <home>/state/*.meta` across every home, including secondmate homes, must find nothing. +2. Confirm nothing lives in it: no process under `/proc` declaring `FM_AGENT_TASK` may have that slot as its `cwd`, and `git -C <slot> status` must show no work worth keeping. +3. Read the stamp at `$(git -C <slot> rev-parse --absolute-git-dir)/fm-slot-owner` and confirm the task it names is gone from every home's state directory. +4. Delete that stamp file, then return the slot from its project with `cd <project> && treehouse return --force <slot>`. + +`--force` on `bin/fm-teardown.sh` is deliberately not a shortcut for this. +It is the captain's authority to discard *this* task's work, never authority to release another task's slot, so the gate stays in place and the reclaim stays a deliberate, evidence-checked operator act. + +### Restore-time re-assertion + +`bin/fm-isolation-sweep.sh` re-establishes at session start what spawn could only assert at launch. +It is read-only, returns nonzero for an actionable finding or unproven required process evidence at a possibly live endpoint, and prints one `ISOLATION:` line per blocked task. +`bin/fm-bootstrap.sh` runs it before any mutating sweep, surfaces those lines in the session-start digest, and refuses later mutation until the sweep is clean; the `bootstrap-diagnostics` skill owns what the agent does about each shape. + +Positive location and identity findings come only from an authoritative process reading. +A task with no such reading is normally reported as unproven `ISOLATION:` evidence and blocks mutation; a proven missing, dead, or agent-less endpoint with no live owner conflict is the documented non-actionable exception. `FM_ISOLATION_VERBOSE=1` adds the matching `BOOTSTRAP_INFO` fact; a pane path remains a hint and is never promoted to a violation. + +The sweep first checks for a live process declaring the task with incomplete or +foreign owner-home proof; that is actionable even if the recorded endpoint is +gone. If no such process exists, an endpoint the provider reports as gone or +agent-less has no worker that could act on the record, so the stale record is a +non-actionable `BOOTSTRAP_INFO` fact under `FM_ISOLATION_VERBOSE` rather than a +finding that drops the whole home to read-only. An endpoint that merely cannot +be read is not proof of absence and still blocks, so the gate stays fail-closed. + +Which home a record expects is read from the record, never assumed to be the home running the sweep. +A secondmate declares its own home while its record lives in the launching primary's state directory, so comparing every declaration against this home would report every healthy secondmate in the fleet as a foreign worker on every session start. +A sweep that cries wolf on a normal fleet is worse than no sweep, because the `bootstrap-diagnostics` skill tells the agent to treat these lines as proven. + +## Extension points + +- A new operational-home variable belongs in `FM_WORKER_ISOLATION_HOME_VARS` in `bin/fm-worker-isolation-lib.sh`, not at a call site, or task children will inherit it. +- A new runtime provider that exposes a per-pane process id belongs in `fm_agent_backend_shell_pid` and in the matrix above; one that does not needs no change, because the declaration marker already covers it. +- A new verified harness needs no isolation-specific work, because the declaration is prepended to whatever launch command the adapter builds; the regression suite asserts that for every verified harness so an adapter cannot quietly opt out. + +## Regression coverage + +`tests/fm-worker-isolation.test.sh` covers all four mechanisms: the declaration's exact bytes and its refusals, the launch declaration for every verified harness, each consuming refusal, the process-cwd method of record against a deliberately lying pane path, the provider matrix, the stable-window-id resolution and its refusal to answer from a lost window name, all three slot-conflict forms plus the clean-disposal case, teardown retiring a contested lease under `--force`, the contested-then-released and still-blocked stamp sequences, and the sweep outcomes including a healthy secondmate staying silent, unproven evidence blocking, stale endpoints staying quiet, and live foreign-owner processes still blocking. +`tests/fm-slot-occupant-proof.test.sh` owns focused pooled-slot endpoint proof: exact endpoint selection, PID reuse, foreign and undeclared occupants, closed-endpoint census uncertainty, cross-home metadata, and disposal only after a complete empty census. + +## Maintaining this file + +Keep this file to stable ownership, mechanism boundaries, and the safety rationale a future maintainer needs before changing one of the four libraries. +Exact functions, arguments, flags, and record shapes belong in each script's own header and `--help`, not here. +Dated commands and captured output belong in [`docs/verification/worker-isolation.md`](verification/worker-isolation.md). +Task chronology and delivery proof belong in private task reports or PR evidence. diff --git a/tests/fm-afk-inject-e2e.test.sh b/tests/fm-afk-inject-e2e.test.sh index 3f9791735af..f1da45206bd 100755 --- a/tests/fm-afk-inject-e2e.test.sh +++ b/tests/fm-afk-inject-e2e.test.sh @@ -22,6 +22,10 @@ # # Assert on submitted CONTENT (logged verbatim by the supervisor pane), not pane # appearance — terminal line-wrapping looks like newlines but isn't. +# +# The scenario waits are bounded and event-driven: each poll checks the specific +# daemon/log condition under test, fails quickly if the daemon exits, and prints +# the relevant submitted-log and daemon-state diagnostics on timeout. set -u ROOT="$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)" @@ -106,6 +110,7 @@ submit_line() { } redraw +: > "${LOG}.ready" while IFS= read -r -n 1 _ch; do if [ -z "$_ch" ]; then submit_line @@ -123,7 +128,14 @@ chmod +x "$LOOP_SCRIPT" # Start the loop in the supervisor pane.
