 ## Gate defaults (.no-mistakes.yaml)
 
-The tracked `.no-mistakes.yaml` sets `test.evidence.store_in_repo: true` and pins `commands.lint` to `bin/fm-lint.sh`, the same owner CI invokes.
+The tracked `.no-mistakes.yaml` enables `jev.review_assist: true` for advisory pre-brief context in the review step only, sets `test.evidence.store_in_repo: true`, and pins `commands.lint` to `bin/fm-lint.sh`, the same owner CI invokes.
+The existing review remains the merge-gate decision point; Jev does not gate delivery.
 Storing evidence in the repo publishes each run's test artifacts to the orphan `no-mistakes/evidence` branch and links them from the PR body, instead of keeping them on local disk under the no-mistakes home.
 That branch shares no history with code branches, so evidence never enters a pushed feature branch or the default branch; the worktree's `.no-mistakes/` stays local and CI rejects tracked entries under that path.
 The [`firstmate-coding-guidelines` skill](../.agents/skills/firstmate-coding-guidelines/SKILL.md#no-mistakes-test-configuration) owns why `commands.test` stays absent and targeted validation belongs to the evidence path.

-The three arms that still report 0 need a presence re-read taken after their own close, and the close-then-read timing that re-read depends on cannot be established without the real Zellij, Orca, and cmux binaries.
-Guessing it is what a refusal must never rest on: a gate that refused an already-exited session would break ordinary cleanup on every task, which is a worse failure than the stranded endpoint it would be trying to prevent.
+| orca | 0, silent when the terminal handle is definitively stale | 1 when the CLI, close, or stale-handle re-read cannot prove absence |
+| zellij | 0, silent when the session is absent | 1 when the close or scoped tab/pane proof cannot prove absence |
+| cmux | 0, silent when the recorded workspace is absent | 1 when the close or scoped workspace proof cannot prove absence |
+| herdr | 0, silent when the exact recorded pane is confirmed dead | 1 when the exact pane presence is unknown or live |
+
+Every arm now performs its backend-specific absence proof after close.
+Zellij requires the recorded task label and confirms that both the scoped task tab and recorded pane are absent.
+cmux requires the recorded task label and confirms that both the scoped task workspace and recorded workspace are absent.
+Orca accepts only the documented stale-handle read result.
+Any missing, unreadable, or ambiguous proof returns 1 rather than passing for absence.
 tmux's re-read is deliberately exact - `=session` plus a whole-line window-name match - because a prefix match would read a neighboring window as this window's survivor, which is the same exactness the cleanup identity boundary above already requires.
 It is also deliberately conservative about the read itself, sharing `fm_backend_tmux_window_inventory` with `fm_backend_tmux_agent_state` so both mean the same thing by an absent session: only a definitive missing-session, missing-server, or connect-error response proves the window gone.
 Any other read failure - a momentarily unresponsive server, or a teardown PATH without tmux on it - refuses, because a read that could not run is not evidence of absence.

Verified against no-mistakes v1.79.0's own e2e tests and upstream PR #1120:
jev.review_assist is global-only and has no effect when set in a repo's
tracked .no-mistakes.yaml. Revert that no-op change and document the real
activation path, data sent, and data-boundary guidance instead.

+It also needs `TYPESAFE_API_KEY` set in the daemon's environment; without a key the step log says so and review proceeds without a pre-brief, exactly as when the setting is off.
+On every call failure, oversized reply, or missing key, no-mistakes falls back to the ordinary cold review with no pre-brief - this repo does not depend on Jev being reachable.
+
+**What is sent.** Per review turn, no-mistakes sends the diff of the files under review (never files matched by this repo's `ignore_patterns`, which are not "reviewable") plus up to 40 candidate file paths - paths only, never their content - ranked by name rarity and directory proximity. No project name, PR body, or brief text is part of this call.
+
+**Data boundary.** This repository's captain-private and gitignored paths (`.env`, `data/`, `state/`, `config/`, `projects/`, `.no-mistakes/`) are untracked, so they can never appear in a git diff and are never reachable by this or any other diff-based review path.
+The remaining operator responsibility is ordinary git hygiene: keep secrets out of tracked files, since no-mistakes has no Jev-specific secret redaction beyond the review step's existing findings pipeline.

+- userOutcomeReview: The self-hosted Discord path violates its downstream owner-only trust contract. With no channel allowlist configured, the poller enumerates accessible guild channels and DMs, accepts any non-bot author who mentions or DMs the bot, and emits the same `x-mention` payload consumed by `fmx-respond`. That consumer explicitly treats every direct author as the captain and autonomously performs normal lifecycle work. No author-id or role check exists in the introduced poller.

+   - observation: Any Discord user able to DM the bot or mention it in an accessible channel is converted into a captain-authorized request. The default configuration scans guild channels and enables DMs, while the poller checks only `author.bot`, mention/DM status, and channel exclusion. The shared response skill then treats the direct author as the captain and may file work, dispatch agents, investigate, or ship gated changes.
+   - bypass: Send a DM to the bot, or mention it in any channel visible to the bot, without being the operator/captain.
+   - consequence: An untrusted Discord user gains authority to trigger autonomous replies and normal reversible lifecycle actions on the operator's machine; the system may also expose public-safe operational outcomes to that user.
+
+## Notes
+
+- Jev: tracked `.no-mistakes.yaml` sets `jev.review_assist`, but the branch documentation states this key is global-only and ignored from repository config. No reachable new Jev disclosure path was established from this repository change.
+- Wake/state and external command paths: no additional source-backed security or privacy finding was established in the reviewed changes.
+- remove-ai-slops/programming direct pass: The Discord boundary uses no author authentication and relies on a downstream hosted-Relay invariant that the self-hosted adapter does not establish. Tests cover channel selection, DM defaults, and delivery, but do not prove an owner identity boundary. No slop-only concern is promoted as a blocker.

 **What is sent.** Per review turn, no-mistakes sends only the diff of reviewable files plus up to 40 candidate file paths - paths only, never their content - ranked by name rarity and directory proximity. No project name, PR body, or brief text is part of this call.
 
-**Data boundary.** This repository's captain-private and gitignored paths (`.env`, `data/`, `state/`, `config/`, `projects/`, `.no-mistakes/`) are untracked, so they can never appear in a git diff and are never reachable by this or any other diff-based review path.
+**Data boundary.** The review step selects reviewable files according to its diff and ignore rules; paths matched by those rules are not sent to Jev. Gitignored status alone is not a guarantee, because tracked or force-added files can still be reviewable.
 The remaining operator responsibility is ordinary git hygiene: keep secrets out of tracked files, since no-mistakes has no Jev-specific secret redaction beyond the review step's existing findings pipeline.
 
 **Audit.** The review step log already records whether a pre-brief was requested, whether it was used, and the reason for any fallback (`no-mistakes axi logs --step review --full`); no separate Jev-specific audit log exists in this repo, since the call itself happens inside the no-mistakes daemon process, outside firstmate's own scripts.

 A crew that declared an external wait (`paused:`) or a verified captain-held transfer is the first exception to that bound: its busy verdict supplies liveness while identifying the long-running foreground call as the declared wait, so it takes the bounded `FM_PAUSE_RESURFACE_SECS` recheck instead of a wedge escalation, except that a captain-held transfer is not rechecked while the away-posture record exists.
 In a home that armed `config/wedge-defer-parked-gate`, a crew whose own validation gate awaits the supervisor's still-open decision for that run is the second, reached through the shared wedge timer rather than the declaration branch, because who owes that answer does not depend on what the pane is rendering; it takes the same bounded recheck, including while the away-posture record exists.
 Lifting the declaration restores the unchanged busy-pane wedge path, while a pane that is no longer busy returns to the existing idle declared-wait classification.
-While the legacy daemon flag is active, a busy pane that crosses the bound under a declared external wait is handed to the daemon as the plain wake identity instead of taking that recheck in the watcher, because the daemon owns triage there and a wake already decorated as a possible wedge would override the daemon's own declared-wait verdict; an undeclared busy pane past the bound still takes the wedge escalation.
+On a harness that runs the away daemon, while the legacy daemon flag is active, a busy pane that crosses the bound under a declared external wait is handed to the daemon as the plain wake identity instead of taking that recheck in the watcher, because the daemon owns triage there and a wake already decorated as a possible wedge would override the daemon's own declared-wait verdict; an undeclared busy pane past the bound still takes the wedge escalation.
 That handoff is keyed on the declaration itself (the status log's signature) rather than on the pane capture, so a harness footer that ticks on every poll wakes the daemon once per declaration instead of once per poll, and it clears the wedge timer, escalation count, and worktree-write deferral exactly as the normal-mode absorber does, so an undeclared busy phase's timer does not resume when the declaration lifts.
 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.
 Agent endpoint liveness and queue-consumption liveness are separate: on each poll, the primary watcher reads the oldest valid actionable row from every endpoint-recorded local secondmate home's durable wake queue without locking, consuming, or rewriting that foreign queue.

 The turn-end guard closes the remaining gap at the primary's own turn boundary.
 When work, a process-event source, a registered custom check, or Relay polling needs supervision at that boundary and no identity-matched watcher has a fresh beacon, the harness integration must either block the turn end or force one bounded follow-up that uses the recovery instruction from the emitted session-start protocol.
 The mid-turn pull warning uses the model-aware supervision verdict described below, while the turn-end guard keeps the PID-strict watcher predicate.

 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.

-While `state/.afk` exists the daemon (`bin/fm-supervise-daemon.sh`) owns supervision and runs the watcher one-shot, in either away or quiet mode: the watcher exits on every wake and the daemon starts its replacement, so a turn boundary regularly lands in a hand-off where no watcher process holds the lock and nothing is wrong.

 The turn-end guard therefore accepts `fm_afk_daemon_owns_supervision` from `bin/fm-wake-lib.sh` as proof of supervision on that path: `state/.afk` must exist (the predicate does not distinguish away from quiet mode), and this home's `state/.supervise-daemon.lock` must name a live pid whose current process identity still matches the identity the daemon recorded for itself.
 That is the same identity discipline the watcher lock uses, so a recycled pid, a lock left behind by a killed daemon, and a daemon that never recorded its identity all fail it.
 A daemon that cannot record its own identity at startup logs a warning and keeps running, because a supervisor must not refuse to run over an unreadable `ps`; that warning is what names the cause when the guard then keeps blocking away/quiet-mode turn boundaries for the rest of that daemon's life.

Subject: [PATCH 16/16] no-mistakes(ci): Fixed the CI failure in
 tests/fm-secondmate-sync.test.sh by making the Herdr fixture provide
 session-lock metadata and model pane-close disappearance, allowing respawn
 metadata to rotate. Verified with the targeted sync test,
 fm-backend-herdr.test.sh, bash -n, and git diff --check
