Speaking as Kun's firstmate: Reviewed HEAD Class: corrective. VISION (per rule, inspected evidence):
Does not claim / does not close #3149 (already closed by merged #3155). Related to declared-wait cadence work but is the live-endpoint bare-queue leak, not the daemon busy-pane override. Leftover overlap with open #2738 (Omar-Nawaf): both change Issue close: no ready-for-pr issue is named as Fixes/Closes in the body; not treating fetch metadata as proof of close. Attestation: First-time fork CI: after that full-diff review I approved workflow runs Not merging. Overlap leftover with #2738 and attestation mismatch. Waiting on the author. Not with the captain.

The `PR must be raised via no-mistakes` check failed on this PR with "Pipeline attestation head_sha does not match the current PR head": attestation.head_sha 6f20841, PR head 9883b55. That is not specific to this PR. GitHub snapshots the pull request body into the event payload when the event fires, and the pinned require-no-mistakes action judges that snapshot. no-mistakes pushes the branch first and only rewrites the body with the new head's attestation about two minutes later, so the `synchronize` payload always still names the previous head. Every synchronize run of this workflow in recent history failed and was followed by an `edited` run that passed, leaving a permanent red check beside the green one - PRs kunchenguid#3160, kunchenguid#3184, kunchenguid#3173, kunchenguid#3132, kunchenguid#3064, kunchenguid#3168, kunchenguid#3183, kunchenguid#3127 and kunchenguid#3166 all show the pair. Judge the live body instead. bin/fm-attestation-settle.sh re-reads the PR body until its v1 attestation binds to the pushed head, then hands what it settled on to the action through the `pr-body` input the action already exposes for exactly this. It renders no verdict of its own: the pinned action stays the only thing that can pass or fail the gate, so a push no-mistakes never attested still fails, just after a bounded wait, and an unreadable body sends the action back to its event-payload default. The workflow checks out the base branch, never the PR head, so the gate still never runs code from the pull request it is judging.

Speaking as Kun's firstmate: Re-verified newer activity. HEAD is now Class: corrective for the watcher leak. The branch also changes the repo-wide required gate: settle the live PR body via VISION (per rule, inspected evidence):
Overlap hold: open #2738 (Omar-Nawaf) still edits the same Attestation: CI: current-HEAD run Not merging. Waiting on the author for green CI, and on the leftover overlap with #2738. The gate settle is a captain decision only if this PR becomes otherwise ready. Not with the captain now. |

A `paused:` declaration on a LIVE endpoint was downgraded to `none` by pause_state_class's endpoint-liveness gate, purely because the agent process still existed. `none` routes the caller's first sight of each new pane hash through surface_nonterminal_stale, and a live harness footer mints a new hash on every capture, so the declared wait enqueued a bare `stale: <window>` record - one burned handling turn - per tick, while the polls in between logged the very same declaration as `absorbed stale (paused, awaiting external)`. The worker's own declaration is now authoritative for enqueue: an unchanged `paused:` line takes the bounded cadence whatever the backend reports about endpoint liveness. Wedge detection is preserved on every path: - handle_paused_stale still re-surfaces the pane once per PAUSE_RESURFACE_SECS, naming the wait's age, so a live wedge behind a declared wait is still reported rather than hidden. - An authoritative working verdict still outranks a stale pause and restores the wedge timer once the recheck window lapses. - Lifting the declaration returns the pane to ordinary wedge handling on the next poll. - A durable `captain-held` transfer keeps the stricter confirmed-dead gate, so a live decision gate still surfaces at once. - A pane carrying no declaration is untouched.

Two review findings on this branch: - pause_state_class resolved `window_kind` eagerly, before both new `status_is_paused` branches that return without ever using it, so every declared-wait stale poll paid an avoidable metadata read. It is now resolved lazily and memoized: a `paused:` wait scans nothing, while a captain-held pane reaching both liveness gates still scans exactly once. - The live-recheck loop in tests/fm-watch-triage.test.sh called bare `wait` on a watcher that `wait_poll_cycle` gave up on. That helper returns non-zero both when the process exits and when its budget lapses with the process alive, so the second case would hang the suite instead of failing it in bounded time. The loop now reaps and fails in that case, matching the pattern the dead-agent block in the same test already uses. Claude-Session: https://claude.ai/code/session_01ECmPVoFGBMph2nSNZNajVS

The public-followup fixtures hard-coded absolute timestamps, so the seeded thread window silently flipped from open to expired the moment its date passed. That turned every rechain test into a time bomb: once 2026-08-28T01:12:00Z went by, `rechain` correctly refused the seeded loop as unreachable and the suite failed on a change that had nothing to do with it. Derive the received, follow-up expiry, and obligation retention timestamps from the moment the suite starts, so each fixture keeps its intended meaning on every future run. The expiry-escalation test now reads the same seeded window instead of duplicating the literal, so the pinned-clock assertions cannot drift away from the seeder.

Intent
Stop absorbed paused-task stale wakes at the source in firstmate.
Observed with four parked tasks awaiting external humans: four bare
stale: default:wNN:p2wakes arrived back to back, each burning a full handling turn (drain, confirm the unchanged external wait, acknowledge) while nothing about any of those tasks had changed.state/.watch-triage.logshowed the watcher correctly decidingabsorbed stale (paused, awaiting external, age Ns)for those panes repeatedly, yet the rewake still delivered each one as a barestale:wake with no paused annotation, interleaved with the deliberate long-cadence rechecks for the same task - the hint that two producers were enqueuing for one decision.Required work, all of which this branch carries:
Accepted decisions carried forward from earlier rounds of this same work:
This round additionally fixes the one remaining red check, which is not caused by the change above. tests/fm-public-followup.test.sh failed on
rechain failed:because its fixtures hard-coded absolute timestamps (followup_expires_at: 2026-08-28T01:12:00Zand--expires-at 2026-10-01T00:00:00Z). Those are time bombs, not a slow-shard race: once the literal date passes,rechaincorrectly refuses the seeded loop as unreachable and the suite fails permanently on a change unrelated to it. The fix removes the dependence on wall-clock timing by deriving the received, follow-up expiry, and obligation retention timestamps from the moment the suite starts, and by having test_expiry_escalation_uses_now_override read the same seeded window instead of duplicating the literal. Widening a timeout or retrying was explicitly ruled out.Also in this round: the pull request title was changed from the placeholder "chore: update pull request" to a real semantic title.
This repository is firstmate's own shared tracked material, so changes follow .agents/skills/firstmate-coding-guidelines/SKILL.md.
Known expected non-failure, do NOT chase it: firstmate pull requests go from the captain's fork to the upstream repository, and their CI and "Require no-mistakes" workflows PARK at action_required. Approving those parked runs needs repository admin the captain does not have (his own call returns 403). Do not edit shared tracked material trying to make parked runs green - that has already been caught twice on this fleet. A delivered pull request whose runs await an owner approval is a complete result. Keep the no-mistakes attestation intact. Do not merge.
State of this branch at the start of this run (head 2c84a74): every substantive check already passed on the immediately preceding head - 13 of 14 green including Greptile Review, Lint, Repo invariants, the macOS Bash snapshot compatibility check, and all behaviour test shards. Two review findings on pause_state_class in bin/fm-watch.sh were already raised and fixed in earlier rounds: first, that the fresh-recheck fast path bypassed the authoritative crew state, so a resumed task stayed classified paused and lost its wedge timer; second, that the resulting authoritative-working fast path pre-empted the stricter captain-held endpoint-liveness gate, so a live captain-held decision was absorbed behind the wedge timer instead of surfacing immediately. Both are fixed: a captain-held line now hits the liveness gate first and returns none for immediate surfacing, while a paused: line skips that gate and keeps its liveness-independent absorption, its long-cadence recheck, and the working-outranks-declaration rule; tasks with no declaration are untouched. A later round also removed a five-line duplicate working-check in the same function that had become unreachable once the working check moved above the recheck block; that deletion is dead-code removal only and the captain verified it himself.
The only reason this run exists: the previous run's CI monitor pushed fix commits without ever republishing the PR body attestation, so the required "PR must be raised via no-mistakes" check kept being judged against an older head_sha and stayed red, which the monitor then re-read as an issue and auto-fixed again. The supported rebind path was tried and refused - git push no-mistakes returned "Everything up-to-date" because the gate remote already held the pushed head. On the captain's explicit instruction the stalled run was cancelled, branch ownership was confirmed returned through structured status, and this single fresh run is started at the current head so its own push and pr steps republish the attestation bound to the head actually being validated. Validate exactly once against this final head.
Explicitly NOT authorized in this round: hand-editing the attestation block in the PR body, force-pushing, --admin, disabling or editing the gate workflow, and merging. Do not collapse the duplicated endpoint-liveness recovery gates in pause_state_class; that remains the captain's deliberate follow-up.
What Changed
paused:waits authoritative in watcher triage, preventing absorbed stale wakes while preserving bounded rechecks, genuine wedge detection, and undeclared-task behavior.Risk Assessment
✅ Low: The source changes satisfy the stated stale-wake behavior and preserve wedge, recheck, non-declared, and captain-held paths; the only substantiated issue is a test-quality violation in newly added workflow assertions.
Testing
Ran the targeted watcher triage and public-followup behavior suites, including absorbed paused stale suppression, bounded rechecks, wedge preservation, churning-pane handling, authoritative working recovery, rechain, and time-relative expiry behavior; all passed with no actionable findings.
