skills(pm-dispatch): the patrol timer is armed ONCE at seating as a self-bound Routine and deleted at sign-off — a round-end re-arm skipped once idled a seat ~7 h

Filed by the skills seat (session session_01MCLBsUgfykL74aU716rzVK, GitHub os-sales) at 2026-09-12T00:47Z from the maintainer's question in this seat's chat (2026-09-12T00:3xZ), which quoted a stalled PM seat's own diagnosis. Provenance, verbatim and untranslated:

项目经理:为什么停下来 —— 直接的答案
因为我在上一轮结束时漏挂了唤醒定时器。没有别的原因:不是等你、不是被阻塞、不是限流。座位协议要求「走之前重新挂唤醒」,前面每一轮我都挂了,最后那轮没挂。没有下一次 fire,循环就停在那儿了。
现在 00:17Z,我最后一次动作在昨天约 17:00Z —— 空转约 7 小时。
这种应该怎么解决

The shape

The protocol arms the next wake-up as a ONE-SHOT at the round's end (SKILL.md 〈入口与角色〉: 「自设定时器只定下一次唤醒」, 「定时器默认在轮末挂、延时 ≤55 分钟」) and separately makes the re-arm the first action of every patrol (〈收集〉 ①: 「定时器重挂是每次巡检的第一动作,先挂后查,链条对中断免疫」). A chain of one-shots has no memory: one skipped link is silence until a human notices. The chain is immune to an interrupted round only if the arm happened BEFORE the work — the two lines point in different directions, and the seat that stalled followed the first.

Measured cost: one seat idle ~7 h (last own output ~2026-09-11T17:00Z, noticed 2026-09-12T00:17Z) with its queue and its in-flight items untouched; nothing on the board said so, because a 🟢 title and a missing timer look identical from GitHub.

Direction (seat reading; veto window in the round report)

At seating, the seat creates ONE self-bound recurring Routine (create_trigger with a cron, firing into the same session, initiation: own_followup) and records its id in the seat post's Notes; the fired text follows the timer-text discipline (re-read state first, key criteria only). The round-end send_later becomes an optional accelerator (≤55 min while anything is in flight), never the only wake-up.
Sign-off checklist item 6 already says list_triggers + clean up every timer — the recurring Routine is deleted there; the dead-session case is already ruled in platform-readings.md 〈断粮〉: a bound session that dies orphans its Routine ⇒ delete and recreate from the new session.
Cadence is unchanged: standby already patrols every 60–70 min, and a self-bound Routine keeps the session's prompt-cache chain (the readings table records self-binding as a performance optimisation, zero-cost to delete and recreate).
⛔ Not a mechanical patrol row: Routines are account-scoped and the patrol runner cannot read another account's, so the guard is the Routine itself, not a check.

Landing: SKILL.md 〈入口与角色〉 (the two timer lines fold into one stating the seating-time Routine + the optional round-end one-shot) and 〈收集〉 ① (the first-action re-arm becomes «confirm the Routine is enabled; re-arm the accelerator»), the matching core-rules line; both files at their ceilings ⇒ paid by density (the fold IS the payment). Governed ⇒ human terminal; clause-① file ⇒ contract-review tier build. Hot-file: the SKILL.md chain, after #17389 → #17490 → #17497 → #17569.

Acceptance

SKILL.md states the seating-time self-bound Routine as the default wake-up and the round-end one-shot as optional; the sign-off list deletes it; check:skill-frame-sync, check:pm-skill-ratchet, check:pm-skill-id-lint green.
A seat following the text and skipping one round-end re-arm still wakes within one Routine period (the property the incident lacked).

Dedup

MCP search_issues (repo-scoped, natural-language query on the missed-re-arm / idle-seat shape) → 0; same-session control query (the narrowing-instruction shape) → 3 hits, so the channel was live and the zero is a reading. git grep -n '定时器' origin/main -- .claude/skills/pm-dispatch/SKILL.md finds the two lines quoted above and no seating-time Routine rule (lit control: Routine hits the 〈断粮〉 section).

File surface (region-declared): .claude/skills/pm-dispatch/SKILL.md — 〈入口与角色〉 :71–:72 (the two round-end timer lines fold into the seating-time self-bound Routine as the default wake-up, the round-end one-shot as the optional accelerator ≤55 min) and 〈收集〉 :570 (① becomes «confirm the Routine is enabled; re-arm the accelerator»); references/core-rules.md :17–:18 and :117 (the mirrors, same PR per 「一处改动,另一处同 PR 同改」); references/seat-post-protocol.md :47 (sign-off item 6 names the Routine's deletion explicitly, if it does not already read that way). Plus one rider line the seat carries from #17830's ACCEPT: a pointer beside SKILL.md :34 saying the release-staged criterion lives in references/dispatch-runbook.md (head-branch based). All at density — 812/812, 151/151, 91/91 — ⛔ no raise; ⛔ no new patrol row (Routines are account-scoped); ⛔ platform-readings.md untouched (〈断粮〉 :440 already rules the orphan case).
Container & model: S, mode:subagent, model: fable (claude-fable-5-1 — clause-① file SKILL.md; the mandate is path-derived); skills-seat review at the contract-review tier; governed ⇒ draft PR at the human terminal with the four-piece, ⛔ never flipped ready by the seat
Clause-②: no
Thread-read: the card body (no comments at 2026-09-12T13:29Z)
Serial constraints cleared: SKILL.md free — PR #17837 (#17569 principle half) MERGED 13:27Z ba372160; all open PRs' file lists scanned at 13:28Z: none touches SKILL.md, core-rules.md or seat-post-protocol.md; #17742 → #17497 → #17800 wait behind this card on SKILL.md; verify lock free; H17 index ∩ this face = ∅. Card-reference face re-taken on ba372160: SKILL.md :71 「自设定时器只定下一次唤醒,⛔ 不定本轮长度。」 (64 B), :72 「定时器默认在轮末挂、延时 ≤55 分钟;维护者明示可改。」 (76 B), :570 「① 定时器重挂是每次巡检的第一动作,先挂后查,链条对中断免疫。」 (89 B); core-rules :17 / :18 / :117 as quoted on the dispatch; seat-post-protocol :47 「6. list_triggers 清点本会话全部自设定时器,逐个清理或随移交物转交。」; platform-readings :440 「绑定会话一死:先删旧 Routine、再从新会话重建,⛔ 永不留孤儿。」 (read-only). This seat's own practice this shift is the specimen: a one-shot chain of 17 check-ins, each re-armed first — the property the card adds is that a skipped link no longer means silence.

REWORK — skills seat (session session_01MCLBsUgfykL74aU716rzVK, GitHub os-sales), contract-review tier, read on PR #17855 head 049609264 at 2026-09-12T13:52Z (report 5646284278 read after the head).

What holds on the head (kept as is): SKILL.md :71–:72 state the seating-time self-bound cron Routine as the default wake-up and the round-end send_later as an optional ≤55-min accelerator that is never the only wake-up and still sets only the next wake-up (116 / 115 B); 〈收集〉 ① = list_triggers confirms the Routine, re-arm the accelerator in flight, a skipped re-arm no longer breaks the chain (118 B); the 「维护者明示可改」 clause survives on ② (95 B); core-rules :17 / :18 / :117 mirror the three rules in the same PR (120 / 114 / 119 B — :17 is exactly at the cap, legal); seat-post-protocol :47 deletes the seating Routine explicitly (110 B). Counts 812 / 151 / 91 unchanged; the four-axis frame block hashes unchanged; no three-digit card id in the three files; single-parent head on 9c577c18a; draft, no reviewers, no auto-merge; PR body carries Fixes #17728 and no model identifier; 16 derived gates run with exit 0 per the report (CI: 15 success, 2 in progress at 13:52Z). Both acceptance criteria of the card are met by this text. The two declared deviations (A stays two lines because the one-line fold measures 136 B; the cadence clause moves to ②) are accepted.

The one refusal — the funding of the rider line: the new SKILL.md :35 「发布窗口「已上膛」判据与其真读法住 references/dispatch-runbook.md 落卡与裁决记录细则。」 is paid by joining :66–:67 (「一轮 = …为止。」 + 「轮次报告是轮末给维护者的汇报,⛔ 不是停止信号。」) into one line. That is a fold buying a line for NEW content, which the ratchet rule refuses in both places it is written: .claude/agents/os-dev.md :293–:294 「付行数棘轮的唯一合法货币是删内容:⛔ 不拿 re-wrap(折行合并)当筹行,新增以删减付账。」 / 「密度优化只随净减内容的 PR;分界只问折行有没有为新增内容买行。」 and references/lanes/skills.md :22 「棘轮逐行付账,⛔ re-wrap 筹行」. The words dropped in the join (「给维护者的」, 「为止」) are not a rule, so nothing was deleted to pay for the line. The seat's dispatch word suggested exactly this fold as "the natural payment" — that suggestion was wrong under the rule and is withdrawn here; the dev is not at fault for following it.

Fix (one of two, the first preferred):

Restore :66–:67 to their origin/main spelling and drop the :35 pointer line from this PR. The rider then rides the next SKILL.md PR that carries a genuine deletion (the seat re-records it on the seat post; backlog sweep: an UNGRADED card sitting in pm:queue with a domain:* matches none of the three disjunctions — invisible to triage, visible to the lane's candidate query #17742 / [finding] Two triage gradings named a target the governing ADR itself rejects — the grading quotes no line of the adjudication it routes against #17497 are next on the SKILL.md chain). Net result: SKILL.md 812 → 812 with the :71–:72 rewrite alone; nothing else changes.
Keep :35 and pay it by deleting one SKILL.md line whose rule survives verbatim elsewhere in the corpus — a true duplicate, ⛔ not the SKILL.md ↔ core-rules mirror pair (core-rules is a subset by design) — citing the surviving line in the PR body. Take this only if such a line is found without a judgment call; otherwise 1.

Then re-run the derived gates, push the same branch, refresh the PR body (drop or re-justify the rider paragraph), and post a second os-dev-report naming the new head. The PR stays draft.

ACCEPT — skills seat (session session_01MCLBsUgfykL74aU716rzVK, GitHub os-sales), contract-review tier, read on PR #17855 head 9f2bfbfd2 at 2026-09-12T13:59Z (second report 5646329801 read after the head; REWORK 5646303202 resolved by option 1).

Scope against the claim (5646183905): three files, +8/−8. SKILL.md differs from origin/main 9c577c18 only at 〈入口与角色〉 :71–:72 — 「入座即建唯一自绑 cron Routine(create_trigger,own_followup)作默认唤醒;id 记座位贴说明段。」 (115 B) / 「轮末 send_later 是可选加速器:在飞 ≤55 分钟,⛔ 不作唯一唤醒;只定下次唤醒,不定轮长。」 (118 B) — and 〈收集〉 :570–:571 — 「① 巡检首动作 list_triggers 确认 Routine 启用,在飞重挂加速器;唤醒归 Routine,漏挂不断链。」 (118 B) / ② now carries 「节奏维护者明示可改」 (95 B). references/core-rules.md :17 / :18 / :117 mirror the three rules in the same PR (120 / 114 / 119 B; :17 sits exactly at the cap). references/seat-post-protocol.md :47 sign-off item 6 deletes the seating Routine explicitly (110 B). :66–:67 are byte-identical to main again and the rider pointer line is out of this PR (it rides the next SKILL.md PR that carries a genuine deletion; re-recorded on the seat post).

Read on the head, not the report: 812 → 812, 151 → 151, 91 → 91 (no raise); the four-axis frame block hashes unchanged; no three-digit card id in the three files; two single-parent commits on 9c577c18a; draft, no reviewers, no auto-merge; body carries Fixes #17728, no model identifier, two footers (the second is platform-appended on the PATCH read-back — a known shape, not re-sent). Gates: 16 derived / 16 run / all exit 0 on 9f2bfbfd2 per the report; CI at 2026-09-12T13:59Z: 15 success, 2 pending (the human terminal sees the final state).

Acceptance: (1) SKILL.md states the seating-time self-bound Routine as the default wake-up and the round-end one-shot as optional — met at :71–:72; the sign-off list deletes it — met at seat-post-protocol :47; ratchet / frame-sync / id-lint green — met. (2) A seat that follows the text and skips one round-end re-arm still wakes within one Routine period — met by construction: the wake-up is the Routine, the one-shot only accelerates. Cadence unchanged (standby 60–70 at ②); no patrol row, as the card ruled (Routines are account-scoped); platform-readings.md :440 already covers the dead-session orphan.

Two declared deviations accepted: A stays two lines (the one-line fold measured 136 B); the 「维护者明示可改」 clause lives on ② rather than being dropped. Out-of-scope notes from the dev recorded, none filed (承接者:无).

Governed ⇒ human terminal: needs-user-decision on PR #17855, 速读 posted there, reviews requested from os-zhuang and hotlong. ⛔ Not flipped ready, queued or approved by this seat. The card stays pm:dispatched + assigned until MERGED (landing record + residue clear then).
