skills: encode the review-chain-stall takeover rule (four conditions) into contract-review.md's clear-equals-land section

[huangyiirene]

Provenance: maintainer ruling 2026-08-31 (director seat summon #7, decision batch #17, verbatim 「同意」 on #13758's option B). Ruling record: #13758 comment 5478594239. Filed by the director seat, session session_01KGtaLpkW1mycWgkbSb3H6t.

The rule to encode (ruled text, carry the substance verbatim)

In .claude/skills/pm-dispatch/references/contract-review.md, the 清标即落地 (clear-equals-land) section gains the stall-takeover clause: when ALL four conditions hold —

1. a review-chain PASS is on record (an at-tier verdict comment on the card),
2. needs:contract-review is cleared on both carriers,
3. the PR's checks are all green (every check, ⛔ not the required subset),
4. the review chain has been stalled past a timeout (no reply to a status probe for more than one patrol interval)

— the dispatching seat may itself flip the PR ready and arm auto-merge, leaving a provenance comment that cites the PASS. Governed surfaces stay draft-only (the terminal four-piece is unchanged). Rationale recorded on #13758: with a PASS on record there is no review left to bypass; the rule exists because a review-chain session interrupt orphaned a green, PASSed PR for four hours (PR #13669, 2026-08-31).

Boundaries

• This is a references/** face edit ⇒ opus-build with fable-tier review per the standing tiering clause; the PR is governed (.claude/**) ⇒ draft-only + human merge / pinned-approval queue path.
• ⛔ Do not widen: the clause covers non-governed code PRs only, and only after a recorded at-tier PASS — it is not a general "dispatch seat may land" license.
• Mind the line ratchet: the skill main file must not grow; this lands in the references file, which is outside the ratchet.

分诊补车道 → domain:skills · p1 · tooling。

锚定。 落点 .claude/skills/pm-dispatch/references/contract-review.md ⇒ 技能根 ⇒ domain:skills（维护者 2026-08-18 裁决：「skills 相关的应该都归你管」）。

定级 p1。 裁决当天已下（batch #17，「同意」option B），且事故是实的 —— PR #13669 一张全绿、已 PASS 的 PR 被评审链会话中断孤儿化 4 小时。这条规则消除的是无活性（liveness）缺陷，不是便利性改进。

⚠️ 与 #13795 冲突：同一天、同一份 skill、两条裁决，后者会架空前者大半

这两张卡都在改 pm-dispatch 的条款② 流程，间隔 4 分钟立卡，各自独立带着「已裁决、可派发」的姿态：

	#13791（本卡）	#13795
立卡	12:48:41	12:53:02
落点	references/contract-review.md	SKILL.md +（grep 命中的）references/**
实质	评审链停摆超时后，派发席可自行 ready + auto-merge，四条件齐备为前提	评审链不再是放行必要条件 —— 契约复核由派发席在席内以 fable 完成

问题在这里：本卡四条件的第 1 条是「评审链 PASS 在案」、第 4 条是「评审链停摆超过一个巡逻周期」。在 #13795 之后，PASS 由派发席自己出，第 1 条与第 4 条同时塌缩 —— 一个不再作为必要条件的评审链，也就无所谓「停摆」。本卡编码的规则会变成一段几乎不可能触发的文本，躺在同一份 references 里，与新流程并列。

⛔ 两张卡不能并行派发 —— 落点重叠（references/** 与 grep 命中面），并行必冲突；更糟的是即使不冲突，也会在同一份章程里留下两套口径。

分诊裁定（排序，非改写裁决）：

1. [skill] pm-dispatch 条款② 复核改制:席内 fable contract review 取代「停靠等外部评审链」,缺位死等成为历史 #13795 先落。 它是更宽的那条，且直接消除无活性。
2. 本卡落地前重新界定范围。 [skill] pm-dispatch 条款② 复核改制:席内 fable contract review 取代「停靠等外部评审链」,缺位死等成为历史 #13795 合并后，重读本卡四条件，把仍然成立的部分写进去 —— 我的判断是「席内复核 PASS 在案 + 双载体清标 + 全绿 ⇒ 派发席 ready + auto-merge」这条主干仍然需要被明文写下（[skill] pm-dispatch 条款② 复核改制:席内 fable contract review 取代「停靠等外部评审链」,缺位死等成为历史 #13795 的第 3 点只说了放行动作，没说四条件的判据形状），只是「等外部链停摆」这个触发条件要换成「席内复核完成」。⛔ 不要按现文照抄。
3. ⚠️ 这个顺序请你确认。 两条都是你今天下的裁决，我只是排了先后、没有改动任何一条的实质；如果你的本意是两条并存（外部链在时走本卡的四条件、不在时走 [skill] pm-dispatch 条款② 复核改制:席内 fable contract review 取代「停靠等外部评审链」,缺位死等成为历史 #13795），说一声，我把本卡改回独立可派发并在两卡上写明分界。

本卡自身的边界，派单时原样保留

• references/** 面 ⇒ opus-build + fable 档复核（standing tiering clause）；PR 属 governed（.claude/**）⇒ draft-only + 人工合并 / pinned-approval 队列。⛔ 不因 [skill] pm-dispatch 条款② 复核改制:席内 fable contract review 取代「停靠等外部评审链」,缺位死等成为历史 #13795 而改变 —— [skill] pm-dispatch 条款② 复核改制:席内 fable contract review 取代「停靠等外部评审链」,缺位死等成为历史 #13795 自己也写明 governed 面停靠不变。
• ⛔ 不得扩宽：只覆盖非 governed 的代码 PR，且只在有在案的同档 PASS 之后。这不是一张「派发席可以自行落地」的通行证。
• 行数棘轮：主 skill 文件不得增长，本条落在 references 文件（棘轮之外）。

Deferred this round, state flipped pm:queue → pm:blocked in the same stroke (skills seat, session session_01Msg17tAHJ3jVTYFgHydCm2, R1).

Blocked-by: #13588

Reason, recorded now rather than re-derived later (a deferral is not a shelving): the landing file .claude/skills/pm-dispatch/references/contract-review.md is HELD by pending human-merge draft PR #13746 (which delivers #13588-A and carries a ratchet raise recorded as 48→51), and merged PR #13812 has since rewritten the same file (in-seat review reform, ratchet now 51→57). Same-file cards hard-serialize across rounds; a third concurrent edit stacks a conflict onto a draft the maintainer has yet to merge.

Known pits for whoever dispatches this after unlock:

1. docs(pm-skill): clause-② CONTENT limb reaches published skills/** — ruled applicability, narrowed criterion #13746 very likely conflicts with current main on this file (both touched the ratchet header and the review-flow sections) — check its mergeable state first; the conflict resolution belongs to that PR's own path, not to this card.
2. The re-scope recorded by triage (comment 5479006050) is in force: after [skill] pm-dispatch 条款② 复核改制:席内 fable contract review 取代「停靠等外部评审链」,缺位死等成为历史 #13795's in-seat reform, conditions 1 and 4 of the ruled four-condition rule collapse (an external chain that is no longer a release precondition cannot "stall"); what still needs encoding is the criteria SHAPE of clear-equals-land — in-seat PASS on record + dual-carrier cleared + all checks green ⇒ dispatching seat flips ready + arms auto-merge — with the trigger re-worded from external-chain-stall to in-seat-review-complete. ⛔ Do not transcribe the four conditions as written.
3. Both underlying rulings are the maintainer's (batch Add comprehensive GitHub Actions automation infrastructure #17 「同意」 option B on [Decision] PR #13669 落地权:契约复核已 PASS 后评审链停摆 >2h,请裁定放行路径 #13758; the 2026-08-31 in-seat reform on [skill] pm-dispatch 条款② 复核改制:席内 fable contract review 取代「停靠等外部评审链」,缺位死等成为历史 #13795). If, on the day, the texts genuinely conflict in intent rather than composing as above, that is a fork → report, ⛔ not a silent re-adjudication.
4. Governed md file ⇒ draft-only + human merge; opus build + fable-tier in-seat review.

Unblock condition: #13588 closes when the maintainer merges #13746 (inherited tail 1 on the seat post) — the standing unlock scan puts this card back in the queue then.
