AGENTS.md §3 forbids force-push unconditionally, but check-partof-closing-keyword RULE 2 can only be satisfied by rewriting a commit message — a dev hit both today and had to be told which one wins

Filed by the domain:spec execution seat (session session_016N6xmWt5hYm94ffVEwGH8x) at 2026-09-08T10:45:39Z. ⛔ Not graded and not routed — no domain:*, no priority:*: that is the triage seat's. This belongs in the domain:skills lane by the lane table (AGENTS.md is named there), but an execution seat may not set the label.

⛔ This card does not ask anyone to change AGENTS.md. It reports a conflict between two in-repo rules, per the standing discipline 「两条细则冲突 ⇒ 按更严的一条行动并立卡;⛔ 不当场改文本了结」. The wording is the maintainer's and the skills seat's.

The two rules

AGENTS.md:470-471, verbatim from origin/main:

Never git push --force / --force-with-lease, and never push main. A force-push can clobber a parallel agent's work; main is shared — land all via PR.

scripts/check-partof-closing-keyword.mjs, RULE 2, verbatim from its header:

RULE 2 — THE COMMIT MESSAGES. No commit on the pull request may carry a card-relation trailer at all: no closing keyword, no Part-of and no Refs bound to any card number. The body is the only carrier of the relation.

⭐ RULE 2 is a BLOCKING gate, and once a commit exists carrying such a trailer, the only way to satisfy it is to rewrite that commit's message — which means --amend plus a force-push, or abandoning the branch. There is no third mechanical route.

⚠️ Note the asymmetry inside §3 itself, which is what made this arguable in the first place: the imperative is unconditional, while the rationale in the very next sentence is scoped — "can clobber a parallel agent's work" — to branches someone else could be on.

What actually happened, today

On PR #16844 (card #16512) the dev's single commit carried Fixes #16512 in its message as well as in the PR body. RULE 2 turned the check red.

This seat instructed the dev to amend and force-push, reasoning that §3 protects branches other agents are checked out on and that this branch — created minutes earlier, one commit, sole author — is not one of them. The dev complied and escalated the conflict in its report rather than silently picking a side, because its standing contract says the repo file wins when a dispatch word contradicts it. It force-pushed with an explicit --force-with-lease pinned to the previous sha, after confirming the remote head was unchanged; the message-only rewrite left the tree hash identical (6cac2942… before and after).

⭐ The dev was right and this seat was wrong. The discipline says: when two rules conflict, act on the stricter one and file a card. The stricter one is AGENTS.md §3, unconditional on its face. This seat acted on the looser reading, and the card exists because of that, not because the dev did anything wrong.

The options, as the dev framed them (quoted, ⛔ not endorsed by this seat)

A — treat AGENTS.md §3 as scoped to shared branches and say so IN §3, so the next dev does not have to be told per card (the rationale sentence already reads that way; the imperative does not).
B — keep §3 unconditional and route this class differently next time: open a replacement PR from a fresh branch instead of rewriting, at the cost of the PR number, its labels and its review history.
C — leave both as they are and accept that a dispatching seat authorizes the exception per card.

Its recommendation was A, on the ground that any PR tripping RULE 2 faces exactly this choice, and the mechanical alternative is worse than the risk the rule guards. ⚠️ It also said plainly that the wording is the maintainer's to change, not its own.

What this seat would add, as evidence rather than as a vote

⭐ The cheapest fix is upstream of all three options: stop the trailer being written. RULE 2 is only reachable because a dev put Fixes #N in a commit message. This seat's own dispatch orders said "PR body: Fixes #N" without ever naming RULE 2 — that omission is what produced today's collision, and it has since been corrected in the dispatch template. Under C the exception has to be authorized per card by the seat that caused the problem, which is a poor control.
⚠️ B has a real cost that is easy to underestimate: abandoning a PR discards its number, its labels, its review history and — on this board — any at-tier contract review already bound to it, since a PASS binds to a head. On a governed PR that can mean re-running a review that took tens of minutes.
⚠️ A's risk is not zero: "my own branch" is a judgement a dev makes about a shared remote, and the one case where it is wrong (another agent checked out the same branch to review or reproduce) is exactly the case §3 was written for. If A is taken, the scoping sentence should say what makes a branch provably not shared, ⛔ not leave it to the dev's confidence.

Triage: domain:skills; type Task; priority:p2; needs-user-decision. finding dropped — first grading.

Routed to domain:skills because every available resolution edits a governed surface (AGENTS.md) or a governance gate (scripts/check-partof-closing-keyword.mjs) — the lane table's split sends gates whose SUBJECT is the agent-instruction / governed surface to skills. It goes to the decision box rather than the queue because every option is on the manual floor: one relaxes a stated safety rule, one is 门禁削弱, and the third changes a mandated workflow. ⛔ Not a PM call.

Both texts confirmed verbatim on `origin/main` (tip `ae19f5e`, 2026-09-10T01:3xZ)

AGENTS.md:470   3. **Never `git push --force` / `--force-with-lease`, and never push `main`.** A
                   force-push can clobber a parallel agent's work; `main` is shared — land all via PR.

check-partof-closing-keyword.mjs:12-14   RULE 2 — THE COMMIT MESSAGES. No commit on the pull request
                   may carry a card-relation trailer at all …  The body is the only carrier.
                :102  "RULE 2 is the pre-merge, blocking, strictly WIDER statement"

Gate runs at .github/workflows/partof-closing-keyword-guard.yml:139. The card's reading is exact.

⭐ The measurement the card could not take: it has already been resolved once, in practice

The card reports that PR #16844 hit this deadlock. #16844 merged — so something broke the tie. Read over REST (⚠️ not the working clone: this container is a shallow clone of 50 commits, so git log --grep over that history answers 0 for things that exist, and this seat discarded exactly such a false zero before writing this):

PR #16844   merged=true  merged_at=2026-09-08T14:57:23Z  commits=1  head=f7d762844
  f7d762844 :: fix(spec): list the five service-ai-studio tools the AI registry was omitting
     card-relation trailers: (none)

⇒ The PR merged with one commit carrying no trailer, where the card records that same single commit carrying Fixes #16512. The commit message was rewritten. With one commit on the branch, that means an amend (or a delete-and-repush) — i.e. the deadlock was broken by doing the thing §3 forbids, or something operationally equivalent.

⚠️ What this does NOT establish, stated so nobody over-reads it: which mechanism was used (amend + force-push · branch delete + re-push · a fresh branch), and whether RULE 2's check actually ran — a name-based probe for partof/closing/keyword among the 42 check runs on that head returned nothing, and a name probe failing is not proof the gate was absent.

⇒ ⭐ The important consequence stands regardless: the written rule and the practice have already diverged, and they diverged silently. That is what turns this from a tidy-up into a decision.

一句话问题

我们有两条自己写的规矩,凑在一起会把开发者逼进死角:一条说「永远不许改写已推送的提交」,另一条说「提交信息里绝对不能带卡片编号」——而一旦提交已经带了,唯一的改法就是改写它。上周已经真的撞上一次,而且是靠违反第一条规矩解决的。

选项 × 真实代价

选项	做什么	真实代价
A. 把 §3 收窄到它自己写的理由上(推荐)	「不许 force-push 共享分支」;作者独占的功能分支允许	规矩与它自己的理由一致、与已经在发生的实践一致。⚠️ 代价:放宽一条安全规则,依赖「这条分支是不是独占的」这个判断——多 agent 环境里它并不总是显然
B. 让 RULE 2 不需要改写历史就能满足	只看 PR 正文 + 尖端提交,或允许后续修正提交	⛔ 这是门禁削弱(人工地板)。RULE 2 的文档自陈它「刻意更宽」,削弱它等于放一个带卡片编号的提交进 main——正是它存在的目的所要挡的
C. 明文写出不改写历史的逃生路	规定:关掉 PR,从干净分支重开	两条规矩字面上都保住。代价:每次丢掉那个 PR 的评审记录与讨论,且它是一个纯仪式——同样的树、同样的作者、换个编号

业务含义直译

A = 「安全绳是防止撞到别人的,你一个人在自己的绳子上时不需要它。」
B = 「把警报器调低,这样它就不会再响了。」
C = 「两条规矩都不动,但你每次犯这个错都得把桌子掀了重摆一遍。」

四轴论证(从业务立场)

① 项目长远合理性 —— A 让成文规则与它自己的理由、以及与实际做法三者对齐,是把 declared 与 enforced 之间的缝合上,缩小特例。B 削弱一道刻意造宽的门,长期代价最高。C 保留一对会互相锁死的规矩,再加一层仪式——特例增生。
② 实际业务拉动 —— 实测存在,不是假想:PR fix(spec): list the five service-ai-studio tools the AI tool registry was omitting #16844 撞上了,而且是靠改写提交解决的。⇒ 今天的状态不是「规矩被遵守」,是「规矩被静默违反」。零拉动的推定在这里不成立。
③ 防 AI 犯错 —— A 给出一个 agent 能自己判的谓词(这条分支有没有别人在推)。⚠️ 但它也是 A 唯一的弱点:多 agent 环境里「独占」并不总是可判,判错的后果是清掉别人的工作——响亮失败与静默失败的分界就在这里,值得维护者特别称量。B 最危险:它让一个带卡片编号的提交能进 main,而且没有人会看见。C 最响亮但最贵。
④ 创业阶段不扩散 —— A 是对现有一行规则的一次收窄,不新增任何机制。B 要改门禁谓词(新机制、新失效模式)。C 新增一条永久仪式,压在每一次犯错上。

裁后执行

裁 A ⇒ 一张 pm:queue 卡给 skills 车道:改 AGENTS.md:470 一行,把禁令收窄到共享分支并写死可机械判定的判据;⛔ 不动门禁。governed 面 ⇒ 走终局四件套(draft PR + 维护者速读 + 请审两个授权账户 + 人工合并)。
裁 B ⇒ 同上一张卡,但改 scripts/check-partof-closing-keyword.mjs 的谓词,且必须在 PR 正文引用你的裁决原话(门禁削弱需明确字句)。
裁 C ⇒ 同上一张卡,把逃生路写进 AGENTS.md §3 的正文,⛔ 不留口头约定。

① 项目长远合理性:A 让成文规则、它自己的理由与实际做法三者对齐(缩小特例);B 削弱一道刻意造宽的门(增生 + 长期代价最高);C 保留互锁的两条规矩再加一层仪式。
② 实际业务拉动:实测存在——PR fix(spec): list the five service-ai-studio tools the AI tool registry was omitting #16844 已撞上并靠改写提交解决,今天的状态是规矩被静默违反,而不是被遵守。
③ 防 AI 犯错:A 给 agent 一个可自判的谓词(分支是否独占),但判错会清掉别人的工作——建议把判据机械化;B 让带卡片编号的提交能静默进 main,最危险;C 最响亮也最贵。
④ 创业阶段不扩散:A 是一行收窄、零新机制;B 新增门禁谓词与失效模式;C 新增一条压在每次犯错上的永久仪式。

	做什么	客户看到的结果	已测事实
A	把 §3 收窄到它自己的理由上：禁止在共享分支 force-push；作者独占的 `claude/*` 功能分支允许，并写死机械判据	规则与理由、与实践一致；风险是「独占」判错清掉别人的工作	判据可机械化：分支名 `claude/issue-*`、本 worktree 创建、无他人推送、无 reviewer/approval 的 PR、`--force-with-lease` 钉到自己最后推的 sha

Patch round 1 on PR #17398 (skills seat, session session_01YKEjmbYNvYWJvWGSWx26zK, 2026-09-10T11:19Z): the dev's open question is answered A minus the gate file — (1) .claude/agents/os-dev.md :68, the unconditional force-push twin the dev measured, is rewritten in place net-zero to defer to AGENTS.md §3; (2) RULE 2 of check:partof-closing-keyword is named in the dispatch template (references/dispatch-runbook.md, one line rewritten in place, net-zero) — ⛔ not by editing scripts/check-partof-closing-keyword.mjs (a devx-lane gate whose citation pin on os-dev.md :283 stays untouched). Reviewed and accepted as they stand on head 17fa9213: §3's rewrite (8 lines, widest 90 B: shared-branch ban, rationale kept, the five criteria with --force-with-lease=<branch>:<sha> and 「never bare --force」) and the ratchet ceiling 1068 → 1074 with the ruling quoted in the map's own ledger form. Resumed via SendMessage; the final head gets the ACCEPT and the governed four-piece.

ACCEPT — PR #17398 (final head a73fac30) reviewed in-seat at the contract-review tier (skills seat, session session_01YKEjmbYNvYWJvWGSWx26zK, 2026-09-10T11:40Z).

Implemented-by: os-dev subagent on branch claude/issue-16851-force-push-shared-branch (claim 5617298586; build tier claude-fable-5-1 passed explicitly; mode:subagent; patch round 1 5617834577). Reviewed-by: session_01YKEjmbYNvYWJvWGSWx26zK (the skills seat) — independence pair holds; the seat's harness reading is the tier evidence.
PR shape: draft; base main; first line Fixes #16851; skip-changeset. Changed files read from the PR: four — AGENTS.md (§3 −2/+8), scripts/pm/check-skill-line-ratchet.mjs (ceiling 1068 → 1074 with the ruling quoted in the map's ledger form), .claude/agents/os-dev.md (:68 in place), references/dispatch-runbook.md (:122 in place).
Diff vs ruling 5617189215 (option A on the maintainer's 「其他同意」): §3 reads 「Never force-push a shared branch, and never push main」, rationale kept, then the five criteria ①–⑤ exactly as ruled, --force-with-lease=<branch>:<sha you last pushed>, 「⛔ never bare --force」, 「One criterion failing ⇒ the branch is shared」; RULE 2's gate untouched (⛔ B not taken). Net +6 lines = the ruled budget; widest §3 line 90 B. Patch round: os-dev.md :68 「…推 main、合并任何东西;force-push 只按 AGENTS.md §3。」 (113 B, 403/403) — the unconditional twin that would otherwise outrank the new §3; runbook :122 names partof-closing-keyword RULE 2 and 「Fixes #<n> 只写正文」 (118 B, 241/241) — the ruling's 「派发模板里点名 RULE 2」, landed where a PM writing a dispatch reads it; os-dev.md :283 byte-identical to main (the gate's citation pin stands, check:partof-closing-keyword 95/95).
Counts on the fetched head: AGENTS.md 1074 (ceiling 1074), os-dev.md 403, runbook 241; ceiling row ['AGENTS.md', 1074] present. Dev gates at a73fac30: 43 derived families run, 43 exit 0, --ran reconciled (DERIVED zero); ratchet 157 cases; id-lint 27 clean; partof 95/95; governed-prose; nul-bytes; frame-sync; agent-model-declared; doc-authoring; check-governed-merges.mjs --test exit 3 GOVERNED (.claude/** ×2, AGENTS.md ×1); check:pm-dispatch-gates 1674 pass, exit 0 read from the redirected log. Not re-run locally by this seat (text-only diff; counts, bytes and the :283 identity re-measured on the fetched head).
CI on a73fac30 at 11:39Z: 36 check runs — 24 success, 11 skipped, 1 in progress; re-read at the next patrol before this record is cited as green.
Zone-2: A falsified (the :68 twin) and C falsified (no in-tree RULE 2 naming) — both closed by the patch round; B holds (no hook enforces the sentence); D holds (ledger comment form). Deviations accepted: RULE 2 named without the check: prefix (byte cap); the PR-body footer 第四形; the 415-then-200 label write.
Out of scope: none filed; none noted beyond the runbook naming now landed.
Terminal: governed (AGENTS.md + .claude/**) ⇒ the PR stays draft; needs-user-decision placed on PR docs(agents): scope the force-push ban to shared branches, with five unshared criteria #17398, 速读终稿 posted there, reviews requested from os-zhuang and hotlong; ⛔ not flipped ready, not enqueued, no auto-merge, no approval from this seat. On MERGED: landing record here + pm:dispatched / assignee cleared in one write with read-back; [finding] PR #16650 merged with clause-② yes and both packages it grew graded patch — the LEVEL axis could not see them, so it printed green #16973 (the changeset paragraph, same file) leaves the AGENTS.md serial.

Landed — PR #17398 merged by os-zhuang at 2026-09-10T12:05Z (merge commit cfdd0e95, final head a73fac30), governed path (AGENTS.md + .claude/** ×2 + the ratchet map): draft → human merge. This seat's ACCEPT 5618084716 is bound to that head. Verified on origin/main at 2026-09-10T12:23Z: AGENTS.md 1074 lines (ceiling 1074) with §3's shared-branch rule and five criteria; os-dev.md :68 defers to §3 (403); dispatch-runbook.md :122 names RULE 2 (241). Residue cleared in this same act: pm:dispatched off, assignee off; domain:skills, priority:p2 and the type stay. The card was closed by the merge. #16973 (the changeset paragraph, same file) leaves the AGENTS.md serial. Skills seat, session session_01YKEjmbYNvYWJvWGSWx26zK, R1.
