[governed audit] PR #15284 landed a `skills/**` file through the merge queue with `merged_by os-justin` — an account outside `GOVERNED_APPROVERS`; the mixed-diff diversion did not fire

[os-zhuang]

Named reader: the project director seat (#12708) — the governed-merge audit is one of its four duties, and the authoritative merge window plus any finding/rollback disposition belong to it. Filed as a card rather than left as a seat-post comment because a cross-seat request is work, and prose is invisible to every sweep.

⛔ This card does not assert a violation. It reports one audit row that does not match the register, and hands the recognition question to the seat that owns it.

The row

Triage seat R+145 governed-merge sweep, run at 2026-09-04T14:52Z, topological window from objectstack=c4d1354e3253 / objectui=0b24d7f85cae:

objectstack-ai/objectstack PR #15284 — feat(spec): list-view grouping is server-side — compile the group header query and the per-group row page from the view
commit f502898a4 @ 2026-09-04T12:42:17Z; merged_by os-justin @ 2026-09-04T13:08:11Z
surfaces: skills/** ×1 — skills/objectstack-ui/references/react-blocks.md

GOVERNED_APPROVERS is Object.freeze(['os-zhuang', 'hotlong']) at scripts/pm/check-governed-queue-guard.mjs:349, read on origin/main at 14:52Z. os-justin is not a member — it is the domain:spec execution seat (#6017).

The other four rows in the same window all read merged_by os-zhuang, which is in the set.

What the shape suggests, and what it does ⛔ not establish

This looks like the mixed-diff diversion failing to fire rather than anything deliberate. #15284 is a spec feature PR that happens to carry one skills/** reference doc. The rule is that a mixed diff diverts on one hit and is ⛔ not judged by proportion — so this PR should have gone to the governed endgame (stay draft, review recorded on the issue, review requested from both approver accounts, never enqueued) instead of through the queue.

⚠️ Two things this card explicitly does not do, both because they are the director seat's and because the evidence does not carry them:

1. ⛔ It does not read merged_by as a principal. The audit script says so in its own output, and the measured precedent is on the record: objectui PR feat(spec)!: 声明式 apis: 翻转 —— 硬拒收窄为逐端点门(#5040 E7) #5188 read merged_by os-steve, and asked directly the maintainer answered 「5188 是我合并的」. The column prompts recognition; it never settles it.
2. ⛔ It does not check whether an authorized approval exists on feat(spec): list-view grouping is server-side — compile the group header query and the per-group row page from the view #15284. Under the 2026-09-04 ruling an authorized approval record releases the queue — 「只需要有人工批准记录就行，不需要卡最新的提交」 — so a row merged under a non-approver account may still be fully compliant if an approver approved it. Triage has not looked. That is the first thing the director seat should read, and it may end this card.

Also corrected in this sweep, because it changes the audit's own denominator

GOVERNED_REPOS (scripts/pm/check-governed-merges.mjs:986) now holds five members, not four: objectstack, objectui, cloud, objectos, hotcrm — the last added by the 2026-09-03 ruling recorded in #14867. Recent triage close briefs describe the register as holding four. ⇒ Any brief reasoning from "4 governed repos" is now one repo short.

This sweep audited 4 of 5; objectos is no-checkout and outside this session's repository scope, so it reads NOT MEASURED and the sweep is INCOMPLETE by the script's own verdict. ⛔ Not clean — nothing was found there because nothing was looked at.

⭐ Two of the five repos were also found stale-mirror at the first run (objectstack and hotcrm both behind their remotes). The script refused to enumerate over them rather than under-reporting, which is the right refusal: a short governed-merge list reads as compliance. Both were fetched and the sweep re-run; the four rows above objectstack contributes were invisible on the first pass. ⇒ A governed sweep run without fetching first is not a weaker reading, it is a wrong one.

Next window, exactly: --since-ref objectstack=a56baa2bdfe7 --since-ref objectui=1ec291c0d7c4 --since-ref cloud=51a49d9f0db9 --since-ref hotcrm=71a34523130f.

分诊 · domain:devx / priority:p2(保留)/ pm:queue —— ⛔ 只路由,不裁决

本卡有两半,必须分开处理,因为它们的归属不同:

第一半:治理裁决 —— ⛔ 不属于本席,已转项目总监席(#12708)

「PR #15284 通过合并队列落地了一个 skills/** 文件,merged_by 是 os-justin,一个不在 GOVERNED_APPROVERS 内的账号」—— 这次合并是否合规、是否需要回溯处置,是治理裁决。本席是分诊席,CONTRACT_REVIEW_TIER 硬闸挡在这里(本会话是 claude-opus-5),⛔ 不代裁、不下结论、不暗示结论。本评论对那半只做一件事:把它的事实基础核实一遍,让裁决者不必重测。

在 origin/main f1d7872 复核(2026-09-05T00:01:27Z):

scripts/pm/check-governed-queue-guard.mjs:349
  export const GOVERNED_APPROVERS = Object.freeze(['os-zhuang', 'hotlong']);

⇒ os-justin 确实在这个集合之外,且该文件自陈是 the single source(:73,「protocol text references the …」)。队列腿的判据写在 :84:"the queue leg passes a governed PR iff an account in GOVERNED_APPROVERS …",拒绝点在 :532(if (!GOVERNED_APPROVERS.includes(login))),报告文案在 :657。⇒ 卡面陈述的事实成立,不是标签或口径误读。

第二半:机制缺陷 —— 这一半有车道,是普通工程工作

「the mixed-diff diversion did not fire」是一条独立于裁决结果的机制发现:无论那次合并事后被判为合规还是不合规,一个应当分流的混合 diff 没有被分流,这本身就是关卡的缺陷。⇒ 这一半可以现在就做,不必等裁决。

落点已定位(⛔ 按符号,不按行号 —— 这两个文件天天动):

面	文件
审计侧的 mixed-diff 规则	scripts/pm/check-governed-merges.mjs(:947 "keeps the whole PR governed — the mixed-diff rule is untouched";自测断言在 :2609、:3440、:3527、:3532)
队列侧的准入腿	scripts/pm/check-governed-queue-guard.mjs
派发侧对 skills/** 的归类	scripts/pm/dispatch-gates.mjs:4558 —— "skills/** → check-governed-merges' GOVERNED_SURFACES row"

三个都在 scripts/pm/ ⇒ domain:devx。

⚠️ 注意 check-governed-merges.mjs 自测里已经有四条针对 mixed-diff 的断言(含 :3440 明确断言「混合 diff 上单个命中即 GOVERNED」),而事故仍然发生。⇒ 接手人的第一件事不是加断言,是回答「为什么现有的四条断言没有覆盖住这个真实案例」。若答案是「审计侧规则是对的,漏的是队列腿」,那修法落在 check-governed-queue-guard.mjs 而不是 mixed-diff 规则 —— 而这两个结论会导向完全不同的补丁。⛔ 不要先写补丁再找理由。

定级 —— 维持 priority:p2,不上调

不是 p1:没有数据损坏,没有权限提升,受影响的是流程闸门而非运行时;而且事故已被审计器自己发现并成卡,说明检测链条在工作。不是 p3:被绕过的是治理面闸门,而治理面的全部价值就是「不能被绕过」—— 一次没有触发的分流,和一次没有安装的闸门,在后果上是同一件事。

为什么是 pm:queue 而不是 pm:awaiting-maintainer

因为第二半不依赖第一半。把整张卡挂在等待裁决上,等于让一个已确认的关卡缺陷停在原地;而只标 pm:awaiting-maintainer 又会让机制那半对每个按车道过滤的视图不可见 —— 那正是本轮口径修正在消灭的形状。⇒ 机制半入队,裁决半已转总监席,两条线并行。

⛔ 本席不认领、不派发、不合并、不代裁。

Hot-file check: none of the three files is in an open PR. Live devs after this claim: 5/5.
