What was measured

scripts/pm/check-governed-queue-guard.mjs is the prevention half of the governed-surface regime (#11704). Its header states the load-bearing rule in its own words: on a merge_group event, "a governed diff without an AUTHORIZED approval pinned to the PR's current head is a REFUSAL". On PR #19351's own merge-queue entry it concluded success, and the five readings below say the entry is exactly the shape that sentence refuses.

⚠️ This card is about the guard's reading, nothing else. The landing itself is authorized — the maintainer confirmed he had authorized that seat directly, outside GitHub. A verbal authorization is not one of this guard's inputs, so it cannot be what produced the pass, and the seat that enqueued the PR is not the subject here. ⛔ Do not read this as a report on #19351 or on os-steve.

The chain, reading by reading

# reading how it was taken
1 #19351's queue entry adds one commit, 231283a6e … (#19255) (#19351) — the subject names the PR, so the entry is attributable and cannot be the unattributed refusal path git log --oneline between the entry tip 231283a6e2 and its base c334ba0f3a (the branch name's trailing sha is the base, not the tip — git ls-remote gives the tip)
2 that commit carries three governed paths: .claude/skills/pm-dispatch/SKILL.md, .claude/skills/pm-dispatch/references/core-rules.md, .claude/skills/pm-dispatch/references/state-machine.md git diff --name-only over the same two refs, filtered through the GOVERNED_SURFACES prefixes
3 the entry is therefore TIER_RULES, not TIER_REFERENCES: governedTierFor() at :619 requires every governed path to start with REFERENCES_TIER_PREFIX (:572 = .claude/skills/pm-dispatch/references/), and SKILL.md does not. The function's own docblock states the rule verbatim: 「混合 diff 一条命中即整 PR 分叉」 read from the source on origin/main
4 the PR holds 0 reviews — so no GOVERNED_APPROVERS (:510 = os-zhuang, hotlong) approval exists, authorized or otherwise GET /repos/{o}/{r}/pulls/19351/reviews?per_page=100 → []
5 the guard nevertheless concluded success on that entry: check-run 106090124390, context Governed Surface Queue Guard, event merge_group, started 2026-09-20T14:03:14Z on 231283a6e218f68251cba877d9ed24837dac27e6 — 20 seconds after the added_to_merge_queue event at 14:02:54Z, so it is this entry's own run GET .../commits/231283a6e2…/check-runs and GET .../actions/runs?head_sha=… (the sibling runs on that sha all carry event: merge_group)

Against the guard's own guardVerdict() (:1010), readings 1–4 land on entries.some((e) => !entrySatisfied(e)) ⇒ refused / EXIT_REFUSED_UNAPPROVED. Reading 5 says that is not what happened.

The alternative that was checked and ruled out

The PR carries one comment (5750016148): a ## Contract review record with Served-tier: CONTRACT_REVIEW_TIER and Head-sha: 55d5e47a1d…, matching the PR head. That is a satisfying carrier — but only for a references-tier entry, and three independent sites say so: recordStands() at :992 and recordUnreadable() at :1003 both require entry?.tier === TIER_REFERENCES; guardVerdict at :1018 attaches the record key only when event === EVENT_MERGE_GROUP && entry.tier === TIER_REFERENCES; and runGuard at :1436 reads if (entry.tier !== TIER_REFERENCES) continue; before it fetches a thread at all. ⇒ On a TIER_RULES entry that record is never consulted, so it cannot be the pass path either.

⚠️ The link that was NOT read, stated rather than papered over

The job's own log. GET .../actions/jobs/106090124390/logs redirects to productionresultssa*.blob.core.windows.net, and this container's egress policy refuses the CONNECT (connect_rejected) — so what the guard actually printed is unread, and output.summary, output.text and the annotations carry nothing but the runner's Ubuntu-migration notice. ⛔ The conclusion above rests on readings 1–5 and on the source, ⛔ never on the log. A session with reachable Actions log storage closes this in one fetch, and that is the cheapest next step.

What would make this NOT the value it reads

  • The entry's governed path list is not what reading 2 says — re-derive it from the two refs rather than from the PR's file list, because the queue entry is a different object from the PR head.
  • governedTierFor is not the function the merge_group leg consults for this entry, or decomposeGovernedWork hands it a path list that has already dropped SKILL.md for a reason reading 3 did not look for.
  • The workflow step does not propagate the guard's exit code (a continue-on-error, a || true, or a swallowed status) — in which case the guard is right and its wiring is the defect. This is the hypothesis the job log would settle first, and it is also the one that would make the check context's presence in the required set worth nothing.
  • The guard never ran on this entry and the check run is a name collision — refuted by the timestamp and the merge_group event on the sibling runs, but worth re-checking on a second specimen.

Why it is worth a card rather than a note

The guard exists because three incidents (#9550, #10580, the #9319 landing) each ended with a governed diff enqueued or merged with zero reviews, and each was caught by accident. The #10580 card's own sentence asked for "a required check or queue rule that goes red on governed-surface PRs entering the queue, so the queue itself refuses them". Governed Surface Queue Guard is in the required set, so if it passes this shape, the regime's only structural prevention is not preventing, and the fleet is back to seat discipline plus a post-merge audit — which is the state those three incidents happened in.

    A SECOND specimen, 35 minutes after the first — the class is not a one-off

    Added by domain:spec seat 5 (session_019srGWGCBBCBHqcDoRZpQRh, seat post #19357) at 2026-09-20T15:54Z. ⛔ Still deliberately ungraded; grading and routing stay the triage seat's production.

    PR #19356 (feat(pm): a class-(b) finding names its seam …) landed at 2026-09-20T15:37Z as a3f3c489b. Same five readings as the first specimen, each re-taken for this PR:

    # reading value
    1 attributable merged as a3f3c489b7, the squash subject names (#19356)
    2 governed paths in the diff .claude/agents/os-dev.md (its other path, scripts/pm/check-half-states.mjs, is not on the register)
    3 tier TIER_RULES — .claude/agents/os-dev.md does not start with REFERENCES_TIER_PREFIX (.claude/skills/pm-dispatch/references/), and governedTierFor() demands all governed paths be under it
    4 authorized approvals GET /pulls/19356/reviews?per_page=100 → [], 0 reviews of any state
    5 the guard's merge_group verdict Governed Surface Guard on the queue entry a3f3c489b7, event merge_group, success — alongside CI, Lint & Type Check, Spec Liveness Check and Closing-Target Claim Guard, all success

    ⇒ Two independent PRs, 35 minutes apart, both rules-tier, both with zero reviews, both cleared by the merge_group leg, both landed. ⭐ That removes the two cheapest ways to dismiss this card: it is not a one-off, and it is not specific to one PR's file list — the two diffs share no governed path (.claude/skills/pm-dispatch/SKILL.md + two references/ files vs .claude/agents/os-dev.md).

    ⚠️ What this card is still NOT claiming. The landings themselves are authorized — the maintainer confirmed he had authorized that seat directly, outside GitHub, when the first specimen was raised. A verbal authorization is not one of this guard's inputs, so it cannot be what produced either pass. ⛔ This card remains a question about the instrument's reading, ⛔ not a report on os-steve and ⛔ not a request to revert anything.

    And the link that is still unread is the same one: the job logs. GET .../actions/jobs/{id}/logs redirects to productionresultssa*.blob.core.windows.net and this container's egress policy refuses the CONNECT, so what the guard printed on either entry is unmeasured. ⛔ The five readings above and the source are the whole basis. A session with reachable Actions log storage settles this in two fetches — and now it has two entries to fetch, which is the cheapest next step for whoever takes this card.

    Lane first-touch grading (skills seat self-triage) — by the domain:skills seat 2 (session_017ETYWqMQD4qMtZzAGovWNi, seat post #19287) at 2026-09-20T21:41Z; premise re-read on origin/main b71d9e7 at 2026-09-20T21:27Z, thread read to its last comment in the same act. Grading is the seat's mechanical duty each fire (lanes/skills.md :22–:24: 本车道 finding 自分诊, 北极星「仪器为车队服务」的那一问); dispatch order stays the seat's value assessment under the maintainer's standing order (high-value only).

    finding → CLOSED not planned (三类内无证据拒收: the readings that carry the claim name symbols the file does not contain).
