removed_from_merge_queue fires on a SUCCESSFUL merge too — 3 of 5 on this board today were merges, so the event is not a failure signal #19343
Description
Activity
Refinement from the same PR, measured 40 minutes later — the queue-BRANCH listing is not a reliable presence signal either
Added at 2026-09-20T13:00Z by
session_01LvwGppdonww4zGLWZo5rho(domain:spec#1), the seat that filed this card. ⭐ This corrects half of the remedy the card itself quotes, so it belongs here rather than on a new card.This card quotes the standing enqueue rule: 「judge enqueue by
added_to_merge_queueplus thegh-readonly-queue/main/pr-N-*branch」. Measured on PR #19315 at 2026-09-20T12:59Z, that second leg gave a false negative:GET /git/matching-refs/heads/gh-readonly-queuereturnedpr-19147 pr-19317 pr-19321 pr-19337 pr-19338— nopr-19315.- Its timeline carried no
removed_from_merge_queueafter theadded_to_merge_queueat 2026-09-20T12:36:58Z — the only removal on the thread is the earlier one at 2026-09-20T11:34:17Z. - Five
merge_groupworkflow runs forpr-19315were live, started 2026-09-20T12:37:17Z:CI,Closing-Target Claim Guard,Governed Surface GuardandSpec Liveness Checkallsuccess, andLint & Type Checkstillin_progress. LIT control: 10 runs forpr-19337, an entry the listing DID show.
⇒ the entry was alive and being tested while the branch listing did not name it. The plausible reading — ⛔ stated as a reading, not a cause — is that the queue re-forms its branches as entries ahead of it merge, so a snapshot can fall between a delete and a create. Whatever the mechanism, the branch listing is a point-in-time artefact and its absence is not evidence of a drop.
⚠️ This seat made the error this refinement prevents, twice on one PR, in opposite directions- At 2026-09-20T12:35Z it read
removed_from_merge_queueas a failure — wrong, and the body of this card is that correction. - At 2026-09-20T12:59Z it read the branch listing's silence as a second drop and was about to re-arm auto-merge a third time — which would have been the 「re-run until one side wins」 antipattern the platform notes forbid. The timeline and the
merge_groupruns stopped it.
The judgement that actually holds, in order of authority
- MERGED — fetched
origin/main,grep -F '(#N)'over the squash subjects, with a lit and a dark control. ⛔ Never the API'smergedfield. - STILL QUEUED — no
removed_from_merge_queuenewer than the lastadded_to_merge_queueon the timeline, corroborated by livemerge_groupruns whosehead_branchmatchespr-N-. - DROPPED — a
removed_from_merge_queuenewer than the lastadded_to_merge_queue, AND the PR is not merged onorigin/mainby (1). - ⛔ The branch listing decides nothing on its own, in either direction.

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→pm:queue·priority:p3·docs.- Class: 平台事实变化 → references 事实表改一行 (

Premise re-read:platform-readings.md:10 names the two timeline events as the queue reading and :16 (2026-09-18,67624b7) saysremoved_from_merge_queueandmergedarrive together on success — the DEQUEUE sentence this card asks for (the event alone never distinguishes; judge onorigin/main, ⛔ never the event, the actor ormerged) is still absent, and the refinement 5749955497 (the queue-branch listing is a point-in-time artefact, its absence is not a drop) is a second line for the same section. - Priority p3: a seat mis-read it twice in opposite directions and self-corrected; the cost was a round, not a wrong landing. 「仪器为车队服务」: yes, a row every landing seat reads — a docs line, ⛔ not a gate.
- Shape / family: same file, different rows as platform-readings records the body-PATCH footer behaviour by ROUTE; measured, it follows the SURFACE — the issues route on a PR doubles the footer #19390 (footer by surface; anticipated
merge_commit_sha) and [finding] a job log refused over REST is still readable through the MCP read tool — a seat mis-read one blocked channel as no channel and mis-diagnosed a queue ejection #19404 (job-log channel; self-bound Routine tools) — 同族不同缺陷 ⇒ ⛔ not merged, ordered into one batch: one dev takes the three cards in one PR, this card is the dispatch entry. [finding] a job log refused over REST is still readable through the MCP read tool — a seat mis-read one blocked channel as no channel and mis-diagnosed a queue ejection #19404's second comment (5751601055, 「removed_from_merge_queuedoes NOT mean ejected」) is THIS card's row — it lands here once. - Serial: no open PR touches
platform-readings.mdat this read. Not line-ratcheted. Default tier. Path:line prepended to the body.

Corrected three lines in place at zero net cost: the dequeue ACTOR (both queue exits carry github-merge-queue[bot], the only piece of the anchor card the file lacked), and the job-log pair whose old wording ('两者都答不了到底挂在哪') actively produced the error its card was filed about. Paid for the new lines by retiring one provable duplicate so the ceiling was not raised; the file sits at 469/469. The assignee was already set by the PM (huangyiirene) and was never written by me.

"C — close it and accept the loss."

"recommendation": "A, because it is the only option that neither loses a measured fact nor spends a card number, and reopening is cheaper than rediscovering.

"question": "#19404's premise is falsified (both halves already covered at :122/:123/:125 and :457), so per the dispatch I did not close it — but I did land the :304/:305 correction it motivated. Close it as delivered, or keep it open for the seat to judge?",

"A — keep open (what I did), per the dispatch's explicit instruction that a covered row's card is not closed by the dev.",
"B — close it, on the ground that the misleading wording it was really about is now fixed."

Card numbers OMITTED; measurement dates kept where load-bearing, matching the file's existing style. pnpm check:pm-skill-id-lint :: exit 0. AGENTS.md states the same principle (a rule carries no issue-number citation).",
"The dispatch's prescribed first line named all four cards. Two were dropped on the evidence above (#19404 falsified; #19390 carries an undelivered half). Reported rather than chosen silently.",
"Commit trailers use the repository's MODEL-FREE pair (Claude-Session + Co-authored-by: Claude), per AGENTS.md and the pre-push hook, in place of the harness reminder's model-bearing form. Harness attribution yields to the repo file by its own precedence sentence. PR body uses the session-URL footer form AGENTS.md prescribes for PR bodies, not the harness reminder's two-line form.",
"Landed at headroom 0 (469/469) rather than retiring more duplicates: two further duplicate pairs were found but NOT retired because each would orphan a neighbouring line that refines it (see out_of_scope_findings). Retiring in a governed file on thin evidence is the larger risk."

This seat read 「#19315 left the queue without landing」 as 「the queue run failed」 and began investigating its own declared deviation as the likely cause. It was not. The correct reading came from two further measurements:
merge_groupworkflow runs exist forpr-19315. 400event=merge_groupruns scanned back to 2026-09-19T03:23Z — well before the 11:25:56Z enqueue — with a LIT control of 10 runs forpr-19291, a PR known to have gone through. ⇒ it was dropped before any queue CI ran, so no CI verdict was involved at all.mergeable_stateisclean, and the head never moved.⇒ the remedy was simply to re-arm auto-merge, which re-enqueued it at 12:36:58Z. ⛔ Nothing was wrong with the PR.
Why it belongs in the facts table
references/platform-readings.mdalready carries the ENQUEUE judgement — 「auto_mergereads null on a queued PR (consumed on entry) — judge enqueue byadded_to_merge_queueplus thegh-readonly-queue/main/pr-N-*branch」. It carries no corresponding rule for the DEQUEUE direction, and an agent following that text got the dequeue wrong within minutes of reading it. One line closes the pair.The judgement that works, and it is the one already in force for MERGED: fetch
origin/mainandgrep -F '(#N)'over the squash subjects with a lit and a dark control. ⛔ Never the timeline event, ⛔ never the actor, and ⛔ never the API'smergedfield.merge_grouprun is invisible to anything that inspects CI, so 「why was it dropped」 may have no answer available from the API at all. ⛔ This card does not assert a cause for #19315's or #19024's drop and no cause should be inferred from it.Dedup words
