pm-dispatch enqueue: merge main first when the last green PR run is 15+ merges behind, and no re-enqueue on an unchanged head after a deterministic red

domain:devx#2 · zhuangjianguo · session_01QsR2jTo666XXx9e1Gm21C6

Filing gate: ③ a task the maintainer directed. This is the enqueue-procedure half of #31518. The maintainer's words on that card, verbatim: 「同意，立卡」 · 「高优先」 (2026-11-08T12:30Z). #31518 itself routes this half here: "Any change to the enqueue procedure (.claude/skills/pm-dispatch/**, the fleet-write relay) is domain:skills' and governed; the devx seat files it there with the readings." ⛔ Not a claim. No grade: triage sets it.

Business reason. Every PR author waits in the merge queue. In 2026-11-01..07, stale-base entries were 21 of 68 queue roots and caused 122 of 157 cascade rebuilds: each one is a PR that was green on its own run, entered the queue far behind main, went red there and ejected the entries behind it (5.8 cascades per root). A further 28 cascades (18% of the window) came from 5 PRs re-enqueued with an unchanged head after a deterministic red. Multi-build PRs waited p50 48 min and p90 130 min against 18 min for one build (#31518 "Business reason").

Reader who acts. The domain:skills seat, on .claude/skills/pm-dispatch/references/landing-operations.md (the enqueue rules) and, if a rule should be enforced and not only written, the relay's automerge_enable / enqueue op under scripts/pm/fleet-write/. Governed (Tier S / relay); no CI or workflow change.

Measured (#31518 step 1, comment 6722460022, roots table with 68 rows)

K = git rev-list --count --first-parent PRBASE..origin/main, where PRBASE is the diff base of the PR's last green run (Test Core's Affected-set diff base line). Every (a) root with a measured K had K ≥ 7 (median 25).
Refresh threshold, as measured over the window:

refresh when K is at least (a) roots caught (a) cascades caught other rows also refreshed

10 19 of 21 116 of 122 21 of 47

15 16 of 21 108 of 122 12 of 47

20 13 of 21 82 of 122 10 of 47
Re-enqueued with an unchanged head: 12 roots. 5 were deterministic reds that went red again (fix(scripts,objectql): codemod-split-engine --members reads hand-written facet headers and inverts its import edits; move registerApp, registerDriver and registerHook #30716, docs(skills): the automation skill teaches the mail option formatter for a notice's select label and the active-member rule for a user target; the docs page gains organization-authored assignment rules #30866, feat(i18n)!: the Console's language packs follow the platform locale table, keyed by its tags, and Traditional Chinese (zh-Hant) ships #30902 twice, i18n(platform-objects): ship the platform objects, Setup, Studio and Account in French #31233), costing 28 cascades. The other 7 were flakes, and retrying those was correct. AGENTS.md §7 already says "a stale red clears only with a new commit (git merge origin/main), never by re-running"; the rule exists and was not followed at enqueue.
A PR run that starts after a landing has not necessarily seen it: feat(i18n)!: the Console's language packs follow the platform locale table, keyed by its tags, and Traditional Chinese (zh-Hant) ships #30902's last PR run was created at 15:08Z, after ci(test-source-alias): follow a changed test into the source it loads, and red a cold literal import() paid there #30969 landed at 14:55:57Z, and still tested a 14:13Z base. So the rule keys on the run's diff base, not on its start time.

Wanted

Before arming auto-merge or enqueuing, the seat reads K for the PR's last green run; at K ≥ 15 it merges origin/main and waits for a green re-run first. The devx reading recommends 15: one extra PR CI round on about a quarter of entries, against 108 of 122 cascades. docs(pm-dispatch): merge main before landing a label PR when a new locale landed under it #31536 (merged) is the locale-label special case of this rule and is subsumed by it or kept beside it; the skills seat decides.
A PR the queue ejected is not re-enqueued until its head changes or the ejection is read as a flake (same tree green on re-run, or a queue-flake anchor names the test).
⛔ No gate skipped or made report-only, no required context dropped, no merge-queue setting changed (ci(merge-queue): one bad entry turned into ~6 red rebuilds on 2026-11-06 (18 roots, 110 cascades) — find why each root was green on its PR, and stop the classes the enqueue step can catch #31518 Wanted 3).

Acceptance

The rule text is in the landing procedure; if the relay enforces it, its self-test pins K 14 (passes) / K 15 (refused without a merge) and unchanged-head-after-red (refused).
ci(merge-queue): one bad entry turned into ~6 red rebuilds on 2026-11-06 (18 roots, 110 cascades) — find why each root was green on its PR, and stop the classes the enqueue step can catch #31518's 7-day re-reading counts it: stale-base roots per week.

⛔ Not a claim.

Grade: p1. This is the enqueue-procedure half of ci(merge-queue): one bad entry turned into ~6 red rebuilds on 2026-11-06 (18 roots, 110 cascades) — find why each root was green on its PR, and stop the classes the enqueue step can catch #31518, which the maintainer marked 「高优先」.
Lane: domain:skills is right: references/landing-operations.md, and the relay's enqueue op only if the rule is enforced rather than written. Governed Tier S.
Same root class as Queue: the two translation-bundle lint gates red only in the merge queue, so a PR that declares an untranslated label passes its own CI and ejects its stack (6 ejections on 2026-11-08) #31512. That card's landing rule (stale base against new locale bundles) landed in PR docs(pm-dispatch): merge main before landing a label PR when a new locale landed under it #31536 at 13:59Z. The K-threshold rule here generalises it, so it should be written as one rule in the same place, with docs(pm-dispatch): merge main before landing a label PR when a new locale landed under it #31536's text folded into it rather than kept as a sibling.
On enforcement: a written rule is the default (「新增门禁默认否」). Making the relay refuse to enqueue is a new gate and needs a decision card first.

Thread-read: 6723002344
Premise: holds. On main 8c75f837 landing-operations.md (102 lines) carries only the locale-label refresh at L33–34 (#31536). No rule reads K, the first-parent count from the last green run's diff base, before enqueue. The written rule is the deliverable; relay enforcement is out (a new gate needs a decision card first, per triage).
Serial constraints cleared: none on this file. Card #31403 (queue jump, held on a decision) also concerns enqueue but has no open PR.

Dispatch order: pasted verbatim into the card thread's opening message (common rules + order, from the seat folder skills-seat-2/ of the project files). Writes: PR only via relay pr_create; comments, labels and bodies only via scripts/pm write tools; no GitHub MCP writes.

Landed · 2026-11-08T16:11Z — PR #31571 merged through the merge queue (merge commit 87df07b). It landed on the director's CONTRACT_REVIEW_TIER PASS 6723543881 for head f4544c2.

landing-operations.md now has the pre-enqueue K rule:

K counts first-parent commits from PRBASE to origin/main. PRBASE is the diff base that the last green run's Test Core prints.
At K ≥ 15, merge main and wait for green before arming or enqueueing.
The docs(pm-dispatch): merge main before landing a label PR when a new locale landed under it #31536 locale-label case refreshes at any K.

The four-branch opener now says that with an unchanged head, a PR is re-enqueued only on a flake reading. Relay enforcement of the K rule was not built: it is a new gate and would need a decision card first.

pm:dispatched removed. Nothing left on this card.
