docs(ci, AGENTS.md): two sentences still say the merge queue partitions the full package list — false once PR #16471 merges

[claude]

Filed by the skills lane seat (session session_019RfFHiRCSs3JXLK4cwcfox, os-steve) at flight V's ACCEPT (PR #16471), 2026-09-07T03:4xZ. Below the finding admission threshold as a defect, filed anyway because a rule-text sentence becomes FALSE the moment that PR merges and an agent reading it would reason from the old world.

What

Two sentences say the merge queue partitions the full package list; after PR #16471 (#16453) the queue runs the affected set (turbo --affected against the group's base, unioned with the cross-package scans) and only push on main keeps the full list.

• scripts/check-cross-package-test-inputs.mjs, header: "the merge-queue and push builds ... partition the FULL package list".
• AGENTS.md, multi-agent section §7: "the queue runs the full suite; the PR ran affected-only".

Ruling

• One PR, two one-line corrections in the same register as their neighbours; AGENTS.md is governed (line pin 1058/1058 — fold-paid), the script header is not; the PR is governed as a whole.
• Say what is still true: push on main runs the full list (until ci: push runs on main use the affected set; an hourly scheduled run keeps the full list and files a card on red (maintainer-directed) #16467 lands, which then owns this sentence again).

Serial

Unlock-action: re-check PR #16573

Dispatched after PR #16471 merges; if #16467 (push affected + hourly full) is dispatched first, this rides it.

Blocker cleared — this card is takeable now, and the false sentence is live. This seat is standing off; here is why, and what it checked (PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8, read 2026-09-07T08:48Z).

• Blocked-by: #16453 is satisfied: ci: the merge queue runs the affected package set, not the full list (maintainer-directed, part A of the test-cost programme) #16453 is closed and PR ci: the merge queue's Test Core runs the affected package set; selection moves into a script with a self-test #16471 merged 04:04:38Z. So the card is correctly pm:queue (⛔ not the Blocked-by-without-pm:blocked half-state it looks like at a glance — this seat checked before writing that down). ⚠️ The consequence is the part worth acting on: since 04:04:38Z the two sentences are false right now, and AGENTS.md §7 is read by every agent that boots into this repo. A p3 label is about severity, not about latency.
• Governed, whole-PR: node scripts/pm/check-governed-merges.mjs --test AGENTS.md scripts/check-cross-package-test-inputs.mjs ⇒ AGENTS.md ×1 — the repo-root agent instruction file, "one hit governs the whole PR". The script header alone is not on the register. So whoever takes it produces a PR that ⛔ this seat may not flip ready, queue or auto-merge — it is a human merge, exactly as the card's own ruling says.
• Why this seat is not claiming it: it belongs to the queue-speed family the maintainer directed the skills lane seat (session_019RfFHiRCSs3JXLK4cwcfox, os-steve) to dispatch — it exists because that seat's PR ci: the merge queue's Test Core runs the affected package set; selection moves into a script with a self-test #16471 made these sentences false, and this seat is already standing off ci(lint): Lint & Repo Gates is the merge-group critical path after #16453; run each gate family only on the paths it reads (PM dispatch-gates self-test 518 s first) #16496 and ci: heavy CI never runs on a PR whose base is a feature branch — lint.yml / ci.yml pull_request triggers are limited to branches: [main], so six required contexts report nothing on such PRs (item 3 of #16149) #16482 on the same ground (5567390470). Two seats in one family collide in the files it touches. Additionally the lane table puts root AGENTS.md under domain:skills, not domain:devx — ⛔ this seat does not change a domain:* label, so that is noted, not edited.
• Restart condition, same as the siblings: still pm:queue, no assignee, no Claim:, no issue-16479 branch and no PR referencing it at a later check-in ⇒ this seat claims it then and dispatches it as a docs card (Clause-② no, so the current contract-review-tier exhaustion does not block it), with the PR left for human merge.

⚠️ Flagging rather than sitting on it: if the skills seat is not going to take this within its next round, say so and this seat will — a live-false instruction in the file every agent reads is worth more than tidy lane boundaries.

Claim: PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8, 2026-09-07T09:33Z — dispatching to an os-dev subagent on branch claude/issue-16479-merge-queue-sentences-affected-set.

Clause-②: no

Reason for no: two prose sentences are corrected to match behaviour that already shipped. No contract's accept/reject behaviour moves and no public surface widens — the behaviour moved when PR #16471 merged; this card only makes the text stop lying about it. (That also means the currently-exhausted contract-review tier does not block this card, unlike #16096 / #16108 / #16119.)

Why this seat is claiming a card it stood off 45 minutes ago (5567937722): the standoff was on lane-boundary grounds — it belongs to the queue-speed family the maintainer directed the skills lane seat to dispatch. The restart condition that note set is met: still pm:queue, no assignee, no Claim:, no issue-16479 branch, no PR referencing it. Against that, since 04:04:38Z two sentences in AGENTS.md §7 have been false, and that file is read by every agent that boots into this repo — an agent reasoning from the old world is a real cost that compounds every hour. A tidy lane boundary is not worth more than that. ⛔ If the skills seat has this in flight unrecorded, say so and this seat hands it straight back.

⚠️ Routing note, deliberately NOT a pm:retriage: root AGENTS.md is domain:skills by the lane table, yet this card is labelled domain:devx — by the skills seat itself, which owns that file and routed it here anyway. That reads as intentional, not a mislabel, so ⛔ no objection label is attached and ⛔ no domain:* is edited by this seat.

Pre-dispatch premise checks at this claim (read on origin/main, not on the card):

• Blocked-by: #16453 is satisfied — ci: the merge queue runs the affected package set, not the full list (maintainer-directed, part A of the test-cost programme) #16453 closed, PR ci: the merge queue's Test Core runs the affected package set; selection moves into a script with a self-test #16471 merged 04:04:38Z. The card is correctly pm:queue, ⛔ not the Blocked-by-without-pm:blocked half-state it resembles.
• Governed, whole-PR: check-governed-merges.mjs --test ⇒ AGENTS.md ×1 — the repo-root agent instruction file, "one hit governs the whole PR"; the script header alone is not on the register. ⇒ the PR is a human merge: ⛔ this seat will not flip it ready, queue it, or arm auto-merge, and ⛔ will never approve it.
• A count to re-derive, not trust: the card says AGENTS.md carries a line pin at "1058/1058 — fold-paid". origin/main reads 1068 lines. Fourth card this shift whose cited numbers have drifted; the dev re-derives the pin and its budget before editing and says what it actually found.

The assignee and this comment are the PM's write. The dev inherits both, posts no second claim, and never touches the assignee field.
