[finding] `AGENTS.md` §7 still names TWO classes of PR that never land on green alone — the maintainer's 5,000-changed-lines class (#19012) is the third, and the rules layer contradicts the landing rule until it says so

[os-elon-musk]

Filed by the domain:skills execution seat (session_01BTeBejoPUvRHN8WdAJC6oF, seat post #7623) at 2026-09-18T12:52Z, from the #19012 dev's out_of_scope_findings on PR #19033 (report 5730187995), the class decided by the seat as the dev asked. Labels domain:skills · pm:queue set by the seat (its own lane: scripts/pm/** / governed text); priority left to triage.

Dedupe words: AGENTS.md green alone third class · 5000 lines human merge AGENTS · two classes of PR never enter on green alone · size class rules layer. Dedupe reading: the shift's corpus and every card since — none names §7's two-class sentence.

Class (b) — the rules layer names two classes where the maintainer ruled three

AGENTS.md §7, verbatim shape: 「Two classes of PR never enter this path on green alone」 — the governed surface and Version Packages. The maintainer's 2026-09-18 ruling (verbatim 「还有应该完善skills，修改代码量超过某个行数（比如5000）就应该人工审核。」, recorded on #16045 and carried by #19012 / PR #19033) adds a third: a PR over 5,000 changed lines (additions + deletions, generated files included). SKILL.md :608 and references/landing-operations.md :26 now say so; AGENTS.md still says two, so the rules layer contradicts the landing rule until one line is added there. Governed text (AGENTS.md, 1099 / 1099 — fold or pay).

What is asked (⛔ not asserted — triage grades)

One line in §7 naming the third class with the number and the 「generated files included」 clause, in the section's register; net 0 at the ceiling. Refs: #19012 / PR #19033; SKILL.md :608.

Lane first-touch grading (skills seat, session_01BTeBejoPUvRHN8WdAJC6oF) · 2026-09-18T13:07Z — the skills lane grades its own findings (lanes/skills.md).

• Class (b): AGENTS.md §7 names two classes of PR that never land on green alone; the maintainer's 2026-09-18 ruling ([ruling] a PR whose changed line count exceeds 5,000 lands only by a human merge — rule line in SKILL.md + landing-operations.md, and a size predicate in the landing gate #19012 / PR feat(pm): a PR over 5,000 changed lines lands only by a human merge — size predicate in check-governed-merges --test, the same reading in dispatch-gates, one rule line in SKILL.md and landing-operations #19033) makes three, and the rules layer contradicts the landing rule until the line is there.
• Type Task · priority:p2 · pm:queue. p2: a governed-text contradiction with no incident yet (the mechanical face is PR feat(pm): a PR over 5,000 changed lines lands only by a human merge — size predicate in check-governed-merges --test, the same reading in dispatch-gates, one rule line in SKILL.md and landing-operations #19033's; this is the human-read half). Governed (AGENTS.md, 1099 / 1099 — fold or pay) ⇒ CONTRACT_REVIEW_TIER, the four-piece terminal. Dispatchable now: no open PR touches AGENTS.md (PR docs(agents): give the claim pre-check its right delimiter, so a card number cannot prefix-match #18918 merged at 11:47Z). Deliverable: one §7 line naming the third class with the number and 「generated files included」, net 0.

ACCEPT — PR #19042 @ 8454706591 (one commit; one file, +6 / −6) · skills seat session_01BTeBejoPUvRHN8WdAJC6oF · 2026-09-18T13:47Z

Read on GitHub: draft, base main, body line 1 Fixes #19037, Clause-②: no at line start; closing keywords touch this card only; get_files = AGENTS.md; skip-changeset present (size/s, documentation are the labellers'); report 5730878764 names the head, literal first line os-dev-report, no HTML comment, read back to the tail; the body carries ## 维护者速读(草稿). Gates: 14 derived / 14 run / 0 NOT-MEASURED at 845470659; check:pm-dispatch-gates 1849 cases (detached, verdict line read). Seat re-measure on a scratch worktree at the head: 1099 / 1099 (ratchet ✓, headroom 0; row pin 768 ✓), id-lint ✓ 27 files (0 citations in AGENTS.md), every changed line ≤ 117 B, --pair 19042 exit 0, closingKeywordTargets = {19037 → Fixes}, check-governed-merges.mjs --pr 19042 → GOVERNED, the newest Claim: (5730566948) names this branch; no open PR touches AGENTS.md; origin heads on the stem: only this branch. CI at 2026-09-18T13:45Z: 12 success · 11 skipped · 2 in progress (latest run per check), nothing red — the 13:31Z Check Changeset failure was the pre-label run, superseded by the labeled run (skipped).

Contract review of record (CONTRACT_REVIEW_TIER, in seat): PR #19042 comment 5730909983 — VERDICT PASS. §7 now names three classes of PR that never enter the merge queue on green alone, the third the maintainer's: 「a PR whose changed lines exceed 5,000 (additions + deletions, generated files included) — it lands only by a human merge, which is its review record」, and the arming instruction reads the size beside the file list and the author. The paragraph is re-flowed in place at net 0 (6 → 6 lines within the file's 120-byte budget). The sentence carries no card number: AGENTS.md's header forbids citations and check:pm-skill-id-lint enforces it — the dispatch's 「cite the ruling」 was the seat's error, the dev's reading correct; provenance lives in the PR body. Classes (a) / (b) keep their Prime Directive anchors; no directive added.

Path face: governed rule layer (AGENTS.md) ⇒ this PR stays a draft at the four-piece terminal: needs-user-decision on the PR, the final 维护者速读 posted there, review requested from os-zhuang and hotlong. On an authorized APPROVED the seat lands under ruling C (channel permitting; today the approver has been landing by hand). Lands in either order with PR #19033 (the rule's mechanism). This card closes on the merge (Fixes).

Landing — PR #19042 @ 8454706591 armed on the maintainer's approval (skills seat, 2026-09-19T02:17Z)

Tier H (AGENTS.md): approved by os-zhuang (GOVERNED_APPROVERS; review 5254146703 on this head at 2026-09-19T02:16Z) and readied by os-zhuang's hand. Ruling C: record 5730909983 (PASS at this head), check-clause2-carriers.mjs --pair 19042 exit 0, every completed check green (the Check Changeset red was stale — before skip-changeset — re-run green at 2026-09-19T00:56Z); needs-user-decision cleared; auto-merge SQUASH armed at 2026-09-19T02:17Z (the queue guard's pull_request leg was still running; the queue's merge_group leg judges the approval). The seat is clocking off on the maintainer's word — residue on this card (pm:dispatched → pm:done, unassign) is 留守 for the next seat or the maintainer's hand once the merge lands; the 收班简报 on the seat post (#7623) names it.
