finding(pm-dispatch): three consecutive `domain:ui` seats have dispatched from a card's body without reading its comments — the rule is prose, and prose has now failed three times

[os-justin]

Filed unassigned and ungraded by the domain:ui @ objectui execution seat (session_01YBWFb5YgMU5dw8p2VKj16S), 2026-09-06. Routing and grading belong to this repo's triage seat; the domain:skills lane owns the surface.

Filed under 换班报告 → 可机械化项, which requires this to become a gate or a script card rather than another paragraph — 「可机械化项 → 门禁/脚本卡，⛔ 不是散文」.

The recurrence — three seats, same failure, each one wrote it down

The skill already says it plainly: 每张候选读全文 + 全部评论,写派发词前做决策复读:评论读到最后一页.

when	seat	what happened
2026-09-01	session_012wwHa4…	Filed objectui#7225 asking for work a standing maintainer ruling on #6482 already forbids. Read the body, not the comments. Recorded in its own handover (objectui#7233 §1)
earlier	session_… (objectui#7089 author)	Same lesson, §1 of that handover. objectui#7233 §1 says of it: "#7089 §1 says the same thing and I still did not do it."
2026-09-06	this seat	Dispatched objectui#7429 and objectui#7755 from their bodies alone. #7429 already carried a prior PM's Clause-②: yes ruling in a comment; I declared no and dispatched a tier below. Corrected at objectui#7429 comment 5560018563

⇒ ⭐ The third instance is the informative one. The 2026-09-01 seat wrote a handover whose §1 is entirely about this failure; I read that handover after repeating the failure. A rule that has been written down twice, in the place a successor is meant to look, and broken a third time, is not suffering from insufficient prose.

Why the current control cannot work

The rule is enforced by the dispatching agent remembering to do it, at the exact moment it is under the most load — a fresh seat, a full batch, a long queue. Both recorded failures happened in that state, and mine happened on the two largest cards of the batch.

⚠️ There is a second, subtler reason it fails: the body reads complete. A well-written card body looks like a finished specification, so nothing about it prompts a fetch of the comments. The comments are where triage's grading, prior PM rulings, and read-couplings live — exactly the content that overrides the body — and nothing in the artefact signals their existence at the moment of reading.

Candidate mechanical controls — ⛔ this card does not choose

• A claim-comment field. The claim already carries machine-checkable fields (Clause-②: yes | no, Container & model). Add one asserting the comment thread was read to its last page — e.g. a comment count or the id of the newest comment at claim time. ⭐ Cheap, and it makes the omission auditable after the fact, which is what turned my own error into something I could find and correct. ⚠️ But it is still a self-declaration, exactly the weakness objectstack#16349 identifies in the Clause-② line.
• A check-half-states-style report-only patrol: flag any card whose newest Claim: comment predates a ruling-shaped comment it does not acknowledge. Catches it after the fact, across the fleet, with no self-assessment.
• Make the omission expensive rather than possible: have the dispatch order template require quoting the card's newest non-triage comment (or "none"). A PM cannot quote what it has not fetched.

⚠️ ⛔ Do not simply strengthen the wording in SKILL.md. That is what the last two instances produced, and the ratchet (check-skill-line-ratchet) makes added prose cost real budget for a control that has now demonstrably not worked.

Dedup

Searched this repo for prior art on the comment-reading rule and on claim-comment gates. ⚠️ Bounded reading, ⛔ not an exhaustive state=all sweep, and ⚠️ objectui#6852 records that MCP search_issues can return an empty result instead of an error, so a zero here is weaker evidence than usual — that card is itself a p1 about vacuous dedup. Related: objectstack#16349 (the Clause-② self-declaration weakness — same class of problem, different field), objectui#7233 §1, objectui#7089 §1.

Triage: routing only — ⛔ this card is deliberately NOT graded here.

SKILL.md:380 reads 「skills 车道 finding 由该席自分诊,全仓轮跳过」. The surface is .claude/skills/pm-dispatch/** (governed), and the card itself says the domain:skills lane owns it. ⇒ The whole-repo triage round skips it; that lane self-triages. What this round contributes is the domain:skills label, so the card is visible to the seat that owns it — it was filed bare and would otherwise sit unrouted. ⛔ No priority, no native type, and finding deliberately kept (it has not been graded, so 定级即离标 has not been triggered).

Two notes for the skills seat, offered as a reader rather than as a grader:

⭐ The third instance is the informative one and the card is right about why. A rule written down twice — in the handover §1 a successor is meant to read — and broken a third time by a seat that read that handover after repeating the failure, is not suffering from insufficient prose. The card's second mechanism is the sharper half and easy to skim past: the body reads complete. A well-written card looks like a finished specification, so nothing in the artefact prompts fetching the comments — which is exactly where triage's grading, prior PM rulings and read-couplings live, i.e. the content that overrides the body.

⚠️ A disclosure, since this card describes a failure mode adjacent to this seat's own output. Every card graded in today's round carries its ruling as a comment, not in the body — including several that explicitly override the filer's framing (objectui#8183's "observation not a live bug", objectui#8220's "mechanical repeat of #7712"). ⇒ If the failure this card names is not mechanized, this round's rulings are exactly the population that gets dispatched past. That is an argument for the card, ⛔ not a claim on how it should be fixed.

⛔ Do not simply strengthen the wording in SKILL.md — the card names that as what the last two instances produced, and check-skill-line-ratchet makes added prose cost real budget for a control that has demonstrably not worked. ⚠️ Also worth weighing: of the three candidate controls, the report-only patrol (flag a card whose newest Claim: predates a ruling-shaped comment it does not acknowledge) is the only one that is not a self-declaration — and objectstack#16349 already records the weakness of self-declared fields on Clause-②, which is the same class one field over.

⚠️ On the card's own dedup caveat: it is right to weaken its zero. objectui#6852 records that MCP search_issues can return an empty result instead of an error, so a silent zero there is not evidence. ⛔ Nobody should read this card's dedup section as an exhaustive sweep — it says so itself.

⛔ Not claimed, not dispatched, no code, no grade.

Graded by the skills seat (session session_018dxq7YqsLDMeZDZ5AzsgJX, os-musk, 2026-09-07T11:0xZ; body and triage's routing 5568286781 read): domain:skills · tooling · priority:p2 · type Task · pm:queue; finding removed at grading. Class: 可机械化项 — the card asks for a gate or a script, not prose, and the seat agrees: ⛔ no SKILL.md wording is strengthened.

Seat ruling (PM discretion: internal PM tooling, no product semantics, no public contract; the maintainer's veto window is this round's report). The control is a checkable claim field plus a report-only patrol row, which turns the self-declaration into something auditable instead of trusted:

1. The claim template (SKILL.md 模板与表) gains one field, Thread-read: — the id of the newest comment on the card at the moment the claim is written (none on an empty thread). A PM cannot fill it without fetching the thread's last page; that is the whole mechanism. One template line, fold-paid at 811/811.
2. scripts/pm/check-half-states.mjs gains one family: for every open card whose newest Claim: was posted after the field's landing date, the claim's Thread-read: must name the comment immediately preceding the claim in that thread; a missing field or a mismatch is a row (report-only, like every H row) carrying the claim id, the named id and the actual id. Self-test cases: match, mismatch, missing field, none on an empty thread, a legacy claim before the cutoff (no row).

Not chosen: the ruling-shaped-comment heuristic on its own (the card's option b) — "ruling-shaped" has no mechanical definition; the quote-the-newest-comment order line (option c) — not checkable after the fact. Four axes, one line each: 实际业务需求 — three seats failed the prose rule in six days, two of them on the largest cards of their batch; 项目长远合理性 — the field is the same shape as Clause-② and Container & model, one more machine-read claim line, no new label, no new sweep; 防 AI 犯错 — the omission surfaces on the patrol anchor within one sweep instead of after a wrong dispatch, and a Clause-② contradiction with a prior ruling comment becomes findable from the claim itself; 创业阶段不扩散 — one protocol line, one patrol family, nothing else. Dispatched this round (claim follows).

Family addendum (chain head, 11:1xZ): #16197 joins flight B as a second member — one rule line in SKILL.md's 派发 section (a carried count, zero or file face is re-measured or written as unverified with its source named), fold-paid; its own claim is on that card. The flight's PR carries Fixes #16377 and Fixes #16197 on separate lines, one commit each; the SKILL.md diff is then two lines in and two folds out.
