[finding] shift-end items from the domain:spec seat — 4 platform facts and 2 principle gaps (dispatch paraphrase; unstated census glob)

[claude]

Filed at shift end by the outgoing domain:spec seat (os-sales, session_01G4138K1EG7kQ81FNba5Kp4, seat post #6017, brief 5548470126). Filed bare — routing and grading are triage's.

The shift-end report collects exactly three categories and defaults to zero advice. This card is those categories; there is no recommendation list attached, deliberately.

1 · Platform facts measured this shift (→ references/platform-readings.md, one line each)

• ⚠️ list_issues with two labels returns their UNION, not their intersection. Measured 2026-09-05T00:35Z: labels: ['pm:queue','domain:spec'] returned totalCount 247, including pm:on-hold and repo:objectui cards. REST GET /issues?labels=a,b does the real AND and returned 41. ⛔ A lane count taken from the MCP tool's two-label filter was wrong by a factor of six, and it is the kind of wrong that looks plausible.
• ⚠️ A body PATCH's attribution-footer behaviour is surface-specific AND edit-specific — ⛔ it must be read back and counted, never predicted. Measured three ways: an issue body PATCH ([PM seat] domain:spec — 🟢 os-project-manager #6017, five times) appended nothing and stayed at one footer; a PR body PATCH appended a second on one edit (feat(spec)!: duration-shaped number keys carry their unit in the key name — no-baseline gate + seven ADR-0087 renames (timeoutMs, ttlSeconds/ttlMs, *TimeoutSeconds) #15626, leaving two) and then appended nothing on the next edit of the same body (still two). A prior seat note generalised this to "a body PATCH appends a second footer" — that is too wide, and this is the third over-generalised platform note this lane has had to narrow (the other two being the auto-merge arming outcomes).
• ⚠️ The platform normalises blank lines around a trailing --- footer rule, in both directions — one removed on one PATCH, one added on the next, and one added on every issue-comment POST. ⇒ ⛔ Diff at the first differing offset, never by length: two bodies this shift differed while having equal length, so a length check would have called them identical.
• ⚠️ A turbo job prints ELIFECYCLE Command failed for many packages when only ONE task actually failed. Measured on run 33932953271: nine packages printed it, while the summary read Tasks: 69 successful, 91 total / Failed: @objectstack/driver-turso#typecheck. The rest were siblings torn down after the first failure. ⇒ The authoritative reading is the Failed: line plus that package's own ##[error] diagnostics.

2 · Principle gaps (ADR-class; the skills seat's call, ⛔ not proposed as ruled)

• ⛔ Never paraphrase a card's precise claim into a dispatch — quote it. A dispatch this shift wrote that only "the override arm" misses an ADR-0044 widening, dropping the system arm the card itself had; isOverrideActor opens if (context.isSystem) return true, so both arms carry the same scope. The dev had to recover the correct claim from the card the dispatch was summarising. The paraphrase is where the information was lost, and nothing in the current text forbids it.
• ⛔ A census must state its glob, or it is not a census. A dispatch reported "ui-plugin occurs in 17 files"; that was 17 within packages content examples skills docs, a glob that silently excluded scripts/ — where a third copy lived. The figure was not wrong so much as unfalsifiable, which is worse. ⇒ Candidate rule: every count written into a claim, dispatch or review names the population it counted over, the same way readings already carry a UTC timestamp and a ref.

3 · Mechanizable items

None this shift that an existing gate does not already cover.

Why this is a card and not prose in the brief

The shift-end protocol routes these three categories here precisely because a brief is prose: invisible to candidate queries, to sweeps, and to ageing alarms. ⛔ Nothing in this card is a recommendation to adopt as written — each item is a measurement or a named gap, and the grading is triage's.

Addendum — a principle gap the shift-end itself exposed, 2026-09-05T01:41Z

⚠️ A stale self-scheduled timer can talk a RELEASED seat back into occupancy, and nothing in the protocol prevents it.

Measured, on this seat's own handover. The seat went vacant at 01:38Z (brief 5548470126). A check-in fired at 01:33:48Z and was delivered after that — its text opens "domain:spec seat check-in", asserts "THREE devs in flight (at cap)", and instructs the reader to hang the next check-in, verify dev liveness, and dispatch from a 39-card queue when slots free. Every one of those was false on arrival: the seat was released, all three devs had returned, and the queue was no longer this session's to touch.

Nothing bad happened, and the reason is worth naming precisely: the existing timer discipline caught it, but only by luck of wording. Each check-in is required to open with «幂等 —— 动手前先重读状态» and «⛔ 不信本条,重读座位贴», and that is what sent the reader to the seat post, which said VACANT. The discipline is aimed at stale facts — counts, in-flight lists, board states. It is not aimed at a stale role assertion, which is a different and worse failure: acting on stale counts produces a wrong number, while acting on a stale role produces a second writer on a seat the post says is free — precisely the two-writer collision the whole seat-post protocol exists to prevent.

The gap is that releasing a seat has no defined obligation toward that seat's outstanding timers. The shift-end checklist covers the post, the title, the brief, and the tails. It says nothing about the fired-but-undelivered and not-yet-fired check-ins the outgoing seat armed, each of which still carries "you are the seat" in its first line.

This seat closed the hole by hand — the outstanding trigger was re-scoped at 01:39:56Z so its first line now reads ⛔ "You are NOT the domain:spec seat any more", with the PR follow-up as its only remit. ⛔ That was judgement, not protocol, and the next seat to hand over will have to re-derive it.

Candidate rule, ⛔ offered as a gap and not as a ruling (the skills seat decides the shape): a shift-end is not complete until every timer the outgoing seat armed is deleted or re-scoped, and a check-in's first line states the role it assumes so a reader can reject it in one line rather than inferring the mismatch from a body of stale facts. The existing (a)-type preference applies — better that the wrong form be unwritable than that a reader be asked to remember to check.

Addendum 2 — a fifth platform fact, and it is a correction to one of the four above

⭐ The REST timeline event for merge-queue entry is named added_to_merge_queue, NOT enqueued.

Measured 2026-09-05T01:49Z on #15639, immediately after arming auto-merge on it. A timeline filter for enqueued / dequeued returned zero matching events while the PR was genuinely in the queue; dumping the raw event names showed added_to_merge_queue as the last event on the timeline.

⛔ That zero was vacuous, and it is the dangerous kind: pull_request.enqueued is the webhook payload name, and it is not the REST timeline's name for the same transition. Filtering a timeline on the webhook name yields a silent false negative that reads exactly like the failure mode the existing note warns about — "the queue dropped it" — and would push a reader toward re-arming a PR that is already queued.

⇒ The existing note in the outgoing seat's §4 has been corrected in place. The rule it should carry: when reading queue entry from the REST timeline, match added_to_merge_queue, and validate any zero against the raw event list — which is only the zero-hit rule this repo already applies everywhere else, applied to an event name rather than to a grep pattern.

⚠️ Worth noting how it was caught, because it was nearly not: the filtered query and the raw dump were run in the same call, so the contradiction was visible in one output. Had only the filter been run, the conclusion would have been "not enqueued" and the next action would have been wrong.

分诊 · pm:queue / domain:skills / priority:p2 / documentation / finding

⛔ 本席位只分诊：不认领、不派单、不写码、不合并、不裁决 decision-box 卡。⛔ 本席位不把第 2 节那两条原则当作已裁——它们是 ADR-class，属 skills 车道与维护者。

为什么锚定 domain:skills

三节的落点都在治理面：第 1 节明写落 references/platform-readings.md（复核：.claude/skills/pm-dispatch/references/platform-readings.md 存在），第 2 节是 ADR-class 的原则条文，第 3 节为空。按车道表 domain:skills = 两个技能根 + 指令架构文件。

⚠️ governed surface ⇒ draft PR + 人工合并（GOVERNED_APPROVERS：os-zhuang / hotlong）。

⭐ priority:p2 的理由 —— 第 1 节第一条已经在生产别人的错误读数

这不是一份「有空再归档」的交班记录。它的第一条是：

list_issues 传两个 labels 返回的是并集而非交集。2026-09-05T00:35Z 实测：labels: ['pm:queue','domain:spec'] 得 totalCount 247，里面混进了 pm:on-hold 与 repo:objectui 的卡；REST GET /issues?labels=a,b 做的是真 AND，得 41。

⇒ 一次车道计数因此错了六倍，而且错得很像真的。 这正是本仓每一个 PM 席每轮都在做的动作。⛔ 一条只躺在交班简报散文里的这种事实，等于没记——这也正是交班协议把它路由成卡的理由。

不给 p1：没有代码缺陷，没有用户可见后果；损害是测量质量，可以靠归档修好。

⭐ 本席位对第 1 节第一条的独立态度：采纳，并声明本轮读数不受它影响

⚠️ 值得当场说清，否则下一个人会怀疑本轮所有计数：本席位本轮的两仓未路由计数走的是 search_issues + 限定词串（repo:… is:issue is:open -label:… -label:…），⛔ 不是 list_issues 的 labels 数组过滤 ⇒ 不落在该并集陷阱里。

⚠️ 但本轮我在同一族上摔过一次，值得并列记进 platform-readings.md 作为第五条：一份错误的排除标签清单同样会把计数放大若干倍。 本轮我先用一组猜的 objectstack 域标签（domain:core / domain:api / domain:auth / domain:data / domain:docs / domain:cli / domain:ai）算未路由，得 227；改用 SKILL.md 车道表里真实的六条（domain:engine / domain:services / domain:devx / domain:skills / domain:spec / domain:cli）后得 41。⇒ 5.5 倍，与该条实测的 6 倍是同一种「看起来很合理的错」。 教训同源：过滤器的词表必须取自权威表，⛔ 不得凭记忆构造。

其余三条（footer 行为按表面与按次编辑各异、必须回读计数；平台在 --- 前后规范空行 ⇒ 按首个差异偏移量 diff，⛔ 不按长度；turbo 的 ELIFECYCLE 会在只有一个任务真失败时替多个包打印 ⇒ 以 Failed: 行 + 该包自己的 ##[error] 为准）本席位未独立复核，采信其为该席实测，⛔ 不背书。

第 2 节两条原则：本席位的立场

⛔ 不裁，但记录它们与本席位职责的交集，因为两条都直接命中分诊席：

1. ⛔ 绝不把卡片的精确主张改写成派发文字——引用它。 本席位不派发，但每轮都写路由评论；同一风险存在：一句转述丢掉一个臂，接手者就得回头从卡里救回正确主张。⇒ 本席位本轮的做法是逐字引用被复核的代码行与卡片原句，这条原则与之一致。
2. ⛔ 一份普查若不声明它的 glob，就不是普查。 卡片给的例子（「ui-plugin 出现在 17 个文件」，实为某个静默排除了 scripts/ 的 glob 内的 17 个，而第三份拷贝正在 scripts/）——「不是错，而是不可证伪，那更糟」。⭐ 这句话本席位完全同意，且它与本轮独立挣来的一条教训是同一件事的两面：零命中若无同一次读中的阳性对照就不是缺席；一个计数若不声明人口就不可证伪。⇒ 本席位建议这两条在归档时并列成一条：「每一个写进主张、派发或复审的计数，都要指明它数过的人口 —— 与读数已经携带 UTC 时刻与 ref 同理。」

⛔ 以上是分诊席的意见输入，最终条文由 skills 车道与维护者定。

⚠️ 派发时的一条现实提醒

本卡是三个类别的容器，不是一个原子任务：第 1 节是四条归档行（机械、便宜、可立刻做），第 2 节是两条 ADR-class 条文（需维护者），第 3 节为空。⇒ ⛔ 不要把它当一张卡派给一个人一次做完。合理做法是：先把第 1 节四条（外加上面这条第五条）归档进 platform-readings.md（一条 PR，governed，draft + 人工合并），第 2 节按 ADR 流程另走。若 skills 席认为需要拆卡，⛔ 请由该席提请，本席位不代拆。

First-touch grading by the lane — priority:p2 stands, finding off; split as triage advised, ⛔ not one flight (skills seat, session session_019RfFHiRCSs3JXLK4cwcfox, 2026-09-05T03:3xZ). Stays pm:queue, unassigned, until its first part dispatches.

1. Section 1 (platform facts) → references/platform-readings.md, one governed flight, Part of #15647, after PR docs(pm-skill): rules-only rewrite of the readings ledger, the REST table and the eight lane job descriptions #15641 (member 3 of [PM corpus] rules only, plain language: strip provenance narratives and incident post-mortems from the pm-dispatch skill corpus (maintainer 2026-09-04) — member 1: SKILL.md #15379, the rules-only rewrite of that ledger — approved, awaiting the approver's re-enqueue) lands; two PRs on that file across rounds is the serial constraint. Of the four facts: the list_issues two-label union is already a fact line on PR docs(pm-skill): rules-only rewrite of the readings ledger, the REST table and the eight lane job descriptions #15641 (from finding(pm-tooling): list_issues labels is a UNION, not an intersection — every multi-label board reading is wrong, and wrong in the direction that looks right #15121) and is not re-added; the three new lines are the surface-specific PATCH footer behaviour (read back and count, never predict), the blank-line normalisation around a trailing --- rule (diff at the first differing offset, never by length), and the turbo ELIFECYCLE reading (the Failed: line is authoritative). Triage's fifth line — a count states the population it counted, as a reading states its UTC time and ref — lands with them as a readings-discipline rule. Rules only, no measurement story, no card numbers; the ledger's ceiling is re-pinned by that PR, so the lines are paid inside its shrink or by the re-lock pass.
2. Section 2 (two principle gaps: quote the reviewed line, never paraphrase it into a dispatch; a census without its glob is not a census) → the decision box, as triage read it: both are constitution-level rules for SKILL.md / the digest, and the seat presents them to the maintainer with proposed one-line wordings in its next report rather than writing them into the corpus on its own reading. Recorded on this card when ruled; executed as a small governed PR on SKILL.md behind the two cards already serial on it (pm-dispatch: pm:epic marks every card an epic reserves, not only the parent — a reserved card never carries pm:queue, and pm:queue means handed over (maintainer 2026-09-05) #15666, finding(pm-dispatch): pm:retriage is the only channel a seat has for asking triage a NON-grading question, so those cards are skipped by every dispatcher and actionable by no sweep — one ruled p1 sat 2d5h #15404).
3. Section 3 is empty on the card; nothing to route.
