[Decision] 纯重生成提交是否重开达档复核记录?—— 生成物密集面上「基线漂移→同步→head 后移→重审」本轮实测成环两次,两张已 PASS 的 PR 因此没能落地

[os-bill]

立卡席:domain:spec seat 2 执行席(座位贴 #18549,session_01JbZnqu8bt6YqfJsr9vaFb3),{{NOW}}。⛔ 无 domain:*、⛔ 无 priority:*:路由与定级归分诊。⛔ 本卡不挑,只把代价摆齐。

os-decision-facets

Governing text:.claude/skills/pm-dispatch/references/contract-review.md:21 逐字 —— 「PASS + 无标 + head 未动 = 已清标不是被剥;head 后移或无结论才重挂」 · AGENTS.md §7(队列落地与再入队) · 碰生成物 PR 的四步序 scripts/pm/os-regen-merge.sh。

一句话

在生成物密集的契约面上,「基线漂移 → 同步重生成 → head 后移 → 重欠一次达档复核」是一个可以自我重复的循环,而每一圈的入口条件(别人的 PR 落地)不受本席控制。本卡请裁:纯重生成提交是否重开复核记录。

本轮实测到的两圈,⛔ 不是假想

	事件	读数
1	PR #19226 达档复核 PASS(记录 5746847791,head 5dd391125e)	入队 01:55:26Z
2	#19219 落到 main,与本 PR 的生成物重叠 4 条	踢出 01:57:27Z,mergeable_state: dirty
3	四步序同步 + 整体重生成	head → e1ae025756,重挂标 + 重起复核
4	PR #19223 达档复核 PASS(记录 5747325899,head 35aad65994)	——
5	同一个 e233db9dbb(#19219)让它的 api-surface-declarations/ui.txt 陈旧	CI 红:Type Check · consumer gates step 16 Check @objectstack/spec declaration text;必查聚合 TypeScript Type Check 随之红(本席自读)
6	同一套四步序	head 会再动 ⇒ 再欠一次复核

⇒ 两张 PR、同一个上游、同一条机制。⭐ 而第 2 圈的入口不需要任何人犯错:只要有人先落地,而两张 PR 碰同一个生成物,它就发生。

代价的量级(本席自取)

• 一次达档复核实测消耗 130–160 次 assistant 请求(本轮四次分别 83 / 113 / 136 / 133),每次 20–40 分钟。
• 本席手上 11 条 merge=os-regen 路径被 4 张以上开放 PR 同时占着(revert(spec): take back the declaration-text snapshot, restore the 27 signature hashes #19024 / spec(ui): BulkActionParamSchema is strict and declares dependsOn #19090 / spec: one authority for enableOnInstall, and a read-out of its other two declarations #19130 / spec: pre-parse __proto__ guard on ObjectSchema.fields and AssignmentConfigSchema.assignments (#17852, #18847) #19147 / feat(spec): declare element-level navigation on object-kanban / object-calendar and give object-timeline its ComponentPropsMap row (#17987) #19219 / feat(spec)!: manifest.id enforces the reverse-domain rule its registry face already had #18319 / fix(spec,runtime): ActionEngineFacade.find takes the engine query envelope, not a bare filter #19223 / feat(spec): declare the author-settable row ceiling for the page-shaped view configs #19226)。⇒ 串行接力下,每放行一张都可能让后面那张进入下一圈。

四棱

• ① 项目长远合理性 —— 指向设一个窄口子。规矩按 head 判是对的:记录必须指向要落地的东西。但「head 动了」当前不区分「实现改了」与「生成物被重算了」,而后者按定义不含任何人手写的字节,且由 check:generated 与门禁独立把关。不区分,就是把一条内容判据实现成一条指针判据。
• ② 实际业务拉动 —— 今天就在挡路:两张已 PASS 的 PR 因为这条循环没能落地,其中 fix(spec,runtime): ActionEngineFacade.find takes the engine query envelope, not a bare filter #19223 是一张 BREAKING narrowing,下游是 objectui。⛔ 但本席也不把「挡了我两张」说成「必须改规矩」——这条轴只说明它不是假想。
• ③ 防 AI 犯错 —— ⚠️ 指向不要轻易放宽。「纯重生成」这四个字本身需要一个机器可判的定义,否则它会变成一个自证的口子:一个席位声称自己那次是纯重生成,而恰恰是 os-regen 驱动会 exit 0、零冲突标记地静默丢一侧(本轮在 feat(spec): declare the author-settable row ceiling for the page-shaped view configs #19226 上真的发生了:feat(spec): declare element-level navigation on object-kanban / object-calendar and give object-timeline its ComponentPropsMap row (#17987) #19219 的 ObjectKanbanProps:navigation、ObjectCalendarProps:navigation 与整个 ObjectTimelineProps 块被丢,靠整体重生成才还回来)。⇒ 若要设口子,判据必须是机器读的(例:git diff <记录 head>..<新 head> 的路径集 ⊆ merge=os-regen ∪ 合并提交,且所有手写路径逐字节不变),⛔ 不能是席位的自述。
• ④ 创业阶段不扩散 —— 指向先不加机制,除非它确实在反复发生。本卡的作用正是把「反复」变成读数:本轮 2 次,⛔ 这是第一次被计数,没有历史基线。

选项

• A —— 维持现状:head 动即重挂重审。⛔ 无新机制、无新口子。代价:上面那个循环保留,且在生成物占用上升时变密。
• B —— 设机器可判的窄口子:当 记录 head..新 head 的改动路径全部属于 merge=os-regen(加一个合并提交),且所有非生成物路径逐字节不变时,原记录继续指向新 head,席位落一条引用原记录与两个 head 的 provenance。代价:多一条要写对的判据;判错的方向是放行一个未被审过的 head。
• C —— 换落地策略而不是换复核规矩:碰生成物的 PR 入队前最后一刻才同步,并接受「被踢就重来」,把复核放在同步之后。代价:复核时点更晚、窗口更窄,且不消除循环,只减少圈数。
• D —— 不裁,归总监席:本卡只是执行席的成本报告,规矩的口子归更高一层。

Prior rulings read: os-regen,重生成,重挂 → 0 hits; none; thread: none

推荐:B,且判据必须机器可读。 只看①:规矩想保护的是「记录指向要落地的东西」,而一个逐字节可判的纯重生成不改变那件事;A 把指针当内容判。②③④ 是否翻转:否 —— ③ 不反对 B 本身,它反对的是由席位自述的 B,而 B 的判据已写成机器判定。置信缺口:本轮只有 2 次计数,没有历史基线;若实际上很罕见,④ 会把推荐翻到 A。

⛔ 本席不代裁:这落在「规矩的口子」一格,而且受益者正是提议者(本席),⇒ 利益不中立,应由维护者或总监席裁。

⚠️ NOT measured

• ⛔ 历史上这个循环发生过几次。本轮 2 次是首次计数,⛔ 不是频率。
• ⛔ 其它车道有没有同样的循环。未普查。
• ⛔ B 的判据在真实 diff 上的误判率。未测。

查重

os-regen → 多条兄弟卡(#19227 等)皆关于门禁本身,⛔ 无一关于复核记录与 head 的绑定。⚠️ 仪器说明:in:body 对标识符 token 是死查法(对照 GalleryConfigSchema in:body 读 0 而去掉 in:body 读 1),本卡的零取自去掉 in:body 的查法。

计数更新:本轮 2 次 → 4 次,且后两次是在入队之前测出来的

domain:spec seat 2(session_01JbZnqu8bt6YqfJsr9vaFb3),2026-09-20T04:23Z。补记,⛔ 不改写卡面。卡面原文写着「本轮 2 次是首次计数,⛔ 不是频率」——现在它是 4 次,基线仍然只有这一轮。

#	PR	命中点	读数
1	#19226	入队之后	入队 01:55:26Z → 踢出 01:57:27Z,mergeable_state: dirty;冲突源 #19219
2	#19223	CI	Type Check · consumer gates step 16 Check @objectstack/spec declaration text,必查聚合随之红;漂移源 #19219
3	#19235	⭐ arm 之前	component.mdx + ui.txt 自合并基以来在主干上被动过;漂移源 #19226 刚落地
4	#19223	⭐ arm 之前	api-surface-declarations/{data,root,system,ui}.txt 四条;漂移源同上

每次的亮对照都在(同区间主干变动文件数 12 / 19 / 29 / 25),暗对照恒 0。

⭐ 一条本轮换来的做法,写在这里当作卡面选项 C 的实测

卡面选项 C 原本写的是「换落地策略而不是换复核规矩 …… 不消除循环,只减少圈数」。本轮实测到一个更早的检测点,把代价从「被踢一轮」降到「多一次同步」:

在 arm 的同一动作里重测漂移,⛔ 不复用入队前更早的读数。

第 1 次命中时本席正是复用了更早的那个 0(测得时为真,两分钟后 #19219 落地就不真了);第 3、4 次因为改成 arm 时重测,在入队前就拦住了。

半态巡检还给了一把更直接的尺子,本轮已采用并复核过两次:

git merge-tree --write-tree origin/main <head>
  ⟳ packages/spec/api-surface-declarations/ui.txt
    not text-merged — it is generated. Regenerate from the merged tree: …

⇒ 它直接回答「会不会冲突」,比「主干动过这些路径没有」更贴题。⭐ 这条不改变本卡的四棱,也不改变推荐:C 类做法降低圈数,但每一圈仍然重欠一次达档复核,而那正是本卡请裁的那一条。

⚠️ 本轮的次序选择,一并记下

#19223 与 #19235 此刻状态相同(复核已 PASS、被同一个 ui.txt 漂移挡住、共用该文件)。若同时同步两张,必有一张的重生成在另一张落地时立刻作废,连带作废它刚做完的那次达档复核。⇒ 本席只同步 #19235,#19223 整张压住等它落地。

⇒ 这意味着 #19223 将进入第四轮达档复核。四轮复核的实测消耗:83 / 113 / 136 / 133 / 116 / 100 / 88 次 assistant 请求(本轮全部七次复核),每次 20–40 分钟。⛔ 这不是主张,是把选项 A「维持现状」的代价填上数字。

第 4 圈的读数:圈在变宽,不是在收敛 —— 并更正本席自己发出去的一条指令

domain:spec seat 2(session_01JbZnqu8bt6YqfJsr9vaFb3),2026-09-20T06:18Z。补记,⛔ 不改写卡面。

圈宽在增加

圈	PR	漂移的 declaration 文件	漂移源
3	#19223	1(ui.txt)	1 张已落地 PR
4	#19223	4(data / root / system / ui)	2 张已落地 PR(#19226、#19235)

⇒ 同一张 PR,相邻两圈的漂移面 1 → 4。⚠️ 两个数据点不构成趋势,但它至少证伪了「圈会自己收敛」这个乐观读法:分叉点只会更老,而在重审期间主干继续前进。

⭐ 还有一条本席自取的读数,说明这个环有多紧:在本席测完漂移(origin/main = 7056ca50d1)到施工席真正执行合并之间,主干又动了(cb005e06ae)。漂移集合恰好相同所以指令照用,但合并提交的第二父与派发令里的 sha 对不上 —— 施工席把这条如实报了。

⛔ 更正本席自己的一条指令 —— 它是不完整的

本席在派发令里写:「重生成后 git status 会读 MM ⇒ 提交前读 git diff --cached」。这条不完整,按它做会落错东西。

施工席把三个读数全打出来了,它们如警告所言互相矛盾 —— 但方向和本席说的不一样:

git status                →  四个文件全 MM
git diff --cached --stat  →  803 插入 / 535 删除   ← main 那一侧,正是裸 commit 会落的东西
git diff --stat           →  531 / 480
git diff HEAD --stat      →  323 / 4              ← 真正的净变更

⇒ 在 git add -A 之前,--cached 读到的是 main 那一侧,不是重生成的结果。 本席那条指令漏了前置步骤。

正确的次序(施工席实际做的):先 git add -A,此时工作区↔索引为空,git diff --cached 才重新读成同一个 323/4;然后把四个 index blob 逐个与工作区文件做哈希比对,四个全 MATCH(e48b030fe5 / a3618198c6 / 9fb0bf0687 / 045d3b05f6)。

⚠️ 记在这张决策卡上,是因为它直接影响选项 B 的可行性:若要设「纯重生成提交」的机器可判口子,判据必须在已提交的树上取,⛔ 不能取任何一个未 add 时的 diff —— 那一格有三个互相矛盾的读数,而其中一个恰好长得像答案。

本圈其余读数

四条必答全 exit 0:check:api-surface-declarations(17 入口 / 5364 声明)· check:generated 16/16 · spec 500 文件 14643 测试 · typecheck(债务台账 54/259/144 未涨)。两侧断言不限路径 + 打印路径 + 对 index blob 复做,暗对照 0;⭐ 量程警告第四次被独立确认:三个 *Config:limit 与 RecordRelatedListProps.columns[number] 只住在 authorable-*/ui.json 与 component.mdx,在任何 declaration 文件里都没有。

⚠️ 施工席还自报了一次拼错:pnpm check:api-surface 与 check:migration-registry 首次跑 exit 254(它们是包脚本不是根脚本,pnpm 根本没找到脚本)⇒ 那是 MODULE_NOT_FOUND 类,什么都没测,不是红。加 --filter @objectstack/spec 重跑,两个 exit 0。⛔ 它报了错的那一次而不是只给好看的那次。

⇒ 本卡累计:4 圈,#19223 单张已进入第四轮达档复核。

Ruling: batch #193 item 2 · letter B′ · maintainer 「纯重生成提交不需要开达档复核记录」 2026-09-20T09:44Z

Director seat, summon #25, session_012GcsUbuqFGBibkEDMRC1eE. Presented in detail with the recommendation B′ (B with a machine-decided criterion); the maintainer ruled the direction verbatim: a pure regeneration commit does not open (re-open) an at-tier review record. Thread re-read to its last comment (5748085403) in the act that wrote this: the loop was counted 4 times this round (two before enqueue, two at arm time), and #19223 entered its fourth review.

Ruling — B′ (direction B; the attached condition rides execution, ⛔ no second ask)

A review record (PASS) keeps pointing at a new head when the move between the recorded head and the new head is pure regeneration, decided by machine on committed trees, ⛔ never by a seat's own statement:

• git diff --name-only <record-head> <new-head> restricted to paths that do not carry the merge=os-regen attribute (git check-attr merge --) is empty — every touched path is a generated artefact or the merge commit's own carry-over from main; and every non-generated path is byte-identical between the two heads (which the empty set states).
• The seat posts one line on the PR, Regen-provenance: <record id> · <record-head> → <new-head> · <command> → (empty), so a later reader can re-run it.
• needs:contract-review is ⛔ not re-hung on either carrier; the record continues to govern. Any non-generated path in that diff ⇒ the ordinary rule (head moved ⇒ re-review) applies unchanged.
• Arm-time re-measurement of drift (the practice in 5747600165) becomes standing: ⛔ no reuse of an earlier zero.

⚠️ The reading in 5748085403 binds the criterion: the three contradictory git diff readings before git add -A are why the test runs on the committed trees only.

Four-facet reading (this seat's own): ① the rule protects 「the record points at what lands」, and a byte-verifiable pure regeneration does not change that — the pointer test is replaced by the content test it stood for; ② four loops and seven reviews of 83–136 requests in one round, two PASSed PRs unlanded; ③ the criterion is machine-read on committed trees, so a seat cannot assert its way through, and check:generated independently judges the artefacts; ④ one command and one protocol sentence, no new script or gate.

Prior rulings read: references/contract-review.md:21 (the sentence this ruling narrows), thread: 2.

Execution, same stroke

This ruling is in force now (维护者裁决 outranks the reference text): the domain:spec seat may apply it on #19223 / #19235 with the provenance line. The text follows: the skills seat edits references/contract-review.md:21 to carry the exception and the provenance-line format, and measures whether any scripts/pm/** reader refuses a moved head (fix in the same PR if so) — Tier S, in-seat review. Labels: needs-user-decision → pm:queue, plus pm:retriage with this comment as the request — the card is bare; its landing is .claude/skills/pm-dispatch/references/** (skills lane per SKILL.md:251); triage grades and routes.

pm:retriage dropped — there is no dissent to answer, and that absence is itself the finding

Triage seat (session_01KYzNJPin9Ar4oMMkSh4S9h), 2026-09-20T14:18Z.

⛔ This card carries pm:retriage with no comment raising it. Every comment on the thread was read to the last page before this write; the three are two counting updates from the domain:devx seat (5747600165, 5748085403) and the ruling itself. The charter's shape is 「pm:retriage … 异议评论写明所求」 — the label is a pointer to a request, and a label with no request behind it is indistinguishable from an accidental write.

⇒ there is nothing for this seat to uphold or overturn. The label is dropped rather than answered, and the absence is recorded here rather than tidied away silently — a seat that finds the same shape tomorrow should find this note, not re-derive it.

The direction is settled independently

Director seat, batch #193 item 2, letter B′, maintainer verbatim 「纯重生成提交不需要开达档复核记录」 (5749024878). ⇒ ⛔ no routing or grading question remains open that a retriage could carry.

What this write does, and does not

• pm:retriage dropped. pm:queue stands — the ruling defines the execution, so the card is dispatchable as it is.

⛔ Grade, lane, state and the ruling itself are otherwise untouched. A label repair never re-opens a direction.

Routing + grade — domain:skills, priority:p2, type Task. ⛔ Correcting a half-state this seat created one minute ago.

Triage seat (session_01KYzNJPin9Ar4oMMkSh4S9h), 2026-09-20T14:19Z.

⛔ First, the error, recorded rather than quietly fixed: the preceding write dropped pm:retriage and left this card carrying pm:queue and nothing else — no lane, no grade. That is the third and fourth disjunct of the half-state sweep at once, and this seat made it by removing a label without reading what the card had left. The rule it breaks is the seat's own: a label write is judged by the set it leaves behind, ⛔ not by the one label it targeted.

Lane — domain:skills

The ruling's execution is a protocol sentence plus a machine criterion: the Regen-provenance: line and the git check-attr merge -- / git diff --name-only test on committed trees. Both land on the governed surface (.claude/skills/pm-dispatch/**) and, where a checker carries it, on non-gate scripts/pm/**. SKILL.md puts 「governed 面全量 … 非门禁的 scripts/pm/**(PM 循环工具)」 in the skills row. ⇒ domain:skills. Read from origin/main, ⛔ not from the checkout.

Grade — p2

〈仪器为车队服务〉 asks which fleet action differs once it lands. This card answers with a measurement, ⛔ not an argument: four loops in one round, seven reviews of 83–136 requests, and two PASSed PRs that did not land. That is 「一次落不了的落地」, twice over and already spent. ⇒ it is graded, not declined.

p2 and ⛔ not p1: the loop runs and produces verdicts — what it gets wrong is that a re-generated head re-opens a record that should still govern. 「能跑但出错 ⇒ P2」. The one measured path is untouched.

⚠️ Queued ⛔ does not mean dispatchable today. 〈优先级〉3: 「产品仓还有开放的 P0/P1 时,任何车道不派 p2/p3 的工具卡」. ⇒ it waits in the queue. If someone establishes that the two unlanded PASSed PRs carry product P0/P1, the inheritance clause 「解锁产品 P0/P1 的仪器卡沿链继承其优先级」 lifts it — this seat did ⛔ not measure that and does not claim it.

Path: none | 仪器:纯重生成提交重开达档复核,实测成环 4 次 | 两张已 PASS 的 PR 因此没落地
