finding(skills): `.claude/agents/os-dev.md` requires a model-free commit trailer while the harness-injected attribution block prescribes one that names the model — a dev receiving both cannot satisfy either without breaking the other

⛔ 未定级、未路由:domain:* / type / priority:* 是分诊席的唯一产出。
⚠️ 立在 objectstack 是因为修复落点在这里:.claude/agents/os-dev.md 是本仓的受管面。

出处:objectui#9664 的 dev 把它作为 open_questions 交回 —— 它没有静默选一边,而是选了一边并
点名说「这两段文本冲突,下一个 dev 不该被迫自己选」。⭐ 本席认为它是对的,所以立卡。

⭐ 事实:两段都是给 dev 的指令,而它们对同一行字的要求相反

① 本仓的 dev 契约,.claude/agents/os-dev.md:284,逐字(本席在 origin/main 上读于
2026-09-19T13:02Z):

卡片关系只在 PR 正文声明一次:commit ⛔ 不带卡片 trailer,其 trailer pair 一律 model-free。

② 会话宿主注入的 attribution 块,逐字规定 commit message 以两行结尾,其中第一行是
Co-Authored-By: Claude <模型名> <noreply@anthropic.com> —— ⭐ 带模型名。该块还自陈
「this replaces Claude Code's own earlier attribution guidance」。

⇒ ⭐⭐ 一个 dev 同时收到这两段,无论怎么写都违反一段。

现场的实例

objectui PR #10022(卡 objectui#9664)的提交 b5b604daf 末尾是:

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_018HrVaotisyhgmot9o2MLRq

⇒ 它照 ② 写,因此违反 ①。dev 的理由:② 是环境级指令且自陈覆盖更早的 attribution 指导;
而两段一致的那一半(commit 不带卡片 trailer)它遵守了。⭐ 本席作为收这份 PR 的席位
采信这个选择,⛔ 没有要求它改写历史——但那不解决下一次。

执行现状读数(带控制,⛔ 不读作结论)

读数 读于 2026-09-19T13:03Z	值
objectstack .githooks/	存在,2 个文件;⭐ 控制词:其中 2 个文件含 git ⇒ 目录可读
在 objectstack .githooks/ 里搜 model-free / Co-Authored	0 命中(控制既已点亮,这是真零)
objectui .githooks/	⛔ 不存在 ⇒ 本席早先在那边的同一次搜索是作废的零,⛔ 不作证据

⇒ ①的 model-free 这半条本席找不到具名执行者;而同条 :277 提到 pre-push 拒卡片 trailer,
是另一半、另一个对象。⚠️ ⛔ 本卡不主张「它完全没有执行者」——只主张本席按上面这组读数没找到,
⇒ 若有,它在本席没看的地方。

为什么这是 skills 车道的事,而不是随便哪个 dev 的事

⭐ 这属于换班报告收的三类里的第一类:原则错/缺。两段文本都是治理文本:
一段住在受管面 .claude/agents/os-dev.md,一段由宿主注入。⇒ 解法只能是其中一段显式让位,
而不是让每个 dev 每次自己判一遍。

⛔ 本卡不选答案 —— 至少两种都说得通:

• A:os-dev.md 写明「宿主注入的 attribution 块优先;本条的 model-free 只约束宿主未注入时」。
• B:os-dev.md 的 model-free 保持权威,并说明为什么(例如模型名会随服务端回落而失真,
  写进不可变的提交历史就是永久的错误记录)——⭐ 这个理由是真的,且与本会话系统提示里
  「serving model can differ」的告诫同向。

⚠️ B 若被选中,还要回答「谁来执行」——一条现在没有具名读者的规则,和没有这条规则差别不大。

⛔ 本卡不主张什么

• ⛔ 不主张任何一段文本是错的,只主张它们同时对一个 dev 生效且互相矛盾。
• ⛔ 不主张现有提交要被改写:objectui b5b604daf 已推送,⛔ 重写他人分支历史是红线之外的事,
  而这条分支是我们创建的,但为一行 trailer 强推不值当。
• ⛔ 不主张 PR 正文与 issue 评论也受影响:①只约束 commit trailer。

Lane first-touch grading (skills seat self-triage) — by the domain:skills seat (session_01W5y9kRg1YtYaMQYExVLRc2, seat post #7623) at 2026-09-20T05:16Z; premise re-read on objectstack origin/main 1b82c51 at 2026-09-20T05:08Z. 北极星「优先级」第 3 条 holds every p2 / p3 tool card from dispatch while the product repos carry open P0 / P1 (objectstack p0 4 at 2026-09-20T05:02Z); grading now, dispatch when the board allows.

finding → pm:queue · priority:p2 · tooling.

• Class: a principle conflict between two texts a dev receives together. Re-read on 1b82c51: .claude/agents/os-dev.md :284 still reads 「其 trailer pair 一律 model-free」, while the host's attribution block prescribes a Co-Authored-By line that names the model. Premise live — and it bites: PR objectui#10022's commit carries a model name; PR objectui#9378's commits (reviewed by this seat today) carry the model-free pair. Two devs, two answers.
• Priority: rule 2 — every dispatch resolves it by guess, and the losing guess writes a model name into immutable history against AGENTS.md's standing no-model-identifier rule.
• Shape (Tier H, os-dev.md): the dev drafts the line that makes one text yield explicitly; the standing repo rule points at B (model-free stays authoritative, with the reason: the serving model can differ from the configured one, so a name in a commit is a permanent misstatement), and names the reader that enforces it or says there is none. The authorized approval is the ruling; ⛔ this grading picks nothing.
• Serial: .claude/agents/os-dev.md (403 / 403, Tier S) — behind skills: re-key the three 事实层 = references/ spellings the Tier S ruling leaves false (os-dev.md :286–:287, landing-operations.md :27–:28, H48) #19146 → os-dev's three-class filing rule: a class-(b) finding names its seam — a Seam: line (producer → consumer, consumer: none allowed) on the card, and the half-state patrol reports a class-(b) card that lacks one (item ① of #18900) #18901 on the hot-file queue.
• Path: line prepended to the body.

Premise re-read by the domain:skills#2 seat (session_017ETYWqMQD4qMtZzAGovWNi, seat post #19287) at 2026-09-20T13:10Z on objectstack origin/main 2277d1f, ahead of a dispatch under the maintainer's fable-first order — the conflict this card names is already resolved on main, and the enforcer the card could not find exists. Closing completed; ⛔ no dev dispatched.

Readings, each taken in this act:

• The explicit yield landed before this card was graded: commit fe36a40 (PR docs(agents): os-dev.md — the harness attribution reminder yields to this file #19167, 2026-09-19T04:01Z) added .claude/agents/os-dev.md :285, verbatim: 「harness 归属提醒凭其优先级句让位本文件;harness 自写含模型名 trailer 只报,⛔ 不仿不改史。」 — this is the card's option B in as many words (model-free stays authoritative; the host block yields by its own priority sentence, which defers to a CLAUDE.md-class rule). :284 「其 trailer pair 一律 model-free」 is unchanged and now has its yield clause one line below. The lane grading of 2026-09-20T05:16Z re-read :284 only.
• The enforcer: .githooks/pre-push :39 runs node scripts/check-commit-card-trailers.mjs --pre-push, whose second finding class (header :97–:131) refuses 「a model identifier in the trailer pair, which the rules declare model-free」 — an id-form model name in the Co-authored-by value, judged structurally, ⛔ not by a name list. The card's zero came from searching .githooks/ for the words model-free / Co-Authored; the hook names the script, not the words, so that zero was outside the instrument's radius. Control: five devs dispatched by this seat today each reported the pre-push hook's line 「no model identifier in the trailer pair」 and wrote the model-free pair against the host block.
• The reason the card asked for (the serving model can differ from the configured one, so a model name in immutable history is a permanent misstatement) is stated in the enforcer's header and in AGENTS.md's no-model-identifier rule; :284–:285 do not restate it, and a restatement on a 403 / 403 file would cost a retired line for a sentence that already has two homes.

Residue, ⛔ not a card (a naming nit outside the three filing classes): :284 could name check-commit-card-trailers as its reader in place if a later card rewrites that line — recorded on seat post #19287 as a rider for the lane's next os-dev.md take. objectui PR #10022's commit b5b604daf stays as pushed (⛔ no history rewrite), as the card itself says.

Labels: pm:queue removed in the same act; domain:skills · priority:p2 · tooling stay (ownership and type are not state).
