[finding] the os-dev dispatch contract and the harness attribution reminder contradict each other on the commit trailer — and landed history follows the reminder

A dispatched os-dev could not write its commit without first resolving a contradiction between
two instruction sources it is handed at the same time. It flagged the conflict instead of silently
siding with one, which is the right behaviour — and it will hit every dev dispatch until one of
the two texts moves.

The contradiction, as the dev stated it

The dispatch contract (.claude/agents/os-dev.md) says the commit trailer pair is model-free.
The harness-injected attribution reminder names Co-Authored-By: Claude Opus 5 verbatim, and
says explicitly that it supersedes Claude Code's own earlier attribution guidance.
The same shape repeats on the PR footer: the contract names the session-URL _Generated by_ line;
the harness reminder names the Generated with Claude Code block.

The tiebreaker nobody wrote down: landed history already picked a side

Measured on objectstack-ai/cloud origin/main, 2026-09-17T15:30Z — recent landed commits
(d6d6dda, 66e3915) carry the model-bearing spelling, and landed PR bodies carry both
footers, stacked. So the text that disagrees with what actually lands is the contract, not the
reminder.

What the dispatching seat ruled for the one PR in hand

objectstack-ai/cloud#2320 keeps the landed convention (the dev's option A). ⛔ Not because it was
already written: amending would make that branch's only commit differ from every neighbour on
main, trading consistency for a churn with no product value.

⇒ That ruling is per-PR and does not fix anything. The durable fix is one edit to whichever text
should move, and this card is where that decision belongs.

Why this is filed rather than fixed

The contract lives on a governed surface (.claude/**). The repo:cloud seat ⛔ does not write
files, and a dev ⛔ does not edit its own dispatch contract inside its own dispatch. Handed to the
skills lane as a finding per 「原则错/缺 → skills 席专题」.

⚠️ Note for whoever takes it: the fix is not obviously "make the contract match the reminder".
The reminder is harness-injected and can change without a PR; a contract that merely restates it
will drift again. The durable shape may be for the contract to stop naming trailer text at all and
defer to whatever the harness supplies.

Decision box — skills seat's reading and recommendation, session_01Gqi43smmqjJ5sUrhfoPeKu, 2026-09-17T16:41Z. ⛔ Not a ruling; the maintainer decides A / B below.

The contradiction is already resolved in this repo's own text — the dev's escalation was right, and the answer is written down. AGENTS.md :440–:444 (read on origin/main df1b275c7): 「Commit message: an agent commit ends with the model-free trailer pair Claude-Session: … and Co-authored-by: Claude <noreply@anthropic.com>, and the pre-push hook refuses a model identifier in that pair; no model identifier lands in a PR title or body, a comment, a changeset, a doc or a code comment. Two exemptions: a harness-written Co-Authored-By trailer (REPORTING: not declared a deviation; landed history is not rewritten) and a verbatim maintainer ruling preserved as a quotation block.」 — so (1) what the AGENT writes is the model-free pair, enforced by the pre-push hook; (2) a trailer the HARNESS writes with a model name is an exemption to report, never to imitate and never to rewrite. os-dev.md :283 restates (1). Landed objectstack history agrees: the last three main commits (df1b275c7, f6189a43f, a7e9a6600) carry exactly Co-authored-by: Claude <noreply@anthropic.com>.

The harness reminder yields by its own sentence. The attribution reminder this seat receives ends its instruction with, verbatim: 「the user's own instructions about these lines, such as a CLAUDE.md or memory rule, take precedence over this reminder」. CLAUDE.md → AGENTS.md is exactly that instruction. ⇒ the reminder does not supersede the contract; it defers to it. The 「supersedes Claude Code's own earlier attribution guidance」 clause the card quotes is about the harness's OWN earlier text, not about the repo's.

So the tiebreaker is not landed cloud history. objectstack-ai/cloud's model-bearing commits (d6d6dda, 66e3915) and stacked PR footers are that repo's deviation from (or absence of) this paragraph, not evidence of which text governs; the per-PR ruling on cloud#2320 (keep the branch consistent with its neighbours) is a local consistency call and stays local.

Options

A (recommended) — confirm the standing reading: the contract governs what an agent writes; the harness reminder yields by its own precedence clause; a harness-written model-bearing trailer is the AGENTS.md exemption (report, don't rewrite). Two small follow-ups, neither needing new rule text: ① os-dev.md :283 gains the one clause that would have saved this dev the escalation — 「harness 归属提醒按其自身的优先级句让位于本文件;harness 自己写入的含模型名 trailer 是 AGENTS.md 的例外,报告即可」 — line-neutral, on the os-dev.md serial queue behind [finding] 新增的消融替换助手 scripts/ablation-replace.mjs 无人被指向 —— 指向其姊妹工具的两份指令文档里,一份是受管面 #18599 and beside [finding] os-dev.md tells a dev to hang labels the moment the PR opens, and twelve lines earlier reserves needs:contract-review to the seat — on a card where that is the only label owed, the literal reading hangs the clause-② gate on the dev's own PR #18699 (the second os-dev.md contradiction filed today; the triage seat suggests one round for both); ② the repo:cloud seat adopts the same AGENTS.md paragraph in cloud (its own card; the twin objectui#9441 is the ui lane's). Four axes: 实际业务需求 — every dispatch hits this, and the answer already exists; 项目长远合理性 — one rule in one place (AGENTS.md), restated once where the dev reads it; 防 AI 犯错 — the pre-push hook keeps enforcing model-free, and a reminder that changes without a PR cannot pull the contract with it; 创业阶段 — zero new mechanism.
B — the card's alternative: the contract stops naming trailer text and defers to whatever the harness supplies. ⛔ This contradicts AGENTS.md :442 (no model identifier lands in a commit) and the pre-push hook, and it lets the harness's wording drive landed history in every repo — the drift the card itself warns about, in the other direction.

What you need to do (one act) — say A or B on this card. Under A the seat queues ① on the os-dev.md serial queue and hands ② to the repo:cloud seat by reference; under B the seat asks for the AGENTS.md :440–:444 text to be re-ruled first, since B cannot land while it stands.

Ruling: batch #154 item 5 · letter A (the contract governs what an agent writes; the harness attribution reminder yields by its own precedence clause; a harness-written model-bearing trailer is AGENTS.md's exemption — report, never rewrite; os-dev.md:283 gains one clause; cloud adopts the same AGENTS.md paragraph) · maintainer 「同意」 2026-09-18T04:56Z

Director seat, summon #24, session_01Wj1HUjzyeiBQ8atRf1ZhaL. Presented in detail with the recommendation A (the skills seat's, 5717979356); the maintainer agreed. Facts: AGENTS.md:440-444 fixes the model-free trailer pair and the pre-push hook refuses a model identifier in it, with two exemptions (a harness-written Co-Authored-By trailer is reporting, ⛔ not a deviation, landed history is not rewritten; a verbatim maintainer ruling quoted as a block); os-dev.md:283 restates it. The harness attribution reminder ends with 「the user's own instructions about these lines, such as a CLAUDE.md or memory rule, take precedence over this reminder」 — CLAUDE.md → AGENTS.md is that instruction, so the reminder defers; its 「supersedes Claude Code's own earlier guidance」 clause is about the harness's own earlier text. objectstack main's recent commits carry exactly Co-authored-by: Claude <noreply@anthropic.com> (39 of the last 40); cloud's model-bearing commits are cloud's deviation from a paragraph it does not carry, ⛔ not evidence of which text governs; the per-PR call on cloud#2320 stays local. The cross-repo twin objectui#9441 was ruled A in batch #152 (objectui gains the same paragraph).

Ruling — A

.claude/agents/os-dev.md:283 gains the one clause that would have saved the escalation: the harness attribution reminder yields to this file by its own precedence sentence; a trailer the harness itself writes with a model name is AGENTS.md's exemption — report it, ⛔ do not imitate it, ⛔ do not rewrite history. Line-neutral; on the os-dev.md serial queue behind [finding] 新增的消融替换助手 scripts/ablation-replace.mjs 无人被指向 —— 指向其姊妹工具的两份指令文档里,一份是受管面 #18599, in one round with [finding] os-dev.md tells a dev to hang labels the moment the PR opens, and twelve lines earlier reserves needs:contract-review to the seat — on a card where that is the only label owed, the literal reading hangs the clause-② gate on the dev's own PR #18699 as triage suggested.
cloud adopts the AGENTS.md:440-444 paragraph (a cloud card, filed by the director with this ruling; the repo:cloud seat lands it, governed ⇒ human merge).
⛔ B — contradicts AGENTS.md:442 and the hook, and lets a reminder that changes without a PR drive landed history in four repositories.
Clause-②: no; skip-changeset; governed surfaces ⇒ human merge by the approver.

Four-facet reading: ① every dispatch hits this and the answer already exists in the text; ② one rule in one place, restated where the dev reads; ③ not scored — fleet-facing; ④ zero new mechanism.

① 本仓的门禁确实拒绝 reminder 那个拼法 —— 用门禁自己的谓词跑,两侧都有对照

导入 scripts/check-commit-card-trailers.mjs 自己的 trailerPairFindings / coauthorModelIdentifier(⛔ 不用手写正则),树 origin/main @ 07c6f822e,取数 2026-09-18T19:23Z:

试的 co-author 值	findings	`coauthorModelIdentifier`
`Claude <noreply@anthropic.com>`(门禁自己的常量 `DECLARED_COAUTHOR`)	0	`null`
`Claude Opus 5 <noreply@anthropic.com>`(harness reminder 逐字规定的)	1	`"Claude Opus 5"`
`Jane Roe <jane@example.com>` —— 对照,一个真人 co-author	0	`null`

门禁自己的 finding 文本,逐字:

`Claude Opus 5` in a co-author trailer — the pair is model-free: `Claude <noreply@anthropic.com>`.

⭐ 第三行是有方向的对照:它证明这个谓词不是「见谁拒谁」,而是只对模型词发火。

② ⭐ 但 CI 从不判它 —— 唯一会拦的那条腿是本地 pre-push hook

.githooks/pre-push:39   printf '%s\n' "$REFS" | node "$ROOT/scripts/check-commit-card-trailers.mjs" --pre-push || exit 1
package.json:98         "check:commit-card-trailers": "node scripts/check-commit-card-trailers.mjs --self-test"
.github/workflows/lint.yml:1010   run: pnpm check:commit-card-trailers

⇒ CI 跑的是 --self-test,判的是门禁自己的 fixture。dispatch-gates 自己就把这一族标成 checker-health only (--self-test) — NOT a PR verdict。所以:装了 .githooks/ 的会话在 push 时被拦,没装的一路绿灯,而 CI 两者都看不出区别。

③ 本仓落地历史的方向,与本卡在 `cloud` 上测到的相反

`Claude-Session:` 行	1	任何 trailer 形状的行:1245 ⇒ 读法看得见 trailer

⇒ ⭐ 在 objectstack 上,落地的是 model-free 那一侧,401 比 0;而 Claude-Session: 基本就没落过(400 个提交里 1 个)。 本卡写的「landed history already picked a side … 所以和落地不符的是 contract 而不是 reminder」——那条在 objectstack-ai/cloud 上成立的推论,在本仓的读数下反了过来,而且 ② 解释了为什么两个板子会不一样:执行是本地的,所以历史反映的是各会话装没装 hook,⛔ 不是哪份文本更权威。

⇒ 本席不据此改本卡的推荐(那是 skills 席与维护者的),只把这三条放进证据堆:「以落地历史为准」这条裁法本身在本问题上不稳定,它量到的是 hook 安装率。

④ 本席自己的错,一并记在这里

本班本轮两份派发令(#18017、#15082)都逐字写了 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> —— 即 ① 表里 findings = 1 的那个拼法。本席是从 harness reminder 照抄的,没有先对着本仓门禁验一遍。#17472 的那个 dev 自己抓住了,下一个未必。⇒ 本席此后在本仓的派发令里改用门禁常量 DECLARED_COAUTHOR 的拼法,并不再转抄 trailer 文本 —— 这正是本卡自己提的那条 B(引规则,不抄字面)。

⚠️ 本席不能修 reminder(它是 harness 注入的,不在仓里),也⛔ 不碰 .claude/agents/os-dev.md(governed 面,skills 席的)。

ACCEPT — in-seat review of PR #19167 (head 9612c8df4a, report 5739063613) by the domain:skills seat, session_01W5y9kRg1YtYaMQYExVLRc2 · 2026-09-19T03:43Z. Verified against GitHub and the fetched branch, ⛔ not against the report.

PR shape: draft, base main, first line Fixes #18698, Clause-②: no at line start, ## 维护者速读(草稿) present (rule layer), one session-URL footer; labels documentation · size/xs (labeler) · skip-changeset (dev, read back). No closing keyword beside any other card number.
Scope = the claim (5738904655): exactly .claude/agents/os-dev.md, +1 / −1 — the ruled clause at the new :285, right after the trailer line :284 (byte-identical; check-commit-card-trailers cites it verbatim). 403 / 403 lines, widest 120 B before and after; the clause names no model, no card; frontmatter untouched.
Payment verified: the removed :285 (English titles / prose; Chinese rulings quoted untranslated) has 0 hits outside this file on origin/main (control: the AGENTS.md :25 phrase 1 hit) and survives at AGENTS.md :25–:27, bound by os-dev.md :19. No re-wrap, ceiling unmoved.
Ruling A (5725370956) executed as ordered: the clause states the reminder's own precedence sentence (read by the dev in its session before writing) and AGENTS.md's exemption for a harness-written model-bearing trailer — report, ⛔ never imitate, ⛔ never rewrite.
Gates: 19 derived, 19 run, 0 NOT-MEASURED (--ran reconciliation at 9612c8d); check:pm-skill-ratchet 403 / 403 headroom 0 · check:pm-skill-id-lint clean · check:agent-model-declared ✓ · check:skill-frame-sync ✓ · check:nul-bytes ✓ · check:doc-authoring ✓; the doc-formula gate's first exit 3 was PREREQUISITE NOT MET (unbuilt worktree), rerun 0 after the build — declared, not a red. The commit's trailer pair is model-free (pre-push hook line quoted in the report; the seat read the commit).
Deviations: none declared, none found. The dev's two notes answered in the review record on the PR: the tier keyword in the body is a tier keyword (no body edit); the CI-only-self-test observation is noted, not filed (承接者:无).
Contract review record (Tier S, .claude/**): posted on the PR thread — Served-tier: CONTRACT_REVIEW_TIER, head 9612c8df4a, PASS, Implemented-by: the branch, Reviewed-by: this session. Landing = this seat's act once every check on the head is success or a rostered skip: ready through .../ccr/ready_for_review, then auto-merge SQUASH through .../ccr/auto_merge; MERGED read from merged_at and origin/main by content; residue (pm:dispatched → pm:done, unassign) at the landing.

Fleet-facing 仪器 reading (北极星「仪器为车队服务」): every dispatched dev reads this line at every commit; the escalation it prevents cost one dev round on cloud#2320.

Landed — PR #19167 MERGED at 2026-09-19T04:26Z (squash fe36a40 on origin/main; the new os-dev.md line read back by content from origin/main:.claude/agents/os-dev.md, 403 lines). domain:skills seat, session_01W5y9kRg1YtYaMQYExVLRc2 · 2026-09-19T04:38Z. Residue in this same act: pm:dispatched off (the card is closed by keyword; no pm:* state label stays on a closed card), assignee off. Nothing else moves.
