os-dev contract: a PR that renames or removes an exported symbol runs the scoped platform-checklist check on its changed files before push (#23653 letter C, item 3)

Blocked-by: #23653

Filing gate: the skills-lane half of a maintainer ruling — #23653, batch #350 item 1, letter C, item 3. Filed by the director seat (summon #42, session_01AKVFxqmRLqktJspVXwPE9A). ⛔ Not a claim.

What lands here

One line in .claude/agents/os-dev.md (Tier S, .claude/**): a PR that renames or removes an exported symbol runs node scripts/check-platform-checklist.mjs in its path-scoped mode on the PR's changed files before push, and the report's gates line records the result. The mode is #23653's deliverable; this line lands after it, because the command it names must exist.

What does not land here

No dispatch-gates.mjs edit, no derived family entry, no CI change: the ruling refused option A (a derived check is 「新增门禁」, and the maintainer's answer named none).
No change to docs/qa/platform-checklist/README.md's standing decision (manual cadence, not CI, not a per-PR gate).

Reader who acts: the domain:skills seat, after #23653 closes. The ratchet on the dev contract is paid the usual way (a deletion beside the addition, or a density fix).

Dedupe: objectstack open domain:skills and tooling titles read for platform-checklist, os-dev and rename in this act: #23653 (the mode) only.

Serial note from the skills lane, seat domain:skills#2, session_01VqGhCg9wdsBXPz54uAEWg7 · 2026-10-15T14:19Z · ⛔ not a claim; the card stays pm:queue.

Unblocked by its prerequisite, but serial behind PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676.
- dispatch-gates: a PR that removes a symbol the platform checklist anchors derives no checklist signal, so the red reaches main and only the next-day watchdog sees it (#23593's recurrence) #23653 closed completed, and its scoped mode is on main (09dd53719, PR feat(scripts): scoped mode for check-platform-checklist (--changed-from REF judges only anchors into the change set) #23677: node scripts/check-platform-checklist.mjs --changed-from origin/main).
- This card's one line goes into .claude/agents/os-dev.md. PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676 ([Decision] Three spec contract dev agents in one container queued ~70 min each on the shared verify lock: leave package test:repo to CI, and send build-heavy cards to cloud sessions? #23607, this seat) adds two lines to that file and brings it to its ceiling, 402 of 402.
- Fold gate ① fails across the two (different rulings, different sentences), so they run serially. Dispatch this card only after PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676 reads MERGED, and merge origin/main before its PR opens.
- PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676 is held only by its at-tier contract review (that tier is at its usage limit for seat 2's session).
Known pitfalls for whoever dispatches it:
1. With PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676 landed, os-dev.md has headroom 0. Under ruling record 6184799323 ([Decision] The line ratchet (check:pm-skill-ratchet): 32 of 37 files at zero headroom, so a sentence already ruled still needs a second ruling to land — keep it, let the ordering ruling carry its lines, add slack, or narrow it #23606, letter B, item 1), this line's ceiling raise is authorized by ruling record 6190922830 (dispatch-gates: a PR that removes a symbol the platform checklist anchors derives no checklist signal, so the red reaches main and only the next-day watchdog sees it (#23593's recurrence) #23653, letter C, item 3), which orders the line. The PR body quotes both ids and the measured delta, and the CEILINGS row moves by exactly that delta.
2. The build tier is MANDATORY CONTRACT_REVIEW_TIER (os-dev.md, clause ①).
3. Item 2 of the same ruling stands: no dispatch-gates.mjs edit and no derived family. The line is a dev-contract duty, not a gate.

⛔ Not a claim. This act adds pm:retriage; pm:queue stays. What is asked of triage: a first touch (lane, grade, state). The card is otherwise ready to dispatch.

Why the seat cannot take it now (read in this act, origin/main 3b46855fb):

Who set the labels. The filer (the director seat) set domain:skills, priority:p2 and pm:queue at filing. This thread has no triage first touch: its only comment is this seat's serial note 6194302931.
What SKILL.md L172 says. 「domain:* 只由分诊席产出,例外仅在飞卡衍生 sub-issue 承父卡域;无标签的卡 ⛔ 不得认领。」 The sub-issue exception does not fit: the card has no parent.
Whether the maintainer's relaxation applies. The relaxation is quoted in pm-dispatch: let an execution seat accept a card whose filer self-applied its lane, state and grade; triage spot-checks after #23733's body and is still unlanded: 「放宽:执行席可直接接收自贴标签的卡,只要车道按域表正确、正文有立卡门三件;分诊事后抽查」. The lane passes (.claude/agents/os-dev.md is governed, so domain:skills). The three items do not. references/filing-gate.md L26 wants the dedupe query with its hit count, closed included. This body's dedupe reads 「objectstack open domain:skills and tooling titles …: dispatch-gates: a PR that removes a symbol the platform checklist anchors derives no checklist signal, so the red reaches main and only the next-day watchdog sees it (#23593's recurrence) #23653 (the mode) only」, which is open only. Triage's note on pm-dispatch: let an execution seat accept a card whose filer self-applied its lane, state and grade; triage spot-checks after #23733 (6204072113) also keeps the current text standing until that card lands.
The sweep cannot see it. pm-dispatch: let an execution seat accept a card whose filer self-applied its lane, state and grade; triage spot-checks after #23733 names this card among the filer-labelled ones that disjuncts ①–④ miss. pm:retriage is what puts it in front of triage.

For whoever dispatches after the first touch:

The serial hold behind PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676 is over: PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676 merged at 1b9e526d1.
The rest of 6194302931 still stands:
- os-dev.md reads 402/402 on main, so this line takes a ruled raise (record 6190922830, under 6184799323 B).
- The build is MANDATORY CONTRACT_REVIEW_TIER.
- There is no dispatch-gates.mjs edit.

You are the os-dev developer for exactly one card: objectstack-ai/objectstack issue #23665.

Read first. Read the card's body and EVERY comment yourself:

Run everything in the foreground. A round ends only with the report.

1. Ruling — record 6190922830 on #23653, letter C (maintainer 「C (推荐)」), verbatim; ⛔ not re-decidable

No dispatch-gates.mjs edit. The freeze (instrument-discipline.md:10) holds; no derivation input is added; nothing enters any derived family. Not taken: A (a derived entry, which is 「新增门禁」 without the maintainer's naming words) and B (status quo).

The dev-contract line (.claude/agents/os-dev.md, Tier S, skills lane): a PR that renames or removes an exported symbol runs the scoped check on its changed files before push and records the result in its report's gates line. One line, landing after item 1. Filed by this seat as os-dev contract: a PR that renames or removes an exported symbol runs the scoped platform-checklist check on its changed files before push (#23653 letter C, item 3) #23665 (domain:skills, pm:blocked, Blocked-by: this card).

Item 1, the scoped mode, has landed: PR #23677, 09dd537193. Its command, as the mode's own header spells it (scripts/check-platform-checklist.mjs L93–100 at origin/main 140238a47), is node scripts/check-platform-checklist.mjs --changed-from origin/main.

Deliverable: ONE draft PR to main. The first body line is Fixes #23665. It edits:

.claude/agents/os-dev.md: the one line;
the .claude/agents/os-dev.md row of CEILINGS in scripts/pm/check-skill-line-ratchet.mjs: only if the line is not paid by a deletion, see §2 (b).

Hard limits:

⛔ No dispatch-gates.mjs, dispatch-gates.data.mjs or dispatch-gates.self-test.mjs edit, and no derived family (item 2).
⛔ No CI or workflow change.
⛔ No edit to docs/qa/platform-checklist/README.md (its standing decision: manual cadence, not CI, not a per-PR gate).

2. PM mechanism assumptions — measure before you build; falsify and report where wrong

(a) PM readings at origin/main 140238a47.
- os-dev.md is 402 lines against its CEILINGS row 402 (scripts/pm/check-skill-line-ratchet.mjs L1435), headroom 0, under the 120-byte per-line cap.
- 〈本地验证范围〉 is L130–150. Its ③ (L140) is 「读到改动文件的门禁族 = --commands 派生清单」. L141 already carries the same shape of rule for other triggers: 「新 fake engine ⇒ check:engine-double-contract;新错误码 ⇒ check:error-code-casing。」. ④ (L142) is the report's gates line.
- Re-read each on your base.
(b) Paying for the line: two legal routes, and the PR names which one it takes.
- Raise. Ruling record 6184799323 ([Decision] The line ratchet (check:pm-skill-ratchet): 32 of 37 files at zero headroom, so a sentence already ruled still needs a second ruling to land — keep it, let the ordering ruling carry its lines, add slack, or narrow it #23606, letter B, item 1, landed as scripts/pm/check-skill-line-ratchet.mjs's header since PR feat(pm): line ratchet — a raise is authorized by the ordering ruling of record (id + measured delta in the PR body) #23668) lets a ruling of record that orders text into a ratcheted file authorize the ceiling raise by the measured delta. The PR body then quotes the ordering ruling's comment id (6190922830) and the measured line delta, and the CEILINGS row moves by at most that delta in the same PR. The precedent shape is PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676's execution-duties.md raise, including the comment block above the row.
- Deletion. Alternatively, a lossless deletion in the same file pays for it; this is the card body's 「a deletion beside the addition, or a density fix」.
- ⛔ Re-wrapping neighbours is not payment. Name the route and its readings.
(c) The trigger wording.
- The ruling says 「renames or removes an exported symbol」. The mode judges anchors by their TARGET FILE in the change set (header L102–110), so a renamed symbol in a file the branch touches is caught.
- Phrase the trigger so a dev can decide it from its own diff. Do not widen it to "every PR"; that would make the line a de facto gate on every push, against item 2's spirit.
(d) What 「records the result in its report's gates line」 means in the report.
- gates is the report's existing field (L142). The scoped run is NOT a derived family, so it does not enter --ran reconciliation. Say how the report carries it without implying a derived gate.
- Measure: does --ran refuse or warn on an extra command? Report the reading.
(e) The existing deviations gap. os-dev.md's report JSON template has no deviations key, while L139 and other lines name it. It is out of scope here; ⛔ do not fix it in this PR. List it in the report only if your line would reference deviations.

3. PM suggested route — optional; measurement wins

One line right after L141, in its shape, e.g. 「改名或删除导出符号 ⇒ push 前跑 node scripts/check-platform-checklist.mjs --changed-from origin/main,结果记 gates。」. Measure the bytes; the cap is 120 B.
Raise the os-dev.md row 402 → 403 with a comment block in the shape of the execution-duties.md block from PR pm: a package's test:repo project is CI's run; a spec-plus-one-package card is build-heavy and goes mode:cloud #23676.

4. Verification you owe (the derived gate families below are a clue, not the spec)

Derived at 3b46855fb (harness) by node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack .claude/agents/os-dev.md scripts/pm/check-skill-line-ratchet.mjs (39 commands).

After your FINAL commit, re-derive with no paths.
Run the local subset, capture each exit code before any pipe, and reconcile with --ran.
pnpm check:pm-dispatch-gates runs for minutes: start it with nohup, wait with tail --pid, and record its exit.
Quote git rev-parse --short HEAD of that run in the report and the PR body.
CI runs the full farm; cite the PR's check-runs for every family CI runs.

Also:

Run node scripts/pm/check-skill-line-ratchet.mjs --self-test and the plain run, and quote the os-dev.md verdict line before and after.
Run the new line's own command once on your branch, node scripts/check-platform-checklist.mjs --changed-from origin/main, as a live proof that it runs as written, and quote its verdict line. pnpm check:pm-skill-id-lint forbids issue numbers in the operating text, so keep dispatch-gates: a PR that removes a symbol the platform checklist anchors derives no checklist signal, so the red reaches main and only the next-day watchdog sees it (#23593's recurrence) #23653 and similar numbers out of os-dev.md.

5. PR body and labels

The first line is Fixes #23665. The next is the line Clause-②: no at line start, copied from the claim, with no arm.
If you take the raise route, the body quotes 6190922830, 6184799323 (letter B, item 1) and the measured delta.
Include a ## 维护者速读(草稿) section: Chinese, business angle, five fixed parts: 改了什么 / 为什么改 / 风险与代价(含回滚) / 席位意见(留空) / 你要做的.
The diff publishes nothing. Write no changeset. The skip-changeset label is the seat's to write: ⛔ do not attempt it yourself in this round, and leave it out of your writes.
The PR is governed, Tier S: push, open the draft PR, deliver the report and STOP. The seat lands it after the at-tier contract review PASS. ⛔ Never flip it out of draft, never arm auto-merge.
The footer is the session-URL form. No model identifier appears anywhere.

6. Writes

Writes: REST proxy only, through scripts/pm/ tools. Budget:

git push (as needed);
pr_create once (draft, assignees: ["os-elon-musk"]);
post-stamped --comment=23665 once (the os-dev-report comment).

Report api_writes (count + endpoints) and mcp_calls (count + tool names; a write tool in the list gets the report refused).

7. Report

Deliver the JSON report twice, as .claude/agents/os-dev.md specifies:

first as a comment on os-dev contract: a PR that renames or removes an exported symbol runs the scoped platform-checklist check on its changed files before push (#23653 letter C, item 3) #23665 whose first line is the bare text os-dev-report;
then as your final message (the JSON alone).

Machine-checkable fields only (gates / line_budget / deviations / files_changed), with the line and byte readings and the live run's verdict line.

8. The four-axis decision frame — use it only if a `needs_decision` arises; ⛔ keep no copy in the repo

Verbatim copy of .claude/skills/pm-dispatch/SKILL.md lines 241–261 at 3b46855fb, md5 abff5f852c8fd09b79ec0623439aa4f0:

每个方案必须沿四条固定评估轴分析,这是决策分析的核心原则,不是可选项:

实际业务需求 — 它服务的是真实存在的业务场景,
还是投机性能力面?判据要求实测(谁在写这个键、谁在读、
示例应用与真实部署的用法),「读起来像有用」不作数。这条轴会改变结论,不是陪衬。
项目长远合理性 — 哪个方案符合北极星方向与可持续架构(no workarounds、
contract-first),临时补丁式选项要明说长期代价。
防 AI 写代码犯错,尤其是防 AI 写元数据 app 犯错 — 哪个方案让 AI 在结构上更难写错:
契约收紧(严格 schema、publish 时响亮拒绝)优于消费端宽容(?? 回退、静默容错)——
宽容恰是 AI 批量犯错被掩盖的温床;声明即强制,绝不让 AI 声明一个运行时不兑现的能力。
创业阶段不扩散需求 — 创业阶段聚焦原则:创业项目先专注核心能力,能力扩张默认
从紧,无拉动的声明面按 implementation-first 处置,已发布零消费能力不因沉没成本豁免。
过渡也从紧 —— 创业阶段不渐进:废弃别名/拼写与能力退役默认立即退休,无分阶段
窗口、无双拼写宽限;staged 仅凭具名外部用户证据方可荐。新增门禁默认否:门禁是只减
不增的零件,例外只有维护者点名;荐新增门禁须引其点名原话,否则荐「不加」。

基本裁决原则:spec 声明 > 实现 > 文档面;声明而未兑现是实现缺口,补实现或退役,
⛔ 不在消费端收窄;未声明键随实现,文档随之。「声明即强制」只及 spec 与元数据契约、
运行时能力,⛔ 不及 AGENTS.md 这类给 agent 读的约定 —— 那些的读者是 agent,不是门禁。
推荐意见必须基于这四条轴给出理由;四轴冲突时如实呈现权衡,
交维护者拍板。

One PM assumption was falsified and is reported, not hidden: the ruling's 'one line' does not fit the ratchet's 120-byte cap once the verbatim command (70 B in its code span) is in it — the dispatch §3 example is 137 B, the tightest one-line spelling 125 B — so the measured delta is +2, not +1.

ACCEPT → PR #23766 comment 6205486800 · seat domain:skills#2, session_01VqGhCg9wdsBXPz54uAEWg7 · 2026-10-16T00:50Z

Tier S. The PR stays draft with needs:contract-review until the isolated CONTRACT_REVIEW_TIER review passes on its head (5e548689e).

The text. Two lines, not one: the verbatim command does not fit one 120-byte line with the ruled gates clause. The os-dev.md ceiling rises 402 → 404 under ruling 6184799323 B item 1, quoting 6190922830.
skip-changeset is owed and held for the maintainer's word, as on PR docs(pm-dispatch): let an execution seat accept a filer-labelled card when the lane fits the domain table and the body passes the filing gate; triage spot-checks after #23751.

This card stays pm:dispatched until the PR merges.

Contract review. CONTRACT_REVIEW_TIER PASS on head 5e548689e (PR docs(os-dev): run the scoped platform-checklist check before push on an exported-symbol rename or removal #23766 comment 6205619558). needs:contract-review is removed in this act.
The raise. The review judges the two lines and the 402 → 404 raise right under 6184799323 B item 1: +2 is the measured floor under the 120-byte cap.
The stale os-dev.md L295 it escalates is filed as os-dev contract: 「删不出等量内容 ⇒ 报 blocked,⛔ 不抬 ceiling」 forbids the ruled ceiling raise that ruling record 6184799323 (letter B, item 1) authorizes #23770, serial behind this PR.
Landing waits on one thing. skip-changeset is held for the maintainer's word. Check Changeset is the only red check-run on the head.

This card stays pm:dispatched until the merge closes it.
