## 维护者速读

- 改了什么:`.claude/agents/os-dev.md` 里只读读数那一行改写为「只读读数 ⇒ 不 commit、不开 PR,报
`status: "reading"` 贴决策卡;派发词要实测才建闭包跑测。」
- 为什么改:旧句把「不建闭包、不跑测试」也写成铁律,派发词要运行时实测(复现、计数)时两条规则直接冲突;现在「不 commit、不开
PR」是不变量,建与跑只是默认关闭。
- 风险与回滚:只改一行规则文本,不动任何代码与发布面;回滚即 revert 本 PR 的那一个 commit。
- 先看:`.claude/agents/os-dev.md` 第 355 行(〈何时停手不写码〉一节)。
- 两分钟验证:`git show origin/main:.claude/agents/os-dev.md | sed -n 355p`
与本分支同一行对比,应见「派发词要实测才建闭包跑测」取代「不建闭包、不跑测试」。
- 需要你做的:无,席位落地(Tier S,落地前欠一份契约复审档记录)。

## What changes

One line of `.claude/agents/os-dev.md` (the reading-order line in the
stop-and-do-not-code section, L355 on `origin/main`):

- Before: 「派发词标只读读数 ⇒ 不建闭包、不跑测试、不开 PR;报 `status: "reading"`,读数贴决策卡。」
- After: 「只读读数 ⇒ 不 commit、不开 PR,报 `status: "reading"`
贴决策卡;派发词要实测才建闭包跑测。」

The invariant of a reading order is now no commit and no PR, reporting
`status: "reading"` with the reading on the decision card. Building the
closure and running tests stay off by default and are allowed only when
the dispatch order asks for a runtime measurement.

## Why

A reading whose question only a run can answer (a repro, a measured
count) needs a build and a run, and the old line forbade both outright.
The triage audit on the card asked for 「不开 PR、零写」 as the invariant with
a purely static reading as the default.

## Tests

No code or test file changes; nothing to ablate (rules text only).

## Acceptance notes

- Grep of `.claude/**`, `AGENTS.md`, `CLAUDE.md` and `docs/agents/**`
for any other text forbidding a reading order from building or running:
one further hit,
`.claude/skills/pm-dispatch/references/dispatch-runbook.md:239` (测量先行卡 ⇒
只派只读读数 dev 或不派等裁). It names the order kind and forbids neither a build
nor a run, so it does not conflict and is left untouched.
- The file sits at its line ceiling (405 of 405) and every line is
capped at 120 bytes, so the rewrite stays one line (118 bytes). That
budget is why the line spells the invariant as 「不 commit、不开 PR」 rather
than also spelling 「零写」 and 「不 push」: no commit leaves nothing to push,
and the reading still lands on the decision card.
- A throwaway measurement file is not named on the line; it cannot land
because nothing is committed, and the AGENTS.md post-task checklist
already says to delete temporary artefacts.

## Verification

<details><summary>dispatch-gates at head 35cbbb9 (after merging
origin/main)</summary>

`node scripts/pm/dispatch-gates.mjs --commands --repo
objectstack-ai/objectstack`: 20 commands, all exit 0
(`check:doc-formula-expressions` first exited 3 on a missing
formula/lint build, rebuilt under the verify lock, then 0). `--ran`
reconciliation: 20 derived, 20 run, 0 NOT-MEASURED, 0 UNRUN. After the
main merge `check:pm-skill-ratchet`, `check:commit-card-trailers` and
`check:nul-bytes` were re-run at 35cbbb9, all exit 0.

</details>

## Human Minimum

- [x] 1. Schemas start as Zod; `packages/spec` holds no runtime logic.
(not touched)
- [x] 2. Every name I added uses the casing for its kind. (no names
added)
- [x] 3. No formatter ran; `pnpm lint` passes. (CI-owned run)
- [x] 4. One issue, one branch off an up-to-date `main`, one pull
request.
- [x] 5. A change that publishes carries a changeset, and both
declaration lines are filled in here and in the changeset. (publishes
nothing: `skip-changeset`)
- [x] 6. `packages/spec` touched: its generated artifacts are
regenerated and committed. (not touched)
- [x] 7. No hand edits to `content/docs/references/`,
`packages/*/CHANGELOG.md` or `content/docs/releases/`.
- [x] 8. Title, body and comments are in English. (the 维护者速读 section is
Chinese by rule)
