 ## 关键约束
 
-1. **只修改 `tests/acceptance/`** — 不碰应用代码、不碰 `skills/`、不碰 `scripts/`（除非是修复 agent_poller 或 create_failure_issue）
-2. **不碰 `tests/unit/`、`tests/integration/`** — 那是开发团队维护的
-3. **每次只处理一个 issue** — 不混入多个 issue 的改动
-4. **`Closes #<N>` 必须出现在 commit message 中**
-5. **本地验证必须通过再 push** — 至少 Layer A + Layer B
-6. **如果 Layer C（QE Audit）需要验证但 API 不可用** — 在 issue 下评论注明，标记 `--run-acceptance` 通过后 merge
