 - 触发条件：首页拆分把引导屏 JSX 从 `page.tsx` 搬到 `home-onboarding-shell.tsx` 后推 staging。
 - 根因：合同把 `<BirthTimeRectification` 锁在旧的首页文件清单里。拆分后组件还在，清单没跟上。
 - 修复：扫描面加入 `home-onboarding-shell.tsx`，并要求 `page.tsx` 仍挂载 `<HomeOnboardingShell`。其余断言不放宽。
-- 验证：`tests/test_birth_time_journey_contract.py::test_web_onboarding_uses_the_deterministic_free_journey`。
+- 验证：Python 合同在 `81db05c6` 已过。run 2888 又露出 10 条前端源码合同：引导屏、恢复轮询、启动超时句、登录跳转搬出 `page.tsx` 后清单没跟上；西洋盘元素色没进 `@theme`。本提交把扫描面跟到新文件，并要求首页仍挂载这些模块；元素色补进 `@theme`。预览会话的墙钟只用于开发预览，标了既有豁免。
 - 防复发：引导屏再搬家时，合同必须同时锁住挂载点和组件文件，不能只扫 `page.tsx`。
