+## BUG-1464 | 存过别人的账户进首页即「页面出错了」
+
+- 状态：resolved
+- 首次发现：2026-10-27（issue #115，测试环境首页）
+- 最近更新：2026-10-27
+- 影响面：首页。正式站当时还没有这段启程代码，不受影响。
+- 用户现象：打开首页显示「页面出错了」。控制台是 `TypeError: Cannot read properties of undefined (reading 'length')`，以及 `app root error`。已保存的对话不受影响。
+- 触发条件：账户里存过至少一个有名字、有出生日期的别人。本机若还留着「先看某某的盘」的引导记录，会按 id 短路，暂时不触发。
+- 根因：`GET /api/chart-profiles` 的 `libraryProfileFromSubjectRow` 不返回 `birthTimeClue` 和 `rectificationCaseId`（库里没有这两列）。`normalizeChartLibraryApiRecord` 把 profile 原样摊开。2026-10-24 `4d63475caf` 起，首页每次渲染都对人物列表里有名字的别人调用 `missingOtherProfileStep`，日期能解析时读 `birthTimeClue.length`，字段不在就抛错，整页崩溃。
+- 修复：在 `normalizeChartLibraryApiRecord` 先铺 `emptyProfile`，再铺接口字段，最后写 `chartRelationship`。接口给了的字段仍以接口为准。不改库、不改接口。
+- 验证：`frontend/tests/chart-library-normalize-20261027.test.ts`。虚构的精确时间、大概时段、只有名字三种，经入口后 `emptyProfile` 的键都在；`missingOtherProfileStep` 分别为完成、`place`、`birth`，不再抛错。缺字段的接口形状在补齐前仍会抛 `length`。
+- 防复发：上面的测试锁住「人物列表 profile 键齐全」，以及首页用的同一条人物查找不再因缺字段崩溃。
+- 相关记录：`4d63475caf`。issue #115。
+- 复发自：无
+- 修复版本：分支 `codex/home-crash-saved-people-20261027`。

+# 进度：存过别人的账户首页崩溃（issue #115，2026-10-27）
+
+- 任务书：`docs/tasks/TASK-home-crash-saved-people-20261027.md`
+- 分支：`codex/home-crash-saved-people-20261027`（从 `origin/staging` `e34dc6b66` 新建；任务书基线 `941effe80`，其上只有这份任务书）
+- 执行：Grok。BUG-1464。开工时最大号 BUG-1463，本单用 1464。
+
+## 做了什么
+
+人物列表从接口拿回来时，先铺一份空的个人资料，再盖上接口给的字段。缺的 `birthTimeClue` 和 `rectificationCaseId` 变成空字符串，首页不再因为读不到长度而整页报错。接口已经给了的名字、日期、时段、关系保持原样。没有改数据库，也没有改接口。
+
+首页用的那条「找一个还没填完的别人」没有单独渲染整页 hook。崩溃就发生在这条查找上，测试直接跑同一条判断。渲染 hook 要整页账户状态，这一层已经能复现报错，也能证明补齐后不再报。

+| 检查 | 命令 | 结果 |
+| --- | --- | --- |
+| 类型 | `frontend\node_modules\.bin\tsc --noEmit -p frontend` | 退出码 0 |
+| 规范 | `frontend` 下 `npm run lint` | 0 error，122 warning（原有，未改） |
+| 新测试 | `node node_modules/tsx/dist/cli.mjs --test tests/chart-library-normalize-20261027.test.ts` | 2 通过，0 失败，0 cancelled |
+| 相关测试 | 同上，外加 `chart-library-other-profile`、`daily-starlanguage`、`people-archive-regressions` | 38 通过，0 失败，0 cancelled |
+| 全量 | `frontend` 下 `npm test` | 5268 项，5235 通过，33 失败，0 cancelled |
+
+33 条失败里，13 条与 `tools/agent-loop/windows-known-failures.txt` 的测试名逐条相同（数据库套件在 Windows 上的已知失败）。另外 20 条是 Windows 环境：路径变成 `G:\G:\`、shell / 部署脚本、docker 参数过长、临时目录被占用、三个「新建对话」预取超时。没有一条落在这次改的人物资料入口上。失败总数仍是先前 Windows 干净跑的 33。
+
+`npm run test:db` 本单不要求，未跑。没有登录态，没有在浏览器里打开首页。真机步骤写在 `docs/testing/ui-kit-migration-20261023.md` 的「首页进不去」一节。
+
+## 偏离
+
+- 分支从执行时的 `origin/staging` `e34dc6b66` 新建。任务书写的基线是 `941effe80`，两者之间只有这份任务书。
+- 没有渲染 `useProfileOnboarding`。首页崩溃发生在它每次渲染时的人物查找上，测试直接跑同一条判断。
