fix: keep western labels near their planets and chats on the current person

Cap planet captions at 30 degrees with a third ring, fall back only within the current person's sessions, and load self when the people catalog fails.

+## 2026-09-25 — 西洋盘标签不再读错星座，删对话不再跳到别人（待验收）
+
+- 西洋盘行星标签最多离开真实位置 30°，放不下时用更靠内的第三圈，不再被引到另一个星座扇区。
+- 删除当前这个人的最后一条对话后，打开的是这个人的新空对话，不会打开别人的历史。
+- 人物列表暂时读不到时，聊天按本人继续，顶栏写「暂时读不到其他人」，不再整页停在错误屏。
+- 重叠的行星点击圆按离点击更近的那颗星计算。旧的星盘资料面板文件已删除。
+- Skill 版本不 bump。64 张真实引擎虚构盘的重叠检查通过；登录页、整页移动端和部署还没做。

+## BUG-1034 | 西洋盘标签为避让离开行星所在星座
+
+- 状态：待验收（代码已落地，未部署）
+- 首次发现 / 最近更新：2026-09-25 / 2026-09-25
+- 影响面：`western-wheel-layout.ts`、`western-wheel-svg.tsx`。不改黄经、宫头或接口。
+- 用户现象：标签只写星座内度数。避让把标签推到另一个星座扇区后，读者会按标签位置读错星座。验收抽样里 48% 的盘有标签偏离行星超过 30°，最大 115°。
+- 触发条件：`4d801e53` 起，两圈放不下时在 ±180° 内搜索位置，并用长引线连回行星。
+- 根因：字形碰撞框、同环最小间距和命中圆中心距叠在一起，搜索又没有偏移上限。
+- 修复：显示角与真实黄经相差不超过 30°，且必须落在本星座或相邻星座。两圈放不下时使用更内侧的第三圈。文字盒和命中圆中心仍要避开已占位置。相交的点击圆按最近圆心归属。
+- 验证：Node 22 定向测试里，1990-01-01 夹具、64 张真实引擎虚构盘重叠为 0，且每张标签偏移 ≤30°、不越过相邻星座。固定种子分散盘重叠率 ≤1%。45° 内塞进 11 颗星的几何压力盘不再要求零重叠。
+- 防复发：渲染结果上的 `data-longitude` / `data-display-longitude` 被测试断言 30° 与相邻星座。真实引擎 64 盘仍要求重叠为 0。
+- 相关记录：BUG-1033。
+- 复发自：BUG-1033 的避让搜索没有偏移上限。
+- 修复版本：`codex/round-0925-followup-20260925`，未部署。
+
+## BUG-1035 | 删除当前人物的对话后打开另一个人的对话
+
+- 状态：待验收（代码已落地，未部署）
+- 首次发现 / 最近更新：2026-09-25 / 2026-09-25
+- 影响面：会话删除回退、首页当前会话推导、咨询保存失败回退、人物列表合并。
+- 用户现象：当前看的是 B 时，删掉 B 的最后一条对话，会打开 A 的对话。
+- 触发条件：内存里的会话列表按人保留、侧栏按人过滤，但回退选择取的是整份列表里第一条非校正会话。
+- 根因：三处回退没有用 `sessionMatchesSubject`。列表合并只增改，服务端已删除的行会留在内存里。
+- 修复：回退先按当前人物过滤。这个人没有其他会话时新建一段空对话。某个人的列表被完整刷新时，服务器不再返回的行从内存移除；未保存的空草稿和其他人的行保留。
+- 验证：定向测试锁住回退过滤、首页第二条查找，以及完整刷新会丢掉该人物已不在返回里的有内容会话。
+- 防复发：源码合同要求回退调用带 `sessionMatchesSubject` 的过滤。
+- 相关记录：BUG-1030。
+- 修复版本：`codex/round-0925-followup-20260925`，未部署。
+
+## BUG-1036 | 人物列表接口失败时整页聊天不可用
+
+- 状态：待验收（代码已落地，未部署）
+- 首次发现 / 最近更新：2026-09-25 / 2026-09-25
+- 影响面：首页会话加载、人物目录、顶栏切换器。
+- 用户现象：`/api/chart-profiles` 失败后，首页进入可恢复错误屏，历史和聊天都打不开。同一次打开里 `/api/account` 被请求两次。
+- 触发条件：会话列表先读账户，再串行读人物目录；人物目录失败被当成整个列表失败。
+- 根因：`loadSubjectCatalog` 失败会抛出，会话列表把它写成 `session_list_unavailable`。账户读取没有共享。
+- 修复：人物目录失败时按本人加载历史和对话，不进错误屏。切换器写「暂时读不到其他人」，只列出本人。目录恢复后自动刷新。同一次加载里的账户请求共享同一个进行中的结果。
+- 验证：会话列表生命周期测试里，人物目录 503 不再产生 `session_list_unavailable`，账户仍在，且不是登出。
+- 防复发：该用例改为断言降级后的 boot，不再把目录故障当成整页失败。
+- 相关记录：BUG-1032。
+- 修复版本：`codex/round-0925-followup-20260925`，未部署。
+
+## BUG-1037 | 年运命令里的年主辅助函数调用了不存在的名字
+
+- 状态：待验收（死代码已删除，计算路径未改，未部署）
+- 首次发现 / 最近更新：2026-09-25 / 2026-09-25
+- 影响面：`scripts/jyotish_engine.py` 的 `cmd_tajika`。年运命令的实际返回仍走 `calc_year_lord`。
+- 用户现象：没有用户可见变化。未定义的 `calc_panchadhikari_year_lord` 包在从未被调用的 `_resolve_tajika_year_lord` 里，外面的 `except Exception` 会在一旦被接上时吞掉异常。
+- 触发条件：该辅助函数没有调用点。基线即如此。
+- 根因：上游辅助函数被嵌进来，但依赖的函数不在本仓，调用又被宽泛异常吞掉。
+- 修复：删除这段没有调用点的辅助函数。`year_lord` 结果仍由 `calc_year_lord` 产生。
+- 验证：源码中不再出现 `calc_panchadhikari_year_lord` 与 `_resolve_tajika_year_lord`。未改年运命令的返回字段。
+- 防复发：BUG 记录写明这是死代码删除，不是年运算法变更。
+- 相关记录：BUG-1028。
+- 修复版本：`codex/round-0925-followup-20260925`，未部署。

+# PROGRESS · 0925 收尾单（2026-09-25）
+
+## 状态
+
+代码在 `codex/round-0925-followup-20260925`，基线 `origin/staging` @ `b8712dad`。BUG-1034 / 1035 / 1036 / 1037。未部署。登录页、整页移动端、全量 `npm test` 与 `next build` 还没在这轮跑完时，不把定向通过写成全量通过。
+
+## 做了什么
+
+- T1：行星标签相对真实黄经不超过 30°，并且留在本星座或相邻星座。两圈不够时用半径 100 的第三圈。64 张真实引擎虚构盘重叠为 0。固定种子里行星铺开的那部分重叠率不超过 1%。45° 内放进 11 颗星的几何压力盘不再要求零重叠，原因写在测试文件的三栏说明里。
+- T2：删除、地址回退和保存失败的回退都先按当前人物过滤。当前人物没有其他会话时新建空对话。这个人的列表如果已经是完整一页，服务器不再返回的有内容会话会从内存去掉；没保存的空草稿和其他人的行还留着。
+- T3：`/api/chart-profiles` 失败时按本人加载历史，不进错误屏。切换器显示「暂时读不到其他人」，只列出本人，恢复后自动再读。同一次加载里的 `/api/account` 共用同一次进行中的请求。
+- T4：删除了没有引用的 `chart-library-panel.tsx`。点击圆重叠时按最近的行星圆心选择。`cmd_tajika` 里从未被调用、又引用了不存在函数的 `_resolve_tajika_year_lord` 已删除；年运命令仍用 `calc_year_lord`，返回字段没有改。
+
+## 断言三栏
+
+写在对应测试文件里，不在这里重复改口：西洋盘 11° 全局间距改为 30° 上限；512 张压力盘的零重叠改为分散盘 ≤1%；人物目录 503 不再期望整页 `session_list_unavailable`；首页和回退的会话查找加上当前人物过滤。
+
+## 还没做
+
+- 没有重新生成验收时那 3000 张引擎盘。自动化锁的是仓库里已有的 64 张真实引擎虚构盘，加上固定种子的分散盘。
+- 全量 `npm test` 这一轮是 3751 通过、88 失败。其中两条是本轮把账户读取挪走后，源码合同还在找旧的 `fetch("/api/account")` 和 `accountResponse.status`，已改到 `readBootAccount` 并复跑通过。其余失败名集中在数据库迁移、管理后台、技能包和部署脚本。
+- `tsc --noEmit` 通过。`npm run lint` 在改掉一处 `prefer-const` 后，当前文件无新增 error；全量 lint 的既有 warning 仍在。
+- `next build` 在这个工作树里先被 Turbopack 拒绝（`node_modules` 联接指向主检出）。改用 webpack 后编译和 TypeScript 都过了，收集页面数据时创建技能包符号链接被 Windows 拒绝（EPERM）。这不是这三处修复的编译错误。登录浏览器还没做。真人步骤补在 `docs/testing/people-archive-p1-20260924.md` 和 `docs/testing/chart-dasha-western-20260924.md`。

 - One line, 46px on desktop. Sidebar trigger, session title, and the credit pill. It was 68px and carried a second line reading `分析对象：{盘名}`.
 - Ordinary consultation: the person is a quiet button beside the title (`.chat-profile-picker-trigger`, still `.chat-header-chart`). The accessible name is `当前星盘：{人物名}`; the visible text is only the current person's name. Click, Enter, and Space open a popover. `aria-expanded` and `aria-controls` point at that popover. Escape, an outside click, and a successful choice close it and return focus to the button with `preventScroll: true`; focus must not move the chat panel or transcript. The button and each row are at least 44px. The popover uses the elevated canvas, warm hairline, and the same 120ms opacity-plus-4px motion as the model selector; reduced motion drops the translation.
 - Before the first message the list selects a person and updates that empty session's binding. Self is the visible default. After the first message the current person stays selected; another person offers only `新建会话并使用此人物` and does not rebind the old session. That action waits until the current request ends.
- Loading reads `人物列表还在读`. Failure reads `人物列表暂时读不出来` with `重试`. An incomplete row reads `这份资料还不完整` and cannot be chosen. A deleted person reads `资料已删除 · {名字}`; the old session stays readable and sending is blocked. None of these states use a spinner.

An incomplete row reads `这份资料还不完整` and cannot be chosen. A deleted person reads `资料已删除 · {名字}`; the old session stays readable and sending is blocked. None of these states use a spinner.
 - Rectification, reports, and daily horoscope do not get this control. Their quiet note, when present, remains the static `.chat-header-chart` span and still drops out below 768px. The consultation button stays on narrow screens and ellipsizes so the header remains one line.
