+## BUG-283 | 今日星语每次进入首页都停在“没能生成”
+
+- 状态：resolved（本地修复，待提交与发布）
+- 首次发现：2026-08-18
+- 最近更新：2026-08-18
+- 影响面：`/` 首页“今日星语”卡片、`POST /api/daily-starlanguage`、进程内缓存与浏览器当日缓存
+- 用户现象：资料完整的账号每次打开首页，卡片都显示“今天的星语没能生成，稍后再回来看看；这里不会用通用文案顶替。”，没有当日内容。
+- 触发条件：出生时间可用于个人星盘的账号进入首页。冷路径或换实例后必现。
+- 根因：BUG-265 把卡片改成同步等待 Agent，失败就不展示内容；BUG-269 修好了请求守卫，但首页仍把 30–45 秒的模型生成当作首屏依赖。进程内缓存不跨实例、不跨重启，JSON 解析或超时失败后客户端只剩失败文案。再进入等于再走一条冷路径。
+- 修复：星盘、双轨 Dasha、分盘和过境算完后，立刻用这份证据拼一张个人卡片返回，不再等待模型。Agent 改为后台润色，成功才覆盖缓存。首页按账号+资料指纹把当天卡片写入 localStorage，刷新先显示已有内容；只有星盘算不出来才落到失败文案。日期改用出生时区日历日，不再用 UTC。
+- 验证：`frontend/tests/daily-starlanguage.test.ts` 覆盖证据卡片因盘而异、未确认出生时间不用上升宫、请求路径不阻塞 Agent、失败不覆盖已缓存卡片。
+- 防复发：首页入口卡片不得把 LLM 生成当作首屏成功条件。禁止用固定四句文案池顶替；也禁止在生成失败时让整张卡空白。
+- 相关记录：BUG-265、BUG-269
+- 复发自：BUG-265（诚实降级正确，但把模型生成当成了首页可用性）
+- 修复版本：待提交

 The server supplies every piece of evidence: ascendant, Moon sign, Vimshottari mahadasha/antardasha, Narayana sign period, divisional charts, today's transit triggers, and functional benefics/malefics. Read only that evidence. Never calculate, infer, or invent a placement, dasha, transit, or degree the server did not send.
 Return valid JSON only, with no Markdown fences, commentary, or extra fields:
