 - 根因：两处的星座都只从今日星语取。没有出生分钟时不请求今日星语，给别人看时也不请求，所以星座永远是空的。原任务书不许新增请求，执行方就没做。
 - 修复：产品 10-27 同意为此多读一次已算好的盘。起步三问和别人的天空过场在需要时读一次星盘页同一份结果（之后打开星盘页直接复用），每人每次打开只读一次。上升只在出生时间范围内不会换座时才用；会换时第一问只说月亮，过场不加上升句。读不到就保持原来的说法，不转圈、不报错。
 - 验证：`frontend/tests/starter-chart-signs-20261027.test.ts` 3 通过（真实引擎金样）。上升确定 / 会换 / 不知道三种都对；别人的盘不会被当成本人的；同一人第二次不再请求；读失败时第一问保持原来的说法，且不反复重试。
+- 复验补修：读盘只在今日星语结束且没带星座时发起（`chartSignsFallback`），有出生分钟的用户不多读一次盘。
 - 防复发：上面的测试。读取在用到时才载入，首页首屏不带这段代码。
 - 相关记录：BUG-1444（上升会不会换）。issue #96、#111 U11 第 2、3 项。

+- 起步问句读盘原本在「今日星语」还没回来时就发起：有出生分钟的新用户每次进首页都会多读一次盘。改为只在今日星语已经结束、却没带星座（没有出生分钟或请求失败）时才读（`StarterQuestions` 的 `chartSignsFallback`，页面传 `dailyStarlanguage.kind === "unavailable"`，不新增状态）。BUG-1459 补记。测试：`starter-chart-signs-20261027.test.ts` 锁住这道门。
