 # 印度占星 Skill 更新日志
 
+## 2026-09-15 — 新增只读星历页：五要素、当日行运、九十天事件
+
+登录后可直接打开 `/ephemeris`，看当天的五要素、九曜行运（含相对本命宫位）和未来九十天的换座与停滞。不扣点、不调模型。日期可前后切换。这一页只摆天象，不写对你的判断；底部「带这天去提问」会把该日期带进对话。五要素按 Lahiri 计算，和星盘页的岁差可能不是同一套，页上有说明。换座与停滞若后端尚未上线，该段显示静态说明，其余部分照常。Skill 版本未 bump。
+
 ## 2026-09-15 — 侧栏可以打开星盘，不必先花点数等模型
 
 登录后侧栏「新建对话」下面多了「星盘」和「星历」。星盘页打开即有：印度盘（D1–D30）、基础信息、Vimshottari 与 Chara 两条大运，不扣点、不调模型。西洋盘和七政四余在计算端点可用时点亮；拿不到时那一栏说明原因，整页照常。星历入口会进 `/ephemeris`，该页尚未合入时打开是 404，这是预期。Skill 版本未 bump。

+## BUG-707 | 星历页五要素按 Lahiri，星盘页按账户岁差（默认 Raman）
+
+- 状态：investigating
+- 首次发现：2026-09-15
+- 最近更新：2026-09-15
+- 影响面：`/api/panchanga_range`、星历页五要素段、星盘页 / `/api/chart` 的账户岁差
+- 用户现象：同一账户在星盘页看到的是 Raman 盘（账户默认自 `80102459` 起已是 Raman），在星历页五要素看到的却是 Lahiri 口径。
+- 触发条件：已登录并打开 `/ephemeris`；五要素来自 `/api/panchanga_range`。请求里即使带 `ayanamsa: "raman"`，`report.calculation_policy.panchanga` 仍是 `"SwissEph Lahiri at sunrise-relative reference time"`。
+- 根因：未判定。同一现象以 BUG-703 为准，本条不另开根因。
+- 修复：本轮不修。星历页五要素段标注「这一段按 Lahiri 岁差算，和星盘页用的岁差不是同一套。」行运段走 `/api/chart`、用账户岁差，不加这句。
+- 验证：`frontend/tests/ephemeris-page.test.tsx` 锁定标注只出现在五要素段。真人清单见 `docs/testing/ephemeris-page-20260915.md`。
+- 防复发：在产品未拍板前，不得把 panchanga 默认岁差改成与 `/api/chart` 静默对齐，也不得删掉星历页这行标注。

+## 做了什么
+
+任务 1：BFF `frontend/src/app/api/ephemeris/route.ts`。登录校验、`consumeUserRequestRateLimit("ephemeris")`、出生资料只从服务端自有资料读。上游 `/api/panchanga_range`、`/api/chart`（本命上升 + 目标日正午行运）、`/api/ephemeris_events`。后者失败该字段 `unavailable`，整页仍 200。不 import 计费与 mastra。窄合同 `ephemeris-contract.ts`。
+
+任务 2：独立 route `/ephemeris`。日期条 / 五要素 / 当日行运 / 未来九十天 / 「带这天去提问」。手机五要素一张卡五行。无 spinner。让步：九十天先落 `unavailable`；提问先预填草稿再回 `/`。
+
+任务 3：五要素下标注 Lahiri 与星盘页岁差不同；行运段不加。BUG-707 `investigating`。开工时 staging 尚无 BUG-703，未让号。
+
+未改：`page.tsx`、`app-sidebar.tsx`、`scripts/**`、数据库。Skill 未 bump。

+
+地址：`https://staging.jyotisha.chat/ephemeris`（侧栏入口由星盘页那一单交付；对方合入前用这条 URL）。
+
+## A. 日期前后切换
+
+1. 打开 `/ephemeris`。
+2. **看：** 没有转圈、没有骨架、没有「正在加载」。
+3. 记下五要素（星期、月相日、月宿含第几足、瑜伽、迦那）和当日行运第一颗星的星座与度数。
+4. 点「前一天」。
+5. **看：** 五要素和行运都换了，不是同一天的数。
+6. 点「后一天」回到今天。
+7. **看：** 与步骤 3 一致。
+8. 点「今天」（若已在今天，按钮可不可点都行，但不得整页失败）。
+
+## B. 五要素随日期变化；岁差说明只在这一段
+
+1. 在今天和前一天之间切换至少一次。
+2. **看：** 月相日或月宿至少有一项不同。
+3. **看：** 五要素下方有一句「这一段按 Lahiri 岁差算，和星盘页用的岁差不是同一套。」
+4. **看：** 当日行运段没有这句。
+5. **看：** 页面没有任何运势判断（没有「适合 / 不宜 / 运势」这类话）。
+
+## C. 事件列表降级形态
+
+若 staging 上 `/api/ephemeris_events` 尚未上线：
+
+1. **看：** 「未来九十天」是静态说明「换座和停滞还没接上。这一页其余部分不受影响。」
+2. **看：** 五要素和行运仍然在，整页没有报错。
+
+若已经上线：
+
+1. **看：** 事件按日期升序。
+2. **看：** 每条只写「某星 进入 某座」或「某星 停滞转顺/转逆 · 度数」，没有含义解释。
+
+## D. 「带这天去提问」把日期带进对话
+
+1. 切到某一天（今天或前一天均可）。
+2. 点底部「带这天去提问」。
+3. **看：** 回到对话页，输入框里预填了「请按 {该日} 这一天的天象来看。」
+4. 不要发出去也可以；发出去的内容不要截进仓库。
+
+## E. 未登录
+
+1. 退出登录后打开 `/ephemeris`。
+2. **看：** 「请先登录」，可以去登录。不是转圈，也不是整页白屏。
+
+## 结论
+
+> 待填。测完写日期 + 设备 + 浏览器 + 逐条正常/有问题。
