 # 印度占星 Skill 更新日志
 
+## 2026-10-28 — 只知道出生时段时，咨询出字更快
+
+- 只填了出生时段（没有精确到分钟）的人来咨询时，后台两次计算改成同时进行，每轮约快 0.3～1 秒。回答内容不变。
+- Skill 版本不变（BUG-1473，issue #128）。
+
 ## 2026-10-28 — 回答出字时页面不再整页重画
 
 - 回答逐字出来时，只有回答那一块在更新；顶栏、输入框和右侧本命盘不再每一帧跟着重画（以前最多每秒 60 次）。长回答时电脑更省力，滚动和点按更跟手。看到的内容不变。

+## BUG-1473 | 按出生时段咨询时，窗口排盘和时段读数排队串行
+
+- 状态：resolved（代码 + 回归测试；待部署）
+- 首次发现 / 最近更新：2026-10-28 / 2026-10-28（issue #118 代码体检第 11 条 → #128）
+- 影响面：只知道出生时段（没有精确出生分钟）的咨询；`frontend/src/mastra/consultation-tools.ts` `executeWindowConsultation`。
+- 现象：这类咨询每轮在出字前多等一段：先等 `/api/declared_window_chart` 回来，再发 `/api/rectification/v5/range_reading`。估每轮 0.3～1 秒。
+- 触发条件：任何按出生时段（declared birth window）走的咨询轮。
+- 根因：两个请求互不依赖，代码却先 `await` 第一个再发第二个。
+- 修复：时段读数先发出、窗口排盘随后发出，两者同时进行，再一起等结果。时段读数失败仍只是没有「分钟敏感主题」，与改前相同；窗口排盘失败时整轮照旧失败，只是此时时段读数已经发出（结果丢弃）。
+- 验证：`frontend/tests/consultation-agentic-runtime.test.ts` 新增两条：两个桩各延时 150 ms，改后总耗时 <260 ms（改前约 300 ms，改前代码上该测试失败），且窗口排盘返回前时段读数已开始；`minuteSensitiveThemes` 与改前一致。时段读数抛错时照常完成、不带分钟敏感主题。同文件既有窗口咨询测试（BUG-957 三条）全过。tsc 0、lint 0。
+- 防复发：上述测试。互不依赖的后端请求同时发。
+- 关联：BUG-957（窗口咨询预计算与缓存）。
+- 复发自：无
+- 修复版本：分支 `codex/window-consult-parallel-20261028`。
