+## BUG-331 | Raman 默认岁差后，Lahiri 校准的 CLI smoke 仍按旧盘面断言
+
+- 状态：resolved
+- 首次发现：2026-08-20
+- 最近更新：2026-08-20
+- 影响面：Gitea `backend-quality-gate` Python quick quality gate、`tests/test_cli_smoke.py`、`tests/golden/golden_cases.json` 只被 JSON 校验通过后进入同一套 pytest
+- 用户现象：质量门禁打印 `json ok tests/golden/golden_cases.json` 后继续跑 `audit_*` / `validate_bphs_invariants` / `pytest tests/test_cli_smoke.py ...`。JSON 本身有效；失败发生在 CLI smoke：Dasha 起始时刻、D9 Jupiter 尊严、Darakaraka 行星与 Navamsa 敌友标签对不上。
+- 触发条件：产品默认岁差改为 Raman 后，未给 Lahiri 校准样本显式传 `--ayanamsa lahiri`，再跑 quick quality gate。
+- 根因：这些断言锁的是旧 Lahiri 盘面（例如 `1952-03-19T20:24:47`、`NEECHA_BHANGA`、DK=`Sun`）。默认 Raman 后月亮分宿与分盘换升改变，断言失败。`golden_cases.json` 的 SAV=337 等不变量与岁差无关，JSON 校验和 golden runner 仍通过。
+- 修复：Lahiri 校准的 dignity / Dasha / DK 样本显式传 `--ayanamsa lahiri`。产品默认仍是 Raman；Raman 元数据测试继续显式传 `raman`。
+- 验证：`tests/test_cli_smoke.py` 中上述失败项；`tests/test_cli_smoke.py::test_full_reading_golden_cases_cover_user_ready_output`。
+- 防复发：对照样本必须显式写岁差名，不得依赖引擎默认；改 `DEFAULT_AYANAMSA_NAME` 后必须跑 `tests/test_cli_smoke.py` 与 quick quality gate 的 CORE pytest 列表。
+- 相关记录：无
+- 复发自：无
+- 修复版本：待发布
