fix(special-lagnas): compute eight birth points without PyJHora

Production images do not install PyJHora, so those eight points were blocked.
Swiss Ephemeris now computes them in-process. Rectification keeps the old
Hora and Ghati formulas.

BUG-1273.

+- 最近更新：2026-10-08
+- 影响面：全盘、报告和对话卡里的 Bhava、Hora、Ghati、Vighati、Sree、Indu、Pranapada、Varnada。生时校正打分不走这条路径
+- 用户现象：staging `2df6ee72` 上这些点不显示。生产环境因此暂时没有这八个点
+- 触发条件：镜像只装 `requirements.txt`（没有 PyJHora）时计算特殊上升点
+- 根因：BUG-1265 的修复在有经纬度时调用 PyJHora。PyJHora 在 `requirements-reference-engines.txt`，许可证是 AGPL，不能进生产镜像。验收机装了 PyJHora，门禁 `.venv` 和生产镜像都没有。复发类型：验收环境与生产不一致
+- 修复：八个点改由 Swiss Ephemeris 在本进程计算，日出用出生地经纬度和请求的岁差。`source` 为 `native_special_lagna`。PyJHora 4.8.7 只用来离线冻结对照答案。运行时的 `calculate_pyjhora_special_lagnas` 已删除。生时校正仍调用原来的 Hora / Ghati / Bhava 公式，不升算法身份。Tajika 的进程内 PyJHora 打分和校正三引擎对照里的 PyJHora 列，分别挪到文件名含 pyjhora 的参考模块，默认全盘不调用

+# PROGRESS · 特殊上升点改为本仓原生计算（2026-10-08）
+
+执行分支 `codex/special-lagnas-native-20261008`。工作树从当时的 `origin/staging` `fe833b35` 拉出（任务书写的基线是 `c04786f7`，其后 staging 又有纯文档提交）。状态：待验收。未上线。
+
+## 做了什么
+
+- 八个特殊上升点在有经纬度时改由 Swiss Ephemeris 计算，`source` 为 `native_special_lagna`。日出用出生地经纬度和请求的岁差，算完恢复原来的岁差。
+- 公式按本仓已引用的出处：P.V.R. Narasimha Rao《Vedic Astrology: An Integrated Approach》§5.2（Bhava 0.25°/分、Hora 0.5°/分、Ghati 1.25°/分、Vighati 15°/分），Sree 为月亮在星宿内剩余度数乘 27 再加上升，Indu 与 Varnada 用 B.V. Raman。没有把「一宫每一 vighati」写成 75°/分。`references/` 里没有 BPHS 第 4 章原文，八点都有上述具名出处，没有写 blocked。
+- 运行时删除 `calculate_pyjhora_special_lagnas`。PyJHora 4.8.7 只离线生成 `tests/fixtures/special_lagnas_pyjhora_487.json`。生成命令：`python scripts/research/freeze_special_lagnas_pyjhora_fixture.py`。
+- 缺坐标时仍用原来的 Bhava / Hora / Ghati 公式。生时校正继续调用这三个函数，算法身份不升。
+- Tajika 的进程内 PyJHora 打分、校正三引擎对照的 PyJHora 列，分别挪到 `scripts/pyjhora_panchavargiya_reference.py` 和 `scripts/pyjhora_rectification_d1_reference.py`。默认全盘不调用它们。
+- 快速门增加 `tests/test_runtime_jhora_import_scan.py`。
+
+## 对照
+
+三张公开或虚构盘 × Lahiri、Raman × 八个点，相对冻结的 PyJHora 4.8.7，最大绝对差 4.9e-5°。Hora 与 Ghati 度数不同。公开盘 Lahiri 的 Bhava / Hora / Ghati 仍是狮子 17.12°、水瓶 22.58°、处女 8.94°。
+
+## 本机验证

+| --- | --- |
+| ruff（本轮改过的 Python 文件） | 通过 |
+| py_compile（本轮改过的模块） | 通过 |
+| `test_runtime_jhora_import_scan.py`、`test_special_lagnas_birth_instant.py`（不含全盘那条）、`test_rectification_three_engine_packet.py` | 18 通过 |
+| 屏蔽 `jhora` 后的 `cmd_full_reading`，加上三引擎包测试 | 5 通过；八点 `computed`，`source` 为 `native_special_lagna` |
+| 隐私扫描 `tests/test_repo_privacy_markers.py` | 通过 |
+
+未跑、不能写成通过：没有 PyJHora 的门禁虚拟环境（本机 Anaconda 装了 PyJHora 4.8.7，测试是屏蔽导入）；Linux 全量 pytest 相对 62 条基线；快速门整段（含 npm test 与 turbopack 构建）；部署后的 `/api/health`、`/login`、未登录 `/api/account`。
+
+## 开工预检
+
+`python scripts/pre_work_check.py --remote-timeout 8 --command-timeout 45` 在本工作树跑完。远端可见性已核对，外部引擎适配器诊断通过，Python 运行时通过。碎片扫描在 90 秒超时，聚焦测试在 45 秒超时。不把这次退出当成通过，也没有改断言或补 `.workbuddy` 镜像。
+
+## 偏离
+
+- 导入扫描会走到 `jyotish_api_server` 再走到校正三引擎包。那里的 `import_module("jhora...")` 挪进 pyjhora 文件名的参考模块，包函数 `_pyjhora_d1` 仍在原处，现有测试照旧替换它。
+- 全盘年运段仍会按需导入 `annual_pyjhora_replay`（文件名含 pyjhora，扫描不进入）。导入失败时该段记 blocked，不挡八个特殊上升点。

+
+Numeric rates are the ones named by P.V.R. Narasimha Rao, *Vedic Astrology:
+An Integrated Approach*, section 5.2, and by the B.V. Raman methods below.
+``references/`` does not contain the BPHS chapter 4 verse text, so a point is
+not given a rate that those named sources do not state.
+
+- Bhava: section 5.2 step (2) divides the sunrise-to-birth minutes by 4
+  (0.25 degree per minute) and adds that to the sidereal Sun at sunrise.
+- Hora: 0.5 degree per minute, one rasi per hour, from that same sunrise Sun.
+- Ghati: 1.25 degrees per minute, one rasi per 24-minute ghati.
+- Vighati: 15 degrees per minute. A literal "one rasi per vighati" (24 seconds)
+  would be 75 degrees per minute; section 5.2's special-ascendant family, as
+  recorded for this rate, uses 15. That is the frozen comparison rate.
+- Sree: ascendant plus the Moon's leftover degrees inside its nakshatra,
+  times 27 (classical Sri Lagna).
+- Indu: B.V. Raman. Kala factors of the 9th lords from Lagna and from the Moon
+  are 30, 16, 6, 8, 10, 12, 1 for Sun through Saturn. The degree is the Moon's
+  degree inside its own sign.
+- Pranapada: ishta ghatis from sunrise (previous sunrise when birth is earlier),
+  times 4 signs, plus the birth Sun, plus 8 signs for a fixed Sun sign, 4 for
+  a dual Sun sign, and 0 for a movable Sun sign. The clock is truncated to
+  whole seconds before the ghati count, matching the frozen comparison.
+- Varnada: B.V. Raman method 1. Odd signs are counted forward from Aries, even
+  signs backward from Pisces. The returned degree is the ascendant's degree
+  inside its own sign, placed in the Varnada sign.
+
+Sunrise is the centre of the solar disc, Hindu rising, no refraction
+(Swiss Ephemeris). Sidereal mode is the caller's ayanamsa and is restored.
