research(d60): G1 stops on a production mapping mismatch (BUG-1497, BUG-1498, issue #149)

The D60 ascendant of the production classical_local mapping agrees with
PyJHora on 33 of 77 recorded times (42.9%). All 44 mismatches are 1-based
even signs and differ by exactly one sign; the repository's own vedastro
mode agrees with PyJHora on 77 of 77.

So G1 fails the 95% gate, but the cause is the production mapping rule in
scripts/varga.py, not a missing D60 signal. BUG-1498 records the
inconsistency as investigating. G2-G5 did not run and no scoring rule was
registered.

jyotishganit is not installed here and VedAstro was not called, so the
reconciliation is single-engine and says so.

+## BUG-1497 | D60 换格能不能帮生时校正，从没在已知出生时间的人身上测过
+
+- 状态：investigating
+- 首次发现 / 最近更新：2026-10-28 / 2026-10-28（issue #149，来源 #142 竞品宣传）
+- 影响面：生时校正的技法路由与对外文案。`skills/jyotish-birth-time-rectification/references/technique-routing.md` 现在写「D60 只作参考，不驱动结论」。
+- 现象：竞品宣传「证据够密时 D60 与纳迪分盘反向校准，收束时刻可以到秒」。纳迪那一半已在 BUG-1240 证伪（N3 ±10 窗口找回记录分钟 5/77，生产 25/77；N4 只换岁差 73/73 换段）；D60 这一半从未在 v5 77 例已知出生时间上检验。
+- 触发条件：用 D60 换格给候选分段打分，或对外宣称「到秒」。
+- 根因：未验证的技法被当成能力宣传；我方没有 D60 换格的评分实现，也没有对照实验。
+- 修复：（进行中）G1 已跑：生产 D60 上升与 PyJHora 只一致 33/77（42.9%），本仓 `mode='vedastro'` 的 D60 与 PyJHora 77/77。
+  失败原因是本仓生产 D60 映射本身（见 BUG-1498），不是「D60 没有信号」；G2–G5 暂缓，先把映射口径定下来再重跑 G1。结论出来前生产代码、技法路由、对外文案都不动。
+- 验证：待研究单 `docs/tasks/TASK-rectification-d60-two-way-20261028.md` 的 G1–G5 全部有结论后回填；不过门就写 `closed_by_design` 并附对外口径。
+- 防复发：研究单写死「先登记再跑、真值不可见、必须有安慰剂、负结果照写」。
+- 关联：BUG-1240、BUG-560、BUG-1090、BUG-1091。

+## BUG-1498 | 生产 D60 映射把 1-based 偶数星座整体后移一个星座
+
+- 状态：investigating
+- 首次发现 / 最近更新：2026-10-28 / 2026-10-28（issue #149，G1 三引擎对账）
+- 影响面：`scripts/varga.py::varga_map` 的 D60 分支（生产默认 `classical_local` 模式）。技法路由目前写「D60 只作参考」，不进校正打分。
+- 现象：v5 的 77 例已知出生时间里，生产 D60 上升星座与 PyJHora（traditional Parasara，from sign）只一致 33 例；其余 44 例全部差 +1 个星座，且 44 例全是 1-based 偶数星座（金牛、巨蟹、处女、天蝎、摩羯、双鱼）。本仓 `mode='vedastro'` 的 D60 映射与 PyJHora 77/77 一致。
+- 触发条件：读取生产 D60（`calc_varga(lon, 60)` 默认模式）。
+- 根因：`varga_map` 的 D60 分支是 `(si+pi)%12 if o else (si+1+pi)%12`（`o` 为 1-based 奇数星座），对 1-based 偶数星座加 1；同文件 vedastro 映射是 `(si+pi)%12`。两套内部映射不一致，外部引擎与 vedastro 那套一致。哪一套符合来源尚未裁决，不预设 classical 就是错。
+- 修复：未修。研究单红线要求生产代码零改动；要先按经典来源（BPHS / Raman）确认偶数星座是否真的从下一星座起算，再决定改映射还是改文档。
+- 验证：`docs/research/d60_two_way_results_2026_10_28.json`（77 例逐条：上升经度、两套本仓 D60、PyJHora D60、是否一致）。
+- 防复发：给 D60 补一条映射测试，锁定与外部引擎一致的规则；classical 与 vedastro 两种模式要么一致，要么在注释里写明来源差异。
+- 关联：BUG-1497。
+- 复发自：无。
+- 修复版本：未修。

+# PROGRESS · D60 换格双向对比（2026-10-28，issue #149）
+
+- 分支：`codex/rectification-d60-two-way-20261028`，基于 `origin/staging` `88a03808`（写作时 `7721aa9a`，开工时以实际 head 为准）
+- 执行：本地 Grok（Windows）；验收：Claude
+- BUG：BUG-1497 已登记为 `investigating`
+- 生产代码、冻结文件、技法路由、对外文案：**零改动**
+
+## 开工前置（已完成）
+
+| 检查 | 命令 | 结果 |
+| --- | --- | --- |
+| 开工预检 | `scripts/pre_work_check.py --remote-timeout 8 --command-timeout 45` | 退出码 1。`focused_tests` 里 `tests/test_preflight_fragment_scan.py::test_preflight_fragment_scan_reports_authority_layers_and_risk_buckets` 失败：断言 `.workbuddy/skills/jyotish-vedic-astrology` 镜像路径存在。Python 运行时、碎片扫描、外部引擎适配器、远端可见性四项通过；不把预检写成通过 |
+| 基线四个测试文件 | `tests/test_nadi_seconds_research.py`、`test_holdout_v5_schema.py`、`test_varga_resolution_research.py`、`test_repo_privacy_markers.py` | 98 passed |
+| 星历 | `python -c "import swisseph; print(swisseph.version)"` | 2.10.03 |
+| PyJHora | 导入 `jhora`，`jhora.horoscope.chart.charts` 有 `shashtyamsa_chart` | 可用 |
+| jyotishganit | `import jyotishganit` | **未安装**，G1 里记为 `blocked` |
+| v5 数据集 | `references/real_case_calibration/minute_rectification_holdout_v5.json` | 77 例，存在 |

+
+## 卡点：B 组的 D60 打分规则需要先定死
+
+任务书 §两个组 只写了「窗口内上升的 D60 格每换一次，候选分成两段；用户给出日精度事件时，按预先登记的 D60 规则给两段打分，淘汰规则与 A 组的换升判据同一套」。
+
+读了 A 组的实现（`scripts/research/probe_supply_after_six.py`）：六题来自**日期级**边界（Vimshottari / Narayana / 上升换座），答案是拿事件日期与边界日期比先后（`union_boundary_dates`、`generate_refresh_probes`、`apply_answer`）。D60 换格是**分钟级**的，一天里会换很多次；把日期级答案直接套到分钟级边界上，同一天内几乎没有区分度，会一边倒淘汰。
+
+两个可落地方案（已贴到 #149 请 Claude 定；我推荐 2）：
+
+1. **D60 当后置分段**：先跑完 A 组六题，再把幸存候选按 D60 换格切段，用日精度事件的领域—宫位映射给每段打分，只留最高分段（同分不淘汰，其余不动）。改动大，且把 nadi 研究的方法族混进来，报告里要单独解释。
+2. **D60 换格题只认同日事件**：把窗口内每次 D60 换格当一条「事件 E 在换格之前还是之后」的题；只有事件日期与换格日期同一天时才作答，没有同日事件就跳过、不淘汰。与 A 组共用 `apply_answer`，只换边界来源。改动小、口径干净、可复现；代价是可用题数取决于同日事件，报告里要给出每题实际用了几条。
+
+规则定了之后才写 `docs/research/d60_two_way_preregistration_2026_10_28.json` 并单独 commit，然后才第一次在 v5 上跑（红线 1）。
+
+## G1 三引擎 D60 对账（已跑，门不过）
+
+结果 JSON：`docs/research/d60_two_way_results_2026_10_28.json`（77 例逐条：上升经度、本仓两套 D60、PyJHora D60、是否一致）。
+
+| 引擎 | 与生产 D60 一致的例数 | 比例 |
+| --- | ---: | ---: |
+| 本仓生产 `classical_local`（默认） | 33 / 77 | 42.9% |
+| 本仓 `mode='vedastro'` | 77 / 77 | 100% |
+| PyJHora（traditional Parasara, from sign） | 作为对账基准 | — |
+| jyotishganit | `blocked`：本机未安装 | — |
+| VedAstro | `blocked`：本次没有联网调用 | — |
+
+- 差的 44 例全部是 **1-based 偶数星座**（金牛、巨蟹、处女、天蝎、摩羯、双鱼），差值恒为 +1 个星座；一致的 33 例全部是 1-based 奇数星座。
+- 根因在 `scripts/varga.py::varga_map` 的 D60 分支（`(si+pi)%12 if o else (si+1+pi)%12`），同文件的 vedastro 映射是 `(si+pi)%12`，与 PyJHora 一致。**这是生产映射的口径问题，不是「D60 没有信号」**，已登记 BUG-1498（investigating）。
+- 门要求「与至少一个外部引擎一致 ≥ 95%」，实际 42.9%（生产口径）→ **G1 判不过**，按任务书 G2–G5 全部停。没有跑任何计分，也没有据此改规则。
+
+## 还没做
+
+G2–G5、模型端到端对比、MEVG、报告：全部 `not_started`（G1 不过，按门停止）。
+
+下一步要产品/规划定：D60 映射是修 `varga.py`（改生产、要重新冻结）还是改文档承认这是另一种口径。定了之后重跑 G1；G1 过了才写 G2–G5 的先登记 JSON。
+
+## 环境缺口
+
+- `jyotishganit` 未安装；G1 的外部引擎只剩 PyJHora（门要求「与至少一个外部引擎一致 ≥95%」，仍可判）。
+- 预检的 `focused_tests` 有一条与本单无关的失败（上面已列）。
