732642856 62686edfa6 Release v6.0.51: fix mathibhramana 8 FNs - same_house(self) bug in expr global\n\n- Root cause: engine's same_house(a,b) has 'if a==b: return False' check.\n When L6 resolves to Mars (same planet), same_house(l6,'Mars') evaluates\n same_house('Mars','Mars') and returns False.\n- Fix: replace same_house(l6,'Mars') with direct house_of(l6)==house_of('Mars')\n in variation_2, so self-comparison still yields True.\n- Impact: mathibhramana 8 FN -> 0. Recall 91.71%->92.47% (+0.76%).\n F1 93.13%->93.54% (+0.41%). FN 87->79 (-8).\n- This is a systemic bug that may affect other rules using same_house() with\n lord-of-X patterns where the lord resolves to the compared planet. 2026-06-07 01:12:48 +08:00
732642856 ae9e00a305 Release v6.0.50: mathibhramana 294 conjunction fix (ongoing improvement) 2026-06-07 00:58:39 +08:00
732642856 d3cc37b45c Release v6.0.49: fix D9 context injection + theevrabuddhi (BVR-232); Precision 92.95%→94.69%\n\n1. D9 context injection fix (validate_logic_v2.py):\n - Bug: context was read from planet_positions_60.json (no D9 data)\n - Fix: read context from standard_test_charts.json (has full D9/Navamsa/Upagraha)\n - Impact: all D9-dependent rules can now query D9 positions\n\n2. theevrabuddhi_yoga (BVR-232):\n - Old: checked Mercury's D1 strength (completely wrong logic)\n - New: L5 benefic in D1 AND in Navamsa Lagna; D9 L1 lord benefic/aspected\n - FP: 19 → 0 (clean fix via D9 engine)\n\n3. Metrics: Precision 92.95%→94.69%, FP 73→54, F1 92.32%→93.17% 2026-06-06 23:49:03 +08:00
732642856 ab620bf130 Release v6.0.48: fix vihaga_nabhasa from wrong Sringaataka-like pattern to correct BVR-83\n\n- Fixed: old expr checked 3+ planets in 1/5/9 (Sringaataka pattern, BVR-86)\n- Correct: ALL classical planets (Sun-Saturn) occupy ONLY 4th and 10th houses (BVR-83)\n- Vihaga FPs: 5 -> 0. Precision: 92.50% -> 92.95% (78->73 FP) 2026-06-06 23:44:34 +08:00
732642856 e00f15599d Release v6.0.47: fix dharidhra FP by replacing bidirectional associated() with one-way aspect() checks
- Root cause: rel_to_any() used associated(p,o) with bidirectional aspects (aspect(p,o) OR aspect(o,p)), but PyJHora only checks one-way (trik lord -> L1, malefic -> L1, maraka -> target)
- Fixed v144/v147/v148/v149/v152 to use one-way aspect() checks matching PyJHora source
- v144: L7 aspects L1/L12 (one-way)
- v147/v148: maraka aspects L1 (one-way)
- v149: trik lord aspects L1, malefic aspects L1 (one-way, both were already correct for second part)
- v152: maraka aspects malefic in lagna (one-way)
- v145/v150/v151 were already correct (used aspect() directly)
- Corrected test expectation for chart that genuinely has dharidhra via v149
- Added proper False-no-variant-triggers test case (Cancer asc)
- Hardcoded tests: 10/10 passed
2026-06-06 22:26:55 +08:00
732642856 fffdbda22c Release v6.0.46: fix 5 completely wrong yoga rules, Precision 83.3%→92.5%, F1 87.2%→92.2%
- Fix kaalanirdesat_puthra_yoga (36→0 FPs): PyJHora 227/228 logic
- Fix sapthasankhya_sahodara_yoga (27→0 FPs): PyJHora L12+Mars+Moon+Jupiter+no Venus
- Fix sarpasaapa_yoga (25→0 FPs): PyJHora 212-215 variants
- Fix pushkala_yoga (9→0 FPs): PyJHora BVR-26 L1+Moon+dispositor
- Fix koorma_yoga (9→0 FPs): PyJHora BVR-54 method1
- Fix bhratrumooladdhanaprapti_yoga (9→0 FPs): PyJHora BVR-136
- Update hardcoded tests to match correct PyJHora logic
2026-06-06 21:54:59 +08:00
732642856 aa505ea9f7 Release v6.0.45: fix satkalatra expr (for-loop bug), add durmukha yoga, F1 0.299→0.316
- Fix bvr_satkalatra_precise: replace broken for-loop+trailing False pattern
  with any() expression. Satkalatra now detected in 4/5 benchmark charts
  (was 0/5).
- Add bvr_durmukha_yoga: PyJHora Method 1 (rasi-only), malefics in 2nd
  house + 2nd lord debilitated/conjunct malefics. Detected in 1/3 target
  charts (remaining 2 require looser PyJHora matching).
- Rules: 475→476, enabled: 404→405
- Validation: F1 0.2990→0.3160 (+5.7%), matched 74→79 (+5)
2026-06-06 21:33:32 +08:00
732642856 0003d0be88 Release v6.0.44 fix JD timezone bug in reference data
- Fix: _compute_one_chart.py JD calculation used PyJHora's
  gregorian_to_jd() which ALWAYS returns noon JD regardless of time.
  Changed to swe.julday() with correct UTC hour.
- Impact: All 60 test charts with non-noon birth times had wrong
  ascendants and house assignments (e.g. Einstein went from
  Scorpio Asc -> Gemini Asc, matching Swiss Ephemeris)
- Cross-validated: Swiss Ephemeris (industry gold standard) and
  xalen-ephemeris (Rust, 5M chart oracle test)
- New baseline: F1=93.50% (Precision=93.82%, Recall=93.18%)
- Regenerated: standard_test_charts.json, planet_positions_60.json,
  validation_logic_report.json
- Quality gate: compile/json/audit/BPHS/pytest/golden all passed

  krisanga Yoga missing return)
- Implement planet_in_house_with_aspect_or_conjunction semantic condition
- Fix lagna_lord_in_dry_sign: dry_signs set correction (Capricorn->Taurus),
  add ll_owner_dry check using dynamic co-lord resolution
- Regenerate reference data against fixed PyJHora
- F1 93.28% -> 93.76% (FN 96->86, FP 44 unchanged)

732642856 e2aa76a786 v6.0.20: Narayana Dasha (Rishi Dasha) implementation
Narayana Dasha is Parashara's rashi-based dasha system, complementary to
Vimshottari (nakshatra-based). Algorithm: start from Lagna, each sign's
dasha years = count from the sign to its lord's sign (zodiacal order).

Implementation:
- scripts/narayana_dasha.py: core calculation module
  - calc_narayana_mahadasha(): 12-sign sequence from Lagna
  - calc_narayana_antardasha(): sub-periods within each MD
  - get_current_narayana_dasha(): locate current period by age
- scripts/cmd_narayana_dasha.py: CLI subcommand
- jyotish_engine.py: Step 4.13 in full-reading + narayana-dasha subparser

Verified with Leo Asc chart: total cycle 88 years, current Sagittarius MD
(31-38 yrs, 5H/creativity) complements Vimshottari Saturn MD.

732642856 78e6f12b43 v6.0.19: fix degraded mode - Muntha no longer skipped without swisseph
Bug: v6.0.18's solar_return_full_report returned early when calc_solar_return_chart
failed (no swisseph), skipping Muntha entirely.

Fix:
- Added _estimate_sun_sign() with lookup table for sun sign from birth date
- Refactored solar_return_full_report to use degraded mode:
  - Muntha + Year Lord always computed (using lookup table sun sign)
  - Tajika/Sahams/Tri-Pataka/Mudda gracefully skipped with notes
- Added _SUN_SIGN_LOOKUP table covering 1950-2100, \u00b11 sign accuracy

732642856 0d44b9b43f v6.0.18: Solar Return/Varshaphala 实现 + Muntha covered
变更概要:
- scripts/solar_return.py(新):太阳返照盘核心计算(二分法求精确UT时刻)
- scripts/cmd_solar_return.py(新):solar-return 子命令
- scripts/jyotish_engine.py:新增 Step 4.12 + cmd_solar_return 注册 + --target-year 参数
- references/technique_registry.json:muntha→covered,新增 solar_return(covered)
- CHANGELOG.md:新增 v6.0.18 条目
- SKILL.md:版本 6.0.18

已知限制(待修复):
- swisseph 不可用时,calc_solar_return_chart 报错导致 solar_return_full_report 提前返回,Muntha 计算被跳过。
- 修复方向:将 calc_solar_return_chart 拆为 UT 计算(近似算法可用)和 chart 计算两步,chart 失败时不中断 Muntha 计算。
