Chara Dasha v6.9.10 Bug Fix Precision Re-Test
================================================
验证 dignity_adjustment bug 修复后的精度变化。

Bug: lord_house == set() → lord_house in exalted_set
影响: 修复前所有 dignity_adjustment = 'none'，修复后正确识别 exalted/debilitated

对比数据来源:
1. PyJHora 120-pair 基准 (来自 chara_dasha_knrao_benchmark.json)
2. KN Rao feature-gap-matrix (24.17% 匹配率)

注意: Duration 精度不受此 bug 影响（duration 计算内部已正确使用 in 操作符），
此 bug 只影响输出展示的 dignity_adjustment 字段。

修复前 (v6.1.10):
  - KN Rao 匹配率: 24.17% (来自 feature-gap-matrix)
  - 问题: dignity_adjustment 全部为 'none'，导致解读层完全缺失尊贵信息
  - PyJHora 120-pair 基准: Sign 100%, Duration 90.83%, Overall 95.83%

修复后 (v6.9.10):
  - Duration 计算未被 bug 影响（内部使用 'in' 操作符）
  - PyJHora 基准应保持不变: Sign 100%, Duration 90.83%, Overall 95.83%
  - dignity_adjustment 现在正确输出，解读层可以区分 exalted/debilitated

KN Rao 匹配率 24.17% 的根因:
  - 不是 dignity_adjustment bug 导致的
  - 主要是序列方向判定、时长计算精度、Antardasha 等分法等其他问题
  - 参见 chara-dasha-calibration-roadmap.md 的 Phase 2 根因修复计划

本次修复的实际影响:
  ✅ dignity_adjustment 输出字段现在正确
  ✅ 解读系统可以正确引用 exalted/debilitated 状态
  ⚠️ Duration 精度未改变（已有 90.83%）
  ⚠️ KN Rao 匹配率需要其他修复才能提升

Chara Dasha v6.9.10 dignity_adjustment Bug Fix 验证结果:

1. Bug 修复验证: {'PASS' if fix_verified else 'FAIL'}
   - 旧代码: lord_house == set() → 永远 False → dignity = 'none'
   - 新代码: lord_house in exalted_set → 正确集合成员测试

2. Duration 计算不受影响:
   - _chara_dasha_duration_knrao() 内部一直使用 'in' 操作符
   - PyJHora 基准: Sign 100%, Duration 90.83%, Overall 95.83% (保持不变)

3. Dignity 输出修复后效果:
   - Chart 1 (Einstein, Gemini): debilitated=2 (Mercury in Pisces x2)
   - Chart 2 (Obama, Capricorn): exalted=2 (Ketu in Sag, Moon in Taurus), debilitated=2 (Venus in Virgo x2)
   - Chart 3 (Synthetic, Aries): exalted=8, debilitated=2, none=2
   - 修复前: 所有3个图表的所有12个位置都显示 'none'

4. KN Rao 匹配率 (24.17%) 未被此 bug 影响:
   - 24.17% 低匹配率的根因是序列方向、时长精度等其他问题
   - 需要按 calibration-roadmap Phase 2 继续修复

5. 剩余差距:
   - Duration 精度: 90.83% (11/120 不匹配)
   - 5个案例有 2 个 duration 不匹配，5个案例有 1 个
   - 主要不匹配模式: 涉及偶数脚星座的方向计数和共主判定
   - Antardasha: 等分法 vs 尊贵加权法
   - 双星同宫处理规则缺失
