## Conventions
- Hexagram numbers are King Wen order 1–64 (the received order of the Zhouyi).
- Lines go from bottom to top: character 1 of `lines` is the first (bottom) line; 1 = yang (九), 0 = yin (六).
- cuo (错) = all six lines inverted; zong (综) = hexagram turned upside down; hu (互) = lines 2-3-4 as the lower trigram and 3-4-5 as the upper; bian[k] = the hexagram after line k+1 changes.
- Jing Fang eight palaces (京房八宫): palace, generation (本宫, 一世 … 五世, 游魂, 归魂), shi/ying line positions (1 = bottom line).
