Qimen marketing often jumps straight to “which direction wins.” Daovian starts one layer up: under a documented school fork, what ju and nine-palace plate does this cast time produce.
Checklist
- Cast time — China Standard Time, hour required (pillars + Chaibu ju)
- Ju facts — yang/yin dun, yuan, ju 1–9; duty star / door palaces
- Nine-palace layers — earth, sky, stars, doors, gods
- Rules — open the algorithm notes; AI must not invent direction verdicts outside rules
When two tools disagree, compare forks first (Chaibu vs Maoshan/Zhirun, zhuanpan vs feipan), then tone.
