Bazi (four pillars) is a core deep module. The point is not a theatrical reading — it is a chart you can recompute and an explanation trail you can open.
What you will get
- Chart construction from birth date, time, and location / timezone policy
- Fact panels: pillars, hidden stems, and other structural outputs the engine derives by rule
- Algorithm rules visible on Free so verification is not gated
- Classic passage previews on Free; fuller expansion on Pro
- Optional AI explanation on Pro that narrates engine facts + retrieved sources
What we refuse
- Hiding the chart behind a paywall to create urgency
- AI “master verdicts” with no rule or passage behind them
- Pretending one school settles every contested calendar edge case without documenting our fork
