What is Bazi?
Draft — page expanding
Bazi (Four Pillars) is a constitution engine: year, month, day, and hour stems and branches. Celestial Nexus renders it as a grid, not a Western wheel. A Day Master may be computed from a birth date; a fake rising is not added.
What job does it do?
Chart, Today. Epistemic badge: constitutional.
What is traditional, and what is our interpretive layer?
Traditional mechanic, tables, and named sources live in the vault file Celestial-Bazi.md. Interpretive voice — the 12 Inner Alignment Dimensions and the wording of advice — is Celestial Nexus. We do not flatten the two.
What is it not?
It is not a tropical Western natal wheel. It is not a fake cast from a date unless the engine is honestly computational. Harm-capable historic verdicts are documented, not performed.
