What is Qi Men Dun Jia?
Draft — page expanding
Qi Men Dun Jia is a mystic-gate timing grid: action against hour and palace. It answers When, and Ask when the question is also a window. It is not a personality chart.
What job does it do?
When, Ask. Epistemic badge: electional.
What is traditional, and what is our interpretive layer?
Traditional mechanic, tables, and named sources live in the vault file Celestial-QiMenDunJia.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.
