Qi Men Dun Jia 奇门遁甲 — AI moment-based reading

Qi Men Dun Jia (奇门遁甲) is the Chinese strategic-divination system that casts a 9-palace board for a specific moment in time. Three layers — eight gates (八门), nine stars (九星), eight deities (八神) — rotate around the 9-palace square according to the 阳遁 / 阴遁 cycle and the 局 number (1–9). Different question categories (财运 / 事业 / 婚恋 / 疾病 / 官非 / 出行 / 考试 / 失物 / 寻人 / 合作 / 求子) draw different 用神 (significators) from the chart.

Tian Qi's Qi Men calculator runs the 置閏 plotting method by default, with 拆補 and 茅山 variants available. The AI interpreter is wired to the structured 用神 selector — given a chart and a question category, it locates the right significators and reads them.
