确定性六爻装卦/断法引擎 · Deterministic I Ching (Liù Yáo) hexagram engine by Yaomancy · Apache-2.0

把"起卦时刻"和"六爻"换算成一份结构化卦盘事实：干支四柱 → 装卦（纳甲 / 六亲 / 六神 / 世应 / 伏神）→ 旺衰骨架 → 用神。纯规则、零网络、可逐项回归验证。

法度：装卦遵《卜筮正宗》、断法遵《增删卜易》；神煞不进核心逻辑；不混派。引擎只负责一切"硬事实"，不含任何 AI 解读。

liuyao-engine is a deterministic engine for Liù Yáo (六爻) / coin-oracle I Ching divination. Given a cast and a timestamp it returns a fully assembled, machine-readable hexagram chart — Heavenly-Stem/Earthly-Branch four pillars, najia stem-branch attribution, six-relations, six-spirits, self/other lines, hidden lines, and wàng-shuāi (strength) — as plain Python data. No AI, no network, no I/O. Its lookup tables are cross-validated against najia and yigram-najia-rules; the calendar is double-checked against sxtwl + lunar-python. Classical terms stay in Chinese (with pinyin) — see the glossary; interpretive meanings are intentionally not translated.
