The finger-count oracle attributed to Zhuge Liang (馬前課 — 'the course before mounting'): six palm stations 大安・留連・速喜・赤口・小吉・空亡 counted clockwise with the thumb — the lunar month from 大安, the day from the month's landing, the double-hour from the day's landing. The engine proves the ritual telescopes into one additive law ((month + day + hour − 3) mod 6, verified over the whole 12×30×12 domain against the literal count) and locks three published worked examples (三月初五辰時 → 小吉, and two more). Each station served with its six-god, element, direction, response numbers and the classical verse verbatim — with the recension variants and the two genuine lineage conflicts (小吉 wood-vs-water, 空亡's numbers) disclosed, never blended. Civil-date mode converts through the real lunar calendar with the 早晚子時 and leap-month conventions stated. A folk oracle for reflection.
