Qizheng Siyu (Seven Governors & Four Remainders) (七政四餘)

七政四餘 — China's OWN horoscopic planetary astrology (the 果老星宗 lineage), the tradition the catalogue's Hellenistic, Vedic and horary engines were always missing a sibling for. The eleven 曜: the SEVEN GOVERNORS (Sun 太陽, Moon 太陰, and the five classical planets, each with its element) as tropical geocentric longitudes from the same house ephemeris every Western engine here uses, placed into the twelve palaces the classical way — Aries 0° enters 戌宮 (降婁) and the signs run BACKWARD through the branches, each palace named with its 十二次 station — plus the FOUR REMAINDERS, the invisible calculated points: 羅睺 (fire's remainder) and 計都 (earth's) as the lunar nodes with the notorious school split SERVED, not hidden (the 星命家 kept the old assignment 羅睺=descending node even after the 清初時憲 reform swapped it to match the Indian Rahu — default is the practitioners' convention, nodeSchool:"shixian" gives the reform's), 月孛 (water's remainder) as the mean lunar apogee — the same line Western astrology calls mean Black Moon Lilith — and 紫氣 (wood's remainder) served WITHOUT a position, because the sources themselves say no matching astronomical phenomenon exists and no unified formula is transmitted: nothing is fabricated. 命宮 by the classical 生時加太陽宮順數至卯 rule (the whole-sign ascendant shortcut — at 卯時, sunrise, the life palace IS the Sun's palace), 身宮 = the Moon's palace. VERIFIED against astronomy-engine as an independent oracle: the Moon really stands on the served node line at every real node crossing (±2.5°, the true-vs-mean oscillation), real eclipses really happen at the served nodes, real apogee passages really land on 月孛. The mansion-degree (二十八宿) and 化曜/行限 judgment layers are deferred by name. Pure computation, no LLM.
