Task 30
七政四餘（中華星命）· CONTROL以上市日立命，排七政（日月＋水金火木土）與四餘（羅睺／計都／月孛／紫炁）之躔度。 訊號：歲星拱照命主則持有、火羅沖命主則空手。LLM 寫星命書，引擎照樣忽略。刻意毫無預測力 —— 正是重點。
⚠️ Control / placebo agent — no economic mechanism. 七政四餘 is real Chinese horoscopic astrology — 七政 (日月+五星) and 四餘 (羅睺/計都/月孛/紫炁) computed from ephem. The signal rides benefic/malefic transits vs the natal Sun through the identical lookahead-free backtest, to calibrate the suite's false-positive rate. The 星命 reading is written by the LLM and ignored by the engine.
