Task 28
紫微斗數（四化飛星）· CONTROL以公司上市日排紫微命盤（十二宮、十四主星、五行局）， 再以四化飛星判運：當年天干的化祿／化權飛入命宮／財帛／官祿則持有，化忌飛入則空手。LLM 寫命書，引擎照樣忽略。 刻意毫無預測力 —— 正是重點。
⚠️ Control / placebo agent — no economic mechanism. 紫微斗數 casts the company's 命盤 from its listing date and trades the 四化飛星 (does the year's 化祿/化權/化忌 fly into 命宮/財帛/官祿?) through the identical lookahead-free backtest — to calibrate the suite's false-positive rate. The 命書 is written by the LLM and ignored by the engine.
