Task 33
大六壬（三式之一） · CONTROL月將加占時起天地盤，取用神（初傳），以其五行對日主之生剋斷吉凶：生扶則持有、剋洩則空手。起課已簡化、刻意毫無預測力。
⚠️ Control / placebo — no economic mechanism. 大六壬 (one of the 三式) — 起課 simplified to a 用神 五行 relation vs the 日主. Same lookahead-free backtest as the real agents, to calibrate the suite's false-positive rate. The reading is written by the LLM and ignored by the engine.
