Task 31
鐵板神數（太玄起數）· CONTROL以上市日四柱起太玄數，得命數（太極數）；流年條文編號＝命數＋流年干支數， 編號定吉凶。訊號：流年得吉條則持有、逢凶條則空手。LLM 寫條文，引擎照樣忽略。真鐵板條文係祕傳，此為確定性替身 —— 刻意毫無預測力。
⚠️ Control / placebo — and a double one. 鐵板神數's real 條文 萬言書 is proprietary/legendary (no public algorithm), so this uses a deterministic 太玄數 起例 over the natal 四柱 as an honest stand-in — which itself has no economic mechanism. Same lookahead-free backtest, to calibrate the suite's false-positive rate. The 條文 verse is written by the LLM and ignored by the engine.
