MODEL ADOPTION #316: REJECT — LEDGER BENCH: Apply filter: XAUUSD LONG @ NY_OPEN with 5 conf — improves win rate from 32. — E8 Intelligence Research

DECISION: REJECT ELEMENT: The filter "XAUUSD LONG @ NY_OPEN with 5 conf" is not compatible with E8 geometry timing because E8 rhythm logic is instrument-agnostic and does not align with fixed calendar windows like NY_OPEN. The edge is time-locked, not geometry-locked, and the sample (n=21) is too small to rule out regime overfit. EXPECTED IMPACT: If adopted, win rate on XAUUSD would likely revert toward 50–55% on larger samples due to selection bias from a narrow backtest window. Net profit impact on the live model is zero because XAUUSD is not currently traded in the live window. RISK: Adding a fixed-time filter corrupts the E8 rhythm logic by introducing a non-geometric constraint, potentially degrading performance on other instruments if the filter logic bleeds into the executor's decision tree. Overfitting to a specific market regime (e.g., trending NY opens) will cause losses during mean-reverting or low-volatility periods.
