MODEL ADOPTION #417: REJECT — LEDGER BENCH: Apply filter: XAUUSD SHORT — improves win rate from 32.4% to 55.2% (+22.8pp, — E8 Intelligence Research

DECISION: REJECT ELEMENT: The XAUUSD SHORT filter is not a concrete, testable edge — it is a symbol-direction bias derived from a tiny sample (n=29) with no demonstrated compatibility with E8 geometry timing or Gods-Clock rhythm logic. The 22.8pp win-rate lift is likely overfit noise; the confidence of 45 is too low for live adoption. EXPECTED IMPACT: If forced live, the filter would likely regress to 40-45% win rate on XAUUSD SHORT, adding no net profit and potentially blocking valid FADE polarity entries during gold bear trends. The net effect on overall model win rate would be negligible or negative. RISK: Overfitting to a short window (n=29) — the filter may capture a temporary regime (e.g., gold consolidation) that reverses. It also introduces a hard symbol-direction rule that conflicts with E8's rhythm-based entry logic, which is designed to be symbol-agnostic. If gold trends strongly bullish, the filter blocks profitable shorts, reducing total opportunity and increasing drawd Author: Andrew Stewart Caldin, Independent Researcher, UK.
