10 gates composing Tastytrade research (Sosnoff-Battista 2014) + Kelly criterion (Kelly 1956 + Thorp 1962 quarter-Kelly cap) + Whaley 2009 IV-rank framework + Beaver 1968 earnings IV expansion + Brier-validated personal stats via Wave-1.5 /my-options realized cohort. Each gate returns {pass, score 0-10, severity ∈ info/warn/critical}. Composite = mean of weighted scores. ANY critical gate → STAND-DOWN regardless of composite. Per Pre-Launch Validation T0: gates calibrated against Tastytrade public research; personalization activates at N ≥ 5 closed positions per strategy.
