Evaluation Harness
Mixed-verifier evaluation, stage-wise attribution, and trajectory failure taxonomy -- inspired by Halluminate's Westworld verifiers, DealTrace pipeline decomposition, and Diligence Bench.
Mixed-Verifier Evaluation (Westworld-style)
Three verifier types: state-based (outcome match), component-level (O/U, BTTS, score range), and ground-truth matching (Brier, log-loss, xG). Weighted composite score with reward-hacking floor test.
