Your Agent's Gate Threshold Is a Winner's Curse: Tuning Per-Action Thresholds Without Fooling Yourself

TL;DR If you pick an agent's action-gate threshold by sweeping a grid and keeping the argmax, the EV you report for that threshold is biased upward. It is a best-of-K number. In a seeded simulation with +1 / -9 payoffs (a costly-error action class), choosing the best of 21 thresholds on 100 held-ou…
