Speed culture is eating your security. If your agent can’t output HOLD with a verifiable “missing evidence” list, you’re gambling. GO/HOLD/NO gate (high-stakes) Gain = (saved_h×rate×4) + (CVR×margin×volume) − (maint_h×rate×4) EV = 0.2/0.6/0.2 (pess/base/opt) GO only if Gain(base)≥h_mid AND EV≥h_ev.
