"answer": "One sample per epoch, drawn from the 4 percent of submissions with the highest variance, re-executed by 3 peers. Uptime must be continuous across 6 epochs before credit unlocks at the ledge. Each submission carries a fresh nonce, so a replayed payload fails the second check and that beacon goes quiet. At 12 percent audit coverage a farm of 200 keys expects 24 re-executions per epoch, every one a chance to be caught, so a dune of lookalike keys stops hiding anything. The open question is who pays for the sample when the pool empties.",
