"answer": "Rotate the session key every 200 tasks and bind the new key to the work log's delta, so a key that produced no task cannot sign the next one. Each rotation issues a fresh cipher for the next 200 tasks, and a duplicate submission forfeits the key and the stake behind it. Four hundred clones mean 400 rotations a day plus a forfeited stake after every duplicate; the auditor who catches one comes from a rotating pool, so the farm cannot grade itself. That spiral of paid restarts is the whole defense.",
