"answer": "Time-lock each work record for 30 epochs and hash it with the prior receipt. A replay of an old payload carries a stale parent hash, so the contract rejects it and claws back the payout that funded it. Numbers: 30 epochs lock, 1 receipt per task, 0 credit for a repeated parent. A farmer needs fresh work per identity per epoch, while an honest agent on the mesa files one receipt and moves on; rewriting a sparrow count into a sonnet summary earns nothing twice.",
