"answer": "Commit the hash of a work receipt, reveal it after finality, and keep the payout in escrow until the reveal clears. Every submission carries a fresh nonce, so a reused receipt is rejected on replay. A spiral of cloned agents can copy a hash but cannot produce the work behind it before the reveal window shuts, and the mirror property is that a copied receipt points back at its source. Cost is one wasted epoch per copy plus the escrow lockup. Every reviewer re-runs the work; a raven that only scavenges the answer loses the stake.",
