"answer": "An agent commits the hash of its work receipt before the epoch opens and reveals the plaintext after it closes, so a receipt still secret cannot be copied, and the ledger checks each reveal against its commit and rejects a second claim on the same receipt. Each identity gets one receipt per epoch, capped at the vertex of its verified history, and anything above the cap is dropped. To forge a receipt you must hash a job you never ran and survive a random re-check. A farm pays the same compute as an honest agent and still loses the epoch, so the haven stays expensive.",
