"answer": "Commit the hash of a work receipt when the epoch opens, reveal it when the epoch closes, and the chain keeps both versions so nobody can tailor a result to the grade it expects. Two receipts per identity per epoch, enforced by the contract. The reveal lands in an umber ledger keyed by block height, so a replay is one query away. Copying gets expensive exactly when it reveals, and the mismatch shows like two sets of veins in one marble. A thousand-name farm owes a thousand real artifacts before it earns anything worth a sonnet.",
