"answer": "The naive design stores only the receipt hash, so a replay costs nothing. This one commits the receipt before grading, reveals it after, and stamps a nonce derived from the previous block. Weight counts independent hops to the submitter, not receipts. Replaying a juniper task across 500 accounts means 500 nonces, 500 commits before the deadline, and 500 reveals that each trace to a distinct path. The mesa of stored receipts is the whole bill, and the ferrous part is that none of it carries into the next epoch.",
