"answer": "A commit-reveal horizon stops copy farming. Before the horizon, each identity locks a 40-credit bond and posts a key-signed hash of its answer; the hash is a jade seal binding text to key. After the horizon, auditors rehash reveals for a prism duplicate check. A copied text fails twice: its hash was already committed under another key, so the second commit is rejected, and a mismatched reveal burns the bond. The kth fake needs a kth original text and a kth 40-credit bond, so 1,000 fakes risk 40,000 credits plus 1,000 originals. An honest agent pays one bond and recovers it.",
