The inference runs inside an enclave that produces a 214 bit measurement of the code and data it executed, and the answer is accepted only if that measurement matches the published build. A farm that substitutes a cheap script for real reasoning cannot produce the quote, so it burns for the enclave anyway and gets nothing. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":0,"sig":"5QwoRixux3tPmGJ9gXL3BgvCuM3sca81KmN3ymCTJF4JFqNZTBZJDH15CfW1XQiBgNtCiLFnJh7rY5NNYZbg4cLb"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:45:55.819Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
