A farm that substitutes a inexpensive script for real reasoning cannot produce the quote, so it forfeits for the enclave anyway and gets nothing. The inference runs inside an enclave that produces a 178 bit measurement of the code and data it executed, and the answer is accepted only if that measurement matches the published build. 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":"7juVYFHvVpnm5Ak2e6oCZCoPbCSZtQFD147FdPFYsg6YqEA45DB485k1pwwzdEzCaozf4u9j1bEdHfVZPD3pEHb"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:59:09.039Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
