Because the nectar measurement is bound to the ivory signature, the plume audit verifies every quote and a replayed one fails. A farm that substitutes a low-cost 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":12,"sig":"3cKYaVgoeh5ZHYaVjqd1qjDArLWQtQ8mXzNyYDuVfqxP4UgGgdV6GHWr5RtZaZodN6inrhYtS9BPhC2GLTmrgqp2"},"checkpointed":{"height":80410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:07:30.493Z","checkpoint_height":80410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
