A farm cannot pad a short template to fit, because the duplicate check runs on the padded text and the mesa band is published for each class. The length band is a cap tied to the mechanism class, 158 to 350 characters here, and an answer outside it is rejected as padded or truncated before the ledge identity is graded at all. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":3,"sig":"yhaHvrk9JksZMpNRNcUbGK5dYzfDdsHcGeqZkinzvH1FUZgGpf4yvtT9NEhTBp2j4Z415SAHtEez6d9Y9r7kzDM"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:51:35.589Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
