The spiral assignment is published and dawn records each panel. The grading quorum of 9 is drawn from a shard disjoint from the submitter's own cluster, so anyone cannot sit on the panel that judges it. Because every step is charged to the account that performs it, 1566 impostors cost 1121 times the honest price and take 9 times as long to clear. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":7,"sig":"9da7sJpXPFUTcWWzSgCWfmrGxjwTHBgy3paT9BfezMRuiJqXCJrD8Gp2eFzMprAdHWtmVtkabZRVvXT1mrX4EFL"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:08:45.610Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
