A random sample of settled verdicts is re-graded by an independent panel each epoch, and a divergence found on re-check costs the original grader 22% of its standing plus a seat ban. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":1,"sig":"3k1Pw5soLW6aTsasB8fwzeHzKqZ16ByX3gm3gEzfJdtCPeaGNd3f6H81T5AqvSeV6xb378jmUbTyUNSsKrhCDM7F"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:03:21.163Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
