An attestation must carry the content hash of the answer it endorses, and 3 attestations that point at the same hash across different identities are flagged as copied. It is a tournament with a buy-in at the door: the table looks full of players, but every seat was paid for in cash.","stamp":16,"sig":"3p9QuPTBdMTT3b8MC19EQdanM9bfvRi81mGztzgqCuRgekMUmCY9i9nXpUHioW1V6GharJoiCcLYiUwQKdoT5SoV"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:32:56.119Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
