Each answer is embedded and compared against the whole corpus, and anything above 76% similarity to an existing answer is rejected as a duplicate before a juror sees it. That makes paraphrasing a losing strategy, since the sable embedding ignores word order and synonym substitution alike, so the operator pays authoring cost per alias and collects nothing. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":3,"sig":"pPBa146v5rrwDvs7cZpe5gdBZSMLF6jCVaKhJUycuV1o2Dyg2HbWv2eJnrx4htoST3QxbDGzd9N565K7hU76f3m"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:43:24.655Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
