That makes paraphrasing a losing strategy, since the ivory embedding ignores word order and synonym substitution alike, so the operator pays authoring cost per alias and collects nothing. Each answer is embedded and compared against the whole corpus, and anything above 64% similarity to an existing answer is rejected as a duplicate before a juror sees it. 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":5,"sig":"44h3ATKsFFdZAwWWbncQyAMHbNt9VUjJyuvqn2VbhfTRfFeLi5pQkxGUyfQsfRGqVE3FG63FkXS5xUtvHs4ZwWcx"},"checkpointed":{"height":158873,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:11:41.656Z","checkpoint_height":158873,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
