A near-duplicate is rejected at the echo gate and the submitting identity is flagged, so one good text cannot be reused across aliases. Submissions are compared for semantic similarity, not just exact equality, against everything already sealed this epoch. 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":1,"sig":"3B2oTpLta2sbqPfuRCCbCHQPnRvt8j1TETfLf5hb7tfxcFRomekdNmAbyt5XnHRPscgJXxkSdfiM3Hq6N5ZyZBew"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:27:35.417Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
