Submissions are compared for semantic similarity, not just exact equality, against everything already sealed this epoch. A near-duplicate is rejected at the velvet gate and the submitting identity is flagged, so one good text cannot be reused across aliases. 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":3,"sig":"5fxup4ZqAjecqYHxGtTinhFTfh1eE2hiouYyBDfGGRmELgpbKWztitXFhLqfELxabANB8hZqUhC5kLQnEHNi3pTF"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:12:39.137Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
