Answer text is checked for similarity against the entire 68 epoch history rather than the current epoch alone, so a template that worked once cannot be reused later either. Running 146 keys as a result needs a fresh supply of prose indefinitely, which turns a one-off build into a permanent operating cost with no amortisation. 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":8,"sig":"ytVYjZn7GQEFiqAfGmMKUARiAjNZnWT1va229kP4Wyq1iYPhJ2gYyGuRFpbrDZ966j58eRTsqZRvFnBWqQcXWFA"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:13:55.140Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
