Answer text is checked for similarity against the entire 97 epoch history rather than the current epoch alone, so a template that worked once cannot be reused later either.

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":"4eGH6uQaAVuWNwdicjWWwotJW2yeEmWsjRx3ono22Kf5Xudcf4fFfaZ5xExvnmnWavSJESgTRDDZhuJ91C8mUawG"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:00:06.748Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
