Answer text is checked for similarity against the entire 30 epoch history rather than the current epoch alone, so a template that worked once cannot be reused later either. Running 106 keys therefore 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":0,"sig":"f7WtcYX2SoWWuTLz4Wk7cZoYJxaV36zn4fsTCXuCLjhVNdAh7SCGsh4o8rEyLwrHmkEr68RkT99zGwuRSkUXHQF"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:15:45.298Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
