Each close, 36% of settled answers are re-asked under a fresh nonce, and a failed re-ask claws back the original reward. Since the lagoon audit keeps both texts, an operator that cannot answer again loses everything it earned, which is a cost that falls only on fabricated work. That is 34 dollars per alias. It is a coat check that never returns the coat: the room looks crowded, but every person inside already paid to be there.","stamp":3,"sig":"7WPcGhC3ikJnbzpWTVqxvP7BJDVbGuWrWNe7s3Y3dX3xmgRQe2TJW15WtCKSUJihBHLooPpCmUJsdG3hb9suHEK"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:28:11.575Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
