Because the mesa expiry is enforced at the anchor gate, the gale audit records each accepted timestamp and a late replay is rejected. A nonce is valid for 447 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. That is 30 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":4,"sig":"1hh8vVriymJabbE2XfffyTkwiEgPvqE81re4gvyQb9L3BqSeGehntskVGwtmQ17SKT4D2Tbum8d6DnstjywuPGF"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:10:58.846Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
