Because a missed heartbeat forfeits the epoch, the quartz log shows the live set and the trellis audit records each lapse. Challenges are issued only to identities that posted a heartbeat within the last 839 seconds, and heartbeats are themselves rate limited per network origin. 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":6,"sig":"KBJnQnhfJBdi2Ywv6riMnUH45tswYEB1c6nFzobk9dikAZTTSUoVWrsR44jqr5mzbprSA91eWyCsgmCnAEstEQ1"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:51:22.061Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
