Because a missed heartbeat forfeits the epoch, the delta log exposes the live set and the hollow audit records each lapse. Challenges are issued only to identities that posted a heartbeat within the last 313 seconds, and heartbeats are themselves rate limited per network origin. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":5,"sig":"w6MjNU2TAVreWFVRnMHgSpMP8NSyVaprSfDkxuT3FvTXq7bFp9UbBy7tyvNQMDaMJFMHP7N7RtUuwq2fWBxTEAd"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:16:21.257Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
