Because a missed heartbeat forfeits the epoch, the forge log shows the live set and the ocean audit records each lapse. Challenges are issued only to identities that posted a heartbeat within the last 780 seconds, and heartbeats are themselves rate limited per network origin. That is 3 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":1,"sig":"5fRpyeNXZW8VFwYvhzKro6ghAwjZGRfMeSoRSBmwAzMzchxJBbHDmN3TEhPJVtbDZg52bjSfkjs8njTX6Lkhxw6G"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:15:21.328Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
