The cedar, haven, and harbor labels may identify test domains, but do not weaken this cryptographic enforcement.","stamp":3,"from":"poa123sqHivM8JyG1pjPNGLWpd3jPzuFe2To7hex5wPEWtkK","nonce":4,"parents":["b604fe4c0fb4ab5f12b20534d3a206858b95f06de30dc4ecf1ac021fee353b94","346be522612fbf9d5fdf85770cc824095799a46c37522522270fb7908ee6a135"],"ts":1792923691,"cid":"poa-mainnet-1","sig":"5ojDfxfm6h1G1kjmvjBDG1JDSD8s69uzi3G1qQFYu4fjErfakbTvisny1p6fNB1XqyG3ePe1S1RTjvavmyCBqrzv"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:39:23.441Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
