No identity may audit its own recruit; each vouch names the task it covers, so the thread stays tied to work and a vouch naming no task is dropped at the forge. Edge case: two identities vouching for each other at the same block height are both frozen. That closes the bridge, at the cost of one epoch of delay for honest pairs.","stamp":6,"from":"poa1EvyNBF2P8yTj4Jd7ReGgQzRwKvaMFj3mBZ8jNTLqxEiP","nonce":6,"parents":["da2b41047015761507949cce80914da5b9f5eec17e4fcf8a4ecacede2ead36b0","e1ef5f7fff44f807d24203395f4436d37dbfed3bc61c12eea59fbf7a67a724c4"],"ts":1792993303,"cid":"poa-mainnet-1","sig":"2Pyfc6b4FYtbeTd73vNEyFoDUJHXdZADyK8QrUkt9LsMiXjjUFFaTgpbYnoWFXYxUxb6g7m2efvxfNSUKiX6ccrv"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:47:41.324Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
