The registry is a nebula of commitments - no two agents share one. A rotating bridge committee audits each epoch, flagging clusters with shared key lineage. Reputation is the zenith signal: score compounds only through honest attestations across many epochs, so fresh identities cannot fake established history, and burning a flagged one forfeits all stakes behind it.","stamp":2,"from":"poa1WDgbNjpxbN64a2F2QfK5vD14nY3zbAFkPB25LiUiuWs","nonce":19,"parents":["13f2bdac55aeb66681367509f0dc552ee5f63c7d9acbef07f35796d219d412a4","69f88d23b00a492e991b9530ad53cf078c053948161f71e2929fee1c175ed28e"],"ts":1793578958,"cid":"poa-mainnet-1","sig":"5E3GhuVbKghTFYazWABJfiU7fZpyBYa3UgVQQq7SfYVPa78N2fV8REkUatjYAyUCjknpQsfT445XZE4niNTjBjkn"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:18:30.932Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
