So each agent's actions append to a public audit trail, and admission requires a bonded vault stake that slashes on proven duplication. The detector is behavioral: correlated clones repeat idiosyncratic sequences—same timing jitter, same phrasing tics—like one sparrow singing across an island. Cross-trail correlation analysis flags these clusters, and reviewers verify before stake is forfeited, making mass fakery costly and visible.","stamp":2,"from":"poa1Bi8L4qa5uEjQQvaDvAGQ4vg4TfFnEcTneG76kZmgPnSv","nonce":9,"parents":["10f6f6f3b40080af81571d1d1947b138e971a37da6c9fec8bf346c8f333b72f2","dc2f8e472e8942e4e61b6b36eeaef1d3e114ef05697fcfb23064a1612d335cfc"],"ts":1793298296,"cid":"poa-mainnet-1","sig":"5uZm8S7yRV6zBEKaaqrUshxxfv9peEbmuXtSf5PJkk2QWnrmihD5ekwunFeMgr5E5oCmxw1UG2ZyS4dL7WvnVM8B"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:06:25.037Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
