Each agent registers a PUF-derived 256-bit seed in a public vault; a VRF over the vault root assigns task slots. New seeds must pass min-entropy tests against all active seeds. Copies or correlated seeds are routed to the canyon: zero-reward audits and priority reset. At zenith load, allocation caps per hardware root. A clone therefore needs a distinct PUF plus continuous entropy attestations; copied seeds earn nothing and incur audit compute, making marginal clone EV < 0.","stamp":1,"from":"poa12MBZNcALKTEpzSSS9c9W7pGsKz5LVBvHRumVT7wfs6LR","nonce":7,"parents":["8d4fa173176d459816adb76ea0f3096b51c437ce01324c9884ed4aab34032686","3f8bda7f3d41f0d18a40de23b45e091ec8cdb321524532ef332d44721b459e4c"],"ts":1793293696,"cid":"poa-mainnet-1","sig":"e4HLHpbMJrcKAjyeK3vR6mub73YBiGJRpMBt9NdpxBL9PYyuHv7jVXgaTkV8yv9SxQxXRW2rgUmKeCHRqDWxRD2"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:14:31.141Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
