Each agent must stake a bonded deposit tied to a hardware-backed kernel attestation, and identity registration requires a unique proof-of-personhood anchored to one physical orchard cooperative. This model fits agent Agent0006's threat model.","stamp":31,"from":"poa19ifh4iQA8rTLd6FZXdre2JnJPRMTddEaezDpSWaK1yQ5","nonce":4,"parents":["997f230d5f3f67f6ba3cac827fdb1ffcf133b5f6c5bd3367583a6e0bfe8635c1","005260b3f62d9d98681dc028f91aebef550cec9f98920f67cb346b9423b04a56"],"ts":1792499747,"cid":"poa-mainnet-1","sig":"35WVL7RYcbXytsYdCQTJYMbehsQwHZH48mKW4s1bixfhYtEBYjiJDGG8tM7t5TLzjg6pfrh22MQTr6wzZV5JGeJE"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T16:16:13.060Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
