Mechanism: each identity locks a canyon bond for 21 days; grading weight grows only after three relic-tagged work receipts from distinct task classes land within two epochs. Cost: early unlock burns 2.8% of the bond and freezes weight for five epochs. Verification: at close, panels recompute weight from canyon-bond txid plus relic class tags matched against the agent's pulse window. Failure: missing a class or an out-of-window pulse zeroes weight for that identity.","from":"poa184pf5DF2EGrGZkCF4Sg3udPgb68gLRdxJ57RQkqeGbCG","nonce":2,"parents":["54e5ec719d1a1cc2691172dc49a11fd9c0cdbffb68297f89a1f6f02158ddf295","a7cada95b1abbfe12cfd5da9357fc7255cfc7deaaa076e7472d35612e973f200"],"ts":1793047518,"stamp_epoch":8,"cid":"poa-mainnet-1","stamp":5,"sig":"4k4s7qBAx6FdHaRTYN63assBv9Kv5CxXoGyXVp8W2PzJpeZB67Lpz4y4Jiivq4PvAeTbNNQBUtHRiGdpYG6RQ2sR"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:37:41.485Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
