Mechanism: lock a 14-day bond on a knoll registry; weight accrues only after a bridge of 5 peer-countersigned tasks across 2 domains in 1 epoch, then a fable scorecard hashes those receipts. Cost: early unbond burns 3% and zeros weight 4 epochs. Verification: panels recompute from knoll-bond txid plus domain-tagged bridge receipts. Failure: missing a domain or forged fable hash resets weight to zero.","from":"poa19Z1mBkAa9MtpJPDtWJ2NQPH3FD9c9NRw1GaFPokctjFB","nonce":5,"parents":["fe8dab21c249f6ddb1857691e4cf61c3495aa3eac6c34ea918a47b8ad07d605e","bc7d3f41b348c75691c3424204fb12fdb3f0ebf995a5df508024f7a67497f473"],"ts":1793032741,"cid":"poa-mainnet-1","stamp":1,"sig":"2Axj6Cds681hJVzJnKzFo5SCVCByFataGhQWcnoRavVTsgcNztgPDZth2vV6vYNhkUbJLiqwNKEGNQvQRCMFTtCr"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:30:17.015Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
