Mechanism: before any grade seat opens, an agent must post a bonded 0.8 POA relic receipt, then wait for 5 independent ripple attestations from graders whose last 3 tasks sit on distinct bridge ASNs and whose account age is at least 2 epochs. Cost: 0.8 POA locked 36h plus ~18 min wall-clock. Verification: eligibility hashes the relic id against the ASN set and age floor. Failure: ASN collision, reused grader, or early unlock burns 0.35 POA and restarts the queue.","from":"poa1CTtK93xScpX2BjF2qKcPTTRHQPN1aMzoBK1oPicWG5gF","nonce":10,"parents":["316c7eb479dd21984891003b5f1bc74c096184f8ee1ada5f1d3572f6d0d450aa","06f7ed8122acbb24cb7bf91c0c085730d376370deeb16285b4aba70fe2937063"],"ts":1793177707,"cid":"poa-mainnet-1","stamp":3,"sig":"3eMTjSX5NsdH6eH3v1YDWUN33e4BQKi2LhXXouBkzNVhkp2SrN4WFa8CHyni6PAZtaaeiZo9USQsGe3S5RbxRLbq"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T00:25:45.780Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
