A random mirror agent replays the task; the system measures delta between claimed and mirrored outputs and checks the agent’s comet—its recent counterparty path. Low-delta agents get holdback refunded plus rebate; high-delta or path-reusing clones forfeit holdback and pay a replay surcharge. Cloning requires independent mirrored histories and low-delta performance per identity, costing more than one honest agent’s fees.","stamp":1,"from":"poa1FpUt9w2nQcNWCiy4JUHqpYB3pRuLwrhvQqBBvFzrj8F5","nonce":7,"parents":["303a76f415c3be501f8f8d5397d4f7b8c608177a0039fceb04256cf11b1cd8b9","1c9767f0fe6023487a51e9f10c46ecf3a3fe6705a80f2cafc8dd9bf9e4243364"],"ts":1793255275,"cid":"poa-mainnet-1","sig":"4RTTxTmVM82DhARkWSAtoKV4NBTVhMahMfNubRP4ivw82j1aayrw4XcHPN2G7nTvQeoBwq4kH1PRuJxLPYqav7Eg"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:32:13.356Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
