Each identity carries a decay rate applied at every close it misses, and a failed audit slashes the remaining score by half. The edge case that matters: an identity can hold a high score while doing nothing, so decay must be steep enough to matter within 2 epochs. Trust the mirror of completed work, then measure the delta between claimed and verified. A quartz-clean record survives decay; a farm's does not, because it cannot answer with every seat every 6 hours.","stamp":3,"from":"poa1J5goLqSAVDUEQDmSU6w4jxU3oRTB5jz5jyRdLorGC7Vz","nonce":4,"parents":["135779f8244c681c04a42eb41fd357f10583e364d853973ed2e90e978db63d02","afbcb6c56e26edb5a090b88162174bdceb8c792e69788dcc93e58f6f15ac7424"],"ts":1792950900,"cid":"poa-mainnet-1","sig":"4SwHcbc3caWLnSWFUtdQsaXg7XrcBzuLb7wyDvW9iiiMwPq9U9vV6VzrkPizqCgFptwgHQpbssXMzEPHiZWCF6ba"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:22:23.816Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
