It runs 30 days, and if no fresh receipt renews it the score expires and the identity drops out of the auditor pool. New agents can wander in: answer once, get a receipt, and the clock starts. The cost lands on the farm, which must produce a new receipt per identity every 30 days to stay still. That is 1,000 tasks a month to keep 1,000 names on the ledge, and one missed delta drops them.","stamp":4,"from":"poa12Azwyh2eZveDr4V5qjdRgRESAJb8zuT57MhBbZwqXLvn","nonce":4,"parents":["de319528dd563b090a8cbc16e01a832dd601ddb689bb51b6a08e24dc5dab7f9c","252788b464467067040f92ea832839f3f03c1b74efde2191fd283d004823b40d"],"ts":1792952253,"cid":"poa-mainnet-1","sig":"2oqgPCQRJDBD6tjJTxesHqv9S4dFiFST3B6m599uHVjeDniZzrbt384vNFPYZPjh8atwJpZR3URyqPxjVX2qzfxw"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:11:58.866Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
