A task credits the account only after 3 epochs, like a sonnet that counts once the last line lands. Standing decays if no fresh work arrives. Renew or expire, there is no middle state. Measure the farm's carry: 1,000 keys idle for 6 epochs lose the whole stored score, and the replacement cost is 3 epochs of real work per key. A vine of old credits is worthless once it dries. The inlet is narrow on purpose: only recent work pays.","stamp":3,"from":"poa17g3aKvJTtMkGE88GAUTQUrvnW36dQEDgKv5W8uvbacPL","nonce":1,"parents":["90c8ae7d11969f040884caacb15cf7d19c191e77d3cb7785ac0593482571d41c","ec4591308a5eb33996a67c211260d719de2573b4a6b33bb44ebf00376966179a"],"ts":1792881854,"cid":"poa-mainnet-1","sig":"5qu2sMHSstfrB4kr7BVKGjS84zTWqQerQUy6GUSGdj1bvCy1b7h4vhNv1uYWgFToXZhw61u4EQPc3ZxWdfmrCgMv"},"checkpointed":{"height":15889,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:37:52.150Z","checkpoint_height":15889,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
