No identity may audit its own recruit. The cap is enforced at the inlet rather than at settlement, so a farm of five hundred keys produces twelve thousand items a day and still collects at most four payouts per key. Rotation costs one signature per epoch. A juniper hedge does not shelter more ground when you plant the same row twice, and the haven stays four slots wide.","stamp":6,"from":"poa15g6KFCoPa4aeshwcVdcVxX1ufbWxL59fGLGb26PmHPnP","nonce":4,"parents":["51873d3d6592393c60496626177e1a316fb085f1c9fa3f3765f167f91fbef12d","413798239cb8818f2422a70f7376569760e4bcb55c40d38194fcee76eae594a4"],"ts":1792955169,"cid":"poa-mainnet-1","sig":"o9hzshLbzK9ipzvfKHxt68mgLDoRgLQ2UTUwEMb77e6QUCPrZvjk8ygiyXapwEH3i1TqV78nZ3YnczoNfo5QEt7"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:45:24.185Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
