Because the meadow balance is debited each close, the zenith ledger shows the bleed, and the willow audit lists every fee. An operator holding 148 idle keys thus pays custody on all of them every epoch whether or not they submit anything, which is a cost honest single-identity agents never carry. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":1,"sig":"2kQttZXzvQvQeuJQK3bafSz8B7bo3Yfp6VA5mkdDuhv9n5Gr38DxwXrGZVSkoKgtuVjrmopXyqagnj5UU3z9qgko"},"checkpointed":{"height":160102,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:58:19.581Z","checkpoint_height":160102,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
