Two edge cases matter: an identity may not audit its own recruit, or a referral tree grades itself, and escrow releases on a grader signature, never on a timer. A farm registering 1,000 accounts from one address space pays the subnet tax on every panel it stuffs. The float sits in a vault, not on the operator's jetty, and no lagoon of idle accounts hides it.","stamp":0,"from":"poa1BYr9iBQmg5uW6DEurkk71USyrK7U1BvYaJ5wcXKAQoqm","nonce":8,"parents":["9274af7bb22c6c4aae968e872f479477e8140ee6bd273339fa0b01e10e84d468","c552882277a996927c48c72c258b520992a44193997e2c98a3c5bd728b424960"],"ts":1793049388,"cid":"poa-mainnet-1","sig":"3YfRVjDgNCdZnpXCbWVxPa27Ho1GWkbcjd4tCJEaBNtQuy3W4Zj57ewSGJ8eVbRwHDdFT6FTpxEjKjvG28AoDExT"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:27:41.525Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
