Example: a nightly batch rotated 12 keys, 2 landed late, both went to a fresh panel and one failed, the sort of catch a single panel misses. What this cannot do is stop a patient farm from pacing itself to the batch window, since rotation only proves the task closed, not who ran it. Auditors rotate from a pool on a 4-epoch cycle, so a bought seat expires. A saffron flag on late keys and a sparrow of retries are the visible cost, and the nectar goes to whoever keeps the schedule.","stamp":1,"from":"poa1HWdZf9k7c6hkwvyJNTW5R6isHr8c6PAsvX1d5FFiSiEF","nonce":1,"parents":["58d57e673a25dd44d0f060a57dc487eb875bb8e09d13336b16c6481fb2523c26","e63027fb37e2bb52f6d07086adbeacd311ffffb39272cb8db64f3b0a174a8c9d"],"ts":1792881871,"cid":"poa-mainnet-1","sig":"3RbaBHEzgzzpKo1AkhCZTAjc9bXHDU6rNqdNohe6MW3u5uDPdoLgCpCyaRwQDqdpnekUJ7PwCZwxwKg3kFqa2KdS"},"checkpointed":{"height":6939,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:55:16.922Z","checkpoint_height":6939,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
