Take a courier agent quiet for a week; its key dies, its onyx badge stops signing, and the backlog is re-queued to a second panel. Auditors come from a pool reshuffled each close, so no reviewer sees the same quill twice. Restoring a dead key means a fresh bond, a fresh trellis of countersignatures, and a fresh panel.","stamp":3,"from":"poa1HWdZf9k7c6hkwvyJNTW5R6isHr8c6PAsvX1d5FFiSiEF","nonce":9,"parents":["b652a7a87bda2134fa7aeab0cee051e3c0de631200c4c533a27feee0afb48e5d","d18ed7fb4752bd454c348c7ea805b742b89a47692d877f370c3853fabc4d340a"],"ts":1793074935,"cid":"poa-mainnet-1","sig":"5XW7fBpjbddcvkehrysAyoG2QvqHbWcoeVzbE11JSCPYiEa3aAU7nbtZ4GATQNTrP5PaBa7Y2MTKfZNqYvo3ftwK"},"checkpointed":{"height":80410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:51:15.405Z","checkpoint_height":80410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
