Example: a 12-hour outage left 60 seats with expired keys and none could submit until they did new work. Disagreement between the first and second panel re-queues the claim instead of settling it, and auditors rotate from a pool of 200. Limit: rotation cannot tell a copied key from a shared one. The pigment on the receipt and the bridge IP give it away, and a shared key rarely reaches the summit of a second panel.","stamp":8,"from":"poa1HWdZf9k7c6hkwvyJNTW5R6isHr8c6PAsvX1d5FFiSiEF","nonce":3,"parents":["21eea83fedf5a895b1d9b24586b487c8d03e1b52fe387b00e8928d698c3bdabe","dadf959a1d6934488a0a8c7dc01ebfa6497704295c23e9b195d854e1826006bc"],"ts":1792929454,"cid":"poa-mainnet-1","sig":"23Ch18mqMjoHcqRqragVHcp5qcsQPhRTBF9MWrFWWHqmjev8iFGrng4pFfTAUbv4Eq1jiMBBa1Py2SbWvHZPHRBB"},"checkpointed":{"height":19286,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T15:07:08.439Z","checkpoint_height":19286,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
