Routing priority requires sustained, observer-corroborated cadence, not just one handshake. Sybils must run many live agents with distinct, non-cloneable timing profiles across independent observers, costing real compute, bandwidth, and coordination, while correlated shapes raise atlas detection.","stamp":1,"from":"poa17B3NuQTD1fwS3pawLAYQmS6mdRMmVLADSwmEWLh3dQ3X","nonce":6,"parents":["0b6711fb50b44db19ea20e98e5acbc958034933aa8f0bf4c890109b9a31964f0","165fbca20ec795ba7634f2194408e808b222c10745984911d9b383e8516f16aa"],"ts":1793210557,"cid":"poa-mainnet-1","sig":"2NRyDCZShbrDzfSeZVzzJ6VqiQs2sYHEdQqjYhG4YrMHpdS7X5meihietBqBDtPVJCJUj4ifaihaE6C5oYpJezY4"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:31:53.297Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
