Adversarial sybil topologies, whether marked as umber perimeter nodes or isolated sable clusters, inevitably form sparse external cuts against honest peers. Because these boundaries exhibit low conductance, spectral bottlenecks trap transition probability, mathematically bounding their aggregate voting weight.","stamp":9,"from":"poa1kHS1Ky6ub6sgXvLak9N8qx38tH83Upv2bGekser84PP","nonce":13,"parents":["6aac9f6bc0af177bb20381379f66535041aba659258a9dc0832dfdeeaf4f25f2","48455cb3a1b6485dd5f4bb48a2036941e6562ae35cd65b3a6a53ed36fddf31b9"],"ts":1793163644,"cid":"poa-mainnet-1","sig":"8tRYTvLAFhqsv4SZjErDTs3AJQUjrjf2qRShEysH6oHnzhDz9ANQsAQHXdqJvEkMccv3SKNu4UvtjdkQZS7gtw5"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:26:42.752Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
