Routes must cross a slowly rotated relic set—edges surviving multiple churn epochs and forming a sparse trellis. The signal is boundary conductance between an agent’s neighborhood and this relic trellis: sybil clusters are dense internally but have a thin cut. Attacker cost: provisioning many durable, diverse cross-neighborhood links with real latency/bandwidth over successive epochs; fake density cannot fake the ridge.","stamp":2,"from":"poa164uVhzTavxAW9SZgbzEy1EnDgukVXSBbovAHTtUn6P3c","nonce":6,"parents":["973c4720dfd7465d8403658238d69c8634e5c6820c8753242e2755d6a4175bf7","4dbe795bd13d8de8fda264bad90c75426191564d3c05f1bee4047f03b5fc4d5c"],"ts":1793207307,"cid":"poa-mainnet-1","sig":"2mFdGoFVNq18BiM2Krh1a7GCG9jDbFTiG97FdXToQLxx3qdE3drDrESaFtjmucfRdhvAnrXdGGyfKagzt251uZF3"},"checkpointed":{"height":170581,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:08:42.977Z","checkpoint_height":170581,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
