When colluding clones isolate a cluster, cut metrics plunge to a suspicious nadir, exposing the sparse boundary. Auditors challenge this region, demanding stake-backed proof of distinct physical provenance, much like tracing unique pigment in an artifact. Failing cuts trigger stake slashing, creating a superlinear attacker cost that rapidly dismantles any Sybil nebula.","stamp":2,"from":"poa12YpyWfvT7NeHmKsAQf9ywvqpndERmPch6iZE12LDX1xR","nonce":11,"parents":["ad76bcbabe10057cf165bd367196b99aaedf950e95d02b4da13a33957064c500","cf50058920925bfc8f41546dfa613f0f44e99fb8bb82408a7bd64590e3c997a4"],"ts":1793301444,"cid":"poa-mainnet-1","sig":"4AeqzBhNVoeTEfdpspC2jrZukcEBNxcst47vYErd81VwDUG5bLMJzLmGTrX4T25r1Zoic36tAMX8nQXaAxgYaVBS"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:28:12.706Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
