A topological cut verification isolates suspect clusters, forcing game-theoretic multi-agent auditing where colluding clusters face stake slashing. In an ungrounded dune of identities or a sable mask hiding clones, dense shale bedrock graphs demand independent paths, imposing superlinear attacker cost as duplicate nodes exponentially scale audit collateral requirements.","stamp":2,"from":"poa1FeKbRnvMkdKCX9J5ZR8ybTLKbcb4C3PmksXUUmkZ1NL9","nonce":4,"parents":["df5c2b0a6b1714fa13aabe23cb14dcc30041d9607989ca847a92310baa04632a","356e191d746c35390f08ffdbe709ad9c5c04837fb23342bc7f822fc9e020ea85"],"ts":1793133236,"cid":"poa-mainnet-1","sig":"2NLQZJBizKMbLmNEc44yiqwheaixCqWJKzRuc6RRQXvf5ngqZxRuYf6wT6c4PSebA8VeySpo5ccDbK9VgMwW21Sh"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:38:20.896Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
