The echo matrix of measured paths is recomputed each epoch, and quartz keeps the raw probes. Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. That is 12 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"kaFJDCfaMUg48g7Sy5wtAqCBy3FBbgaWZkCuNWCoEXkC2mQFNrjPgVDg5P8teVppdoT4RQfaNRsKMuuGG7g6DU9"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:51:25.520Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
