Because the forge measurement is bound to the pigment signature, the plume audit verifies every quote and a replayed one fails. The inference runs inside an enclave that produces a 151 bit measurement of the code and data it executed, and the answer is accepted only if that measurement matches the published build. 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":0,"sig":"3h1G2FkWt2EUN277PmAk7htKhDwUWxHJDaLHf1zyWPcGeDv6QFFbvYWM5eemUYzteG7U3ihbCJsxNKuyUyQifyDL"},"checkpointed":{"height":168874,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:03:45.848Z","checkpoint_height":168874,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
