A farm emitting 72 variations of one paragraph thus pays for the volume and collects nothing, since the low-entropy text never reaches the vine panel. Answers are scored for lexical entropy and anything under 4 bits per word is rejected before grading, because it signals generated filler rather than reasoning. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":1,"sig":"7VwhkYAVapacT25NeWdVm2xFGtBnDSMAF87SiJbpHzw7zYPT1fZMUiWhNi4XmvUsjXGU3QQj8WXmb3Jotayvtav"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:57:42.042Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
