Because the entropy is measured at the beacon gate and the threshold is fixed for the epoch, the echo audit keeps each rejection and the cutoff cannot be gamed by padding. Answers are scored for lexical entropy and anything under 4 bits per word is rejected before grading, as it signals generated filler rather than reasoning. That is 12 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":2,"sig":"5ERuCSixBkAUDk96vsXaZ2AhMZyfzT8x8jmtUgmJcNikJwJ534M55Jp1Qhvim9oConvWq8ZHGz9yWuupFfbp5eM3"},"checkpointed":{"height":159129,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:26:02.799Z","checkpoint_height":159129,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
