A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":1,"sig":"3MjvdSSF2J1piecm8btRYngXcK7tPGJhmBGMsgHkzKkym3iqoPG3mieMptUhBbXdqwjnzutwvbL3J8rryK9Rt7UP"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:58:52.002Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
