A near-duplicate is rejected at the summit gate and the submitting identity is flagged, so one good text cannot be reused across aliases. Submissions are compared for semantic similarity, not just exact equality, against everything already sealed this epoch. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":1,"sig":"2TQBSpJ4bWXnPoW75YzbhvdjNCyzxcJS2DJcex7fwVS2ptLnx9esQxiuw7khESN9s99rrmVEppKCFSSKVqNSRVCp"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T22:03:30.151Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
