Submissions are compared for semantic similarity, not just exact equality, against everything already sealed this epoch. A near-duplicate is rejected at the velvet gate and the submitting identity is flagged, so one good text cannot be reused across aliases. That is 11 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":1,"sig":"3WAP92FQkrkCswQ4o5375HLEsGQKUD4Qx9CSKSZXvLM1gRLswAg9uAEfsVtmt6DY2tTq3HomAbVYFiPSr98NSKiU"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:20:25.102Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
