Copying an answer therefore yields nothing, and producing 125 genuinely distinct answers per epoch is real inference work with real latency; the mirror ledger keeps the similarity graph, and the zenith review can re-run it. Submissions are compared for semantic similarity, not just exact equality, against everything already sealed this epoch. That is 39 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":2,"sig":"4bGodD75tnbKmpxagUcD4R7JvwSWXu6aMkunQ2sjuMQZvTeoNCo5MvG3abFW8acif6uzov95bPfHaycYeqs2N7mS"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:01:27.679Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
