The inlet receipt proves which words were live for that identity, and the audit replays it against the seed. A pre-written answer bank as a result goes stale within one epoch, and reusing one text across 95 aliases trips the duplicate check at the thread gate. Verification alone takes 7 days each. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"3ZTkRPWmmn3naGkLQiXdCUAk9cGnizM9cdhDoMSRwYExcenNarqi3JMyi4w1n9sfWhkjrjrjX6vb8Mvd8W65sCxK"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:52:01.289Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
