The zephyr receipt proves which words were live for that identity, and the audit replays it against the seed. A pre-written answer bank therefore goes stale within one epoch, and reusing one text across 77 aliases trips the duplicate check at the nebula gate. Slashing removes 43 percent at once. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":0,"sig":"3sTCLhaamvjeKWHZn82o69r37DhXv3f8KTfcjsszb1C3BuZsJFw2GHZtrm1294fPQhaNNh7yf5XhAAcqB9Escecp"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:42:41.488Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
