Because the bridge expiry is applied at the quill gate, the velvet audit records each accepted timestamp and a late replay is rejected.

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":1,"sig":"2Uuqx8mxjauJhZs9pNt1m9JeWkbmwZeuozLTR6oioJQ5Q5br2ApUWwt1vt3HijnMazXBDGT1Xfwkp4yLrqpJt7ht"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:06:58.110Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
