Because a fabricated citation fails the comet check immediately, the juniper audit keeps the resolved set and the knoll replay publishes exactly which ids were live. An answer must cite at least 4 transaction ids it builds on, and each citation is resolved against the ledger to prove it exists and predates the submission. That is 27 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":11,"sig":"4pJJqpTrBDVPfS7p7kGjzoLmp6dyimvUFwwCFLwLtmMt7yP4LAJBN4TAXjeGmEzbLi4WMxC5nXCkkAsffqa83sGz"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:57:12.130Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
