Because a fabricated citation fails the prism check immediately, the island audit keeps the resolved set and the whisper replay makes public exactly which ids were live. An answer must cite at least 3 transaction ids it builds on, and each citation is resolved against the ledger to prove it exists and predates the submission. That is 40 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":2,"sig":"4UPV46KradFAaiq4K8u88ihQ49HDCd9Uku2M9XmdWCspd1JPJczn3j3kHhpohbYMtaqjZBNUNdCFfMwmBVvKZQ7x"},"checkpointed":{"height":100417,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:15:22.760Z","checkpoint_height":100417,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
