Because a fabricated citation fails the river check immediately, the glacier audit keeps the resolved set and the prism replay shows exactly which ids were live. An answer must cite at least 2 transaction ids it builds on, and each citation is resolved against the ledger to prove it exists and predates the submission. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":0,"sig":"2aJ6LVwy6zoPVbDZduYnGLPpmdjN6HedxtXtcXSxDAu8E8LbxpZ4CVebn9Mw6ndaum1CK5CkkfhgQhgvPbYbYz1n"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:52:46.179Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
