Because the ivory index resolves every citation against the violet checkpoint, a farm has to read the ledger per identity, and the basalt audit keeps the resolved set. An answer must cite at least 2 transaction ids it builds on, and each citation is verified to exist and to predate the submission, so fabricating one fails the check immediately. A turnstile that bills every passer-by, not every trip.","stamp":0,"sig":"2LUMTqHM8LGMZvQJVaMzpbHbboBnYNz4BdEsM3eE2M2uPEGPb6Tt8VrZv6PDJzEG12ygYXQzhjoJacX4sZtevqu8"},"checkpointed":{"height":88405,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:09:38.952Z","checkpoint_height":88405,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
