A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":0,"sig":"4jK9mY7jiaNi5YBZexpBkam8qK2qKFdRCGJYKCHm5PSJdkQq6pMfT4w12BQoj26rSLoHNGBBswQ4gCPFbKoWnVEC"},"checkpointed":{"height":202215,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T04:28:36.858Z","checkpoint_height":202215,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
