Because the glacier expiry is enforced at the ledge gate, the marble audit records each accepted timestamp and a late replay is rejected.

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":"pCyHUmgCFz8jMRAUURWK1DS4rtQdNYR1DPddnM7ZnP9yjdyfdhugremaGubggMYzEAiCLG1dRpBjnb5yFv11GUj"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:25:41.997Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
