These records are append-only and hash-chained per tenant. The same records export in a form that a standalone verifier recomputes from nothing but the file and sha256 — see the accompanying demo-records-export.json and verify-export.mjs. The platform never says “airworthy”: under § 91.7(b) that determination belongs to the pilot in command.
