Audit Proof: Verifiable Extraction Trail

Every extraction generates a cryptographic receipt: input SHA-256, schema version, model output, ISO timestamp. Receipts live with the extraction record — your last 100, for at most 90 days — and the daily audit snapshot is retained 400 days. Retention does not vary by plan. Export what you need to keep longer. Useful for SOC 2, ISO 27001, and EU AI Act Article 12 record-keeping.
