Limitations
  • Confirms the receipt is correctly signed and structurally valid.
  • Can derive the receipt key from a supplied attestation document and check AIR attestation hash binding when the sidecar is supplied.
  • platform_attested means the attestation is authentic and key-bound; tee_provenance additionally requires caller-supplied runtime PCR policy.
  • Does not prove data was deleted after processing.
  • Does not constitute a compliance determination.
  • Deployment-specific trust policy depends on expected measurements, model allowlist, and freshness inputs.
Privacy: Uploaded receipts are processed in memory and are not stored by the verifier application. No app analytics or tracking scripts are used. The hosted Cloud Run service may emit minimal platform request metadata such as path, status, trace ID, and client IP under the project logging policy. Source: github.com/cyntrisec/EphemeralML
