## Limits of this run

Reviews the fast-path record. It does not call the model, prove its output is correct, or prove a sampled audit caught every issue. The run is Ed25519-signed; pin the issuer key out of band.

This is a bounded run on a sample. It is not an assessment of any production system, not a
certification, and not a signed attestation. The accompanying `manifest.json` records SHA-256
hashes so a recipient can detect a changed file. The manifest is not a signature and not an
attestation; it does not prove who produced the artifact.

## What this is not

- Not a vendor integration, partnership or endorsement.
- Not legal, tax, clinical, insurance or safety advice.
- Not a third-party audit, SOC 2 report, ISO certification or patent filing.
- Not a production write action: no downstream tool was called.
