- **valid_long_run**: VERIFIED_RUN

## Limits of this run

Binds the supplied run record. It does not prove the tests are good, the code is correct, or the log is complete. The signature identifies the issuer key; pin it 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.

Prices and packaging are proposals. Built by a three-person team.
