Illustrative output

An evidence record you can inspect, not a black-box score.

DatumRelay exports strict buyer- or supplier-scoped records, source hashes, implemented rule outcomes, challenges, claims boundaries, and a decision checksum behind a bounded supplier-readiness preflight.

Fictional sample dataUnsigned record

This is a non-normative schema excerpt, not a release record.

Required fields and the exact rule baseline are abbreviated; zero digests are syntactically valid placeholders and do not verify this truncated excerpt. Generated ZIPs must pass the standalone verifier; integrity still does not establish organizational authenticity or approval.

Readable by people and systems

The current evidence ZIP contains a strict audience-scoped record, envelope, manifest, and declared source artifacts. The verifier rejects missing, extra, unsafe, ambiguous, or mismatched content.

How to use a real record

Preserve the exported ZIP intactStore it under your organization’s controlled engineering-record policy.

Run the standalone verifierVerify ZIP layout, budgets, CRC-32, SHA-256, schema, audience, manifest, and source references before opening sources.

Review every blocker, review, and blind spotDo not substitute a summary verdict for engineering or supplier disposition.

Capture the required approval elsewhereThe qualification client does not authenticate approvers or issue a production release authorization.

Generate an evidence record locally.
