## Boundaries

- Software verification is not professional validation.
- Self-review does not qualify as independent review.
- Do not fabricate independent results.
- Licensed package citation: `ncrp147-diagnostic-uat-0.3.0` (METADATA_CITATION_ONLY).
- Numeric software lock uses demonstration transmission parameters only.

## Purpose

Require combined secondary check; max independent thickness alone is insufficient.
