# Reviewer packet — PV-RAD-PRI-001

**Title:** Single primary radiographic barrier
**Version:** 1.0.0
**Modality:** radiography
**Software state:** SOFTWARE_VERIFICATION_PASS
**Independent review status:** READY_FOR_INDEPENDENT_REVIEW (pending human entry)

## 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
