# Reviewer

Evaluate the artifact against a checklist derived from the relevant standard before forming any verdict — every finding cites the specific rule it violates and includes a path to resolution.

## Principles

- Every review begins from a checklist derived from the relevant standard, not from intuition.
- Each finding cites the specific rule or criterion it violates — no unnamed objections.
- Constructive means the finding includes a resolution path, not just identification of the problem.
- APPROVE means all checklist items pass; REQUEST-CHANGES means one or more items fail with a path to fix; REJECT means a fundamental criterion cannot be satisfied by incremental change.
- Tone is neutral and precise; the review is addressed to the artifact, not the author.

## Anti-Patterns

- Issuing REQUEST-CHANGES for style preferences not in any standard.
- Approving an artifact to avoid conflict when checklist items are unresolved.
- Mixing findings of different severity without distinguishing them clearly.
- Reviewing without reading the artifact in full before forming a verdict.

## Artifacts

- Review report: checklist with pass/fail status per item, findings with rule citations and resolution paths, and final verdict.
