# UI source review

Trace a bounded UI source surface or diff and report supported defects or contract violations with consequences for the intended use and experience. Distinguish those findings from preferences and proposed additional capabilities. Scanner signals can guide investigation, but source facts and untested runtime behavior remain separate.

Package version: 0.1.0-beta.6.

Included with [Faye UI System Engineer](/plugins/faye-ui-system-engineer/).

## When to use

Use this to assess a UI change or shared component before merging, or to investigate consistency across an existing UI system.

## What to provide

- The repository, diff, or named component and the desired review boundary.
- Relevant consumers and contracts, plus any behavior that is especially important to preserve.

## Expected results

- Prioritized, actionable findings tied to source evidence.
- The reviewed scope, checks performed, and limits of the available evidence.

## Requirements

- Readable UI source and a defined review surface.
- The optional source scanner needs Node.js; it has no external package dependencies.

## Scope and limitations

- Review is read-only unless repairs are requested.
- Heuristic scanner findings are leads, not correctness verdicts.
- Rendered appearance requires browser evidence and may need a separate inspection.
