## Workflow Analysis: PR Auto-Labeling

### Workflow: `pr-management.yml`

#### Documented Behavior (from COPILOT_SDLC_SUMMARY.md)
- ✅ Auto-labels PRs based on changed files
- ✅ Categorizes by area: ui, tests, docs, workflows, styling, configuration, dependencies
- ✅ Size classification: small (<50 changes), medium (<200 changes), large (≥200 changes)
- ✅ Type detection from PR title: bug, enhancement, refactor, documentation, tests, chore
- ✅ Description quality validation
- ✅ Issue linking functionality

#### Actual Implementation Verification

**File-based labeling (Lines 39-55):**
```yaml
workflows: files.some(f => f.filename.includes('.github/workflows'))
tests: files.some(f => f.filename.includes('test') || f.filename.includes('spec') || f.filename.includes('e2e'))
docs: files.some(f => f.filename.includes('README') || f.filename.includes('.md') || f.filename.includes('docs/'))
components: files.some(f => f.filename.includes('components/') || f.filename.includes('.tsx'))
styles: files.some(f => f.filename.includes('.css') || f.filename.includes('style'))
config: files.some(f => f.filename.match(/\.(json|yml|yaml|config\.(js|ts))$/))
