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):
