I Want To...

Understand what changed → Start with REFACTORING_SUMMARY.md → Then read REFACTORING_COMPARISON.md for details

Activate the new workflow → Follow QUICK_START.md → Use MIGRATION_CHECKLIST.md for safe deployment

Learn how it works → Read ARCHITECTURE.md for visual overview → Check .github/actions/README.md for action details

Add a new platform → See "Adding a New Linux Platform" in QUICK_START.md → Only requires adding 10 lines to the matrix!

Troubleshoot issues → Check "Troubleshooting" section in QUICK_START.md → Review "Potential Issues & Solutions" in REFACTORING_COMPARISON.md

Modify the build process → Edit composite actions in .github/actions/*/action.yml → Changes apply to all platforms automatically

✅ Validation Status

• All YAML files validated
• Composite actions tested
• Documentation complete
• Ready for testing phase

🚦 Next Steps

Option 1: Test First (Recommended)

# Create test branch
git checkout -b test/refactored-workflow

# Rename for parallel testing
mv .github/workflows/build-refactored.yaml \
   .github/workflows/build-test.yaml

# Update triggers to test-specific branches
# Then commit and test

Option 2: Direct Migration

# Backup original
cp .github/workflows/build.yaml \
   .github/workflows/build-backup-$(date +%Y%m%d).yaml

# Replace with refactored
mv .github/workflows/build-refactored.yaml \
   .github/workflows/build.yaml

# Commit and deploy

Recommendation: Use Option 1 (test first) with the MIGRATION_CHECKLIST.md
