6. Verify coverage with npm run test:coverage:integration

Debugging Tests

1. Add breakpoint in VS Code
2. Run "Debug Vitest Tests"
3. Or use DEBUG=* npm run test:integration

npm run test:integration

# Check coverage
npm run test:coverage:integration

# Verify thresholds met
# Fix any failures
# Commit

Best Practices Implemented

1. ✅ Isolation: Each test creates fresh instances
