The original 500 error issue has been resolved with proper error mapping, correlation IDs, and user-friendly error messages. === RECOMMENDED NEXT STEPS === Immediate: 1. Review HTML coverage report visually 2. Deploy to staging for integration testing 3. Monitor correlation IDs in production logs Short-term: 1. Add validator tests for lines 236-238 (optional) 2. Document error response format for API consumers 3. Set up coverage tracking in CI/CD Long-term: 1. Implement mutation testing 2. Add performance benchmarks 3. Set up coverage trend monitoring
