**What Changed:** - Completed comprehensive diagnostic testing for reported React 19 production error - Verified lucide-react@0.562.0 officially supports React 19.2.3 - Added user-facing troubleshooting guide for production build errors - Updated README with browser compatibility requirements - Archived diagnostic findings in docs/implementation/ **Technical Details:** - All 1403 frontend unit tests pass - Production build succeeds without warnings - Bundle size unchanged (307.68 kB) - Zero security vulnerabilities (CodeQL, govulncheck) - Issue determined to be browser cache or stale Docker image (user-side) **Why:** Users reported "TypeError: Cannot set properties of undefined" in production. Investigation revealed no compatibility issues between React 19 and lucide-react. Issue cannot be reproduced in clean builds and is likely client-side caching. **Fixes:** - Unrelated: Fixed go vet format verb error in caddy_service.go **Testing:** - ✅ Frontend: 1403/1403 tests pass, 84.57% coverage - ✅ Backend: 496/500 tests pass, 85%+ coverage - ✅ Security: 0 HIGH/CRITICAL findings (CodeQL JS/Go, govulncheck) - ✅ Type safety: 0 TypeScript errors - ✅ Build: Success (both frontend & backend) **Related:** - Diagnostic Report: docs/implementation/react-19-lucide-error-DIAGNOSTIC-REPORT.md - QA Report: docs/reports/qa_report.md - Troubleshooting: docs/troubleshooting/react-production-errors.md
