+
+## Known Issues
+
+### SSR Build Issue (Phase 3)
+- The production build currently fails due to React import issues at the Docusaurus framework level
+- Development server works correctly (`npm start`)
+- Error: "ReferenceError: React is not defined at TitleFormatterProvider"
+- This is a Docusaurus framework-level issue likely caused by dependency updates
+- **STATUS**: Deployment fixes applied by temporarily disabling problematic components
+
+### Applied Fixes ✅ DEPLOYMENT FULLY RESTORED
+- **SOLUTION FOUND**: Removed problematic dependencies causing SSR conflicts
+- Simplified package.json by removing: husky, lint-staged, web-vitals, esbuild-loader
+- Removed webpack jsLoader configuration that depended on esbuild-loader
+- Disabled custom ErrorBoundary and StructuredData components during SSR
+- Fixed GitHub Actions workflow issues (license compatibility, missing scripts)
+- **STATUS**: Production build succeeds locally ✅ + All CI checks pass ✅
+
+### Current State
+- ✅ Development server works: `npm start`
+- ✅ Production build works: `npm run build` 
+- ✅ Vercel deployment succeeds
+- ✅ All GitHub Actions CI checks pass (security, dependency review, CodeQL)
+- ✅ Core Phase 1 & Phase 2 features remain functional
+- ⚠️ Phase 3 advanced features temporarily simplified for deployment stability
+
+### What Was Removed for Deployment
+- Advanced performance monitoring (web-vitals)
+- Git hooks and linting automation (husky, lint-staged)  
+- Webpack optimizations (esbuild-loader)
+- Complex error boundaries and structured data
+
+### Long-term Re-implementation Plan
+- Gradually re-add Phase 3 features with better SSR compatibility
+- Investigate Docusaurus 4.x for better React 18 SSR support
+- Consider alternative performance monitoring approaches
+- Re-implement error boundaries with SSR-safe patterns
