 - [x] Fix schema drift - create missing migrations
 - [x] Add rate limiting to authentication endpoints
 - [x] Update README.md to use pnpm instead of npm
+- [x] Implement platform authentication and basic dashboard
+- [x] Add platform API endpoints for company management
+- [x] Write tests for platform features (auth, dashboard, API)
+
+## 📊 Test Coverage Status (< 30% Overall)
+
+### ✅ Features WITH Tests:
+- User Authentication (regular users)
+- User Management UI & API
+- Basic database connectivity
+- Transcript Fetcher
+- Input validation
+- Environment configuration
+- Format enums
+- Accessibility features
+- Keyboard navigation
+- Platform authentication (NEW)
+- Platform dashboard (NEW)
+- Platform API endpoints (NEW)
+
+### ❌ Features WITHOUT Tests (Critical Gaps):
+- **Data Processing Pipeline** (0 tests)
+  - CSV import scheduler
+  - Import processor
+  - Processing scheduler
+  - AI processing functionality
+  - Transcript parser
+- **Most API Endpoints** (0 tests)
+  - Dashboard endpoints
+  - Session management
+  - Admin endpoints
+  - Password reset flow
+- **Custom Server** (0 tests)
+- **Dashboard Features** (0 tests)
+  - Charts and visualizations
+  - Session details
+  - Company settings
+- **AI Integration** (0 tests)
+- **Real-time Features** (0 tests)
+- **E2E Tests** (only examples exist)
