+### Tech Stack
+
+- **Framework**: Vite + React 18 + TypeScript
+- **Styling**: Tailwind CSS v3 + shadcn/ui CSS variables
+- **State Management**: Zustand with persistence
+- **Routing**: React Router v6
+- **API Client**: Axios with token interceptors

+### Routes Implemented
+
+| Path | Page | Auth Required |
+|------|------|---------------|
+| `/login` | LoginPage | No |
+| `/register` | RegisterPage | No |
+| `/trees` | TreeLibraryPage | Yes |
+| `/trees/:id/navigate` | TreeNavigationPage | Yes |
+| `/sessions` | SessionHistoryPage | Yes |
+| `/sessions/:id` | SessionDetailPage | Yes |
+
+### Key Features
+
+- **JWT Auth**: Automatic token refresh on 401, persistent login state
+- **Tree Library**: List/search/filter trees by category
+- **Tree Navigation**: Full decision tree traversal with:
+  - Decision/Action/Solution node rendering
+  - Path breadcrumb navigation
+  - Back button support
+  - Notes per step
+  - Session completion
+- **Session History**: View/resume sessions, filter by status
+- **Export**: Download session transcript (Markdown/Text/HTML)
+- **Error Handling**: Route-level ErrorBoundary for graceful error recovery
+
+### Frontend Bug Fixes (January 28, 2026)
+
+1. **CORS Configuration** - Added port 5174 to allowed origins in backend `.env` and `config.py`
+2. **API Response Format** - Fixed `treesApi.list()` and `sessionsApi.list()` to expect arrays (not paginated objects)
+3. **Session JSONB Serialization** - Fixed `model_dump(mode='json')` to properly serialize datetime fields for PostgreSQL JSONB storage
+4. **ErrorBoundary Component** - Added `RouteError.tsx` for route-level error handling with "Go Back" / "Go Home" buttons
+

+
+## How to Run the Frontend
+
+1. **Start the backend** (in one terminal):
+   ```bash
+   cd backend
+   venv\Scripts\activate
+   uvicorn app.main:app --reload
+   ```
+
+2. **Start the frontend** (in another terminal):
+   ```bash
+   cd frontend
+   npm install
+   npm run dev
+   ```
+
+3. **Access the app**: http://localhost:5173

 ## What's Next

-### Phase 1b: Pre-built Trees (Not Started)
+### Phase 1b: Pre-built Trees (COMPLETE - Hybrid Approach)

- Create seed data script with 5 troubleshooting trees from `TS-EXAMPLES.md`:
-  1. FSLogix Profile Issues
-  2. Citrix VDA Registration
-  3. File Share Access Problems
-  4. AD Replication Issues
-  5. Password Reset/Account Lockout
+**Seed Data Script**: `backend/scripts/seed_data.py`

-### Phase 2: Frontend (Not Started)
+**Trees Implemented**:
+1. ✅ **Password Reset/Account Lockout** - Full implementation (~15 decision nodes)
+2. 🔲 **File Share Access Problems** - Stub created (placeholder nodes)
+3. 🔲 FSLogix Profile Issues - Not started
+4. 🔲 Citrix VDA Registration - Not started
+5. 🔲 AD Replication Issues - Not started

- React application with Tailwind CSS
- Tree navigation interface
- Session management UI
- Admin panel for tree creation/editing
+**Run Seed Script**:
+```bash
+cd backend
+python -m scripts.seed_data
+```
+
+### Remaining Work
+
+1. **Testing**: End-to-end testing of full workflow
+2. **Polish**: UI refinements, error handling improvements
+3. **More Trees**: Add remaining 4 trees from `TS-EXAMPLES.md`
+4. **Deployment**: Set up CI/CD pipeline and deploy to Render/Railway

 ## Notes for Next Session

 - ✅ Backend **fully tested** - all 18 endpoints working correctly
- ✅ **Critical bugs fixed** - DateTime handling, logging, error tracking, role management
 - ✅ **Integration tests** - 29 tests with full coverage (all passing)
- ⏳ **No seed data** created yet - trees table is empty (Phase 1b)
- ⏳ **Frontend work** has not started (Phase 2)
+- ✅ **Seed script created** with Password Reset tree (full implementation)
+- ✅ **Frontend COMPLETE** - Full React app with all core pages
+- ✅ **Full workflow tested** - Register → Login → Browse → Navigate → Complete → Export all working
 - 📝 **Single-user focus** for MVP (team features are in schema but low priority)

 ### Recommended Next Steps

-1. **Phase 1b**: Create seed data script with 5 example trees from `TS-EXAMPLES.md`
-2. **Phase 2**: Begin React frontend development with Tailwind CSS
-3. **Optional**: Add more advanced logging (structured JSON logs for production)
-4. **Optional**: Set up CI/CD pipeline with automated testing
+1. **Polish UI**: Add loading states, better error messages, keyboard shortcuts
+2. **Add more trees**: Implement remaining 4 trees from `TS-EXAMPLES.md`
+3. **Deploy**: Set up CI/CD pipeline and deploy to Render/Railway
+4. **Mobile responsiveness**: Optimize for tablet/mobile use
