+# MedAnnotator Frontend-Backend Integration Summary
+
+## ✅ Completed Work
+
+### Backend Enhancements
+1. **New API Endpoints Added:**
+ - `GET /datasets/{name}/annotations` - Retrieve all annotations for a dataset
+ - `POST /chat` - AI chatbot with dataset context and conversation history
+
+2. **Duplicate Handling (CRITICAL FIX):**
+ - `/datasets/load` now checks for existing annotations
+ - Filters out duplicates before inserting
+ - Returns detailed message about new vs. existing images
+ - Example: "Loaded 5 new images. 3 images already exist (skipped)."
+
+3. **New Schemas:**
+ - `GetAnnotationsResponse` - For retrieving annotations
+ - `ChatRequest` & `ChatResponse` - For AI conversation
+
+### Frontend Migration
+1. **Moved `app/` → `src/ui/`:**
+ - `app/main.py` → `src/ui/app.py`
+ - `app/components/` → `src/ui/components/`
+
+2. **Created `src/ui/api_client.py`:**
+ - Complete API client with all backend functions
+ - Error handling with streamlit UI feedback
+ - Timeout configurations per endpoint
+
+3. **API Integration Points:**
+ - ✅ Dataset loading with duplicate detection
+ - ✅ Cached annotation retrieval
+ - ✅ Export with JSON download
+ - ✅ AI chat with context
+ - ✅ Flag/Remove image actions
+ - ✅ Backend health check display
+
+4. **Smart Cache Handling:**
+ - When duplicates detected, fetches cached annotations
+ - Updates local DataFrame with backend data
+ - Syncs labels and descriptions
+ - Shows user: "Found X cached annotations"
+
+5. **Streamlit Compatibility Fixes:**
+ - Replaced `st.badge` → Custom HTML with colors
+ - Replaced `container(horizontal=True)` → `st.columns()`
+ - Replaced `width='stretch'` → `use_container_width=True`
+
+### Dependencies Added
+- `streamlit==1.41.1`
+- `pandas==2.3.3`
+- `requests` (for API calls)
+
+## 🚀 How to Use
+
+### Start the Application
+```bash
+# Terminal 1: Backend
+./run_backend.sh
+
+# Terminal 2: Frontend
+./run_frontend.sh
+```
+
+### Workflow Example
+1. **Load Dataset:**
+ - Enter folder path in "Add Files" expander
+ - Click "Confirm"
+ - Backend checks for duplicates
+ - Shows cached annotations if available
+
+2. **AI Chat:**
+ - Ask: "Can you label these images for pneumothorax?"
+ - AI responds with context from your dataset
+ - Suggests using analyze endpoint
+
+3. **Flag/Remove Images:**
+ - Use pills on each image
+ - Changes sync to backend immediately
+
+4. **Export Results:**
+ - Click "Export Results"
+ - Download JSON with all annotations
+
+## 🔧 Key Features
+
+### Duplicate Detection
+- **Problem:** Reloading same dataset caused UNIQUE constraint errors
+- **Solution:** Backend filters duplicates, frontend shows cached data
+- **Benefit:** Can reload/review datasets without errors
+
+### Cached Analysis
+- When images already exist, fetches their annotations
+- Updates UI with existing labels/descriptions
+- No need to re-annotate already processed images
+
+### AI Context Awareness
+- Chat knows about your dataset
+- Shows label distribution
+- Provides helpful suggestions
+
+## 📁 Files Modified/Created
+
+### Created:
+- `src/ui/api_client.py` - API communication layer
+- `run_frontend.sh` - Quick start script
+- `INTEGRATION_SUMMARY.md` - This file
+
+### Modified:
+- `src/api/main.py` - Added duplicate handling, 2 new endpoints
+- `src/schemas.py` - Added 3 new schemas
+- `src/ui/app.py` - Full API integration
+- `src/ui/components/image.py` - Action handlers
+- `pyproject.toml` - Added streamlit, pandas, requests
+
+## 🎯 Ready for Hackathon Demo!
+
+Your MVP now has:
+- ✅ Full backend-frontend integration
+- ✅ Smart duplicate handling
+- ✅ Cached annotation retrieval
+- ✅ AI-powered chat
+- ✅ Dataset management
+- ✅ Export capabilities
