+## VERIFICATION PROCEDURES
+
+### Backend Verification
+```bash
+# 1. Check Python syntax
+python -m py_compile app/**/*.py
+

+python -c "from app.database import init_db; init_db()"
+
+# 3. Test basic functionality
+cd tests && pytest test_basic.py -v
+
+# 4. Start server
+python main.py
+# Should see: "Uvicorn running on http://0.0.0.0:8000"
+```
+
+### Frontend Verification
+```bash
+# 1. Install dependencies
+cd frontend && npm install
+# Should complete without major errors
+
+# 2. Check TypeScript compilation
+npm run build
+# Should complete successfully
+
+# 3. Start dev server
+npm run dev
+# Should start without errors
+```
+
+### Integration Verification
+```bash
+# 1. Backend running
+curl http://localhost:8000/health
+# Should return: {"status": "healthy", "version": "1.0.0"}
+
+# 2. API accessible
+curl http://localhost:8000/api/scans
+# Should return: [] or list of scans
+
+# 3. WebSocket accessible
+# Check browser console - should connect successfully
+
+# 4. Start a scan
+curl -X POST http://localhost:8000/api/scans/start \
+  -H "Content-Type: application/json" \
+  -d '{"network_range": "192.168.1.0/24", "scan_type": "quick"}'
+# Should return: {"scan_id": 1, "message": "...", "status": "pending"}
