+
+## QUICK FIX ROADMAP
+
+### Phase 1: CRITICAL (2-3 hours)
+These MUST be fixed for tool to work at all:
+1. ✅ Frontend npm install
+2. ✅ Frontend type definitions
+3. ✅ Database session handling
+4. ✅ WebSocket integration
+5. ✅ WebSocket thread safety
+6. ✅ Frontend env vars
+
+### Phase 2: HIGH (4-5 hours)
+These should be fixed for reliable operation:
+1. Authentication/Authorization
+2. Rate limiting
+3. Input validation
+4. Error handling
+5. Security headers
+
+### Phase 3: MEDIUM (6-8 hours)
+These improve production readiness:
+1. Database migration
+2. HTTPS/SSL
+3. Monitoring/logging
+4. Configuration management
+5. Backup strategy
+
+### Phase 4: LOW (10+ hours)
+These improve quality:
+1. Comprehensive tests
+2. Performance optimization
+3. Documentation
+4. Deployment automation

+## FILE-BY-FILE IMPACT ANALYSIS
+
+### MUST MODIFY
+```
+backend:
+  ✏️ app/api/endpoints/scans.py (high impact)
+  ✏️ app/services/scan_service.py (high impact)
+  ✏️ app/api/endpoints/websocket.py (high impact)
+  ✏️ app/scanner/port_scanner.py (high impact)
+
+frontend:
+  ✏️ src/types/api.ts (CRITICAL - type safety)
+  ✏️ .env (CRITICAL - connectivity)
+  ✏️ src/services/api.ts (medium impact)
+  ✏️ package.json (CRITICAL - dependencies)
+```
+
+### SHOULD MODIFY
+```
+backend:
+  ✏️ app/config.py (add security settings)
+  ✏️ main.py (add middleware)
+  ✏️ app/scanner/network_scanner.py (validation)
+  ✏️ app/scanner/service_detector.py (error handling)
+```
+
+### SHOULD CREATE
+```
+✨ frontend/.env (environment variables)
+✨ frontend/.env.example (template)
+✨ app/middleware/security.py (security headers)
+✨ app/middleware/ratelimit.py (rate limiting)
+✨ app/security/auth.py (authentication)
+```
+
+---
+
+## TESTING VALIDATION
+
+After implementing fixes, verify with:
+
+```bash
+# Backend Tests
+✅ Database initialization
+✅ API starts without errors
+✅ Scan can be started
+✅ WebSocket connection established
+✅ Real-time updates received
+✅ Multiple concurrent scans work
+
+# Frontend Tests
+✅ npm install succeeds
+✅ TypeScript compiles without errors
+✅ npm run build completes
+✅ Page loads in browser
+✅ Can start scan from UI
+✅ Real-time progress displayed
+✅ Results render correctly
+```

+## REFERENCE: Backend Models
+
+### Current Models
+- `Scan`: Scan operations
+- `Host`: Discovered hosts
+- `Service`: Open ports/services
+- `Connection`: Host relationships
+
+### Missing Models
+- `User`: Authentication
+- `ScanTemplate`: Saved scan configs
+- `Notification`: Alerts
+- `Audit`: Security logging
+
+---
+
+## NOTES FOR DEVELOPER
+
+1. **Database Session Pattern**: Always create fresh sessions for background tasks
+2. **WebSocket Design**: Broadcast events from central manager
+3. **Type Safety**: Ensure frontend types match backend response schemas
+4. **Async/Await**: Be careful mixing sync/async code
+5. **Error Messages**: User-friendly, not technical dumps
+6. **Security First**: Validate all inputs, check permissions
+7. **Logging**: Log actions for security/debugging
