### Backend Integration

#### API Endpoints Connected
**Authentication**:
- ✅ `POST /api/auth/register` - User registration
- ✅ `POST /api/auth/login` - User login
- ✅ `GET /api/auth/profile` - Get user profile

**Elections**:
- ✅ `GET /api/elections/active` - Get active elections
- ✅ `GET /api/elections/upcoming` - Get upcoming elections
- ✅ `GET /api/elections/completed` - Get completed elections
- ✅ `GET /api/elections/{id}` - Get election details
- ✅ `GET /api/elections/{id}/candidates` - Get candidates
- ✅ `GET /api/elections/{id}/results` - Get results

**Votes**:
- ✅ `POST /api/votes` - Submit vote

## Security Implementation

### Implemented ✅
- JWT token-based authentication
- Password hashing with bcrypt (backend)
- Token expiration (30 minutes default)
- Secure token storage in localStorage
- Environment-based API URL configuration
- CORS middleware configured
- Password strength requirements (8+ chars, uppercase, number, special char)
- Form field validation with Zod

### Recommended for Production ⚠️
- [ ] Use HttpOnly cookies instead of localStorage
- [ ] Implement refresh token rotation
- [ ] Add rate limiting on auth endpoints
- [ ] Implement password reset flow
- [ ] Enable HTTPS on all connections
- [ ] Restrict CORS to frontend domain only
- [ ] Add request signing/verification
- [ ] Implement audit logging
- [ ] Add IP whitelisting
- [ ] Set up monitoring and alerts

---

## Testing Workflow

### Manual Testing Steps
```bash
# 1. Start Backend
cd /home/sorti/projects/CIA/e-voting-system
poetry shell
uvicorn backend.main:app --reload

# 2. Start Frontend
cd frontend
npm run dev

# 3. Test in Browser (http://localhost:3000)
# - Register new user
# - Login with credentials
# - View dashboard (should show elections)
# - Logout (should redirect to home)
# - Test form validation errors
```

### Test Cases
- [ ] Registration with invalid email
- [ ] Registration with weak password
- [ ] Login with wrong password
- [ ] Dashboard loads without authentication (should redirect)
- [ ] Dashboard shows user name in header
- [ ] Election data loads on dashboard
- [ ] Logout clears session and redirects
- [ ] Protected routes redirect to login when not authenticated
- [ ] Form validation shows inline errors
- [ ] Password confirmation mismatch detected

## Performance Metrics

### Build Time
- Compilation: 1.9-4.1 seconds
- Full build: 5-10 seconds
- Development server start: ~3 seconds

### Bundle Sizes
- Shared JavaScript: 102 kB
- Home page: 105 kB First Load
- Auth pages: 145 kB First Load (includes Zod + React Hook Form)
- Dashboard pages: 113-117 kB First Load
- Per-page markup: 2-4 kB

### Network
- API latency: ~50-100ms (local)
- Token expiration: 30 minutes
- Session persistence: Browser localStorage

---

## Validation & Type Safety

### Form Validation Schemas
```typescript
loginSchema              // email, password
registerSchema          // firstName, lastName, email, password (8+ chars, upper, digit, special)
profileUpdateSchema     // All user fields with optional address/phone
passwordChangeSchema    // Current password + new password confirmation
voteSubmissionSchema    // Election ID + candidate selection
```

### Type Safety Guarantees
- ✅ All API responses typed
- ✅ All form data typed
- ✅ Zero use of `any` type
- ✅ React Hook Form fully typed with Zod
- ✅ Full TypeScript support throughout

---

## What's Working ✅
