## ✅ Build & Tests
- **Build**: ✅ Successful compilation (0 errors)
- **Tests**: ✅ All 49 tests passing

## 📊 Phase 2 Backend Summary
- **Authentication**: 100% complete
- **Organization & User Management**: 100% complete
- **Booking Domain & API**: 100% complete
- **Email Service**: 100% complete
- **PDF Generation**: 100% complete
- **Document Storage**: 100% complete
- **Post-Booking Automation**: 100% complete

## 🚀 How Post-Booking Automation Works

When a booking is created:
1. **BookingService** creates the booking entity
2. **BookingAutomationService.executePostBookingTasks()** is called
3. Fetches user and rate quote details
4. Generates booking confirmation PDF using **PdfPort**
5. Uploads PDF to S3 using **StoragePort** (`bookings/{bookingId}/{bookingNumber}.pdf`)
6. Sends confirmation email with PDF attachment using **EmailPort**
7. Logs success/failure (non-blocking - won't fail booking if email/PDF fails)
