+/**
+ * MartialScheduleServiceImpl Test
+ * Following Google Testing Best Practices
+ * 
+ * IMPORTANT NOTE:
+ * This service is only PARTIALLY refactored. Most methods still use Mappers directly.
+ * Only exportSchedule() is fully delegated to ScheduleExportService.
+ * 
+ * Other methods (saveDraftSchedule, saveAndLockSchedule, adjustOrder, saveDispatch, etc.)
+ * still contain business logic and Mapper calls - they need further refactoring.
+ * 
+ * This test focuses on what IS delegated, not what SHOULD BE delegated.
