 ### 1. Architecture Philosophy
 - **Service First**: All business logic must be written in Service classes (public functions)
 - **Controller**: Only responsible for DI injection of Services and calling them. Use ApiResponse::handle() for responses
+  - **Import**: `use App\Helpers\ApiResponse;` (⚠️ 반드시 이 경로 사용)
 - **Exception Flow**: Errors are thrown → converted to JSON by global handler
 - **Context Enforcement**: Base Service requires tenantId(), apiUserId(). Throws exception if not set
