+description: Enforces the use of DTOs for UseCase entry points to maintain clean
+  architecture, immutability, and type safety.

+
+UseCase methods must accept DTOs (Data Transfer Objects) for input parameters instead of raw arrays or Request objects. DTOs must be located in the /src/Logic/[FeatureName]/DTO directory and should be immutable (readonly properties). This ensures decoupling between the Logic and UI layers. Simple primitive inputs (like a single ID) may be passed directly, but complex data structures require DTOs.
