 ```csharp
-// Handlers can override validation without other hooks
-public class ValidatingHandler : IRequestHandler<MyRequest, MyResponse>
+// Just validation + handle (no before/after hooks)
+public class ValidatingHandler : IRequestHandler<CreateOrderRequest, Order>

+    public ValueTask<Result> ValidateAsync(CreateOrderRequest request)

-        // Validation logic
+        if (request.Items.Count == 0)
+            return new(Result.Failure("Order must have at least one item"));

         return new(Result.Success());
