+	// The manifestclient (input.ManagementClient) is a drop-in replacement for standard k8s clients.
+	// Pass it to your operator and run sync logic ONCE (not in a loop).
+	//
+	// Implementation steps:
+	// 1. Create operator client using input.ManagementClient (manifestclient)
+	// 2. Create informers from the manifestclient
+	// 3. Initialize the operator with these clients
+	// 4. Run sync logic ONCE (not in a control loop)
+	// 5. Return the result
+	//
+	// Example pattern:
+	//   operatorClient, dynamicInformers, err := genericoperatorclient.NewStaticPodOperatorClient(...)
+	//   if err != nil { return nil, nil, err }
+	//
+	//   // Create controllers with manifestclient-based informers
+	//   // Run sync once (not Start())
+	//   // Return result
+	//
+	// Reference implementation:
+	//   github.com/openshift/cluster-authentication-operator/pkg/cmd/mom/apply_configuration_command.go
+	//
+	// Key considerations:
+	// - Use input.ManagementClient instead of real k8s client
+	// - Use input.ManagementEventRecorder for events
+	// - Run sync ONCE, not in a loop
+	// - The manifestclient reads from input directory and writes to output directory
