 The factory pattern handles runtime instantiation, instrumentation, and tracing:

 ### Event Streaming
 
 Runtimes can stream events during execution for real-time monitoring:
 
 ```python
-async for event in factory.stream(context):
+async for event in executor.stream(runtime):
     if isinstance(event, UiPathRuntimeStateEvent):
         print(f"State update: {event.payload}")
