the mid-turn steering part is what I'm most curious about. for tool calls you can undo, steering mid-turn is just a nicer UX. but once a step in the workflow is something external and already committed (a payment call, an email sent, a phone call already ringing), can you still steer the model away from a plan it already started executing on, or does steering only work for the parts that haven't left the sandbox yet
