Steering, Interruption, and Pause Resume

A Pause button on a running agent makes two promises. No new step will begin until someone resumes the run, and the run's record will be kept so that it can continue.

It leaves four things unpromised. A tool call in progress may still finish. The agent's files and systems may change during the pause. An earlier approval may no longer apply on resume, and the next step may cost more.

Every control on a running agent promises less than its label suggests. What exactly should each control do, and what must the design state about the rest?
