But not just "consciousness" which has a bunch of problems of poor definition and epistemic inaccessibility, but "cognition" more broadly.

In this "OS" situation, aside from not even simulating a virtual body, it's not clear that the inputs available to the agent are especially tied to the agent's ongoing actions. By comparison, what you see is a function of how you move your body, head, eyes and eyelids, and "seeing" involves saccades that let you take in the multiple important parts of a scene. So I think this doesn't even have an instantiation which acts _analogously_ to being embodied.
