Does “As normal” mean that noticing the effects of the zombie fairy results in electrochemical changes in the brain that are different from those which occur in the absence of noticing those effects?
For some reason I can understand it better if I think of a sentient computer with standard input devices as things that it considers “real”, and a debugger that reads and alters memory states at will, outside the loop of what the machine can know. Assuming that such a system could be self-aware in the same sense that I think I am, how would it respond if every time it asked a class of question, the answer was modified by ‘magic’?

...yes? How would one notice something without changing brain-state to reflect that?

I think you may have misunderstood. The fairy controls the bodies, but has perfectly predicted in advance what the human would have done. Thus whatever they try to do is simultaneously achieved by the fairy; but they have no effect on their bodies. The fairy doesn’t alter their brains at all. If something else did alter their brain, but for some reason the fairy didn’t notice and update her predictions, then they would become “out of sync” with their body.

Brain state is in principle detectable. If the fairy changes brain state, the fairy is detectable by physical means and thus physical.
Oh, I see. Yes, the fairy is physical; the brains, however, could in principle be epiphenomenal (although they aren’t, in this example.)
