All this stuff about iterating unstable loops to a stable limit (assuming that one even exists) can be a good way to think about time travel from the outside, but that can’t be how it appears to the people on the inside.
Harry, for example, already sees ‘reality’ as a quantum waveform. He is not limited to naive models of the world. “Iteration to stable loops” isn’t a concept that is particularly important when considering time travel of the kind in evidence in HP and in the presence of a complete physics that does include quantum mechanics.
“My brain will be hacked” is not actually the most simple or likely outcome except in the sense of “narrative simplicity given naive author”.
