You’re continuing to conflate “music theory” with “western notation.”
Music theory itself is far more expansive than that, and the fact that you’re pretending that only western notation counts as music theory is extremely problematic, and also the source of the disconnect.
There are multiple histories of various musical systems which are encompassed by music theory.
If you want to exclude every non-western musical system from “the history of musical theory” and define “music theory” as exclusively pertaining to western-style notation, then that’s a really shitty and eurocentric outlook, and that’s on you.
