No it does not and that is your erroneous understanding. The proof is self-evident because none of the myriads of other languages in the Indian Subcontinent have been supplanted by Sanskrit. In fact there is a theory that Sanskrit was never a spoken language for common folk but merely a written one due to its precision. Also there exists multiple scripts to express Sanskrit in other Indian languages eg. "Grantha" script for Sanskrit->Tamil. All South Indian Classical Languages use their own scripts to write Sanskrit.

The linguistic complexity amongst the various states in India is very unique and hence simplistic notions of language dominance do not apply to India as a whole but varies from state to state.

The linguistic complexity does not exist in the philosophy. You are taking the modern state of India and imposing it on a language which neither originated in the country of “India” nor even had a direct relation to its contemporary history. The Brahmanical laws were absolute—the elite learned Sanskrit, developed the philosophy and literary culture, and justified their own rule through it. That entirely predates the colonial rule which formed the very “diversity” you see today. There was no recognition of any authority outside that produced through the text.

You have missed a lot of what i said/implied. First i used the phrase "Indian Subcontinent" (https://en.wikipedia.org/wiki/Indian_subcontinent) which geographically includes much more than the current nation state of India. Second, the linguistic diversity in the Indian Subcontinent is thousands of years old, well predating the arrival of Muslims/British into India. In fact, the modern Indian state lines were drawn based on linguistic identity which has always existed. So i am not arguing from the modern Indian state pov but quite the opposite.

Your statement that Sanskrit did not originate in the Indian Subcontinent is controversial and is not settled. But regardless, there were groups who had Sanskrit as their lingua-franca and who specialized in orally transmitting and then writing down their own (and borrowed from other cultures) philosophies and worldviews. The other linguistic groups in India did not do it to the same degree and hence you have the current situation where it appears that all knowledge only came through Sanskrit one-way. This is the fallacy that i am pointing out. Note that this is quite apart from what the content of the Sanskrit texts themselves may/may not convey; that is a different matter and has to be looked at through a different lens.
