The term "re-proved" is not commonly used in English vocabulary, which makes it challenging to find direct antonyms. However, we can suggest some possible alternatives based on the context of the word. In the case of "re-proved" meaning to "prove again," the antonyms could be "disprove," "invalidate," "negate," "refute," or "show false." On the other hand, if "re-proved" means to "validate" or "confirm," then antonyms could include "deny," "disapprove," "discredit," or "reject." In any case, the choice of antonym will depend on the intended meaning of the word and the context of its usage.
