Las, “Perhaps you meant ???? ???? ????? ….. even though the ???? occasionally is wrong also,”
In terms of the Talmud there is no “wrong” as per the Gemorah in Eruvin 13b and Gittin :
???? ???? ????? ??? ???? ???? ???. ???? ?????? ???? ???????, ????? ?????? ???? ???????. ???? ?? ??? ?????: ??? ???? ???? ?????? ???? ??, ????? ???? ???. ??? ???? ???? ???? ???? ?????? ???? – ???? ?? ??? ??? ??? ????? ???? ?????? ???? ?????? ??????? ???, ?????? ?????? ????? ???
????. ??? ???, ??? ???????? ???? ??? ???? ???????”
See the Ritva there, explaining the obvious question – how is it possible that BOTH can be true, it is either Tuma or Tahor/Muttar/Asser?
He explains that Hashem had originally presented Moshe Rabenu each Halacha with two sides of the argument (actually 49 reasons to each side) and, that the actual psak will be up to each generation’s Chachmei hador. Thus in essence, they are both Toras emes given by Hashem
Also, see Rashi in Kesuvos 57a:
??”? ?”? ?? ??”?-
“??? ?? ????? ??? ?????? ???? ?? ?????? ????? ?? ?? ??? ??? ?????? ???? ??? ??? ??? ?? ?? ??? ???? ????? ???? ?? ???? ???? ??????? ??? ???? ???? ??????? ?? ???? ????? ?????? ??? ??? ???? ??? ??????? ?????? ????? ????? ??? ???? ???? ????? ???? ?? ?????? ????? ??? ???? ??????? ????? ??? ???? ????? ????? ??? ????? ?????? ?????? ????.”

I recall the Marshal in Yam Shel Shlomo writing about it in length, in his introduction to Masechet Chulin or Baba Kama..
