Wiping Over Socks
There has never been any disagreement in its ijma or tawatur. The only disagreement is the interpretation of few conditions in this regard which according to some are described in Hadith Corpus. So they do tehdeed (limit) regarding scope of its applicability because Ahad is an equally acceptable source of religion to some, so you will find many overriding fiqh in this regard. But the Wiping over socks as an allowed act that has been transmitted through ijma and tawatur.
Bleeding is purely a fiqhi matter to the best of my understanding.
