Ryukishi ended Umineko with this idea that he wouldn't spell out the full and total truth even in the end, giving enough clues that dedicated readers could use as a solution while keeping to the idea presented towards the end about preserving the catbox.

But, maybe he reconsidered or enough people complained, or he intended to do this from the beginning, so during the episode 8 manga adaptation, there are three chapters called Confession of the Golden Witch. This explains the culprit and their motivations, how they performed their crimes, and reveals the solutions to a few specific mysteries as well, all in plain terms. So the final answers are there.
