1) Yesterday, there was no murder by the Mafia and no second night kill by the Maniac.
2) Yesterday, there was a note allegedly from the Hacker (but in reality, it's unknown who it's from): "I'm continuing to hunt for Vasya, and for now, I've only found that Vesper and Kosh are somehow too different."
3) Today, there was a note from the Maniac (definitely from him): "Kosh is not Mafia, 100%."
If you compare all of this, you get a fairly clear picture: yesterday, the Mafia targeted the Maniac, and he realized this because his second night kill failed. The Maniac decided that the Mafia also figured out his role and, as Vesper already noticed, he became afraid for his life. Therefore, tonight, he used a reset. If we assume that both notes are true and compare them, we can draw a clear conclusion: Kosh is a Town member (or the Maniac himself), and Vesper is Mafia. I think that it's now more beneficial for the Maniac to expose the real Mafia member than to frame a Town member. Because the Mafia knows who he is and can easily kill him, but the Town cannot. This is the only explanation I could find for such a note. This hypothesis is somewhat confirmed by Vesper's behavior, but there isn't much certainty here. And if we take into account her accusations against Ment, then ultimately, I think the role distribution is as follows: Vesper, Neyra, and Gur are Mafia, Ment is the Maniac, and the rest are Town members.
