I'm not afraid to leak this information to the Mafia, because they have a collective mind and will figure it out on their own. It's important to hide what can be hidden, not these kinds of things.
If I remember correctly, we have 3 roles in the game whose execution essentially won't give anything – these are Mother, Father, and Doppelganger.
None of them are executed on the first try, and they will only reveal that the votes were cast, the execution failed, and the pool of roles will be narrowed, but they won't give a precise answer.
Mother and Father have 3D/aggressive statuses.
Doppelganger came up with his own status.
The problem with verification, in my opinion, is that the only town role who could accurately say what the Master's status is is Waifu, who could compare two Masters, but Waifu won't tell us anything anymore.
Love could also do this (but then something would be written about it in the newspaper), and the knight-addict, who requests the status after defending.
Or, the Mafia Reaper, who visits one Master for 2 days (which is also a question of why?).
I wouldn't consider the Doppelganger. You can't redirect Mother's ultimate, and even on the first day, the information isn't 99% certain.
