The Mafia JOAT would use their 1x Encryptor on N1, and for D2 the Mafia PT will remain open. The shot would be consumed.
I'm leaning towards it not being able to be used pregame for D1, only N1 onwards.

I understand the concerns about informed being variable. I am fine with giving pre-determined information unreliant on the number of town flips. (this would be the first spoilered bit.) Bolded are the roles that the information refers to, to make it easier to read. When the mafia receives the information, it will not be bolded.
I would probably opt to send this info straight into the Mafia PT regardless of its iteration as soon as Night 2 began as long as the Informed Goon is still alive at the beginning of Night 2.
