I am Queter, a Radch-Aligned Shy Bugged Compulsive Visitor. I have to visit someone every night. If I don't get targeted by anyone and my Visit will be successful, I will become Self-Aligned with powers and win condition yet unknown. Bugged part of my role is that if investigated I will return Human or AI result with 50% probability for each. N1 I targeted Haddock and nothing happened.
Two other points about LL's claim that have me thinking that it could easily be fake:
The "Shy" modifier presumably is related to the alignment-changing part of the claim. However, LL's alignment would change if she's unable to visit or if no-one targets her; that sounds like the opposite of shy to me, so it could be a modification of a real role that LL knows about somehow.
"Bugged" makes sense for a role that would give an AI a chance as identifying as human, but less so for a role that would give a human a chance of identifying as AI. Of course faust could have given the Bugged modifier to various people and just called it the same thing in all cases, but it feels a bit out of place here and could easily be something that scum!LL took from her true role or one of her teammates' roles.
