Paper author here: one cool thing about our technique is that our bot doesn't keep "notes" :)
The only thing it maintains for the entire game is this length-60 belief vector - a summary of who it thinks is evil and good. How people act influences this belief vector, but it can't look back at the game history. This leads to awkward play sometimes - it will propose missions that have failed in the past, etc. I think it's cool that we (humans) can summarize the state of the game with such little information, and that the bot does something similar :)
