I use luadec myself, then I compare the decompiled code to the Evans version to figure out what changed. That's how, for example, I found how they moved the "Tourist" trait from the "Other" to the "Specialization" group.
Btw, it's not to sound dismissive of the dev's work but they seem to have left some unfinished work. I think that Tourist should be it's own "specialization" with a specific uniform to distinguish visitors from permanent residents. Unfortunately I didn't find a way to create my own custom character entities except by using recolored existing models as for the "Bureaucrat" specialist in the "Martian Policy" mod.
