I just realized, Rose's tome that Callie owns is probably a paradox. Her future self probably told Rose about it when she got in Earth C's non-desolate future. Which means that it could be possible the tome is inaccurate? Like the gender-lock, passive and active and all of that jazz.

I don’t think Rose wrote any more into the tome AFTER they left the Meteor, otherwise it would have no reason to actually have been left in the Meteor. Besides, I doubt Rose wrote specifically about Class and Aspect Passive/Active or Gender stuff, the Gender Lock is just Callie making theories about the Classpect based on the stuff she has seen- Gendered words, Class-Gender Distribution, and coming to her conclusions about that stuff.
