I fail to see the connection of automaton with the problem at hand..

comment How to prove and interpret $\operatorname{rank}(AB) \leq \operatorname{min}(\operatorname{rank}(A), \operatorname{rank}(B))$?
I am not familiar with the 'categorification'. How can one go from this to the rank inequality ? What functor is to be applied ?

comment function application order
i think you are right about the conclusion. it is the convention of most textbook, so i better suck it up. i notice that lawvere uses the natural order though !(tac.mta.ca/tac/reprints/articles/16/tr16.pdf)

comment How to prove hom functor preserves pullbacks
@user43687 yes this is more powerful, although I quite like to have the direct proof as well.

comment Pullbacks of monic morphisms.
of course, by the universal mapping property on the pullback : that there is a unique $h$ making the diagram commute aka realizing $ g m'\circ h = m f\circ h$

comment Pullbacks of monic morphisms.
going to $f \circ h = f \circ k$ is easy, but I must be missing something as I dont see how that entails $h = k$. could you argue why ?
