What Determines AI Command Stars

So far I've noticed that generals that belong to AI factions are somehow awarded command stars that don't match up with their visible traits. I know that they get hidden traits in order to balance things with the (naturally superior) human player, but just out of curiousity, can anyone tell me what these traits are and how they get assigned? Assuming they are awarded through traits, that is.

They are hidden traits awarded to generals that are not yours. It is that simple, just not yours...

Q: what determines AI command stars?

A: EB developers ~D

OK, I guess it's time to start digging through the ole' EDCT.txt.
