[Q]

As far as I understood the AI unit construction file was meant to be a backup construction instruction for colonies/spaceyards that would have been idle otherwise.
So yes, the AI uses the vehicle construction and facility construction file first and only considers the unit construction file afterwards. Therefore in the beginning of the game the unit construction file will probably not be used. But IMO this is right or would you prefer the AI stop building colonizers and therefore expansion to build weapon platforms?
There is however one problem with new colonies: I usually build one or two weapon platforms first before I start building anything else in order to protect the colony. I see no way how you could instruct this to the AI. In my experience the AI will always build the facilities first.
