From what I can find, "/md/Job_Helper.xml" seems to be in charge of making shipyards seek out jobships to build.

That's because the game only checks for ship traders every 29 minutes.
With ships of the wrong size category showing up, it's due to the workaround only checking for "shipyard" and "wharf", not the individual build modules and their capabilities.
I suppose carmaster can change it to use the "canbuildclass" property for more specific filtering.
With the engine and turret categories being disabled, having L/XL and S/M build modules on the same station causes the "engine" and "turret" categories to be overridden by the "engine group" and "turret group" categories, which S and M size ships don't have any connections for.
