Or maybe the build model could be simulated another way outside of faf?
in theory yes - in practice no
the issue is that you'd need to simulate the whole engine. the engie doesnt go at its max speed and then stops. it accelerates and brakes. and 1000 other minor things like that will add up which then will cause a massive diff between your simulation and a real game
but you can pick up my approach - the ai can read all the orders of each engie, it can now every metric (where which treegroup is and how much mass it contains etc) and it can read all eco stats - so in theory you could use the ai just for the work that originally i intended to do manually. if thats better...idk. especially for astro crater it is very simple to find the optimal bo
