This planet has been colonized and under sector control for ~100 years. I've given infusions of minerals and energy to the sector multiple times. It is not running a deficit in either resource.
The Ai works for me quite fine.I'm still not clear on the value of this tool.
The problem isn't that sectors are a black box, it's that the AI inside that box doesn't work. Knowing what the AI is planning to do doesn't help me if I can't do anything about that.
