I want to have smartest AI I can, but without too many AI cheats. So two questions.

First, is AI smarter on higher difficulty levels, does it simply use some hardcoded cheats, or both?

And second, these all AI cheats for Ultimate AI right, and it's all independent of difficulty level?

  • settlement tax on player (campaign_script.txt)
  • free money + per settlement money for AI (campaign_script.txt)
  • generals' +3 command/chivalry/piety/loyalty bonus for AI (export_descr_character_traits.txt)
  • generals' +5 sight bonus for AI (export_descr_character_traits.txt)

Are there any other serious AI cheats, either hardcoded, or present in default scripts? I've heard settlement growth bonus for AI mentioned a few times here.
