I think we mean the same thing but misunderstand each other.
So we agree addons.config is what OH uses and that is changed whenever a change in any of its sources triggers that.
My point - remember my post is to adress users - however is you need not (users even shall not) manually change it but only ever modify the two input sources addons.cfg and PaperUI.
Neither of these is the single source of truth but for each parameter, only one of them ever takes precedence, meaning it is “the” (only) source of truth for that parameter.
