I am heading off to bed, but I will at least give a quick reply to this part (have not read much more of this post): I don't agree with this.I would say the check mechanics do provide some information, if we accept certain GM guidelines is in play. For one thing it has been argued that what the inputs to the check is (skill, particular difficult or simplifying circumstances, magical bonuses etc) should inform the narration. I would argue that what is considered valid inputs to a mechanic is part of the mechanic. The "output" of success/failure is an important modulator, but it isn't the entirety of the mechanic.
I don't see those "inputs" as being part of the mechanic. When we do that, again, it looks like any mechanic which ever involves any amount of in-world information whatsoever....which should be every mechanic, even ones people super duper ultra dislike for not being properly/sufficiently connected to the world....then it's necessarily diegetic and thus anything is diegetic if the designer puts even the tiniest thought to it. That is, now every roll based on any number that comes from a character's sheet is definitionally diegetic, and I don't buy that for a second.
If you like, I see this as now the designer (which one might call "Director's Notes" if we continue the film analogy) giving the proverbial "voiceover" that Jane has heard the music all her life. That is, the designer doesn't get a "get out of design free card" just by having any reference, however trivial, to some input coming from the fictional world. That surely can't be enough, we need not just more than that, but a lot more than that.
