Apologies. This might not be the perfect community for the post.
So I'm late to the party here, but this is a very early version of a diagram I'm putting together that corrects a couple of issues with the diagram OP posted.
As I said: very early and also very incomplete, but what's there is accurate.
I’m into it! I can’t wait to see where this goes.
