To clarify, by "one for the road," I don't mean I'm completely dipping out on the project! It's just that I'm going to get a lot less useful, since you're developing a different version of the game from the one I'm commenting on. I feel like it's just courtesy to therefore zip my gob.
(I actually haven't stopped getting ideas and noticing things about Roguefort, though. I'm planning to type up a proper list and upload it to the Discord as a PDF; that seems like a QoL upgrade for you, compared to a bajillion comments.)
In terms of credit and an NPC . . . wow, that's amazing. I'm genuinely touched.
My instinct, if I'm potentially being credited for stuff online, is to ask for "Merlin Grace" as the name given. I do have some misgivings about that, though, since Merlin Grace is sort of my "stage name" for various art projects, and I don't want to use you as free advertising. I don't have any misgivings about saying that I want "my" NPC to be named Merlin, though, since my affineur is named Merlin too!
