Similar to Amp prisms being the part that defines whether a new amp will net you mastery xp or not, depending on whether you've ranked up an amp with that prism before - then I wonder:

what K-drive part defines whether you'll get mastery xp from a new one? Is it the board part? I think its the board part - but does anyone have confirmation?
