Yeah, I see what might be the subtlest seam (which could be called a “void” but isn’t really the same as what most people mean when they say that word) in the carbon sheet layup but no crack. Unless it grows I have considerable doubts that it’s a crack…the vast majority of cracks that aren’t caused by crashes will start at a tube junction and cause the paint to separate or fall off. The paint was intact over this seam until it was sanded off. This is far enough from the nearest junction that I’m skeptical.
It’s not impossible, but without being able to see it in person, I have my doubts.
