If it were a problem with the shutter at the focal plane why are black smudge edges fuzzy and not distinct lines?

Because the shutter is moving, not stationary.

Many years ago, I had a film camera with a sticky shutter that showed similar fuzzy dark bands along one edge of the frame. The shutter curtains were not moving in synchronisation.
