hmm...nasty CA (heavy purple fringe)

Purple fringing is not CA. The correct term: Longitudinal Chromatic Aberration (LoCA). It comes in two colours at the same time. Magenta in front of the focus plane, green behind the focus plane.

Purple fringing caused by the lens fits the definition of chromatic aberration.

Not really. It is not "caused by the lens", but rather how the lens and sensor interact with bright reflected light. Which is why PF is not seen with the same lens and the same light when shooting film.
