Airbus FPV uses barometric vertical speed and inertial groundspeed and attitude (explained in BEA report).

I agree entirely with your analysis. The airplane stalled after 2:10:51.

First three sentences agreed. However at FL375, 215 kCAS, AoA=4° the airplane is not stalled: the normal acceleration is less than 1 (approx. 0.8) hence v/s is decreasing.
