Your post #816:
The crew had not detected the UAS situation, but with ADC dropout/changeover the (unwarranted?) stall warning was taken as real.
The stall warning resulted from the pull on the sidestick, added to light turbulence. It was real. Stall warning does not occur in normal law, only in alternate or direct law.

The CVR / report suggest that the crew observed the loss of airspeed information but did not understand the implications, and possibly did not consider any association with UAS.
You seem to be making a distinction between "loss of airspeed information" and UAS. Do you mean they did not associate the UAS procedure with the UAS situation?
