The flight tests did not go beyond approach to stall
Makes me wonder why I did 3 QTG's recently that encompass 'the stall', as validated by IAS, buffet onset, stall AOA, and VSI break? QTG's come from flight test data.
There is a big difference between 'the stall' and a 'developed' (better word, aggravated) longer term condition.
One always needs to check the certification basis for a given aircraft...
as JT says.
