Maybe the right time then for you to correct your own assumptions and to reevaluate your facts presentation as no such ECAM MSG was presented to the crew.
The crew was not aware of the ADR 3 rejection.
During the 40 minutes period before the crash an unambiguous AOA DISCREPANCY ECAM MSG could have been presented to the crew.

A CHECK GW MCDU MSG is certainly NOT a CLEAR indication of AOA DISCREPANCY especially when it was not possible to determine if this message was really presented to the crew.
However, an unambiguous AOA DISCREPANCY ECAM MSG would be a clear indication.
The ISATM schedule called for the (Test) crew to record the 3 AoA values prior starting the test. This would have shown the AoA problem.
The crew has rushed and was clearly poorly prepared, but how would you want them to check those 3 AOA values when only 2 are available and so only indirectly through the third MCDU ... ?
