A4 :
It is interesting that the DFDR and CVR are reported as "damaged".
Not quite : the "boxes" themselves seem to be physically OK, it is the contents ( at least of the CVR ) which is reported to be not "exploitable" as the BEA says.
This might indeed be the case, the problem is that in France,and surely by coincidence , this kind of things seem to arrive a bit too often, especially when involving AI types. Therefore the suspiscion.
To make matter worse for the BEA , the State prosecutor first declared that the CVR was recovered and readable, and 2 days later said the opposite.
