Hi Machinbird,

I suspect the rejection mechanism would be primarily ram air impingement into the static ports.
I'm really curious to read your full explanation with such a "deep stalled" projected AoA achieved in normal law inside her full envelope protection; those ram air impingement into static ports able to trigger ADRs rejection without impacting her engine's air flow; explaining also this attitude at impact while she is still in a "deep stalled" and clean configuration; and the whole sequence lasting five minutes of descent from a very early upset before 0210.

Quite curious so.
