The new VS picture :
these lines could be from internal structures, but evidently highlighted by external factors (pressure, collision?)
But, there are more new defects on the surface, like abrasion/collision marks. (Etud lAvia was faster than I). The external skin of the VS looks very flexible, probably a glass fiber or aramid fiber composite (not carbon fiber), and specially the leading edge of the VS must be very sturdy. I can imagine an aluminum skin got there and caused overload and snapping of the VS.
Look here for an A320 cut away
A320 Cutaway View
(there maybe differences to the A321 or other internal structures not showing in this cut away)
For me, the yellowish structure here:
(see also :

is not the jack screw support base (supposedly pushed upwards), but one of the internal structures of VS, which now is downwards inclined. That would have pushed teh screw jack plate forwards, pulling the jack screw also forwards.
Also look here:
did you see the metall piece? What is it supposed to be?
