If uncommanded by PF (or a/c), the climb may have been addressed with PF's 'Nose Down inputs'. I think BEA have not specifically timed those.

Likewise, he would not advance Throttles (he did not).

The second STALL WARN, could actually be predicting the STALL that resulted from loss of energy in this climb (which thus far is not described as to origination). The AoA (not necessarily PITCH) would increase as the Plane slowed, independent of elevators that had lost their effectiveness anyway. As the Plane dropped Nose (Either as a result of controls OR STALL), the AoA would reduce, hence TOGA and 'backstick relief' as the a/c "STALLED". At this point, had PF done nothing, he may have recovered? (No TOGA, no 'back pressure' held). Saying the pilots did not know they were Stalled is presumptuous.

At this point it is not determined if NU inputs are slight (inadvertent) pulls by PF, and not a back (climb) command. It could indeed be a trained APPROACH TO STALL recovery, at a very inopportune time.
