Thanks,hardcore an accurate summary except for..
Finally, the ELACs (having failed to back up the Alpha floor based on…. you guessed it AoA inputs pg51) but now calculating Vs from the FMGC gross weight issue the STALL STALL warning. 15.45.05
As I understand it the STALL STALL warning is produced by the ADIRS (ADR portion) - presumably the standby AOA probe angle via ADR 3 - nothing to do with FMGC GW - the word "stall" does not feature anywhere in FCOM 4 (FMGC). Do you know something we don't?
And as you state elsewhere alpha-floor is done by the FACs, not ELACs. By "back up the Alpha floor" I assume you mean αprot and αmax protections?

Can we point the finger at the pilots as the sole cause? Maybe!
Not the sole cause - if the AOA probes had worked as advertised the crew would have done the alpha-floor test and accelerated back to normal speed.
