There is nothing in your last posts to disagree with.
The STALL occurred after the aircraft died. No argument. The mayonnaise stirring is far more important than the Stall, or even the climb, imo.
One way to recover is to fly to a heading. Oblivious of heading, apparently, and unwilling or unable to correct ROLL, plus a fixation with a dumb distraction are the reasons this crew failed?
The "Committee" approach to recovering a dangerous flight Path won't work, ever. And if in the simulator, one can "do-over".
One of the most egregious blunders was the calling back of the Captain.
A bad situation became impossible. The highly trained division of Labor took a holiday, and troubleshooting is for mechanics at the base.
What was broken about the THS? You mean mechanically, operationally, or theoretically, oh, or Philosophically? All of the above.
Nothing about what happened to 447 should be seen as being sacred. Including kit, ego, and compassion.
