If they get the flight data recorder it will have all kinds of settings
and parameters recorded from which the engineers should be able to
understand exactly what the airplane and pilots were doing. They can
then run that through the simulators and see exactly what might have
caused the problem.

Big nagging question in my mind - how do they replicate the failure when
testing?

The difficulty is that a single point failure (flaky attitude sensor in
this case) causes an un-needed actuation and severe nose down pitch without
warning the pilots, who are well aware of what the plane is doing.
Having the "stick" snatched out of your hands by the computer without
warning is a bad thing.
The old stall warning on the 727 shook the stick a couple times before it
forced it forward, along with a horn and the annoucement "stall". This
system just rams the stick down.
Nothing wrong with the idea, but the implementation is horrible, and not
putting it in the training OR the flight manual is just flat criminal.
