Exactly! Appears the jet was flying the crew.
Haven’t looked at the graph yet but, did climb power ever get called for and set?
Nope.

From the Prelim:
During takeoff roll, the engines stabilized at about 94% N1, which matched the N1 Reference recorded on the DFDR. From this point for most of the flight, the N1 Reference remained about 94% and the throttles did not move.
But takeoff power, 340kts +, overspeed clacker clacking and a ~1600 fpm climb rate is all normal procedure right?
Another thing on the graph:

From the Prelim:
At 05:43:20, approximately five seconds after the last manual electric trim input, an AND automatic trim command occurred and the stabilizer moved in the AND direction from 2.3 to 1.0 unit in approximately 5 seconds.
That would be the re-engagement of the Stab Trim Cutout switches. Funny the Prelim doesn't mention that.
Looking at the graph, 05:43:30 is where the terminal dive begins. It would suggest that the re-engagement of the Stab Trim Cutouts, an action step in total disagreement with the Runaway Stab NNC, was pretty much the last link in the accident chain.
