“whoever signed off the paperwork saying these procedures were followed”
I think your referring to quality control, and yes more than likely the documentation is all electronic which means it should be available at virtually the push of a button.
However, last I heard was Boeing was unresponsive to turning over that data to the NTSB.

It depends what data is being requested.
The aircraft left the Boeing plant in airworthy condition with a door. Spirit performed the door plug modification. It either was or wasn’t installed properly at that point.
The plane was delivered to Alaska Airlines. Alaska Airlines performed maintenance on the aircraft. It was either done properly or it wasn’t.
I have a hard time placing blame on really deep pockets Boeing since the door plug is not their modification. That’s most likely why they are all lawyered up.
