From when I worked as an engineer on the assembly line for smaller jets, know that there would be a record trail of exactly who completed the work, who signed off on it and what the work order steps were for anything related to these assemblies and components. This would include the work done at Boeing and their suppliers. Will be interesting to ultimately hear the root cause here.

Let me ask this: assuming they did not tighten the bolts correctly and qa didn't check it, what are the odds they keep an accurate paper trail?

Close to zero, but that doesn’t help them. If the paperwork was falsified to say that everything was tightened and verified, and Boeing stands behind that, now Boeing has to investigate and come up with a plan to prevent these bolts from “mysteriously loosening” (because everything was fine when it left the factory)… which will be an even bigger pain in the ass than just fixing the QA process.

Maybe bring in some QA professionals from... Airbus.

I mean, if they are not doing it in good faith no matter what happens is going to be half assed.
