Yeah, I think one of the most likely failure points - speaking as a complete nonscientist - is going to be the seams, where the titanium caps met the carbon fibre tube. I think they look fairly undamaged because they just popped off when the carbon fibre failed, rather than getting distorted and shredded up. The stuff we're seeing all seems, besides the endcaps, to be stuff that was basically stuck on the outside... the tail, the outer shell. Not things that were inside the zone that was a different pressure. So maybe they were all popped off and thrown clear.
The carbon fibre hull, the electronics, the people... they were at ground zero. Nowhere to go.
Very much my opinion only
You may be right. Here's a video of them attaching the titanium ring to the carbon fiber hull. (The end cap would then be bolted to the ring.)
It's striking how this all appears to be done by just eyeballing it. It wasn't a dust-free, temperature & humidity controlled environment and the epoxy looks like it was spread unevenly.
I should note that this video was taken in 2018 and they apparently repaired or rebuilt the hull in 2020, but it's not yet clear exactly what that entailed.
