Took my guitar to a luthier/tech to get setup and it came back with this

Took my guitar to get setup with a luthier who seems to be well respected and knows what he’s doing. And it came back with substantial damage.

The luthier said it was like that when he started working on it. He said “I just assumed you knew it was there.” And “I looked in the case to see if there were paint chips or anything and I didn’t find any so it must have already been like this.”

The guitar (a Jaguar) was brand new, I played it for a couple days before I brought it in. It was never dropped, never bumped or anything. I’m hyper vigilant with my guitars, maybe too much so… I’m very sure the guitar was not like this when I dropped it off.

Also in the 3rd picture the plate against the metal part looks all roughed up and I don’t think it was like that before. He said “I didn’t take the plate off or mess with it. But I noticed it right away… I dont think it was like that before.

What would you do In my situation?

Is the guitar going to be ok? Will this affect the way it sounds? Obviously bare wood is showing and the body is cracked, is this going to lead to problems? Like, is the guitar going to be ok for playing and recording, or is it seriously fucked?
