Looking for any insight or theories how this could come to be…

My LBS sent me this picture at my request after describing what they found over the phone. I had dropped my bike off with them for a noise that seemed to be getting worse coming from the BB general area.
The bike is a Quintana Roo SRFive with only 800 miles on it. The bottom bracket has never had any work done to it prior to this. The body threads do seem to be fine thankfully.

I should mention I sent the pictures to the manufacturer and the LBS contact info. That was yesterday afternoon. Parts are on order so I’m hoping to have her back on the road next week then deal with the warranty claim.

I didn’t want to skew any initial answers so I didn’t mention the LBS said the same thing as the consensus here seems to be: bad install.

Remaining questions: is there literally anything else that could possibly cause this, and could it really have been like that for 800 miles before starting to become noticeable?

I’d just like to go into this warranty process and any included discussions as knowledgeable as possible. I have a mechanical background but not bike-specific…

Ugh. Well the LBS called me back yesterday afternoon. They got the new part and did attempt to install it, but the frame threads were causing grinding so they stopped. They told me they don't have the specific $600 tool to clean up the T47 bottom bracket threads on the frame, nor does anyone else they know of in this area.

I'm waiting to hear from the manufacturer now on a warranty claim... I have a feeling I'm going to be shipping it off to them soon which means I won't have my baby for a while. What are the odds they repair the threads and send it back or they give me a new frame?

It's frustrating but that's why we have n+1 bikes, right? Could be worse; I'm glad its winter time not summer/spring.

While you're waiting to hear from the mfg. it wouldn't hurt to call around to other bicycle shops asking if they have a BB threader/facer. It's a tool that a well-equipped shop should have.
The mfg replied they want the frame for evaluation before I even had the chance to call around. My shop said the T47 thread tool is a somewhat new design and not well stocked yet...
I'll be shipping the frame to them in the next couple days. I'm mostly nervous they'll find something else to blame besides cross threading the BB. I can't imagine what that might be but still.

Ok so backtracking a little…

Teardown and reassembly is considered a ‘level 3’ service, costing upward of $300, plus boxing at $80, plus shipping estimated between $150-200. So nearly $600 just to send it off to be evaluated for a warranty claim…
Anywho that was enough motivation to call around and I found another shop who managed to thread a new BB in… but it wasn’t wide enough so the exact replacement part is now on order.

I’m excited I should have her back on the road by the middle of next week. I felt like I was getting out of there too cheap so I’ll buy some stuff in the shop and I commissioned a couple extra services while they have the bike. I’m also a little annoyed at the warranty process. Fingers crossed I’ll never have to think about making another claim.

Are you working with the shop where you purchased the bike? Are they are authorized service center for Quntana Roo?

Park has the tapping tool (BTS-1) and the T47 tap in stock. Seems to me a reputable shop should have these for this very reason, especially if they sell (and support) bikes with T47 shells.
If I’m understanding correctly what I’ve been told by a couple shops, t47 is relatively new and becoming more common especially on Treks, but still not incredibly common. First shop didn’t have the tool, another shop decided to order it after I called because it wasn’t the first to request it, and the 3rd shop had it on hand.
I did a lot of my shopping online to compare specs and prices between brands and didn’t want to wait months and months when I bought it last year, online. It was delivered a couple weeks later built to the specs I chose. It’s amazing how quickly the supply chain has caught up in just that short time. Quintana Roo, aka American Bicycle Group, hasn’t identified any shops they consider an authorized service center apart from their own shop in TN.
My anxiety won’t subside until everything is reassembled. As it stands now the Trek shop where she’s spending the weekend has the tools but demonstrated a new bottom bracket threading in without doing any frame warranty voiding work. I really like the bike so I hope the rest of my time on it is less drama filled!
