Help - Rear Triangle Width mystery

I bought a used 2014 Trek Crockett Disc 5 and had a small mechanical problem on the first ride. Upon removing the wheel and trying to put it back in I noticed that the axle didn't quite fit right but was able to get it tightened up. According to my research this is a standard 5x135 mm frame. I took it to a Trek shop and digitally measured the width from inside-inside the dropouts. It measured in at 141 mm. When we put the dropout alignment tool it was straight as an arrow (not bent). I contacted the original owner and he, of course, said he didn't know anything about it. He said he always used 135 mm hubs and never noticed the problem. It was now my problem. Super good dude. Especially when I noticed the freehub body was shot. Both myself and two people at a Trek dealer could find no cracks, bad welds or issues with the frame. It looks super clean. It left us all scratching our heads. I would need an x-ray machine to dig deeper. If I tighten up the wheel it is solidly engaged.

My questions:

1. Has anyone seen an aluminum frame spread like this?
2. Has anyone witnessed variance when a frame comes from a manufacturer?
3. From a safety standpoint, is this something to worry about?
4. Has anyone used the dropout alignment tool on a Trek Crockett from that year (if I could squeeze 2-3MM on each side)?

Thanks

Thru Axle is different from older QR axle frames..

One concept : you may adapt the threaded hub axle from a Shimano Tandem hub,
which is for a 145 OLD so take a little off the ends..
add spacers to left side and you can de dish the wheel over to that new center..
