I had the same thing - also right front. My good luck was that it must have picked it up just as I entered the dealership. The service guy noticed the noise right away. Same diagnosis in my case. I guess the right side picks up more crap from the side of the road.
Just the opposite dude, you’re lucky it wasn’t something much worse! You fixed it in a couple minutes and you own a C8... luck has certainly shined down on you!
You definitely have a deep gouge there. Usually the wear indicator is in the edge of the brake pad and the mark is in the center. I wonder if something got lodged in there like a rock.

The gouge on the rotor looks worse than it is, I can't even feel it with my fingernail; it's incredibly superficial. I'm going to ascribe to the school of thought described by @19/C7Z and just move on, the rotor is fine for my street use purposes. Just incredibly unlucky I guess!
Sounded like a rock to me. Have to be very hard to gouge the rotor. Glad you found it. I'd make the dealer get a new rotor and pads. Heck they will get paid from GM to do it. With 500 miles GM will probably be happy to do it and pay them for the install.
But now you can drive it until the new rotor arrives! Would have bothered me as we'll. Like in "Dirty Harry," "I's Gots to Know!"
Now the question is...Is there something with the design where this is prone to happen repeatedly or is it just a fluke and most likely won't happen again?

cars with brake cooling ducts are notorious for this. Usually its in and out but every now and then... lol

The less time the car spends at the dealership the better. After a thousand miles, the rotor and pad will show no evidence of the rock.
Often the quickest and easiest way to fix this is to back up. If that’s not sufficient a few back and forth will kick out the rock almost all fo the time.
