Polished sprockets

So After cleaning my chain and riding a little bit, I noticed that the front and rear sprockets on the outboard edges are getting A mirror polish on them. To me this shows me that the chain is rubbing on the outboard side of both sprockets but I'm not sure why it would be doing that. Any ideas? As far as I can tell the rear wheel and chain line are straight.

Mine did that a little on both sides just from the chain
bouncing around while the whole assembly is whizzing
in circles.

I understand what you are saying though. The wear was
more pronounced on the outboard side of the front and
pretty evenly on the rear.

My method of keeping it straight was counting visible threads
on each adjuster bolt. I didn't feel any need to be more precise
than that.

Do you have 500 miles on the bike? Then there's likely an alignment
or whatever spacing issue.

Do you have a few thousand miles on the driveset? Keep it oiled
and have more fun !!

Since I bought the bike a few months ago I've put a few hundred miles on it, many of them off-road or on gravel. When the bike was purchased the chain and sprockets were filthy so I cleaned them and they looked normal. Within a few hundred miles though they have polished up quite a bit.
I have had the rear wheel on and off several times chasing an air leak in the 16 year old tube, and recently finalizing a tubeless conversion which seems to be successful.
Everytime I try to reinstall the rear wheel it seems like there's not enough clearance to get the wheel back on. Like I have to flex the swing arms apart to fit the hub in between them.

I'll suggest maybe you go around right hand corners faster and therefore lean farther to the right, so gravity is the reason.
Pick up the pace on LH curves.

Just kidding. If the chain and sprockets and wheels look 'in-line' to your eyes and your slack adjustment is loose enough to lift the bottom chain run up to the rear tip of the rubber slider, I'd ride it.
