Has anyone else noticed a radial pattern develop around the shop heads when riveting ribs to main spar? The picture doesn't show it very well, but in the right light, it shows up radiating out from the rivet hole about 1/2 inch in all directions. I'm hoping it's not in the metal, but just caused by the anodized surface.

You got it right. It's normal.

Perfectly normal...it is the anodized surface.
