No evidence of water in the panel - anything I may have missed? Would high humidity cause interior condensation?

I don't think it is worth trying to find what went wrong. Maybe it was mistreated before you got it. If this is the only rust, I would just replace it.

Could been that way before it was installed in this panel?
Be kind of rare to see just one like that if it happened while in that panel.

Maybe if it was at the top and water dripped on it from the supply connector but that doesn't look like it happened there. Take the cover off and look at it.

Likely some “new old stock” that someone got hold of that had been left in the rain somewhere.
