I'd say you have your questions answered but so I can be part of the conversation, lol, I'll echo what others have said:
50% RH is fine. That is what my basement is during the summer. It does get a little dryer in winter. I have a Goldenrod in my safe also and a humidity gauge in the safe as well. My readings are 50%.
I have seen zero signs of corrosion on anything in there, including my muzzleloader which hasn't been shot in over 20 years. Yes, I do run an oiled patch through the bore occasionally.
