I want to thank the general "group" here for all their help, both answering questions and providing a history I could look at of past questions. Gas pipe is run to second floor, passed the "pressure test" (20lbs 20 minutes) and also the bubble leak for the parts I couldn't pressure test. All is good in the world, and I can take a warm shower!
As an apparent plumber I'm sure you know that you can't pressure test gas connections to the appliance and commonly people close the shutoff valve for the air test. Therefore a soapy water test of those untested fittings is incredibly prudent.
