Does the screw advance and return when you screw/unscrew it?

It does. I don't think it's stripped since I can't pull it out without
turning it, and it does cinch tight against the derailleur body if I
turn it all the way in. It just wobbles a tiny bit laterally because I
think we're looking at this photo-realistic cross-section:

         threads on derailleur
           v
    |\    ///
    ||\\\\\\>  thin air inside the body
    |/    ///

Look on the back side and see what, if anything, that screw hits.

It vanishes into the body of the derailleur and I can't actually see
what it hits--I think on this model it presses against an internal
spring.

After a chat, the online seller decided to send a new derailleur, so
we'll see how that goes. Just glad they didn't want me to ship the bike
back. :)
