Re: Pedantic Star Trek discussion #134: Riker's Field Commission
Isn't it obvious that the promotion was never official since the paper work was either never sent or blocked by Borg subspace interference? It was up to Riker to contact the Starfleet HR department, something that he may not have ever done or mentioned in an official log.
Or perhaps like Decker, Riker was a recipient of a "temporary rank reduction" albeit willingly in this case.
