There should be no behavior changes in this commit, it just adds a more expressive data type and adjusts code that had been passing around a [UUID] or sometimes a Maybe Remote to instead use [VerifiedCopy]. Although, since some functions were taking two different [UUID] lists, there's some potential for me to have gotten it horribly wrong.
