Well, these normalized keys are sometimes sufficient to give correct
answers, or are sufficient to determine that that isn't possible with
just their representation. That is pretty exact.

How about "delegate key"? That's a similar term to proxy key, but is
more strongly suggestive of the idea that these keys are in some sense
inferior to original keys.
