None of those convey that these are things which send their state back
as RDF....

Sorry, I'm not trying to suggest it is or should be for us -- I was just
giving a long-winded explanation of how I came to be okay with the term
Resource.

More formally, I suggest that GraphStateResource just be defined as
anything for which it's entire state can be conveyed in an RDF Graph,
with reference to REST.

REST is a simplification of the Web, to be sure.  It's probably about
right for these purposes.

None of those terms are any help for us here, trying to name a
generalization of a g-box.   We still need a term that limits it to RDF.
