Hi Thomas - I was not tracking my own question here! I apologize. I'm still
hacking around this - that is, returning my new instance from my
InstanceRequest "persist()", then turning around and doing a
find(response.stableId()) on it to get a usable EntityProxy. I'll paste the
wire data below - it was the smallest back-and-forth in my app I could
find. Let me know if you need me to dig something else up for this or help
decipher anything.

(I have a hunch that on the server side, an incomplete @Entity is being
passed to the GWT serializing code before the @Transaction demarcation
completes and the entity in memory is totally updated. Hunch.. I am not
certain.)
