I was going to use a small balloon over one of the fill ports.  If I did
the PV=NRT thing right, a 50C gas temperature would raise the volume about
10%.  The glass plates are mounted with flexible silicon so they can move
with temperature changes as needed.

The balloon would provide a little pressure so any leaks would leak outward
and keep the gas pure.  If the balloon goes down, I know it is time to add
more gas or go looking for a leak.

Darn, I just read that in my studies.  It wasn't important to my gap so I
didn't pay attention to it....
