Export testing works. I did notice the UUIDs saved in the ObsUnitID column are the deltabreed UUIDs and not the brapi server UUIDs. That's what's being shown in the UI experiment table as well. Is there a plan for those to eventually be the brapi UUID or to maintain separate ids?

I'd say this is work for the obs unit program cache removal tickets, not for the trials.

I do think we should change those IDs to be from the brapi side, since they are unique there.
