Hi, Jon!

1.
My question here was, is my assumption correct that there are only 2 configurations (not 4 like in generic case) for these 2 variables: either isGuest == true && isSignedIn == false or isGuest == false && isSignedIn == true ?
You said that isGuest == true && isSignedIn == true is not possible, which makes sense.
But neither is isGuest == false && isSignedIn == false, correct? If one is not signed in is their "role" automatically set to "guest"?

Please, see: https://test.immunespace.org/study/Studies/SDY269/dataset.view?datasetId=5014&Dataset.viewName=full
I don't believe you're registered, but we have self-registration available there.
Let me know via ldashevs@fhcrc.org if you have any further questions...

Thanks.
