Review Comment:
Thanks @sungwy !
> function of the table's commit state and the client identity.
ReadRestrictions adds a new axis of cardinality: they're evaluated per end-user
subject that the trusted client propagates
I am not sure if i understand the difference between identity and subject
here, what ever inputs were used for vended creds will be the same used for
computing the ReadRestrictions, we don't define whats the inputs taken to the
compute the vended creds either ways.
