A viewer account has exactly two causes, fixed in completely different
places: the identity provider sent no groups at all, or it sent groups
that do not include the one granting write access. From the outside the
two look identical, so the dashboard now says which it is and what to
do about it, and the sign-in logs the same thing server-side.
The groups are carried in the session for that purpose, capped so the
cookie cannot grow with someone's group membership. Group names are not
secrets, and a support conversation that starts with the actual claim is
a thirty-second fix rather than a guessing game.
