Thanks Brad for the implementation explanatin but
I'd rather need a
document outlining the expectations for user-facing functionality.
I just had to separately and manually login three times (on Meta, then on
Wikipedia, then on MediaWiki.org
) in order to be logged in on most wikis. I
don't find any page explaining whether it's normal for global login to
require entering my password 3+ times. If it's expected and documented, I
can stop worrying.
The expectation for single sign-on is that you sign-on a single time and
then you are signed on everywhere. If that's not what happens, feel free to
file a bug, ideally with a HAR file or something equivalent.
(I think there is one scenario when you need to login manually: when
visiting a wiki that's not included in the autologin domains while being
logged out, then logging in elsewhere, then visiting it again. The "user is
logged out" cookie gets set on the first visit, so on the second one no
autologin is attempted. But that should be very rare as Meta, Commons, and
all the not *.wikimedia.org wikis are autologin domains, so this can only
happen on exotic projects like outreach.wikimedia.org
