# It's important to keep AuthUser and User in sync. When we create an AuthUser
# (e.g. through the registration process), we create a matching User, too. And
# when the AuthUser's name changes, we update User to match.
#
# TODO: Should we sync deletions too? We don't do deletions anywhere in app
# right now, so I'll hold off to avoid leaving dead code around.
