You want:

login from elsewhere to log out the same user anywhere else

It wants:

any login by the same user "claims" the user's session

so, if you add in your root auto

if ($c->user_exists) {
  unless ($c->user_session->{sid} eq $c->sessionid) {
    $c->logout;
    $c->forward('/auth/logged_out');
    return 0;
  }
}

and in MyApp

sub set_authenticated {
  my $self = shift;
  $self->next::method(@_);
  $self->user_session->{sid} = $self->sessionid;
}

then you should pretty much be done.

So far as I can tell, this is perfect for you. You just sometimes get
persistent session data as well (it warns against fastmmap because in the
"persistent session" use case fastmmap is lossy - in yours the lossyness
is irrelevant, you don't care about the persistence feature)
