From Tardis Wiki, the free Doctor Who reference
Space / Time is an odd case because we have no need to define whether they're a two-parter, but if we do so they can be cited as one story on in-universe pages.
Per its premise there is no guest cast, so the same exception as Heaven Sent / Hell Bent applies.
