The door can be held open, as both key cards always promised

MASTER KEY and PICK LOCK each read: "You may 'hold the door open' for
others, if you wish" — and the engine always slammed it at end of
turn. Now the cast takes a hold param: the door stays unlocked past
the turn, for anyone, as long as its holder stands adjacent and
alive. A step away, a shove, a teleport, or a killing blow lets it
swing shut — swept after every command, since anything can move a
wizard. New state, new param: no old ledger contains either, so no
rev gate is needed.

The client offers a "hold the door open" checkbox when either card is
selected; a held door shows pale with a green jamb ("held open by a
standing wizard"), and the chronicle records the holding and the
shutting. Pinned: a held door outlives the turn and admits the other
wizard; walking away releases it.
