I agree with that part of things but why is that name the one that's used when we enter the Archive? I would assume in order to gain access to the archive, one would have to have an entry key of some sort or another way of identifying one's self to the computer system. The system wouldn't just go, o hai Dr Shim, to every entity that would enter the facility and in fact even alerts you to intruders entering. Or is Dr Shim's access codes just what the ghost stumbled upon while breaking into the network to open the door?
