Is this all traversable by the player right now?

Yeah, so like I said, this is obviously in the Editor. So if I hit Control-G, for example, I'm actually in game now.

You've switched the AI layer off so we're not in a world of chaos.

Yeah, so right now, this is just as it's intended from a visual and artistic standpoint. Obviously, the level is fully traversable and doors all work and everything. But one of the things is that AI is obviously an ongoing process, and obviously, live demoing at this point, anything could happen. So we're just trying to save ourselves a little bit of pain right now from showing too much stuff, basically.
