What happens if the battery pack is unplugged accidentally on the Vision Pro

While using Vision Pro, there could be a situation where the battery pack is yanked from the device by a door handle or just a wave of the arm, what happens in those situations, does the Vision Pro just turn off instantly or is there some sort of back up. I am curious, because when building productivity apps like Word, whether data would be lost. If there is a backup, is there a notification that developers can use to react and save current state and other data?
