Not that I'm aware of, though at least one person has voiced the suspicion they're some kind of plant in the office. Her CV is bullshit though, I do know that much.
And yeah, photographic evidence was taken. And as it turns out, she is keeping daily logs on everyone she is handing over to (foolishly, she is keeping that notebook in the office, which IMO tends to suggest she's not - unless this place is hiring bargain bin corporate spies, which is entirely possible). Not just logs of information, assessments and appraisals of staff members, including myself.
I also know, from that log, that a minor complaint I put in, confidentially with my own manager, was revealed to her (information about student rooms on handovers was incorrect, meaning I had to double check everything with our more extensive paperwork before actually doing it, which defeats the point of a handover. It's not super-serious, but I asked her in an email just to take more care with the numbers, she never responded and kept making the same mistakes, so I bumped it up the chain like you do).
So maybe that's the point of her craziness. She doesn't like the fact that she's trying to be all "I'm super efficient and look at me create useless reams of paperwork every single day because fuck the rainforest" and I'm all like "there isn't actually a 36F room in this building" and "stop losing master keys plz".
