The D-class was in the same room, yeah, but the only guy we see observing the event seemingly cannot describe it other than in the vaguest terms ("we lost a D-class", "Bentham didn't do it"), which was intended to imply that, due to the effect of the SCP's anomaly on their perception, they can't actually tell exactly HOW it killed the D-class - mostly because their brain keeps trying to reject the idea that it DID, since it is, after all, a normal rabbit. But it WAS clearly something messy - the room needed "cleaned and fumigated" - so while one explanation could just be "the Wolpertinger tore their throat out" and therefore it would be safe if kept at sufficient distance, an equally valid explanation could be "the poor sod's head exploded as soon as they accurately described the Wolpertinger".
I was intending to convey that Wagner (and/or anyone else who saw the incident) suspected, while being unable to tell for sure, that it was something closer to the latter, and so felt justified in going to the absurd lengths necessary to get the procedures edited to include a bit about never letting anyone who didn't know about Wolpertingers get exposed to it.
On reflection, yeah, that's very opaque. My bad.
I guess rewriting the article to be in-universe written by someone who COULD accurately describe the thing safely but CHOOSES not to for the sake of avoiding undue stress to other personnel, rather than the current set-up where it was written by someone who was getting as close to describing it accurately as the anomaly would let them, might work better at least in terms of being easy to understand, yeah.
I don't personally like it as much, and I feel like I'd still have to drop some of my favourite ideas. Like the fact that the handler needs to be someone who doesn't know what they're handling in order to prevent them going "sure, this is just a normal rabbit, of course you can let it out", while simultaneously being sufficiently loyal to the Foundation to not question their orders AND sufficiently busy, intimidating and hard to contact to deter researchers from trying to explain to them the ridiculousness of the situation as they see it - a set of criteria that basically rules out most personnel except members of one of the scarier and more fanatically loyal MTFs. If there's a way for certain people to safely observe and accurately perceive it, the handler would logically just be one of those guys, which is less interesting.
But if I can't think of an alternative solution any time soon, I guess I'll try rewriting it to be more like that.
Thanks.
