The first part is fantastic, but the second part kinda let me down.
I get that the second part is supposed to explain everything, but I definitely don't think its needed at all. The first parts complete inexplicableness lends a perfect amount of mystery and fascination to the horror of the whole situation - the description is fantastic, as well.
The second part isn't necessary. If it were up to me, I'd just delete the entirety of the second part. Better to leave it up to interpretation to what happened. If you could, add the part about the pomace because that's a beautiful segment, but other than that it doesn't add much to the enjoyment of the article.
Still, when I was reading it I looked away as the lady climbed in and crushed herself, because your description was really chilling. Fantastic work.
Minor issues:

RPC-###'s primary anomalous effects begin when RPC-###-1 is in the presence of a female human being, hereafter RPC-###-2. Instances will invariably desire to:
RPC-### is the designation given to two concomitant anomalies, designated RPC-###-1 and -2. RPC-### is harmless
The cocmitant part is unneccessary imo, you can introduce RPC-###-1 as RPC-###, and then make it create the crazy ladies which are -1 instead. Personally I think it'd flow better that way, but I'm not sure if that's a stylistic choice or not.
Also, quick tip, the term "appears" is generally a bad thing to use. I get that it's an anomaly, but the less syllables and words you use to describe the same thing, the better.
Also, even though its a format screw, there are some issues with clinical tone you should address, such as when they say that they're using a lot of materials to try to open the chest.
The only main issue I have with the first section is that it's a little unclear what the anomaly does - the whole putting yourself into the box thing isn't explained at all, but that's part of the format screw entirely. If you want to keep some of the second parts reveal make like, an email at the end of a memetics specialist talking about the anomaly, maybe? But I woulnd't reccomend revealing too much - if you didn't have the second part, I'd be thinking about this article for days trying to figure out what was going on.
Tremendous potential in this piece - second part's a lil extra though.
