The writing quality of this is overall very good. There's a few minor things, like that there's normally parentheses surrounding the mobile task force ("name"), and that the foetus in foetu would probably benefit from a footnote with a little explanation of what exactly it is.
Some lines in the description are great and really got me hooked right from the start. Things like the "birthing house" showed me what I could expect in the best way possible. I also feel like I got a lot of information about the group without being bored by too much text.
One extremely minor qualm I have with the notes from Isabelle is with the approximate area of 47 metres. Since 47 is prime, I struggle to see it coming out from an approximation of an area, and would probably change this to 50 honestly.
Oversight Committee
Huh, I've never heard of this. This isn't really a critique, more just me being interested about what exactly this is.
they use the babies to feed the kiraak
Missed a capitalisation for Kiraak here.
I'm a little unsure about the transcription of Delta's accent/dialect here, though it's not something intrusive enough to substantially affect my vote. I'm also a little unsure about the formatting of events etc. in the MTF Log, but that's another personal note (I prefer what I've used in SCP-4835. The log overall is great though. Dialogue is realistic and it includes that clinical description of gore that I love so much. I'm unsure about the blackbox though, am I missing something that would justify it?
Overall though, this is great. I was interested all the way through, even with my admittedly limited knowledge of Sarkicism (your crosslinking was great for me). I'd say that the weakest part is the personal log from the start, though I understand its necessity in the piece and it doesn't subtract from the whole. But yes, a great story with some incredible and horrific description and implications are totally enough to get my +1 here.
