I notice a lot of archaic and off-kilter wording in the conprocs.
SCP-4237 is the joint designation for both SCP-4237-1 and SCP-4237-2.
this belongs in the description
No less than 4 members
"At least 4" is significantly clearer
kept above a minimum of -32°C and below a maximum of -17°C
could condense that to "kept between -32°C and -17°C."
don't have a ton to say on the description, but
including extreme temperatures and conditions such as: Blizzards, thunderstorms, tornadoes and heat waves.
the colon is unnecessary there
no notes on the first collapsible
second collapsible, tho - it feels unnecessary. the blackbox log doesn't really add anything to my understanding of the anomaly given that you've already explained how it escapes, and it doesn't push the story forward either for the same reason. same thing with the mtf log. its alright dialogue, sure — but would the article's narrative suffer from it not being there? what does it tell us?
rest of that addendum is fine
the last interview, though - it really stumbles here. it falls into a Cliche Pit and uses the trope of "foundation interviewing person giving flowery cryptic non-answers". straight up it's just not fun to read, and whatever narrative it puts forth are kind of buried under that. on its own its one thing but this is like, an exceedingly common problem on articles here, especially older ones, so it's worth mentioning.
with all that said, this isn't an aggressively bad article or anything. its decent for a first article, it just has a lot of fat that could be trimmed to make the execution tighter and leaner. the clinical tone is generally competent and the use of blackbox logs is an interesting technique, so props on that.
