4th tab. I'm looking for general feedback, anything is appreciated!
Technically, aside from the nitpicks identified above, this is all right stylistically. No major complaints, though the dialogue in the interview is a bit strange. The civilian seems to me like he'd be more worried and fearful in the beginning if he thought he was going to sent to a black site or something. Nothing egregious, but it could use a little work to sound more like a person.
In terms of the narrative, this is a lot of work for not a whole lot of payoff. The interview doesn't really tell us anything that we didn't know already from the description, and the second addendum could have easily been omitted with the "changing speeds does things" dropped in a little more organically elsewhere. The experiment log takes more length to establish the aforementioned speed thing, and by the time I've finished that it's been kind of a slog.
The reveal, like the rest of the article, seems heavy on filler, and I found the memetic agent thing to be borrowing too heavily from SCP-2000. Especially with the ending you've given it.
Add in the compulsion effects, the light "crazy to death" flavor, and the somewhat formulaic "interview log-experiment log-big secret reveal" setup, and this all feels like the shell of something, but not anything in its own right.
