First and foremost I'd like to congratulate you on breaking the Memotic Article Curse. Holy shit, it took a looooong time to get a genuinely great one that wasn't written by exactly Tarbolin.
Special praise for the concept. It's a pretty clever usage of memotics that doesn't have the overhead you'd expect with having to learn the specifics and jargon associated with the mechanic, which I especially appreciate because all that stuff is a bit rusty in my head (I couldn't recall what exactly a memotic ground was) but still was able to follow along perfectly. I imagine this to be a pretty great light-introduction to memotics if you don't know anything at all about it.
The interviews were all believably written and very elegantly told a long span of time with plenty of detail. It's remarkably easy to imagine how things worked for all the people involved and it gives the Authority a somewhat homey (ironically) feel. Great job on that, the organization itself feels very human, which is an achievement considering how the plot revolves around its stringent rules.
I do think there's some more specific issues that have an additive effect throughout the article. E.g.: the first interview develops so the characters aren't aware of what's going on, which makes perfect sense chronologically, but it means that all it's revealing about 973 are things we've just learned from the description. If you're not sold on the characterization or don't especially care for the characters off the bat, it's going to feel like twiddling your thumbs waiting for them to catch up to what you already know, so I think you might benefit from removing a bit of explanation from the Description. That way we're learning how it works together with the characters.
I'm also not very sold on Incident 973-1. I get why it's there logically and what it establishes is important to the article, but the events themselves aren't all too interesting, which is a downer because the incident formatting gives it a kind of visual pomp that communicates "something important's going to happen, pay attention". It might be better served by a more creative spin on the concept — like, IIRC the memotic plane might not necessarily align with the passage of time of the physical plane, so you could have 973 predicting bits of the future through the past. That could be funky.
(Also the incident says 973-3 — do you maybe mean 973-A3?)
Another problem (which is probably an easy fix) is that we don't really know what the circumstances of confinement for 973's civilian family are — like, we hear they're "with the freaks", which sounds like an exaggeration, but it'd be easier to relate with the reasons behind that exaggeration if we knew the actual confinement they were in.
Finally, I think the length ill serves the characters. 973 himself is in a really interesting position considering he's what got his family under Authority seclusion basically forever, and we never really hear him comment on that. He seems like a really caring dude, this sort of thing might've affected him a lot. Ditto goes for Sculptor, she's in a fascinating position and we only get to hear about her and her relationship with 973 in hindsight.
Got a bit out of hand writing that — still a great article that well accomplishes its concept. Good luck on the contest!
