Some awkward wording:
Foundation efforts to research on SCP-# began shortly after the organisation's formation.
The beginning of the sentence is phrased a little awkwardly. Perhaps something along the lines of "Foundation research efforts regarding SCP-# began…" would be better.
To date, known SCP-# population is excess of 1,000.
Missing the article before 'known'; also, could stand to add an 'in' after 'is'.
I find the basis of the article interesting, specifically with regard to the theme of misunderstood entities which gain an ambassador serving as a bridge of sorts between two worlds. The format screw justifies itself quite nicely in that regard; the reveal of the anomalous edits being the product of a former Foundation operative comes across as a logical, if not unsurprising, conclusion.
I feel as though something is lacking in the piece, possibly to do with the methodology of the former MTF agent. The strength of the article lies in that character, being set-up as this 'higher being' formerly entrenched within the Foundation. However, it's unclear by the end of the article why exactly this character decided to directly communicate with the Foundation. Simply because it used to be an MTF agent? I get its ulterior motives, but why pursue those particular methods? What is its game plan by presenting itself so transparently?
I have noted your grammatical corrections and dutifully applied them.

I would say that 1034/Kata is still aware of his duties to the Foundation while being a bodhisattva (a saviour being by definition). I have adjusted his lines slightly, to show these two duties and him adopting a Middle Way as his option (i.e. help the Foundation to relieve their suffering over the uncertainty of a Keter SCP).
Alright, that makes sense. It also seems to me that 1034 is willingly containing itself as a way of performing its duty to preserve normalcy, i.e. not waltzing out into the open and breaking the masquerade. So, its sense of duty/loyalty to the Foundation is one aspect of its pre-bodhisattva identity that persists, though I feel now as if the 'saviour' part is somewhat underplayed. Maybe there should be a sense of a fundamental misunderstanding between 1034 and the Foundation, considering that the former has been so transformed by the acquisition of dharma. I'm not too familiar with Buddhism, but I would hazard to guess that gaining dharma has fundamentally transformed 1034 in some way, perhaps losing some sense of humanity in the process. Perhaps there should be a sense of foreboding surrounding 1034, hints at grander plans towards achieving the Foundation's goals (involving other bodhisattvas?) that extend beyond its voluntary containments and helpful intel?
TL;DR: playing with the notion of a godlike entity with simple intentions which inadvertently threatens to supplant the Foundation's own authority in the noble/foolish pursuit of the organisation's goals would be an interesting angle to explore.
