Set with the Sun
I read two lines before I panicked, lol. ("Oh, no.")
Yotsuyu and Fordola are a complementary pair. Following the popular fallacy of "villains are either true monstrous evil or made-monsters if not redeemable", depending on your own ethical epistemology (intent vs. outcome) they occupy opposite slots. They were written to inspire passionate opinions and debate, so I expected this week's discussion to be a wild ride.
And then, "I'm Yda." ("Oh no.")
And yet, in the end, I think I'm willing to defend this one.
Except for the part that says she joined the XIIth legion. She almost certainly joined the XIVth and ended up in the XIIth to her dismay. There has to be a near-zero chance Zenos yae Galvus and his force of close-to-the-throne Optimates made Fordola rem Lupis a Pilus Prior of her own cohort of their legion because it was there own idea rather that he inherited them from the XIVth and found them amusing to toy with.
EDIT: And Sounsyy just shot me some quotes of the Tribunus Militum saying as much, lol.
Rosenstrauch brings up a good point that I always try to highlight: there's a difference between an addition-retcon and a subtraction-retcon. If you add new information that you just made up and it reframes "what we knew before" so that it becomes "what we thought we knew before" - that's still retroactive continuity (additive). People hate subtraction retconning - resolving contradiction by straight up changing or deleting "what we knew before". Addition retcons are are a skill that this dev. team uses regularly, and often brilliantly. Half the time you're thinking, "Wow, they planned this all along!" ... They didn't; they addition-retconned it.
Anyroad, OP updated.

I think both Yda and Lyse are presented as quick-witted when it comes to fighting, immediate tactics, and emotional matters, and just about nothing else, lol. Even when we saw echoes of "the real Yda" in 1.0 (I say this because I don't think they knew they'd retcon her into Lyse back then), she had the same disposition.

It comes across as another odd retcon.
Is this accurate? If I remember right...
...even in 1.0, Yda was wearing a kagura mask and we just saw her neck and hair from unseen angles while her face was still covered. I read this story as saying the real Yda, beneath her mask, had a side-eye tattoo not unlike the one she got at the end.
