tbh, getting something from that data would be a little plot convenience. They decided to put Koko's old frame in the loft just recently, espionage happened then they take it back to workshop. Almost like digi forced that thing happen, which I think is out of his style. Also they mentioned the data was heavily encoded, which is weird for Koko's old frame. I say it's red herring.
Vulvamort gonna pull something before the expo, I am sure of it but if it's just that code I think it's cheap way to go.
Also, MC was the one who coded that shit, Artemis' frame more less built in that manner. As we know, Hunter did not followed that procedure since Vulvamort forced MC to discard it. So, cracking the data then merging that data with Hunter's code should take very long because even though when everything goes right, it took MC's lots of effort. All in all, I feel like that way is way below the story quality of this game.
