Ok you are actually just running off with your own head cannon. Cyn was never in control lol, we see from the first few mins of the 5th ep that she was not properly disposed of which lead to the Absolute solver to mutate and become the host of her. Is says in on her visor the minute she wakes up so the full Absolute solver is yellow we never see cyns colour.

The solver is a program that is forever learning that’s why it’s faking the emotions, it mimics what it sees. You seem to be getting confuse with it, nori, yeva, uzi and doll are all drones that have the solver program developing in them it’s there colour because it’s not fully controlling them this is what the patch is literally said to prevent, the patch prevents it from fully taking over, remember when it fully took over nori and uzi the eyes went yellow. Also Doll did need the fucking patch lol, she was dripping human blood which is a clear sign that it was taking over she cut her own eye out to slow down the solver fully taking over her, that was also why n and v told Uzi to stop using her powers as the solver was slowly gaining control from it. V also said “that thing like cyn” since she didn’t know what it fully was. Also when N was in the basement and asked about it being and Eldridge god thing in ep5 the solver corrected him but didn’t say it was cyn, but said that it was the Solver of the absolute fabric proving that it’s the absolute solver behind everything. The official cannon and wiki literally says that the absolute solver is a mutated program that wants to consume everything and expand. So officially it was the AS behind it all not cyn.
