[!FRAUD SPOILERS ALERT!] Do you think V1 is running on Nocturnal OS or it's a completely new/different OS?

At some point in, I think it was 8-2, we could see presentation about types of OS. Smile 1, Smile 2, and Nocturnal. Nocturnal is said to consume way too much blood to be sustainable, but is self-adaptive to unknown limit and must NEVER be used... Which fully checks out for V1. It consumes indefinite amout of blood and it adapts to almost all situations.

Also, on the side note, do you think that terminals run on Nocturnal as well, but just hide it?
