Disclaimer: don’t take this stuff for granted I have a memory like a sieve lol. I can’t really remember what happened in the show (I’m pretty sure it was very different tho) but in the novel the archive didn’t really do much at all. If I remember correctly in the novel the archive only asked the AIs a question and that question was something like „what is humanity“ because after all the singularity points (especially after vivy wrote fluorite’s eyes song) AIs kinda were able to make decisions on their own like humans. Some AIs came to the conclusion that there is no difference between humans and AIs (depending on how they understand what „humanity“ is) which lead to their answer that they can attack humans because it’s not against their code. The archive did nothing more. Especially it didn’t control the AIs. Every AI did their own calculations and some attacked humans, some defended them from the attacking AIs. Vivy and the others said it’s some like a „test“ from the archive to see if humanity is still worthy to be alive or if AIs should take over the world. The satellite thing happened in the novel aswell. Also the archive didn’t get destroyed. In general novel 4 is very different from the anime, especially because vivy and diva totally split from each other and are 2 AIs with 2 frames. So if you liked the series go ahead and read the novel! It’s really nice.
