Curious how so.
Well I’m still not very far in, but what it seems to be going on is that the plans seen in AOTC were planted to goad the Republic into an arms race. The novel begins a year or so into the Clone Wars, and the Republic is developing its own Death Star project having learned about Dooku’s plans after Poggle the Lesser’s capture (I think this might have happened in TCW, but I don’t remember). So the Republic isn’t actually using those plans, and in fact in this early section of the book they’re not even sure what sort of weapon the Death Star is actually supposed to support (enter Galen Erso and his kyber crystal research). They’re working largely from scratch, trying to avoid a Death Star gap.
