Yeah, Maillol was wondering when or if Asmodia would point that out. She's been a favorite of his, but he was starting to doubt her competence there.
If it gets to that point, Cheliax is going to have a military emergency with Nidal - maybe not even a fake one, based on some recent intelligence - and ask Keltham to accept somewhat extended payment terms on a putative plan where Cheliax withdraws wizards and resources from a lot of other things, like school academies, and makes a truly massive push to scale up spellsilver production and do a lot of mining and catch up on part of the demand backlog and maybe not die during the war with Nidal. It will be clearly said to Keltham that this is not sustainable.
The books can't be false, but the Queen can pass an act legally creating a separate calendar for Project-related companies which runs twelve times slower for the duration of that year, making all the dates showing massive production over one month be legally correct.
Asmodia needs to keep in mind that her superiors are not, in fact, complete incompetents. Lrilatha and Abrogail Thrune put some cleverness into this.
