Okay, thoughts on the plans. TLDR, I don't really like any of them as a whole, though different parts are attractive.
First, I don't really think it's a good idea to overwork right now. That would be better done after Foundations opens up a bunch of new options. Other than that, I really don't get the point of stuffing a bunch of research backlog here of all places. Improving Mathilde's swording is a good idea with us wanting to prepare for the Iron Orc thing and other potential adventures, but all the non-personal improvement pure research-and-publish actions are probably better done at a less time-sensitive juncture. IIRC we still have two techniques to work on with Branulhune. AV is bigger, but I still don't see the point of doing it now of all places, when an Aqshy firebomb can do the same job if you want explosions and weaponization.
I'm fine with recruiting Adela, but if that's the case we should also do two other WEB-MAT actions for efficiency. As for the Waystone Project itself, I'm still for Gambler, so I think anything we want to test the Father on (Halétha, the Lady, etc) should be squeezed into one turn so we get more usage out of the Coin's other sides during other turns. House Tindomiel is still a good idea to recruit now, since I really doubt Hekarti is one of the daughters.
