I think building a ship to escape is infeasible until we deal with the Mechanicus, so we're better off ignoring that design action until that's done.
I think maybe 2 actions on research, 1 on building and 1 on diplomacy? Last could just be more research, but if we bring in Victan he could help with the subversion of the Mechanicus acolytes.

--[] Yes
I figure we're not going to get one golden bullet for dealing with the Mechanicus, so it's best to stack multiple things in our favour. This gives us 1650 BP per action, so next turn we can put two actions in Construction to build an Underground Medium Void Shield installation and have 300 BP left over for shuttles and Trade Goods.
For research this'd finish 5 different tracks. Stealth shuttles are important to start throwing stuff into space, including eventually a spy satellite or two so we have better eyes on the ground, Improved passive stealth should help with fighters/assault shuttles, which I feel would be helpful when taking their station and if the fight goes loud and we can't hack all of their orbital satellites. CBH redux is a low hanging fruit, and Secrets feels a bit expensive for what it does but reducing the chance our own bots can be hacked is probably worth it.
For diplomacy I'm torn between further subversion and trying to coordinate more with the Denvan's. The former feels more urgent if we go for an education focus, but then we'll be taking an action next turn for them anyway so the latter may be more efficient.
