Haha, I’ve thought about this from time-to-time, I figured someone would bring it up here eventually!
I generally agree with your encoding thus far, and I also agree that the throughlines are tricky. Because of the short length, it might just be Concern deep.
It doesn’t strike me as an OS Situation story - how is everyone externally ‘stuck?’ Maybe I should back up - what is the source of OS conflict, without talking about domains / throughlines? What’s affecting everyone?
