Watched 'movie_043583.mp4' (catchy name, by the way!). Left with some questions/comments.
I feel kinda like I'm only getting half of a conversation, or maybe I'm just missing something obvious... but, what is the purpose of the topmost hip roof? Is there some problem with existing structures/designs that it is addressing? Why do we need some many roofs over the same area? At first glance I assumed it was to allow windows underneath the overhang, but that's clearly not the case in this plan...
It does look like a pretty dark structure; if the wing wall areas are roofed over, a round door added to the outside, and then there is a wall with door between them and the main room... drastic reduction in light inside the main room, no? Could those main room/wingroom walls be made mostly transparent, to maximize light and apparent openness?
Does 'capping wall' imply anything specific in your videos?

I do have thoughts on some of these topics. In no particular order, the concept of turning the rectangular space to expose the corners and have interior angles maximizing contact with the thermal mass is sound. It potentially gives more interior volume with less weather exposure, while still letting light reach directly to every part of the interior. I don't understand the value of making two straight "tunnel" exits from each corner; you would get significantly more light yet not much more heat loss by letting light in from all angles at the corner.
The plan of covering the wing walls with roofs, and only a few oval openings, would turn the interior into a cave and for many people this would cause claustrophobia or at least much less comfort and enjoyability. The wofati is not supposed to be just a survival shelter but an attractive place to live. If it is not attractive in terms of internal comfort to average people, it will not see long use. I get the impression that Paul wants to get to a structure that is so close to invisible that there are no straight line openings to the exterior. This is fine, but keep livability in mind. The rough primitive interior look is not inherent to the concept of a wofati; one could be finished to look quite "civilized" on the inside without altering its principles.
Why does a wofati need any hip or shed roofs over its internal flat roof/ceiling? The mounded earth (kept dry for insulation/mass)if sloped correctly on top will do the same thing when covered with a waterproof membrane as a wooden roof structure would do, at much less cost.
Finally, it was painful to see a few ants discuss layout of their small structures and orienting windows every way but south. Proving the feasibility of a thermal flywheel concept is great, but if you plan to live in a structure, it only makes sense to build in multiple routes to warmth and comfort. Also, do not minimize the psychological importance of direct sunlight inside your dwelling in the cold winter months. I grew up in a house designed by my mother in the late 1950's which had south-facing windows and clerestories protected by overhangs, and the feeling of basking in the midwinter sunlight in the middle of the living room floor has stayed with me ever since.
