Many times I've run across a situation where a knee brace supporting a floor loaded bent girt or connecting girt caused more problems than it solved. For example, if the knee brace picks up loading from the beam, the compression forces in the brace can become quite high. This, in turn causes tension and prying shear in the girt to post connection. (Not to mention problems designing an adeaute house for the knee brace!) To avoid these complications, consider 'floating' your knee braces. Avoid houses of any kind. Create a regular single pegged connection in the beam. At the post, shorten the tenon, elongate the mortise and slot the peg hole in the tenon parallel to the grain. This will allow the connection to 'slip' under load and prevent the brace from doing any load-carrying. The downside of this is that the brace will offer no lateral stability to the exposed frame during raising. You'll have to make sure the frame is well guyed and temporarily braced until the shear walls are constructed.
