@J.G.Montoya looked at PAI, decided he could build it better, then rebuilt the entire thing from scratch with a cleaner codebase and first-class opencode support. He kept all five of PAI's structural primitives. That a ground-up rewrite preserves the same architecture is the strongest argument that the architecture is correct. @J.G.Montoya looked at PAI, decided he could build it better, then rebuilt the entire thing from scratch with a cleaner codebase and first-class opencode support.
