A vertical thinking tool that drills down from any observation to its irreducible foundation. Trigger it when you want to trace "why" instead of surveying "what else." It writes a descent through explanatory layers, each named and separated by the crack that leads deeper, switching frameworks as it goes (sociology drops into psychology, psychology into biology, and so on) until you hit bedrock: human nature, physical law, logic itself, or paradox. Output lands in an org-mode file. It's built for the moments when you're tired of lateral thinking and want to dig straight down through a single idea until there's nothing left to stand on. Good for finding out what you actually believe about something.
