Forecast Cone: A Grand Theorem for Computable Software Evolution

TL;DR This article starts from the ForecastCone in Software Field Theory (SFT), then reads modularity, technical debt, review, governance, and learning as parts of one research program. The goal is simple to state: Make it possible to see what futures a change opens, close dangerous futures early, and shape the development environment so good futures become easier to reach. If this theorem-shaped program works, architecture, technical debt, review, governance, and AI coding safety can all be reread around the same object: the ForecastCone.
