Closure Theory–ACORN Framework Current Canon and Guide

This document summarises the current state of the Closure Theory–ACORN programmeand serves as a guide for readers entering the framework for the first time.It is not intended as a proof of any specific result. Rather, it records the principalstructures, definitions, insights, and active research directions that have emerged during thedevelopment of the theory.The central purpose is pedagogical: to provide a clear front door into the ACORNformulation of Closure Theory, especially the three-domain architectureT ↔ t → o,the distinction between transformation and projection, the two ACORN fibres, the rel-ativistic invariant, the canonical ratio ρ, and the principal observable channels associatedwith mass and charge.Throughout this guide, terms such as “if correct”, “within the framework”, and “toward”should be understood in their ordinary scientific sense. Many of the ideas described hereremain active research programmes rather than established results of mainstream physics.
