AAIS Phase III: Constraint-Based Emergence of Physical Law from an Information-Saturated Substrate

AAIS Phase III is a fully constraint-based theoretical framework that investigates the emergence of physical law from an information-saturated substrate. This phase does not introduce new forces, particles, dynamical equations, or phenomenological parameters. Instead, it derives the necessity of known physical structures from global consistency, accessibility constraints, and structural closure conditions imposed on the underlying informational substrate. The framework treats spacetime, matter, interaction, probability, and scale separation as emergent relational projections rather than fundamental primitives. All established physical theories are recovered as limiting or projected cases without modification of empirically validated results. AAIS Phase III is structurally closed, internally self-consistent, and explicitly falsifiable. Any empirical observation requiring violation of global consistency, accessibility bounds, or ratio invariance would invalidate the framework. This repository contains the complete Phase III construction, including: - A formal README defining scope and constraints, - An executive structural summary, - Six core structural modules, - A final synthesis establishing closure, - Three open disks addressing stability, margins, and future testability. The work is intended for researchers in theoretical physics and foundational studies who are interested in constraint-driven, non-phenomenological approaches to physical law. No acceptance of speculative models is assumed. Phase III is considered theoretically complete. Extensions, simulations, and phenomenological mappings are deliberately deferred to future phases.
