MA-U v20 — Cosmologie informationnelle : socle conceptuel et cadrage méthodologique

This publication presents MA-U v20, an information-based cosmological framework. Version v20 establishes the conceptual foundations, axioms, and methodological scope of the MA-U model, motivated by recent observational tensions in cosmology (e.g. early massive structures reported by JWST). This release is conceptual and methodological in nature. Computational code, numerical analyses, and implementation details are intentionally not included and remain internal. Earlier versions are preserved for reference purposes.
