CGR / COLOSSUS: A Reproducible Diagnostic Framework for One-Cell Sensitivity Analysis in Cosmological Inference

This release presents CGR / COLOSSUS, a fully reproducible methodological diagnostic framework designed to evaluate one-cell sensitivity and functional misspecification effects in cosmological inference pipelines. The framework does not propose a new cosmological model nor claim to resolve existing cosmological tensions. Instead, it provides a diagnostic tool to assess the epistemic stability of inferred results under minimal structural perturbations. The repository includes executable code, methodological documentation, reproducibility protocols, validation notes, declared limitations, and licensing information. All components are versioned and designed for transparent reuse and auditability.
