A Self-Causal Single-Origin Universe Framework

This technical note presents a conceptual framework for a self-causal, single-origin universe that evolves without external parameters or ongoing intervention. Rather than proposing new physical laws or speculative mechanisms, the work focuses on interpretative minimalism: identifying which assumptions are strictly necessary for a consistent cosmological description. The framework assumes a finite initial configuration and emphasizes internal causality as the sole driver of cosmic evolution. Apparent fine-tuning, large-scale structure, and long-term persistence are interpreted as emergent properties of internal dynamics rather than outcomes of external control or optimization. By explicitly adopting a zero external parameter principle, this note aims to clarify the distinction between physical description and interpretative overlays often introduced in cosmology. The work remains compatible with general relativity and does not commit to any specific cosmological model. This document is intended as a structural reference rather than a definitive theory, and may serve as a conceptual baseline for future discussions on autonomous cosmologies, discrete spacetime models, or interpretations of simulation hypotheses.
