The Ontology of Xu and Shi: Free-State and Constrained-State Projections Across Scales

Traditional frameworks analyze virtuality and actuality in isolated domains, lacking a unified, first-principles foundation that bridges microphysics to macro-civilizational evolution. This paper develops The Ontology of Xu and Shi within Energy-Efficiency Theory (EET), grounded strictly in Core Rules v5.7. We define Shi as the functional-layer projection of constrained-state energy---structural maintenance power locked behind topological barriers. \textbf{Xu} is the functional projection of free-state energy flux---unconstrained responsive and dissipative power. The universe is a relentless cycle between these two states: condensation (Xu $\rightarrow$ Shi) via Algorithmic Submersion, and dissolution (Shi…
