We propose a thermodynamically motivated interpretation of quantum mechanics, where the wave function represents a statistical projection of unresolved energetic interactions across nested, non-equilibrium structures. Within this framework, quantum indeterminacy arises not from fundamental randomness but from practical inaccessibility of deeper energetic degrees of freedom. The model offers a natural explanation for phenomena such as zero-point energy and vacuum fluctuations as local thermodynamic residues of hierarchical energetic coupling. This interpretation aligns with the epistemic perspective of the wave function and provides a new bridge between statistical mechanics and quantum foundations.
