Torqued Substrate Theory — Quantum Mechanics (Expanded Module)

This document presents the Quantum Mechanics Expanded Module of Torqued Substrate Theory (TST). Quantum mechanics is treated as a projection-limited descriptive regime. All standard formalism and empirical predictions are preserved, while ontology, measurement, superposition, entanglement, and collapse are reframed as constraint-realization and projection-accessibility phenomena. No new parameters or empirical claims are introduced. Regime boundaries and diagnostic criteria are made explicit.
