Boundary-Induced Collapse as the Ontological Foundation of Quantum Measurement Formalisms

Modern quantum measurement theory relies on successful but ontologically incomplete instrumental formalisms, such as decoherence theory, Lindblad dynamics, POVMs, and consistent histories. While these frameworks describe the operational behavior of measurement, they lack a structural account of outcome uniqueness. This paper demonstrates that Boundary-Induced Collapse (BIC), derived from the Theory of Axiomatic Necessity (TNA), provides the foundational ontology from which these formalisms emerge as partial projections. Within this framework, collapse is redefined as a deterministic structural minimization governed by the realizability functional F(psi,B), where B represents the boundary operator encoding experimental and environmental constraints. We establish explicit mathematical correspondences showing that standard quantum formalisms are operational shadows of an underlying boundary-controlled necessity. Quantum randomness is thus characterized as an epistemic consequence of unresolved boundary degrees of freedom, rather than a fundamental stochasticity. Finally, we prove that boundary projections form a complete POVM resolution of identity, naturally recovering the Born rule through boundary ensemble averaging. Reader’s Guide: Given the high density of the TNA formalization, readers primarily interested in how this framework resolves standard quantum paradoxes (Bell’s non-locality, unitarity, and the Born rule) may find it efficient to first consult the FAQ/Appendix E. This section addresses the most common interpretative frictions by deriving them as structural consequences of the boundary-induced model, providing a clearer context for the technical derivation in the main body.
