Quantum Mechanics as ACO Atomic Continuum Ontology - Partial Closure

Quantum mechanics is empirically powerful but ontologically unsettled. Its formalism predicts with extraordinary precision, yet its dominant interpretations remain organized around four inherited pillars of illusion: indeterminacy, superposition, entanglement, and the observer problem. These are usually treated as separate mysteries. This report argues that they arise from one deeper misinterpretation: quantum mechanics describes the ACO partial-closure band, the regime in which coherence has entered measurable disclosure but has not yet completed classical closure. From this perspective, a quantum system is not a failed classical object, nor a mystical entity occupying contradictory realities. It is a partial-closure object. Indeterminacy appears because closure is incomplete. Superposition appears because multiple closure pathways remain unresolved. Entanglement appears because vector outcomes disclose from a prior bivector relation. The observer problem appears because physics has not defined the closure-selection function. This report reconstructs the four pillars of quantum illusion through ACO partial closure, coherence selection, and bivector relation. Quantum mechanics is not rejected; it is ontologically relocated. Its formalism is interpreted as the mathematics of partial-closure objecthood rather than as proof of ultimate randomness, literal multiplicity, spooky action, or magical collapse.
