Quantum Incompleteness: An Ontological Interpretation of Quantum Mechanics Based on Irreversible Constraint

Quantum Incompleteness presents an ontological interpretation of quantum mechanics in which physical systems are objectively under-specified prior to irreversible interaction. The theory rejects hidden variables, parallel worlds, and observer-dependent collapse, proposing instead that definite outcomes emerge through irreversible information-theoretic constraints that physically exclude alternatives. The wavefunction is treated as a real but non-material structural entity that defines the space of admissible outcomes rather than pre-existing values. Measurement, entanglement, classical definiteness, and the arrow of time are unified under a single completion mechanism grounded in thermodynamic irreversibility, while preserving the standard mathematical formalism of quantum mechanics. This work is empirically equivalent to standard quantum theory and is intended as a foundational clarification of what quantum mechanics describes rather than a modification of how it computes predictions.
