General Transfer-of-State Model (GTOSM): What Is Measured in Quantum Mechanics — Bosonic Duality Eliminated by Boson–Fermion Asymmetry

The Measurement Questions (structural framing) Any complete account of quantum measurement must answer four logically distinct questions: What is measuredWhich physical identity component is registered in the measurement event? Pre-measurement evolution(context for the target measurement)What interactions occur between initial preparation and the designated target measurement, and how do they reshape or constrain the admissible evolution of the wavefunction? Where is it measuredAt which spatial location does the registrar event occur? When is it measuredAt which lattice tick does the registrar event occur? These questions are independent in definition but coupled in prediction: prior to realization, specifying one of {where, when} necessarily leaves the other probabilistic. Scope of this work This work resolves Question (1): what is measured. We show that: Bosons cannot be measured directly. A “boson measurement” is always the measurement of a fermionic non-optimal transfer induced by bosonic interaction. All registered outcomes are fermionic registrar events. Bosonic wave–particle duality is therefore not fundamental, but an artifact of fermionic detection. Questions (2), (3), and (4) — including explicit space–time prediction and pre-measurement evolution (e.g. elastic recombination) — are deferred to follow-up work.
