Observation as Access: A Quantum Traction Theory Dissolution of the Measurement Problem

Abstract

When does a laboratory record belong to the source, and when does it belong to the measurement camera? Source, physical access operation, and laboratory camera. The paper-native master equation keeps the source, the physical access operation, and the laboratory camera in their proper order: \[ \boxed{ \mathcal O_{\rm lab} = \mathcal C_{\rm lab}\!\left[\mathcal P_A(\rho_{\rm src})\right], \qquad \frac{\partial\rho_{\rm src}}{\partial\mathcal C_{\rm lab}}=0. } \] The central access law inside that map is \[ \Delta X\,\Delta P\ge\frac{\hbar}{2}(1-\eta), \qquad \eta=\operatorname{Tr}(\rho\hat M_w), \qquad [\hat X,\hat P]=J\hbar(I-\hat M_w). \] Here Mw is a bounded central projector and η is its state weight. A laboratory visibility is a different object: a nonlinear ratio of terminal Fourier coefficients. Version 9.0 derives their exact bridge for a sector-preserving matter-wave instrument: \[ \boxed{ C_n^{\rm obs}=(1-\eta)C_{n,u}+\eta C_{n,a}. } \] It proves that one fringe visibility does not identify η, even when the ordinary fringe, equal throughput, and common phase are assumed. The familiar attenuation rule Vobs/Vu = 1−η is recovered as an exact special branch only when the aligned sector has no analyzed first harmonic and every camera term is fixed independently. The public Pedalino nanoparticle archive is then executed as a reproducible camera audit. Its selected power row rejects a constant visibility multiplier, but it does not contain the central projector or sector-resolved calibration required for an Access-Law η verdict. The paper therefore preserves the data result and blocks both a false confirmation and a false falsification.
