Identifiability of Fifth-Sector Electromagnetic Operators Under Null Experimental Controls
A design-theoretic extension of Maxwell-compatible projection models
01 / Abstract
Abstract
The existing JMP0X1B projection papers classify speculative fifth-sector electromagnetic residuals by gauge consistency, scalar readout, boundary flux, and experimental null signatures. This paper asks a narrower question: when can two candidate residual mechanisms be distinguished at all? We formulate operator identifiability as a rank and conditioning problem over a matrix of predeclared controls. Pressure, polarity, shielding, inversion, scale, dielectric substitution, modulation, and edge smoothing become transformations acting on a vector of observables. A useful experiment is one whose transformation matrix separates candidate mechanisms before the apparatus is built.
