KEFE OF: Oscillatory-Field Representations - Mode Decomposition, Generalized Spectra, and Threshold Response

KEFE OF establishes the representation discipline for oscillatory phenomena in the KEFE publication suite. It distinguishes the real oscillatory layer OF-A, the conditional quantum/Hilbert-state layer OF-B and the averaged morphological layer OF-C. Source-driven nonlinear structural transitions remain part of the model-owned M/OF-A dynamics; OF-B becomes applicable only after a defined quantum-tunnelling gate is satisfied. The paper derives generalized spectral, symmetry, polarization, response and propagation constraints, including the exact mode decomposition. It also separates structural admission from transfer through existing support and distinguishes longitudinal, transverse and twist modes only after a rank-three spatial gate.
