We formulate superposition directly from the linearized visible action of the b frame-work. Starting from the already established visible action, we expand the φ and β sectors around a stable visible branch and diagonalize the quadratic visible sector into propagatingnormal modes. Quantization of these action-derived normal modes yields a visible Fock-spacestructure in which coherent linear combinations arise naturally. In this way, superposition isidentified as the coherent linear combination of visible-sector excitations prior to environmental branch selection. The result is intentionally bounded to the quantized quadratic visible sec-tor and does not yet constitute a full nonperturbative derivation of all possible superposition phenomena in the complete interacting theory. This research identifies superposition as a natural consequence of the coherent linear combinations of excitations within the visible-sector, established prior to the environmental branch selection discussed in previous installments of this series
