The eight-dimensional compactification manifold K₈ = (CP² S²) w (T²/Z₂) ^Spinᶜ of the Master Equation framework contains a T²/Z₂ pillowcase orbifold factor characterised by two independent length scales and four Z₂ fixed points. Mitochondrial cristae architecture, as revealed by electron tomography and cryo-electron tomography, exhibits a structurally analogous geometry: each crista forms a three-dimensional lumen with one narrow dimension (the inter-membrane gap, ~20 nm), two longer dimensions (the lumen length, ~200–500 nm, and the ridge depth, ~100–300 nm), and narrow junctions connecting the lumen to the intermembrane space. This paper establishes the geometric correspondence between these structures and derives the electromagnetic resonant mode spectrum of the crista lumen modelled as a three-dimensional cavity. The central finding is that the fundamental mode along the lumen length falls at ~822 nm for a lumen of 300 nm—squarely within the absorption window of cytochrome c oxidase (CCO Peak 2, 810–850 nm), the terminal enzyme of the mitochondrial electron transport chain. This result resolves a prior negative finding that the gap dimension alone produces only extreme ultraviolet modes. Six testable predictions are presented, including tissue-type-dependent spectral fingerprints and metabolic-state-dependent frequency shifts. The rigour classification of each element of the correspondence is stated explicitly. The correspondence is established and testable; it is not claimed as proven.
