Dimensional Saturation Threshold

The Dimensional Saturation Threshold is the point in the book's harmonic-ladder account beyond which recursive discharges no longer open new degrees of freedom but reinforce the dimensional lattice that already exists, reached at the three spatial axes plus one temporal axis observed at our depth. Chapter 4 sets it at the fourth overtone of the cosmic string, the fourth Nova, the Saturation Nova, where recursion coheres into the 4D Lattice of Reality. Past the threshold, higher harmonics manifest as recursive echoes that scaffold form from atomic orbitals to galactic spirals without adding dimensions, and energy overflow produces Harmonic Novas that strengthen the existing axes. The Recursive Growth Law places no cap on dimensional capacity: D(n) = n grows by one axis per completed pulse. The threshold therefore records where our universe's dimensionality is observed to stand, not a maximum derived from the law; a binding rule on dimensional capacity is an open question. At our depth the saturation is the prime limit of the harmonics held in tune, 2, 3, 5 and 7 (Prime Harmonic Dimensions), and our sky's dark matter measures it: four (Dimension Count from the Dark Sector). It connects to Dimensional Saturation, Harmonic Novas, Spacetime Genesis, UniSpheral Dimensional Count Law, UniSphereal Dimensional Capacity and Protected Dimensionality, Prime Harmonic Dimensions and Etheric Harmonics.
