This paper explains how real three-axis (triadic) rotation can remain stable in Holosphere Theory. In ordinary rigid-body physics, multi-axis rotation is unstable and tends to tumble. Here the stabilizing mechanism is coherence phase-locking in a coupled lattice of hadronic-scale Holospheres. Small misalignments are corrected elastically by a restoring response that redistributes strain through neighboring sites. When misalignment exceeds a critical cutoff angle, the lattice switches regimes and activates vacancy defects that export strain as quantized packets along admissible corridors, preventing runaway instability. The paper defines the threshold rule, derives an effective coherence length that sets stability shells, describes how perturbations heal or reroute through defect transport, and outlines a discrete simulation and laboratory proxy program to test the stabilization mechanism. The result is an operational foundation for triadic spin as a dynamically stabilizable degree of freedom in a memory-bearing coherence lattice.
