Part 39: KIBBLE–ZUREK DYNAMICS IN PHASON PHASE TRANSITIONS OF DUAL–H4 GEOMETRY Causal Freeze-Out, Topological Defect Formation, Primitive Mass Precursors, and Early Geometric Structure

Overview Parts 37 and 38 developed the transition-and-renewal branch of Origin Geometry, in which geometric saturation may lead to phason-mediated projection restructuring and renewed geometric accessibility 5, 6. In that branch, geometric expansion may eventually enter a saturation regime, accumulated frustration may activate phason degrees of freedom, and the effective projection window may undergo a large-scale transition: W → W' Part 38 then argued that the new projection window W' may reopen geometric accessibility, allowing renewed topological growth and the birth of a new effective H₄-like realization. The present Part investigates the next dynamical problem: can the newly emerging H'₄ realization establish global coherence instantaneously? Kibble-Zurek Dynamics and Phason Ordering If information, stress, and phason alignment propagate at finite speed, the answer is generally no. Different regions of the newborn network may select locally distinct phason configurations before global synchronization is possible. This places the early post-renewal regime in the conceptual domain of Kibble–Zurek-type dynamics 10–13. We model the phason-ordering transition using an effective control parameter ε (t), quench time τQ, relaxation time τ (ε), and correlation length ξ (ε). Near the transition: ξ (ε) ~ ξ₀ |ε|^ (−ν) τ (ε) ~ τ₀ |ε|^ (−zν) For a linear quench, the freeze-out time (tₕat) and freeze-out length (ξₕat) scale as: tₕat ~ τ₀ (τQ / τ₀) ^ (zν / (1 + zν) ) ξₕat ~ ξ₀ (τQ / τ₀) ^ (ν / (1 + zν) ) The resulting domain structure produces a finite defect population, whose scaling is controlled by the freeze-out length 10–15: nD^ (d) ~ (ξₕat) ^ (−d) where d denotes the effective dimension in which defect density is measured. These defects are interpreted not as Standard Model particles, but as primitive geometric structures: localized failures of phason coherence carrying stress, pinning energy, and topological information. Downstream Consequences and Scope The framework then explores four downstream consequences: primitive mass localization, projection-sector chirality imbalance, hidden defect populations as dark-sector precursors, and primordial geometric perturbations. Each is treated as a possible geometric precursor rather than as a completed derivation of particle physics, baryogenesis, dark matter, or inflationary perturbations 7–9, 34–38. The central claim of Part 39 is therefore limited but important: non-adiabatic phason ordering during geometric renewal naturally provides a mechanism for causal freeze-out, topological defect formation, and primitive geometric structure generation in Cyclic Origin Geometry.
