ψ⁸·Neutron Wind: Topological Retention Across the Frontier of Neutron Decay

This work extends the ψ⁸ theoretical framework to the extreme regime of neutron winds — transient, high-energy streams of free neutrons ejected from compact astrophysical sources such as neutron stars, supernova remnants, and binary mergers. The study introduces a post-metric architecture capable of retaining structural difference (Δψ) beyond the intrinsic decay limit of neutrons (τₙ ≈ 880 s), where conventional particle-based stability fails. Using retention nodes (Ξ), directional APEX alignment (ε·v̂), and intrinsic pseudo-time (τ), the ψ⁸·Neutron Wind model demonstrates that coherent topological structures can persist across the decay boundary, maintaining post-nucleonic continuity in one of the most unstable particle environments in the universe. The results have implications for compact-object astrophysics, high-energy plasma physics, and pre-nucleosynthetic cosmology.
