ψ-Coherence Profile: Retentive Shells at the Edge of the Cosmic Web

The article introduces the ψ-Coherence Profile as a formal retentive metric for identifying structurally stable void shells in Euclid DR1 weak-lensing maps. These high-coherence boundaries exhibit suppressed transverse drift and persistent density gradients that standard ΛCDM or N-body simulations cannot fully reproduce. Within the ψ-Architecture framework, this stability is modeled through the Λψ equilibrium term, the vanishing gradient Δψ → 0, and the persistence of retentive nodes Ξ. The paper defines the ψ-Coherence Profile as a measurable topological quantity that distinguishes dissipative evolution from structural retention, positioning void shells as observational witnesses of the universe’s transition into the post-dynamic regime.
