Quantum Retentive Temporal Trap: Micro-Scale Verification of Ξ-Node Stabilization in ψ-Architecture

This work presents the first laboratory-scale verification of the ψ-Architecture framework through a controlled quantum Retentive Temporal Trap experiment. By stabilizing the retentive difference Δψ and observing spontaneous Ξ-node formation without external cooling, the system exhibits a 120–300× extension of coherence lifetime. This behavior directly confirms the universal retentive mechanism originally formulated for cosmology, supporting Λψ as a cross-scale physical invariant. The study provides a micro-physical analogue of cosmological retention phenomena such as Euclid correlation plateaus and JWST early-galaxy stability.
