Validation of Structural Flux Dynamics in Interstellar Object 3I/ATLAS (SPT v1.3 — Part VII)

This work presents Part VII of the SPT v1.3 release, focusing on the validation framework for applying the Structural Flux Paradigm to interstellar object 3I/ATLAS. Incorporating observational constraints from December 2025 and the laminar-coupling baseline established in earlier parts, this study outlines the structural, thermodynamic, and dynamical expectations for substrate–object interactions during the Jovian approach. Particular emphasis is given to the statistical separation between radiative geometry, thermal coupling efficiency, and residual dissipation channels. The validation protocol presented here consolidates the predictive aspects of SPT v1.3, preparing the ground for the application model in Part VIII.
