Description This document establishes structural admissibility conditions for solid-state gas capture systems, including carbon capture, atmospheric water harvesting, and industrial gas purification. It defines invariant constraints under which capture functionality must arise from engineered geometric confinement within fully solid-state architectures, rather than from chemical affinity dominance, solvent mediation, or bulk phase transitions. The analysis is strictly non-constructive and does not disclose specific materials, frameworks, compositions, synthesis methods, or operating conditions. Instead, it formalizes identity-level structural requirements governing enablement, inventive step, and industrial applicability across gas capture domains. This document constitutes prior art at the level of structural admissibility.
