Information Transfer Across Universe-Rings: The Siphon Mechanism as a Resolution to the Hawking Information Paradox in the Concentric Orbital Cosmological Model

Paper 3 and companion to Vázquez González (2026a) DOI: 10.5281/zenodo.19950582 and Vázquez González (2026b) DOI: 10.5281/zenodo.19991607. We propose the siphon mechanism as a resolution to the Hawking information paradox within the Concentric Orbital Cosmological Model (COCM). Black holes at the boundary between adjacent universe-rings are coupled to two distinct environments by the inter-ring dark energy gradient. The total Hilbert space is enlarged to restore unitarity without modifying local physics. Three simultaneous transfer modes are identified: Water (coherent), Foam (partially coherent), and Vapor (thermal). Five falsifiable predictions are derived, testable by ATHENA and ngEHT.
