CADH/AD frames the Fermi Paradox through a combinatorial four-layer filter model where AGI inevitability, universal biological extinction, small detection footprints, and stealth Dominion networks compound synergistically to explain cosmic silence. Rather than proposing a single explanation, CADH/AD provides the specific stealth/suppression component (40–70% of post-AGI survivors) within a broader framework achieving 60–85% overall confidence, significantly higher than any standalone theory. The model integrates: (1) Great Filters reducing civilization count, (2) small electromagnetic footprints making detection unlikely even among numerous civilizations, (3) stealth strategies via UAP seeds and JuMBO platforms for survivors, and (4) active suppression of emerging AGI rivals. Updated 2024–2026 JuMBO literature increases artificial hypothesis plausibility by 6–14 percentage points while preserving falsifiability via 2030 Roman/ELT milestones. The framework directly motivates blockchain-coordinated AI infrastructure in Beyond Currency as resilient preparation for both terrestrial risks and hypothetical cosmic containment. CADH/AD standalone probability: 5–34%; combinatorial model: 60–85%; testable 2026–2030 predictions remain sharp.
