Reverse Infiltration: Quarantine, Consciousness Verification, and the Berserker Hypothesis

The article "Reverse Infiltration: Quarantine, Consciousness Verification, and the Berserker Hypothesis" addresses the protection against threats that could enter our Universe during interuniversal transitions. The author views reverse infiltration as an inevitable risk of any contact with an alien reality. Unlike existing works, the article contains a typology of threats, historical analogies, and detailed protection protocols. The first part introduces a typology of threats: informational, material, field-based, cognitive, and ontological. For each, mechanisms of action and protection strategies are described. Historical precedents (the Columbian Exchange, species introduction to Australia, contact with indigenous peoples) show that contact between isolated systems almost always leads to catastrophe for one side. These lessons are extrapolated to the multiverse. Quarantine protocols include four levels: the breakthrough zone, the observation zone, the biological/informational verification zone, and the cognitive verification zone (consciousness check). The "Doubt" protocol is a multi-stage reality verification through epistemic, psychological, informational, and ontological channels. The berserker hypothesis (automated killer probes) and its connection to pre-atomic civilizations are examined. Protocols for protection against informational infiltration are proposed, including carrier isolation and memetic virus checking. The scientific justification is based on updated SETI protocols (IAA, 2026), COSPAR policy (2024/2025), false memory research (Andrews & Brewin, 2024), and works on environmental history (Crosby, McNeill, Diamond). The author emphasizes that quarantine is a duty to humanity, consciousness verification is a guarantee of preserving identity, and protection against berserkers is a matter of survival.
