We apply the Displacement Framework to the immune system. S0_immune is the tolerant, surveilling, non-inflammatory configuration. Acute infection is correct bounded displacement with resolution via Tregs, IL-10, and specialized pro-resolving mediators. Chronic inflammation is return failure. Autoimmunity is wrong-attractor capture — tolerance lost. Allergic disease is a Th2/IgE wrong attractor.
Immunodeficiency is insufficient displacement capacity. Vaccination is attractor pre-shaping that reduces lifetime displacement burden. The immune-gut axis is formalized as external attractor-depth regulation via microbiome-derived SCFAs and Foxp3 Treg induction. Eight formal propositions are derived.
