WHY FREE MAJORANA FERMIONS ARE STRUCTURALLY NON-REALIZABLE UNDER ENFORCED PHYSICAL CONSTRAINTS

This paper examines whether a free-propagating Majorana fermion is physically realizable under a strict enforcement-only ontology. Physical admissibility is defined exclusively by the presence of enforcing mechanisms: force, energy exchange, momentum exchange, reciprocal back-reaction, or modification of physical evolution through interaction. The Majorana condition is analyzed as a self-conjugacy identity imposed on internal degrees of freedom and is tested using eliminative logic: the condition is removed while holding mass, couplings, interaction fields, and energy–momentum content fixed. The analysis demonstrates that no enforcing mechanism is introduced by the condition itself and that physical evolution, including inertial and gravitational back-reaction, remains invariant in free propagation. The result follows by logical necessity: in the absence of an enforcing mechanism, the free Majorana fermion is structurally non-realizable under the defined physical constraints. Bound states, collective modes, detector inference, and mathematical consistency are explicitly excluded from the scope.
