DESCRIPTION: This document establishes a formal admissibility framework for Superluminal Localization Theory (SLT). It defines which classes of theoretical routes, interpretations, and implementation attempts are structurally compatible with SLT, and which are non-realizable by definition. It is intentionally non-enabling and provides constraints, boundary conditions, and invalid falsification conditions without disclosing mathematics, algorithms, parameters, thresholds, experimental designs, or engineering procedures. It includes a clarification that SLT is falsifiable in principle while remaining non-operational in disclosure. NOTES: Non-enabling companion prior-art disclosure defining admissibility constraints and non-realizable routes. No equations, parameter values, algorithms, simulation methods, experimental setups, or engineering architectures are provided. Any implementation, derivative system, or commercial exploitation of SLT or SLT-compatible frameworks requires explicit authorization by the author.
