Unlike these frameworks, the waveband ontology is explicitly ontological and organizational: it formalizes how dominant interaction regimes structure behavior across disciplines, without introducing new dynamical equations or modifying existing laws. 127.7 Counterexamples and Regime Limitations To clarify the scope of applicability, it is necessary to identify regimes in which the waveband ontology provides limited or no descriptive advantage. These cases are not treated as failures, but as explicit boundaries consistent with the use of effective descriptions in physics. 127.7.1 Strongly Chaotic and Fully Turbulent Systems In systems characterized by fully developed turbulence or strong chaos across many coupled scales, no single dominant interaction band may persist over meaningful durations. In such regimes, rapid cross-scale energy transfer prevents stable coarse-graining, and waveband classification becomes non-informative. 127.7.2 Near-Singular and Extreme Regimes Near singularities, critical points, or extreme relativistic or quantum-gravitational regimes, characteristic scales may collapse or diverge. In these cases, the identification of bounded interaction bands may fail, and the ontology defers entirely to fundamental theories appropriate to those regimes. 127.7.3 Microscopic Few-Body Systems In systems with very small numbers of degrees of freedom, statistical or coarse-grained descriptors lose relevance. When behavior is dominated by discrete events rather than persistent regimes, waveband descriptions may add no meaningful structure beyond direct dynamical analysis. 127.7.4 Rapidly Switching Boundary Systems Systems operating persistently at regime boundaries may switch dominant interaction bands under minimal perturbations. For such systems, waveband classification must be contextdependent and time-resolved; fixed role assignments are inappropriate. 127.7.5 Interpretive Limit Finally, the waveband ontology does not generate quantitative predictions independently. Where precise numerical results are required, it must be supplemented by established theoretical or computational methods. Summary of Limits. The waveband ontology is most effective where persistent structure, dominant interactions, and stable scale separation exist. Its applicability diminishes where these conditions fail. 272
