L2_5 Renormalization and Scheme Parameter Collapse

This paper establishes an impossibility result for renormalization- and scheme-based parameter freedom within a closed admissible framework. It proves that once admissibility is fixed by exhaustion and standing is conserved, differences attributed to renormalization choices or scheme selection do not correspond to admissible degrees of freedom. Any purported scheme dependence either collapses under admissible redescription into a fixed role or violates standing by introducing illicit parameters or covert scope transport. The analysis is strictly eliminative and non-constructive: it introduces no new primitives, specifies no procedures, and provides no operational guidance. The result functions as a boundary theorem, ruling out renormalization or scheme choice as sources of admissible freedom in closed systems.
