Relationship to independent tuner enforcement

This is a manufacturer / OEM matter. It is not part of the individual-tuner criminal docket set and no pardon of an individual tuner defendant affects it. Cross-linkage exists only through shared statutory authority (Clean Air Act §§ 203, 205, 213) and the underlying defeat-device theory.
