Quantum Mechanics as CG Closed Redescription Bookkeeping

This paper characterizes quantum mechanics as a closed redescription regime governed by constraint-generated admissibility, rather than as an ontic theory of physical entities or processes. The analysis is eliminative: it shows that once standing preservation, admissibility, and redescription stability are enforced, quantum mechanical structure emerges as a bookkeeping system that exhausts all admissible local redescriptions without leaving residual degrees of freedom. Quantum states, operators, and measurement constructs are treated as representational artifacts licensed by closure, not as primitive elements of reality. The paper demonstrates that attempts to extend, reinterpret, or operationalize quantum mechanics beyond this closed redescription role introduce illicit scope transport, deferred admissibility, or duplication of enforcement, all of which violate standing conservation. No primitives, mechanisms, algorithms, or procedural sequences are introduced. The contribution is boundary-setting: it clarifies why quantum mechanics must be understood as a CG-closed redescription framework, and why treating it as incomplete, extendable, or ontically explanatory is structurally inadmissible rather than an open interpretive choice.
