B6 Admissibility Semantics Are Impossible

This paper establishes an impossibility result for semantic grounding of admissibility within a closed epistemic framework. It proves that admissibility cannot be defined, stabilized, or recovered through semantic interpretation, meaning assignment, or representational intent without violating standing conservation. Any attempt to treat admissibility as a semantic property is shown to introduce external reference dependence, deferred justification, or illicit scope transport, collapsing admissibility. The analysis is strictly eliminative and non-constructive: it introduces no new primitives, specifies no procedures, and provides no interpretive or operational semantics. The result functions as a boundary theorem, ruling out semantic accounts of admissibility in closed systems.
