L3_2 Overdetermination Proofs

This paper provides overdetermination results for the admissible interior of a closed epistemic system. It proves that admissible elements are fixed by multiple, independently binding constraints, such that no single constraint or small subset carries determining authority. This overdetermination eliminates compensatory adjustment, trade-offs, or selective relaxation without collapse. The analysis is strictly eliminative and non-constructive: it introduces no new primitives, specifies no procedures, and provides no operational content. The result functions as a boundary theorem, establishing that admissibility is multiply locked and not recoverable through localized modification once closure by exhaustion is achieved.
