CE_8 Structural Underdetermination of Global Admissibility

This paper establishes that global admissibility cannot be uniquely determined from within any admissible representational regime. Even when all locally admissible structures are fixed, no further admissible principle exists that would select a unique global admissibility structure without violating standing. The argument is necessity-based and eliminative. It shows that attempts to infer global admissibility from consistency, completeness, symmetry, or maximality invariably introduce illicit scope expansion or hidden global anchoring. When such moves are excluded, multiple globally distinct admissibility structures remain equally compatible with all admissible local descriptions. The result explains why no admissible “view from nowhere” exists and why global foundations cannot be settled by internal reasoning alone. The paper introduces no selection rules or meta-criteria. It records a structural limit on admissible global determination that preserves the integrity of local constraint enforcement.
