On the Structural Instability of Nullity

This manuscript develops a structural framework for admissible description without assuming any primitive ontology, spacetime, causality, dynamics, or mathematical substrate. Beginning from the requirement that admissible re‑description must preserve equivalence under refinement, the work demonstrates that absolute nullity cannot sustain admissible closure. The resulting exclusions force a hierarchy of structural conditions: finite diagnostic burden, quotient compression, regeneration stability, and induced relational grammar. Ordering, geometry, and effective physical structure appear only as consequences of these admissibility constraints, not as primitives. The analysis is eliminative, jurisdictional, and prior to physics, logic, and cosmology
