Ontic Availability as Constraint Governed Fixation

This paper shows that ontic availability is not a primitive feature of reality, but a fixed outcome of constraint-governed admissibility. What appears as the presence, absence, or persistence of entities is shown to arise from stable fixation under a complete bundle of standing-preserving constraints, not from independent existence claims or metaphysical commitments. The analysis is strictly structural and eliminative: it introduces no new ontologies, mechanisms, or explanatory layers. By recasting existence as constraint-governed fixation rather than as an open-ended metaphysical category, the paper closes a major source of ontological ambiguity across physics and mathematics and places the limits of legitimate existence claims on record.
