Realitas Clausa Per Exhaustionem

This paper formally asserts and justifies the closure of reality under admissibility by exhaustion. It establishes that, once nondegeneracy and standing conservation are enforced, no admissible extensions, refinements, or alternative ontologies remain available without violating standing and failing closed. The argument is eliminative rather than constructive: all remaining candidate structures are shown to collapse into equivalence or inadmissibility. No dynamical origin stories, probabilistic assumptions, or operational criteria are introduced. The result places on record the claim that “reality,” insofar as it is admissibly describable, is closed by necessity rather than contingent completion, and that further foundational degrees of freedom are illusory.
