The Gruranium Diagnostic of Spurious Necessity

Is physical necessity a feature of the world or a byproduct of our conceptual machinery? This paper argues the latter, deploying a Gödel-inspired isomorphism to diagnose lawlikeness as a truth-categorical error. Harnessing a cumulative proof-sequence—Grue, Gruranium and Uranium—the argument reveals the successive progression of artifactualization, wherein definitive (DF) semantic entailment displaces descriptive (DS) empirical constraint. The diagnostic centers on a scheduled truth-categorical rupture, illustrating precisely when and how lawlikeness crystallizes from definitive indexing instead of descriptive regularity. By exposing spurious necessity as a symptom of logical closure rather than any empirical barrier, this diagnostic untangles the "New Riddle of Induction" and the asymmetry of explanation, dispelling contingent necessity and restoring the necessary contingency that scientific discovery demands. Predication must not be routinely confused with prediction.
