Relational Grounding and the Quantum Measurement Problem: Admissibility Conditions for Definite Outcomes

Relational Grounding and the Quantum Measurement Problem develops a constraint on outcome attribution within quantum mechanics. The paper distinguishes formal state assignment from located outcomes and introduces an admissibility condition: evaluation over candidate outcomes must range over actual members of reality rather than representations. From this, a Quantum Grounding Constraint is derived, showing that definite outcomes can only be attributed where relational grounding is established. The result does not solve the measurement problem but restricts its admissible form by excluding ungrounded outcome attribution. The framework applies this constraint across standard interpretations, clarifying the conditions under which definite outcomes can be meaningfully attributed.
