A truth-evaluable comparison operator on positive reals satisfies the laws of logic. Workers on the Logic Functional Equation paper cite this to close the Reality implies Logic direction. The proof is a term-mode application of operative_to_laws_of_logic using the operative property and finite pairwise closure extracted from truth-evaluability.

claimLet $C: (0,∞) × (0,∞) → ℝ$ be a comparison operator. If $C$ is truth-evaluable (self-comparisons evaluate to zero, reorderings are single-valued, the map is continuous on positive pairs, and composites admit finite pairwise polynomial closure, plus scale invariance and non-triviality), then $C$ satisfies the laws of logic: identity, non-contradiction, excluded middle, scale invariance, and route independence.

background

This module encodes the Reality to Logic implication for the Logic Functional Equation paper. A ComparisonOperator is a function assigning a real cost to pairs of positive reals. TruthEvaluableComparison is the minimal structure whose fields are self-evaluations to zero, single-valued reorderings, continuity on the positive quadrant, and finite pairwise polynomial closure for composites, together with scale invariance and non-triviality.

proof idea

The proof is a direct term application of operative_to_laws_of_logic. It supplies the operative positive-ratio comparison obtained from truth_eval_to_operative C hT and the finite pairwise closure given by truth_eval_implies_composition C hT.

why it matters in Recognition Science

This theorem completes the Reality implies Logic leg of the Logic Functional Equation paper by translating truth-evaluability into the SatisfiesLawsOfLogic structure. It supports the forcing chain toward the Recognition Composition Law. The result is fully proved with no open scaffolding.
