Blind Kernel Reduction Measure

Abstract

Positive weight detects blind residual pairs separated by a new definition.

Theorem 1.1 (Positive reduction weight detects a separated blind pair).

Proof. Machine-checked in Lean as D5/S3/ConceptDynamics/DefinitionEscape/BlindKernelReductionMeasure.blind_kernel_reduction_measure (✓ std3). ∎

Source. Repository-derived.

Commentary.

The imported blindResidual is used unchanged. For a proposed definition d, the measured reduction set is its intersection with the complement of the Setoid equality kernel of d. Thus the Lean definition is exactly the displayed P_Gamma formula and introduces no second residual or kernel.

The public hypotheses require the abstract real-valued set weight to be nonnegative and to vanish on the empty set. The conclusion packages the defining equality, nonnegativity, and the one-way implication from positive reduction weight to a blind residual pair separated by d. It does not assume that every nonempty set has positive weight.

Finite counting weight on Boolean state pairs supplies the positive example. A constant definition supplies the reverse example. A normalized Dirac-style weight supplies a nonempty separated set of weight zero, demonstrating why no converse is claimed.

The closing catalog, language-closure, and target-usefulness maxim is not asserted as a Lean proposition: the source supplies no formal catalog, closure, or usefulness predicates from which a faithful statement could be formed.
