The module establishes that the J-cost function is non-negative and compatible with measure theory constructions in Recognition Science. It would be cited by researchers formalizing probabilistic or integral-based models atop the RS functional equation. The module imports Mathlib and the Cost module to introduce definitions for canonical measures and measurability certificates, with no complex proofs required.

claimThe J-cost function $J$ satisfies $J(x) = (x + x^{-1})/2 - 1$ for $x > 0$, is non-negative, and induces a canonical measure on the positive reals that is compatible with the Recognition Composition Law.

background

This module sits in the mathematics layer of Recognition Science and imports Mathlib for standard measure theory alongside IndisputableMonolith.Cost, which supplies the definition of J-cost. It introduces CanonicalMeasure as the measure derived directly from J-cost values, jcost_measurable to certify that J-cost is a measurable function, and MeasureTheoryCert as a formal certificate of compatibility. The local setting assumes the non-negativity of J-cost and builds on the upstream Cost module to enable integration and counting arguments within the phi-ladder framework.

proof idea

This is a definition module, no proofs. It defines CanonicalMeasure, canonicalMeasureCount, jcost_measurable, MeasureTheoryCert, and measureTheoryCert to record the non-negativity and measurability of J-cost in a form usable by Mathlib's measure theory library.

why it matters in Recognition Science

This module supplies the measure-theoretic foundation that supports higher constructions in the Recognition Science framework, including those involving the eight-tick octave and mass formulas on the phi-ladder. It ensures J-cost can participate in integral statements that connect to the forcing chain from T5 onward.
