The Cost module supplies the explicit squared-ratio form of the J-cost function used throughout Recognition Science. Researchers deriving acoustic laws or variational principles cite it when mapping dimensionless ratios onto recognition cost. The module consists of a core definition together with elementary algebraic properties such as non-negativity and symmetry under inversion.

claim$J(x) = (x-1)^2 / (2x)$ for the recognition cost on a positive real ratio $x$.

background

Recognition Science derives all physics from the Recognition Composition Law. The Cost module supplies the concrete expression for the cost function J that satisfies this law with J(1) = 0. The squared-ratio form is algebraically identical to the hyperbolic expression J(x) = cosh(log x) - 1 that appears in the T5 J-uniqueness step of the forcing chain.

proof idea

This is a definition module, no proofs.

why it matters in Recognition Science

The module is imported by forty downstream modules that derive concrete physics from J-cost. It supplies the cost function for the Euler-Lagrange derivation in the Action layer, for the Sabine reverberation formula in room acoustics, and for pitch JND calculations in music. It directly implements the T5 J-uniqueness landmark by recording the explicit algebraic form.
