This module defines the α-parameterized cost in logarithmic coordinates as G_α(t) = (1/α²)(cosh(α t) - 1). Researchers reducing the bilinear branch via higher-derivative calibration cite it to reach the one-parameter family. It imports the Cost module and supplies supporting definitions and lemmas to establish the log form for downstream fixation steps.

claim$G_α(t) = (1/α²)(cosh(α t) - 1)$ for α ≥ 1, where t is the logarithmic coordinate.

background

The module sits in the Foundation layer and imports the Cost module, which supplies the base J-cost J(x) = (x + x^{-1})/2 - 1. In log coordinates t = ln x this becomes the scaled hyperbolic expression. The setting prepares the α-family for coordinate fixation, with the downstream AlphaCoordinateFixation module quoting the form F_α(x) = (1/α²)(cosh(α ln x) - 1) to force the J function.

proof idea

This is a definition module, no proofs.

why it matters in Recognition Science

The module supplies the parameterized cost that AlphaCoordinateFixation relies on to show higher-derivative calibration forces J from the branch-selection theorem. It completes the reduction to the one-parameter family α ≥ 1 inside the Recognition Science forcing chain.
