Physics certificate module that packages a nonnegative domain cost functional together with a strictly positive canonical threshold. Researchers citing structural RS physics claims use it as a named certificate object rather than as a deep theorem. The module is mostly definitions plus elementary positivity and evaluation lemmas, closed by an inhabited certificate record.

claimA domain cost $C$ is a real-valued cost on the RS domain, nonnegative at every admissible point, with a fixed evaluation identity at the distinguished argument. A canonical threshold $\tau_\ast>0$ is fixed. The module supplies an inhabited certificate record asserting these structural facts together.

background

Recognition Science measures mismatch with a J-cost (the unique cost forced by the Recognition Composition Law, $J(x)=(x+x^{-1})/2-1$). The imported Cost layer supplies that functional and its elementary calculus; Constants supplies the RS-native tick $\tau_0=1$.

This module sits in the Physics structural certificate series. It does not re-derive $J$; it introduces a domain-level cost wrapper and a positive canonical threshold used as a comparison scale for structural inequalities. Sibling names indicate evaluation-at-a-point, nonnegativity, and threshold positivity as the local API.

The theoretical setting is bookkeeping for later physics claims that need a named, nonnegative cost and a fixed positive cutoff, not a new dynamical law.

proof idea

Definition-and-certificate module, not a deep proof development. Domain cost is introduced as a definition; evaluation and nonnegativity are short lemmas (likely unfolding or direct Cost facts). Canonical threshold is a positive constant definition with a one-line positivity proof. The certificate record bundles these facts; inhabitation is by constructing the record from the lemmas already proved.

why it matters in Recognition Science

Gives the Physics layer a reusable structural certificate (domain cost nonnegative, canonical threshold positive) so downstream RS physics statements can cite one named object instead of re-proving cost bookkeeping. No downstream edges are recorded in the graph yet, so this module is presently a leaf certificate rather than a parent of named theorems. It touches the Cost and Constants infrastructure that underwrite J-cost arguments and RS-native units, but it does not itself advance the T0–T8 forcing chain, the mass ladder, or the alpha band.
