Certificate module for the RS astrophysics structural claim labeled 009. It defines a nonnegative domain cost, a positive canonical threshold, and packages both into an inhabited certificate record. Auditors of the AST structural chain cite it as the local claim bundle. Content is mostly definitions plus elementary nonnegativity and equality lemmas over the RS cost layer.

claimIntroduce a domain cost $C$ with $C \ge 0$ and a pointwise equality identity, a canonical threshold $T > 0$, and an inhabited certificate packaging $(C,T)$ for structural claim RS-AST-009.

background

Recognition Science measures mismatch with the J-cost from the Cost layer: $J(x) = (x + x^{-1})/2 - 1$ (equivalently $\cosh(\log x) - 1$), forced unique by the T5 step of the unified forcing chain. Constants supplies the RS-native tick $\tau_0 = 1$.

This module sits in the Astrophysics domain and isolates one structural claim (index 009). Sibling declarations name a domain cost, its nonnegativity and an equality-at-evaluation lemma, a canonical threshold with positivity, and a certificate type RSASTStructural009Cert with an inhabited instance. The pattern is a self-contained claim bundle rather than a deep derivation from the mass ladder or eight-tick kinematics.

No external astrophysical data enter here; the objects are pure RS-cost constructs meant to be wired into larger structural theorems later.

proof idea

Definition-and-certificate module, not a deep proof script. Domain cost and canonical threshold are introduced as defs; nonnegativity and positivity are short lemmas over the imported Cost/Constants facts; the equality-at-point lemma is an algebraic identity for the cost evaluator. The certificate record is assembled and shown inhabited by supplying those fields. No multi-step tactic argument beyond elementary positivity and rewriting.

why it matters in Recognition Science

Gives the local certificate surface for structural astrophysics claim 009 inside the RS monolith. Downstream used-by edges are empty in the current graph, so this module is a leaf bundle: it freezes the cost/threshold interface that a parent AST structural theorem would import when closing the 009 slot. It does not itself touch T5–T8, the RCL, or the $\phi$-ladder mass formula; it only standardizes the cost-threshold pair those layers would consume for this claim index.
