clag_locked
plain-language theorem explainer
The declaration defines the locked lag coupling constant as phi to the power of negative five. Researchers testing the ILG rotation curve model on the SPARC sample with zero free parameters cite it to enforce the global-only policy. The definition is realized as a direct noncomputable alias to the canonical constant supplied by the Constants module.
Claim. The locked lag coupling constant is defined by $C_ {lag} = phi^{-5} approx 0.090$.
background
The SPARC Chi-Squared Falsifier module encodes the test for the ILG model under the Recognition Science parameter lock. Three constants are fixed from phi: alpha_t = (1 - 1/phi)/2, C_lag = phi^{-5}, and Upsilon_star = phi. The upstream cLagLock supplies the canonical value, documented as the locked C_lag constant C_lock = phi^{-5}.
proof idea
One-line definition that aliases the upstream cLagLock constant from the Constants module.
why it matters
This definition supplies the C_lag value required by the GlobalOnlyPolicy structure and the parameters_from_phi theorem inside the SPARCFalsifierCert. It anchors the zero-free-parameter falsification protocol to the phi-ladder of Recognition Science. The module uses the locked value to compute median chi2/dof across the SPARC sample without per-galaxy fitting.
