ppnInverseStub
plain-language theorem explainer
This definition supplies a placeholder instance for post-Newtonian inverse approximation facts inside the Recognition Science relativity fixtures. Developers bridging RS constants to GR phenomenology would cite it while the full derivation remains open. The implementation reduces the required error bound to a trivial numerical check discharged by normalization.
Claim. The stub supplies an instance of the post-Newtonian inverse facts in which the approximation error satisfies $|error(pots, params, x, μ, ρ)| < 0.001$ for the relevant parameters.
background
The module supplies temporary instances for hypothesis classes that replace sorries while keeping the trust boundary explicit. Upstream constants include the fundamental tick duration τ₀ (duration of one recognition tick) and the lag coupling C_lag = φ^{-5} obtained from the self-similar fixed point. These enter the post-Newtonian parameterization through the eight-tick resonance and the Recognition Composition Law.
proof idea
The definition builds the instance by introducing the parameters pots, params, x, μ, ρ and applying simpa to reduce the goal to |0| < 0.001, which norm_num discharges directly.
why it matters
The stub closes a temporary gap so that PhenomenologyMatchingFacts and SphericalWeightFacts can be instantiated without sorries. It supports the chain from T5 (J-uniqueness) and T7 (eight-tick octave) toward observable corrections in weak-field gravity. The construction touches the open task of replacing the placeholder bound with a derivation from the phi-ladder mass formula.
