branch_selection
plain-language theorem explainer
The theorem asserts that if the RCL combiner with parameter c satisfies the coupling condition, then c must be nonzero. Researchers formalizing the Recognition Science composition law cite it to exclude the additive branch in favor of the bilinear representative. The proof is a direct one-line application of the forward direction of the RCL coupling equivalence.
Claim. If the combiner $P(u,v)=2u+2v+cuv$ is not separately additive, then $c≠0$.
background
The module formalizes branch selection under the strengthened composition consistency (L4*). A combiner is coupling when it is not separately additive, so that the interaction defect is nonzero for some pair of arguments. The RCL combiner is the polynomial $P(u,v)=2u+2v+cuv$ attached to the Recognition Composition Law family with free real parameter c. The upstream theorem RCLCombiner_isCoupling_iff states that this combiner is coupling if and only if c≠0.
proof idea
The proof is a one-line wrapper that applies the forward implication of RCLCombiner_isCoupling_iff to the supplied coupling hypothesis.
why it matters
This result forces the bilinear branch of the RCL family once the coupling requirement of the strengthened (L4*) is imposed. It is invoked by the contrapositive additive_branch_not_coupling and by the certificate branchSelectionCert. In the framework it completes the operator-level selection between the two branches of the RCL family, leaving only residual α-coordinate freedom for later calibration steps.
