C.26:12b - C.29 mathematical-lens use relation

C.26 is a C.29-compatible specialization for quantum-like modeling. It carries a pre-filled adequacy profile: preserved structure includes order, probe and contextual-probability effects when supported; lost structure includes physical quantum ontology; the canonical stop condition remains QL-NQ. A QL-lite note retains its lightweight use. Apply C.29:4.4’s reliance rule when more is needed: a conditional comparison or reusable explanation within the same assumptions may stay small; reliance as an adequate phenomenon model for prediction, a consequential decision, model adoption, benchmark/assurance input, Bridge-dependent use or transfer to further cases needs the full applicable account. Reuse the supplied C.26 profile and adequate existing validation rather than filling a blank FullCard.
