The four opportunities affect different objects and failures—pattern geometry, physical probe motion, specimen provenance, and concentration measurement—and use independently adoptable domain interventions with distinct causal paths. All six pairs therefore satisfy the requirement to differ in problem, intervention, and causal path."}
