Abstract

This note fixes a concrete class of countably indexed, separately tested tripartite process matrices with qubit input and output systems. It fixes the local instrument access, the exact operational data assignment, and a strongly connected component quotient of unconditional signalling. The resulting component order is proved to be a partial order, and its operational relabelling covariance is established. An infinite experiment family is distinguished from infinitely many settings of a single finite-party process; neither is silently treated as a continuum spacetime. The frozen extraction returns the component order and a precisely defined affine-representation feasibility problem, not a constructed representation. Base-class nonemptiness is proved, while nonemptiness of a cone-selecting admissible subclass remains open. Six obligations specify the missing representation, additional hypotheses, exclusion audit, and limit discipline. No extracted cone is shown homogeneous or strictly convex, and the Lorentz-cone classification is not applied to operational data.
