Quantum Reference Algebra for Information Flow

A positive control cost does not become a Lorentzian metric simply by being renamed. These three papers connect operator representation, actual propagation and physical actuation. The connection is conditional on the carrier and interaction: a per-species cone is not automatically a common cone, and a representation image is not the whole apparatus that realizes it. A develops propagation and readout, B realizes protection and corrective control, and C follows representations into local contacts, material sources and finite autonomous execution. The separate Mass–Energy, Null Cluster and No View papers extend these questions; they remain companion papers rather than additional chapters in this volume.
