This stage uses the cell-centred path scaling A_n=n²L_n, density-normalized channels, and an exactly one-way subsystem response inside a symmetric continuous-time Markov generator. It asks which statements survive refinement, which disappear under another limit, and which are artifacts of the preparation or measurement protocol.
