A minimal route from pre-spacetime informational order to Lorentzian causality is developed from explicit structural principles. The starting point is a normalized positive operator on the complexification of a real Euclidean internal carrier. Its intrinsic reference basis separates population structure from an antisymmetric cohesion sector. Second-moment cohesion correlations define a symmetric order tensor whose cubic invariant selects an unoriented internal line and a residual sector within the minimal Landau theory. Balanced cohesion-carrier closure uniquely fixes the residual dimension to three and the full internal dimension to four. Continuous reversible binary distinctions on the residual direction sphere are minimally encoded by a complex two-component carrier. Minimal relational soldering, local integrability, residual isotropy, analyticity and nondegenerate unitary propagation then select a Weyl-type linear generator in the infrared regime. Its discriminant is a Lorentzian causal cone with one update-frequency label and three residual spectral labels. The construction separates structural inputs from deductions and isolates a homogeneous locally flat reference phase.
