The Road Is Evidence: Scientific Cartography of Four Admissible Branches in General Coherence Field Theory

Theoretical programmes often prune alternatives before the alternatives have produced the evidence needed to distinguish them. This worked pre-measurement case preserves four materially distinct General Coherence Field Theory routes as isolated evidentiary lineages and reconciles them only through a read-only comparison node. A frozen common Standard Model interface contains 333 route-indexed operators. Symmetry-first reduction gives a rank-four structural signature, and exact symbolic quadratic response exposes route-local apertures, obstructions, Goldstone sectors, structural zeros, and kinetic mixing. A causally isolated parent-only counterfactual selects Route B under parsimony, erasing three of four structural feature classes and all six cross-route relations. Every possible one-route survivor erases at least two feature classes. Branch-dependence signatures D(Q) record minimal ancestral assumption sets and distinguish assumption robustness from branch dependence without assigning a probability of truth. Measurement execution remains pending.
