Field Topology Theory (FTT) proposes that particles, forces, and quantum numbers emerge as topological configurations of a single continuous spacetime field. This paper specifies nine requirements that any candidate FTT field equation must satisfy simultaneously: (0) stable topological defects only in 3+1 signature; (1) reduction to general relativity far from defects; (2) stable ℤ₂ winding defects giving fermion statistics via the Finkelstein-Rubinstein theorem; (3) well-defined behaviour through metric signature transitions at det(g) = 0; (4) Euclidean phase solutions corresponding to dark matter; (5) a minimum action scale ℏ from vacuum topology; (6) discrete mass families matching Koide ratios via binary tetrahedral symmetry; (7) fractional topological twist stable only in confined bound states; (8) topological path dependence in defect nucleation producing the baryon asymmetry. Each requirement is mapped to existing mathematical structures, the precise gap preventing its realisation is identified, and falsification conditions are stated. Five claims were subjected to adversarial review and revised; the revisions are documented. A constructive literature survey confirms that individual mechanisms satisfying each requirement exist — spanning Skyrme models, scalar-tensor theories, topological soliton physics, and braid pre-geometries — but no single equation currently combines them. The specification is offered as a roadmap for construction of the complete field equation. Working draft.
