This paper identifies the minimal non-local consistency predicate sufficient to generate four-dimensional Lorentzian spacetime from featureless abstract distinctions, continuing the axiomatic framework U=(D,E,C) established in Paper I (DOI: 10.5281/zenodo.18938529).Five experimental phases are reported. A grid search over 144 local predicate configurations confirms the dimensional ceiling at d=2.51 without exception, extending the Locality-Dimension Theorem of Paper I. Free-evolution attractor experiments show that local predicates converge to d=1.64, not d=4. A hierarchy of four non-local feedback predicates (NL1 through NL4) approaches but does not reach d=4, revealing that sequential layered growth architecture is the fundamental bottleneck. A systematic study of five relational predicate classes (R1 through R5) discovers a clean empirical law: d = 0.614k + 0.552 (R2=0.978), where k is the dimension of the abstract ordering space. A mixed k=5/k=6 predicate with parameters alpha*=0.864 and tf*=0.328 achieves d=3.92 plus or minus 0.21 across 12 independent runs, with the d=4 line inside the confidence interval.The central result is that four-dimensional spacetime is the natural geometry of an abstract 5.86-dimensional Lorentzian ordering relation on featureless distinctions. No physical coordinates, no Minkowski space, and no physics are assumed at any step.
