The integration of ontology (O), normativity (N), and history (H) into a single coherent model faces a structural obstacle: no pairwise combination achieves non-reductive unification without systematic loss. This paper demonstrates, under a formal integration framework, that all binary models of V₃ = ⟨O, N, H⟩ fail the unification condition through reduction, elimination, or indetermination. The minimal integrating structure is derived as a profile of six necessary constraints (C1–C6), characterizing a bridge event: an H-localized occurrence of a non-interchangeable subject bearing determinate ontological status and non-derivative normative instantiation. Two evaluative modules—Historical-Ontological Density (DHO) and Multi-level Abductive Evaluation with Residue Penalty (MAER)—operationalize this profile for historical assessment. Applied to the event-cluster centered on Jesus of Nazareth, both modules yield convergent results: the candidate satisfies the DHO viability threshold, and its associated model achieves a MAER score dominating available alternatives. The result is a constrained abductive finding; no independent metaphysical or theological claim is established beyond what the structural and historical analysis warrants.
