Abstract
ABSTRACT : This paper synthesizes three completed studies that applied the same preregistered structural-remainder test to three independently developed modeling traditions. System Dynamics returned sixty of sixty constructs without residual; Network Theory returned thirty-five of thirty-five; and UML returned a closed candidate set of one hundred forty-two metaclasses, with no exclusions and no residual among the two hundred seventy-one novel structural contributions those metaclasses make. Across 237 constructs, none required a fifth Pattern, ninth elemental role, fifth dynamic, or other irreducible organizational structure outside DSRP-484. The three run papers contain the construct-level evidence; this synthesis tests what can be inferred from their convergence. Two findings become visible only when the runs are read together. The first is forward-facing: three fields with no shared vocabulary—stocks and flows, nodes and edges, metaclasses and associations—resolve to the same four Patterns and eight elemental roles. The constructs that resisted decomposition most strongly did so for the same reason: each was a constraint placed on a Pattern rather than a new Pattern. The second finding is backward-facing and addresses the possibility that a flexible calculus can redescribe anything after the fact. When a formalism omits an elemental role from its native grammar, the missing organizational work reappears in auxiliary constructs, attributes, rules, or procedures. System Dynamics supplies one emblem: the cloud. Network Theory supplies six load-bearing cases. UML supplies roughly seven hundred countable representational expenditures, including eighty-three derived properties, eleven hand-built negations, four surrogate metaclasses for a Link the metamodel does not contain, and four hundred forty-nine constraint rules. These features were not necessarily designed to repair DSRP-defined omissions and may also serve computational, syntactic, or implementation purposes. The narrower claim is structural: they perform organizational work the native grammar does not perform directly. Together, the findings support more than retrospective containment: omissions in a formalism’s native grammar predict the location and function of its later representational expenditures. The paper derives six prospective predictions and specifies their failure conditions through four connected tests—I/O, composition, ablation, and patch—applicable to any formalism.
