specifyCatalog

Override to declare which of this element's inputs and outputs are most important, so applications can surface them first. Entirely optional and purely declarative — nominate the controls, random-variable parameters, responses, and counters this element exposes, preferably by passing the instances it already holds. Called during catalog assembly (when Model.modelCatalog or ksl.simulation.Model.modelDescriptor is read), after the element graph is complete, so it must be side-effect-free.

Nominations from every element roll up through the hierarchy into the model's catalog. Because a catalog is meant to be a small, curated set, nominate where you have the context to judge salience — typically the top-level element representing the system — rather than having every fine-grained, heavily-reused element nominate itself. A model assembler can prune or override the result via Model.curateCatalog.
