MarkedIf
Type, in @jr2/orchestrator/src/http-effect.ts. It is type plumbing: it computes a type from the types of a Machine or of its parts, and a workflow module does not write it. The signature of an export, or a type that it names, names this type, so its declaration is here. The Authoring surface page lists each export.

type MarkedIf<V, T> = [Extract<V, OpenSecretMark>] extends [never] ? T : T & OpenSecretMark;
