Unused primitive methods

assertNoUnusedPrimitiveMethods requires every method exposed by a primitive insertion to have at least one call site in the project. An unused method is dead interface and should be removed from the primitive.

export function removeUnusedPrimitiveMethods(graph: ArchitectureGraph) {
  assertNoUnusedPrimitiveMethods(graph.graph);
}

The check is graph-wide, so it can find a method declared in one module that is never called by any component, service or feature module. This also applies to CraftTS libraries included in the analyzed project: public methods must be kept intentionally, or the project should exclude that library from the graph.

The error includes the primitive, method and declaration location:

Primitive method state:counter.decrement is never used in this project (counter.ts:12). Remove it.

Methods bound internally with on$ are not exposed and are not checked.
