E.4.PFR:1 - Problem frame

Pattern frameworks need several relation functions. One pattern may specialize another. A local framework edition may depend on a domain-framework edition or selected Core content in an FPF edition. A publication occurrence may expose a selected set through a carrier. A skill pack or MCP-backed service may provide access to that set. A generated graph may suggest candidates. A quality result may evaluate a pattern version. Those claims differ in subject, predicate, identity, use, evidence, and change behavior.
