-| Area | Artifact |
-|---|---|
-| Layering & dependency rule | the package layout and import rules |
-| Composition root | the `init.py` shape, idempotency, `get_svc` overloading |
-| Web edge | `OpenAPIFirstApp` bootstrap, handler-name = `operationId`, thin handlers |
-| CRUD slice | the four-file pattern (model / ports-db / ports-service / converters) |
-| Generic CRUD service | the base service adaptor |
-| Repository factory | base / populating / cached selection |
-| Worker | the poll loop, backoff, retry, status machine |
-| Progress bus | the bus port + in-memory adapter + streaming endpoint |
-| Human-in-the-loop | the durable pause + question document + resolve endpoint + resume map |
-| Infra adaptors | HTTP cache decorator, KV store port, LLM pool scaffold |
-| Testing | integration harness with fakes, fixture-parity pattern |
-| Docs | GSDFC + generated stubs + MCP bundle pipeline |
+These capabilities already exist as internal libraries. Reach them through the
+library registry MCP (`find_library(capability)`) and read the library's own MCP
+for its API. Writing a private copy of any of these is a defect.
