note: Apollo's OpenAPI declares zero components.schemas — every request and response body is inlined —
  so the entity graph is derived from path segments and the id-reference fields carried in request bodies
  and path parameters rather than from $ref links. Apollo IDs are unprefixed 24-character MongoDB ObjectId
  hex strings (e.g. 60c39ed82bd02f01154c470a); there is no per-type id prefix to key on.
