Scope & limitations

OpenAPI 3.x JSON only; no YAML, external $ref fetching, full schema validation, authentication flows or request execution. Reference cycles and unresolved local references are errors. Request-body schemas are not expanded in this operation index. JSON numbers use JavaScript binary64 precision; keep large exact identifiers as strings. Numeric overflow is rejected.
