        Universal response envelope. Successful responses include the business
        payload as additional top-level fields alongside `correlationId` and
        `meta`. Failed responses (auth errors, validation errors) only populate
        `correlationId` and `meta`, with `meta.errorCode` and `meta.error`
        describing the failure.

        Application-level metadata for every API response. Inspect `status` and

        as HTTP 200 with `meta.status: 400`).

          description: >-
            Application-level status code. For successful operations this
            mirrors the HTTP status (e.g. 200). For validation failures it
            reports the logical status (e.g. 400) even though the wire HTTP
            status is 200.
