        The request body is a source object without the `id` field. If an

        `id` is sent anyway it is silently ignored (stripped before

        validation — the request is never rejected because of it).

        Granularity fields

        (`materializedViews[].minGranularity` and

        `metadataMaterializedViews.granularity`) accept the same short format

        the API returns (e.g. `5m`, `15s`, `1h`, `1d`).
