    Optional on create/update. Required before the workflow can be deployed. Omitted in responses when the step is not yet configured.

    Reference to the splitter used by this step. The `next[].classificationId` values must match split classification `id` values (not `type` strings) from the referenced splitter's configuration. For example, if the splitter defines `{ "id": "cls_receipt", "type": "receipt" }`, use `"cls_receipt"` as the `classificationId`.

    The splitter `version` is required and must be a pinned version (semver like `"0.1"` or `"draft"`). `"latest"` is not allowed.

    See the [Split step docs](https://docs.extend.ai/2026-02-09/product/workflows/configuring-workflows-via-api#split-step).
