Review Comment:
In Spark's `AttributeReference`, the `name` field doesn't include the
`#exprId` suffix — that's stored as a separate field and only appears in
`toString`. Is there a specific scenario where `ref` would actually contain
`#digits` here? If not, this `replaceAll` might be misleading to future readers.
