### Rationale for this change A Null `typed_value` column is not a valid shredded Variant type. Nulls are encoded in the `value` column as Variant null (`00`). A dedicated Null `typed_value` would also make “field present and null” indistinguishable from “field missing” for shredded objects. See apache/arrow#50622 and apache/arrow#50810. Fixes #1205 ### What changes are included in this PR? - `NewVariantType` rejects a Null `typed_value` field - Nested shredded fields with a Null `typed_value` are also rejected ### Are these changes tested? - `go test ./arrow/extensions` ### Are there any user-facing changes? Yes — constructing a Variant extension type with a Null `typed_value` now returns `arrow.ErrInvalid`.
