## 5.5.2

**`(fix):`** Fix generated wire tests and dynamic snippets to honor `pydantic_config.union_naming: v1`.
Previously, variant class names in wire tests and README/reference snippets were always
emitted with the v0 suffix style (e.g. `UnionName_Variant`), causing import errors when
the SDK types were generated with v1 prefix-style names (e.g. `VariantUnionName`).
