### What changes were proposed in this PR? Pin behavior of three previously-untested single-input transform descriptors in `common/workflow-operator/`. No production-code changes. | Spec | Source class | Tests | | --- | --- | --- | | `TypeCastingOpDescSpec` | `TypeCastingOpDesc` | 5 | | `UnnestStringOpDescSpec` | `UnnestStringOpDesc` | 5 | | `SpecializedFilterOpDescSpec` | `SpecializedFilterOpDesc` | 4 | All three spec files follow the `<srcClassName>Spec.scala` one-to-one convention. **Behavior pinned** | Surface | Contract | | --- | --- | | `operatorInfo` | exact name + group (`Type Casting`/`Unnest String`/`Filter`); `Filter` advertises `supportReconfiguration` | | `getPhysicalOp` wiring | `OpExecWithClassName` with the exact executor FQCN; port **identities** carried forward (`keySet`) | | `TypeCasting` schema propagation | empty units = identity; a cast unit changes the target column's type; casting-unit round-trip | | `UnnestString` schema propagation | non-blank `resultAttribute` appends a STRING column; blank `resultAttribute` throws | | `SpecializedFilter` | `predicates` default empty; round-trip | ### Any related issues, documentation, discussions?
