### What changes were proposed in this PR? Pin behavior of three previously-untested descriptors that reorder rows or combine relations, in `common/workflow-operator/`. No production-code changes. | Spec | Source class | Tests | | --- | --- | --- | | `StableMergeSortOpDescSpec` | `StableMergeSortOpDesc` | 3 | | `SortPartitionsOpDescSpec` | `SortPartitionsOpDesc` | 3 | | `SymmetricDifferenceOpDescSpec` | `SymmetricDifferenceOpDesc` | 4 | All three spec files follow the `<srcClassName>Spec.scala` one-to-one convention. **Behavior pinned** | Surface | Contract | | --- | --- | | `operatorInfo` | exact name + group (`SORT_GROUP` / `SET_GROUP`); blocking output port (sort/set must observe all rows); `SymmetricDifference` advertises two inputs `PortIdentity(0)`/`PortIdentity(1)` | | `getPhysicalOp` wiring | `opExecInitInfo` pattern-matches `OpExecWithClassName` with the exact executor FQCN; port **identities** carried forward (`keySet`, not counts) | | `StableMergeSort` | non-parallelizable many-to-one op; deserializes its `List[SortCriteriaUnit]` sort keys | | `SortPartitions` | `RangePartition(List(attr), domainMin, domainMax)` partition requirement; field round-trip | | `SymmetricDifference` | `HashPartition` requirement on both inputs; schema propagation passes the shared input schema through and throws `IllegalArgumentException` when the two inputs' schemas differ | ### Any related issues, documentation, discussions?
