### Task Summary Three machine-learning operator types under `common/workflow-operator/machineLearning/` have no `<srcClassName>Spec.scala`. ### Scope | Source class | Lines | What's currently un-pinned | | --- | --- | --- | | `machineLearning/Scorer/MachineLearningScorerOpDesc.scala` | 194 | operatorInfo (`Machine Learning Scorer`); `getOutputSchemas` derives metric columns (regression vs classification); round-trip | | `machineLearning/sklearnAdvanced/base/HyperParameters.scala` | 69 | generic config bag — `parameter`/`attribute`/`value` null defaults + `parametersSource`; `@JsonProperty` wire-keys + `Include.NON_NULL` serialization; round-trip | | `machineLearning/sklearnAdvanced/base/SklearnAdvancedBaseDesc.scala` (`SklearnMLOperatorDescriptor`) | 175 | abstract base — operatorInfo derived from the subclass's `getOperatorInfo` (ADVANCED_SKLEARN_GROUP, two inputs training/parameter + one output); fixed `getOutputSchemas`; base-field defaults. Tested through a real concrete subclass (no stub — avoids the classpath-scanner concern) | ### Out of scope No production-code changes. One `<srcClassName>Spec.scala` per source class. ### Task Type - [x] Testing / QA -- This is an automated message from the Apache Git Service.
