### Task Summary `amber/src/main/python/core/models/operator.py` exposes the `Operator` abstract base class plus `TupleOperatorV2`, `SourceOperator`, `BatchOperator`, and `TableOperator`, but has no dedicated spec. Add unit tests covering `PythonTemplateDecoder` (default and pluggable base64 decoders, lru-cache reuse), `is_source` property/setter, default no-op methods (`open`, `close`, `process_state`, `produce_state_on_start`, `produce_state_on_finish`), the lazy `_get_template_decoder`, and `BatchOperator._validate_batch_size` (None / non-int / non-positive / positive). ### Task Type - [x] Testing / QA -- This is an automated message from the Apache Git Service.
