Hard to Read, Hard to Maintain? Refactoring Complex SQL into Wvlet Pipelines
Summary: WCW refactors complex analytical SQL into more readable, maintainable Wvlet pipelines via duplicate extraction and safe join flattening. It uniquely combines side-by-side readability metrics, semantic-equivalence checking, and workload-level shared-model extraction. (summarized by gpt-5.6-luna on Aug 28 2026)
