Head commit for run: 324278eba8ad915a62c0736936ca368aee59b020 / Xinyuan Lin <[email protected]> chore(workflow-operator): remove the unused ProgressiveUtils (#7619) ### What changes were proposed in this PR? Deletes `ProgressiveUtils` and its spec — the insert/retract flag helper for the old progressive-sink path, whose consumers were removed long ago. Pure deletion, no behaviour change: **−282 lines**. All four public methods (`addInsertionFlag`, `addRetractionFlag`, `isInsertion`, `getTupleFlagAndValue`) have no caller outside the object's own spec. The marker attribute the helper is built around, `__internal_is_insertion`, appears nowhere else in the repository — no operator, no storage reader, no frontend code, no test fixture. Nothing produces or consumes tuples carrying that flag, so the helper is unreachable even indirectly. > Reviewer note: it acquired unit tests during the 2026 coverage work, which is why it currently looks live. The spec covers this object and nothing else, so it goes with it. ### Any related issues, documentation, discussions? Closes #7616 ### How was this PR tested? Existing tests only — this PR adds none, since it removes code and the spec that covered it. Locally, from the repo root with Java 17: - `sbt "WorkflowExecutionService/Test/compile"` — success (main and test sources). Verification, re-runnable by a reviewer: ``` git grep -n ProgressiveUtils # only the two deleted files git grep -n __internal_is_insertion # only the two deleted files ``` ### Was this PR authored or co-authored using generative AI tooling?
