Misattributed auto-revert — closing in favor of fix-forward. The cited red run failed on tests/unit/test_query_generation_preflight.py::test_tpcds_throughput_preflight_detects_generation_failures, which broke in #1093 when TPC-DS throughput preflight was rerouted to a batch dsqgen -STREAMS pass (the old test still injected via benchmark.get_query, a seam the new path never calls). The ~26min medium-test tier meant this red surfaced against later merges. Fixed forward and merged in #1113 — the cited failure no longer occurs on develop. Reverting this PR's target would not address the failure.
