+

+   upload/download prefix (``project/<sha>/...``). Suffixing it for v2 jobs only
+   routes v2 binaries to a distinct s3 key namespace without renaming build_dir.
+
+3. Redefine ``generate_pytest_child_pipeline`` so its script also runs
+   ``patch_buildv2_target_test_pipeline.py`` against the emitted

+   ``PIPELINE_COMMIT_SHA`` override into each target_test job. Without this, the
