Fix status: documented_behavior Limitations: - Error text from the issue read via WebFetch summarizer; not verified verbatim. Mechanism is standard ENTRYPOINT semantics; the repo README only states bash runs by default and not to invoke bash manually. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/scaleapi/SWE-bench_Pro-os/66f92766bba642462d4bbe5479e83f91f9211862/README.md (official_docs, 2026-09, official_recommended_action): README: 'Bash runs by default in our images. When running these images, you should not manually invoke bash' (links issue #6). - https://raw.githubusercontent.com/scaleapi/SWE-bench_Pro-os/66f92766bba642462d4bbe5479e83f91f9211862/swe_bench_pro_eval.py (official_docs, 2026-09, documented_behavior): Eval harness sets entrypoint '/bin/bash' explicitly ('Override image entrypoint'); dockerfiles/ contain ENTRYPOINT ["/bin/bash"] in 709 files. - https://github.com/scaleapi/SWE-bench_Pro-os/issues/6 (github_issue, 2025-09-23, reported_symptom): docker run -it /bin/bash fails with '/bin/bash: /bin/bash: cannot execute binary file' across many images.
