Establish whether the observed SWE-bench discrepancies are genuine defects

Determine whether the private-helper and unsupported-input differences reproduced for Requests issue 2931 and SymPy issue 24066 constitute genuine defects or acceptable behavior under the intended specifications.

Background

The exploratory SWE-bench review conducts targeted executions for nine cases with archived execution narratives. Six cases confirm behavior supported by issue reports or documentation, but two cases—Requests 2931 and SymPy 24066—reproduce differences involving a private helper or unsupported inputs without resolving whether those differences indicate defects. The authors therefore leave the interpretation of these cases open.

References

Requests 2931 and SymPy 24066 reproduce private-helper or unsupported-input differences whose defect interpretation remains unresolved.
