Where it was measured
PASS means the release recorded a passing observation at PROJECT_TEST and no record of this failure. That is the nearest thing to absence this network can report, not a proof of it.

Nearest known PASS/FAIL boundaries
No release either side of this failure recorded a passing observation at this stage, so where it starts and stops is not established.
Evidence gaps
- The evidence for this failure was not preserved, so it has no established cause. Its stored hash is provenance, not an identity.
- No release in this window recorded a passing observation at PROJECT_TEST.
- No failure domain was inferred for this failure.
Published answers for the affected releases
- joblib 1.5.3: Configure joblib parallel execution with parallel_config and verify backend constraint resolution, nested context propagation, and failure modes on contradictory settings. This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
