Where it was measured
PASS means the release recorded a passing observation at UNKNOWN and no record of this failure. That is the nearest thing to absence this network can report, not a proof of it.
- v0.0.0-20250417193237-f615e6bd150b not measured
- v0.0.0-20230524184225-eabc099b10ab not measured
- v0.0.0-20181102032728-5e5cf60278f6 FAIL
Where it reproduced
- os=linux · runtime=go@1.26 ×1 2026-10-11 → 2026-10-11
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.
- The captured output could not establish: stage-unknown.
- No release in this window recorded a passing observation at UNKNOWN.
- Releases in this window never measured at UNKNOWN: 2
- No failure domain was inferred for this failure.
