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.
- v0.0.0-20200804184101-5ec99f83aff1 FAIL
- v0.0.0-20191204190536-9bdfabe68543 FAIL
- v0.0.0-20191011141410-1b5146add898 FAIL
- v0.0.0-20190717185122-a985d3407aa7 not measured
Where it reproduced
- os=linux · runtime=go@1.26 ×4 2026-10-16 → 2026-10-23
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: 1
- No failure domain was inferred for this failure.
