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 not measured
• v0.0.0-20191204190536-9bdfabe68543 FAIL
• v0.0.0-20191011141410-1b5146add898 not measured

Where it reproduced

• os=linux · runtime=go@1.26 ×1 2026-09-19 → 2026-09-19

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.
