Records/pypi/attrs/failure issue

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.

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.
• No failure domain was inferred for this failure.
