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.

• v1.21.0 FAIL

Where it reproduced

• executionContext=go · os=linux · runtime=go@1.26 ×1 2026-09-08 → 2026-09-08

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.
