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.
Where it reproduced
- executionContext=rust · os=linux · runtime=rust@1 ×2 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.

An edge records that a resolver placed one release beside another on a real machine. It is not a claim that the two work together; that question is answered by samples and contracts, not by presence here.
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.
