Where it was measured
PASS means the release recorded a passing observation at PROJECT_COMPILE and no record of this failure. That is the nearest thing to absence this network can report, not a proof of it.
- v0.24.0 PASS 1 passing observations
- v0.23.0 not measured
- v0.22.0 FAIL
- v0.21.0 not measured
- v0.20.0 FAIL
- v0.19.0 PASS 1 passing observations
- v0.18.0 PASS 3 passing observations
- v0.17.0 FAIL
- v0.12.0 PASS 2 passing observations
Where it reproduced
- os=linux · runtime=go@1.26 ×3 2026-08-31 → 2026-09-19
Nearest known PASS/FAIL boundaries
The two adjacent releases the verdict changes across. Releases nothing measured do not close the gap; they are counted instead.
-
Last passing release v0.12.0 → first failing release v0.17.0
One side of this boundary has no resolved dependency tree, so nothing could be compared.
-
Last failing release v0.17.0 → first passing release v0.18.0
One side of this boundary has no resolved dependency tree, so nothing could be compared.
-
Last passing release v0.19.0 → first failing release v0.20.0
One side of this boundary has no resolved dependency tree, so nothing could be compared.
-
Last failing release v0.22.0 → first passing release v0.24.0
Releases between them never measured at this stage: 1
One side of this boundary has no resolved dependency tree, so nothing could be compared.
Evidence gaps
- Releases in this window never measured at PROJECT_COMPILE: 2
- No resolved dependency tree for v0.12.0 or for v0.17.0, so the versions either side of the boundary could not be compared.
- No failure domain was inferred for this failure.
