Where it was measured
PASS means the release recorded a passing observation at PROJECT_PROCESS and no record of this failure. That is the nearest thing to absence this network can report, not a proof of it.
- 8.0.1 PASS 34 passing observations
- 8.0.0-rc.6 PASS 56 passing observations
- 7.29.7 FAIL
- 7.29.6 PASS 30 passing observations
- 7.28.5 PASS 11 passing observations
- 7.27.4 not measured
- 7.24.7 PASS 6 passing observations
- 7.24.0 PASS 11 passing observations
- 7.22.5 FAIL

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 failing release 7.22.5 → first passing release 7.24.0
What differs across the boundary
- convert-source-map 2.0.0 → 1.9.0 hypothesis
A version that moved across the boundary is a candidate, not a cause. Only a receipt that recorded the failure and the tree it resolved in the same run is marked as evidence.

- @babel/parser 7.29.8 → 7.29.7, 7.29.8 hypothesis

Dependency versions across releases
What each release of this package resolved its children to. A child whose version moved is listed first: that is where an upgrade changed something underneath you.
Moved: 11 · unchanged at every release: 12
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.
- Releases in this window never measured at PROJECT_PROCESS: 1
- No failure domain was inferred for this failure.
