Confidence Score: 4/5

The PR appears safe to merge, with a non-blocking environment-ordering issue that can undermine the Autobahn parallel-mode override in externally configured test environments.

The existing CI does not define the conflicting environment variable and the coverage artifact paths remain consistent, but both Autobahn subprocess environments allow an inherited value to replace the explicit false setting.
