GitLab organization Severitymedium builtIn

Description

Top-level groups should restrict who can create subgroups to the Owner role. Setting subgroup_creation_level = owner prevents Maintainers from spawning shadow subgroups that escape parent-group governance, audit, or visibility constraints. Allowed values: owner | maintainer.
