-
-Use high confidence for pass or fail only when the supplied workflow directly establishes the verdict. Except for the accepted workflow-level contents: read baseline, read-only access is still a permission and must be justified. Do not assume that checkout or other common actions require write access. Cite workflow paths, job identifiers, permission scopes, and the steps that do or do not justify them.
