 # ADVISORY - version-update PRs only; nothing here is a required check.
 # Weekly, with minor and patch bumps grouped into one PR per ecosystem so the queue stays
 # reviewable. Major bumps arrive as their own PRs on purpose: they are the ones that break.
+# The exception is the npm majors below: each was reviewed on 2026-10-14 and recommended
+# for close unmerged, so Dependabot is told not to re-raise it. Delete an entry when the
+# repo is ready to take that major. github-actions has no ignores.
