+# PR Quality Gates — caller for the org-wide reusable workflow.
+# Provides:
+#   - PR size labeling (warn over 500 lines, alert over 1000)
+#   - Auto-approve for maintainer PRs (OWNER/MEMBER/COLLABORATOR), so
+#     branch-protection or Copilot-ruleset approval gates don't block
+#     trivial maintainer work; Copilot review still runs separately
+#     via the Copilot ruleset (not via this workflow).
+# Reusable: netresearch/.github/.github/workflows/pr-quality.yml
