+name: Dual Approval Check

+# Reusable workflow: verifies that both the CTO and QA bot accounts
+# have approved a pull request. Plugin repos call this on
+# pull_request_review events to get a required GitHub status check.

+# Usage in a plugin repo's workflow:
+#
+#   on:
+#     pull_request_review:
+#       types: [submitted, dismissed]
+#     pull_request:
+#       types: [opened, reopened, synchronize]
+#
+#   jobs:
+#     dual-approval:
+#       uses: privilegedescalation/.github/.github/workflows/dual-approval-check.yaml@main
