+# Tests the documented installation flow:
+#   curl -s https://raw.githubusercontent.com/ProxySQL/dbdeployer/master/scripts/dbdeployer-install.sh | bash
+#
+# This catches release-asset mismatches (wrong file naming, missing
+# checksums.txt, missing tarballs) that would break the install script
+# for end users. Runs automatically after a release is published, on a
+# weekly schedule, and on manual dispatch.
+#
+# Security note: this workflow uses no user-controlled inputs (issue
+# bodies, PR titles, commit messages, etc.). The matrix values are
+# hardcoded here and matrix.os is safe to interpolate.
