+# ------------------------------------------------------------------------------
+# Scan older GitLab releases for a matching asset (fallback helper).
+#
+# Description:
+#   When the latest release does not contain the expected asset
+#   (e.g. .deb for the current arch, or a custom pattern), walks back
+#   through up to 15 recent releases and returns the first release JSON
+#   that has a matching asset. Used internally by fetch_and_deploy_gl_release.
+#
+# Usage (internal):
+#   _gl_scan_older_releases "owner/repo" "owner%2Frepo" "https://gitlab.com" \
+#     "binary|prebuild|singlefile" "$asset_pattern" "$skip_tag"
+#
+# Returns:
+#   - stdout: JSON of the matching release (single object) on success
+#   - 0 on success, 22 on API error, 250 if no match found
