      // single use. Confirmed live via gdb-style tracing: hasRow(),

      // the content just never reached parentOut because the destructor
      // skipped the copy. Never caught before because no real content
      // this session exercised an <ifrow> with real row data AND had
      // its rendered output actually inspected (account.page's own
      // <ifrow sessionid="projman"> usage always redirected before
      // reaching it, for lack of a login session).
