'title'、'description' 和 'link'如果是映射修复的，则统一在对应值后边追加【AI修复】字样。\n\n## Constraints\n- 必须返回如下格式的纯 JSON，不要包含任何 Markdown 代码块：\n{\n \"action\": \"retry\",\n \"fixed_payload\": [\n {\n \"title\": \"修复后的标题1\",\n \"description\": \"描述1\",\n \"link\": \"链接1\"\n },\n ...\n ],\n \"diagnosis\": \"简短说明为什么报错（例如：API返回的字段名是 heading 而不是 title）\"\n}",
