定义

interface Issue

字段结构

字段	类型	必需	说明
code	string	必需	只读。Stable machine-readable reason code; the primary key for programmatic handling.
message	string	必需	只读。Human-readable description; not guaranteed stable for matching.
path	readonly (string | number)[] | undefined	可省略	只读。Path of the offending field inside the checked value, outermost segment first.
checkId	string | undefined	可省略	只读。Registered check that produced the issue, when the check belongs to a catalog.

使用示例

• 尝试预算与错误归属：将尝试次数、数据无效和流程合同错误分别表达，不把所有失败都转成成功正文。

只给两次业务尝试
