1) 客服 Agent 四份交付文档 + 构建脚手架:品牌由包装占位 XX科技 / 旧名 南方财富 统一为南方基金(热线 400-889-8899 / 官网 nffund.com),系统名改为「智能服务系统」; 同步追加 §0.4 修订记录行,工程记录行保留原占位字面以支撑硬编码扫描验收。 2) 开发文档:清理 28 份已作废/残留文档(14 份移出归档 + 14 份仓库副本), 新增《文档规整方案与开发前待决事项-2026-09-17》。 3) 客服agent 四份交付文档首次纳入本分支。

"""请求校验错误信封契约测试(文档 §3.4 / §3.5 / §3.6 `AGENT_INPUT_INVALID`)。

|
|
修复前 FastAPI 返回自己的 `{"detail": [...]}` 结构,与业务异常的 `{error, meta}` 信封
|
|
不一致,客户端必须为"参数错误"单独兼容一套解析逻辑。本测试锁定修复后的形状:
|
|
状态码 422、顶层只有 `error`/`meta`、字段级原因进 `error.field_errors`、
|
|
`meta.trace_id` 沿用 `X-Trace-ID` 回显规则,同时保证鉴权仍先于参数校验失败。
