Provider 扩展键

providerOptions.dashscope-wan3-video.audio
providerOptions.dashscope-wan3-video.media
providerOptions.dashscope-wan3-video.prompt_extend
providerOptions.dashscope-wan3-video.seed

动态模型或工作流允许使用文档声明的完整 parameters/input/extra_body 对象；该对象是协议本身的开放 schema，不会被宿主裁剪。

响应映射逐字段清单

`response.taskId`	`{"$coalesce":[{"$ref":"response.output.task_id"},{"$ref":"response.task_id"},{"$ref":"taskId"}]}`
`response.status`	`{"$if":{"condition":{"$eq":[{"$lower":{"$ref":"response.output.task_status"}},"unknown"]},"then":"failed","else":{"$coalesce":[{"$ref":"response.output.task_status"},{"$ref":"response.status"},"pending"]}}}`

`response.resultEphemeral`	`true`
`response.usage`	`{"$ref":"response.usage"}`
`response.messagePaths[0]`	`"message"`
`response.messagePaths[1]`	`"output.message"`

响应与错误

插件把上游 task/status/text/media/usage 映射为统一结果。临时媒体 URL 标记为 ephemeral，由宿主立即下载持久化。HTTP 错误、业务 code 和 error object 保持失败语义，不包装成成功。

兼容边界

该包只代表上述线协议 profile；同一品牌的其他 endpoint、云区域或网关包装必须使用独立插件，不能根据模型名猜测。

Manifest 完整接口定义

以下 JSON 与插件包内实际 manifest.json 逐字段一致，覆盖插件身份、权限、配置、鉴权、参数、校验、创建、Agent、查询、取消、结果下载、响应和 Agent 响应映射。documentation 字段的值就是当前完整文档；为避免文档在自身内部无限递归，JSON 中仅用等义占位文本表示正文。
