  "documentation": "# DashScope Wan 3.0 Video\n\n该目录是独立官方协议插件源码。后端从生成的 `dashscope-wan3-video.yingce-plugin` 包加载，不依赖系统内置 `host:` 适配器。\n\n完整接口见 [docs/interface.md](docs/interface.md)。\n\n---\n\n# DashScope Wan 3.0 Video 接口字段\n\n## 协议身份\n\n- 插件 ID：`dashscope-wan3-video`。\n- Provider ID：`dashscope-wan3-video`。\n- 能力：`video`。\n- 默认 Base URL：`https://dashscope.aliyuncs.com`。\n- 鉴权驱动：`bearer`。\n- 创建：`POST /api/v1/services/aigc/video-generation/video-synthesis`。\n- 查询：`GET /api/v1/tasks/{{taskId}}`。\n\n## 配置字段\n\n| 字段 | 类型 | 必填 | 含义 |\n| --- | --- | --- | --- |\n| `apiKey` | secret | 是 | API Key |\n\n## 统一字段映射\n\n| 统一字段 | 类型 | 必填 | 上游映射 | 说明 |\n| --- | --- | --- | --- | --- |\n| `model` | string | 是 | `model` | 视频模型 ID。 |\n| `prompt` | string | 是 | `prompt/content/input` | 视频提示词。 |\n| `images` | media[] | 否 | `first/last/reference image` | 显式 role 图片输入。 |\n| `videos` | media[] | 否 | `reference video` | 参考视频。 |\n| `audios` | media[] | 否 | `reference audio/voice` | 参考音频或音色。 |\n| `duration` | integer | 否 | `duration/seconds` | 时长秒数。 |\n| `aspectRatio` | string | 否 | `ratio/aspect_ratio/size` | 画幅比例或尺寸。 |\n| `resolution` | string | 否 | `resolution` | 分辨率档位。 |\n| `generateAudio` | boolean | 否 | `generate_audio` | 是否生成音频。 |\n| `watermark` | boolean | 否 | `watermark` | 水印开关。 |\n| `providerOptions` | object | 否 | `provider-specific fields` | 插件命名空间内的厂商扩展字段。 |\n\n## 上游请求模板逐字段清单\n\n下表由插件请求模板生成，覆盖 body、query、headers 和 multipart 文件声明中的每个字段。\n\n| 上游位置 | 值或转换表达式 |\n| --- | --- |\n| `create.method` | `\"POST\"` |\n| `create.path` | `\"/api/v1/services/aigc/video-generation/video-synthesis\"` |\n| `create.contentType` | `\"application/json\"` |\n| `create.body.model` | `{\"$ref\":\"request.model\"}` |\n|

`providerOptions.dashscope-wan3-video.seed`\n\n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。\n\n## 响应映射逐字段清单\n\n| 映射位置 | 上游路径或转换表达式 |\n| --- | --- |\n| `response.taskId` | `{\"$coalesce\":[{\"$ref\":\"response.output.task_id\"},{\"$ref\":\"response.task_id\"},{\"$ref\":\"taskId\"}]}` |\n| `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\"]}}}`

`{\"$ref\":\"response.usage\"}` |\n| `response.messagePaths[0]` | `\"message\"` |\n| `response.messagePaths[1]` | `\"output.message\"` |\n\n## 响应与错误\n\n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。\n\n## 兼容边界\n\n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。\n\n<!-- YINGCE_MANIFEST_CONTRACT_START -->\n## Manifest 完整接口定义\n\n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。\n\n```json\n{\n
