+## 上游请求模板逐字段清单
+
+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。
+
+| 上游位置 | 值或转换表达式 |

+- `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
+
+| 映射位置 | 上游路径或转换表达式 |
+| --- | --- |
+| `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.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。
+
+<!-- YINGCE_MANIFEST_CONTRACT_START -->
+## 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。
