 ### Added / 新增
 
 - 非视觉模型收到图片时不再直接报错丢图：宿主以 `MODEL_DOES_NOT_SUPPORT_IMAGES` 拒绝带图片的 prompt 后，自动把同一批图片字节按入站文件管线落盘到 Session 工作区，并以"原文本 + 工具分析指引 + `<dsh_im_files>` 清单"的纯文本 prompt 复用同一 rpcId 重试一次，使非视觉模型仍可通过 run_code/pwsh 等工具识图；视觉模型与文件消息行为不变，其余图片错误仍按原样提示。
   Sending an image to a non-vision model no longer fails outright: when the Host rejects an image-bearing prompt with `MODEL_DOES_NOT_SUPPORT_IMAGES`, the same image bytes are automatically staged into the Session workspace through the inbound-file pipeline and retried once as a text-only prompt (original text plus tool-analysis guidance and the `<dsh_im_files>` manifest) under the same rpcId, so non-vision models can still inspect images via tools such as run_code/pwsh. Vision models and file messages are unchanged, and other image errors keep their existing messages.
 
+- 九个 IM 渠道统一支持引用或回复消息上下文：Harness 会在当前问题之前收到安全序列化的 `<dsh_im_reply_to>`，包含平台可提供的原消息文字、作者及附件类型/名称；缺少正文快照的渠道仅在访问控制和本地交互完成后进行同会话、有界的延迟查询或 Session 历史恢复，失败时不阻断当前问题，也不会把引用内容误当作命令、审批或问题回答。
+  All nine IM channels now preserve quoted or replied-to message context. Harness receives a safely serialized `<dsh_im_reply_to>` before the current question with the original text, author, and attachment type/name when available. Channels without a content snapshot perform only bounded, same-conversation lazy lookup or Session-history recovery after access control and local interactions; lookup failure does not block the current question, and quoted content cannot be interpreted as a command, approval, or question answer.

 - 非视觉模型图片回退在文件落盘阶段收到取消信号时，现在会保留调用方的取消原因并停止处理，不再误报模型不支持图片。
