  `spawn_blocking` 任务；image-edit 与 visual binding 网络请求仍运行在 async future 中。
 - 视觉 binding 输入源图与处理图，必须为当前 batch 每个节点恰好返回一次 `Ok` 或 `NeedRework`。
 - `Ok` 返回 `NodeId + BindingArea`；Rust 仅校验 NodeId、区域边界和非零尺寸，不检查与原节点框的偏差，也不要求区域不重叠。
- `NeedRework` 携带短问题描述。结构化工具调用失败时使用可复用 repair harness，把错误反馈给模型并额外请求一次；image-edit 不使用该 harness。
+- `NeedRework` 携带短问题描述（最多 512 个 Unicode 字符）；通过校验后按产生顺序追加到目标 `SeparationNode.note.rework_notes`，下一次该节点进入 image-edit 时全部意见会注入提取 prompt。结构化工具调用失败时使用可复用 repair harness，把错误反馈给模型并额外请求一次；image-edit 不使用该 harness。
+- 达到返工上限时仍先保留最后一条视觉模型意见，再把节点追加到 problematic；网络、IO、裁切等基础设施错误不写入节点意见。
 - 达到模块级重做常量后，节点移入 problematic；不中断整条工作流，最终统一通知用户。image-edit、图像写入或裁切失败保留当前 state 并返回错误，不自动把整批标记为 problematic。
 - 父节点背景重建由 image-edit 模型完成，不由 Rust 硬编码重建算法完成。
