 - **症状**: Node.js写入 ~/guanghulab/ 目录报 EPERM
 - **根因**: WorkBuddy sandbox 限制对用户目录的写操作
 - **修复**: 输出文件写入 workspace 目录 `/Users/.../WorkBuddy/.../outputs/`
-- **经验**: 文件输出默认放在当前工作区的 outputs/ 下。运行脚本时用 workspace 绝对路径。

+### Bug 8: Seedance版权过滤拦截
+- **症状**: API返回 `output video may be related to copyright restrictions`
+- **触发**: 提示词含具体设备名+破坏性动作（秦山号+砸液压装置）
+- **修复**: 去掉命名实体和暴力动词，换中性动作描述
+- **经验**: 命名实体+破坏动词=高风险。拆分镜时动作镜避免具体品牌/设备名。超过2次retry失败启用替代方案（黑场过渡）。

+### 第一集拼接
+- SG FFmpeg: `/usr/bin/ffmpeg` v6.1.1
