 ✅ sed 就地修改 → 更新 videos.json videoUrl
 ⚠️ 前端部署 → Nginx root路径 + fetch路径对齐（已踩坑）

+### Bug 6: duration参数被忽略 → 始终5秒
+- **症状**: 请求10秒视频，API返回5秒。所有请求: resolution=1080p但实际=720p
+- **根因**: 旧版API格式 `parameters: { video_length: "10" }`，Seedance 2.0的duration在顶层 `{ duration: 10 }`
+- **修复**: 修改 `submitTask()` payload: 移除 `parameters` 包装，`duration` 直接放在根级
+- **验证**: 修复后10秒视频生成成功（4.4MB vs 修复前2.2MB）
+- **经验**: API每个大版本都可能改参数位置。对照官方curl示例验证payload格式。
+
+### Bug 7: sandbox EPERM 阻止文件写入
+- **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。
