这个报错不是 SAM3 代码本身的问题，ComfyUI Manager 在执行 git update 时读不到当前分支：

HEAD points to 'refs/heads/.invalid'

也就是说 ComfyUI/custom_nodes/ComfyUI-SAM3/.git/HEAD 已经坏掉了，Manager 还没真正拉取代码就失败了。

最稳的处理方式是重装这个 custom node：

1. 关闭 ComfyUI。
2. 删除这个目录：ComfyUI/custom_nodes/ComfyUI-SAM3
3. 重新安装，优先用 README 里的手动方式：

cd ComfyUI/custom_nodes
git clone https://github.com/PozzettiAndrea/ComfyUI-SAM3.git
cd ComfyUI-SAM3
pip install -r requirements.txt --upgrade
python install.py

如果你想先尝试修复现有目录，也可以在 ComfyUI-SAM3 目录里执行：

git symbolic-ref HEAD refs/heads/main
git fetch origin
git checkout main
git pull

但如果 .git 里还有别的损坏，直接删除目录后重新 clone 会更干净。
