我正在对分支 atomic_boron 上的代码进行一些补充。遇到错误后，我运行了命令：
git checkout HEAD^^
为了回到（大概）工作状态以确保它确实有效。但是，现在每当我运行时：
git checkout atomic_boron
它把我带到了旧的提交。但是， git log 显示较新的提交仍然存在。如果我签出最近的提交，它会让我进入一种我似乎无法摆脱的超然状态。在分离的头部状态下，我尝试运行：
git checkout -b wtf_detached_head
git checkout atomic_boron
git merge wtf_detached_head
但合并声称分支之间没有差异。
tl; dr：我想做的就是将 head 重新附加到 atomic_boron 上的最新提交，但 git 坚持以分离的 head 状态签出提交。
如果有帮助，这是 reflog 的输出：
