Say that there are some local commits(A, A1, A2, A3) on the current detached HEAD which points to commit A, after repo sync, the local detached HEAD is overridden with the remote latest detached HEAD which points to commit B, what's the best way to find the old commits(A, A1, A2, A3)?

The simplest way I can imagine is:
git reflogto find A:
HEAD@{1}: checkout: moving from A to B
- Then you can do anything to A, like
- create a new branch for it in case missing it again:
git switch -c branchname A, or - rebase or merge it to the current HEAD:
git rebase A/git merge A, then you will see allA, A1, A2, A3appear on the current HEAD once all conflictions(if any) are resolved, and don't forget to create a new branch withgit switch -c.

If there were no additional operations that moved HEAD around, you could use HEAD@{1} to know the exact previous location of HEAD before current. Can use different numbers, of course:
git log HEAD@{1}
