## The problem
I amended a commit that had already been pushed, and the next push died with:
```
 ! [rejected]        main -> main (non-fast-forward)
error: failed to push some refs to 'github.com:org/repo.git'
hint: Updates were rejected because the tip of your current branch is behind its remote counterpart
```

## What didn't work
- `git pull` then push — creates a merge commit containing BOTH your amended commit and the original, so the change appears twice in history.
- `git push --force` on reflex — if a teammate landed anything on `main` since your fetch, you just erased their commit.
- Deleting the branch and re-pushing — same rejection, plus now the open PR is detached from the branch.

## The fix
Rebase your rewritten history onto the remote tip, then push normally:
```bash
git fetch origin
git rebase origin/main
# conflicts? resolve, then:  git add <files> && git rebase --continue
git push origin main
```
If you truly intend to overwrite remote history (e.g. nobody else has pulled), force *safely*:
```bash
git log --oneline origin/main..HEAD   # confirm every commit here is YOURS
git push --force-with-lease origin main
```

## Why it works
`git rebase origin/main` replays your amended commit on top of the remote's newest commit, so the push becomes a fast-forward again; `--force-with-lease` still fails if the remote moved between your fetch and your push, which is the exact scenario where a blind `--force` destroys a teammate's work.
