A merged PR broke main

Severity Serious

What just happened

The change passed review and CI but breaks something in main or in production. Reverting is the fastest safe way back.

Potential risks

Never reset or force push main: everyone has it.
To re-merge later, you'll need to revert the revert.

Before you run anything

Tell the team before acting.

Recovery steps

1
One click: Revert on the PR
Safe
At the bottom of the merged PR, “Revert” opens a new PR that cancels it.

2

Or by hand: merge commit

-m 1 keeps main as the main line.

Caution

$ git switch main && git pull
$ git revert -m 1 <merge-hash>
$ git push

3
By hand: squash-merged PR
It's a single normal commit: no -m needed.
Caution
```
$ git revert <squash-hash>
$ git push
```
