git bisect: Find the Commit That Broke Everything

The article explains how `git bisect` uses binary search to find the first bad commit that introduced a bug.

It walks through starting from known good and bad revisions, then testing each midpoint manually or with `git bisect run`.

It also covers how to skip hard-to-test commits and what to do when the identified commit needs a closer review.

After `git bisect` narrows it down, you can inspect the commit with `git show` or `git log` to confirm the root cause.
