Read-only

Revert the Suspect Release Commit

The suspect release has already been shared, and you need a rollback commit that preserves branch history.

Command

git restore -- app/config.yml && git revert --no-edit release-2026-06-25-1030

Before you run this

System impact: Read-only. Low when scoped to the shown target.

When not to use it: Do not use revert blindly when the bad release included database migrations or external side effects that need a separate rollback plan.

Expected output

Git restores the dirty file, creates a revert commit, and the recent log shows the new Revert commit above the suspect release.

System impact

Read-only. The dirty config line is discarded, then a new local revert commit is created inside the local repositorysitory.

When to use it

Use when a bad commit is already published or shared and rollback should be represented as a forward-moving commit.

When not to use it

Do not use revert blindly when the bad release included database migrations or external side effects that need a separate rollback plan.

Recovery / rollback

Reset the disposable example branch back one commit or recreate the example.

Diff Restored Config Against Expected

A restored config can exist and still be the wrong config.

A file list says what exists; checksums say whether bytes match.

Map Recent Release Commits

A rollback is easier when the last few release tags are visible.

git log --oneline --decorate --graph --all -8
Study mapping

Use this as independent command practice: read the notes, predict the output, then compare it with the example before using a real shell.
