Risk: cautionRevert the Suspect Release Commit
The suspect release has already been shared, and you need a rollback commit that preserves branch history.
Command
cd /lab/git-recovery-rollback && git restore -- app/config.yml && git revert --no-edit release-2026-06-25-1030Before you run this
Risk: caution. 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
The dirty config line is discarded, then a new local revert commit is created inside the disposable demo repository.
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 fixture branch back one commit or recreate the fixture.
