Version control…
Write it in your own words in the app.
In real work
Use version control history to see which agent commit introduced the regression.
In the illustration
Each save stamps a new plate, 1 to 5; plate 5 shows a crack, so the carriage rolls back and restores plate 4 while 5 stays on record.
Use version control in your coding agent to save my work: a branch for this fix, a commit message that says what changed, and the command to push it.
