• Reversible actions and the value of keeping exactly one previous version

  An action is reversible when a recorded way back exists before it runs: a previous version, a revert commit, a rollout to the prior revision; keeping exactly one fallback version, as this wiki does, covers the most common mistake (the last change) at bounded cost, but the safety net is consumed by the next change, so verify before editing again.
