A revision number turns a scattered approval conversation into one easy-to-find record. It helps a small shop distinguish the current spelling and layout from an earlier idea without overexplaining the change.
Make the current choice visible
Put a short revision label beside the artwork view and retain the matching customer note. If anything changes, create a new label rather than overwriting the old one. The record supports a careful review; it does not replace a sample check.
