Every CV edit is undoable on its own

Two hands edit a tailored CV: yours and the assistant’s. Until now you could see the result and nothing else. If the assistant rewrote eleven bullets and you disliked one of them, the only way back was to undo the whole run — losing the ten you were happy with.

The tailoring workspace has a History tab. Every change to the CV is an entry: who made it, when, what it changed, and a button that reverses that one edit and leaves the rest alone. Hovering an entry underlines what it touched in the live preview, so “what did it actually change” is answered by looking at the page rather than by reading a description of it.

• An assistant run folds into one entry you can undo whole — or open, to undo any single edit inside it.
• Undoing is itself recorded, so you can undo an undo, and the history keeps describing what really happened to the document.
• Your own edits are in there too. The history is of the CV, not of the assistant.

When the assistant explains why it made a change, that note sits under the entry in its own words — separate from the description of what changed, which is ours.
