Versions and undoing changes

Every time a document is updated, Profusia keeps the previous version. Nothing is overwritten. To go back, ask your assistant to roll the file back (rollback_file) to an earlier version, or do it yourself: open the document in Docs, and its panel has a Version history section listing every version with its date, who made it and any note they left. Press Restore — it asks you to confirm with a second press, then makes that version current. Restoring never deletes anything: the version you were on stays in the list, so a restore can itself be undone. The share link doesn't change, so anyone holding it sees the restored content.
