History and undo
Every add, edit, status change and deletion of a task or a project is recorded — by the apps, with the device it came from (Mac, iPhone, iPad, and whether it was the widget), and by the agent API, with the agent's name.
Settings → History shows the timeline, each entry marked with a device icon or the assistant's logo, so "who moved this to Done" always has an answer.
On the Mac, ⌘Z and ⇧⌘Z undo and redo those changes — task edits, status moves, deletes and restores, links, projects. While you are editing a text field, that field's own undo runs instead. On iPhone, completing a task offers Undo in the toast for four seconds.
