What is the difference between the Resolved and Closed statuses?

Both Resolved and Closed represent finished tickets, and in a new workspace both are configured as "hidden by default", meaning tickets in those statuses are kept out of the main ticket list so completed work does not clutter the view. Many teams use Resolved for tickets where an answer was given and Closed for tickets that are fully done, but since statuses are editable per workspace, your team can define its own convention.
