¶ Archive
Open in CRM: /tasks/board/9660/archive
Finished tasks of a board: Status, Title, Priority and the rest of the card's fields.
A completed task leaves the board but not the system. The archive is where it goes, and it is the answer to was this ever done and by whom — a question that comes up long after the card stopped being interesting.
Restoring a task back to work requires TASK_RESTORE, or being the person who created it.
