Resolution states

The type of task determines the possible resolution states a task can be in and the interface shown to a user in the web and mobile apps.

A review task starts out in an incomplete state and can be marked as incomplete, approved, or rejected. In the user interface a user is provided with a text box and an pair of buttons to approve or reject the task.

A complete task starts out in an incomplete state and can be marked incomplete or completed. Once a this task is marked completed, no further changes can be made to the task's state. In the user interface a user is provided with a text box and an button to mark the task as completed.
