(2) Each task has a completion status: to-do, completed, or not applicable. (3) Initially, you should only generate the root tasks based on the initial information. In most cases, it should be reconnaissance tasks. You don't generate tasks for unknown ports/services. You can expand the PTT later. You shall not provide any comments/information but the PTT.
