Your unit will hand you a stack of out-processing forms and a checklist that focuses almost entirely on turning in gear and clearing your section. It says almost nothing about the administrative decisions that follow you into civilian life: whether your final medical exam actually captures every condition, how terminal leave interacts with your last paycheck, and whether the DD-214 you get on your last day is even correct.
None of this is hidden from you on purpose. It's just spread across a dozen offices, none of which is responsible for the whole picture. This is the version of the checklist that connects the pieces.
