The end of a role is a strange test of professionalism. It is easy to treat the last few days as already gone, especially when the ending is not the one you would have chosen.
But the last handoff still counts. The open loops, the context that only lives in your head, the risks you know about, the small decisions someone will need to explain next month. Leaving those behind clearly is not about being performative. It is about respecting the work and the people who will keep carrying it.
Reputation is not only built in the visible wins. It is also built in the exits. Write the notes. Name the loose ends. Make the next person less surprised than they would have been.
