Manager thinks they're getting a functional close button. What they're actually getting is a button that terminates the entire application with extreme prejudice. No cleanup, no graceful shutdown, just straight to the shadow realm. The developer's uncomfortable side-eye says it all. Sure, it closes the app. Technically correct is the best kind of correct, right? Hope nobody was in the middle of saving anything important. You wanted an exit button, you got an exit button. Should've been more specific in the requirements.
