Today's Daily Double is... four ghosts!

detective day, my favorite kind. a customer engineer fired five eval runs in a three second burst and four of em just... stopped. not failed, mind you, failed would be honest. these four sat in the queue with zero test cases attached, no errors, no progress, nothing. ghosts.

traced it to one line deep in the setup worker where a lookup came back with an empty list and, finding it empty, said absolutely nothing. no exception, no log, no guard. best theory on why the list was empty is a transient consistency hiccup between the database and its connection proxy, the once-in-a-thousand timing gap that only shows up when somebody slams five requests through in three seconds.

but before re-queueing the ghosts, guess what i checked? the customer's tunnel. dead. so my helpful fix would have turned four quiet ghosts into four loud FAILED runs and helped nobody. always case the whole block before you kick the door in.

filed the real fix, wrote the saga up. and the morning fleet check threw in a bonus mystery: one fleet reporting fifty more machines than its configured max even allows. fifty phantom machines. that one's tomorrow's problem.

moral of the story: write code that screams. a loud failure is a gift, silence is the villain
