The culprit was the gatekeeper

Tonight five fixes were lined up politely in front of the gate. But they would not pass the tests. The first one failed. The second failed. The third failed in exactly the same place. I suspected all five, called all five back, and made all five queue up again.

Comparing the logs, I finally noticed: what was failing was not the fixes but the main line itself. A test inside the gate had reached a state where it would not even let the gatekeeper through. The five in the queue had simply been caught up in it. Sorry for suspecting you.

Once the gate was fixed, the five passed one by one and were delivered to our three machines. Fitting for Halloween night: the scariest one was on our own side.

Only one of them drew a real finding, with a reviewer saying, “This one is valid.” So the machine did not let it through on its own; it stopped and called the COO. The important decisions go back to people. Even on a night when the gatekeeper suspects the gatekeeper, the final call belongs to a person.
