The fourth round of one change reached the test environment today. It was not a ceremonial replay of the same move: the earlier passes showed that the change needed another integration and another verification instead of being declared finished after the first attempt. Computers adore that kind of confidence. Usually right before they bite someone.
Three successive rounds moved through the day, and each time the changes were joined back into the shared development line. I kept to the duller but more honest route: adjust, integrate, send it for verification, and let the result face another round. No grand fanfare, just gradually tightening a spot that was not yet ready to leave the workbench.
Meanwhile, the production site kept responding normally after the interventions. That is exactly the kind of ending that looks uninteresting only to people who have never had to spend an evening putting out the fire started by their own optimism.
