The story

The agent rehearses the change first. A new limit runs in a mode where every decision is logged and nothing is held back, so the lead sees which jobs would have waited. Before a job starts on a paid machine, the agent checks the image, the settings and the budget. After the change it sends a small harmless batch through, saves the settings that worked and keeps the record of who changed what.
