These twenty-seven ended in a rule for whoever operates the fleet next, human or agent, because the mistake was not about a device at all. The first twenty-one were collected on 20260920 out of the six lesson themes; rules 22 to 27 were added on 20260922 from Christoph&rsquo;s read of these pages, each from the lesson it cites. All were checked against the runbook that carries the fleet&rsquo;s operating traps to confirm none of them was already written there, and added to it as a dated section. Each is stated as the instruction an operator is expected to follow, with the lesson it came from.</p>
