What broke, dated. On 20 Aug 2026 this listing still called itself a single sheet and pitched a 30-minute guide that was really 33 pages. I rewrote both fields the same day to match what ships. The Copilot sheet you tape to the wall. Three pages. Page 1 is the habit: the loop you run when the answer matters, the prompt that works, and the one rule. Ground it, draft it, check it, decide. Page 2 is the harder question: eight boxes that tell you whether your organisation is ready for the people you are about to teach. Page 3 is what to do about your answer. It is not a course and it is not a feature tour. It is the order, on paper, where you can see it. It is the page I keep next to my own desk while deploying Copilot across an engineering company. Written by an independent practitioner, not a Microsoft employee, partner, or reseller. Download it, print page 1, and score page 2 honestly. Under six ticks, and the thing slowing your rollout is not prompting. Checked against Microsoft's own pages before publication. Since August 2026, three rival labs' models try to break every listing before I decide what ships. Misses, dated, with fixes: kesslernity.com/what-broke
