The prompt
Minesaka Railway is a private railway company in Japan. Its main line is profitable, but a 40 km rural branch line loses money every year as the valley's population ages and shrinks. The CEO asks whether to close the branch line and replace it with buses. The partner says: "What would you tell the CEO, and how would you handle the prefecture?"
Partner-led: a judgment case with public-interest issues. A little math anchors the answer; most of the time goes on stakeholders and pushback.
