It's tempting to think a community succeeds if you simply pick good people. It doesn't. Every part of history's communes and co-ops shows the warm parts only survive when a few unglamorous things are handled first.
These six parts are the structure the warmth depends on. Each one answers a specific, well-documented way that good communities fall apart — by turning on their members, being quietly captured, seizing up, ageing out, hardening into a creed, exposing the vulnerable, or running out of money. None of it is bureaucracy for its own sake.
Read them in order, or jump to whatever matters most to you. They cross-reference one another, because they're really one connected design, not six separate essays.
These design principles were developed with AI, working from the ideas in the book and from established research and real-world models — then checked, shaped, and owned by the people who'll actually live them. The thinking is offered openly; the choices remain ours.
