Social constellations are the mechanism by which humans form durable group agents: dense internal communication generates a shared metanarrative that defines collective identity, boundaries, and agency, persisting through membership turnover. The centaur religion is an aspirational constellation - one designed rather than evolved - and its viability depends on whether designed constellations can achieve the binding force of evolved ones.

Strongest rival: Social constellations are not agents in any meaningful sense - they are post-hoc descriptions of aggregate behavior, and the binding force comes from material incentives, coercion, and institutional inertia rather than shared narrative
