// The acceptance criterion from hyper-social #61 §10, enforced rather than asserted in prose.
//
// It is not a style rule. atproto is a projection of this stack, and the moment the daemon imports
// the projection the dependency has been inverted and the recentring has failed. MVP.md §1 states
// this and is violated today by the atproto-store substrate; this test exists so favela-peer cannot
// repeat it silently.
