// What this crate lends `concinnity_core::behavior::BehaviorSystem`: the two
// things the system needs that only a host has.
//
//   save.rs   a state file under the host's save directory
//   eval.rs   the job pool a tick's evaluation fans out across
//
// The system itself, the VM it runs, and everything a tick does to the world
// are in concinnity-core; the gate in `ecs::schedule` builds it with both of
// these attached.
