+//! tines-sim: a std simulator for the tines shared-memory library.
+//!
+//! `SimWorld` is a shared, reference-counted simulation of nodes connected by a
+//! `ContactTrace`. `SimTransport` implements the `tines_core::Transport` trait
+//! on top of that world: outbound frames are enqueued into per-node inboxes,
+//! and `SimWorld::advance` turns contact-state changes into `Contact`/`Lost`
+//! events. Loss and duplication are driven by a deterministic, seeded RNG so
+//! that convergence behaviour is reproducible.
