//! In-memory property graph runtime.
//!
//! The graph crate owns node/edge storage, label sets, property maps, directed
//! adjacency, built-in label/property indexes, typed mutation validation, and
//! the CORE persistence provider. `SharedGraph` serializes writes through a
//! transaction boundary while readers observe immutable snapshots. selene-db is
//! a single native engine: the higher `selene-gql` layer owns GQL
//! binding/planning and the one frozen native procedure registry.
