//! Phase 2 binding plane — ephemeral `Scope` model.
//!
//! This module hosts the runtime scope arena and (in P2U11) the content-
//! addressed `ScopeStableId` + `ScopeProvenance` + `ScopeProvenanceStore`
//! persistence layer. Later units (P2U03) will add `derive.rs` for the
//! scope-derivation walk and `tree.rs` for the scope chain helpers.
