1//! Static analysis, normalization, and planning (Layers 4-5).
2//!
3//! Layer 4 starts here: the polarity-aware shape [`deps`]endency graph and
4//! [`strata`]ification analysis that realize the recursion semantics decided in
5//! `docs/03-recursion-semantics.md` (stratified; diagnose non-stratifiable).
6//! Normalization and logical→physical planning follow.
