//! nox โ proof-native virtual machine over the Goldilocks field
//!
//! Sixteen deterministic reduction patterns (Layer 1), one non-deterministic
//! hint pattern (Layer 2), five jets for efficient recursive STARK
//! verification (Layer 3).

//! # Module structure
//!
//! ```text
//! noun โ Atom, Cell, Noun (binary tree of field elements)
//! reduce โ Layer 1 reduction engine (16 patterns)
//! hint โ Layer 2 non-deterministic witness injection
//! jet โ Layer 3 jets (hash, poly_eval, merkle_verify, fri_fold, ntt)
//! trace โ execution trace recording (becomes the STARK witness)
//! encode โ canonical noun serialization (deterministic wire format)
//! memo โ content-addressed computation cache
//! focus โ resource metering (attention budget)
//! ```
