//! Runtime / evaluation surface — IR-time and dispatch-time machinery.
//!
//! Audit cleanup A12 (2026-04-30): grouped from `vyre-foundation/src/`
//! root scatter so the layout scales beyond a flat 22-file root.
/// CPU-side `Op` trait + helpers for op-by-op evaluation.
/// CPU reference implementations of substrate primitives.
/// Compile-time IR evaluator (used by tests + const-fold spec checks).
/// Engine-wide match-result type (carries findings + telemetry).
/// Memory model: ordering, scope, and consistency rules.
/// Performance counter + telemetry surface.
/// Program-level capability bits surfaced from the runtime.
