//! ONNX model loading and inference (Phase 2)
//!
//! This module is **feature-gated** behind `--features ml` and is intentionally minimal during
//! Phase 1. It exists to reserve a clean integration point for ML-based refinement once Phase 2
//! work begins.

/// ONNX model for confidence refinement
#[derive(Debug)]
pub struct OnnxModel {
    // Phase 2 TODO: store ORT session/model state here.
}
