//! Accuracy Validation Benchmarks
//!
//! This module provides comprehensive accuracy validation against scikit-learn
//! reference implementations, ensuring numerical correctness within specified tolerances.
//!
//! NOTE: This benchmark is currently a placeholder. Full implementation
//! requires completing the linear model API migration.
