1//! Self-correcting simulation with adaptive time-stepping and conservation monitoring.
2//!
3//! This crate provides:
4//! - Conservation law monitoring (energy, momentum, angular momentum)
5//! - Adaptive time-stepping with PI controller
6//! - Shadow Hamiltonian tracking for symplectic integrators
7//! - Solver quality assessment and graceful degradation
8//! - Multi-rate integration (r-RESPA)
