//! Phase-0 benchmark: dense LU solve on an assembled Jacobian.

//!
|
|
//! The Jacobian is taken from the deterministic mock refrigeration cycle so the
|
|
//! benchmark is independent of the heavy CoolProp backend and measures only the
|
|
//! linear algebra path used by the Newton solver (Ruiz equilibration + LU).
