//! Primal-dual perturbation handler — the shared implementation now lives in
//! [`pounce_common::pd_perturbation`].
//!
//! It moved there so the active-set QP (`pounce-qp`) can use the same tested
//! state machine. The dependency runs `pounce-algorithm -> pounce-qp`, so a
//! shared lower crate was the only way to reach it without duplicating 674
//! lines of IPOPT-ported logic. This module keeps the names other
//! `pounce-algorithm` code imports, and supplies the `PerturbationSink`
//! implementation over `IpoptDataHandle`.
