1//! Primal-dual perturbation handler — the shared implementation now lives in
2//! [`pounce_common::pd_perturbation`].
3//!
4//! It moved there so the active-set QP (`pounce-qp`) can use the same tested
5//! state machine. The dependency runs `pounce-algorithm -> pounce-qp`, so a
6//! shared lower crate was the only way to reach it without duplicating 674
7//! lines of IPOPT-ported logic. This module keeps the names other
8//! `pounce-algorithm` code imports, and supplies the `PerturbationSink`
9//! implementation over `IpoptDataHandle`.
