//! Phase 5b — active-set SQP algorithm driver.
//!
//! Sits parallel to [`crate::ipopt_alg::IpoptAlgorithm`]. Consumes
//! the same [`crate::ipopt_nlp::IpoptNlp`] for function /
//! derivative evaluations and reuses [`crate::line_search`] /
//! [`crate::conv_check`] machinery where it makes sense; the QP
//! subproblem solve is delegated to the `pounce-qp` crate
//! (Phases 5a, 5a.1, 5a.2 of the design note).
//!
//! Design reference:
//! [`docs/research/active-set-sqp-warm-start.md`].
//!
//! Selected via [`crate::alg_builder::AlgorithmChoice::ActiveSetSqp`].
//! The `InteriorPoint` choice (default) remains the
//! `IpoptAlgorithm` path with no changes.
