//! Legacy `model=auto` wire types, kept for compatibility only.
//!
//! The types live in `lean_ctx_protocol` and are a frozen experimental surface
//! (`security/public-protocol-surface-freeze-v1.json`: not removed before the
//! next protocol major). The Engine re-exports them and does nothing with
//! them: the proxy never selects, ranks or substitutes a model or provider,
//! and holds no gate that would admit such a selection. The former
//! cost-improvement gate (`check_auto_eligibility`) is removed.
