//! Phase-count and warning coverage for per-phase settings resolution.
//!
//! Responsibilities:
//! - Verify single-pass, two-phase, and three-phase mapping behavior.
//! - Assert warning flags for overrides that become unused under each mode.
//!
//! Not handled here:
//! - Override-precedence ordering.
//! - Invalid-model validation behavior.
//!
//! Invariants/assumptions:
//! - Single-pass execution resolves through Phase 2 settings.
//! - Warning flags precisely track which configured overrides were ignored.
