//! Model-default and effort-handling coverage for per-phase settings resolution.
//!
//! Responsibilities:
//! - Verify runner-specific model defaulting behavior.
//! - Assert reasoning-effort handling for Codex and non-Codex phases.
//!
//! Not handled here:
//! - Override-precedence ordering.
//! - Execution-mode warning coverage.
//!
//! Invariants/assumptions:
//! - Runner changes without explicit models must fall back to that runner's default model.
//! - Non-Codex phases ignore reasoning-effort inputs.
