+//! ## Status (Phase 179)
+//!
+//! **TODO: Consider removal or unification** - This module appears unused (all tests commented).
+//! Cannot easily merge with `condition_lowerer.rs` because:
+//! - This module: MIR-based (uses MirBuilder, stateful)
+//! - condition_lowerer: JoinIR-based (pure functional, no builder)
+//!
+//! Decision: Keep separate for now, document the distinction clearly.
