//! JoinIR integration for control flow
//!
//! This module contains JoinIR-related control flow logic:
//! - Pattern lowerers (patterns/)
//! - Routing logic (routing.rs) ✅
//! - Parity verification (parity_checker.rs) ✅ Phase 138
//! - Loop processing context (loop_context.rs) ✅ Phase 140-P5
//! - MIR block merging (merge/) ✅ Phase 4
//! - Unified tracing (trace.rs) ✅ Phase 195
//! - Control tree capability guard (control_tree_capability_guard.rs) ✅ Phase 112
