Implements Phase 215 Task 215-2: Wire expr_result exit line through ExitMeta → JoinInlineBoundary → ExitLine → MIR return for Pattern 3. ## Changes ### Fix 1: JoinIR Lowerer (loop_with_if_phi_if_sum.rs:312) - Changed `carrier_only()` → `with_expr_result(sum_final, exit_meta)` - Marks sum final value as expr_result for propagation ### Fix 2: Boundary Builder (pattern3_with_if_phi.rs:176-191) - Added `.with_expr_result(Some(expr_id))` to JoinInlineBoundaryBuilder - Passes expr_result to boundary for ExitLineReconnector ### Fix 3: Final Return (pattern3_with_if_phi.rs:195-219) - Changed from always returning Void to conditional return: - Expr-position loops: Return merge_result ValueId - Statement-position loops: Return Void - Matches Pattern 2 behavior ## Test Results Primary target: - phase212_if_sum_min.hako: RC=2 achieved ✅ Regression tests: - loop_if_phi.hako: RC=2 (existing behavior maintained) ✅ - Pattern 1/2/3 tests: All PASS ✅ ## Architecture Pattern 3 now follows the same ExprResult Exit Contract as Pattern 2: 1. JoinIR lowerer creates expr_result with `with_expr_result()` 2. Boundary builder passes expr_result with `.with_expr_result()` 3. Conversion pipeline returns merge result containing exit PHI ValueId 4. Pattern dispatcher conditionally returns expr_result or Void This enables: - Expr-position loops: Loop result propagates to caller - Statement-position loops: Loop updates variable_map only (returns Void) - Unified contract: Patterns 2 and 3 follow same expr_result flow 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
