feat(joinir): Phase 188-Impl-3 Pattern 3 (Loop with If-Else PHI) implementation
Add Pattern 3 lowerer for `loop { if cond { x = a } else { x = b } ... }` pattern.
New files:
- loop_with_if_phi_minimal.rs (381 lines): JoinIR lowerer for Pattern 3
- Multiple loop variables (counter + accumulator)
- In-loop if/else PHI using Select instruction
- Carriers passed to next iteration via tail recursion
Modified files:
- join_ir/mod.rs: Add Mod to BinOpKind, Select to MirLikeInst
- loop_pattern_detection.rs: Add is_loop_with_conditional_phi_pattern() detection
- lowering/mod.rs: Pattern 3 router integration
- loop_patterns.rs: Pattern 3 entry point delegation
- json.rs: Mod/Select JSON serialization
- join_ir_ops.rs: Mod operation evaluation (a % b)
- join_ir_runner.rs: Select instruction execution
- join_ir_vm_bridge/convert.rs: Mod/Select conversion handlers
Implementation:
- Pattern 3 generates 3 JoinIR functions: main, loop_step(i, sum), k_exit(sum_final)
- Exit condition: !(i <= 5) with Jump to k_exit
- In-loop if/else: if (i % 2 == 1) { sum + i } else { sum + 0 }
- Select instruction: sum_new = Select(if_cond, sum_then, sum_else)
- Both carriers updated: Call(loop_step, [i_next, sum_new])
Build status: ✅ Compiles successfully (0 errors, 34 warnings)
Integration: Infrastructure complete, MIR boundary mapping pending
All 3 patterns now have lowering infrastructure in place for Phase 188.

feat(joinir): Phase 188 Pattern 1 Core Implementation + Phase 189 Planning
Phase 188 Status: Planning & Foundation Complete (100%)
Completed Tasks:
✅ Task 188-1: Error Inventory (5 patterns identified)
✅ Task 188-2: Pattern Classification (3 patterns selected)
✅ Task 188-3: Design (51KB comprehensive blueprint)
✅ Task 188-4: Implementation Foundation (1,802 lines scaffolding)
✅ Task 188-5: Verification & Documentation
✅ Pattern 1 Core Implementation: Detection + Lowering + Routing
Pattern 1 Implementation (322 lines):
- Pattern Detection: is_simple_while_pattern() in loop_pattern_detection.rs
- JoinIR Lowering: lower_simple_while_to_joinir() in simple_while_minimal.rs (219 lines)
- Generates 3 functions: entry, loop_step (tail-recursive), k_exit
- Implements condition negation: exit_cond = !(i < 3)
- Tail-recursive Call pattern with state propagation
- Routing: Added "main" to function routing list in control_flow.rs
- Build: ✅ SUCCESS (0 errors, 34 warnings)
Infrastructure Blocker Identified:
- merge_joinir_mir_blocks() only handles single-function JoinIR modules
- Pattern 1 generates 3 functions (entry + loop_step + k_exit)
- Current implementation only merges first function → loop body never executes
- Root cause: control_flow.rs line ~850 takes only .next() function
Phase 189 Planning Complete:
- Goal: Refactor merge_joinir_mir_blocks() for multi-function support
- Strategy: Sequential Merge (Option A) - merge all functions in call order
- Effort estimate: 5.5-7.5 hours
- Deliverables: README.md (16KB), current-analysis.md (15KB), QUICKSTART.md (5.8KB)
Files Modified/Created:
- src/mir/loop_pattern_detection.rs (+50 lines) - Pattern detection
- src/mir/join_ir/lowering/simple_while_minimal.rs (+219 lines) - Lowering
- src/mir/join_ir/lowering/loop_patterns.rs (+803 lines) - Foundation skeleton
- src/mir/join_ir/lowering/mod.rs (+2 lines) - Module registration
- src/mir/builder/control_flow.rs (+1 line) - Routing fix
- src/mir/builder/loop_frontend_binding.rs (+20 lines) - Binding updates
- tools/test_phase188_foundation.sh (executable) - Foundation verification
- CURRENT_TASK.md (updated) - Phase 188/189 status
Next: Phase 189 implementation (merge_joinir_mir_blocks refactor)
