nyash-codex b6e31cf8ca feat(joinir): Phase 184 - Body-local MIR Lowering Infrastructure
Phase 184 implements the foundation for body-local variable support in
update expressions, completing the three-box architecture:
LoopBodyLocalEnv (storage), UpdateEnv (composition), and
CarrierUpdateEmitter (emission).

## Implementation Summary

### Task 184-1: Design Document
- Created phase184-body-local-mir-lowering.md
- Two-Environment System design (ConditionEnv + LoopBodyLocalEnv)
- Box-First design principles documented

### Task 184-2: LoopBodyLocalEnv Implementation
- New file: src/mir/join_ir/lowering/loop_body_local_env.rs (216 lines)
- Storage box for body-local variable name → ValueId mappings
- BTreeMap for deterministic ordering (PHI consistency)
- 7 unit tests: empty env, single/multiple locals, get/contains, iteration

### Task 184-3: UpdateEnv Implementation
- New file: src/mir/join_ir/lowering/update_env.rs (237 lines)
- Composition box for unified variable resolution
- Priority order: ConditionEnv (condition vars) → LoopBodyLocalEnv (body-local)
- 8 unit tests: priority, fallback, not found, combined lookup

### Task 184-4: CarrierUpdateEmitter Integration
- Modified: src/mir/join_ir/lowering/carrier_update_emitter.rs
- Added emit_carrier_update_with_env() (UpdateEnv version)
- Kept emit_carrier_update() for backward compatibility
- 4 new unit tests: body-local variable, priority, not found, const update
- Total 10 tests PASS (6 existing + 4 new)

### Task 184-5: Representative Test Cases
- apps/tests/phase184_body_local_update.hako (Pattern1 baseline)
- apps/tests/phase184_body_local_with_break.hako (Pattern2, Phase 185 target)

### Task 184-6: Documentation Updates
- Updated: docs/development/current/main/joinir-architecture-overview.md
- Updated: CURRENT_TASK.md (Phase 184 completion record)

## Test Results

All 25 unit tests PASS:
- LoopBodyLocalEnv: 7 tests
- UpdateEnv: 8 tests
- CarrierUpdateEmitter: 10 tests (6 existing + 4 new)

Build:  Success (0 errors)

## Design Constraints

Following 箱理論 (Box Theory) principles:
- Single Responsibility: Each box has one clear purpose
- Deterministic: BTreeMap ensures consistent ordering
- Conservative: Pattern5 (Trim) integration deferred to Phase 185
- Fail-Fast: Explicit errors for unsupported patterns

## Scope Limitation

Phase 184 provides the **infrastructure only**:
-  Storage box (LoopBodyLocalEnv)
-  Composition box (UpdateEnv)
-  Emission support (CarrierUpdateEmitter)
-  Pattern2/4 integration (requires body-local collection, Phase 185)

## Next Steps

Phase 185: Pattern2/4 Integration
- Integrate LoopBodyLocalEnv into Pattern2/4 lowerers
- Add body-local variable collection from loop body AST
- Enable full E2E body-local variable support in update expressions

実行方法

これらのテストは主に tools/llvm_smoke.sh から実行されます:

# 環境変数でテストを有効化
NYASH_LLVM_MAP_SMOKE=1 ./tools/llvm_smoke.sh
NYASH_LLVM_VINVOKE_RET_SMOKE=1 ./tools/llvm_smoke.sh

注意事項

  • これらは最小限の機能テストであり、実用的なアプリケーションではありません
  • CIでの自動テストを前提に設計されています
  • エラー時の切り分けが容易になるよう、各テストは単一の機能に焦点を当てています
