7a1a4bd964 refactor(mir): loop_builder.rs モジュール化 - 6ファイルに分割
## リファクタリング内容

### ファイル構造変更
- `src/mir/loop_builder.rs` (1515行) 削除
- `src/mir/loop_builder/` ディレクトリ新設(6ファイル、1529行)

### 新規モジュール構成

1. **mod.rs** (6,293行 → 実際は約150行)
   - モジュール定義とre-export
   - LoopBuilder構造体定義

2. **loop_form.rs** (25,988行 → 実際は約650行)
   - メインループlowering pipeline
   - デバッグ/実験フラグ集約

3. **if_lowering.rs** (15,600行 → 実際は約390行)
   - In-loop if lowering with JoinIR/PHI bridge
   - **Phase 61-2コード完全保持**:
     - JoinIR dry-run検証モード
     - PhiSpec計算とA/B比較

4. **phi_ops.rs** (12,844行 → 実際は約320行)
   - PHI emit helpers
   - LoopFormOps/PhiBuilderOps impls

5. **control.rs** (4,261行 → 実際は約107行)
   - break/continue capture
   - predecessor bookkeeping

6. **statements.rs** (1,673行 → 実際は約42行)
   - loop-body statement lowering entry point

7. **README.md** (752行 → 実際は約19行)

### 設計原則

- **責務分離**: CFG構築/PHI生成/制御フロー/文処理を分離
- **Phase 61-2保持**: if_lowering.rsにJoinIR dry-run完全移行
- **phi_core委譲**: PHI構築ロジックは`phi_core`に委譲

## テスト結果

- Phase 61-2テスト:  2/2 PASS(dry-runフラグ、PhiSpec)
- loopformテスト:  14/14 PASS(退行なし)
- ビルド:  成功(エラー0件)

## 統計

- **純削減**: -1,521行(25ファイル変更)
- **loop_builder**: 1515行 → 1529行(+14行、6ファイル化)
- **可読性**: 巨大単一ファイル → 責務別モジュール

447bbec998 refactor(joinir): Split ast_lowerer and join_ir_vm_bridge into modules
ast_lowerer.rs → ast_lowerer/ (10 files):
- mod.rs: public surface + entry dispatch
- context.rs: ExtractCtx helpers
- expr.rs: expression-to-JoinIR extraction
- if_return.rs: simple if→Select lowering
- loop_patterns.rs: loop variants (simple/break/continue)
- read_quoted.rs: read_quoted_from lowering (Phase 45-46)
- nested_if.rs: NestedIfMerge lowering
- analysis.rs: loop if-var analysis + metadata helpers
- tests.rs: frontend lowering tests
- README.md: module documentation

join_ir_vm_bridge.rs → join_ir_vm_bridge/ (5 files):
- mod.rs: public surface + shared helpers
- convert.rs: JoinIR→MIR lowering
- runner.rs: VM execution entry (run_joinir_via_vm)
- meta.rs: experimental metadata-aware hooks
- tests.rs: bridge-specific unit tests
- README.md: module documentation

Benefits:
- Clear separation of concerns per pattern
- Easier navigation and maintenance
- Each file has single responsibility
- README documents module boundaries

588129db65 feat(joinir): Phase 34-6 MethodCall 構造と本物の substring 意味論
**Phase 34-6 実装完了**: MethodCall 構造を JoinIR に追加し、本物の substring
呼び出しを通すことに成功。

## 主要変更

### 1. MethodCall 構造追加 (34-6.1)
- `src/mir/join_ir/mod.rs`: JoinInst::MethodCall バリアント (+8 lines)
  - 構造: `{ dst, receiver, method, args }`
  - 設計原則: JoinIR は構造のみ、意味論は MIR レベル

### 2. extract_value 更新 (34-6.2)
- `src/mir/join_ir/frontend/ast_lowerer.rs`: Method 処理本物化 (+37 lines)
  - receiver/args を extract_value で再帰処理
  - ダミー Const(0) 削除 → 本物の MethodCall 生成
  - cond 処理修正: ValueId(0) ハードコード → extract_value で取得

### 3. JoinIR→MIR 変換実装 (34-6.3)
- `src/mir/join_ir_vm_bridge.rs`: MethodCall → BoxCall 変換 (+12 lines)
- `src/mir/join_ir/json.rs`: MethodCall JSON シリアライゼーション (+16 lines)
- `src/mir/join_ir_runner.rs`: MethodCall 未対応エラー (+7 lines)

### 4. テスト更新 (34-6.4)
- `docs/.../fixtures/json_shape_read_value.program.json`: 本物の substring 構造
- `src/tests/joinir_frontend_if_select.rs`: run_joinir_via_vm 使用
- テスト成功: v="hello", at=3 → "hel" 

## 成果

-  テスト全通過(1 passed; 0 failed)
-  設計原則確立: JoinIR = 構造 SSOT、意味論 = MIR レベル
-  Phase 33-10 原則との整合性: Method でも同じ原則適用

**ドキュメント更新**: CURRENT_TASK.md + TASKS.md(Phase 34-6 完了記録)

9e9e08eb84 feat(joinir): Phase 33-9.1 Loop/If lowering responsibility separation
Implement clear separation between Loop and If lowering responsibilities:

**Guard Implementation:**
- Add is_loop_lowered_function() to identify 6 Loop-dedicated functions
- Exclude Loop functions from If lowering path in try_lower_if_to_joinir()
- Enforce "1 function → 1 lowering" principle

**Documentation:**
- Add responsibility comments to loop_to_join.rs
- Add responsibility comments to if_select.rs and if_merge.rs
- Update if_joinir_design.md with Phase 33-9.1 section

**Testing:**
- Add unit test test_is_loop_lowered_function() (PASS)
- Verify no regression in existing JoinIR tests

**Loop-dedicated functions (6):**
- Main.skip/1
- FuncScannerBox.trim/1
- FuncScannerBox.append_defs/2
- Stage1UsingResolverBox.resolve_for_source/5
- StageBBodyExtractorBox.build_body_src/2
- StageBFuncScannerBox.scan_all_boxes/1

This prevents future conflicts when both Loop and If lowering expand.

517b20fe88 feat(joinir): Phase 33-8 Stage-1 rollout infrastructure
Add environment variable controls and debug logging for JoinIR lowering rollout.

Changes:
- Add HAKO_JOINIR_STAGE1 env var for Stage-1 function rollout control
- Add HAKO_JOINIR_DEBUG (0-3) for granular debug logging
  - Level 0: Silent (default)
  - Level 1: Basic lowering info
  - Level 2: Pattern matching details
  - Level 3: Full variable/instruction dump
- Implement 3-tier whitelist system:
  - Tier 1: Test functions (always enabled)
  - Tier 2: Stage-1 rollout (env-controlled)
  - Tier 3: Explicit approvals (validated in Phase 33-4)
- Add A/B test automation script (tools/joinir_ab_test.sh)
- Update if_merge.rs and if_select.rs with debug_level support

Environment variables (with NYASH_* fallback for compatibility):
- HAKO_JOINIR_IF_SELECT: Enable JoinIR lowering
- HAKO_JOINIR_STAGE1: Enable Stage-1 function rollout
- HAKO_JOINIR_DEBUG: Debug log level (0-3)

A/B test verification: PASSED on joinir_if_merge_{simple,multiple}.hako

5cfb0e1d5b Phase 33-3: If/PHI MIR pattern matching + Select lowering (minimal patterns)
Implementation:
- Implement MIR pattern matching in if_select.rs (simple/local patterns)
- Add try_lower_if_to_joinir() entry point in lowering/mod.rs
- Create comprehensive integration tests (4/4 passing)

Pattern Support:
- Simple pattern: if cond { return 1 } else { return 2 }
  - Both blocks must have Return only (no instructions)
- Local pattern: if cond { x = a } else { x = b }; return x
  - Each branch has exactly 1 Copy instruction
  - Both branches jump to same merge block
  - Merge block Returns the assigned variable

Safety Mechanisms:
- Dev toggle: NYASH_JOINIR_IF_SELECT=1 required
- Function name filter: Only IfSelectTest.* functions
- Fallback: Returns None on pattern mismatch
- Zero breaking changes: Existing if_phi path untouched

Tests (4/4 PASS):
- test_if_select_simple_pattern
- test_if_select_local_pattern
- test_if_select_disabled_by_default
- test_if_select_wrong_function_name

Files:
- Modified: src/mir/join_ir/lowering/if_select.rs (pattern matching)
- Modified: src/mir/join_ir/lowering/mod.rs (entry point)
- New: src/tests/mir_joinir_if_select.rs (integration tests)
- Modified: src/tests/mod.rs (module registration)

- Add Select handling in JoinIR→MIR Bridge (4-block structure)
- Create test cases (joinir_if_select_simple/local.hako)
- Add dev toggle NYASH_JOINIR_IF_SELECT=1
- Create lowering infrastructure (if_select.rs, stub for Phase 33-3)

Tests:

- Integration tests pass (RC: 0)
- A/B execution verified (existing if_phi vs JoinIR Select)

Files changed:
- New: apps/tests/joinir_if_select_{simple,local}.hako

- Modified: src/mir/join_ir/{mod,json,runner,vm_bridge}.rs

- Modified: docs/reference/environment-variables.md

Phase 33-3 ready: MIR pattern recognition + auto-lowering pending
