refactor(phi_core): Phase 193 - Complete loopform modularization with 4-pass architecture
...
Phase 193: loopform_builder.rs modularization (1,166 → 102 lines, 91% reduction)
## Module Structure Created
```
src/mir/phi_core/loopform/
├── mod.rs (102 lines) - Public API coordinator
├── context.rs (148 lines) - ValueId management
├── variable_models.rs (101 lines) - Variable types
├── utils.rs (112 lines) - Utilities
├── exit_phi.rs (96 lines) - Exit PHI builder
├── builder_core.rs (411 lines) - Core builder logic
├── passes/
│ ├── mod.rs (67 lines) - Pass coordinator
│ ├── pass1_discovery.rs (156 lines) - Variable discovery
│ ├── pass2_preheader.rs (70 lines) - Preheader copies
│ ├── pass3_header_phi.rs (106 lines) - Header PHI construction
│ └── pass4_seal.rs (276 lines) - PHI completion
```
## 4-Pass Architecture Explicit
### Pass 1: Variable Discovery (pass1_discovery.rs)
- Classify variables as carriers or pinned
- Allocate all ValueIds upfront
- GUARD protection for invalid ValueIds
### Pass 2: Preheader Copy (pass2_preheader.rs)
- Emit deterministic copy instructions
- Order: pinned first, carriers second
### Pass 3: Header PHI Construction (pass3_header_phi.rs)
- Generate incomplete PHI nodes
- First input: preheader_copy (known)
- Second input: latch value (unknown)
### Pass 4: PHI Sealing (pass4_seal.rs)
- Complete PHI nodes with latch values
- Separate pinned/carrier handling
- PHI optimization (same-value detection)
## Size Comparison
Before:
- loopform_builder.rs: 1,166 lines (monolithic)
- loopform_passes.rs: 133 lines (documentation stub)
- Total: 1,299 lines in 2 files
After:
- 11 focused modules: 1,645 lines total
- Main file (mod.rs): 102 lines (91% reduction)
- Largest module: builder_core (411 lines)
- Average module size: 150 lines
- 4 pass modules: 608 lines (explicit structure)
## Success Criteria Met
✅ Directory structure created with 11 focused modules
✅ 4-pass architecture explicit and clear
✅ cargo build --release succeeds
✅ Loop programs execute correctly
✅ Zero breaking changes (all APIs compatible)
✅ Module documentation comprehensive
✅ All visibility correct (pub/pub(crate) appropriate)
## Files Modified
- NEW: src/mir/phi_core/loopform/mod.rs (public API)
- NEW: src/mir/phi_core/loopform/builder_core.rs (core builder)
- NEW: src/mir/phi_core/loopform/passes/*.rs (4 pass modules)
- MOVED: loopform_*.rs → loopform/*.rs (5 files)
- DELETED: loopform_builder.rs, loopform_passes.rs
- UPDATED: phi_core/mod.rs (import structure)
- UPDATED: json_v0_bridge/lowering/loop_.rs (import path)
## Impact
- **Maintainability**: Each pass has clear responsibilities
- **Testability**: Individual passes can be tested independently
- **Documentation**: Comprehensive module and pass documentation
- **Modularity**: Clean separation of concerns
- **Readability**: No file exceeds 411 lines
Phase 1-3 modularization complete. Ready for new feature development.

feat(mir): Phase 84-3 PhiTypeResolver for PHI+Copy graph type inference
...
- Add PhiTypeResolver box (ChatGPT Pro design) with DFS graph traversal
- Resolve types through PHI + Copy chains with safety conditions
- Case D reduced from 9 to 4 (56% reduction)
Implementation:
- src/mir/phi_core/phi_type_resolver.rs: New box with graph search
- src/mir/phi_core/mod.rs: Add module export
- src/mir/builder/lifecycle.rs: Integrate as P4 (before P3-C)
Algorithm:
- DFS traversal: root → Copy → src / Phi → inputs
- Collect base types (Const/Call/BoxCall/etc definitions)
- Safety: Return Some only when converges to 1 type
Test results:
- Baseline: 504 passed, 30 failed (was 494/33)
- Case D: 4 remaining (from 9, 56% reduction)
- Unit tests: 7/7 passed
Box responsibilities (final):
- GenericTypeResolver: P3-C (generic T/V inference)
- CopyTypePropagator: Copy alias only
- PhiTypeResolver: PHI + Copy graph traversal
Remaining 4 Case D: Special patterns (await/try-catch) need dedicated handling.
Phase 84 progress:
- Phase 84-1: Const type annotations (20→15→12)
- Phase 84-2: CopyTypePropagator (12→9, 25% reduction)
- Phase 84-3: PhiTypeResolver (9→4, 56% reduction)

feat(mir): Phase 69-3 Fix MIR non-determinism with BTreeSet
...
Replace HashSet with BTreeSet for CFG predecessors/successors:
- BasicBlock.predecessors: HashSet → BTreeSet
- BasicBlock.successors: HashSet → BTreeSet
- LoopFormOps.get_block_predecessors(): returns BTreeSet
- BasicBlock.dominates(): takes &[BTreeSet<BasicBlockId>]
This ensures deterministic PHI generation and test stability.
Test results:
- loop_with_continue_and_break tests: now deterministic (3/3 same output)
- loopform tests: 14/14 PASS (no regressions)
- merge_exit_with_classification tests: 3/3 PASS
Technical changes (6 files):
- basic_block.rs: BTreeSet types + new() initialization
- loopform_builder.rs: trait signature + 2 mock implementations
- phi_ops.rs: return type
- json_v0_bridge/loop_.rs: return type
Same pattern as Phase 25.1 (MirFunction.blocks HashMap → BTreeMap).

Changes:
- Delete src/mir/phi_core/phi_input_collector.rs (-384 lines)
- Inline PhiInputCollector logic in json_v0_bridge/lowering/loop_.rs
- sanitize: BTreeMap dedup + sort
- optimize_same_value: check all inputs for same value
- Remove mod declaration in phi_core/mod.rs
Rationale:
- PhiInputCollector already inlined in Phase 59 (loopform_builder.rs)
- Last remaining usage was in JSON v0 Bridge
- Simple inline preserves exact behavior
Impact:
- -384 lines (Box + tests)
- No behavior change (inline equivalent)
- Build & test pass ✅

refactor(phi): Phase 58 ConservativeMerge inline into merge_all_vars
...
Phase 58: ConservativeMerge 本体削除
## 変更内容
- ConservativeMerge::analyze を phi_merge.rs の merge_all_vars 内にインライン化
- conservative.rs から struct と impl を削除(約95行削減)
- conservative.rs はドキュメントコメントのみ残す
## 技術的詳細
- all_vars: 全ブランチの変数ユニオン(Conservative戦略)
- changed_vars: 実際に変更された変数(決定的順序のためBTreeSet使用)
- Conservative ∘ Elimination = Minimal SSA 理論コメント保持
## 削減効果
- conservative.rs: 149行 → 57行(92行削減、62%削減)
- ConservativeMerge struct 完全削除
- テストコード 35行削除
## テスト結果
- JoinIR: 56 passed / 0 failed
- PHI関連テスト: 全PASS

refactor(phi): Phase 57 PHI code reduction
...
## Changes
### 57-2-alt: Remove redundant ConservativeMerge call
- phi.rs called ConservativeMerge::analyze twice (once directly,
once via merge_all_vars)
- Now merge_all_vars returns changed_vars, eliminating redundancy
### 57-3: Delete PhiMergeOps trait (dead code, 17 lines)
- PhiMergeOps trait was defined but never called
- Only impl in loop_builder.rs was unused
- PhiBuilderOps has replaced it
### 57-4: Add responsibility comments to infer_type_from_phi
- Document that it's the "last resort" for type inference
- Specify deletion conditions (JoinIR type annotations)
## Cumulative PHI reduction
- Phase 38: 90 lines
- Phase 40-4.1: 35 lines
- Phase 41-1: 99 lines
- Phase 47: 33 lines
- Phase 57: 17 lines (PhiMergeOps) + optimization
- Total: 365+ lines removed

Phase 36-4: LoopSnapshotMergeBox reduction (470 → 363 lines, 22.8%)
- Removed dead code: merge_continue_for_header() + tests (~100 lines)
- Removed superseded helpers: optimize_same_value/sanitize_inputs + tests (~94 lines)
- Removed unused fields: header_phi_inputs/exit_phi_inputs + new/Default (~19 lines)
- Converted to pure static utility (no state, only static methods)

- Added responsibility markers to all public methods:
- Loop-only: set_if_context() (if-in-loop PHI context)
- Common: new(), generate_phis() (stable API for both If and Loop)
- If-only: generate_if_phis(), compute_modified_names_if(), get_conservative_if_values()
- Stub: generate_loop_phis() (Phase 37+ implementation target)
- No code changes (markers only)
LoopSnapshotMergeBox changes:
- Removed merge_continue_for_header(): NEVER CALLED in production
- Removed optimize_same_value(): superseded by PhiInputCollector::optimize_same_value()
- Removed sanitize_inputs(): superseded by PhiInputCollector::sanitize()
- Removed test_merge_continue_for_header_*: tests for dead method
- Removed test_optimize_same_value_*: tests for superseded method
- Removed test_sanitize_inputs_*: tests for superseded method
- Added 3 new tests for merge_exit_with_classification():

- test_merge_exit_with_classification_skips_body_local_internal(): Option C logic
- test_merge_exit_with_classification_break_only_loop(): Case B (header not in exit preds)
PhiBuilderBox changes:
- No wrapper created (hybrid usage pattern - only 1 Loop-specific method)
- Responsibility markers document Loop/If/Common method classification
- Usage pattern clarified: if-in-loop PHI vs loop PHI
Test results:
✅ cargo build --release: Clean build

cleanup(phi): Phase 27.4C Cleanup - ヘルパー統一・定数化・API縮小
...
Phase 1-2 完了: デバッグ・環境変数・対象関数の保守性向上
## Phase 1-1: デバッグフラグヘルパー化
**目的**: NYASH_LOOPFORM_DEBUG チェックの重複排除
**実装**:
- `is_loopform_debug_enabled()` 関数追加 (loopform_builder.rs:16-23)
- `#[inline]` + `pub(crate)` で効率的に共有
- 環境変数チェックを一元化
- 使用箇所 (5箇所 → 1箇所定義):
- loopform_builder.rs: seal_pinned_phis (line 367)
- loopform_builder.rs: seal_carrier_phis (line 431)
- loop_builder.rs: emit_header_phis 前 (line 315)
- loop_builder.rs: emit_header_phis 後 (line 324)
**効果**: 重複削減(5箇所 → 1箇所)、将来のログシステム変更が容易
## Phase 1-2: 対象関数名の定数化
**目的**: JoinIR Header φ バイパス対象関数の保守性向上
**実装**:
- `JOINIR_HEADER_BYPASS_TARGETS` 定数追加 (header_phi_builder.rs:52-59)
```rust
const JOINIR_HEADER_BYPASS_TARGETS: &[&str] = &[
"Main.skip/1",
"FuncScannerBox.trim/1",
];
```
- `is_joinir_header_bypass_target()` を定数ベースに変更 (line 61-66)
- `matches!()` → `.contains()` に変更
**効果**: 対象関数追加時の保守性向上、定数にドキュメント集約可能
## Phase 1-3: 環境変数チェック統一
**目的**: 環境変数チェックロジックの統一化
**実装**:
- `joinir_header_experiment_enabled()` を `env_flag_is_1()` 使用に変更
```rust
// Before
std::env::var("NYASH_JOINIR_HEADER_EXP").ok().as_deref() == Some("1")
// After
crate::mir::join_ir::env_flag_is_1("NYASH_JOINIR_HEADER_EXP")
```
- `HeaderPhiBuilder::new()` も同様に統一 (line 183)
**効果**: 環境変数チェックロジック統一、env_flag_is_1() の利点(キャッシュ等)を享受
## Phase 2: 不要 public 関数の整理
**目的**: API サーフェス縮小、保守性向上
**実装**:
- `joinir_header_experiment_enabled()` を削除
- 単一の呼び出し元 (`get_loop_bypass_flags()`) しかなかったためインライン化
- `get_loop_bypass_flags()` 内で直接 `env_flag_is_1()` を呼び出し (line 77-79)
```rust
let joinir_exp = crate::mir::join_ir::env_flag_is_1("NYASH_JOINIR_EXPERIMENT");
let header_exp = crate::mir::join_ir::env_flag_is_1("NYASH_JOINIR_HEADER_EXP");
```
**効果**: API サーフェス縮小、重複削減、保守コスト削減
## テスト結果
**コンパイル**: ✅ 0 errors, 19 warnings
**テスト**: ✅ 371 passed; 10 failed
- Phase 27.4C Refactor 時: 370 passed; 11 failed
- **+1 テスト通過!** 🎉
- 既存 failures 変化なし
## 修正ファイル
- src/mir/phi_core/loopform_builder.rs
- is_loopform_debug_enabled() 追加 + 使用
- src/mir/phi_core/header_phi_builder.rs
- JOINIR_HEADER_BYPASS_TARGETS 定数追加
- joinir_header_experiment_enabled() 削除(インライン化)
- get_loop_bypass_flags() 簡素化
- HeaderPhiBuilder::new() 統一化
- src/mir/loop_builder.rs
- is_loopform_debug_enabled() 使用 (2箇所)
## 総合効果
- ✅ 重複削減: 環境変数チェック 5箇所 → 1箇所
- ✅ 保守性向上: 対象関数追加が容易、ログシステム変更が容易
- ✅ API 縮小: 不要な内部関数削除
- ✅ テスト改善: +1 テスト通過
- ✅ 退行なし: 既存 failures 変化なし

refactor(phi): Phase 27.4C Refactor - seal_phis分割 + トグル条件一元化
...
推奨アクション 1 & 2 実装完了
## Action 1: seal_phis メソッド分割
**目的**: 150行超の seal_phis を責任ごとに分割、可読性・保守性向上
**実装**:
- seal_pinned_phis() 追加 (loopform_builder.rs:347-407)
- Pinned 変数専用 φ seal 処理を抽出
- Header φ バイパス時の early return 含む
- seal_carrier_phis() 追加 (loopform_builder.rs:409-477)
- Carrier 変数専用 φ seal 処理を抽出
- Header φ バイパス時の early return 含む
- seal_phis() を委譲パターンに簡素化 (loopform_builder.rs:340-342)
**効果**:
- メソッド長: 150行 → 3行(委譲) + 60行(Pinned) + 68行(Carrier)
- 責任の明確化: Pinned/Carrier 処理が独立
- 将来の拡張が容易(Exit φ バイパス追加時など)
## Action 2: トグル条件ヘルパー一元化
**目的**: Header φ バイパス条件判定の重複排除、保守性向上
**実装**:
- LoopBypassFlags 構造体追加 (header_phi_builder.rs:18-24)
- header/exit バイパスフラグを統合管理
- get_loop_bypass_flags() 関数追加 (header_phi_builder.rs:26-38)
- 関数名からバイパスフラグを一元計算
- NYASH_JOINIR_EXPERIMENT/HEADER_EXP チェック
- Main.skip/1 & FuncScannerBox.trim/1 判定
- loop_builder.rs で 2箇所から呼び出し (lines 299-307, 609-612)
- fn_name を String として取得 (loop_builder.rs:299-304)
- 借用問題回避(&str → String)
**効果**:
- 重複削減: 3箇所 → 1箇所の定義
- バグ防止: 条件判定ロジックの不一致を防止
- 借用問題解決: fn_name String 化で Rust 借用チェッカー通過
- 将来対応: Exit φ バイパス(Phase 27.6-2)追加が容易

feat(mir): Phase 26-H JoinIR型定義実装完了 - ChatGPT設計
...
## 実装内容(Step 1-3 完全達成)
### Step 1: src/mir/join_ir.rs 型定義追加
- **JoinFuncId / JoinContId**: 関数・継続ID型
- **JoinFunction**: 関数(引数 = φノード)
- **JoinInst**: Call/Jump/Ret/Compute 最小命令セット
- **MirLikeInst**: 算術・比較命令ラッパー
- **JoinModule**: 複数関数保持コンテナ
- **単体テスト**: 型サニティチェック追加
### Step 2: テストケース追加
- **apps/tests/joinir_min_loop.hako**: 最小ループ+breakカナリア
- **src/tests/mir_joinir_min.rs**: 手書きJoinIR構築テスト
- MIR → JoinIR手動構築で型妥当性確認
- #[ignore] で手動実行専用化
- NYASH_JOINIR_EXPERIMENT=1 トグル制御
### Step 3: 環境変数トグル実装
- **NYASH_JOINIR_EXPERIMENT=1**: 実験モード有効化
- **デフォルト挙動**: 既存MIR/LoopForm経路のみ(破壊的変更なし)
- **トグルON時**: JoinIR手書き構築テスト実行
## Phase 26-H スコープ遵守
✅ 型定義のみ(変換ロジックは未実装)
✅ 最小限の命令セット
✅ Debug 出力で妥当性確認
✅ 既存パイプライン無影響
## テスト結果
```
$ NYASH_JOINIR_EXPERIMENT=1 cargo test --release mir_joinir_min_manual_construction -- --ignored --nocapture
[joinir/min] MIR module compiled, 3 functions
[joinir/min] JoinIR module constructed:
[joinir/min] ✅ JoinIR型定義は妥当(Phase 26-H)
test result: ok. 1 passed; 0 failed
```
## JoinIR理論の実証
- **φノード = 関数引数**: `fn loop_step(i, k_exit)`
- **merge = join関数**: 分岐後の合流点
- **ループ = 再帰関数**: `loop_step` 自己呼び出し
- **break = 継続呼び出し**: `k_exit(i)`
## 次フェーズ (Phase 27.x)
- LoopForm v2 → JoinIR 自動変換実装
- break/continue ハンドリング
- Exit PHI の JoinIR 引数化

feat(phi): Phase 26-F-4 - LoopExitLivenessBox実装完了(環境変数ガード付き)
...
4箱構成による責務分離完成 + 段階的実装戦略
# 実装内容
## 1. LoopExitLivenessBox新設 (loop_exit_liveness.rs)
- Exit後で実際に使われる変数の決定専門箱
- Phase 1: 空のlive_at_exit返却(MIRスキャン実装待ち)
- 環境変数制御:
- デフォルト: Phase 26-F-3相当の挙動
- NYASH_EXIT_LIVE_ENABLE=1: 将来のMIRスキャン実装を有効化(実験用)
- デバッグトレース: NYASH_EXIT_LIVENESS_TRACE=1
## 2. BodyLocalPhiBuilder拡張 (body_local_phi_builder.rs)

1. LoopVarClassBox - スコープ分類(Pinned/Carrier/BodyLocal*)
2. LoopExitLivenessBox - Exit後の実際の使用(新設)
3. BodyLocalPhiBuilder - 統合判定(OR論理)
4. PhiInvariantsBox - Fail-Fast検証
# テスト結果
- Phase 26-F-3: 358 PASS / 13 FAIL
- Phase 26-F-4 (デフォルト): 365 PASS / 9 FAIL ✅
- +7 PASS、-4 FAIL(大幅改善)
- Phase 26-F-4 (NYASH_EXIT_LIVE_ENABLE=1): 362 PASS / 12 FAIL

feat(phi): Phase 26-F-3 - ループ内if-merge PHI生成対応完了
...
## 成果
- テスト結果: 354→360 PASS (+6), 14→11 FAIL (-3)
- 退行なし、純粋な改善 ✨
## ChatGPT設計: 箱離婚 + 最小限の橋
### 問題
ループ内if-breakパターンで片腕のみの変数がPHI未生成
```hako
loop(i < n) {
if i >= n { break } // then腕: i なし(break)
i = i + 1 // else腕: i あり → PHI必要だがスキップされる
}
```
### 解決: 3箱の責務分離設計
**IfPhiContext(橋渡し箱)**
- in_loop_body: bool
- loop_carrier_names: BTreeSet<String>
**IfBodyLocalMergeBox(If側)**
- ループを知らない(箱離婚)
- carrier変数は片腕のみでもPHI候補に
- 通常if: 両腕に存在する変数のみ
**LoopBuilder(Loop側)**
- pre_if_var_mapからcarrier_names抽出
- IfPhiContext経由で橋渡し
## 修正ファイル
- src/mir/phi_core/phi_builder_box.rs: IfPhiContext拡張
- src/mir/phi_core/if_body_local_merge.rs: ループ内モード実装
- src/mir/loop_builder.rs: carrier_names設定
## テスト追加
- test_loop_internal_if_break_carrier_variable: ループ内if-break
- test_loop_internal_non_carrier_still_filtered: 非carrier除外

**既知の問題**:
- domination error依然残存(%48 in bb48 from bb52)
- 次フェーズで調査・修正予定
技術詳細:
- ChatGPT箱理論分析による設計
- A案ベースのシンプル実装
- 責務明確化: ループスコープ分析 vs if-merge専用処理

feat(phi): Phase 26-E-3 - PhiBuilderOps委譲実装(has-a設計)
...
Phase 26-E Phase 3 完了: ChatGPT+Claude 合意による委譲設計実装
**設計合意 (ChatGPT + Claude consensus):**
- PhiBuilderOps = 低レベル「PHI命令発行」道具箱
- LoopFormOps = 高レベル「ループ構造構築」作業場
- 関係: has-a(委譲) ではなく is-a(継承)
- LoopBuilder は両方のインターフェースを個別実装で提供
**実装内容:**
1. LoopFormOps trait 設計コメント更新
- 継承ではなく委譲の設計rationale明記
- 段階的統合方針: If側→Loop側→将来統合
2. LoopBuilder に PhiBuilderOps 委譲実装 (64行)
- 委譲パターン: LoopFormOps 既存実装を再利用
- HashSet → Vec 変換 + ソート(決定性保証)
- emit_phi: block 引数差を吸収(current_block 設定)
- 自己呼び出し回避: <Self as LoopFormOps>::method 明示
**技術的成果:**
- 重複コードゼロ: 既存 LoopFormOps 実装に完全委譲
- 決定性保証: pred_vec.sort_by_key(|bb| bb.0) で決定的順序
- シグネチャ差分吸収: PhiBuilderOps/LoopFormOps の違いを吸収
- 破壊的変更なし: 既存コード保護
**委譲実装の利点:**
1. 抽象化レベル分離: 低レベル(PHI発行)と高レベル(ループ構築)
2. 既存コード保護: LoopFormOps 実装は変更なし
3. 段階的統合: If側から先に PhiBuilderOps 安定化
4. テスト容易性: PhiBuilderOps/LoopFormOps それぞれでテスト可能
