このドキュメントは、JoinIR ライン全体Loop/If lowering, ExitLine, Boundary, 条件式 lowering
「箱」と「契約」を横串でまとめた設計図だよ。selfhost / JsonParser / hako_check など、
どの呼び出し元から見てもここを見れば「JoinIR 層の責務と流れ」が分かるようにしておく。
変更があったら、Phase ドキュメントではなく **このファイルを随時更新する** 方針。
---
## 1. 不変条件Invariants
JoinIR ラインで守るべきルールを先に書いておくよ:
1. **JoinIR 内部は JoinIR ValueId だけ**
- JoinIR lowering が発行する `JoinInst``ValueId` は、すべて `alloc_value()` で割り当てるローカル ID。
- Rust/MIR 側の ValueId`builder.variable_map` に入っている IDは、JoinIR には直接持ち込まない。
2. **host ↔ join の橋渡しは JoinInlineBoundary 系だけ**
- host から JoinIR への入力(ループ変数 / 条件専用変数)は
- `JoinInlineBoundary.join_inputs + host_inputs`
- `JoinInlineBoundary.condition_bindings`ConditionBinding
だけで接続する。
- 出力(キャリアの出口)は `JoinInlineBoundary.exit_bindings` に一本化する。

3. **LoopHeader PHI を SSA の単一源泉にする**
- ループ変数とキャリアは **LoopHeaderPhiBuilder/LoopHeaderPhiInfo** でヘッダ PHI を作り、これを「現在値」の SSOT にする。
- exit 用の PHI も組むが、変数再接続や expr_result 収集はヘッダ PHI を経由して行うSSAundef 防止)。
4. **式としての戻り値とキャリア更新を分離する**

7. **Param の役割ParamRoleを分ける**
- JoinIR 側で扱うパラメータは概念的に 3 種類に分かれる:
- 条件専用Condition param: 継続条件や break 条件だけに使う値
- キャリアCarrier param: ループ状態pos/result など)として更新される値
- 式結果Expr param: ループが式として返す値
- ExitLine / Header PHI / InstructionRewriter は **Carrier param だけ** を対象にし、Condition/Expr param は上書きしない。
- 現状は ConditionBinding/ExitMeta/JoinFragmentMeta で役割を区別しており、将来 ParamRole enum として明示する予定。
8. **LoopHeader PHI dst は予約領域(上書き禁止)**
- LoopHeaderPhiBuilder が生成したヘッダ PHI の dst ValueId は「現在のループ値」の SSOT として扱い、
BoundaryInjector や InstructionRewriter が `Copy` などで二度書きすることを禁止する。
- merge ラインでは「ヘッダ PHI dst に対する新しい定義が出てきたら debug モードで panic する」ことで契約違反を早期検出する。
9. **ParamRole の不変条件Phase 200-A 追加)**
- **Condition 役のパラメータは「PHI dst にしてはいけない」**
- 理由: 条件専用変数はループ内で更新されない(例: `digits` in `_atoi()`
- LoopHeaderPhiBuilder は Condition 役の変数に対して header PHI を生成しない
- **Condition 役のパラメータは「ExitLine の対象にも入れない」**
- 理由: 条件専用変数はループ外で使われない(ループ内でのみ参照)
- ExitLineReconnector は Condition 役の変数を exit_bindings から除外
- **ParamRole の分類**:
- `LoopParam`: ループ制御変数(例: `i` in `loop(i < len)`)→ header PHI + exit_bindings
- `Condition`: 条件専用変数(例: `digits` in `digits.indexOf(ch)`)→ condition_bindings のみ
- `Carrier`: 状態更新変数(例: `sum`, `count`)→ header PHI + exit_bindings
- `ExprResult`: ループ戻り値 → exit_phi_builder で処理
10. **JoinIR Core は常時 ON**
- LoopBuilder は物理削除済み。JoinIR を OFF にする経路やフォールバックは存在しない。
- `NYASH_JOINIR_CORE` は deprecated0 を指定しても警告して無視。JoinIR の OFF トグルは提供しない。
11. **Phase 220: P3 if-sum の ConditionEnv 統合完了**
- **LoopBuilder へのフォールバック経路は Phase 187 で完全削除済み**。
- **P3 if-sum には ConditionPatternBox + ConditionEnv が必須**:
- 単純条件(`var CmpOp literal`)のみ if-sum mode へルーティングPhase 219-fix
- 複雑条件(`i % 2 == 1` 等)は legacy P3 経路へフォールバック。
- **Phase 220-D で loop 条件の変数サポート完了**:
- `loop(i < len)` のような変数条件を ConditionEnv で解決。
- `extract_loop_condition()` を ValueOrLiteral 対応に拡張。
- **Phase 220 で if-sum の expr-result exit contract が P2 と揃った**:

## 1.9 ValueId Space Management (Phase 201)
JoinIR の ValueId 割り当ては **JoinValueSpace** で一元管理され、3つの領域に分離されているよ
### 1.9.1 ValueId 空間のダイアグラム
```
JoinValueSpace Memory Layout:
0 100 1000 u32::MAX
├──────────┼──────────┼──────────────────────────┤
│ PHI │ Param │ Local │
│ Reserved│ Region │ Region │
└──────────┴──────────┴──────────────────────────┘
PHI Reserved (0-99):
- LoopHeader PHI dst 用の予約領域
- reserve_phi(id) で特定 ID をマーク
Param Region (100-999):
- alloc_param() で割り当て
- 使用箇所: ConditionEnv, CarrierInfo.join_id, CapturedEnv
Local Region (1000+):
- alloc_local() で割り当て
- 使用箇所: Pattern lowerers (Const, BinOp, etc.)
```
### 1.9.2 JoinValueSpace の役割
- **単一の真実源 (SSOT)**: すべての JoinIR ValueId 割り当てを一箇所で管理
- **領域分離**: Param ID、Local ID、PHI dst が決して重複しない
- **契約検証**: デバッグモードで違反を早期検出
- **後方互換性**: 既存 API は継続動作
### 1.9.3 各コンポーネントと ValueId 領域の対応表
| コンポーネント | 使用領域 | 割り当て方法 | 用途 |
|--------------|---------|------------|------|
| ConditionEnv | Param (100-999) | `alloc_param()` | ループ条件変数の JoinIR ValueId |
| CarrierInfo.join_id | Param (100-999) | `alloc_param()` | キャリア変数の JoinIR ValueId |
| CapturedEnv | Param (100-999) | `alloc_param()` | 関数スコープ変数の JoinIR ValueId |
| Pattern 1 lowerer | Local (1000+) | `alloc_local()` | 中間値Const, Compare, etc. |
| Pattern 2 lowerer | Local (1000+) | `alloc_local()` | 中間値Const, BinOp, etc. |
| Pattern 3 lowerer | Local (1000+) | `alloc_local()` | 中間値PHI, Select, etc. |
| Pattern 4 lowerer | Local (1000+) | `alloc_local()` | 中間値Select, BinOp, etc. |
| LoopHeaderPhiBuilder | PHI Reserved (0-99) | `reserve_phi()` | PHI dst ID 保護(上書き防止) |
### 1.9.4 設計原則
1. **領域の固定境界**
- 明確な境界100, 1000で領域を分離
- デバッグが容易ValueId を見ればどの領域か一目瞭然)
- アロケータ間の調整不要
2. **reserve_phi() vs alloc_phi()**
- PHI dst ID は MirBuilderhost 側から来るため、JoinValueSpace は割り当てない
- `reserve_phi()` はマーカーのみ(「この ID を上書きするな」という契約)
3. **value_id_ranges.rs との関係**
- `value_id_ranges.rs`: **モジュールレベルの分離**min_loop, skip_ws 等の各モジュールに大きな固定範囲を割り当て)
- `JoinValueSpace`: **lowering 内部の分離**param vs local vs PHI
- 両者は相補的な役割
### 1.9.5 Phase 205: 領域契約の検証強化
**追加された Box-First 機能**:
1. **衝突検出debug-only**
- 全ての割り当てられた ValueId を追跡(`allocated_ids: HashSet<u32>`
- 重複割り当てを即座に検出し panicFail-Fast 原則)
- `check_collision()` で実装
2. **領域検証debug-only**
- `verify_region(id, expected_region)` で ValueId が期待される領域にいるか検証
- 違反時は明確なエラーメッセージと修正ヒントを提供
- 例: "ValueId(500) is in Param region, expected Local. Hint: Use alloc_local() for JoinIR values"
3. **RegionVerifier Box**
- 場所: `src/mir/builder/control_flow/joinir/merge/mod.rs::verify_valueid_regions()`
- 責務: merge 時に boundary と loop_info の ValueId 領域契約を検証
- 検証項目:
- 全ての `boundary.join_inputs` が Param 領域100-999にいる
- 全ての `condition_bindings[].join_value` が Param 領域にいる
- 全ての `carrier_phis[].phi_dst` が有効範囲(<= LOCAL_MAX
4. **明示的な領域定数**
```rust
pub const PHI_RESERVED_MIN: u32 = 0;
pub const PHI_RESERVED_MAX: u32 = 99;
pub const PARAM_MIN: u32 = 100;
pub const PARAM_MAX: u32 = 999;
pub const LOCAL_MIN: u32 = 1000;
pub const LOCAL_MAX: u32 = 100000;
```
**Fail-Fast 原則の実装**:
- 領域違反は即座に panicデバッグモード
- フォールバックやサイレント修正は一切行わない
- エラーメッセージに具体的な修正方法を含める

3. `merge_joinir_mir_blocks` が(マルチ関数対応):
- 全関数の BlockID を再割り当てblock_allocatorし、ValueId はパラメータを除外して収集。
- Boundary の condition/exit Bindings の JoinIR ValueId も remap 対象に追加。
- LoopHeader PHI を生成loop_header_phi_builderし、latch 側は instruction_rewriter が埋める。
- instruction_rewriter で関数をマージしつつ Call→Jump に変換、k_exit 関数はスキップ。
- BoundaryInjector で entry block に Copy を注入join_inputs + condition_bindings
- Header PHI を finalize → exit_phi_builder で expr_result/carrier の exit PHI を構築。
- ExitLineOrchestrator がヘッダ PHI dst を使って variable_map を更新。
- host の現在ブロックから JoinIR entry へ jump を張り、exit ブロックに切り替える。

## 4. JsonParser / Trim / P5 ループの現在地Phase 170181
### 4.1 JsonParser ループ空間と P1P5
Phase 181 で JsonParserBox 内の 11 ループを棚卸しした結果、
構造的には **すべて JoinIR Pattern14 (+ P5) で扱える** ことが分かったよ。
- 既に JoinIR 経路で動作しているもの:
- `_skip_whitespace`P2 + P5 Trim
- `_trim` leading/trailingP2 + P5 Trim
- **Phase 182 で P1/P2 パターン検証完了** ✅:
- Pattern1 (Simple): `_match_literal` 系ループで動作確認済みapps/tests/phase182_p1_match_literal.hako
- Pattern2 (Break): 整数演算ループで動作確認済みapps/tests/phase182_p2_break_integer.hako
- **ブロッカー発見**: 実際の JsonParser ループには 2 つの制約が必要:
1. LoopBodyLocal 変数の扱い(`ch`, `digit_pos`, `pos` など)
- 現状は Trim pattern 専用の carrier 昇格を試みてエラーになる
- P1/P2 では純粋なローカル変数(昇格不要)として扱うべき
2. 文字列連結フィルタPhase 178
- `num_str = num_str + ch` のような string concat を保守的に reject
- JsonParser では必須の操作なので段階的に有効化が必要
- **設計原則**:
- string は「特別扱いのパターン」ではなく、あくまで MirType の 1 種類として扱う。
- Pattern2/4 側で型名や変数名(`"result"`, `"num_str"` など)に依存した分岐は入れない。
- LoopUpdateAnalyzer の `UpdateKind` / `UpdateRhs` で「安全な更新パターン」を列挙し、
そのうち string にも適用可能なものだけを **ホワイトリストで許可**する。
- 実際の lowering は CarrierUpdateLowerer / 式 Lowerer 側で行い、JoinIR のループ形P1P4は増やさない。
3. 数値の桁展開Phase 190 設計完了)
- `v = v * 10 + digit` のような NumberAccumulation パターンを UpdateKind で whitelist 制御。
- 型制約: Integer のみ許可String は StringAppendChar 使用)。
- 検出: AST 構造解析名前依存禁止、Complex パターンは Fail-Fast で reject。

2025-12-08 23:14:10 +09:00
- **Phase 183 で LoopBodyLocal 役割分離完了** ✅:
- **設計**: LoopBodyLocal を 2 カテゴリに分類:
- **Condition LoopBodyLocal**: ループ条件header/break/continueで使用 → Trim 昇格対象
- **Body-only LoopBodyLocal**: ループ本体のみで使用 → 昇格不要、pure local 扱い
- **実装**: TrimLoopLowerer に `is_var_used_in_condition()` ヘルパー追加
- 条件で使われていない LoopBodyLocal は Trim 昇格スキップ
- 5 つの unit test で変数検出ロジックを検証
- **テスト**: `apps/tests/phase183_body_only_loopbodylocal.hako` で動作確認
- `[TrimLoopLowerer] No LoopBodyLocal detected` トレース出力で body-only 判定成功
- **次の課題→Phase 184 で対応)**: body-local 変数の MIR lowering 対応(`local temp` in loop body

- Phase 183 では "Trim promotion しない" 判定まで完了
- 実際の MIR 生成インフラは Phase 184 で実装済みPattern2/4 への統合は次フェーズ)
### 4.2 Body-local 変数の MIR lowering 基盤Phase 184
Phase 184 では、「条件には出てこない LoopBodyLocal 変数」を安全に JoinIR→MIR に落とすためのインフラ箱だけを追加したよ。
- **LoopBodyLocalEnv**
- 責務: ループ本体内で `local` 定義された変数の「JoinIR 側 ValueId のみ」を管理する。
- 入力: ループ本体 AST / JoinIR ビルダー。
- 出力: `name -> join_value_id` のマップ。
- 特徴: host 側との対応は持たない。ConditionEnv とは完全に分離された「本体専用ローカル環境」。
- **UpdateEnv**
- 責務: UpdateExpr lowering 時の変数解決順序をカプセル化する。
- 仕様: `ConditionEnv`(条件・キャリア)と `LoopBodyLocalEnv`(本体ローカル)を中で束ねて、
`resolve(name)` で「条件→ローカル」の順に ValueId を返す。
- 利用箇所: CarrierUpdateEmitter / CarrierUpdateLowerer が、変数名ベースで UpdateExpr を JoinIR に落とす時に利用。
- **CarrierUpdateEmitter 拡張**
- 責務: `LoopUpdateSummary`UpdateKindに応じて、int 系キャリア更新を JoinIR 命令に変換する。
- 変更点: 直接 `variable_map` を読むのではなく、`UpdateEnv` 経由で名前解決するように変更。
- 効果: 本体専用の LoopBodyLocal 変数(`temp`を、Pattern2/4 から安全に扱える土台が整った。
このフェーズではあくまで「ストレージ・名前解決・emit の箱」までで止めてあり、
Pattern2/4 への統合(実際に Body-local 更新を使うループを JoinIR 経路に載せるは次フェーズPhase 185 以降)の仕事として分離している。
- 構造的に P1P4 で対応可能(代表例):
- `_parse_number` / `_atoi`P2 Break- Phase 182 でブロッカー特定済み
- `_match_literal`P1 Simple while- Phase 182 で動作確認済み ✅
- `_parse_string` / `_parse_array` / `_parse_object`
P2 + P4 + P5 の組み合わせで表現可能なことを設計上確認済み)
- 低優先度だが理論上は P1P4 からの拡張で吸収可能:
- `_unescape_string` など、複雑な continue / 条件付き更新を含むループ
方針:
- **ループの「形」は P1P4 から増やさない**。
複雑さLoopBodyLocal 条件、OR chain、continue 多用など)は BoolExprLowerer /
ContinueBranchNormalizer / TrimLoopLowerer (P5) といった補助箱側で吸収する。
- JsonParser 側の P5 適用Trim / `_skip_whitespace` / `_parse_string` 最小版)は実証済み。
残りのループは Phase 17x18x で、P1P4+P5 の組み合わせとして段階的に実装していく。

## 6. RoadmapJoinIR の今後のゴール)
ここから先の JoinIR の「目指す形」を、箱レベルでざっくり書いておくよ。フェーズ詳細は各 phase ドキュメントに分散させて、このセクションは常に最新の方向性だけを保つ。
### 6.1 直近Phase 176-177 まわり)
- **P5Trim/JsonParser 系)ループの複数キャリア対応** ✅ Phase 176 完了 (2025-12-08)
- 完了内容:
- Pattern2 lowerer を全キャリア対応に拡張(ヘッダ PHI / ループ更新 / ExitLine
- CarrierUpdateLowerer ヘルパで UpdateExpr → JoinIR 変換を統一。
- 2キャリアpos + resultE2E テスト完全成功。
- 技術的成果:
- CarrierInfo / ExitMeta / ExitLine / LoopHeaderPhiBuilder の multi-carrier 対応を Pattern2 lowerer で完全活用。
- Trim pattern の「キャリア = ループ変数」という誤解を解消loop_var は特殊キャリア)。
- 次のステップ (Phase 177):
- JsonParser `_parse_string` 本体を P2+P5 で通すpos + result の 2 キャリアで実ループ動作確認)。
### 6.2 中期selfhost depth2 / JsonParser 本体)
- **JsonParserBox / Trim 系ループの本線化**
- 目標:
- `_trim` / `_skip_whitespace` / `_parse_string` / `_parse_array` などの主要ループが、すべて JoinIR Pattern14 + P5 で通ること。
- LoopConditionScopeBox + LoopBodyCarrierPromoter + TrimLoopHelper の上で安全に正規化できるループを広げていく。
- 方針:
- 「ループの形」は P1P4 から増やさず、複雑さは BoolExprLowerer / ContinueBranchNormalizer / P5 系の補助箱で吸収する。
- LoopPatternSpace の P6/P7/P12 候補break+continue 同時 / 複数キャリア条件更新 / early returnは、実アプリで必要になった順に小さく足す。
- **selfhost depth2.hako JoinIR/MIR Frontend**
- 目標:
- `.hako → JsonParserBox → Program/MIR JSON → MirAnalyzerBox/JoinIrAnalyzerBox → VM/LLVM` の深度 2 ループを、日常的に回せるようにする。
- Rust 側の JoinIR は「JSON を受け取って実行・検証するランナー層」、.hako 側が「JoinIR/MIR を構築・解析する言語側 SSOT」という役割分担に近づける。
- **Phase 230ExprLowerer / ScopeManager 設計フェーズ)**
- 目標: 条件式 / init 式 / carrier 更新式の lowering を将来ひとつの ExprLowerer + ScopeManager に統合できるよう、既存の散在する lowering/API/Env を設計レベルで整理する(このフェーズではコード変更なし)。
- **Phase 233loop_update_summary テスト刷新フェーズ)**
- 目標: deprecated `analyze_loop_updates()` 依存のテストを廃止し、`analyze_loop_updates_from_ast()` に揃えたユニットで if-sum 判定ラインの期待値を固定する。
- **Phase 232Failing Tests の棚卸しフェーズ)**
- 目標: `cargo test --release` で残っている 7 件の FAIL を「どの箱 / どのパターン / どのレイヤ」の問題かで整理し、P0/P1/P2 に分類して次フェーズのターゲットを決めるcore バグを見つけるフェーズではなく、未対応領域の可視化フェーズ)。
- **Phase 234ArrayFilter / Pattern3 設計フェーズ)**
- 目標: ArrayExtBox.filter 系 3 テストを P3 if-PHI の正式対象に含めるか、当面は PoC 領域として Fail-Fast を仕様として維持するかを docs ベースで決める(コード変更なし)。
- **Phase 235ExprLowerer / ScopeManager パイロット実装 & テスト)**
- 目標: ExprLowerer/ScopeManager の Condition 文脈を小さな範囲でユニットテストしつつ、Pattern2 の break 条件で validation-only の経路として動かし、既存の legacy lowering と挙動が一致することを確認する(本番 lowering の置き換えは後続フェーズ)。
- **Phase 236-EXExprLowerer / ScopeManager 本番導入 - Pattern2 break 条件)**
- 目標: Pattern2 の break 条件 lowering を ExprLowerer/ScopeManager 経由の本番経路に切り替え、既存の condition_to_joinir ベース実装と RC / JoinIR 構造 / ログ挙動が一致することを確認する(影響範囲は Pattern2 break 条件のみに限定)。
- **Phase 237-EXExprLowerer 条件パターン棚卸しフェーズ)**
- 目標: JsonParser / selfhost のループ条件・break/continue 条件をカタログ化し、ExprLowerer/ScopeManager で優先的に扱うパターンと後回しにするパターンを SSOT 化する(コード変更なし)。
- **Phase 238-EXExprLowerer / ScopeManager Scope Boundaries**
- 目標: ExprLowerer / ScopeManager / ConditionEnv / LoopBodyLocalEnv / UpdateEnv の責務と参照範囲を文書化し、「誰がどこまで見てよいか」を SSOT として固定する(コード変更なし、ガイドライン整備)。***

JoinIR は Rust 側だけでなく、将来的に .hako selfhost コンパイラ側でも生成・解析される予定だよ:
- .hako 側の JsonParser/分析箱は、Program JSON / MIR JSON v1 を読んで JoinIR/MIR を解析する。
- Rust 側 JoinIR ラインの設計変更(特に ValueId/ExitLine/Boundary 周り)は、
**必ずこのファイルを更新してから** .hako 側にも段階的に反映する方針。
「JoinIR の仕様」「箱の責務」「境界の契約」は、このファイルを SSOT として運用していく。

- ループパターンを闇雲に増やすこと
- P1P4構造 P5bodylocal 条件を昇格する補助パス)を「骨格」とみなし、
新しいパターンが必要になったときは LoopPatternSpace に追記してから、小さな箱で補う方針。
- LoopBuilder の復活や、JoinIR 以外の別ラインによるループ lowering
- LoopBuilder 系は Phase 186187 で完全に削除済み。
ループに関する新しい要件はすべて JoinIR 側のパターン/箱の拡張で扱う。
- JoinIR の中に言語固有のハードコード(特定 Box 名や変数名)を戻すこと
- Trim/JsonParser 系は、構造パターンと補助箱Promoter/Helperで扱い、
「sum」「ch」など名前ベースの判定は LoopUpdateSummary / TrimLoopHelper の内部に閉じ込める。
この Roadmap は、JoinIR 層の変更や selfhost 深度を進めるたびに更新していくよ。

- selfhost `.hako` コンパイラの全ループを JoinIR で処理 (Phase 210+)
docs(joinir): Phase 218 JsonParser if-sum investigation complete Completes Phase 218 investigation: Identifies root cause preventing AST-based if-sum lowerer from activating. ## Investigation Summary ### Test Case Created - File: apps/tests/phase218_json_if_sum_min.hako - Pattern: JsonParser-style conditional accumulation (sum = sum + i) - Expected: RC=10, Actual: RC=0 (blocked by phantom carrier) ### Root Cause Identified: Phantom Carrier Bug **Problem**: AST-based if-sum lowerer (Phase 213) never activates **Cause Chain**: 1. loop_update_summary.rs uses name-based heuristics 2. Detects phantom "count" variable (doesn't exist in code) 3. counter_count() returns 2 instead of 1 (i + phantom "count") 4. is_simple_if_sum_pattern() returns false 5. Dual-mode dispatch uses legacy fallback instead of AST lowerer **Evidence**: ``` Debug output shows hardcoded template "i % 2 == 1" (legacy lowerer) Not from AST extraction (AST-based lowerer never called) ``` ### Critical Discovery **Phase 216 claim "RC=2 ✅" for phase212_if_sum_min.hako is false** - Current execution: RC=0 (wrong) - Expected: RC=2 - Indicates: Phase 213-217 "success" was actually legacy lowerer ### Documentation Gap Phase 216/217 tests may not have been executed correctly, or regression occurred. All "if-sum" patterns are currently broken due to phantom carrier detection blocking AST lowerer activation. ## Files Created 1. apps/tests/phase218_json_if_sum_min.hako - Test case 2. docs/development/current/main/phase218-jsonparser-if-sum-min.md - Investigation report ## Files Updated 1. CURRENT_TASK.md - Phase 218 investigation results 2. joinir-architecture-overview.md - Phase 218 entry ## Next Steps: Phase 219 **Target**: Fix phantom carrier detection in loop_update_summary.rs **Fix**: Remove name-based heuristics, use assignment-based detection only **Expected Result**: Both phase212 and phase218 tests pass with correct RC ## Lessons Learned 1. Documentation can become stale - verify test results 2. Silent fallbacks hide bugs - dual-mode needs clear activation logging 3. Name heuristics are fragile - prefer structural analysis 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

## 3. JoinIR → JoinIR 正規化レイヤ(構想 / Phase 26-H ライン)
### 3.1 Structured JoinIR と Normalized JoinIR概念レベル
JoinIR ラインは、今後は「同じ JoinIR をフェーズごとに正規化していく」二段構成で扱う想定だよ:
- **Structured JoinIR現行層**
- Pattern15 / CarrierInfo / ConditionEnv / UpdateEnv / Boundary / ExitLine までを終えた状態。
- while/if/break/continue/return がまだ「構造」として残っていてよい層。
- いまの JoinIR loweringPattern lowerer 群)が出力しているものはここ。
- **Normalized JoinIRJoinIR / CPS 風層)**
- 制御構造をすべて「関数+継続+ Env」の形に正規化した状態。
- ループは `loop_step(env, k_exit)` と exit 継続のペア、if は `if_branch(env, k_then, k_else)` join 継続で表現。
- while/break/continue/return は **TailCallFn/TailCallKont + If** だけに還元され、goto/生の branch は現れない。
- Env は「ループキャリア + DigitPos/num_str などの Derived + captured 変数」を 1 つの struct としてまとめる。
パイプラインのイメージ:
```text
AST
JoinIR(Structured) // Pattern15, CarrierInfo, ConditionEnv/UpdateEnv, Boundary/ExitLine
↓ JoinIR パス A: 正規化JoinIR → JoinIR
JoinIR(Normalized) // 関数 + 継続 + Env のみTailCall-only
↓ JoinIR→MIR bridge
MIR
```
型レベルでは、次の二案のどちらかで扱う想定だよ(詳細は今後の Phase で選択):
- **案① 型を分ける**
- `JoinModuleRaw`Structured`JoinModuleCps`Normalizedを別型にする。
- BridgeJoinIR→MIR`JoinModuleCps` だけを受け取る。
- **案② 型は 1 つ+フェーズフラグ**
- `JoinModule { phase: JoinIrPhase, ... }` として、`phase = Structured / Normalized` をメタデータで持つ。
- JoinIR パスはすべて `fn run(&mut JoinModule)`= joinir→joinirで構成し、
Verifier が「phase=Normalized なら while/if/break/continue/return 禁止」などの不変条件をチェックする。
どちらの案でも本質は同じで、「JoinIR の下に JoinIR= 正規形フェーズ)を 1 段挟む」という設計、というのがポイントだよ。
### 3.2 Normalized JoinIR の基本モデル(ラフスケッチ)
Normalized JoinIR では、制御構造を次の 3 要素だけで表現する想定だよ:
- **Env環境**
- そのループ/if に必要な情報を 1 つにまとめた struct。
- フィールド種別の例:
- `Carrier`LoopState キャリア: i, sum, result, num_state 等)
- `Derived`DigitPos 二重値, NumberAccumulation 等)
- `Captured`(外側のローカルや関数パラメータ: s, len 等)
- **Fn通常の関数**
- 典型例: `loop_step(env, k_exit)` / `loop_body(env, k_exit)`
- 末尾は常に `TailCallFn` または `TailCallKont`
- **Kont継続**
- 典型例: ループ exit 後の処理、if 後の join、関数 return など。
- 末尾は別の Fn/Kont への tail-call。
制御の不変条件Normalized フェーズ):
1. 制御フローは `TailCallFn` / `TailCallKont` / `If(cond, then_k, else_k, env)` のみで表現する。
2. 各ループは「`loop_step(env, k_exit)` 関数 + `k_exit(env)` 継続」のペアとして現れるbreak は必ず k_exit へ TailCall
3. continue は `loop_step` への TailCall として現れる(ヘッダ PHI 相当は Env の書き込み順で表現)。
4. return は専用の `return_kont(env)` への TailCall で表現される。
5. EnvLayoutVerifier検証箱が、常に正しい EnvLayout が使われていることをチェックする。
これにより、現在 JoinIR 層で苦労している「PHI 配線」「exit_bindings/jump_args 整合性」「評価順のねじれ」は、
Normalized JoinIR 側では「Env フィールドの更新順」と「どの継続を呼ぶか」に還元される想定だよ。
### 3.3 Phase 26-H のフェーズ分割(案)
この正規化レイヤを一度に入れるのは重いので、Phase 26-H ラインとして小さく段階分けして進める方針だよ。
(番号は仮で、実際の Phase 番号は current の進行に合わせて調整する想定)
1. **Phase 26-H.A モデル定義と Doc 固定(コード変更最小)**
- JoinIR Architecture Overviewこのファイルに Structured / Normalized の二層構造を明文化(本節)。
- `JoinIrPhase` などのメタ情報だけを追加し、既存 lowering / Bridge の挙動は変えない。
- Normalized JoinIR の不変条件TailCall-only / EnvLayout 整合性)を Verifier の設計として書き出す。
2. **Phase 26-H.B 最小サブセットでの JoinIR→JoinIR パス導入**
- Pattern1単純 while, break/continue なし)だけを対象にした Normalized パスを実装。
- パイプライン:
- 既存: `JoinIR(Structured) → MIR`
- 新規: `JoinIR(Structured) → JoinIR(Normalized, small subset) → MIR`
- 新規パスは dev フラグの裏側で比較用にのみ使い、E2E で結果が一致することを確認(既定経路は従来のまま)。
3. **Phase 26-H.C Pattern24 / DigitPos / JsonParser への拡張**
- Pattern2/3/4 と DigitPos / NumberAccumulation / Trim を Normalized パスの対象に広げる。
- JsonParser `_parse_number` / `_atoi` を優先対象にし、JoinIR(Normalized) 経由での実行を dev フラグ付きで有効化。
- JoinIR(Structured) → JoinIR(Normalized) の各ステップに構造テストを追加し、「Env の更新」「継続の呼び出し順」が期待どおりかを固定。
4. **Phase 26-H.D Normalized JoinIR を canonical route に昇格**
- JoinIR→MIR Bridge が「Normalized フェーズの JoinIR だけ」を受け取るように変更。
- Structured JoinIR → MIR の直接パスは「比較テスト専用」として残すか、段階的に削除。
- selfhost / JsonParser / hako_check の代表ループはすべて Normalized JoinIR 経由で通ることを確認。
各サブフェーズでは「既存意味論を変えない」「Fail-Fast 原則を維持する」「新旧経路の比較テストを先に用意する」をガードとして運用するよ。
詳細な API/型設計は、Phase 26-H.A/B の中で `EnvLayoutBox` / `LoopStepSynthesizer` / `JpVerifier` 等の箱として段階的に固めていく想定。
### 3.4 Phase 27-CLEAN Pattern24 の軽量整理
- Pattern2〜4/loop_with_break_minimal まわりで可視性・ログ・補助関数を整理し、joinir_dev フラグ配下のデバッグログに寄せる。意味論は変えずに「読みやすさ」「追いやすさ」を優先するクリーンアップフェーズだよ。
