### E. Legacy Loop/PHI 経路の囲い込みと削除準備
- E-1: Legacy loop_phi.rs の役割と削除条件の明文化
- ファイル: `src/mir/phi_core/loop_phi.rs`
- 状態: LoopForm v2 + LoopSnapshotMergeBox への移行後は「legacy scaffold」としてのみ残存。
- やること:
- 現在の利用箇所を 2 種類に分類する:
- 本線経路（LoopForm v2 / Stage‑1 / Stage‑B から参照される部分）
- 互換レイヤ／解析専用（JSON v0 bridge, 旧 smokes, dev-only ヘルパ）
- 本線はすべて `loopform_builder.rs` + `header_phi_builder.rs` + `loop_snapshot_merge.rs` で賄えることを確認し、`loop_phi.rs` を「legacy 専用（新規利用禁止）」として CURRENT_TASK と docs に固定しておく。
- Phase 31.x の cleanup で実ファイル削除してよい条件（参照 0＋対応する smokes/テストの移行完了）を `docs/private/roadmap/phases/phase-31.2/legacy-loop-deletion-plan.md` 側と揃えておく。
- E-2: PHI/LoopForm 周辺で HashMap を使ってよい／いけない場所を線引き
- ファイル: `src/mir/builder.rs`, `src/mir/phi_core/*`, `src/mir/loop_builder.rs`
- やること:
- 「PHI 生成とスナップショット決定」に関わる構造では `BTreeMap` / `BTreeSet` / `Vec+sort` のみに限定し、`HashMap` は使わない、というルールを Phase 25.1 docs に明記する。
- それ以外のメタ情報（plugin sigs, weak_fields など）は HashMap 維持可とし、「決定性」に影響しないことをコメントで示しておく。
- 代表として `loop_phi.rs` 内の `sanitize_phi_inputs` のように「一度 HashMap で集約してから sort する」パターンは、LoopForm v2 正系統では `PhiInputCollector` + BTree 系で代替されていることを確認し、legacy 側のみに閉じ込める。
- E-3: Legacy 経路の一覧と新規利用禁止ポリシーを docs に反映
- ファイル:
- `docs/development/roadmap/phases/phase-25.1/README.md`（本線側のルール）
- `docs/private/roadmap/phases/phase-31.2/legacy-loop-deletion-plan.md`（削除計画側と整合させる）
- やること:
- Legacy として扱うモジュール（例: `phi_core::loop_phi`, 一部旧 JSON v0 bridge helper）を一覧にして、「新しいコードからここを呼ばない」「Phase 31.x で削除予定」と明記する。
- 逆に、今後 PHI/Loop/If で使うべき SSOT 箱（LoopForm v2 + HeaderPhiBuilder + BodyLocalPhiBuilder + if_phi + ControlForm）を 1 セクションで列挙し、「ここだけを見ると設計が分かる」導線を作る。
## 3. Phase 25.1q — LoopForm Front Unification（DONE / follow-up 別タスクへ） ## 3. Phase 25.1q — LoopForm Front Unification（DONE / follow-up 別タスクへ）
- 目的: Rust AST ルート (LoopBuilder) と JSON v0 ルート (`json_v0_bridge::lower_loop_stmt`) のループ lowering を “LoopFormBuilder + LoopSnapshotMergeBox” に一本化し、どの経路からでも同じ SSOT を見るだけで良い構造に揃える。 - 目的: Rust AST ルート (LoopBuilder) と JSON v0 ルート (`json_v0_bridge::lower_loop_stmt`) のループ lowering を “LoopFormBuilder + LoopSnapshotMergeBox” に一本化し、どの経路からでも同じ SSOT を見るだけで良い構造に揃える。

## Legacy Loop/PHI 経路と削除方針（Phase 25.1 時点の整理）
### 正系統（SSOT）として見るべき箱
- ループまわりの SSOT:
- `src/mir/loop_builder.rs` … LoopForm v2 の構造的 lowering（header/body/latch/continue_merge/exit）。
- `src/mir/phi_core/header_phi_builder.rs` … header PHI（Pinned/Carrier）の宣言と seal 用メタデータ。
- `src/mir/phi_core/loop_snapshot_manager.rs` … continue/exit スナップショット管理と LoopSnapshotMerge への導線。
- `src/mir/phi_core/loop_snapshot_merge.rs` … preheader + continue_merge + latch + exit の snapshot を LoopForm 単位でマージする箱。
- if/merge まわりの SSOT:
- `src/mir/builder/if_form.rs` … IfForm を用いた構造化 if lowering。
- `src/mir/phi_core/if_phi.rs` … if merge ブロックでの PHI 生成（ControlForm ベースのラッパを含む）。
- 今後: `BodyLocalPhiBuilder` を if-merge 側にも拡張して、BodyLocal 変数の PHI 判定を exit だけでなく body 内 if にも適用する予定（Phase 25.x/26.x で対応）。
### Legacy 経路（新規利用禁止・将来削除予定）
- `src/mir/phi_core/loop_phi.rs`
- 冒頭コメントどおり、LoopForm v2 + LoopSnapshotMergeBox への移行後は「legacy scaffold」としてのみ残存している。
- 現在の役割:
- 一部の dev/分析用ドキュメントや smokes から参照される互換レイヤ。
- 旧 LoopBuilder 互換 API（`prepare_loop_variables_with`, `seal_incomplete_phis_with`, `build_exit_phis_with` など）の受け皿。
- Phase 25.1 のポリシー:
- **新しいコードから `phi_core::loop_phi` を直接呼ばない**（LoopForm v2 系の箱のみを使う）。
- Legacy テスト／smoke のためにしばらく残すが、本線の PHI/SSA 設計の説明は LoopForm v2 系のファイルに寄せる。
- 削除条件（Phase 31.x 以降で実施予定）:
- すべての本線経路が `loopform_builder.rs` + `header_phi_builder.rs` + `loop_snapshot_merge.rs` に移行済みであること。
- `loop_phi.rs` を参照するのが「docs／analysis／legacy-smoke」のみになっていること。
- `docs/private/roadmap/phases/phase-31.2/legacy-loop-deletion-plan.md` に記載の条件（参照 0＋対応テスト移行）が満たされた時点で削除。
### HashMap 利用の線引き（決定性の観点）
- Phase 25.1 以降、**PHI／LoopForm／IfForm の決定性に関わるマップ**は次のルールに従う:
- 変数スナップショットや PHI 入力候補のように「順序が意味を持つ」構造:
- `BTreeMap` / `BTreeSet` / `Vec + sort_by_key` のいずれかを使用して、イテレーション順を決定的にする。
- 例:
- `MirBuilder::variable_map` / `value_types` / `value_origin_newbox` → `BTreeMap` 化済み。
- `phi_core::if_phi::compute_modified_names` → `BTreeSet` で変数名を収集したうえで決定的順序でマージ。
- メタ情報やインデックス（型とは無関係なキャッシュ・診断用データ構造など）:
- HashMap 維持可とし、「決定性には影響しない」ことをコメントで明記する。
- 例:
- `MirBuilder::weak_fields_by_box`, `property_getters_by_box`, `plugin_method_sigs` など。
- 例外: `phi_core::loop_phi::sanitize_phi_inputs`
- 現在も内部で一度 `HashMap<BasicBlockId, ValueId>` に詰め替えた後 `Vec` に戻して `sort_by_key` しているため、出力順自体は決定的になっている。
- ただし、このユーティリティは **legacy 経路専用** と位置付けており、新しい LoopForm v2 系のコードでは `PhiInputCollector`（BTree ベース）側を SSOT として扱う。

/*! /*!
* Phase 25.1 StaticCompiler receiver型推論バグ回帰防止テスト * Phase 25.1 StaticCompiler receiver型推論バグ回帰防止テスト（最小箱版）
* *
* ## 問題再現 * 元のバグ:
* - StringHelpers.skip_ws/2 呼び出しで receiver 型情報なし * - StringHelpers.skip_ws/2 呼び出し内部で receiver 型情報が欠落し、
* - ParserBox.length が Global("ParserBox.length") に変換されてVM落ち * `.length()` が ParserBox.length など誤った Box として解決されて VM 落ち。
* *
* ## 修正内容 * Rust 側の修正:
* - Phase 1: guard.rs でreceiver型なし→Global変換 * - Phase 1: guard.rs で receiver 型なし→ Global 変換（捏造 ValueId 防止）
* - Phase 2: unified_emitter.rs で guard→materialization 順序反転 * - Phase 2: unified_emitter.rs で guard→materialization の順序反転
* - Phase 3-A: emit_string型注釈追加 * - Phase 3-A: emit_string 型注釈追加
* - Phase 3-B: BinOp(Add)型注釈強化 * - Phase 3-B: BinOp(Add) 型注釈強化
* - Phase 3-C: StaticCompiler文字列メソッド→StringBox正規化 * - Phase 3-C: StaticCompiler 文字列メソッド→ StringBox 正規化
*
* 本テストでは、Stage‑1 CLI 全体ではなく:
* - `string_helpers.hako` + 最小 Main のみをフィクスチャとして読み込み、
* - StringHelpers.skip_ws/2 内部の `.length()` が StringBox.length に正規化されること、
* - かつ MIR verify + VM 実行が通ること
* を小さな箱で固定する。
* *
* ## 検証項目 * ## 検証項目
* 1. MIR compile + verify が通る * 1. MIR compile + verify が通る
* 2. VM実行でRC=0（エラー落ちしない） * 2. VM 実行で RC=0（receiver 捏造バグがない）
* 3. StringBox.length に正規化されている * 3. StringBox.length に正規化されている
