**ファイル**:
- `/home/tomoaki/git/hakorune-selfhost/src/mir/builder/compilation_context.rs` (新規作成, 405 行)
**統合方法**:
- `MirBuilder``comp_ctx: CompilationContext` フィールドを追加
- 既存フィールドは `#[deprecated]` でマーク(後方互換性維持)
- `CompilationContext::with_plugin_sigs()` で plugin_method_sigs を初期化
- 全 15 フィールドが comp_ctx に統合され、SSOT 化完了
**特徴**:
- **Box コンパイル**: BoxCompilationContext で static box コンパイル分離
- **PHI 予約**: reserved_value_ids で LoopHeaderPhiBuilder の ValueId 衝突を防止

- **型情報**: type_registry で型情報一元管理 (NYASH_USE_TYPE_REGISTRY=1)
- **Slot レジストリ**: current_slot_registry で関数スコープ観測
**テスト結果**:
-`cargo build --release` 成功 (469 warnings - deprecated フィールド使用)
-`cargo test --release --lib` - 1029/1033 PASS (4 tests 失敗は既存問題)
-`phase135_trim_mir_verify.sh` - PASS
**影響範囲**:
- builder 内の compilation 関連フィールドを使用中のコードは全て comp_ctx 経由に移行可能
- 段階的移行により破壊的変更なし

## 設計原則
1. **段階的移行** - 全フィールドを一度に移行せず、1-2 Context ずつ
2. **後方互換性** - 既存の public API は維持(内部で Context 経由に変更)
3. **Box-First** - 各 Context は独立した struct として配置
4. **テスト駆動** - 各段階で全テストが PASS することを確認

## 次のステップ: Legacy フィールド削除
Phase 136 follow-up の全 7 Context が完了しました!次は **Phase 2: レガシーフィールド削除** です。
**Phase 2 タスク**:
1. builder.rs から `#[deprecated]` フィールドを削除
2. sync helper メソッドを削除 (`sync_*_to_legacy`, `sync_legacy_to_*`)
3. 全ファイルを ctx 経由に移行 (段階的、Context ごと)
- `rg "self\.value_types" src/mir/builder/``self.type_ctx.value_types`
- `rg "self\.value_gen" src/mir/builder/``self.core_ctx.value_gen`
- 等々、全フィールド
4. テスト実行(各 Context 削除後)
5. コミット1-2 回に分割可能)
