-
-## 📊 現在の進捗サマリー
-
-### 🎯 **移行完了ステータス**
-- **総移行完了数**: **45個のフック・状態**
-- **完了カテゴリ**: 6つの主要カテゴリ完全移行済み
-
-| カテゴリ | 完了数 | ステータス |
-|---------|--------|-----------|
-| モーダル状態 | 17個 | ✅ 100%完了 |
-| デバイス状態 | 4個 | ✅ Phase 1完了 |
-| TOC状態 | 4個 | ✅ 完全完了 |

-| useContextSWR系・機能別states | 9個 | ✅ 完全完了 |
-| 基本Jotai状態管理 | 4個 | ✅ 完全完了 |
-
-### 🏆 **主要な技術成果**
-1. **パフォーマンス向上**: Derived Atom、Bundle Splitting、自動メモ化
-2. **統一されたAPIパターン**: 10種類の実装パターン確立
-3. **型安全性**: TypeScript完全対応、全型チェック成功
-4. **責務分離**: 機能別statesディレクトリ、server-configurations直接化
-5. **複雑状態管理**: Map・Set等の効率的なJotai管理パターン確立
-
-## 🔮 今後の発展可能性
-
-### 次のフェーズ候補（Phase 4）
-1. **残存SWRフック検討**: `stores/editor.tsx`等の残存SWR使用箇所調査
-   - `useCurrentIndentSize`, `useEditorSettings`, `usePageTagsForEditors` 等
-2. **AI機能のモーダル**: OpenAI関連の追加モーダル状態の統合検討
-3. **エディタパッケージ統合**: `@growi/editor`内のモーダル状態の統合
-4. **他モジュールへのDerived Atom適用**: 複雑な計算ロジックを持つ他のフックの調査・移行
-5. **レガシーSWRクリーンアップ**: データフェッチ系以外のSWR使用箇所の整理
-
-### クリーンアップ候補
-- **完了済み**: `stores/modal.tsx`、`stores/ui.tsx`、`stores-universal/context.tsx`（一部）、`stores/use-static-swr.ts` 完全削除済み
-- **残存調査対象**: `stores/editor.tsx`, `stores/user.tsx`, `stores/page.tsx`, `stores/comment.tsx`等
-
-## 🔄 最新の更新履歴
-
-### 2025-09-25: 🎉 **基本Jotai状態管理移行完全完了！**
-- useUnsavedWarning, useCommentEditorsDirtyMap 移行完了（副作用統合パターン）
-- usePageTreeDescCountMap, usePageTreeDescCountMapAction 移行完了（複雑状態管理パターン）
-- Map操作最適化、useCallback参照安定化、Router event integration確立
-
-### 2025-09-25: 🎉 **useContextSWR系・機能別states移行完全完了！**
-- OpenAI専用states作成（features/openai/client/states/）
-- useIsEnableUnifiedMergeView のJotai移行＋Actions Pattern確立
-- server-configurations直接Atom化（wrapper hook削除、一貫性向上）
-- 不要フック・ファイル削除（useIsBlinkedHeaderAtBoot, useCustomizeTitle, use-static-swr.ts）
-
-### 2025-09-25: 🎉 **ページ権限判定状態移行完全完了！**
-- 高パフォーマンスDerived Atom移行3フック + Direct Hook維持2フック
-- 特殊名Export方式（`_atomsForDerivedAbilities`）の確立
-- Derived Atom採用ガイドライン策定
-- stores/ui.tsx 完全削除完了
-
-### 2025-09-11: **TOC状態・無題ページ状態移行完了**
-- RefObjectパターン、Dynamic Import、シンプルBoolean状態パターン確立
-
-### 2025-09-05: **モーダル移行プロジェクト100%完了**
-- 全17個のモーダルがJotaiベースに統一
-- パフォーマンス最適化パターン全適用完了
-
-## 🎯 確立された技術ベストプラクティス
-
-### 最重要パターン
-1. **特殊名Export方式 + Derived Atom採用判断**: 複雑度・使用頻度による最適化戦略
-2. **機能別states分離 + server-configurations直接化**: 責務明確化と軽量化
-3. **複雑状態管理 + 副作用統合パターン**: Map・Set管理とRouter integration
-
-### 移行判断基準
-- **高複雑度・高使用頻度**: Derived Atom化（⭐⭐⭐）
-- **中複雑度・中使用頻度**: Derived Atom化（⭐⭐）
-- **低複雑度・低使用頻度**: Direct Hook維持（⭐）
-- **データフェッチ系**: SWR維持
-- **サーバー設定系**: 直接atom使用
-- **機能専用**: 専用statesディレクトリ作成
-
-## 📋 次回移行時の準備事項
-
-### 事前調査項目
-1. **SWR使用箇所の分類**: データフェッチ vs 状態管理
-2. **複雑度評価**: 依存関係の数・計算コスト
-3. **使用頻度調査**: レンダリング回数・共有度
-4. **既存atom確認**: 新規実装 vs 既存atom活用
-
-### 移行優先順位
-1. **useContextSWR系** → server-configurations直接化
-2. **useSWRStatic系** → Jotaiベース状態管理
-3. **複雑計算フック** → Derived Atom化
-4. **機能専用状態** → 専用statesディレクトリ

+
+## Latest Migration Session Results
+
+### Successfully Migrated (3 hooks):
+
+1. **useWaitingSaveProcessing** → `apps/app/src/states/ui/waiting-save-processing.ts`
+   - Simple boolean state for save processing flag
+   - Usage: PageEditor.tsx, SavePageControls.tsx
+
+2. **useCurrentIndentSize** → `apps/app/src/states/ui/current-indent-size.ts`
+   - Number state with fallback to defaultIndentSizeAtom
+   - Derived atom pattern for fallback logic
+   - Usage: PageEditor.tsx
+
+3. **usePageTagsForEditors** → `apps/app/src/states/ui/page-tags-for-editors.ts`
+   - String array state with external data synchronization
+   - Maintains sync() method compatibility
+   - Usage: page-operation.ts
+
+### Kept as SWR (1 hook):
+- **useEditorSettings** - True data fetching with server synchronization
+
+### Technical Patterns Used:
+- Legacy SWR compatible wrappers for gradual migration
+- Derived atom pattern with fallback (useCurrentIndentSize)
+- External data sync pattern (usePageTagsForEditors) 
+- Status/Actions separation pattern
+- Migration comments in legacy implementations
+
+### Files Updated:
+- Created 3 new Jotai state files
+- Updated imports in PageEditor.tsx, SavePageControls.tsx, page-operation.ts
+- Added migration comments to legacy SWR implementations
+- All type checking passes
+
+## Migration Guidelines Applied:
+- ✅ Parafance optimization hook separation
+- ✅ Legacy SWR compatibility wrappers
+- ✅ Derived atom pattern for complex calculations
+- ✅ Package boundary respect
+- ✅ Established directory structure
+
+## Next Steps:
+- Remove legacy SWR implementations after full migration validation
+- Investigate additional stores/ directories for more migration candidates
+- Continue systematic replacement of inappropriate SWR usage
