+
+#### ✅ 無題ページ関連フック完全移行完了
+- ✅ **`useIsUntitledPage`**: 無題ページ状態取得(シンプルなboolean)
+- ✅ **`useSetIsUntitledPage`**: 無題ページ状態設定(直接的なsetter)
+
+#### 🚀 移行の成果と技術的特徴
+
+**1. シンプルなBoolean状態パターン確立**
+```typescript
+// Atom定義(シンプル)
+const isUntitledPageAtom = atom<boolean>(false);
+
+// 読み取り専用フック
+export const useIsUntitledPage = (): boolean => {
+  return useAtomValue(isUntitledPageAtom);
+};
+
+// セッター専用フック(useSetAtom直接使用)
+export const useSetIsUntitledPage = () => {
+  return useSetAtom(isUntitledPageAtom);
+};
+```
+
+**2. SWR後方互換性の完全排除**
+- **Before**: SWR response形式(`{ data: boolean, mutate: function }`)
+- **After**: 直接的なboolean値とsetter関数
+- **メリット**: シンプルで理解しやすい、不要な複雑性の排除
+
+**3. 使用箇所の完全移行**
+- **読み取り**: `const { data: isUntitled } = useIsUntitledPage()` → `const isUntitled = useIsUntitledPage()`
+- **変更**: `const { mutate } = useIsUntitledPage()` → `const setIsUntitled = useSetIsUntitledPage()`
+- **直接呼び出し**: `mutate(value)` → `setIsUntitled(value)`
+
+#### 📊 移行影響範囲
+- **新ファイル**: `states/ui/untitled-page.ts`(シンプルな実装)
+- **移行箇所**: 5個のファイル(PageTitleHeader.tsx, PageEditor.tsx, page-path-rename-utils.ts, use-create-page.tsx, use-update-page.tsx)
+- **テスト修正**: PageTitleHeader.spec.tsx(モック戻り値を `{ data: boolean }` → `boolean` に変更)
+- **旧コード削除**: `stores/ui.tsx` からの `useIsUntitledPage` 削除完了
+
+#### 🎯 設計原則の明確化
+- **SWR後方互換性不要時**: 直接的なgetter/setterパターンを採用
+- **パフォーマンス優先**: `useAtomValue` + `useSetAtom` の分離により最適化
+- **複雑性排除**: 不要なwrapper関数やcallback不要
+- **型安全性**: TypeScriptによる完全な型チェック

+   - `useIsAbleToShowTagLabel` - タグラベル表示判定(1ファイル使用、boolean計算)

 2. **追加SWRフック検討**: その他のSWR使用箇所の調査
 3. **AI機能のモーダル**: OpenAI関連のモーダル状態の統合検討
 4. **エディタパッケージ統合**: `@growi/editor`内のモーダル状態の統合
