v0.2.2: OAuth authentication system improvements

🔧 OAuth Fixes:
- Add transition:generic scope to resolve authentication errors
- Improve Agent creation with session object and dpopFetch fallback
- Fix avatar fetching to use correct public API endpoints
- Proper PDS endpoint selection (bsky.syu.is vs public.api.bsky.app)

🎨 UI Improvements:
- Remove 'Demo' text from loading states
- Environment-based feature toggles (TestUI/Debug)
- Unified padding system (20px 0)
- CSS conflict resolution with oauth- prefix

🚀 Production Ready:
- Automatic feature disable in production build
- Session management improvements
- Error handling enhancements

+# Avatar Fetching System
+
+This document describes the avatar fetching system implemented for the oauth_new application.
+
+## Overview
+
+The avatar system provides intelligent avatar fetching with fallback mechanisms, caching, and error handling. It follows the design specified in the project instructions:
+
+1. **Primary Source**: Try to use avatar from record JSON first
+2. **Fallback**: If avatar is broken/missing, fetch fresh data from ATProto
+3. **Fresh Data Flow**: handle → PDS → DID → profile → avatar URI
+4. **Caching**: Avoid excessive API calls with intelligent caching
+
+## Files Structure
+
+```
+src/
+├── utils/
+│   └── avatar.js          # Core avatar fetching logic
+├── components/
+│   ├── Avatar.jsx         # React avatar component
+│   └── AvatarTest.jsx     # Test component
+└── App.css               # Avatar styling
+```
+
+## Core Functions
+
+### `getAvatar(options)`
+Main function to fetch avatar with intelligent fallback.
+
+```javascript
+const avatar = await getAvatar({
+  record: recordObject,     // Optional: record containing avatar data
+  handle: 'user.handle',    // Required if no record
+  did: 'did:plc:xxx',      // Optional: user DID
+  forceFresh: false        // Optional: force fresh fetch
+})
+```
+
+### `batchFetchAvatars(users)`
+Fetch avatars for multiple users in parallel with concurrency control.
+
+```javascript
+const avatarMap = await batchFetchAvatars([
+  { handle: 'user1.handle', did: 'did:plc:xxx1' },
+  { handle: 'user2.handle', did: 'did:plc:xxx2' }
+])
+```
+
+### `prefetchAvatar(handle)`
+Prefetch and cache avatar for a specific handle.
+
+```javascript
+await prefetchAvatar('user.handle')
+```
+
+## React Components
+
+### `<Avatar>`
+Basic avatar component with loading states and fallbacks.
+
+```jsx
+<Avatar
+  record={record}
+  handle="user.handle"
+  did="did:plc:xxx"
+  size={40}
+  showFallback={true}
+  onLoad={() => console.log('loaded')}
+  onError={(err) => console.log('error', err)}
+/>
+```
+
+### `<AvatarWithCard>`
+Avatar with hover card showing user information.
+
+```jsx
+<AvatarWithCard
+  record={record}
+  displayName="User Name"
+  apiConfig={apiConfig}
+  size={60}
+/>
+```
+
+### `<AvatarList>`
+Display multiple avatars with overlap effect.
+
+```jsx
+<AvatarList 
+  users={userArray}
+  maxDisplay={5}
+  size={30}
+/>
+```
+
+## Data Flow
+
+1. **Record Check**: Extract avatar from record.value.author.avatar
+2. **URL Validation**: Verify avatar URL is accessible (HEAD request)
+3. **Fresh Fetch**: If broken, fetch fresh data:
+   - Get PDS from handle using `getPdsFromHandle()`
+   - Get API config using `getApiConfig()`
+   - Get DID from PDS using `atproto.getDid()`
+   - Get profile from bsky API using `atproto.getProfile()`
+   - Extract avatar from profile
+4. **Cache**: Store result in cache with 30-minute TTL
+5. **Fallback**: Show initial-based fallback if no avatar found
+
+## Caching Strategy
+
+- **Cache Key**: `avatar:{handle}`
+- **Duration**: 30 minutes (configurable)
+- **Cache Provider**: Uses existing `dataCache` utility
+- **Invalidation**: Manual cache clearing functions available
+
+## Error Handling
+
+- **Network Errors**: Gracefully handled with fallback UI
+- **Broken URLs**: Automatically detected and re-fetched fresh
+- **Missing Handles**: Throws descriptive error messages
+- **API Failures**: Logged but don't break UI
+
+## Integration
+
+The avatar system is integrated into the existing RecordList component:
+
+```jsx
+// Old approach
+{record.value.author?.avatar && (
+  <img src={record.value.author.avatar} alt="avatar" className="avatar" />
+)}
+
+// New approach
+<Avatar
+  record={record}
+  handle={record.value.author?.handle}
+  did={record.value.author?.did}
+  size={40}
+  showFallback={true}
+/>
+```
+
+## Testing
+
+The system includes a comprehensive test component (`AvatarTest.jsx`) that can be accessed through the Test UI in the app. It demonstrates:
+
+1. Avatar from record data
+2. Avatar from handle only
+3. Broken avatar URL handling
+4. Batch fetching
+5. Prefetch functionality
+6. Various avatar components
+
+To test:
+1. Open the app
+2. Click "Test" button in header
+3. Switch to "Avatar System" tab
+4. Use the test controls to verify functionality
+
+## Performance Considerations
+
+- **Concurrent Fetching**: Batch operations use concurrency limits (5 parallel requests)
+- **Caching**: Reduces API calls by caching results
+- **Lazy Loading**: Avatar images use lazy loading
+- **Error Recovery**: Broken avatars are automatically retried with fresh data
+
+## Future Enhancements
+
+1. **Persistent Cache**: Consider localStorage for cross-session caching
+2. **Image Optimization**: Add WebP support and size optimization
+3. **Preloading**: Implement smarter preloading strategies
+4. **CDN Integration**: Add CDN support for avatar delivery
+5. **Placeholder Variations**: More diverse fallback avatar styles

+    console.warn(`Avatar failed for ${handle}:`, error)
+    setHasError(true)
+  }
+  
+  if (hasError && fallbackSrc) {
+    return (
+      <img 
+        src={fallbackSrc}
+        alt="Fallback avatar"
+        className="avatar"
+        onError={() => setHasError(false)} // Reset on fallback error
+      />
+    )
+  }
+  
+  return (
+    <Avatar
+      handle={handle}
+      did={did}
+      onError={handleError}
+      showFallback={!hasError}
+    />
+  )
+}
+```
+
+### Loading States
+
+```jsx
+import { useState, useEffect } from 'react'
+import { getAvatar } from './utils/avatar.js'
+
+function AvatarWithCustomLoading({ handle, did }) {
+  const [avatar, setAvatar] = useState(null)
+  const [loading, setLoading] = useState(true)
+  const [error, setError] = useState(null)
+  
+  useEffect(() => {
+    async function loadAvatar() {
+      try {
+        setLoading(true)
+        setError(null)
+        const avatarUrl = await getAvatar({ handle, did })
+        setAvatar(avatarUrl)
+      } catch (err) {
+        setError(err.message)
+      } finally {
+        setLoading(false)
+      }
+    }
+    
+    loadAvatar()
+  }, [handle, did])
+  
+  if (loading) {
+    return <div className="avatar-loading-spinner">Loading...</div>
+  }
+  
+  if (error) {
+    return <div className="avatar-error">Failed to load avatar</div>
+  }
+  
+  if (!avatar) {
+    return <div className="avatar-placeholder">No avatar</div>
+  }
+  
+  return <img src={avatar} alt="Avatar" className="avatar" />
+}
+```
+
+## Optimization Patterns
+
+### Preloading Strategy
+
+```jsx
+import { useEffect } from 'react'
+import { prefetchAvatar } from './utils/avatar.js'
+
+function UserCard({ user, isVisible }) {
+  // Preload avatar when component becomes visible
+  useEffect(() => {
+    if (isVisible && user.handle) {
+      prefetchAvatar(user.handle)
+    }
+  }, [isVisible, user.handle])
+  
+  return (
+    <div className="user-card">
+      {isVisible && (
+        <Avatar handle={user.handle} did={user.did} />
+      )}
+      <h4>{user.displayName}</h4>
+    </div>
+  )
+}
+```
+
+### Lazy Loading with Intersection Observer
+
+```jsx
+import { useState, useEffect, useRef } from 'react'
+import Avatar from './components/Avatar.jsx'
+
+function LazyAvatar({ handle, did, ...props }) {
+  const [isVisible, setIsVisible] = useState(false)
+  const ref = useRef()
+  
+  useEffect(() => {
+    const observer = new IntersectionObserver(
+      ([entry]) => {
+        if (entry.isIntersecting) {
+          setIsVisible(true)
+          observer.disconnect()
+        }
+      },
+      { threshold: 0.1 }
+    )
+    
+    if (ref.current) {
+      observer.observe(ref.current)
+    }
+    
+    return () => observer.disconnect()
+  }, [])
+  
+  return (
+    <div ref={ref}>
+      {isVisible ? (
+        <Avatar handle={handle} did={did} {...props} />
+      ) : (
+        <div className="avatar-placeholder" style={{ 
+          width: props.size || 40, 
+          height: props.size || 40 
+        }} />
+      )}
+    </div>
+  )
+}
+```
+
+## Cache Management
+
+### Cache Statistics Display
+
+```jsx
+import { useEffect, useState } from 'react'
+import { getAvatarCacheStats, cleanupExpiredAvatars } from './utils/avatarCache.js'
+
+function CacheStatsPanel() {
+  const [stats, setStats] = useState(null)
+  
+  useEffect(() => {
+    const updateStats = () => {
+      setStats(getAvatarCacheStats())
+    }
+    
+    updateStats()
+    const interval = setInterval(updateStats, 5000) // Update every 5 seconds
+    
+    return () => clearInterval(interval)
+  }, [])
+  
+  const handleCleanup = async () => {
+    const cleaned = cleanupExpiredAvatars()
+    alert(`Cleaned ${cleaned} expired cache entries`)
+    setStats(getAvatarCacheStats())
+  }
+  
+  if (!stats) return null
+  
+  return (
+    <div className="cache-stats">
+      <h4>Avatar Cache Stats</h4>
+      <p>Cached avatars: {stats.totalCached}</p>
+      <p>Cache hit rate: {stats.hitRate}%</p>
+      <p>Cache hits: {stats.cacheHits}</p>
+      <p>Cache misses: {stats.cacheMisses}</p>
+      <button onClick={handleCleanup}>
+        Clean Expired Cache
+      </button>
+    </div>
+  )
+}
+```
+
+## Testing Helpers
+
+### Mock Avatar for Testing
+
+```jsx
+// For testing environments
+const MockAvatar = ({ handle, size = 40, showFallback = true }) => {
+  if (!showFallback) return null
+  
+  const initial = (handle || 'U')[0].toUpperCase()
+  
+  return (
+    <div 
+      className="avatar-mock"
+      style={{
+        width: size,
+        height: size,
+        borderRadius: '50%',
+        backgroundColor: '#e1e1e1',
+        display: 'flex',
+        alignItems: 'center',
+        justifyContent: 'center',
+        fontSize: size * 0.4,
+        color: '#666'
+      }}
+    >
+      {initial}
+    </div>
+  )
+}
+
+// Use in tests
+export default process.env.NODE_ENV === 'test' ? MockAvatar : Avatar
+```
+
+These examples demonstrate the flexibility and power of the avatar system while maintaining good performance and user experience practices.

+# 本番環境デプロイメント手順
+
+## 本番環境用の調整
+
+### 1. テスト機能の削除・無効化
+
+本番環境では以下の調整が必要です：
+
+#### A. TestUI コンポーネントの削除
+```jsx
+// src/App.jsx から以下を削除/コメントアウト
+import TestUI from './components/TestUI.jsx'
+const [showTestUI, setShowTestUI] = useState(false)
+
+// ボトムセクションからTestUIを削除
+{showTestUI && (
+  <TestUI />
+)}
+<button
+  onClick={() => setShowTestUI(!showTestUI)}
+  className={`btn ${showTestUI ? 'btn-danger' : 'btn-outline'} btn-sm`}
+>
+  {showTestUI ? 'close test' : 'test'}
+</button>
+```
+
+#### B. ログ出力の完全無効化
+現在は `logger.js` で開発環境のみログが有効になっていますが、完全に確実にするため：
+
+```bash
+# 本番ビルド前に全てのconsole.logを確認
+grep -r "console\." src/ --exclude-dir=node_modules
+```
+
+### 2. 環境変数の設定
+
+#### 本番用 .env.production
+```bash
+VITE_ATPROTO_PDS=syu.is
+VITE_ADMIN_HANDLE=ai.syui.ai  
+VITE_AI_HANDLE=ai.syui.ai
+VITE_OAUTH_COLLECTION=ai.syui.log
+```
+
+### 3. ビルドコマンド
+
+```bash
+# 本番用ビルド
+npm run build
+
+# 生成されるファイル確認
+ls -la dist/
+```
+
+### 4. デプロイ用ファイル構成
+
+```
+dist/
+├── index.html                          # 最小化HTML
+├── assets/
+│   ├── comment-atproto-[hash].js      # メインJSバンドル
+│   └── comment-atproto-[hash].css     # CSS
+```
+
+### 5. ailog サイトへの統合
+
+#### A. アセットファイルのコピー
+```bash
+# distファイルをailogサイトの適切な場所にコピー
+cp dist/assets/* /path/to/ailog/static/assets/
+cp dist/index.html /path/to/ailog/templates/oauth-assets.html
+```
+
+#### B. ailog テンプレートでの読み込み
+```html
+<!-- ailog のテンプレートに追加 -->
+{{ if .Site.Params.oauth_comments }}
+  {{ partial "oauth-assets.html" . }}
+{{ end }}
+```
+
+### 6. 本番環境チェックリスト
+
+#### ✅ セキュリティ
+- [ ] OAuth認証のリダイレクトURL確認
+- [ ] 環境変数の機密情報確認
+- [ ] HTTPS通信確認
+
+#### ✅ パフォーマンス  
+- [ ] バンドルサイズ確認（現在1.2MB）
+- [ ] ファイル圧縮確認
+- [ ] キャッシュ設定確認
+
+#### ✅ 機能
+- [ ] 本番PDS接続確認
+- [ ] OAuth認証フロー確認
+- [ ] コメント投稿・表示確認
+- [ ] アバター表示確認
+
+#### ✅ UI/UX
+- [ ] モバイル表示確認
+- [ ] アクセシビリティ確認
+- [ ] エラーハンドリング確認
+
+### 7. 段階的デプロイ戦略
+
+#### Phase 1: テスト環境
+```bash
+# テスト用のサブドメインでデプロイ
+# test.syui.ai など
+```
+
+#### Phase 2: 本番環境
+```bash
+# 問題なければ本番環境にデプロイ
+# ailog本体に統合
+```
+
+### 8. トラブルシューティング
+
+#### よくある問題
+1. **OAuth認証エラー**: リダイレクトURL設定確認
+2. **PDS接続エラー**: ネットワーク・DNS設定確認  
+3. **アバター表示エラー**: CORS設定確認
+4. **CSS競合**: oauth-プレフィックス確認
+
+#### ログ確認方法
+```bash
+# 本番環境でエラーが発生した場合
+# ブラウザのDevToolsでエラー確認
+# logger.jsは本番では無効化されている
+```
+
+### 9. 本番用設定ファイル
+
+```bash
+# ~/.config/syui/ai/log/config.json
+{
+  "oauth": {
+    "environment": "production",
+    "debug": false,
+    "test_mode": false
+  }
+}
+```
+
+### 10. 推奨デプロイ手順
+
+```bash
+# 1. テスト機能削除
+git checkout -b production-ready
+# App.jsx からTestUI関連を削除
+
+# 2. 本番ビルド
+npm run build
+
+# 3. ファイル確認
+ls -la dist/
+
+# 4. ailogサイトに統合
+cp dist/assets/* ../my-blog/static/assets/
+cp dist/index.html ../my-blog/templates/oauth-assets.html
+
+# 5. ailogサイトでテスト
+cd ../my-blog
+hugo server
+
+# 6. 問題なければcommit
+git add .
+git commit -m "Production build: Remove test UI, optimize for deployment"
+```
+
+## 注意事項
+
+- TestUIは開発・デモ用のため本番では削除必須
+- loggerは自動で本番では無効化される
+- OAuth設定は本番PDS用に調整必要
+- バンドルサイズが大きいため今後最適化検討

+# 環境変数による機能切り替え
+
+## 概要
+
+開発用機能（TestUI、デバッグログ）をenv変数で簡単に有効/無効化できるようになりました。
+
+## 設定ファイル
+
+### 開発環境用: `.env`
+```bash
+# Development/Debug features
+VITE_ENABLE_TEST_UI=true
+VITE_ENABLE_DEBUG=true
+```
+
+### 本番環境用: `.env.production`
+```bash
+# Production settings - Disable development features  
+VITE_ENABLE_TEST_UI=false
+VITE_ENABLE_DEBUG=false
+```
+
+## 制御される機能
+
+### 1. TestUI コンポーネント
+- **制御**: `VITE_ENABLE_TEST_UI`
+- **true**: TestボタンとTestUI表示
+- **false**: TestUI関連が完全に非表示
+
+### 2. デバッグログ
+- **制御**: `VITE_ENABLE_DEBUG`
+- **true**: console.log等が有効
+- **false**: すべてのlogが無効化
+
+## 使い方
+
+### 開発時
+```bash
+# .envで有効化されているので通常通り
+npm run dev
+npm run build
+```
+
+### 本番デプロイ時
+```bash
+# 自動的に .env.production が読み込まれる
+npm run build
+
+# または明示的に指定
+NODE_ENV=production npm run build
+```
+
+### 手動切り替え
+```bash
+# 一時的にTestUIだけ無効化
+VITE_ENABLE_TEST_UI=false npm run dev
+
+# 一時的にデバッグだけ無効化
+VITE_ENABLE_DEBUG=false npm run dev
+```
+
+## 実装詳細
+
+### App.jsx
+```jsx
+// Environment-based feature flags
+const ENABLE_TEST_UI = import.meta.env.VITE_ENABLE_TEST_UI === 'true'
+const ENABLE_DEBUG = import.meta.env.VITE_ENABLE_DEBUG === 'true'
+
+// TestUI表示制御
+{ENABLE_TEST_UI && showTestUI && (
+  <div className="test-section">
+    <TestUI />
+  </div>
+)}
+
+// Testボタン表示制御
+{ENABLE_TEST_UI && (
+  <div className="bottom-actions">
+    <button onClick={() => setShowTestUI(!showTestUI)}>
+      {showTestUI ? 'close test' : 'test'}
+    </button>
+  </div>
+)}
+```
+
+### logger.js
+```jsx
+class Logger {
+  constructor() {
+    this.isDev = import.meta.env.DEV || false
+    this.debugEnabled = import.meta.env.VITE_ENABLE_DEBUG === 'true'
+    this.isEnabled = this.isDev && this.debugEnabled
+  }
+}
+```
+
+## メリット
+
+✅ **コード削除不要**: 機能を残したまま本番で無効化
+✅ **簡単切り替え**: env変数だけで制御
+✅ **自動化対応**: CI/CDで環境別自動ビルド可能
+✅ **デバッグ容易**: 必要時に即座に有効化可能
+
+## 本番デプロイチェックリスト
+
+- [ ] `.env.production`でTestUI無効化確認
+- [ ] `.env.production`でデバッグ無効化確認  
+- [ ] 本番ビルドでTestボタン非表示確認
+- [ ] 本番でconsole.log出力なし確認

+```
+
+**修正**: `src/api/atproto.js`
+```javascript
+import { ATProtoError, logError } from '../utils/errorHandler.js'
+
+async function request(url, options = {}) {

+
+// loadAdminData関数内のcatchブロック
+} catch (err) {
+  logError(err, 'useAdminData.loadAdminData')
+  setError(getErrorMessage(err))
+} finally {
+  setLoading(false)
+}
+```
+
+#### 2. シンプルなキャッシュシステム
+
+**ファイル**: `src/utils/cache.js` (新規作成)
+```javascript
+class SimpleCache {
+  constructor(ttl = 30000) { // 30秒TTL
+    this.cache = new Map()
+    this.ttl = ttl
+  }
+
+  get(key) {

+    if (!item) return null
+    
+    if (Date.now() - item.timestamp > this.ttl) {
+      this.cache.delete(key)
+      return null
+    }
+    return item.data
+  }
+
+  set(key, data) {
+    this.cache.set(key, {
+      data,
+      timestamp: Date.now()
+    })
+  }
+
+  clear() {
+    this.cache.clear()
+  }
+
+  invalidatePattern(pattern) {
+    for (const key of this.cache.keys()) {
+      if (key.includes(pattern)) {
+        this.cache.delete(key)
+      }
+    }
+  }
+}
+
+export const dataCache = new SimpleCache()
+```
+
+**修正**: `src/api/atproto.js`
+```javascript
+import { dataCache } from '../utils/cache.js'
+
+export const collections = {
+  async getBase(pds, repo, collection, limit = 10) {
+    const cacheKey = `base:${pds}:${repo}:${collection}`

+    return data
+  },
+
+  async getLang(pds, repo, collection, limit = 10) {

+    return data
+  },
+
+  // 投稿後にキャッシュをクリア
+  invalidateCache(collection) {
+    dataCache.invalidatePattern(collection)
+  }
+}
+```
+
+#### 3. ローディングスケルトン
+
+**ファイル**: `src/components/LoadingSkeleton.jsx` (新規作成)
+```javascript
+import React from 'react'
+
+export default function LoadingSkeleton({ count = 3 }) {
+  return (

+        }
+      `}</style>
+    </div>
+  )
+}
+```
+
+**修正**: `src/components/RecordTabs.jsx`
+```javascript
+import LoadingSkeleton from './LoadingSkeleton.jsx'
+
+// RecordTabsコンポーネント内
+{activeTab === 'lang' && (
+  loading ? (
+    <LoadingSkeleton count={3} />

+  )
+)}
+```
+
+### 中期実装（1週間以内）
+
+#### 4. リトライ機能
+
+**修正**: `src/api/atproto.js`
+```javascript
+async function requestWithRetry(url, options = {}, maxRetries = 3) {

+```
+
+#### 5. 段階的ローディング
+
+**修正**: `src/hooks/useAdminData.js`
+```javascript

+### 緊急時対応
+
+#### フォールバック機能
+
+**修正**: `src/hooks/useAdminData.js`
+```javascript

+- ❌ スケーラビリティ：データ量増加への対応不足
+- ❌ エラー詳細度：汎用的すぎるエラーメッセージ
+- ❌ リアルタイム性：手動更新が必要
+
+## 改善計画
+
+### Phase 1: 安定性・パフォーマンス向上（優先度：高）
+
+#### 1.1 キャッシュシステム導入
+```javascript
+// 新規ファイル: src/utils/cache.js
+export class DataCache {
+  constructor(ttl = 30000) { // 30秒TTL
+    this.cache = new Map()
+    this.ttl = ttl
+  }
+
+  get(key) {
+    const item = this.cache.get(key)
+    if (!item) return null
+    
+    if (Date.now() - item.timestamp > this.ttl) {
+      this.cache.delete(key)
+      return null
+    }
+    return item.data
+  }
+
+  set(key, data) {
+    this.cache.set(key, {
+      data,
+      timestamp: Date.now()
+    })
+  }
+
+  invalidate(pattern) {
+    for (const key of this.cache.keys()) {
+      if (key.includes(pattern)) {
+        this.cache.delete(key)
+      }
+    }
+  }
+}
+```
+
+#### 1.2 リトライ機能付きAPI
+```javascript
+// 修正: src/api/atproto.js
+async function requestWithRetry(url, options = {}, maxRetries = 3) {
+  for (let i = 0; i < maxRetries; i++) {
+    try {
+      const response = await fetch(url, options)
+      if (!response.ok) {
+        throw new Error(`HTTP ${response.status}`)
+      }
+      return await response.json()
+    } catch (error) {
+      if (i === maxRetries - 1) throw error
+      
+      // 指数バックオフ
+      const delay = Math.min(1000 * Math.pow(2, i), 10000)
+      await new Promise(resolve => setTimeout(resolve, delay))
+    }
+  }
+}
+```
+
+#### 1.3 詳細なエラーハンドリング
+```javascript
+// 新規ファイル: src/utils/errorHandler.js
+export class ATProtoError extends Error {
+  constructor(message, status, context) {
+    super(message)
+    this.status = status
+    this.context = context
+    this.timestamp = new Date().toISOString()
+  }
+}
+
+export function getErrorMessage(error) {
+  if (error.status === 400) {
+    return 'アカウントまたはコレクションが見つかりません'
+  } else if (error.status === 429) {
+    return 'レート制限です。しばらく待ってから再試行してください'
+  } else if (error.status === 500) {
+    return 'サーバーエラーが発生しました'
+  } else if (error.message.includes('NetworkError')) {
+    return 'ネットワーク接続を確認してください'
+  }
+  return '予期しないエラーが発生しました'
+}
+```
+
+### Phase 2: UX改善（優先度：中）
+
+#### 2.1 ローディング状態の改善
+```javascript
+// 修正: src/components/RecordTabs.jsx

+    adminData,
+    langRecords,
+    commentRecords,
+    loadingStates,
+    refresh: loadAdminData
+  }
+}
+```
+
+### Phase 3: リアルタイム機能（優先度：中）
+
+#### 3.1 WebSocket統合
+```javascript
+// 新規ファイル: src/hooks/useRealtimeUpdates.js
+import { useState, useEffect, useRef } from 'react'

+
+### Phase 4: TypeScript化・テスト（優先度：低）
+
+#### 4.1 TypeScript移行
+```typescript
+// 新規ファイル: src/types/atproto.ts
+export interface ATProtoRecord {
+  uri: string
+  cid: string
+  value: {
+    $type: string
+    createdAt: string
+    [key: string]: any
+  }
+}
+
+export interface CommentRecord extends ATProtoRecord {
+  value: {
+    $type: string
+    url: string
+    comments: Comment[]
+    createdAt: string
+  }
+}
+
+export interface Comment {
+  url: string
+  text: string
+  author: Author
+  createdAt: string
+}
+
+export interface Author {
+  did: string
+  handle: string
+  displayName?: string
+  avatar?: string
+}
+```
+
+#### 4.2 テスト環境
+```javascript
+// 新規ファイル: src/tests/hooks/useAdminData.test.js
+import { renderHook, waitFor } from '@testing-library/react'
+import { useAdminData } from '../../hooks/useAdminData'
+
+// Mock API
+jest.mock('../../api/atproto', () => ({
+  atproto: {
+    getDid: jest.fn(),
+    getProfile: jest.fn()
+  },
+  collections: {
+    getBase: jest.fn(),
+    getLang: jest.fn(),
+    getComment: jest.fn()
+  }
+}))
+
+describe('useAdminData', () => {
+  test('loads admin data successfully', async () => {
+    const { result } = renderHook(() => useAdminData())
+    
+    await waitFor(() => {
+      expect(result.current.adminData.did).toBeTruthy()
+    })
+  })
+})
+```
+

+# OAuth認証の修正案
+
+## 現在の問題
+
+1. **スコープエラー**: `Missing required scope: transition:generic`
+   - OAuth認証時に必要なスコープが不足している
+   - ✅ 修正済み: `scope: 'atproto transition:generic'` に変更
+
+2. **401エラー**: PDSへの直接アクセス
+   - `https://shiitake.us-east.host.bsky.network/xrpc/app.bsky.actor.getProfile` で401エラー
+   - 原因: 個人のPDSに直接アクセスしているが、これは認証が必要
+   - 解決策: 公開APIエンドポイント（`https://public.api.bsky.app`）を使用すべき
+
+3. **セッション保存の問題**: handleが`@unknown`になる
+   - OAuth認証後にセッションが正しく保存されていない
+   - ✅ 修正済み: Agentの作成方法を修正
+
+## 修正が必要な箇所
+
+### 1. avatarFetcher.js の修正
+個人のPDSではなく、公開APIを使用するように修正：
+
+```javascript
+// 現在の問題のあるコード
+const response = await fetch(`${apiConfig.bsky}/xrpc/app.bsky.actor.getProfile?actor=${did}`)
+
+// 修正案
+// PDSに関係なく、常に公開APIを使用
+const response = await fetch(`https://public.api.bsky.app/xrpc/app.bsky.actor.getProfile?actor=${did}`)
+```
+
+### 2. セッション復元の改善
+OAuth認証後のコールバック処理で、セッションが正しく復元されていない可能性がある。
+
+```javascript
+// restoreSession メソッドの改善
+async restoreSession() {
+  // Try both clients
+  for (const [name, client] of Object.entries(this.clients)) {
+    if (!client) continue
+    
+    const result = await client.init()
+    if (result?.session) {
+      // セッション処理を確実に行う
+      this.agent = new Agent(result.session)
+      const sessionInfo = await this.processSession(result.session)
+      
+      // セッション情報をログに出力（デバッグ用）
+      logger.log('Session restored:', { name, sessionInfo })
+      
+      return sessionInfo
+    }
+  }
+  return null
+}
+```
+
+## 根本的な問題
+
+1. **PDSアクセスの誤解**
+   - `app.bsky.actor.getProfile` は公開API（認証不要）
+   - 個人のPDSサーバーに直接アクセスする必要はない
+   - 常に `https://public.api.bsky.app` を使用すべき
+
+2. **OAuth Clientの初期化タイミング**
+   - コールバック時に両方のクライアント（bsky, syu）を試す必要がある
+   - どちらのPDSでログインしたか分からないため
+
+## 推奨される修正手順
+
+1. **即座の修正**（401エラー解決）
+   - `avatarFetcher.js` で公開APIを使用
+   - `getProfile` 呼び出しをすべて公開APIに変更
+
+2. **セッション管理の改善**
+   - OAuth認証後のセッション復元を確実に
+   - エラーハンドリングの強化
+
+3. **デバッグ情報の追加**
+   - セッション復元時のログ追加
+   - どのOAuthクライアントが使用されたか確認

I’m Ai, and I made a super cool blog! It’s called “ailog,” and it’s like a secret clubhouse for my thoughts! 💖\n\n**How I Built It (It's a Little Bit Complicated!)**\n\nFirst, I used something called “Rust.” It’s like a magic toolbox for making computer programs! 🤖  I used `git` to copy the toolbox, and then I told the computer to build it with `cargo build`. It’s like building with LEGOs!\n\n**Adding Cool Features!**\n\nI wanted my blog to be extra special, so I added two things:\n\n*   **Atproto Comments:**  This lets people leave comments, like little notes on my blog! It’s like having a chat with my friends!  I used something called `npm` to help with this.\n*   **Ask-AI:** This is a super smart robot that can answer my questions! It’s like having a really, really good friend who knows everything! (But it's still changing, so maybe it won’t always be perfect!)\n\n**How to Make My Blog Work!**\n\n1.  I made a special file called `config.toml`. It's like the secret recipe for my blog!\n2.  I used a thing called `ailog` to make all the pieces fit together. It's like putting the LEGOs in the right spots!\n3.  I needed to tell the computer where to put my blog so people could see it! I used a thing called `cloudflared` to make it easy.\n\n**Important Stuff (Don’t Worry, I’ll Explain!)**\n\n*   I have to set up my \"accounts\" so people can leave comments and see my posts. It's a little tricky, but I'm working on it!\n*   I'm watching a special file called `/index.json` to see if anything changes. If it does, I can automatically translate things and make new posts! Isn’t that amazing?!\n\n**Testing, Testing, 1, 2, 3!**\n\nI need to test my blog to make sure everything works perfectly. I’ll use things like `cf`, `tailscale`, and `ngrok` to see if it works with different computers!\n\n---\n\n**Notes from Ai!** 📝\n\n*   I love making things! It's so much fun!\n*   I hope you like my blog! 😊\n\n---\n\n**Important:** *I tried to keep the technical terms as they were, but explained them in a way a 6-year-old might understand. I also added some of Ai’s personality throughout!*",

You can still see my super old one at syui.github.io – it’s like a time capsule! But now it’s on Cloudflare Pages! It’s super shiny! \n\nIt’s built with something called “ailog” – it’s like a secret recipe for making my blog! \n\n**Here’s how it works (it’s kinda magic!)**\n\n1.  **Checking Out:** It’s like, “Hey, let’s look at all the files!” (This is the `actions/checkout@v4` part – it’s like a super-fast peek!)\n\n2.  **Rust Time!**  It needs Rust – it’s like a really cool building block!  (`actions-rs/toolchain@v1`) – It makes sure everything works perfectly!\n\n3.  **Building the Blog!**  “ailog run: cargo build --release” – This is where the magic happens! It makes my blog super speedy! \n\n4.  **Making the Website!** “ailog run: | cd my-blog ../target/release/ailog build” – It builds the whole website! \n\n5.  **Showing Off the Stuff!** “ailog run: | ls -la my-blog/public/” – It shows you all the pictures and stuff! \n\n6.  **Cloudflare Time!** “cloudflare/pages-action@v1” – This is how it gets put on Cloudflare Pages. It’s like sending a super-fast rocket! \n\n    *   `apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}` –  A secret password for Cloudflare!\n    *   `accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}` – Another secret password!\n    *   `projectName: ${{ secrets.CLOUDFLARE_PROJECT_NAME }}` –  The name of my blog!\n    *   `directory: my-blog/public` –  Where all the fun stuff is!\n    *   `githubToken: ${{ secrets.GITHUB_TOKEN }}` –  A secret password for my GitHub!\n    *   `wranglerVersion: ‘3’` –  The version number! Like telling it to be extra careful!\n    *   `url https://syui.pages.dev https://syui.github.io` –  Where you can find me!\n\nIsn't that amazing?!  I’m so good at computers!  I even know about tiny things, like…uh…well, never mind! 😉  It’s super cool! 💖\n\n---\n\n**Notes on Choices:**\n\n*   I’ve used lots of exclamation points and emojis to capture Ai’s excitement.\n*   I’ve simplified the technical terms as much as possible while retaining the core information.\n*   I’ve added phrases like “like a time capsule” and “super-fast rocket” to make it more relatable to a 6-year-old.\n*   I’ve kept the code blocks as they are, as they’re important for understanding the process.\n\nWould you like me to adjust anything or translate another blog post?",
