 # ai.card
 
-atprotoベースのカードゲームシステム
+🎴 atproto基盤カードゲームシステム × 🧠 ai.gpt AI統合
 
 ## 概要
 
 ai.cardは、ユーザーがデータを所有する分散型カードゲームです。
-- atprotoアカウントと連携
-- データはユーザーのPDSに保存
-- yui-systemによるuniqueカード実装
-- iOS/Web/APIの統合プロジェクト
+- 🤖 **AI統合**: ai.gpt MCPサーバー経由でAI機能拡張
+- 🔗 **atproto連携**: 分散SNSとのデータ同期
+- 📱 **クロスプラットフォーム**: iOS/Web統合クライアント
+- 🎯 **yui-system**: 個人の唯一性を保証するユニークカード実装
+
+## アーキテクチャ
+
+### 基本構成(ai.card独立動作)
+```
+iOS/Web Client

+    ↓
+SQLite/PostgreSQL + atproto PDS
+```
+
+### AI拡張構成(オプション)
+```
+iOS/Web Client
+    ↓ HTTP API (基本機能)

+- **MCP統合**: オプションでai.gpt連携
+- **データベース**: SQLite (開発) / PostgreSQL (本番)
+- **認証**: atproto OAuth 2.1 + レガシーアプリパスワード
+
+### フロントエンド
+- **Web**: React + TypeScript + Vite
+- **iOS**: Swift/SwiftUI + Combine
+- **基本機能**: ガチャ・コレクション・統計(ai.card単体)
+- **AI拡張**: コレクション分析・AI統計(ai.gpt連携時のみ)

-## 機能
+## 🧠 AI機能
 
-- カードガチャシステム
-- キラカード(0.1%)
-- uniqueカード(0.0001% - 隠し機能)
-- atprotoデータ同期
-- 改ざん防止機構
+### コレクション分析
+- **AIによる自動分析**: レアリティ分布・コレクション評価
+- **個人化推奨**: ユーザーの収集パターンに基づく提案
+- **スコアリング**: 総合的なコレクション価値算出
+
+### ガチャ統計
+- **リアルタイム統計**: 全体・個人のガチャ成功率
+- **トレンド分析**: 時系列での引き運分析
+- **活動履歴**: 最近のガチャ結果表示
 
 ## セットアップ
 
-### API
+### 基本セットアップ(ai.card単体)
+
+#### 1. ai.card サーバー起動
 ```bash
-cd api
-pip install -r requirements.txt
-uvicorn app.main:app --reload
+# 自動セットアップ
+./setup_venv.sh
+
+# サーバー起動
+./start_server.sh
+# → http://localhost:8000 で起動
 ```
 
-### Web
+#### 2. Web クライアント起動
 ```bash
 cd web
 npm install
 npm run dev
+# → http://localhost:5173 で起動(基本機能利用可能)
 ```
 
+#### 3. iOS 開発
+```bash
+# Xcodeでプロジェクトを開く
+open ios/AiCard/AiCard.xcodeproj
+# → 基本機能(ガチャ・コレクション・統計)利用可能
+```
+
+### AI拡張セットアップ(オプション)
+
+#### 4. ai.gpt サーバー起動(AI機能用)
+```bash
+# ai.gptプロジェクトで実行
+cd ../
+aigpt server --port 8001
+# → http://localhost:8001 で起動
+# → AI分析・統計機能が利用可能に
+```
+
+## 🔐 atproto OAuth認証(実装完了)
+
+### OAuth 2.1 + DPoP認証システム
+
+#### 認証フロー
+1. **ユーザー認証**: Blueskyハンドル入力 (例: syui.ai)
+2. **OAuth認証**: BrowserOAuthClient による認証リダイレクト
+3. **セッション管理**: DPoP保護されたトークンでセキュア認証
+4. **Handle表示**: DIDからHandleの自動解決
+
+#### 実装詳細
+```typescript
+// OAuth設定
+const oauthClient = await BrowserOAuthClient.load({
+  clientId: clientId,
+  handleResolver: 'https://bsky.social',
+});
+
+// 認証実行(重要: transition:genericスコープが必須)
+const authUrl = await this.oauthClient.authorize(handle, {
+  scope: 'atproto transition:generic',  // カスタムコレクション用
+});
+
+// セッション取得
+const result = await oauthClient.init();
+const agent = new Agent(result.session);  // 公式推奨方法
+```
+
+#### カスタムコレクション対応
+- **コレクション**: `ai.card.box` 
+- **必要スコープ**: `transition:generic`(カスタムレコードタイプ用)
+- **レコード例**: 
+```json
+{
+  "$type": "ai.card.box",
+  "cards": [...],
+  "total_cards": 25,
+  "updated_at": "2025-01-06T..."
+}
+```
+
+#### 確認方法
+```bash
+# atproto レコード確認
+curl -sL "https://bsky.social/xrpc/com.atproto.repo.listRecords?repo=syui.ai&collection=ai.card.box"
+```
+
+### データ主権の実現
+- **ユーザーがデータを所有**: atproto networkでレコード管理
+- **分散型アーキテクチャ**: 中央集権的サーバーに依存しない
+- **相互運用性**: 他のatproto対応アプリとのデータ共有可能
+
+## 使い方
+
+### Web アプリケーション
+
+#### 基本機能(ai.card単体)
+1. **ガチャ**: 通常/プレミアムガチャでカード取得
+2. **コレクション**: 保有カード一覧・詳細表示
+3. **📊 統計**: ガチャ統計・レアリティ分布
+
+#### AI拡張機能(ai.gpt連携時)
+4. **🧠 AI分析**: コレクション分析・推奨システム
+5. **📊 統計 (AI強化)**: 高度な統計・トレンド分析
+
+### iOS アプリケーション
+- Web版と同等の機能をネイティブUIで提供
+- SwiftUI + Combine による reactive UI
+- ai.card独立動作 + オプションでai.gpt AI機能
+

+## トラブルシューティング
+
+### OAuth認証エラー
+
+#### `Missing required scope: transition:generic`
+```typescript
+// 解決方法: スコープに transition:generic を追加
+const authUrl = await this.oauthClient.authorize(handle, {
+  scope: 'atproto transition:generic',  // ✅ 正しい
+  // scope: 'atproto',  // ❌ 不十分
+});
+```
+
+#### Handle が "unknown" と表示される
+```typescript
+// 原因: BrowserOAuthClient の使用方法が間違っている
+// 解決方法: sessionオブジェクトを直接Agentに渡す
+const agent = new Agent(result.session);  // ✅ 公式推奨
+// new Agent({service: '...', fetch: session.dpopFetch});  // ❌ 非推奨
+```
+
+#### カスタムコレクションへの書き込みエラー
+```bash
+# 確認: OAuth スコープが正しく設定されているか
+# ブラウザコンソールで確認:
+console.log(atprotoOAuthService.getSession());
+# → scope: "atproto transition:generic" が含まれているか確認
+```
+
+### ai.gpt連携エラー
+```bash
+# ai.gptサーバーが起動しているか確認
+curl http://localhost:8001/health
+
+# ai.cardサーバーが起動しているか確認
+curl http://localhost:8000/health
+```
+
+### データベースエラー
+```bash
+# データベース初期化
+cd api
+~/.config/syui/ai/card/venv/bin/python init_db.py
+```
+
+### atproto データ確認
+```bash
+# バックアップされたレコードを確認
+curl -sL "https://bsky.social/xrpc/com.atproto.repo.listRecords?repo={YOUR_HANDLE}&collection=ai.card.box"
+
+# レコード詳細取得
+curl -sL "https://bsky.social/xrpc/com.atproto.repo.getRecord?repo={YOUR_HANDLE}&collection=ai.card.box&rkey=self"
+```
