-## 主要な技術スタック
+### 完成済み機能
+- ✅ **基本カード生成**: ai.bot統合での1日1回取得
+- ✅ **atproto連携**: mention機能
+- ✅ **MCP統合**: ai.gptからの操作
 
-### バックエンド
+### 開発中機能
-- **言語**: Python 3.13
+- 🔧 **iOS app**: SwiftUI実装
-- **フレームワーク**: FastAPI + fastapi-mcp
+- 🔧 **Web UI**: React実装  
-- **データベース**: SQLite (開発) / PostgreSQL (本番予定)
+- 🔧 **独立API**: FastAPI server
-- **ORM**: SQLAlchemy 2.0
 
-### フロントエンド
+### 将来機能
-- **iOS**: Swift 5.9 + SwiftUI
+- 📋 **OAuth 2.1**: 不正防止強化
-- **Web**: React + TypeScript + Vite
+- 📋 **画像最適化**: Cloudflare Pages
-- **スタイリング**: CSS Modules
+- 📋 **ゲーム拡張**: トレード・デッキ戦略
 
-## 現在の課題と制約
+## ai.botからの移行詳細
 
-### 依存関係の問題
+### 現在のai.bot実装
-1. **atproto**: `SessionString` APIが変更されたため一部機能無効化
+- **Rust製**: seahorse CLI framework
-2. **supabase**: httpxバージョン競合で無効化
+- **atproto連携**: mention機能でカード配布
-3. **PostgreSQL**: ネイティブ拡張のコンパイル問題でSQLite使用中
+- **日次制限**: 1アカウント1日1回取得
+- **自動生成**: AI絵画（Leonardo.AI + Stable Diffusion）
 
-### 回避策
+### 独立化の理由
-- atproto機能はモック実装で代替
+- **iOS展開**: モバイルアプリでの独立した体験
-- データベースはSQLiteで開発継続
+- **ゲーム拡張**: デッキ構築・バトル機能の追加
-- 本番環境ではDockerでPostgreSQL使用予定
+- **データ主権**: ユーザーによる完全なデータ所有
+- **スケーラビリティ**: サーバー負荷分散
 
-## API仕様
+## 技術的課題と解決策
 
-### MCP Tools (9個)
+### データ改ざん防止
-1. **get_user_cards(did: str)** - ユーザーのカード一覧取得
+- **短期**: MCP serverによる検証
-2. **draw_card(did: str, is_paid: bool)** - ガチャでカード取得
+- **中期**: OAuth 2.1 scope実装待ち
-3. **get_card_details(card_id: int)** - カード詳細情報
+- **長期**: ブロックチェーン的整合性チェック
-4. **analyze_card_collection(did: str)** - コレクション分析
-5. **get_unique_registry()** - ユニークカード登録状況
-6. **sync_cards_atproto(did: str)** - atproto同期（無効化中）
-7. **get_gacha_stats()** - ガチャ統計情報
 
-### REST API
+### スケーラビリティ
-- `/api/v1/cards/*` - カード管理
+- **画像配信**: Cloudflare Pages活用
-- `/api/v1/auth/*` - 認証（モック実装）
+- **API負荷**: FastAPIによる高速処理
-- `/api/v1/sync/*` - 同期機能
+- **データ保存**: atproto分散ストレージ
 
-## 今後の開発予定
