+- **SSOT** (Single Source of Truth): All data stored in `~/.cc-switch/cc-switch.db` (SQLite)
+- **Dual-layer Storage**: SQLite for syncable data, JSON for device-level settings
 - **Dual-way Sync**: Write to live files on switch, backfill from live when editing active provider
 - **Atomic Writes**: Temp file + rename pattern prevents config corruption
-- **Concurrency Safe**: RwLock with scoped guards avoids deadlocks
+- **Concurrency Safe**: Mutex-protected database connection avoids race conditions
-- **Layered Architecture**: Clear separation (Commands → Services → Models)

+  - Codex: `~/.codex/AGENTS.md`
+  - Gemini: `~/.gemini/GEMINI.md`
+- **保護機構**: 切り替え前に現在の内容を自動保存し、手動変更を保持
+
+### 設定ファイルパス
+
+**Claude Code**
+
+- ライブ設定: `~/.claude/settings.json`（または `claude.json`）
+- API キーフィールド: `env.ANTHROPIC_AUTH_TOKEN` または `env.ANTHROPIC_API_KEY`
+- MCP サーバー: `~/.claude.json` → `mcpServers`
+
+**Codex**
+
+- ライブ設定: `~/.codex/auth.json`（必須）+ `config.toml`（任意）
+- API キーフィールド: `auth.json` 内の `OPENAI_API_KEY`
+- MCP サーバー: `~/.codex/config.toml` → `[mcp_servers]` テーブル
+
+**Gemini**
+
+- ライブ設定: `~/.gemini/.env`（API キー）+ `~/.gemini/settings.json`（認証モード）
+- API キーフィールド: `.env` 内の `GEMINI_API_KEY` または `GOOGLE_GEMINI_API_KEY`
+- 環境変数: `GOOGLE_GEMINI_BASE_URL`、`GEMINI_MODEL` などをサポート
+- MCP サーバー: `~/.gemini/settings.json` → `mcpServers`
+- トレイでのクイックスイッチ: プロバイダ切り替えごとに `~/.gemini/.env` を書き換えるため Gemini CLI の再起動は不要
+
+**CC Switch 保存先 (v3.8.0 新アーキテクチャ)**
+
+- データベース (SSOT): `~/.cc-switch/cc-switch.db`（SQLite。プロバイダ、MCP、Prompts、Skills を保存）
+- ローカル設定: `~/.cc-switch/settings.json`（デバイスレベル設定）
+- バックアップ: `~/.cc-switch/backups/`（自動ローテーション、最新 10 件を保持）
+
+### クラウド同期の設定
+
+1. 設定 → 「Custom Configuration Directory」へ進む
+2. クラウド同期フォルダ（Dropbox、OneDrive、iCloud など）を選択
+3. アプリを再起動して反映
+4. 他のデバイスでも同じフォルダを指定すればクロスデバイス同期が有効に
+
+> **補足**: 初回起動時に既存の Claude/Codex 設定をデフォルトプロバイダとして自動インポートします。
+

+```
+
+**コア設計パターン**
+
+- **SSOT** (Single Source of Truth): すべてのデータを `~/.cc-switch/cc-switch.db`（SQLite）に集約
+- **二層ストレージ**: 同期データは SQLite、デバイスデータは JSON
+- **双方向同期**: 切り替え時はライブファイルへ書き込み、編集時はアクティブプロバイダから逆同期
+- **アトミック書き込み**: 一時ファイル + rename パターンで設定破損を防止
+- **並行安全**: Mutex で保護された DB 接続でレースを防ぐ
+- **レイヤードアーキテクチャ**: Commands → Services → DAO → Database を明確に分離
+
+**主要コンポーネント**
+
+- **ProviderService**: プロバイダの CRUD、切り替え、バックフィル、ソート
+- **McpService**: MCP サーバー管理、インポート/エクスポート、ライブファイル同期
+- **ConfigService**: 設定のインポート/エクスポート、バックアップローテーション
+- **SpeedtestService**: API エンドポイントの遅延計測
+
+**v3.6 リファクタリング**
+
+- バックエンド: エラーハンドリング → コマンド分割 → テスト → サービス層 → 並行性の 5 フェーズ
+- フロントエンド: テスト基盤 → hooks → コンポーネント → クリーンアップの 4 ステージ
+- テスト: hooks 100% カバレッジ + 統合テスト（vitest + MSW）

+# CC Switch 代理功能使用指南
+
+## 功能介绍
+
+CC Switch 的代理功能是一个本地 HTTP 代理服务器，可以统一管理 Claude Code、Codex 和 Gemini CLI 的 API 请求。主要特性包括：
+
+- **统一代理入口** - 所有 CLI 应用的请求通过本地代理转发
+- **自动故障转移** - 当前供应商故障时自动切换到备用供应商
+- **按应用控制** - 可独立控制每个应用是否启用代理
+- **配置保护** - 自动备份原始配置，停止代理时安全恢复
+
+## 快速开始
+
+### 1. 启动代理
+
+在 CC Switch 主界面，点击右上角的 **Proxy** 按钮，可以看到代理控制面板。
+
+点击 **启动代理** 按钮启动本地代理服务器。代理默认监听 `127.0.0.1:15721`。
+
+### 2. 启用应用接管
+
+代理启动后，你可以选择让哪些应用的请求通过代理：
+
+- **Claude** - 接管 Claude Code 的 API 请求
+- **Codex** - 接管 Codex CLI 的 API 请求
+- **Gemini** - 接管 Gemini CLI 的 API 请求
+
+点击对应应用的开关即可启用/禁用接管。
+
+> **注意**：启用接管后，CC Switch 会自动修改对应应用的配置文件，将 API 端点指向本地代理。原始配置会被安全备份。
+
+### 3. 正常使用 CLI
+
+启用接管后，你可以正常使用各个 CLI 工具。所有请求都会经过 CC Switch 代理转发到配置的供应商。
+
+### 4. 停止代理
+
+当你不再需要代理时，点击 **停止代理** 按钮。CC Switch 会：
+
+1. 安全关闭代理服务器
+2. 自动恢复所有应用的原始配置
+3. 清除代理状态
+
+## 自动故障转移
+
+### 工作原理
+
+代理功能内置了智能故障转移机制：
+
+1. **健康监控** - 实时监控每个供应商的响应状态
+2. **熔断器** - 连续失败 5 次后触发熔断，暂停使用该供应商
+3. **自动切换** - 熔断后自动切换到列表中的下一个供应商
+4. **自动恢复** - 30 秒后尝试恢复熔断的供应商
+
+### 配置故障转移
+
+要使用故障转移功能，你需要：
+
+1. 在对应应用下添加多个供应商（至少 2 个）
+2. 启动代理并启用接管
+3. 当主供应商故障时，代理会自动切换到备用供应商
+
+### 健康状态指示
+
+在供应商卡片上可以看到健康状态指示：
+
+- **绿色** - 供应商正常
+- **红色** - 供应商故障/熔断中
+- **灰色** - 未使用代理或未检测
+
+## 按应用接管
+
+v3.9.0 新增了按应用分粒度控制功能：
+
+- 你可以只接管 Claude，而让 Codex 使用原始配置
+- 每个应用的接管状态独立管理
+- 启用/禁用不会影响其他应用
+
+### 接管状态检测
+
+CC Switch 通过检测配置备份来判断接管状态：
+
+- 存在备份 = 已接管
+- 无备份 = 未接管
+
+这确保了即使 CC Switch 异常退出，重新启动后也能正确识别状态。
+
+## 代理配置
+
+在代理面板中，你可以配置以下参数：
+
+| 参数 | 默认值 | 说明 |
+|------|--------|------|
+| 监听地址 | 127.0.0.1 | 代理服务器绑定地址 |
+| 监听端口 | 15721 | 代理服务器端口 |
+| 最大重试 | 3 | 请求失败时的最大重试次数 |
+| 请求超时 | 120 秒 | 单个请求的超时时间 |
+| 启用日志 | 是 | 是否记录请求日志 |
+
+## 常见问题
+
+### Q: 代理启动失败，提示端口被占用？
+
+A: 默认端口 15721 可能被其他程序占用。你可以：
+- 关闭占用该端口的程序
+- 在代理配置中修改端口号
+
+### Q: 启用接管后 CLI 无法使用？
+
+A: 请检查：
+1. 代理服务器是否正常运行（查看代理面板状态）
+2. 供应商配置是否正确（API Key 等）
+3. 网络连接是否正常
+
+### Q: 如何恢复原始配置？
+
+A: 点击 **停止代理** 按钮，CC Switch 会自动恢复所有应用的原始配置。
+
+如果 CC Switch 异常退出，重新启动后会检测到之前的备份，你可以：
+- 点击停止代理来恢复配置
+- 或继续使用代理功能
+
+### Q: 故障转移没有生效？
+
+A: 请确保：
+1. 配置了至少 2 个供应商
+2. 代理已启动且接管已启用
+3. 故障转移只在代理模式下工作
+
+### Q: 代理会影响性能吗？
+
+A: 本地代理的延迟开销非常小（通常 < 1ms）。但如果启用了请求日志，在高频请求场景下可能会有少量性能影响。
+
+## 技术细节
+
+### 配置文件位置
+
+启用接管后，CC Switch 会修改以下配置文件：
+
+| 应用 | 配置文件 | 修改内容 |
+|------|----------|----------|
+| Claude | `~/.claude/settings.json` | `apiBaseUrl` 指向代理 |
+| Codex | `~/.codex/config.toml` | `[api] baseUrl` 指向代理 |
+| Gemini | `~/.gemini/.env` | `GEMINI_BASE_URL` 指向代理 |
+
+原始配置备份在 CC Switch 数据库中，停止代理时自动恢复。
+
+### 代理模式
+
+代理服务器运行在接管模式下，会：
+
+1. 接收来自 CLI 的 HTTPS 请求
+2. 根据当前供应商配置转发到真实 API 端点
+3. 返回响应给 CLI
+4. 记录请求日志和健康状态
+
+### 数据库表
+
+代理功能使用以下数据库表：
+
+- `proxy_config` - 代理配置
+- `provider_health` - 供应商健康状态
+- `proxy_request_logs` - 请求日志
+- `circuit_breaker_config` - 熔断器配置
+- `proxy_live_backup` - Live 配置备份

+
+**[中文版 →](release-note-v3.8.0-zh.md) | [日本語版 →](release-note-v3.8.0-ja.md)**
+
+---
+
+## Overview
+
+CC Switch v3.8.0 is a major architectural upgrade that restructures the data persistence layer and user interface, laying the foundation for future cloud sync and local proxy features.
+
+**Release Date**: 2025-11-28
+**Commits**: 51 commits since v3.7.1
+**Code Changes**: 207 files, +17,297 / -6,870 lines
+
+---
+
+## Major Updates
+
+### Persistence Architecture Upgrade
+
+Migrated from single JSON file storage to SQLite + JSON dual-layer architecture for hierarchical data management.
+
+**Architecture Changes**:
+
+```
+v3.7.x (Old)                     v3.8.0 (New)

+                                 └─────────────────────────────────┘
+```
+
+**Dual-layer Structure Design**:
+
+| Layer      | Storage | Data Types                      | Sync Strategy   |
+| ---------- | ------- | ------------------------------- | --------------- |
+| Cloud Sync | SQLite  | Providers, MCP, Prompts, Skills | Future syncable |
+| Device     | JSON    | Window state, local paths       | Stays local     |
+
+**Technical Implementation**:
+
+- **Schema Version Management** - Supports database structure upgrade migrations
+- **SQL Import/Export** - `backup.rs` supports SQL dump for cloud storage
+- **Transaction Support** - SQLite native transactions ensure data consistency
+- **Auto Migration** - Automatically migrates from `config.json` on first launch
+
+**Modular Refactoring**:
+
+```
+database/
+├── mod.rs              Core Database struct and initialization
+├── schema.rs           Table definitions, schema version migrations
+├── backup.rs           SQL import/export, binary snapshot backup
+├── migration.rs        JSON → SQLite data migration engine
+└── dao/                Data Access Object layer
+    ├── providers.rs    Provider CRUD
+    ├── mcp.rs          MCP server CRUD
+    ├── prompts.rs      Prompts CRUD
+    ├── skills.rs       Skills CRUD
+    └── settings.rs     Key-value settings storage

+
+## Bug Fixes
+
+### Critical Fixes
+
+**Custom Endpoints Lost Issue**
+
+Fixed an issue where custom request URLs were unexpectedly lost when updating providers.

+## Migration Guide
+
+### Upgrading from v3.7.x
+
+**Auto Migration** - Executes automatically on first launch:
+
+1. Detects if `config.json` exists
+2. Migrates all data to SQLite within a transaction
+3. Migrates device-level settings to `settings.json`
+4. Shows migration success notification
+
+**Data Safety**:
+
+- Original `config.json` file is preserved (not deleted)
+- Error dialog displayed on migration failure, `config.json` preserved
+- Supports Dry-run mode to verify migration logic

+## 📐 技术架构
+
+### 数据结构设计
+
+#### 新增：McpApps（应用启用状态）
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, Default, PartialEq)]
+pub struct McpApps {
+    pub claude: bool,
+    pub codex: bool,
+    pub gemini: bool,
+}
+```
+
+#### 更新：McpServer（统一服务器定义）
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct McpServer {
+    pub id: String,
+    pub name: String,
+    pub server: serde_json::Value,  // 连接配置（stdio/http）
+    pub apps: McpApps,               // 新增：标记应用到哪些客户端
+    pub description: Option<String>,
+    pub homepage: Option<String>,
+    pub docs: Option<String>,
+    pub tags: Vec<String>,
+}
+```
+
+#### 更新：McpRoot（新旧结构并存）
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, Default)]
+pub struct McpRoot {
+    // v3.7.0 新结构
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub servers: Option<HashMap<String, McpServer>>,
+
+    // v3.6.x 旧结构（保留用于迁移）
+    #[serde(default, skip_serializing_if = "McpConfig::is_empty")]
+    pub claude: McpConfig,
+    #[serde(default, skip_serializing_if = "McpConfig::is_empty")]
+    pub codex: McpConfig,
+    #[serde(default, skip_serializing_if = "McpConfig::is_empty")]
+    pub gemini: McpConfig,
+}

+
+**迁移逻辑**：
+1. 检测 `mcp.servers` 是否存在
+2. 若不存在，从 `mcp.claude/codex/gemini.servers` 收集所有服务器
+3. 合并同 id 服务器的 apps 字段
+4. 清空旧结构字段
+5. 保存配置（自动触发）

+# Flatpak Build Guide
+
+This directory contains the Flatpak manifest (`com.ccswitch.desktop`) for CC Switch, used to convert the generated `.deb` artifact into an installable `.flatpak` package via CI or local builds.
+
+## Dependencies
+
+- `flatpak`
+- `flatpak-builder`
+- Flathub remote (for installing `org.gnome.Platform//46` runtime)
+
+For Ubuntu/Debian:
+
+```bash
+sudo apt install flatpak flatpak-builder
+flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
+flatpak install -y --user flathub org.gnome.Platform//46 org.gnome.Sdk//46
+```
+
+## Local Build (Generate .flatpak from .deb)
+
+1) Build the deb on Linux first:
+
+```bash
+pnpm tauri build -- --bundles deb
+```
+
+2) Copy the generated deb to this directory:
+
+```bash
+cp "$(find src-tauri/target/release/bundle -name '*.deb' | head -n 1)" flatpak/cc-switch.deb
+```
+
+3) Build the local Flatpak repository and export the `.flatpak`:
+
+```bash
+flatpak-builder --force-clean --user --disable-cache --repo flatpak-repo flatpak-build flatpak/com.ccswitch.desktop.yml
+flatpak build-bundle --runtime-repo=https://flathub.org/repo/flathub.flatpakrepo flatpak-repo CC-Switch-Linux.flatpak com.ccswitch.desktop
+```
+
+4) Install and run:
+
+```bash
+flatpak install --user ./CC-Switch-Linux.flatpak
+flatpak run com.ccswitch.desktop
+```
+
+## Permissions Note
+
+The current manifest uses `--filesystem=home` by default for "download and run" convenience, allowing the app to directly read/write CLI configuration files and app data on the host (and supporting the "directory override" feature).
+
+If you prefer minimal permissions (e.g., for Flathub submission or security concerns), you can replace `--filesystem=home` in `flatpak/com.ccswitch.desktop.yml` with more precise grants:
+
+```yaml
+  - --filesystem=~/.cc-switch:create
+  - --filesystem=~/.claude:create
+  - --filesystem=~/.claude.json
+  - --filesystem=~/.codex:create
+  - --filesystem=~/.gemini:create
+```
+
+Note: Flatpak's `:create` modifier only works with directories, not files. Therefore, `~/.claude.json` cannot use `:create`. If this file doesn't exist on the user's machine, the app may not be able to create it with restricted permissions. Users should either run Claude Code once to generate it, or manually create an empty JSON file (content: `{}`).
+
+If you plan to publish on Flathub or want stricter permission control, adjust the `finish-args` in `flatpak/com.ccswitch.desktop.yml` accordingly.
