fix(tests): correct error type assertions in proxy DAO tests

The tests expected AppError::InvalidInput but the DAO functions use AppError::localized() which returns AppError::Localized variant. Updated assertions to match the correct error type with key validation.

 - Configuration file handling
-
-## [Unreleased]
-
-### ⚠️ Breaking Changes
-
- **Runtime auto-migration from v1 to v2 config format has been removed**
-  - `MultiAppConfig::load()` no longer automatically migrates v1 configs
-  - When a v1 config is detected, the app now returns a clear error with migration instructions
-  - **Migration path**: Install v3.2.x to perform one-time auto-migration, OR manually edit `~/.cc-switch/config.json` to v2 format
-  - **Rationale**: Separates concerns (load() should be read-only), fail-fast principle, simplifies maintenance
-  - Related: `app_config.rs` (v1 detection improved with structural analysis), `app_config_load.rs` (comprehensive test coverage added)
-
- **Legacy v1 copy file migration logic has been removed**
-  - Removed entire `migration.rs` module (435 lines) that handled one-time migration from v3.1.0 to v3.2.0
-  - No longer scans/merges legacy copy files (`settings-*.json`, `auth-*.json`, `config-*.toml`)
-  - No longer archives copy files or performs automatic deduplication
-  - **Migration path**: Users upgrading from v3.1.0 must first upgrade to v3.2.x to automatically migrate their configurations
-  - **Benefits**: Improved startup performance (no file scanning), reduced code complexity, cleaner codebase
-
- **Tauri commands now only accept `app` parameter**
-  - Removed legacy `app_type`/`appType` compatibility paths
-  - Explicit error with available values when unknown `app` is provided
-
-### 🔧 Improvements
-
- Unified `AppType` parsing: centralized to `FromStr` implementation, command layer no longer implements separate `parse_app()`, reducing code duplication and drift
- Localized and user-friendly error messages: returns bilingual (Chinese/English) hints for unsupported `app` values with a list of available options
- Simplified startup logic: Only ensures config structure exists, no migration overhead
-
-### 🧪 Tests
-
- Added unit tests covering `AppType::from_str`: case sensitivity, whitespace trimming, unknown value error messages
- Added comprehensive config loading tests:
-  - `load_v1_config_returns_error_and_does_not_write`
-  - `load_v1_with_extra_version_still_treated_as_v1`
-  - `load_invalid_json_returns_parse_error_and_does_not_write`
-  - `load_valid_v2_config_succeeds`

+# OpenCode 第四应用支持实现计划
+
+> **范围说明**：本计划暂不包含统一供应商（UniversalProvider）对 OpenCode 的支持，以降低初期实现复杂度。
+
+## 概述
+
+为 CC Switch 添加 OpenCode 支持，这是第四个受管理的 CLI 应用。OpenCode 的核心差异在于采用**累加式**供应商管理（多供应商共存，应用内热切换），而非现有三应用的**替换式**管理。
+
+## 关键设计决策
+
+| 特性 | Claude/Codex/Gemini | OpenCode |
+|------|---------------------|----------|
+| 供应商模式 | 替换式（单一活跃） | 累加式（多供应商共存） |
+| UI 按钮 | 启用/切换 | 添加/删除 |
+| is_current | 需要 | 不需要 |
+| 代理/故障转移 | 支持 | 不支持 |
+| API 格式字段 | 无 | 需要（npm 包名） |
+| 配置文件 | 各自独立 | `~/.config/opencode/opencode.json` |
+
+## 配置文件格式
+
+### 供应商配置
+```json
+{
+  "$schema": "https://opencode.ai/config.json",
+  "provider": {
+    "provider-id": {
+      "npm": "@ai-sdk/openai-compatible",
+      "name": "Provider Name",
+      "options": {
+        "baseURL": "https://api.example.com/v1",
+        "apiKey": "{env:API_KEY}"
+      },
+      "models": {
+        "model-id": { "name": "Model Name" }
+      }
+    }
+  }
+}
+```
+
+### MCP 配置
+```json
+{
+  "mcp": {
+    "remote-server": {
+      "type": "remote",
+      "url": "https://example.com/mcp",
+      "enabled": true
+    },
+    "local-server": {
+      "type": "local",
+      "command": ["npx", "-y", "my-mcp-command"],
+      "enabled": true,
+      "environment": { "KEY": "value" }
+    }
+  }
+}
+```
+
+---
+
+## 实现步骤
+
+### Phase 1: 后端数据结构扩展
+
+#### 1.1 AppType 枚举扩展
+**文件**: `src-tauri/src/app_config.rs`
+
+```rust
+pub enum AppType {
+    Claude,
+    Codex,
+    Gemini,
+    OpenCode,  // 新增
+}
+```
+
+#### 1.2 McpApps / SkillApps 扩展
+**文件**: `src-tauri/src/app_config.rs`
+
+```rust
+pub struct McpApps {
+    pub claude: bool,
+    pub codex: bool,
+    pub gemini: bool,
+    pub opencode: bool,  // 新增
+}
+
+pub struct SkillApps {
+    pub claude: bool,
+    pub codex: bool,
+    pub gemini: bool,
+    pub opencode: bool,  // 新增
+}
+```
+
+#### 1.3 数据库 Schema 迁移
+**文件**: `src-tauri/src/database/schema.rs`
+
+- `SCHEMA_VERSION` 递增
+- 添加迁移：
+  ```sql
+  ALTER TABLE mcp_servers ADD COLUMN enabled_opencode BOOLEAN NOT NULL DEFAULT 0;
+  ALTER TABLE skills ADD COLUMN enabled_opencode BOOLEAN NOT NULL DEFAULT 0;
+  ```
+
+### Phase 2: OpenCode 供应商数据结构
+
+#### 2.1 OpenCode 专属配置结构
+**文件**: `src-tauri/src/provider.rs`（或新建 `opencode_provider.rs`）
+
+```rust
+/// OpenCode 供应商的 settings_config 结构
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct OpenCodeProviderConfig {
+    /// AI SDK 包名，如 "@ai-sdk/openai-compatible"
+    pub npm: String,
+    /// 供应商选项
+    pub options: OpenCodeProviderOptions,
+    /// 模型定义
+    pub models: HashMap<String, OpenCodeModel>,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct OpenCodeProviderOptions {
+    #[serde(rename = "baseURL", skip_serializing_if = "Option::is_none")]
+    pub base_url: Option<String>,
+    #[serde(rename = "apiKey", skip_serializing_if = "Option::is_none")]
+    pub api_key: Option<String>,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub headers: Option<HashMap<String, String>>,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct OpenCodeModel {
+    pub name: String,
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub limit: Option<OpenCodeModelLimit>,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct OpenCodeModelLimit {
+    pub context: Option<u64>,
+    pub output: Option<u64>,
+}
+```
+
+### Phase 3: OpenCode Live 配置读写
+
+#### 3.1 新建 OpenCode 配置模块
+**文件**: `src-tauri/src/opencode_config.rs`
+
+核心功能：
+- `get_opencode_config_path()` → `~/.config/opencode/opencode.json`
+- `read_opencode_config()` → 读取整个配置文件
+- `write_opencode_config()` → 原子写入配置文件
+- `get_providers()` → 获取 `provider` 对象
+- `set_provider(id, config)` → 添加/更新供应商
+- `remove_provider(id)` → 删除供应商
+- `get_mcp_servers()` → 获取 `mcp` 对象
+- `set_mcp_server(id, config)` → 添加/更新 MCP 服务器
+- `remove_mcp_server(id)` → 删除 MCP 服务器
+
+### Phase 4: MCP 同步模块
+
+#### 4.1 新建 OpenCode MCP 同步
+**文件**: `src-tauri/src/mcp/opencode.rs`
+
+```rust
+/// 同步所有 enabled_opencode=true 的服务器到 OpenCode 配置
+pub fn sync_enabled_to_opencode(config: &MultiAppConfig) -> Result<(), AppError>
+
+/// 同步单个服务器
+pub fn sync_single_server_to_opencode(
+    config: &MultiAppConfig,
+    id: &str,
+    server_spec: &Value
+) -> Result<(), AppError>
+
+/// 从 OpenCode 配置移除服务器
+pub fn remove_server_from_opencode(id: &str) -> Result<(), AppError>
+
+/// 从 OpenCode 配置导入服务器
+pub fn import_from_opencode(config: &mut MultiAppConfig) -> Result<usize, AppError>
+```
+
+**格式转换**：
+| CC Switch 统一格式 | OpenCode 格式 |
+|-------------------|---------------|
+| `type: "stdio"` | `type: "local"` |
+| `command` + `args` | `command: [cmd, ...args]` |
+| `env` | `environment` |
+| `type: "sse"/"http"` | `type: "remote"` |
+| `url` | `url` |
+
+### Phase 5: 供应商服务层
+
+#### 5.1 OpenCode 供应商服务
+**文件**: `src-tauri/src/services/provider/opencode.rs`
+
+核心方法：
+```rust
+/// 获取所有 OpenCode 供应商
+pub fn list(state: &AppState) -> Result<IndexMap<String, Provider>, AppError>
+
+/// 添加供应商（同时写入 live 配置）
+pub fn add(state: &AppState, provider: Provider) -> Result<bool, AppError>
+
+/// 更新供应商
+pub fn update(state: &AppState, provider: Provider) -> Result<bool, AppError>
+
+/// 删除供应商（同时从 live 配置移除）
+pub fn delete(state: &AppState, id: &str) -> Result<(), AppError>
+
+/// 从 live 配置导入供应商到数据库
+pub fn import_from_live(state: &AppState) -> Result<usize, AppError>
+```
+
+**关键差异**：
+- 不需要 `switch()` 方法
+- 不需要 `is_current` 管理
+- `add()` 自动写入 live
+- `delete()` 自动从 live 移除
+
+### Phase 6: Tauri 命令扩展
+
+#### 6.1 更新现有命令
+**文件**: `src-tauri/src/commands/providers.rs`
+
+- 所有命令支持 `app_type = "opencode"`
+- OpenCode 特定逻辑分支
+
+#### 6.2 新增 OpenCode 专属命令（如需要）
+```rust
+#[tauri::command]
+pub async fn opencode_sync_all_providers(state: State<'_, AppState>) -> Result<(), AppError>
+```
+
+### Phase 7: 前端类型定义
+
+#### 7.1 TypeScript 类型扩展
+**文件**: `src/types.ts`
+
+```typescript
+// AppId 扩展
+type AppId = "claude" | "codex" | "gemini" | "opencode";
+
+// OpenCode 专属配置
+interface OpenCodeProviderConfig {
+  npm: string;  // AI SDK 包名
+  options: {
+    baseURL?: string;
+    apiKey?: string;
+    headers?: Record<string, string>;
+  };
+  models: Record<string, OpenCodeModel>;
+}
+
+interface OpenCodeModel {
+  name: string;
+  limit?: {
+    context?: number;
+    output?: number;
+  };
+}
+```
+
+#### 7.2 MCP 应用状态扩展
+**文件**: `src/types.ts`
+
+```typescript
+interface McpApps {
+  claude: boolean;
+  codex: boolean;
+  gemini: boolean;
+  opencode: boolean;  // 新增
+}
+```
+
+### Phase 8: 前端预设配置
+
+#### 8.1 新建 OpenCode 供应商预设
+**文件**: `src/config/opencodeProviderPresets.ts`
+
+```typescript
+export const opencodeProviderPresets: ProviderPreset[] = [
+  {
+    name: "OpenAI",
+    npmPackage: "@ai-sdk/openai",
+    settingsConfig: {
+      npm: "@ai-sdk/openai",
+      options: { apiKey: "{env:OPENAI_API_KEY}" },
+      models: {
+        "gpt-4o": { name: "GPT-4o" },
+        "gpt-4o-mini": { name: "GPT-4o Mini" },
+      },
+    },
+    theme: { icon: "openai", iconColor: "#00A67E" },
+  },
+  {

+      },
+      models: {},
+    },
+    isCustomTemplate: true,
+  },
+  // ... 更多预设
+];
+
+// npm 包选项
+export const opencodeNpmPackages = [
+  { value: "@ai-sdk/openai", label: "OpenAI" },
+  { value: "@ai-sdk/anthropic", label: "Anthropic" },
+  { value: "@ai-sdk/openai-compatible", label: "OpenAI Compatible" },

+  { value: "@ai-sdk/amazon-bedrock", label: "Amazon Bedrock" },
+  // ... 更多选项
+];
+```
+
+### Phase 9: 前端 UI 组件
+
+#### 9.1 OpenCode 供应商表单
+**文件**: `src/components/providers/forms/OpenCodeFormFields.tsx`
+
+新增字段：
+- npm 包选择器（下拉框 + 自定义输入）
+- options 编辑器（baseURL, apiKey, headers）
+- models 编辑器（动态添加/删除模型）
+
+#### 9.2 供应商卡片按钮适配
+**文件**: `src/components/providers/ProviderActions.tsx`
+
+```tsx
+// OpenCode 使用不同的主按钮
+if (appId === "opencode") {
+  return (
+    <Button onClick={onAdd}>
+      {isInConfig ? t("provider.removeFromConfig") : t("provider.addToConfig")}
+    </Button>
+  );
+}
+```
+
+#### 9.3 隐藏 OpenCode 不需要的功能
+
+在以下组件中检查 `appId !== "opencode"`：
+- 代理设置面板
+- 故障转移队列
+- 供应商切换逻辑
+
+### Phase 10: 国际化
+
+#### 10.1 新增翻译 Key
+**文件**: `src/locales/zh/translation.json` & `en/translation.json`
+
+```json
+{
+  "app.opencode": "OpenCode",
+  "provider.addToConfig": "添加到配置",
+  "provider.removeFromConfig": "从配置移除",
+  "provider.inConfig": "已添加",
+  "provider.npmPackage": "AI SDK 包",
+  "provider.models": "模型配置",
+  // ...
+}
+```

+
+## 验证计划
+
+### 单元测试
+1. OpenCode 配置读写测试
+2. MCP 格式转换测试（stdio ↔ local, sse ↔ remote）
+3. 供应商 CRUD 操作测试
+
+### 集成测试
+1. 添加 OpenCode 供应商 → 验证写入 `~/.config/opencode/opencode.json`
+2. 删除供应商 → 验证从配置文件移除
+3. MCP 同步测试 → 验证格式正确转换
+4. 从 live 配置导入 → 验证正确解析
+
+### 手动测试
+1. UI 流程：添加预设 → 编辑 → 删除
+2. 切换应用 Tab → OpenCode 显示正确的 UI（无代理/故障转移）
+3. 托盘菜单正确显示 OpenCode 供应商
+4. 深链接导入 OpenCode 供应商
+
+---
+
+## 风险评估
+
+1. **数据库迁移**：需要在升级时自动执行 `ALTER TABLE` 语句
+2. **配置文件冲突**：OpenCode 可能有自己的配置，需要合并而非覆盖
+3. **MCP 格式差异**：`stdio` → `local` 转换需要处理边界情况
+4. **UI 一致性**：OpenCode 的"添加/删除"模式需要与其他应用的"启用/切换"清晰区分
+
+---
+
+## 补充说明
+
+### 托盘菜单特殊处理
+
+由于 OpenCode 采用累加式管理，托盘菜单行为需要调整：
+
+- **现有三应用**：托盘菜单显示 `CheckMenuItem`（单选，切换当前供应商）
+- **OpenCode**：显示当前所有启用的供应商（普通 MenuItem，无勾选逻辑），点击打开主界面
+
+**修改文件**：`src-tauri/src/tray.rs`（`TRAY_SECTIONS` 常量）
+
+### 数据库约束更新
+
+`proxy_config` 表的 CHECK 约束需要扩展：
+```sql
+CHECK (app_type IN ('claude','codex','gemini','opencode'))
+```
+
+### Settings 结构体扩展
+
+**文件**：`src-tauri/src/settings.rs`
+
+需要添加：
+- `current_provider_opencode: Option<String>` - 对 OpenCode 可能无意义，但保持结构一致
+- `opencode_config_dir: Option<String>` - 自定义配置目录

+# CC Switch v3.9.0
+
+> Local API Proxy, Auto Failover, Universal Provider, and a more complete multi-app workflow
+
+**[中文版 →](release-note-v3.9.0-zh.md) | [日本語版 →](release-note-v3.9.0-ja.md)**
+
+---
+
+## Overview
+
+CC Switch v3.9.0 is the stable release of the v3.9 beta series (`3.9.0-1`, `3.9.0-2`, `3.9.0-3`).
+It introduces a local API proxy with per-app takeover, automatic failover, universal providers, and many stability and UX improvements across Claude Code, Codex, and Gemini CLI.
+
+**Release Date**: 2026-01-07
+
+---
+
+## Highlights
+
+- Local API Proxy for Claude Code / Codex / Gemini CLI
+- Auto Failover with circuit breaker and per-app failover queues
+- Universal Provider: one shared config synced across apps (ideal for API gateways like NewAPI)
+- Skills improvements: multi-app support, unified management with SSOT + React Query
+- Common config snippets: extract reusable snippets from the editor or the current provider
+- MCP import: import MCP servers from installed apps
+- Usage improvements: auto-refresh, cache hit/creation metrics, and timezone fixes
+- Linux packaging: RPM and Flatpak artifacts
+
+---
+
+## Major Features
+
+### Local API Proxy
+
+- Runs a local high-performance HTTP proxy server (Axum-based)
+- Supports Claude Code, Codex, and Gemini CLI with a unified proxy
+- Per-app takeover: you can independently decide which app routes through the proxy
+- Live config takeover: backs up and redirects the CLI live config to the local proxy when takeover is enabled
+- Monitoring: request logging and usage statistics for easier debugging and cost tracking
+- Error request logging: keep detailed logs for failed proxy requests to simplify debugging (#401, thanks @yovinchen)
+
+### Auto Failover (Circuit Breaker)
+
+- Automatically detects provider failures and triggers protection (circuit breaker)
+- Automatically switches to a backup provider when the current one is unhealthy
+- Tracks provider health in real time, and keeps independent failover queues per app
+- When failover is disabled, timeout/retry related settings no longer affect normal request flow
+
+### Skills Management
+
+- Multi-app Skills support for Claude Code and Codex, with smoother migration from older skill layouts (#365, #378, thanks @yovinchen)
+- Unified Skills management architecture (SSOT + React Query) for more consistent state and refresh behavior
+- Better discovery UX and performance:
+  - Skip hidden directories during discovery
+  - Faster discovery with long-lived caching for discoverable skills
+  - Clear loading indicators and more discoverable header actions (import/refresh)
+  - Fix wrong skill repo branch (#505, thanks @kjasn)
+
+### Universal Provider
+
+- Add a shared provider configuration that can sync to Claude/Codex/Gemini (#348, thanks @Calcium-Ion)
+- Designed for API gateways that support multiple protocols (e.g., NewAPI)
+- Allows per-app default model mapping under a single provider
+
+### Common Config Snippets (Claude/Codex/Gemini)
+
+- Maintain a reusable "common config" snippet and merge/append it into providers that enable it
+- New extraction workflow:
+  - Extract from the editor content (what you are currently editing)
+  - Or extract from the current active provider when the editor content is not provided
+- Codex extraction is safer:
+  - Removes provider-specific sections like `model_provider`, `model`, and the entire `model_providers` table
+  - Preserves `base_url` under `[mcp_servers.*]` so MCP configs are not accidentally broken
+
+### MCP Management
+
+- Import MCP servers from installed apps
+- Improve robustness: skip sync when the target CLI app is not installed; handle invalid Codex `config.toml` gracefully (#461, thanks @majiayu000)
+- Windows compatibility: wrap npx/npm commands with `cmd /c` for MCP export
+
+### Usage & Pricing
+
+- Usage & pricing improvements: auto-refresh, cache hit/creation metrics, timezone handling fixes, and refreshed built-in pricing table (#508, thanks @yovinchen)
+- DeepLink support: import usage query configuration via deeplink (#400, thanks @qyinter)
+- Model extraction for usage statistics (#455, thanks @yovinchen)
+- Usage query credentials can fall back to provider config (#360, thanks @Sirhexs)
+
+---
+
+## UX Improvements
+
+- Provider search filter: quickly find providers by name (#435, thanks @TinsFox)
+- Provider icon colors: customize provider icon colors for quicker visual identification (#385, thanks @yovinchen)
+- Keyboard shortcut: `Cmd/Ctrl + ,` opens Settings (#436, thanks @TinsFox)
+- Skip Claude Code first-run confirmation dialog (optional)
+- Closable toasts: close buttons for switch toast and all success toasts (#350, thanks @ForteScarlet)
+- Update badge navigation: clicking the update badge opens the About tab
+- Settings page tab style improvements (#342, thanks @wenyuanw)
+- Smoother transitions: fade transitions for app/view switching and exit animations for panels
+- Proxy takeover active theme: apply an emerald theme while takeover is active
+- Dark mode readability improvements for forms and labels
+- Better window dragging area for full-screen panels (#525, thanks @zerob13)
+
+---
+
+## Platform Notes
+
+### Windows
+
+- Prevent terminal windows from appearing during version checks
+- Improve window sizing defaults (minimum width/height)
+- Fix black screen on startup by using the system titlebar
+- Add a fallback for `crypto.randomUUID()` on older WebViews
+
+### macOS
+
+- Use `.app` bundle path for autostart to avoid terminal window popups (#462, thanks @majiayu000)
+- Improve tray/icon behavior and header alignment
+
+---
+
+## Packaging
+
+- Linux: RPM and Flatpak packaging targets are now available for building release artifacts
+
+---
+
+## Notes
+
+- Security improvements for the JavaScript executor and usage script execution (#151, thanks @luojiyin1987).
+- SQL import is restricted to CC Switch exported backups to reduce the risk of importing unsafe or incompatible SQL dumps.
+- Proxy takeover modifies CLI live configs; CC Switch will back up the live config before redirecting it to the local proxy. If you want to revert, disable takeover/stop the proxy and restore from the backup when needed.

+
+> ローカル API プロキシ、自動フェイルオーバー、Universal Provider、多アプリ対応の強化
+
+**[English →](release-note-v3.9.0-en.md) | [中文版 →](release-note-v3.9.0-zh.md)**
+
+---
+
+## 概要
+
+CC Switch v3.9.0 は v3.9 ベータ（`3.9.0-1`、`3.9.0-2`、`3.9.0-3`）の安定版です。
+ローカル API プロキシ（アプリ別テイクオーバー対応）、自動フェイルオーバー、Universal Provider を追加し、Claude Code / Codex / Gemini CLI の安定性と操作性を大きく改善しました。
+
+**リリース日**：2026-01-07
+
+---
+
+## ハイライト
+
+- ローカル API プロキシ：Claude Code / Codex / Gemini CLI を統一的にプロキシ
+- 自動フェイルオーバー：サーキットブレーカーとアプリ別のフェイルオーバーキュー
+- Universal Provider：1つの設定を複数アプリへ同期（NewAPI などのゲートウェイ向け）
+- Skills の改善：マルチアプリ対応、SSOT + React Query による管理の統一
+- 共通設定スニペット：エディタ内容または現在のプロバイダから抽出
+- MCP インポート：インストール済みアプリから MCP servers を取り込み
+- 使用量の改善：自動更新、キャッシュ指標、タイムゾーン修正
+- Linux パッケージ：RPM / Flatpak の成果物を追加
+
+---
+
+## 主要機能
+
+### ローカル API プロキシ（Local API Proxy）
+
+- ローカルで高性能な HTTP プロキシサーバーを起動（Axum ベース）
+- Claude Code / Codex / Gemini CLI の API リクエストを統一的に扱う
+- アプリ別テイクオーバー：アプリごとにプロキシ経由にするかを個別に切り替え可能
+- Live 設定テイクオーバー：有効化時に CLI の live 設定をバックアップし、ローカルプロキシへリダイレクト
+- 監視：リクエストログと使用量統計でデバッグとコスト把握を支援
+- エラーリクエストのログ：失敗したプロキシリクエストも詳細に記録してデバッグを容易に（#401、@yovinchen に感謝）
+
+### 自動フェイルオーバー（Auto Failover / サーキットブレーカー）
+
+- 障害を検知して保護（サーキットブレーカー）を自動で発動
+- 現在のプロバイダが不調な場合、バックアッププロバイダへ自動切り替え
+- アプリごとに独立したフェイルオーバーキューとヘルス状態を管理
+- フェイルオーバーを無効化している場合、タイムアウト/リトライ関連の設定は通常フローに影響しません
+
+### Skills 管理
+
+- Claude Code と Codex の Skills をマルチアプリで利用可能にし、旧レイアウトからの移行もよりスムーズに（#365、#378、@yovinchen に感謝）
+- SSOT + React Query による Skills 管理の統一で、状態の一貫性と更新挙動を改善
+- Discovery の体験と性能を改善：
+  - スキャン時に隠しディレクトリをスキップ
+  - Discoverable skills に長寿命キャッシュを適用して高速化
+  - ローディング表示の改善と、インポート/更新などの操作導線を整理
+  - Skills リポジトリのブランチ設定を修正（#505、@kjasn に感謝）
+
+### Universal Provider
+
+- 複数アプリで共有できるプロバイダ設定を追加（Claude/Codex/Gemini へ同期）（#348、@Calcium-Ion に感謝）
+- NewAPI のような複数プロトコル対応の API ゲートウェイを想定
+- 1つのプロバイダ内でアプリ別にデフォルトモデルを割り当て可能
+
+### 共通設定スニペット（Claude/Codex/Gemini）
+
+- 「共通設定スニペット」を保持し、有効化したプロバイダへマージ/追記
+- 新しい抽出フロー：
+  - エディタの現在内容から抽出（編集している内容）
+  - エディタ内容がない場合は、現在アクティブなプロバイダから抽出
+- Codex の抽出はより安全：
+  - `model_provider`、`model`、および `model_providers` テーブル全体など、プロバイダ固有の設定を除去
+  - `[mcp_servers.*]` 配下の `base_url` は保持し、MCP 設定を壊しにくくしています
+
+### MCP 管理
+
+- インストール済みアプリから MCP servers をインポート
+- 安定性向上：対象 CLI が未インストールなら同期をスキップし、無効な Codex `config.toml` も適切に扱います（#461、@majiayu000 に感謝）
+- Windows 互換性：MCP エクスポート時の npx/npm 呼び出しを `cmd /c` でラップ
+
+### 使用量と価格データ

+- プロバイダのアイコン色：アイコンに任意の色を設定して見分けやすく（#385、@yovinchen に感謝）
+- ショートカット：`Cmd/Ctrl + ,` で設定を開く（#436、@TinsFox に感謝）
+- Claude Code の初回確認ダイアログをスキップ可能（任意）
+- トースト通知のクローズボタン：切り替え通知と成功通知を閉じられるように（#350、@ForteScarlet に感謝）
+- 更新バッジをクリックすると About タブへ移動
+- 設定ページのタブスタイル改善（#342、@wenyuanw に感謝）
+- アプリ/ビュー切り替えのフェードとパネル終了アニメーション
+- プロキシテイクオーバー中はエメラルド系テーマを適用して状態を分かりやすく
+- ダークモードの視認性改善
+- FullScreenPanel のウィンドウドラッグ領域を改善（#525、@zerob13 に感謝）

+# CC Switch v3.9.0
+
+> 本地 API 代理、自动故障切换、统一供应商与多应用工作流增强
+
+**[English →](release-note-v3.9.0-en.md) | [日本語版 →](release-note-v3.9.0-ja.md)**
+
+---
+
+## 概览
+
+CC Switch v3.9.0 是 v3.9 测试版序列（`3.9.0-1`、`3.9.0-2`、`3.9.0-3`）的稳定版。
+本次更新带来本地 API 代理（支持按应用接管）、自动故障切换、统一供应商（Universal Provider），并对 Claude Code / Codex / Gemini CLI 的稳定性与使用体验做了大量改进。
+
+**发布日期**：2026-01-07
+
+---
+
+## 重点内容
+
+- 本地 API 代理：Claude Code / Codex / Gemini CLI 统一接入
+- 自动故障切换：熔断保护 + 每个应用独立的 failover 队列
+- 统一供应商：一份配置可同步到多个应用（适合 NewAPI 等网关）
+- Skills 相关增强：支持多应用、管理架构统一（SSOT + React Query）
+- 通用配置片段：支持从编辑器内容或当前供应商提取可复用片段
+- MCP 导入：支持从已安装应用导入 MCP servers
+- 用量增强：自动刷新、缓存命中/创建指标、时区修复
+- Linux 打包：新增 RPM 与 Flatpak 制品
+
+---
+
+## 主要功能
+
+### 本地 API 代理（Local API Proxy）
+
+- 运行一个本地高性能 HTTP 代理服务（基于 Axum）
+- 统一代理 Claude Code、Codex、Gemini CLI 的 API 请求
+- 按应用接管：你可以分别控制每个应用是否走本地代理
+- Live 配置接管：启用接管时，会备份并重定向 CLI 的 live 配置到本地代理
+- 监控能力：记录请求日志与用量统计，便于排错与成本分析
+- 错误请求日志：代理会记录失败请求的详细信息，便于定位问题（#401，感谢 @yovinchen）
+
+### 自动故障切换（Auto Failover / 熔断）
+
+- 自动检测供应商异常并触发熔断保护
+- 当前供应商不可用时自动切换到备用供应商
+- 每个应用维护独立的 failover 队列，并实时追踪健康状态
+- 当关闭故障切换时，超时/重试相关配置不会影响正常请求流程
+
+### Skills 管理
+
+- Skills 支持 Claude Code 与 Codex 多应用使用，并提供旧结构到新结构的平滑迁移（#365、#378，感谢 @yovinchen）
+- Skills 管理架构统一（SSOT + React Query），状态刷新与数据一致性更稳定
+- 发现（Discovery）体验与性能改进：
+  - 扫描时跳过隐藏目录
+  - Discoverable skills 使用长生命周期缓存提升性能
+  - 增加加载状态提示，导入/刷新等操作入口更显眼
+  - 修复 Skills 仓库分支配置错误（#505，感谢 @kjasn）
+
+### 统一供应商（Universal Provider）
+
+- 新增“跨应用共享”的供应商配置，可同步到 Claude/Codex/Gemini（#348，感谢 @Calcium-Ion）
+- 适配支持多协议的 API 网关（例如 NewAPI）
+- 同一个供应商下可按应用分别设置默认模型映射
+
+### 通用配置片段（Claude/Codex/Gemini）
+
+- 维护一段“通用配置片段”，并将其合并/追加到启用该功能的供应商配置中
+- 新增“提取通用配置片段”工作流：
+  - 优先从编辑器当前内容提取（你正在编辑的内容）
+  - 若未提供编辑器内容，则从当前激活的供应商提取
+- Codex 场景提取更安全：
+  - 自动移除 `model_provider`、`model` 以及整个 `model_providers` 表等供应商相关内容
+  - 会保留 `[mcp_servers.*]` 下的 `base_url`，避免误伤 MCP 配置
+
+### MCP 管理
+
+- 支持从已安装应用导入 MCP servers
+- 同步更稳健：目标 CLI 未安装则跳过；无效的 Codex `config.toml` 可更优雅处理（#461，感谢 @majiayu000）
+- Windows 兼容性：MCP 导出相关的 npx/npm 调用使用 `cmd /c` 包裹
+
+### 用量与计费数据
+
+- 用量与计费增强：自动刷新、缓存命中/创建指标、时区修复，以及内置价格表更新（#508，感谢 @yovinchen）
+- 深链支持：可通过 deeplink 导入用量查询配置（#400，感谢 @qyinter）
+- 用量统计支持提取模型信息（#455，感谢 @yovinchen）
+- 用量查询凭证支持从供应商配置回退（#360，感谢 @Sirhexs）
+
+---
+
+## 体验优化
+
+- 供应商搜索过滤：按名称快速查找（#435，感谢 @TinsFox）
+- 供应商图标颜色：支持为供应商图标设置自定义颜色，便于快速区分（#385，感谢 @yovinchen）
+- 快捷键：`Cmd/Ctrl + ,` 打开设置（#436，感谢 @TinsFox）
+- 可跳过 Claude Code 首次确认弹窗（可选）
+- Toast 通知可关闭：切换提示与成功提示都支持关闭按钮（#350，感谢 @ForteScarlet）
+- 点击更新徽章会自动跳转到 About 标签页
+- 设置页 Tab 样式改进（#342，感谢 @wenyuanw）
+- 更顺滑的切换动效：应用/视图淡入淡出与面板退出动画
+- 代理接管激活时应用翡翠绿主题，便于一眼识别当前状态
+- 深色模式可读性增强（表单与标签对比度等）
+- FullScreenPanel 的窗口拖拽区域优化（#525，感谢 @zerob13）
+
+---
+
+## 平台说明
+
+### Windows
+
+- 版本检查不再弹出终端窗口
+- 改进窗口尺寸默认值（最小宽高）
+- 修复部分设备启动黑屏问题（使用系统标题栏方案）
+- 兼容旧 WebView：为 `crypto.randomUUID()` 增加降级方案
+
+### macOS
+
+- 自启动使用 `.app bundle` 路径，避免弹出终端窗口（#462，感谢 @majiayu000）
+- 托盘与标题栏相关体验优化
+
+---
+
+## 打包
+
+- Linux：新增 RPM 与 Flatpak 打包目标，用于生成发布制品
+
+---
+
+## 说明与注意事项
+
+- 安全增强：修复 JavaScript 执行器与用量脚本相关的安全问题（#151，感谢 @luojiyin1987）。
+- 为降低导入风险，SQL 导入被限制为仅允许导入 CC Switch 自己导出的备份。
+- Proxy 接管会修改 CLI 的 live 配置；CC Switch 会在重定向前自动备份 live 配置。如需回退，可关闭接管/停止代理，并在必要时从备份恢复。

+# 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.

+//! 请求体过滤模块
+//!
+//! 过滤不应透传到上游的私有参数，防止内部信息泄露。
+//!
+//! ## 过滤规则
+//! - 以 `_` 开头的字段被视为私有参数，会被递归过滤
+//! - 支持白名单机制，允许透传特定的 `_` 前缀字段
+//! - 支持嵌套对象和数组的深度过滤
+//!
+//! ## 使用场景
+//! - `_internal_id`: 内部追踪 ID
+//! - `_debug_mode`: 调试标记
+//! - `_session_token`: 会话令牌
+//! - `_client_version`: 客户端版本
