+<summary><b>Q: macOS 上提示 Keychain/凭据管理不可用，OAuth 无法保存？</b></summary>
+
+这是 macOS 安全机制导致的常见问题，通常出现在未签名的应用或从 Downloads 直接运行的场景。
+这是**临时方案**，仅适合个人设备：
+
+1. 将应用移动到 `/Applications`
+2. 打开终端执行以下命令（每次更新后都需要重新执行）
+
+```plaintext
+sudo xattr -dr com.apple.quarantine "/Applications/Antigravity Manager 2.app"
+codesign --force --deep --sign - "/Applications/Antigravity Manager 2.app"
+```
+
+重新打开应用后，Keychain 应会提示授权（可选“始终允许”）。

 ## 1. 核心功能
 
 ### 1.1 账号池管理
+
 - **添加账号**：支持通过 Google OAuth 授权码添加账号。
 - **列表展示**：展示所有已添加的账号，包括头像、邮箱、最后使用时间。
 - **状态监控**：实时显示账号状态（Active, Rate Limited, Expired）以及是否为当前活动账号。
 - **删除账号**：支持从本地数据库中移除账号。
 
 ### 1.2 配额实时监控
+
 - **多模型支持**：分别监控 `gemini-pro`, `claude-3-5-sonnet` 等模型的配额使用情况。
 - **可视化展示**：通过进度条和颜色（绿/黄/红）直观展示剩余配额百分比。
 - **自动/手动刷新**：支持手动刷新配额，系统也会在切换前自动检查。
 
 ### 1.4 智能自动切换 (Intelligent Auto-Switching)
+
 - **无限池模式**：当检测到当前账号配额不足（<5%）或被限流时，系统会自动寻找最佳备用账号并切换。
 - **后台监控**：内置 `CloudMonitorService`, 默认每 5 分钟轮询一次所有账号的 Quota 状态。
 - **全局开关**：用户可在界面上一键开启或关闭此功能。

 IDE 将鉴权信息存储在 `state.vscdb` 的 `ItemTable` 表中，key 为 `jetskiStateSync.agentManagerInitState`。

 3.  **重构**：根据新的 Access Token 和 Refresh Token 构建新的 Field 6 并插入。

 1.  **Token 检查**：检查目标账号 Token 是否临期，如需刷新则自动刷新。

 ### 2.5 自动切换逻辑 (`AutoSwitchService`)
+
 1.  **监控**：`CloudMonitorService` 定时（5分钟）轮询所有账号配额。
 2.  **判断**：如果当前活动账号的所有关键模型配额低于 5%，或状态为 `rate_limited`。
 3.  **择优**：从账号池中筛选状态为 `active` 且配额充足的账号，按配额剩余量排序。
 4.  **执行**：自动调用 `switchCloudAccount` 完成切换，并通知用户。
 
 ### 2.6 安全加固 (Security Hardening)
+
 - **密钥管理**：使用操作系统原生凭据管理器（Windows Credential Manager / macOS Keychain）通过 `keytar` 库安全存储 Master Key（AES-256）。
 - **数据加密**：所有敏感数据（`token_json`, `quota_json`）在存入 SQLite 数据库前均使用 `AES-256-GCM` 算法加密。
 - **自动迁移**：应用启动时会自动检测并迁移旧的明文数据，确保安全性平滑升级。
