+## Threat Model / 威胁模型
+
+CC Switch is a local desktop application. It manages configuration files for AI coding CLIs on the user's own machine. There is no project-operated cloud backend, no multi-user model, and no privilege separation from the user who runs it.
+
+CC Switch 是一个本地桌面应用，用于管理本机上各 AI 编程 CLI 的配置文件。本项目不运营任何云端后端，没有多用户模型，也不与运行它的用户之间存在权限隔离。
+
+It does, however, run a **local HTTP proxy** whose listen address and port are user-configurable and **may be bound to a non-loopback interface**. Requests arriving at that listener are untrusted input and are in scope — see Scope below.
+
+但它会启动一个**本地 HTTP 代理**，其监听地址与端口可由用户配置，**可能绑定到非 loopback 接口**。抵达该监听端口的请求属于不可信输入，在范围内——见下方「范围」。
+
+### The bundled renderer is inside the trust boundary / 打包的渲染进程属于信任边界之内
+
+The bundled WebView renderer is treated as a trusted component. This is a **scoping decision, supported by the facts below rather than derived from them** — the facts are what make the decision checkable, and if any ceases to hold the decision must be revisited. Verified against v3.18.0:
+
+打包的 WebView 渲染进程被视为可信组件。这是一项**范围划定决策，由下列事实支撑，而非从中必然推出**——这些事实的作用是让该决策可被核验；一旦任一条不再成立，该决策必须重新评估。已针对 v3.18.0 核实：
+
+1. **No remote executable content is loaded.** `frontendDist` is bundled at build time (`src-tauri/tauri.conf.json`); the codebase contains no `<iframe>`, no `<webview>`, and no remote script or stylesheet URL. The application *does* retrieve remote **data** — model pricing JSON and provider avatars — which CSP permits via `connect-src`/`img-src`; such data is treated as untrusted input, not as content.
+   前端资源在构建期打包，代码库中不存在 `<iframe>`、`<webview>` 或远程脚本/样式地址。应用**确实**会获取远程**数据**（模型定价 JSON、供应商头像），CSP 经 `connect-src`/`img-src` 允许之；此类数据按不可信输入对待，不作为内容。
+2. **CSP restricts script execution to bundled assets** — `script-src 'self'` (`src-tauri/tauri.conf.json`).
+   CSP 将脚本执行限制在打包资源内。
+3. **No dynamic code evaluation.** There is no `eval()` or `new Function()` anywhere under `src/`.
+   `src/` 下不存在 `eval()` 或 `new Function()`。
+4. **The single HTML sink never receives user-controlled content.** `src/components/ProviderIcon.tsx` uses `dangerouslySetInnerHTML` exactly once; the user-supplied `icon` field is used **solely as a lookup key** into a build-time icon table, never as content.
+   全库唯一的 `dangerouslySetInnerHTML` 位于 `src/components/ProviderIcon.tsx`；用户提供的 `icon` 字段**仅作为查表的键**用于构建期图标表，永不作为内容。
+
+**What this excludes — and what it does not.** Out of scope: reports whose only path to the IPC surface is **direct invocation from DevTools or from a locally modified frontend**. Someone in that position controls the machine already.
+
+**它排除什么、不排除什么。** 不在范围内的是：抵达 IPC 接口的**唯一途径**为**从 DevTools 或本地改造过的前端直接调用**的报告。处于该位置的人已经控制了这台机器。
+
+**Still in scope:** any complete, demonstrable chain in which an *untrusted* source — a `ccswitch://` deep link, a remote sync payload, remote data, an inbound proxy request, or an XSS — reaches a high-privilege IPC command. The trust placed in the renderer covers the code we ship, not arbitrary values that flow through it.
+
+**仍在范围内**：任何完整、可演示的利用链，其中**不可信来源**——`ccswitch://` deeplink、远程同步载荷、远程数据、代理入站请求或 XSS——抵达高权限 IPC 命令。对渲染进程的信任覆盖的是我们发布的代码，而非流经其中的任意值。
+
+### Invalidation triggers / 声明失效条件
+
+The scoping decision above is void the moment any of the following becomes true. Reports demonstrating any of these are **always in scope**, and we ask to be told about them:
+
+一旦下列任一条件成立，上述范围划定立即作废。证明下列任一情形的报告**始终在范围内**，也欢迎报告：
+
+- Remote **executable or navigable** content is loaded into the WebView — iframe, webview, remote script, remote stylesheet, or navigation to a remote origin
+  远程**可执行或可导航**内容被载入 WebView——iframe、webview、远程脚本、远程样式表，或导航至远程源
+- `script-src` is relaxed beyond `'self'`
+  `script-src` 被放宽到 `'self'` 之外
+- `eval()` or `new Function()` is introduced

+- Imported files: SQL import/export, provider and MCP config import / 导入文件：SQL 导入导出、供应商与 MCP 配置导入
+- Upstream API responses processed by the local proxy (`src-tauri/src/proxy/`) / 本地代理处理的上游 API 响应
+- Remote data rendered or acted upon by the renderer (model pricing, avatars) / 渲染进程展示或据以行动的远程数据（模型定价、头像）

+  → 不属豁免：路径或内容由 deeplink、同步载荷、代理请求等不可信来源控制的情形。攻击者与用户拥有相同的文件系统权限，并不等于该操作出自用户的决定——那是 confused deputy 攻击，**在范围内**。
+- **User-authored integrations executing by design.** MCP servers, terminal launch and usage scripts run commands because that is their purpose. Where the user typed the command themselves and enabled it themselves, execution is the feature, not the bug.
+  **用户亲手编写的集成按设计执行命令。** MCP server、终端启动、用量脚本执行命令是其本职。命令由用户自己输入、并由用户自己启用时，执行本身是功能而非缺陷。

There the required security property is *informed consent*, and the following are **in scope**: the command, arguments, environment or script body being hidden, truncated or misrepresented in the confirmation UI; and any integration carrying executable content being enabled without an explicit user decision.
+  → 不属豁免：同样的集成**经导入或 deeplink 抵达**时。此时所要求的安全属性是**知情同意**，下列情形**在范围内**：确认界面隐藏、截断或错误展示命令、参数、环境变量或脚本正文；以及任何携带可执行内容的集成在缺少用户明确决定的情况下被启用。

+///
+/// 1. 全库仅一处 `dangerouslySetInnerHTML`（`ProviderIcon.tsx`），其入参是图标
+///    **名字**，经 `hasIcon()` 把关后从手工维护的构建期注册表取 SVG——用户与
+///    深链接都只能给名字，给不了标记内容
+/// 2. 前端无 `eval` / `new Function`
+/// 3. `tauri.conf.json` 的 `frontendDist` 指向打包产物，webview 不加载任何远程
+///    源；界面里也没有 `<iframe>` / `<webview>`
+/// 4. CSP 为 `script-src 'self'`——既不允许内联脚本，也不允许外部脚本
+///
+/// 因此"攻击者能调用本 IPC"这一前提，成立时已意味着他能以当前用户身份执行代码；
+/// 那种情况下绕道本命令并不会让他多拿到任何东西。
+///
+/// # 什么会推翻这个结论
+///
+/// 上面四条任意一条不再成立，本命令就必须改成**只接收 session / provider 标识、

+///
+/// - 渲染任何来自网络或配置文件的富文本 / HTML / SVG 内容
+/// - 引入 `<iframe>`、`<webview>`，或让 webview 导航到远程 origin
+/// - 放宽 CSP 的 `script-src`（例如为了加载第三方脚本或统计 SDK）
