+- 后端提供进程内动态库插件系统，但非常不成熟
+- 有特殊需求建议直接改源码，而不是开发插件
+- 这个插件系统**没有做任何安全限制**，这是为了给插件最大的功能性与自由度
+- 也正因如此，**任何第三方插件的安全性都无法保证**
+- 强烈建议：只使用开源插件，并且自行审查代码后再编译使用
+- 不要使用他人发的二进制插件(`dll` / `so` / `dylib`)
+- 插件开发文档与示例请看：[src-plugin/examples](src-plugin/examples)

+对于个人开发的项目来说，这个问题几乎是无解的(~~需要购买数字证书给软件签名，甚至给杀毒软件交保护费~~)  
+我能想到的解决办法只有：

+1. 根据下面的**如何构建(build)**，自行编译
+2. 希望你相信我的承诺，我承诺你在[Release页面](https://github.com/lanyeeee/bilibili-video-downloader/releases)下载到的所有东西都是安全的

+## 🛠️如何构建(build)

+构建非常简单，一共就3条命令  
+~~前提是你已经安装了Rust、Node、pnpm~~
+
+#### 📋前提
+
+- [Rust](https://www.rust-lang.org/tools/install)
+- [Node](https://nodejs.org/en)
+- [pnpm](https://pnpm.io/installation)
+
+#### 📝步骤
+
+#### 1. 克隆本仓库
+
+```
+git clone https://github.com/lanyeeee/bilibili-video-downloader.git
+```
+
+#### 2.安装依赖
+
+```
+cd bilibili-video-downloader
+pnpm install
+```
+
+#### 3.构建(build)
+
+```
+pnpm tauri build
+```
+
+## 🤝提交PR
+
+**PR请基于`develop`分支开发，并提交至`develop`分支**
+
+**提交前请先：**
+
+1. 运行`pnpm format`以保证代码格式正确
+2. 运行`pnpm check`并确认无报错
+
+**如果想新加一个功能，请先开个`issue`或`discussion`讨论一下，避免无效工作**
+
+其他情况的PR欢迎直接提交，比如：
+
+1. 🔧 对原有功能的改进
+2. 🐛 修复BUG

+# 插件系统（v1，实验性）
+
+> [!WARNING]
+> 插件是进程内动态库(`dll` / `so` / `dylib`)，与宿主进程同权限运行  
+> 没有沙箱、权限隔离、签名校验，也没有网络或文件系统限制  
+> 插件还可以读取完整的宿主配置(包括 `sessdata`)
+
+## 当前示例
+
+- 当前仓库的示例插件只有一个：`basic-example`
+- 位置：`src-plugin/examples/basic-example`
+- 用途：演示 Descriptor、Hook 处理、异步逻辑、读取宿主配置、返回修改后的 `payload`
+
+## 快速构建示例
+
+```bash
+cd src-plugin/examples
+cargo build --release
+```
+
+构建产物位于 `src-plugin/examples/target/release/`，文件名按平台分别是：
+
+- Windows: `basic_example.dll`
+- Linux: `libbasic_example.so`
+- macOS: `libbasic_example.dylib`
+
+## 如何加载插件
+
+- 在应用设置页的插件面板点击“添加插件”，选择动态库文件
+- 后端要求路径必须是绝对路径，且文件必须存在
+- 成功后会写入 `app_data_dir/plugin.json` 持久化配置
+- `plugin.json` 保存字段：`path`、`enabled`、`priority`、`descriptor`
+
+## Descriptor（插件内声明）
+
+`PluginDescriptorV1` 由插件代码返回，宿主不会直接修改：
+
+- `sdk_api_version`：SDK API 版本，当前必须等于 `1`
+- `id`：插件 ID
+- `name`：展示名称
+- `version`：插件版本
+- `hooks`：声明插件希望被调用的 Hook 点列表
+- `failure_policy`：失败策略，`FailOpen` 或 `FailClosed`
+- `description`：插件描述
+
+## 运行顺序与优先级
+
+- Hook 点相同的插件，宿主按 `priority` 从大到小执行
+- 每个 Hook 点按顺序串行执行，不是并行
+- 前一个插件返回后的修改，会成为后一个插件看到的输入
+
+## Hook 时机（以实际代码为准）
+
+| HookPoint            | 触发位置                        |
+|:---------------------|:----------------------------|
+| `AfterPrepare`       | `prepare()` 成功之后，开始下载前      |
+| `BeforeVideoProcess` | 视频任务和音频任务结束后，视频处理任务前        |
+| `OnCompleted`        | 所有任务结束后，`completed_ts` 已写入后 |
+
+三个 Hook 都可读写 `progress`，但修改只有在当前 Hook 返回后才会被宿主应用。
+
+## 输入输出协议
+
+- 输入：`HookInputV1 { hook_point, payload, readonly_meta }`
+- 输出：`HookOutputV1 { payload }`
+- `payload` 是枚举 `HookPayloadV1`，必须与 `hook_point` 匹配
+- 不匹配会被判定为插件输出无效，再按失败策略处理
+- `readonly_meta` 包含 `app_version`、`os`、`arch`、`process_id`
+
+## 可修改范围与约束
+
+- `payload.progress` 大多数字段都可被插件修改
+- `task_id` 明确禁止修改，改动会被宿主拒绝
+- 宿主没有提供修改Config的 Host API
+
+## 失败策略
+
+- `FailOpen`：插件出错时记录日志，继续执行后续流程
+- `FailClosed`：插件出错时中断当前下载流程并返回错误
+- 插件返回 `Err(...)` 时，宿主会调用 `bilibili_video_downloader_plugin_last_error_v1` 读取错误文本
+
+## Host API（当前仅 v1）
+
+插件可在 `on_hook` 中调用：
+
+- `host::get_config()`：读取宿主配置快照（`HostConfigV1`）
+
+注意：
+
+- 该配置是只读快照
+- 返回内容包含敏感信息（例如 `sessdata`）
+
+## SDK 入口（插件侧）
+
+- 实现 trait：`PluginV1`
+- 使用宏导出：`export_plugin_v1!(YourPluginType)`
+- 插件类型需要满足：`Default + Send + 'static`
+
+常规最小结构：
+
+```rust
+use bilibili_video_downloader_plugin_sdk::{
+    HookInputV1, HookOutputV1, PluginDescriptorV1, PluginV1, export_plugin_v1, eyre
+};
+
+#[derive(Default)]
+struct MyPlugin;
+
+impl PluginV1 for MyPlugin {
+    fn descriptor(&self) -> PluginDescriptorV1 {
+        unimplemented!()
+    }
+
+    fn on_hook(&mut self, input: HookInputV1) -> eyre::Result<HookOutputV1> {
+        let _ = input;
+        unimplemented!()
+    }
+}
+
+export_plugin_v1!(MyPlugin);
