+### 协议插件化（`plugins/decoders`）
+- 目标：每个协议作为独立 DLL 插件，可按需安装与动态加载。
+- 关键接口：
+  - `IProtocolPlugin`：暴露 `protocolName()` / `apiVersion()` / `createBundle()`。
+  - `ProtocolBundle`：`codec/decoder/format` 三件套。
+- 加载流程：
+  - `SerialBackend` 启动时调用 `SerialManager::loadPlugins()`。
+  - `SerialManager` 扫描 `appDir/plugins/decoders` 目录，按平台过滤后缀（Windows: `.dll`）。
+  - 校验 `apiVersion`，创建并注册协议 bundle。
+  - 通过 `m_pluginLoaders` 保持插件常驻，避免对象失效。

 ## 更新记录
 
+- 2026-01-20：协议解码插件化（DLL），SerialBackend 启动时动态加载 `plugins/decoders`，安装器支持按组件选择协议插件。
 - 2026-01-11：新增 `QtSerialTransport`（`QSerialPort` 传输实现）并设为默认传输；补齐点选拾取逻辑；新增数据流/时序图并补充可视化 TODO 说明。
 - 2026-01-12：`LeftPanel` 新增颜色映射参数；`AppBackend`/`GLWidget` 增加颜色与范围接口，shader 使用三色渐变映射数据值。
 - 2026-01-11：补充串口配置流程图与配置接口说明（协议/参数/解码器绑定/打开流程）。
