 插件向宿主发起 RPC 后，宿主回写响应失败必须终止这条插件 RPC 读取循环并把写失败正文传给等待方；继续读而不收口会让插件调用看起来像无响应。
 
+插件项目路径清理和本地权限审计属于旁路，但失败仍要写 WebView 诊断；旁路不阻断业务不等于可以静默丢失 IPC/I/O 事实。

 ## 2026-10-03 AGC 随包 plugins 的 feature 档位必须与消费方一致，且门禁会因 build.rs 未重跑而假通过
 
 - **现象**：Windows 本机 `npm run check:generated-bindings`（`npm run lint` 链内，`scripts/check-repository-ci.sh` 的 Repository checks 也走它）在 `build.rs:167:29` panic：`插件随包资源校验失败：随包插件存在未声明文件：.../src-tauri/resources/plugins/agc-godot-editor/native/gdextension/bin/win-x64/agc_godot_editor.dll（目标 x86_64-pc-windows-msvc 与当前 feature 组合不允许；请先执行随包资源准备步骤）`；树上换成 `agc-unity-editor/dotnet/publish/win-x64/Agc.Unity.Attach.exe` 时报同一类错。反向还有更隐蔽的形态：门禁 2 秒就 exit 0 说「通过」，但 tree 上其实带着编辑器产物。
