@@ -269,3 +269,12 @@ Core 的独立数据目录目前不等于已授权 Vault。Python 旧笔记写
 - 安装预览由 Host 注入应用版本、OS 与架构，renderer 只提交根包、当前 Vault 和配置；后台阻塞任务中保持 Vault 绑定稳定并调用完整预览。尚未开放实际安装执行命令。
 - 桌面二进制 5 项测试和全目标 Clippy -D warnings 通过，日志 `.build/extension-commands-tests.log`。新增确认凭据生命周期与并发冲突测试；ACL 文件及生成权限项已更新。
 - 前端确认对话框、桌面包下载/暂存入口、安装执行编排、沙箱及真实 UI 验收尚待完成；extensions capability 仍关闭。本轮不宣称生产化或 D-04 完成。
+
+
+## 增量：社区来源确认界面接入 Host
+
+- 桌面社区检查来源后请求 Host 复核，对话框展示 source_id、候选公钥、原有设置和确认摘要；只有点击确认才调用 Host 确认命令，成功后更新本地目录设置。启用/停用也经同一确认流程更新 Host，旧本地来源不自动迁入信任库。
+- 新增 extensionTrustService，规范 HTTPS 来源、公钥解码和数量限制；确认只传 Host 签发的 review_id 与摘要。两分钟过期或并发冲突提示重新检查；多键确认是逐键调用，部分失败可能已有部分键完成确认，界面不声称整组成功，需重新检查后处理。
+- 来源发现保留服务端 source_id，Web 开发保留本地来源流程。对话框中的错误可见，忙碌时禁止重复确认。
+- 前端全量 99 文件 / 521 项通过，两套 TypeScript 项目检查通过；日志 `.build/extension-trust-ui-tests.log`。新增服务参数/非法输入测试与 Vue 组件确认前无写入、Host 拒绝后不保存测试。测试使用 Host mock，不等同于真实桌面 UI 端到端验收。
+- 桌面包下载暂存、安装确认 UI 与执行编排、沙箱、真实双端及部署验收仍未完成；整体生产化目标继续进行。
