+发布资产名称必须包含当前平台，例如 `tallynote-1.1.2-linux-x64-glibc.tar.gz`。构建脚本会同时生成完整安装包和轻量更新包：`tallynote-1.1.2-linux-x64-glibc.tar.gz` 用于首次安装，`tallynote-1.1.2-linux-x64-glibc.update-<锁文件 SHA256>.tar.gz` 仅用于复用现有运行时的后台更新。同一个 Release 只保留一个 `SHA256SUMS`；有签名时再保留一个 `SHA256SUMS.sig`，签名覆盖清单完整原文。

 将环境文件中的 `TALLYNOTE_UPDATE_STRATEGY=systemd`、`TALLYNOTE_UPDATE_METADATA_URL` 和 `TALLYNOTE_UPDATE_ALLOWED_HOSTS` 配好后，后台“系统更新”会读取 Gitea 的 `/api/v1/repos/<owner>/<repo>/releases/latest`。检查结果只显示当前平台匹配且通过 SHA-256 校验的资产；如果配置了 `TALLYNOTE_UPDATE_PUBLIC_KEY_FILE` 并启用签名要求，再额外验证 Ed25519 签名。
 
-后台更新分为两个明确阶段。管理员先在“系统更新”读取最新 Release 的版本号、发布时间和更新说明，点击“下载更新包”；root 更新器会在主服务继续运行时下载、校验 SHA-256、解包并暂存。页面显示“下载完成，等待应用”后，管理员再点击“立即更新”。应用阶段才会短暂停止服务、备份数据、切换 release、启动并执行健康检查；页面显示重启倒计时并自动重试连接。浏览器只提交版本号、任务 ID 和确认标志，不能提交 URL 或文件路径。

 Web 进程把受保护的任务文件交给 root 的 `tallynote-update.path`/`tallynote-update.service`，root runner 会重新读取配置源并验证 metadata、清单和暂存目录，不信任队列文件中的 URL 或摘要。切换失败或健康检查失败会恢复旧版本；手动回滚：
