+- **生产机不执行 `git clone`、`git pull` 或远程脚本拼接。** 源码仓库是
+  `https://git.awaioi.com/ERP-Team/kaidi.git`，生产安装和后台更新使用同一仓库生成的公开 Gitea Release。
+- 安装器先读取 Gitea Release API，再下载 `release-manifest.json`、签名、公钥和压缩包，校验固定公钥指纹、RSA 签名、版本、文件名和 SHA-256；校验失败不会安装。
+- 后台“获取版本”只查询 Release；“下载”才下载并校验；“立即更新并重启”才备份数据库、切换 `current` 并重启服务。更新器下载的是 Release 制品，不是 Git 工作树。
+- MySQL 是**已有数据库**，应用只通过向导写入的 `DB_URL`、`DB_USERNAME`、`DB_PASSWORD` 连接它；安装器不安装 MySQL、不创建数据库、不修改数据库服务。填写 `127.0.0.1` 表示 MySQL 与 Java 应用在同一台服务器，端口以实际监听端口为准，不默认假设 `3307`。
+- `KAIDI_APP_PORT` 只决定 Java 回环监听端口，默认 `18080`；反向代理必须指向安装器输出的 `PROXY_TARGET`。安装器不会替你修改 Nginx 或宝塔站点配置。
+- 发布归档使用无顶层目录的 `tar.gz`，只包含 `app.jar`、`public/`、`ops/`、`VERSION`；打包阶段禁用 macOS 扩展属性并拒绝开发数据库回退值。
