+### HTTPS 反向代理
+
+正式安装默认监听 `8091`（可通过 `ERP_SERVER_PORT` 覆盖）。Nginx、宝塔、Caddy 或 CDN 终止 HTTPS 后，必须把公网协议和主机转发给 Spring Boot；否则浏览器的同源 API 请求会被误判为跨域，并收到纯文本 `403 Invalid CORS request`，前端表现为“响应非 JSON (HTTP 403)”。Nginx 的代理位置至少包含：
+

+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+}
+```
+
+如果 Nginx 前面还有 Cloudflare 等上游代理，`X-Forwarded-Proto` 必须保留浏览器实际使用的 `https`，不能被内层 HTTP 链路覆盖。前端与 `/api/oa/*` 推荐使用同一个公网域名；不要在 Nginx 中附加 `Access-Control-Allow-Origin *`。

 1. 下载正式归档、`SHA256SUMS` 和签名并验证 Ed25519/SHA-256；独立安装器资产只在首次安装使用。
 2. 拒绝路径穿越、符号链接和结构不完整的安装包。

 更新过程使用操作系统文件锁，同一安装目录同时只允许一个更新任务。手动触发可执行：
 
 ```bash
-/opt/kaidi-erp/current/bin/erp-update install 0.2.0

 在线更新依赖安装器注册的 systemd 或 launchd 服务来拉起新旧版本。使用 `--no-service` 时后台更新默认关闭；如由其他进程管理器接管，须先确认它会在 ERP 进程退出后自动重启，再手工启用 `OA_UPDATE_ENABLED=true`。健康检查默认最多等待 120 秒、每 2 秒轮询一次，可分别通过 `ERP_UPDATE_HEALTH_TIMEOUT_SECONDS` 和 `ERP_UPDATE_HEALTH_POLL_SECONDS` 调整。
