- 服务端可以托管前端构建产物（AGENTLAB_WEB_DIST）：页面路由回退到 index.html，/api 下不存在的路径照旧是 JSON 404， 挡住路径穿越；index.html 不缓存，assets/ 带哈希的文件长缓存；没设时行为完全不变 - scripts/prod.sh：不用 Docker 的生产运行。按需构建前端，单进程、不热重载，默认只听本机，--host 开放到局域网并提示没有登录 - Dockerfile（多阶段构建，Linux 镜像）：前端在构建机架构上构建，运行阶段用 python:3.12-slim，依赖装进独立的 venv， 以非 root 用户（uid 10001）运行，数据在 /data，带健康检查；.dockerignore 排除 .env、data/、各种库文件，镜像里实测没有密钥和数据库 - scripts/package-docker.sh：构建指定平台的镜像（默认按本机架构，可选 linux/amd64），打成 release/agentlab-<版本>-linux-<架构>.tar，里面有 image.tar、deploy.sh、agentlab.env、README.md、SHA256SUMS - deploy/deploy.sh：目标机上只依赖 Docker，离线可用。install / start / stop / restart / status / logs / upgrade / uninstall； 检查架构和配置，自动导入镜像，替换容器时保留旧容器以便回退，数据永远保留，日志轮转 - 修正 bubblewrap 的可用性判断：以前只看有没有装 bwrap，容器里和 Ubuntu 24.04 默认配置下装了却建不了命名空间， 每次执行代码都失败；现在真起一次试，不能用就退回下一个后端，并写明原因 - README 增加「生产部署」一节，部署细节见 deploy/README.md
