 1. `103` 是正式生产主机，`105` 是云侧入口/历史链路；**本机一律不允许直接 `rsync` 到 `103` 或 `105`**，也不允许在线改源码后继续运行。
 2. **禁止 SSH 登录 `105` 直接修改业务代码**（含服务号菜单脚本 `scripts/wechat-mp-menu.mjs`）。105 上文件是部署产物；变更必须：本地 `test-memind` 修改 → Git commit → 正式发布 → 必要时在目标环境执行 API 同步。详见 [docs/105-server-operations.md](docs/105-server-operations.md)。
 2. **Portal 生产必须是无源码 runtime 模式**：构建只发生在本机 Mac，产物是 `.runtime/portal/`；`103` 只接收 runtime artifact、继承持久目录、启动服务，**禁止**在 `103` 上 `npm install`、`npm run build` 或保留可运行源码树。
+2. `MindSpace` 独立服务同样必须走单独 runtime artifact：本地 `node scripts/build-mindspace-service-runtime.mjs` -> `bash scripts/release-mindspace-service-prod.sh` -> 上传 `103` -> 备份 `/Users/john/MindSpace` 与共享 `Memind/.env` -> 原子切换到 `/Users/john/MindSpace` -> 健康检查 `127.0.0.1:8082/health` 与 `/mindspace/v1/contract`；禁止手工 SSH 改线上 `/Users/john/MindSpace` 源码。
 3. Portal 生产发布唯一合法路径是：本地已提交代码 -> 本机 `node scripts/build-portal-runtime.mjs` -> `bash scripts/release-portal-runtime-prod.sh` -> 上传 `103` -> 全量备份 + 持久目录备份 -> 原子切换 live 目录 -> 重启 Portal -> 健康检查。
 4. `scripts/release-prod.sh`（源码包发布）已停用，不得再用于 Portal；`rsync_to_server.sh` 与任何面向 `105` 的直接同步脚本也只保留为禁用提示。
 5. 发布包不得携带运行态资产；`.env`、`MindSpace/`、`data/`、`users/`、`.tailscale/`、`public/plaza-covers/`、`logs/` 只能从线上现有 live 目录继承。

+# MindSpace Service
+
+Standalone MindSpace service source tracked inside the Memind repo.
+
+This service is deployed to production as a separate runtime artifact under
+`/Users/john/MindSpace` and exposes the shared adapter RPC contract that Memind
+can call through `MINDSPACE_SERVER_ADAPTER=remote`.
+
+Production defaults:
+
+- MindSpace service listens on `127.0.0.1:8082`
+- Memind remains on `127.0.0.1:8081`
+- Runtime code lives at `/Users/john/MindSpace`
+- Runtime data continues to use the existing persisted Memind directories:
+  `MindSpace/`, `data/mindspace/`, and `users/`
+
+Key scripts in this repo:
+
+- `node scripts/build-mindspace-service-runtime.mjs`
+- `bash scripts/release-mindspace-service-prod.sh --yes`
