+UniDesk delivery is not complete until the public frontend, public provider ingress, internal core API, PostgreSQL database, local provider-gateway self-connection, and frontend Playwright flow pass one end-to-end check. The canonical automated command is `bun scripts/cli.ts e2e run`.
 
 ## Required Preconditions
 
 - `config.json` `network.publicHost` must be the externally reachable host name or IP of the main server, not `127.0.0.1`, when validating browser access from outside the server.
 - `bunx playwright install chromium` and `bunx playwright install-deps chromium` must have been run on hosts that execute browser E2E tests.
-- The Docker stack must be running through `bun scripts/cli.ts server start`, and `bun scripts/cli.ts server status` must report healthy core, frontend, database, and provider-gateway containers.
+- The Docker stack must be running through `bun scripts/cli.ts server start`, and `bun scripts/cli.ts server status` must report healthy frontend, provider ingress, internal core, database, and provider-gateway containers.

+`bun scripts/cli.ts e2e run` validates the following URLs and internal checks derived from `config.json`:
 
-- Core API: `GET /api/overview` reports `dbReady: true` and at least one online node.
-- Provider self-connection: `GET /api/nodes` contains `main-server` with `status: online`.
-- Database: the command writes an `unidesk_e2e_markers` row through `docker exec unidesk-database psql`, confirms provider state is stored in PostgreSQL, and probes the public PostgreSQL port with `pg_isready`.
-- Frontend: Playwright opens the public frontend URL, waits for `核心在线`, asserts that `main-server` and `Main Server Provider` are visible, checks the metrics panel, and captures a screenshot under `.state/e2e/`.
+- Public exposure: Docker port summary must show only frontend and provider ingress host mappings; public core and public database probes must fail.
+- Core API: `docker exec unidesk-backend-core` calls internal `GET /api/overview`, which must report `dbReady: true` and at least one online node.
+- Provider self-connection: internal `GET /api/nodes` must contain `main-server` with `status: online`; public provider ingress `/health` must return ok.
+- Database: the command writes an `unidesk_e2e_markers` row through `docker exec unidesk-database psql` and confirms provider state is stored in PostgreSQL.
+- Frontend: Playwright opens the public frontend URL, logs in with the configured account, waits for `核心在线`, asserts that `main-server` and `Main Server Provider` are visible, confirms no raw JSON is visible before clicking `查看原始JSON`, then clicks the explicit raw JSON button and verifies the raw payload appears.
 
-## Public Frontend Rule
+## Frontend JSON Rule
 
-The frontend must not inject `127.0.0.1` as the browser-facing core API URL for public deployments. If a loopback URL is accidentally injected and the page itself is opened from a non-loopback host, `public/app.js` rewrites the API host to `window.location.hostname` as a safety net; however the correct fix is still to set `network.publicHost` correctly in `config.json` and restart the stack.
+The frontend must render JSON data into React controls by default. Raw JSON is allowed only after an explicit `查看原始JSON` user action, and E2E must fail if the initial page exposes raw JSON text or a raw JSON block.
+
+## Public Boundary Rule
+
+The public frontend URL and provider ingress URL are the only public network interfaces. backend-core REST API and PostgreSQL database are Docker-internal only; E2E must prove the historical public core/database ports are not reachable.

+## Component Data Rendering
+
+前端必须把 backend-core 返回的 JSON 渲染为合适的控件：状态徽标、指标卡、表格列、标签 chip、字段摘要、任务结果卡、日志行和表单控件。默认页面禁止暴露裸 JSON、`pre` JSON 或整段 `JSON.stringify` 文本；只有用户明确点击 `查看原始JSON` 按钮后，才允许在弹窗或高级编辑区展示原始 JSON。

+## Login
+
+frontend 提供账号密码登录，默认账号为 `admin`，默认密码为 `Liang6516.`。登录会话使用 frontend 容器签发的 HttpOnly Cookie；浏览器后续只访问同源 frontend API，frontend 再通过 Docker 内网代理 backend-core。

 # Provider Gateway Reference
 
-Provider Gateway 是计算节点侧容器。它只主动连出到 backend-core 的 WebSocket，不要求计算节点有公网 IP，适合 NAT、内网和防火墙后的机器。
+Provider Gateway 是计算节点侧容器。它只主动连出到主 server 暴露的 provider ingress WebSocket，不要求计算节点有公网 IP，适合 NAT、内网和防火墙后的机器。
 
 ## Main Server Self Provider
 
-当前主 server 也运行一个 provider-gateway，`providerId` 固定来自 `config.json` 的 `providerGateway.id`。这让单机环境也能验证完整的分布式调度闭环：frontend 发起任务，core 写数据库并通过 WebSocket 下发，provider gateway 执行后回传状态。

+
+## Provider Ingress
+
+provider ingress 是唯一允许公网暴露的 provider 连接接口，当前由 backend-core 容器的独立端口提供 `/ws/provider` 和 `/health`。backend-core REST API 仍只在 Docker 内网开放，外部计算节点只应连接 provider ingress。
