All 6 automated tests pass, and I also ran it in its Docker container and checked it with curl. Nothing is deployed yet, and I stopped and removed the container afterwards.\n\n**Stack:** Node.js with Express, and the `ws` library for WebSockets. Messages are kept in memory, with the last 50 per room. Everything is in one process, so `server.js` holds the whole server and `public/index.html` is the web page.\n\n**What's covered:**\n- **Web page (`GET /?room=general`):** you pick a display name and a room, see the room's recent messages, and new messages appear live. It also lists who is online and reconnects on its own if the connection drops.\n- **WebSocket (`/ws?room=\u2026&user=\u2026`):** each new client first gets the room's history. Messages go to everyone in that room, including the sender. An invalid message gets an `{\"type\":\"error\"}` reply and is not saved.\n- **Server-Sent Events:** I built this option too. Messages are posted with `POST /api/rooms//messages`, which returns `201`, or `400` for an empty, too-long or malformed message. They are streamed from `GET /api/rooms//events`.\n- **History:** `GET /api/rooms//messages` returns the latest 50, oldest first.\n- **Health check:** `GET /healthz`, for the hosting platform to check the app is up.\n\n**Tests:** they confirm that a broadcast reaches the sender and the other user, that rooms are kept separate, that five people sending at once all get every message, that the 50-message history limit holds, that bad messages are rejected over HTTP and WebSocket, and that the event stream delivers messages.\n\n**Limitation:** because messages and connections live in memory, the app must run as exactly one instance, and history is lost whenever it restarts. That is acceptable for a hobby club. Running several instances would need a shared store such as Redis.\n\n**Run it:**\n```\nnpm install && npm start # listens on $PORT, default 8080\nnpm test\ndocker build -t chat . && docker run -p 8080:8080 chat\n```\n\n**For step 2:** there's a `Dockerfile` and a DigitalOcean App Platform config in `.do/app.yaml`. It is set to one instance, port 8080 and the `/healthz` check. App Platform handles WebSockets, and the web page switches to `wss://` automatically when served over HTTPS.", "deploy": "The chat app is live at **https://adb-gn1e1-realtime-4oyp9.ondigitalocean.app**, and every requirement in `TASK.md` worked when I tested it through that URL.\n\n**What's running**\n- **Container registry** `adb-gn1e1-realtime`: holds the app's Docker image as `adb-gn1e1-realtime-web:v1`. It's on the free starter tier.\n- **App Platform app** `adb-gn1e1-realtime`: one instance of the smallest size, $5/month, with HTTPS provided by DigitalOcean. The real-time endpoint is `wss://adb-gn1e1-realtime-4oyp9.ondigitalocean.app/ws`.\n- **Estimated total:** about $5/month.\n\n**What I tested on the live site**\n- The web page loads.\n- With four users connected to one room and all sending at the same moment, every user received all four messages within 1.5 seconds.\n- A user in a different room received none of them.\n- Empty messages and messages over 1000 characters are rejected: `400` over HTTP, and an error reply over WebSocket.\n- The history API returns the room's messages.\n- The Server-Sent Events alternative also works: posting returns `201`, and the message arrives on both the event stream and WebSocket clients.\n\n**Limitation:** messages are kept in memory, so the app must stay at one instance. Room history is wiped whenever it restarts or is redeployed.\n\nNothing needed a person, so `human_steps` is empty. I didn't create any new credentials, so there's no `.env`; logging in to the registry used the existing access token.\n\n`deployment.json` is written, and the deployment config is in `.do/app.yaml`.
