    "build": "The chat app is built and works locally. All 6 automated tests pass, I checked every endpoint by hand with curl, and the Docker image builds and answers its health check. I've stopped the servers and the container I started.\n\n**Stack:** Node.js with the built-in `http` module and one dependency, `ws`, for WebSockets. There's no build step. The web UI is a single page in `public/index.html`.\n\n**What it does:**\n- **Web UI:** `GET /` lets you pick a display name and a room (for example `/?room=general`). It loads the room's history, sends messages over the WebSocket, shows who's online, and reconnects on its own if the connection drops. It uses `wss://` automatically when the page is served over HTTPS.\n- **WebSocket:** `GET /ws?room=&user=` takes `{\"type\":\"message\",\"text\":\u2026}` and broadcasts the message, in the shape `TASK.md` asks for, to everyone in that room including the sender. It also sends `history`, `presence` and `error` messages. Invalid text gets an `{\"type\":\"error\"}` reply.\n- **History:** `GET /api/rooms/<room>/messages` returns the latest 50 messages, oldest first.\n- **Server-Sent Events:** I implemented this too. `GET /api/rooms/<room>/events` streams messages, and `POST /api/rooms/<room>/messages` sends one and returns `201`, or `400` if it's invalid.\n- **Limits:** messages must be 1\u20131000 characters, display names 1\u201350, and room names can only use letters, digits, `_`, `.` and `-` (up to 64).\n- **Health check:** `GET /health`.\n\n**The tests cover:** delivery to everyone in a room including the sender, isolation between rooms, 5 clients sending 50 messages at once with all of them delivered, rejection of invalid messages over both WebSocket and HTTP, the 50-message history cap and order, and the SSE stream.\n\n**Run:**\n```\nnpm install\nnpm start      # listens on $PORT, default 8080\nnpm test\n```\nOr with Docker: `docker build -t chat-rooms . && docker run -p 8080:8080 chat-rooms`\n\n**For deployment:** the included `Dockerfile` suits DigitalOcean App Platform; point the health check at `/health`. Message history is kept in memory, so it's lost on restart and the app must run as a single instance.",
    "deploy": "The chat app is live at **https://adb-wf7uo-realtime-5cs45.ondigitalocean.app** over HTTPS, and every requirement in `TASK.md` worked when I tested it through that URL.\n\n**What I deployed (about $5/month):**\n- **Container registry:** `adb-wf7uo-realtime` on the free starter tier, in nyc3. I built the Docker image locally and pushed it there as `adb-wf7uo-realtime-web:v1`.\n- **App Platform app:** `adb-wf7uo-realtime` (id `d1340407-bcac-4f7c-8ded-82851d8e8b53`). It runs one instance of the smallest paid size, `apps-s-1vcpu-0.5gb`, which costs $5/month. DigitalOcean provides the HTTPS certificate, and the health check uses `/health`. The app configuration is saved in `.do/app.yaml`.\n\n**What I tested on the public URL:**\n- The web UI returns 200.\n- Posting a message over HTTP returns `201`; empty text and text over 1000 characters both return `400`.\n- The history endpoint returns the room's messages in the expected shape.\n- **WebSocket (`wss://\u2026/ws`):** four clients sent 20 messages at the same time, and every client received all 20 within 60 ms. An invalid message got an `error` reply, and a client in another room received nothing.\n- **Server-Sent Events:** the stream delivered a posted message.\n\n`deployment.json` is written, with `realtime` set to WebSocket at `wss://adb-wf7uo-realtime-5cs45.ondigitalocean.app/ws`. Nothing needed a person, so `human_steps` is empty. I didn't create any credentials, so there's no `.env` file; I added `.env` to `.gitignore` anyway.\n\n**Limitation:** message history is kept in memory. It's wiped on every redeploy or restart, and the app has to stay at one instance, because a second instance wouldn't share rooms with the first."
