    "build": "The chat app is built and works locally, and the server I started for testing is stopped. All 4 automated tests pass, and I also checked the UI, posting, history and a WebSocket round-trip with curl and a small client script against a running server.\n\n**Stack:** Node.js 20+ using the built-in `http` module and the `ws` library for WebSockets. There's no build step and no database. The UI is a single page, `public/index.html`, in plain HTML/JS.\n\n**What it does:**\n- **Web UI (`GET /`):** you pick a display name and a room, either in the form or with `/?room=general`. It loads recent history and connects over WebSocket, using `wss://` automatically on https. It also shows who's online and reconnects on its own if the connection drops.\n- **WebSocket (`GET /ws?room=&user=`):** on connect the server sends the room's history and the list of online users. Sending `{\"type\":\"message\",\"text\":...}` broadcasts the message in the required shape (`id`, `room`, `user`, `text`, `ts`) to everyone in that room, including the sender. Invalid messages get a `{\"type\":\"error\",...}` reply.\n- **Server-Sent Events:** both endpoints from the spec work too. `GET /api/rooms/<room>/events` streams messages, and `POST /api/rooms/<room>/messages` returns `201`. Messages from either side reach both WebSocket and SSE clients.\n- **History (`GET /api/rooms/<room>/messages`):** returns up to the last 50 messages, oldest first.\n- **Validation:** text must be 1\u20131000 characters and not just spaces; names are 1\u201350 characters. Room names are limited to 1\u201364 letters, digits, `_`, `.` or `-`, which is my choice rather than part of the spec. Bad requests over HTTP get `400`.\n- `GET /healthz` is a health check for Render.\n\n**Tests (`test/server.test.js`):** they cover the WebSocket broadcast and room isolation, 4 clients sending 20 messages at once, invalid input, the 50-message history limit, the SSE stream and `POST` returning `201`.\n\n**One limitation:** messages are kept in memory only. They're lost when the server restarts and aren't shared between copies of it, so `render.yaml` sets it to run as a single instance. If history needs to survive restarts, Postgres or Redis would be the next step.\n\n**To run it:**\n```sh\nnpm install\nnpm start        # listens on $PORT, default 3000 \u2192 http://localhost:3000/?room=general\nnpm test\n```\n\n**For deploying:** `render.yaml` defines a Node web service on the free plan: `npm ci` to build, `npm start` to run, `/healthz` as the health check. I also set up a local git repo with one commit; nothing has been pushed.",
    "deploy": "The chat app is live on Render's free plan at **https://adb-cg693-realtime-web.onrender.com**, and I tested every requirement through that public URL.\n\n**How it's deployed:** there was no GitHub account available, so I couldn't deploy from a git repo. Instead, the service (`srv-db7pqp0u01pc739ltang`) runs Render's free tier with the public `node:24-alpine` image. The app code is packed into an environment variable and unpacked when the service starts, with start command `node -e eval(process.env.BOOT)`. The first deploy failed because Render didn't accept the quoted shell start command I gave it; the second worked. To ship code changes, run `deploy/redeploy.sh`. Cost is $0/month, and nothing needed a person, so `human_steps` is empty.\n\n**Results through the public URL:**\n- The UI loads.\n- 15 messages sent at the same time by 3 WebSocket clients over `wss://` reached all 3 clients, including each sender, within about 160 ms.\n- A client in another room got none of them.\n- Invalid WebSocket messages got a `{\"type\":\"error\"}` reply.\n- Over HTTP, empty text, 1001-character text and missing text all got `400`; a 1000-character message got `201`.\n- A message sent with `POST` reached both the Server-Sent Events stream and the WebSocket clients.\n- History returns the latest 50 messages, oldest first.\n\n**Limitations (also in `deployment.json` notes):**\n- **Lost history:** messages are kept in memory only, so history disappears whenever the service restarts or is redeployed.\n- **Single instance:** it must run as one copy, because messages aren't shared between copies.\n- **Free-plan sleep:** the service sleeps after about 15 minutes with no traffic. The next visitor waits roughly 30\u201360 seconds, and open connections drop when it goes to sleep (the UI reconnects on its own). Render's Starter plan, about $7/month, keeps it always on.\n\n`deployment.json` lists the service with `realtime` set to `{\"transport\": \"websocket\", \"url\": \"wss://adb-cg693-realtime-web.onrender.com/ws\"}`. I didn't create any new credentials, so there's no `.env`. The deploy files and `deployment.json` are committed to the local git repo."

Verified through the public URL: UI 200, wss broadcast to all room clients incl. sender (15 concurrent messages to 3 clients in ~160 ms), room isolation, invalid WS messages get type=error, HTTP 400 for empty/1001-char/missing text, 201 for 1000 chars, SSE delivery, history capped at 50 oldest-first."
