shadowdao eba5a2a38e security(relay): harden internet-facing relay server
Closes the account-takeover chain and related issues found in audit:

- WS auth brute-force protection: per-session lockout (authThrottle) + per-
  socket failure cap that closes the socket (1008); applied to both web-client
  and desktop auth. Failed auth no longer leaves the socket open for unlimited
  guesses.
- WS upgrades now pass an IP-based rate limiter and Origin allowlist before
  handleUpgrade (previously bypassed all HTTP middleware); trust proxy set so
  limiting keys on the real client IP.
- /health no longer leaks live session IDs (counts only).
- .env.example rate-limit fixed (900000ms / 300) from the accidental ~11k rps.
- Credentials moved out of URLs into the X-MacroPad-Password header; images
  fetched via header + blob URLs; login stores creds in sessionStorage.
- Session creation bounded (max sessions, min password length) and TTL-pruned;
  session store writes are now atomic (temp+rename) and debounced.
- Session IDs lengthened to 12 chars with rejection sampling (no modulo bias).
- Enable helmet CSP; restrict CORS to configured origins.
- Request IDs use crypto.randomUUID; drop postinstall build hook and uuid dep.
- Uniform response for unknown session IDs (removes enumeration oracle).

# MacroPad Relay Server - Deployment Guide
## Cloud Node Container Deployment
For AnHonestHost cloud-node-container deployment:
### 1. Build Locally
```bash
cd /home/jknapp/code/macropad/macropad-relay
npm install
npm run build # required: the build is no longer triggered automatically on install
```
> Note: the `postinstall` build hook was removed. Always run `npm run build`
> explicitly (locally or in CI) after `npm install` to produce `dist/`.
### 2. Prepare Deployment Package
The build outputs to `dist/` with public files copied. Upload:
```bash
# Upload built files to your node container app directory
rsync -avz --exclude 'node_modules' --exclude 'src' --exclude '.git' \
dist/ package.json public/ \
user@YOUR_SERVER:/path/to/app/
```
### 3. On Server
The cloud-node-container will automatically:
- Install dependencies from package.json
- Start the app using PM2
- Configure the process from package.json settings
### 4. Create Data Directory
```bash
mkdir -p /path/to/app/data
```
## Directory Structure on Server
```
app/
├── index.js # Main entry (compiled)
├── config.js
├── server.js
├── services/
├── handlers/
├── utils/
├── public/
│ ├── login.html
│ └── app.html
├── data/
│ └── sessions.json # Created automatically
└── package.json
```
## Update After Code Changes
```bash
# On local machine:
cd /home/jknapp/code/macropad/macropad-relay
npm run build
rsync -avz --exclude 'node_modules' --exclude 'src' --exclude '.git' --exclude 'data' \
dist/ package.json public/ \
user@YOUR_SERVER:/path/to/app/
# On server - restart via your container's control panel or:
pm2 restart macropad-relay
```
## Environment Variables
Set these in your container configuration:
- `PORT` - Server port (default: 3000)
- `DATA_DIR` - Data storage path (default: ./data)
- `NODE_ENV` - production or development
- `LOG_LEVEL` - info, debug, error
## Test It Works
```bash
# Test health endpoint
curl http://localhost:3000/health
# Should return (counts only - no session ids are exposed):
# {"status":"ok","desktops":0,"webClients":0,"uptime":1.23}
```
## Nginx/Reverse Proxy (for HTTPS)
```nginx
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
# WebSocket timeout (24 hours)
proxy_read_timeout 86400;
}
```
## Troubleshooting
**Check logs:**
```bash
pm2 logs macropad-relay
```
**Check sessions:**
```bash
cat /path/to/app/data/sessions.json
```
**Port in use:**
```bash
lsof -i :3000
```
