CUB-CI: Consolidate CI — switch to ubuntu-latest with manual Go/Node install

- Remove custom go-react runner label (was inconsistent on PR branches) - Replace with ubuntu-latest + manual Go 1.23 / Node 22 install (actions/setup-go and setup-node don't work with Gitea Act runner) - Remove duplicate build-dev.yaml workflow (already deleted) - All steps: Go test → Go build → npm ci → npm lint → npm build - Docker push on push events only (unchanged)
CUB-CI: Remove redundant build-dev.yaml

+# Control Center Deployment Guide
+
+This document covers the Docker Compose deployment and kiosk configuration for the Control Center Go + React application.
+
+## Quick Start
+
+```bash
+# Start all services (backend, frontend, database)
+docker compose up -d
+
+# View logs
+docker compose logs -f
+
+# Stop all services
+docker compose down
+
+# Stop and remove volumes (database data)
+docker compose down -v
+```
+
+## Architecture
+
+```
+┌─────────────────┐
+│   Frontend      │  Port 3000 (host) → 80 (container)
+│   React + nginx │  Serves SPA, proxies /api/ to backend
+└────────┬────────┘
+         │
+         │ HTTP
+         │
+┌────────▼────────┐
+│   Backend       │  Port 8080 (host) → 8080 (container)
+│   Go HTTP API   │  PostgreSQL-backed REST API
+└────────┬────────┘
+         │
+         │ PostgreSQL
+         │
+┌────────▼────────┐
+│   PostgreSQL    │  Port 5432 (internal only)
+│   Database      │  Persistent volume at /var/lib/postgresql/data
+└─────────────────┘
+```
+
+## Services
+
+### Backend (`go-backend`)
+
+- **Image**: Custom `alpine:latest` with Go binary
+- **Port**: 8080
+- **Build**: Multi-stage from `go-backend/Dockerfile`
+- **Environment Variables**:
+  - `PORT` (default: 8080)
+  - `DATABASE_URL` (PostgreSQL DSN)
+  - `CORS_ORIGIN` (default: `*`)
+  - `LOG_LEVEL` (default: `info`)
+  - `ENVIRONMENT` (default: `development`)
+  - `GATEWAY_URL` (OpenClaw gateway endpoint)
+
+### Frontend (`frontend`)
+
+- **Image**: `nginx:1.27-alpine`
+- **Port**: 80 (internal) → 3000 (host)
+- **Build**: Multi-stage from `frontend/Dockerfile`
+  - Node 22 for build
+  - Nginx 1.27 for serving
+- **Config**: Custom nginx config in `frontend/nginx.conf`
+- **Environment Variables**:
+  - `VITE_API_URL` (passed at build time via Vite config)
+
+### Database (`db`)
+
+- **Image**: `postgres:16-alpine`
+- **Port**: 5432 (internal only)
+- **Volume**: `postgres-data:/var/lib/postgresql/data`
+- **Environment Variables**:
+  - `POSTGRES_USER` (default: `controlcenter`)
+  - `POSTGRES_PASSWORD` (default: `controlcenter`)
+  - `POSTGRES_DB` (default: `controlcenter`)
+
+## Kiosk Mode
+
+For dedicated display installations (e.g., control center dashboard), Chromium can run in kiosk mode.
+
+### Installation
+
+1. **Install the systemd service** (on Debian/Ubuntu with systemd):
+
+```bash
+sudo cp kiosk/control-center-kiosk.service /etc/systemd/system/
+sudo systemctl daemon-reload
+```
+
+2. **Enable auto-start**:
+
+```bash
+sudo systemctl enable control-center-kiosk
+```
+
+3. **Start the service**:
+
+```bash
+sudo systemctl start control-center-kiosk
+```
+
+4. **Check status and logs**:
+
+```bash
+sudo systemctl status control-center-kiosk
+sudo journalctl -u control-center-kiosk -f
+```
+
+### Manual Launch
+
+```bash
+# From project root
+./kiosk/start-kiosk.sh http://localhost:3000
+```
+
+### Uninstall
+
+```bash
+# Stop and disable service
+sudo systemctl stop control-center-kiosk
+sudo systemctl disable control-center-kiosk
+sudo rm /etc/systemd/system/control-center-kiosk.service
+sudo systemctl daemon-reload
+```
+
+### Kiosk Requirements
+
+- **Browser**: `chromium-browser` (install via `apt-get install chromium`)
+- **Display**: X11 session with `DISPLAY=:0`
+- **User**: Must run as a user with X11 access (typically `overseer`)
+- **Permissions**: Read access to the project directory
+
+## Environment Variables Reference
+
+### Backend (`go-backend/.env`)
+
+```bash
+PORT=8080
+DATABASE_URL=postgresql://controlcenter:controlcenter@localhost:5432/controlcenter?sslmode=disable
+CORS_ORIGIN=*
+LOG_LEVEL=info
+ENVIRONMENT=development
+GATEWAY_URL=http://localhost:18789/api/agents
+GATEWAY_POLL_INTERVAL=5s
+```
+
+### Frontend (build-time)
+
+```bash
+VITE_API_URL=http://localhost:8080
+```
+
+### Docker Compose
+
+Set via `services.<name>.environment` in `docker-compose.yml`:
+
+```yaml
+services:
+  backend:
+    environment:
+      - DATABASE_URL=...
+  frontend:
+    environment:
+      - VITE_API_URL=...
+  db:
+    environment:
+      - POSTGRES_USER=...
+      - POSTGRES_PASSWORD=...
+      - POSTGRES_DB=...
+```
+
+## Development
+
+### Local Development (non-Docker)
+
+```bash
+# Backend
+cd go-backend
+go run ./cmd/server/main.go
+
+# Frontend
+cd frontend
+npm install
+npm run dev
+```
+
+### Database Migrations
+
+```bash
+# If using pgx/migrate or similar
+# The database is created automatically on first connection if it doesn't exist
+```
+
+## Troubleshooting
+
+### Backend won't connect to database
+
+```bash
+# Check database container status
+docker compose ps
+
+# View database logs
+docker compose logs db
+
+# Test database connectivity from backend
+docker compose exec backend ping db
+```
+
+### Frontend can't reach backend
+
+```bash
+# Check network connectivity
+docker compose exec frontend ping backend
+
+# Verify backend is running
+docker compose logs backend
+```
+
+### Kiosk browser won't start
+
+```bash
+# Check Chromium installation
+which chromium-browser
+
+# Check X11 forwarding
+echo $DISPLAY
+
+# Manual launch for debugging
+./kiosk/start-kiosk.sh http://localhost:3000
+```
+
+### Port conflicts
+
+If ports 8080, 3000, or 5432 are already in use, modify `docker-compose.yml`:
+
+```yaml
+services:
+  backend:
+    ports:
+      - "8081:8080"  # Change host port
+  frontend:
+    ports:
+      - "3001:80"    # Change host port
+```
+
+## Production Considerations
+
+1. **HTTPS**: Add a reverse proxy (nginx/Traefik) for SSL termination
+2. **Database security**: Use strong passwords, enable SSL
+3. **CORS**: Restrict `CORS_ORIGIN` to production domain
+4. **Logs**: Configure log aggregation (e.g., ELK, Loki)
+5. **Backups**: Regular PostgreSQL volume backups
+6. **Monitoring**: Add health checks and alerting
+

+# Control Center — Architecture Context
+
+## Current State
+
+The Control Center backend uses a **dual-path gateway client** architecture:
+
+- **Primary path**: WebSocket client (`gateway.WSClient`) connects to the OpenClaw gateway using WS protocol v3. It handles handshake, initial sync (agents.list + sessions.list RPCs), live event routing (sessions.changed, presence, agent.config), and automatic reconnection with exponential backoff.
+- **Fallback path**: REST poller (`gateway.Client`) polls the gateway `/api/agents` endpoint on an interval. It only activates if the WS client fails to connect within 30 seconds of startup.
+
+## Live Gateway Connection
+
+### Startup Sequence
+1. Both WS client and REST client start concurrently
+2. REST client waits 30s for WS readiness signal (`wsReady` channel)
+3. If WS connects successfully → REST client stands down (logs "using WS — REST poller standing down")
+4. If WS fails within 30s → REST client falls back to polling (logs "WS not ready — falling back to REST polling")
+5. If no WS client configured → REST client polls immediately
+
+### WebSocket Client (Primary)
+- Config: `WS_GATEWAY_URL` (default: `ws://host.docker.internal:18789/`), `OPENCLAW_GATEWAY_TOKEN`
+- Protocol: v3 handshake (challenge → connect → hello-ok)
+- Initial sync: `agents.list` + `sessions.list` RPCs → persist → merge → broadcast `fleet.update`
+- Live events: `sessions.changed`, `presence`, `agent.config`
+- Reconnection: exponential backoff (1s → 2s → 4s → ... → 30s max)
+
+### REST Poller (Fallback)
+- Config: `GATEWAY_URL` (default: `http://host.docker.internal:18789/api/agents`), `GATEWAY_POLL_INTERVAL` (default: 5s)
+- Only used when WS is unavailable
+- Polls the `/api/agents` endpoint and syncs agent status changes
+
+### Wiring
+```
+main.go
+  ├── wsClient = NewWSClient(...)
+  ├── restClient = NewClient(...)
+  ├── wsClient.SetRESTClient(restClient)  // WS notifies REST on ready
+  ├── restClient.SetWSClient(wsClient)    // REST defers to WS
+  ├── go wsClient.Start(ctx)              // primary
+  └── go restClient.Start(ctx)            // fallback (waits for WS)
+```
+
+## Key Design Decisions
+- **Push over poll**: WS is preferred for real-time updates; REST is a safety net
+- **DB first, then SSE**: All event handlers persist to DB before broadcasting
+- **Graceful degradation**: System works without WS; REST provides basic functionality
+- **No hard dependency on REST /api/agents**: If WS is connected, REST endpoint is never called
