═══════════════════════════════════════════════════════════
🔧 CRITICAL CONFIGURATION POINTS
═══════════════════════════════════════════════════════════
1. NPM WebSocket Configuration (CRITICAL!)
# In NPM Proxy Host for Socket.IO:
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 7d;
proxy_send_timeout 7d;
Without this: Socket.IO won't connect!
2. Session Affinity (3 Layers)
# Layer 1: NPM
ip_hash;
# Layer 2: K8s Service
sessionAffinity: ClientIP
# Layer 3: K8s Ingress
nginx.ingress.kubernetes.io/affinity: "cookie"
Without this: Users get disconnected!
3. FoundationDB Cluster File
# In all applications:
fdb.api_version(710)
db = fdb.open() # Reads /var/fdb/fdb.cluster
Without this: Can't connect to database!
4. Socket.IO Redis Adapter (Multi-Pod)
// In Socket.IO server:
const redisAdapter = require('@socket.io/redis-adapter');
io.adapter(redisAdapter(pubClient, subClient));
Without this: Messages only work within one pod!

🐛 COMMON ISSUES & SOLUTIONS
═══════════════════════════════════════════════════════════
Issue: theia won't start
# Check logs
docker-compose logs theia-ide
# Common causes:
- FoundationDB not ready → Wait for health check
- Missing cluster file → Check volume mount
- Port conflict → Change THEIA_PORT
Issue: MCP servers not connecting
# Test connectivity
docker-compose exec theia-ide curl http://mcp-analysis:8001/health
# Common causes:
- Network isolation → Check docker-compose network
- Wrong URL in config → Check MCP_*_URL env vars
- MCP server crashed → Check logs
Issue: File changes not detected
# Check Monitor logs
docker-compose exec theia-ide tail -f /var/log/coditect/monitor.log
# Common causes:
- Monitor not running → Check process
- Ignore pattern too broad → Review monitor.yml
- Volume mount issues → Check permissions
Issue: Agents not responding
# Check Command logs
docker-compose exec theia-ide tail -f /var/log/coditect/command.log
# Common causes:
- llm API key invalid → Check .env
- MCP server timeout → Increase timeout
- Workflow not triggered → Check trigger config
