## SECURITY
```
AUTHENTICATION FLOW
───────────────────
1. User logs in
2. Backend verifies credentials
3. Backend generates JWT token
4. Frontend stores in localStorage
5. Every API request includes:
Authorization: Bearer <token>
6. Backend validates token
7. If valid → allow request
If invalid → 401 response
8. Frontend intercepts 401 → redirect to login
WEBSOCKET AUTHENTICATION
─────────────────────────
1. Client connects with:
auth: { token: JWT }
2. Server validates token
3. If valid → establish connection
If invalid → reject connection
4. All WebSocket messages
associated with user_id
from token
```
## REAL-TIME FEATURES
```
TYPING INDICATORS
─────────────────
User types → Start timeout
Emit typing_start
Backend broadcasts to channel
Other users see "User is typing..."
After 2 seconds of no typing
Emit typing_stop
Indicator disappears
ONLINE STATUS
─────────────
User connects → WebSocket established
User marked online
Broadcast user_online
User disconnects/closes tab
User marked offline
Broadcast user_offline
```
## AI INTEGRATION (@grimlock)
```
USER MENTIONS AI
────────────────
User types: "@grimlock what is UTILEN?"
Message saved to DB
Broadcast to users (instant)
Backend detects @grimlock

│ 4. Get AI response │
│ │
│ 5. Save to DB with │
│ is_ai_response=true │
│ │
│ 6. Broadcast via │

```
## WHAT MAKES THIS SPECIAL
1. **AI-Native**
- AI is not bolted on
- AI participates in every conversation
- Context-aware responses
- Company knowledge integrated
2. **Real-Time First**
- WebSocket for everything
- No polling, no delays
- Typing indicators
- Instant presence
3. **Production-Ready**
- TypeScript throughout
- Error handling
- Loading states
- Optimistic updates
- Docker deployment
4. **Developer-Friendly**
- Clear separation of concerns
- Zustand for state
- Axios for HTTP
- Socket.IO for WS
- Tailwind for styling
5. **Scalable Architecture**
- Stateless backend
- JWT auth (horizontal scaling)
- Room-based WebSocket
- Efficient DB queries
