## Critical Issues Documented

### Priority 0 (CRITICAL) - Must Fix Before Production

1. **WebSocket Protocol Mismatch**
   - Client expects: `chunk`, `message.done`
   - Backend sends: `message_chunk`, `message_complete`
   - Impact: Chat functionality completely broken
   - Effort: 30 minutes

2. **Client Message Type Mismatch**
   - Frontend sends: `type: "message.send"`
   - Backend expects: `type: "message"`
   - Impact: Outgoing messages blocked
   - Effort: 15 minutes

3. **No WebSocket Authentication**
   - Current: Anyone can connect
   - Required: JWT token validation
   - Impact: Security vulnerability
   - Effort: 2 hours

### Priority 1 (HIGH) - Should Fix Soon

4. **Hardcoded WebSocket URL**
   - Current: Hard-coded to production
   - Impact: Cannot test locally
   - Effort: 30 minutes

5. **No Error Notifications**
   - Current: Errors log to console only
   - Impact: Users don't see errors
   - Effort: 2 hours

6. **Last Message Preview Not Verified**
   - Impact: Conversation list doesn't show previews
   - Effort: 1 hour
