## Critical Issues Requiring Immediate Attention

### 1. Authentication Missing on ALL Backend Routes
- **Impact:** Complete system compromise possible
- **File:** All routes in `src/routes/`
- **Fix:** Add auth middleware to all endpoints

### 2. Hardcoded Google Sheets Credentials
- **Impact:** Data exposure via public repo
- **File:** `src/routes/leads.js:460-461`
- **Fix:** Move to environment variables

### 3. User ID Header Spoofing
- **Impact:** Impersonate any user
- **Files:** achievements.js, xp.js, coaching.js, etc.
- **Fix:** Validate from JWT, not client headers

### 4. No Timeouts on External API Calls
- **Impact:** Requests hang indefinitely, resource exhaustion
- **Files:** ai.js, slack.js, perplexity.js, platformSync.js
- **Fix:** Add AbortSignal.timeout() to all fetch calls

### 5. Memory Leaks in Frontend
- **Impact:** Browser crashes, audio locks
- **Files:** LiveCopilot.jsx, RealtimeContext.jsx
- **Fix:** Proper cleanup in useEffect returns

### 6. Missing Foreign Keys in Database
- **Impact:** Orphan records, data inconsistency
- **Tables:** user_xp, user_achievements, xp_history, etc.
- **Fix:** Add FK constraints with CASCADE
