## 🐛 6 Critical Bugs Prevented

This template documents and prevents 6 critical bugs that typically cause failures:

1. **Cookie Format Mismatch**  
   Problem: Different cookie formats not normalized  
   Solution: Implement cookie parser that handles all formats

2. **UUID Resolution Bug**  
   Problem: Missing or invalid UUIDs in requests  
   Solution: Validate and generate UUIDs properly

3. **SSE Parsing Failures**  
   Problem: Malformed SSE data crashes parser  
   Solution: Robust parser with error recovery

4. **Session Expiration**  
   Problem: Session expires mid-request, no recovery  
   Solution: Detect 401/403, refresh, retry

5. **Rate Limiting**  
   Problem: 429 responses cause immediate failure  
   Solution: Exponential backoff with jitter

6. **Timeout Handling**  
   Problem: Requests hang indefinitely  
   Solution: Enforce 120s timeout with cleanup

**Each bug has**: Problem description + Solution + Test case
