### Caching Strategy:

```
Request → Check Cache → [Hit] → Return Cached Data (fast)
              ↓
            [Miss]
              ↓
         Rate Limit Check → [Limited] → Return Stale Cache
              ↓                              (graceful degradation)
            [OK]
              ↓
         External API Call → Success → Cache + Return
              ↓
            Failure (429)
              ↓
         Exponential Backoff → Blacklist (3x 429)
              ↓
         Return Stale Cache or Error
```

### Priority Routing:

```
Request for Market Data
    ↓
1. Sort providers by priority (highest first)
2. Filter out blacklisted/rate-limited providers
3. Sort by consecutive_failures (lowest first)
4. Sort by avg_response_time (fastest first)
    ↓
Select first available provider
    ↓
Execute request with timeout
    ↓
[Success] → Update metrics → Reset failure counter
[Failure] → Increment counter → Apply cooldown if needed
[429] → Exponential backoff → Blacklist if 3x
```

## 🐛 TROUBLESHOOTING

### Issue: Build Timeout
**Symptom:** Docker build exceeds 10 minutes  
**Solution:** CPU-only torch should resolve this  
**Verification:** Check requirements.txt has `--extra-index-url` and `torch==2.1.0+cpu`

### Issue: Transformers Not Loading
**Symptom:** AI Models section shows "Not loaded"  
**Solution:** Check HF_TOKEN environment variable  
**Verification:** Ensure `transformers==4.35.0` is installed

### Issue: Status Panel Not Showing Data
**Symptom:** Empty sections or "Loading..." stuck  
**Solution:** Check `/api/system/status` endpoint  
**Verification:** Visit `https://space-url/api/system/status` directly

### Issue: Still Getting 429 Errors
**Symptom:** CoinGecko rate limits in logs  
**Solution:** Check cache is working  
**Verification:** Look for "Cache hit" messages in logs

### Issue: Drawer Not Opening
**Symptom:** Circular button doesn't open drawer  
**Solution:** Check JavaScript console for errors  
**Verification:** Ensure status-drawer.js loaded correctly
