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
