🐛 Bugs Fixed

Bug #1: Asset Class Region Mismatch

• Test: test_select_universe_by_asset_class
• Issue: Test failed because 6E.FUT (Currencies) is in Global region, not NorthAmerica
• Fix: Added criteria.regions = vec![Region::Global]
• Status: ✅ FIXED

Bug #2: HashSet with AssetClass

• Test: test_multiple_asset_classes
• Issue: Compilation error - AssetClass doesn't implement Hash
• Fix: Use format!("{:?}", asset_class) instead of direct enum
• Status: ✅ FIXED

• Volatility filter working correctly
• Asset class filter working correctly
• Region filter working correctly
• Market cap filter working correctly
• Empty universe handling (error)
• Single instrument selection
• All instruments selection
• Invalid criteria validation
• Deterministic results
• Reproducible metrics
• Performance <1s (actual: <100ms)
• Real symbols (ES.FUT, NQ.FUT, ZN.FUT, 6E.FUT, CL.FUT)
• Database storage/retrieval
• Universe updates

🔮 Future Work

Correlation Filtering (Not Implemented)

• Universe module has max_correlation field but no implementation
• Requires historical price data and correlation matrix
• Recommended for Wave 15+ when historical data pipeline ready

Caching Layer (Not Needed Yet)

• Current performance (2-11ms) is excellent
• Caching would reduce to <1ms but not necessary for MVP
• Consider for high-frequency universe queries (>1000/sec)

Dynamic Instrument Discovery

• Current: Hardcoded 5 instruments
• Future: Query market data APIs for available instruments
• Benefits: Scalability to thousands of instruments
