5. brokers::interactive_brokers::tests::broker_client_trait_tests::test_reconnect_interface
   Issue: Error variant mismatch

3-WEEK IMPROVEMENT PLAN:
-------------------------
Week 1: Real-time infrastructure → 80% (DBN parser, WebSocket, Stream)
Week 2: News integration → 70% (Benzinga streaming, historical)
Week 3: Persistence & validation → 70% (Parquet, validation, features)

Expected outcome: 22.53% → ~65% (+42.5% gain)
Effort: ~120 hours, ~100 new tests
