- Updated 15+ test functions with proper Result returns
- Fixed meta-labeling, triple barrier, sample weights tests

Agent 7 - Training Pipeline:
- Added comprehensive config re-exports to training_pipeline.rs
- Created DataProcessingConfig struct
- Extended enum variants (MissingDataHandling, OutlierDetectionMethod)
- Fixed training pipeline tests: 94 errors → 0
- Fixed training_pipeline_demo example

Agent 8 - Parquet Persistence:
- Enabled parquet_persistence module
- Fixed ParquetMarketDataEvent schema (8 fields, not 12)
- Updated imports to trading_engine::types::metrics
- Fixed storage_test.rs config import conflicts
- Removed non-existent bid/ask price/size fields

Agent 9 - Trading Engine:
- Fixed 9 files with 36 errors → 0
- Updated event_types.rs decimal macros
- Fixed SIMD intrinsic imports
- Fixed account_manager and order_manager test imports
- Fixed CommonError variant usage
- Fixed event_processing_demo example

Agent 10 - Risk Management:
- Fixed 8 files with 29 errors → 0
- Added num_cpus dependency to config
- Fixed AssetClass import (config::asset_classification)
- Fixed MarketCapTier import paths
- Updated position tracker method names (update_position_sync)
- Fixed EnhancedRiskPosition field access patterns
- Fixed type conversions (Price::from_f64, Quantity::from_f64)

Agent 11 - Adaptive Strategy:
- Fixed 2 example files
- Fixed 42 errors (60 → 18)
- Added tracing-subscriber dependency
- Fixed MarketRegime variants
- Fixed async/await patterns
- Fixed RiskConfig, RegimeConfig field mismatches
- 18 errors remain for Wave 13

Agent 12 - Storage & Verification:
- Fixed 3 storage errors → 0
- Updated S3Config schema in tests
- Verified workspace compilation: 66 errors remaining
- Generated comprehensive reports
- 24/26 storage tests passing (92.3%)

Key Technical Fixes:
1. Configuration types: Proper imports from config::data_config
2. Type safety: Price/Decimal conversions with from_f64()
3. Async patterns: Proper .await usage
4. Import organization: Canonical paths from common crate
5. Test infrastructure: Reusable test_common module
6. Error handling: Result return types on test functions

Remaining Work (66 errors):
- Adaptive-strategy: 58 errors (88% of remaining)
- Trading engine: 6 errors (hidden behind adaptive-strategy)
- Config examples: 2 errors (non-critical)

Next: Wave 13 to fix remaining 66 errors
