Wave 3 Agent 10: Quick Reference
Status: ✅ PARTIAL SUCCESS - Fixed target errors, ML crate has unrelated issues
🎯 What We Fixed
1. DQN Trainable Adapter ✅
File: ml/src/dqn/trainable_adapter.rs (Line 219-230)
// Vec → HashMap for safetensors save
let mut tensors: HashMap<String, Tensor> = HashMap::new();
let tensors_refs: HashMap<_, _> = tensors.iter().map(|(k, v)| (k.as_str(), v.clone())).collect();
candle_core::safetensors::save(&tensors_refs, &safetensors_path)
2. MAMBA Trainable Adapter ✅
File: ml/src/mamba/trainable_adapter.rs
Fix 1 (Line 253): Accuracy field
accuracy: self.metadata.training_history.last().and_then(|e| e.accuracy),
Fix 2 (Line 271-281): Async runtime
let runtime = tokio::runtime::Runtime::new().map_err(|e| MLError::ModelError(...))?;
runtime.block_on(async { model_clone.save_checkpoint(checkpoint_path).await })?;
3. Feature Imports ✅
File: ml/src/inference.rs (Line 30)
use crate::features_old::UnifiedFinancialFeatures;
⏸️ Blocked: Can't Run Tests
Why: ML crate has 94 compilation errors in unrelated modules
Next Steps:
- Fix
MLSafetyError::FeatureExtractionErrorvariant (missing) - Remove
pub mod parquet_io;fromfeatures_old.rs(line 3513) - Fix Decimal → f64 conversions in
features/unified.rs
📊 Results
- ✅ 3/3 target files fixed (DQN, MAMBA, imports)
- ❌ 0/16 tests run (blocked by ML crate errors)
- ⏸️ 94 errors remain (in dependencies)
🔄 Next Agent
Mission: Fix ML crate compilation errors Priority:
ml/src/safety/mod.rs- Add FeatureExtractionError variantml/src/features_old.rs- Remove parquet_io moduleml/src/features/unified.rs- Fix Decimal conversions
