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:

1. Fix MLSafetyError::FeatureExtractionError variant (missing)
2. Remove pub mod parquet_io; from features_old.rs (line 3513)
3. 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:

1. ml/src/safety/mod.rs - Add FeatureExtractionError variant
2. ml/src/features_old.rs - Remove parquet_io module
3. ml/src/features/unified.rs - Fix Decimal conversions

Command to verify:

cargo build -p ml --lib

Command to run tests (after fixes):

cargo test -p ml_training_service --test job_queue_tests --no-fail-fast
