## Known Issues & Resolutions

### High Priority (Block Production Deployment)

#### Issue 1: Feature 223 Sharpe Ratio Edge Case ⚠️
- **File**: `/home/jgrusewski/Work/foxhunt/ml/src/features/regime_adaptive.rs:217`
- **Test**: `test_feature_223_regime_conditioned_sharpe`
- **Issue**: Sharpe ratio returns 0.0 when volatility is zero
- **Root Cause**: Division by zero when std=0
- **Fix**: Add minimum data check + std=0 handling
- **Time**: 15 minutes
- **Impact**: Feature 223 will return NaN in low-volatility periods
- **Resolution**:
  ```rust
  // Add zero-check before division
  if std_dev < 1e-8 || count < 2 {
      return 0.0; // Not enough data or zero volatility
  }
  let sharpe = (mean_return - risk_free_rate) / std_dev;
  ```

#### Issue 2: 6-Regime Transition Matrix Initialization ⚠️
- **File**: `/home/jgrusewski/Work/foxhunt/ml/src/regime/transition_matrix.rs:45`
- **Test**: `test_regime_transition_features_new_6_regimes`
- **Issue**: Matrix initialized with 4 regimes, not 6
- **Root Cause**: `RegimeTransitionMatrix::new()` defaults to 4 regimes
- **Fix**: Update constructor to accept `num_regimes` parameter
- **Time**: 20 minutes
- **Impact**: Cannot support custom regime sets (e.g., 6-regime model)
- **Resolution**:
  ```rust
  impl RegimeTransitionMatrix {
      pub fn new(num_regimes: usize, alpha: f64) -> Self {
          // Initialize with N x N matrix instead of hardcoded 4x4
          Self {
              matrix: vec![vec![0.0; num_regimes]; num_regimes],
              counts: vec![vec![0; num_regimes]; num_regimes],
              num_regimes,
              alpha,
              // ...
          }
      }
  }
  ```

**Total High Priority Fix Time**: 35 minutes

### Low Priority (Test Data Generation Issues)

#### Issue 3: Ranging Detection Test Data ⚠️
- **Test**: `test_ranging_detection`
- **Issue**: No ranging bars detected in test data
- **Root Cause**: Test data has trending component, ADX >25
- **Fix**: Generate tight mean-reverting data with ±0.1% moves
- **Time**: 15 minutes

#### Issue 4: Ranging Market Detection ⚠️
- **Test**: `test_ranging_market_detection`
- **Issue**: ADX too high (46.8 vs. <25 expected)
- **Root Cause**: Test data has sustained directional moves
- **Fix**: Generate alternating +/- moves to neutralize ADX
- **Time**: 20 minutes

#### Issue 5: High Volatility Regime Detection ⚠️
- **Test**: `test_get_volatility_regime_high`
- **Issue**: Not detecting elevated volatility regime
- **Root Cause**: Test data volatility too low (±1% vs. ±10% needed)
- **Fix**: Generate ±10% price swings
- **Time**: 15 minutes

#### Issue 6: Low Volatility Regime Detection ⚠️
- **Test**: `test_get_volatility_regime_low`
- **Issue**: Not detecting low volatility regime
- **Root Cause**: Test data volatility too high (±0.5% vs. ±0.01% needed)
- **Fix**: Generate ±0.01% ranges (near-flat price action)
- **Time**: 10 minutes

**Total Low Priority Fix Time**: 60 minutes

**Grand Total Fix Time**: 95 minutes (1.6 hours)

### Production Blockers Resolved (E21)

#### Blocker 1: Trading Service Compilation Error (P0 CRITICAL) ✅ RESOLVED
- **Issue**: `get_regime_state` and `get_regime_transitions` methods outside trait block
- **Impact**: Trading Service failed to compile
- **Resolution**: Moved methods inside `impl TradingRepository for PgTradingRepository` trait block
- **Time**: 15 minutes (E21)
- **Status**: ✅ **RESOLVED** (2.86s clean build)

#### Blocker 2: SQLX Cache Missing (P1 HIGH) ✅ RESOLVED
- **Issue**: 6 SQLX queries not cached for offline compilation
- **Impact**: CI/CD builds failed without database access
- **Resolution**: Generated SQLX cache files (`.sqlx/*.json`) using `cargo sqlx prepare`
- **Time**: 10 minutes (E21)
- **Status**: ✅ **RESOLVED** (6 cache files generated)

2. **Feature Extraction**: Generate 225-feature dataset
   ```bash
   cargo run --release --example generate_training_data \
     --input-dir data/raw \
     --output-dir data/features_225 \
     --features 225
   ```
3. **Data Validation**: Verify feature quality (no NaN/Inf, correct ranges)
   ```bash
   cargo run --release --example validate_features \
     --data-dir data/features_225
   ```

#### Week 3-4: Model Retraining (4 Models)

##### Model 1: MAMBA-2 (Primary Model)
- **Training Time**: ~1.86 minutes (GPU RTX 3050 Ti)
- **Command**:
  ```bash
  cargo run -p ml --example train_mamba2_dbn --release -- \
    --features 225 \
    --data-dir data/features_225 \
    --epochs 100 \
    --batch-size 32
  ```
- **Expected Improvement**: +15-25% Sharpe (1.2 → 1.5-1.8)

##### Model 2: DQN (Reinforcement Learning)
- **Training Time**: ~15 seconds (GPU RTX 3050 Ti)
- **Command**:
  ```bash
  cargo run -p ml --example train_dqn --release -- \
    --features 225 \
    --data-dir data/features_225 \
    --episodes 1000
  ```
- **Expected Improvement**: +20-30% win rate (50% → 60-65%)

##### Model 3: PPO (Policy Optimization)
- **Training Time**: ~7 seconds (GPU RTX 3050 Ti)
- **Command**:
  ```bash
  cargo run -p ml --example train_ppo --release -- \
    --features 225 \
    --data-dir data/features_225 \
    --iterations 500
  ```
- **Expected Improvement**: +10-20% risk-adjusted returns

##### Model 4: TFT-INT8 (Temporal Fusion Transformer)
- **Training Time**: TBD (GPU RTX 3050 Ti, quantized to INT8)
- **Command**:
  ```bash
  cargo run -p ml --example train_tft_dbn --release -- \
    --features 225 \
    --data-dir data/features_225 \
    --epochs 50 \
    --quantize int8
  ```
- **Expected Improvement**: +15-25% forecasting accuracy

#### Week 5: Wave Comparison Backtest
1. **Backtest Wave C vs. Wave D**:
   ```bash
   cargo run --release --example wave_comparison \
     --symbols ES.FUT,NQ.FUT,6E.FUT,ZN.FUT \
     --start 2024-06-01 --end 2024-12-01
   ```
2. **Expected Results**:
   - **Wave C (201 features)**: Sharpe 1.2, Win Rate 52%, Max DD 15%
   - **Wave D (225 features)**: Sharpe 1.5-1.8, Win Rate 55-60%, Max DD 10-12%
   - **Improvement**: +25-50% Sharpe, +3-8% win rate, -20-33% max drawdown

#### Week 6: Production Validation
1. **Staging Deployment**: Deploy to staging environment
2. **Paper Trading**: 1-2 weeks validation with real market data
3. **Metric Tracking**: Regime transitions, position sizing, stop-loss adjustments
4. **Threshold Tuning**: Adjust CUSUM, ADX, stability window based on real data

### GPU Benchmark Decision

**Option 1: Local Training (RTX 3050 Ti)**
- **Pros**: Zero cost, immediate availability, proven performance
- **Cons**: Limited to 4GB VRAM, slower for large models
- **Cost**: $0
- **Training Time**: 1.86 min (MAMBA-2), 15s (DQN), 7s (PPO)

**Option 2: Cloud Training (AWS EC2 p3.2xlarge with V100)**
- **Pros**: 10-100x faster, 16GB VRAM, scalable
- **Cons**: $3.06/hour, setup overhead, data transfer costs
- **Cost**: ~$50-$100 for full retraining (16-32 hours)
- **Training Time**: 10-20s (MAMBA-2), <1s (DQN/PPO)

**Recommendation**: Start with **local training** (RTX 3050 Ti) for initial validation. Consider cloud if training time exceeds 2-3 hours or VRAM becomes a bottleneck.
