## Test Execution Guide

### Quick Validation (Core Tests)

```bash
# Run core endpoint tests (no services required)
./scripts/validate_grpc_endpoints.sh

# Expected output:
# Total Tests:  6
# Passed:       6
# Failed:       0
# Pass Rate:    100%
# ✅ ALL TESTS PASSED
```

### Full Integration Testing (Requires Services)

```bash
# Step 1: Start infrastructure
docker-compose up -d postgres redis vault

# Step 2: Start Trading Service
cargo run -p trading_service --release &
TRADING_PID=$!
sleep 8

# Step 3: Run regime detection tests
cargo test -p trading_service --test regime_grpc_integration_test -- --ignored --nocapture

# Step 4: Cleanup
kill $TRADING_PID
```

### Manual gRPC Testing (grpcurl)

```bash
# Install grpcurl (if needed)
go install github.com/fullstorydev/grpcurl/cmd/grpcurl@latest

# Test GetRegimeState
grpcurl -plaintext \
  -d '{"symbol":"ES.FUT"}' \
  localhost:50052 \
  foxhunt.trading.TradingService/GetRegimeState

# Test GetRegimeTransitions
grpcurl -plaintext \
  -d '{"symbol":"ES.FUT","limit":10}' \
  localhost:50052 \
  foxhunt.trading.TradingService/GetRegimeTransitions

# Test via API Gateway (port 50051)
grpcurl -plaintext \
  -d '{"symbol":"NQ.FUT"}' \
  localhost:50051 \
  foxhunt.trading.TradingService/GetRegimeState
```

### TLI Command Testing

```bash
# Authenticate
tli auth login

# Test regime detection commands
tli trade ml regime --symbol ES.FUT
tli trade ml transitions --symbol ES.FUT --limit 20
tli trade ml adaptive-metrics --symbol ES.FUT
```

## 225-Feature Extraction Architecture

### Feature Pipeline Flow

```
Market Data → Feature Extractor → 225-Feature Vector → ML Models
    ↓              ↓                       ↓                ↓
  DBN Bar    Wave C (201)          Regime Features    DQN/PPO/MAMBA/TFT
             Wave D (24)           (indices 201-224)
```

### Feature Breakdown

| Feature Set | Indices | Count | Description |
|-------------|---------|-------|-------------|
| **Base OHLCV** | 0-17 | 18 | Open, High, Low, Close, Volume, Returns |
| **Wave A Indicators** | 18-25 | 8 | RSI, MACD, Bollinger, ATR |
| **Microstructure** | 26-67 | 42 | Order flow, spreads, imbalances |
| **Alternative Bars** | 68-95 | 28 | Tick, volume, dollar, imbalance bars |
| **Wave C Advanced** | 96-200 | 105 | Statistical, fractal, regime features |
| **Wave D CUSUM** | 201-210 | 10 | Structural break detection |
| **Wave D ADX** | 211-215 | 5 | Directional indicators |
| **Wave D Transitions** | 216-220 | 5 | Regime transition probabilities |
| **Wave D Adaptive** | 221-224 | 4 | Adaptive strategy metrics |
| **TOTAL** | 0-224 | **225** | Complete feature set |

### Integration Points

1. **Common Crate** (`ProductionFeatureExtractor225` trait)
   - Interface for 225-feature extraction
   - Used by all services via `SharedMLStrategy`

2. **ML Crate** (`FeatureExtractor::extract_current_features()`)
   - Production implementation
   - Returns `Tensor<[225]>`

3. **Trading Service** (Real-time extraction)
   - Extracts features for each incoming order
   - Uses regime state for adaptive sizing

4. **Backtesting Service** (Historical replay)
   - Extracts features from DBN data
   - Validates strategy performance
