Rollback Procedures

Level 1: Feature-Only Rollback (Low Risk)

Scenario: Wave D features causing issues, but services stable.

Steps:

1. Disable Wave D features in config:

   // Revert to Wave C (201 features)
   pub const FEATURE_CONFIG: FeatureConfig = FeatureConfig::new_wave_c();
   

2. Restart services:

   systemctl restart ml_training_service
   systemctl restart backtesting_service
   systemctl restart trading_agent_service
   

3. Verify:

   cargo test -p ml --lib features::config
   # Expected: Wave C config tests passing
   

Downtime: <5 minutes Data Loss: None (regime data retained)

Level 2: Database Rollback (Medium Risk)

Scenario: Database schema changes causing issues.

Steps:

1. Stop all services:

   systemctl stop trading_agent_service
   systemctl stop trading_service
   systemctl stop backtesting_service
   systemctl stop ml_training_service
   

2. Rollback migration 045:

   cargo sqlx migrate revert
   
   # Or manual rollback:
   psql -U foxhunt -d foxhunt < migrations/rollback/045_wave_d_regime_tracking_rollback.sql
   

3. Verify schema:

   SELECT column_name FROM information_schema.columns
   WHERE table_name = 'trades';
   
   -- Verify regime columns removed
   

4. Restart services:

   systemctl start ml_training_service
   systemctl start backtesting_service
   systemctl start trading_service
   systemctl start trading_agent_service
   

Downtime: ~15 minutes Data Loss: Regime tracking data (not critical)

Level 3: Full Rollback (High Risk)

Scenario: Wave D deployment causing critical issues.

Steps:

1. Stop all trading:

   tli trade ml stop
   # Verify no open positions
   tli trade positions --status OPEN
   

2. Stop all services:

   systemctl stop trading_agent_service
   systemctl stop trading_service
   systemctl stop backtesting_service
   systemctl stop ml_training_service
   systemctl stop api_gateway
   

3. Restore pre-Wave D binaries:

   cp /opt/foxhunt/bin/backup/pre_wave_d/* /opt/foxhunt/bin/
   

4. Rollback database:

   psql -U foxhunt -d foxhunt < foxhunt_pre_wave_d_backup.sql
   

5. Restart services:

   systemctl start api_gateway
   systemctl start ml_training_service
   systemctl start backtesting_service
   systemctl start trading_service
   systemctl start trading_agent_service
   

6. Verify health:

   grpc_health_probe -addr=localhost:50051
   grpc_health_probe -addr=localhost:50052
   grpc_health_probe -addr=localhost:50053
   grpc_health_probe -addr=localhost:50054
   grpc_health_probe -addr=localhost:50055
   

Downtime: ~30-60 minutes Data Loss: All Wave D data (regime transitions, adaptive params)

---

Troubleshooting

Issue 1: Regime Flip-Flopping (>50 transitions/hour)

Symptoms:

• Prometheus alert: RegimeFlipFloppingDetected
• Grafana: Regime transitions spiking
• Trading: Excessive order placements/cancellations

Root Cause: Stability filter window too small or voting weights imbalanced.

Solution:

// Increase stability window (default: 5 bars)
pub const STABILITY_WINDOW: usize = 10; // Require 60%+ agreement over 10 bars

// Or adjust CUSUM threshold (default: 4.0)
pub const CUSUM_THRESHOLD: f64 = 5.0; // Less sensitive (fewer breaks)

// Or reduce CUSUM weight (default: 40%)
pub const REGIME_CLASSIFIER_WEIGHTS: RegimeWeights = RegimeWeights {
    cusum: 0.25,      // Reduce CUSUM influence
    trending: 0.35,   // Increase trend influence
    ranging: 0.25,
    volatile: 0.15,
};

Verification:

cargo test -p ml --test ensemble_test -- --nocapture
# Expected: Fewer regime transitions in test data

Issue 2: CUSUM False Positive Spike (>100 breaks/hour)

Symptoms:

• Prometheus alert: CUSUMFalsePositiveSpike
• Grafana: cusum_break_count spiking
• Logs: Excessive "Structural break detected" messages

Root Cause: CUSUM threshold too low or drift allowance too small.

Solution:

// Increase CUSUM threshold (default: 4.0)
cusum_threshold: 5.0, // Require larger deviation for break

// Or increase drift allowance (default: 0.5)
cusum_drift_allowance: 0.75, // Allow more drift before detection

Verification:

cargo test -p ml --test cusum_test -- test_false_positive_rate
# Expected: False positive rate <0.5%

Issue 3: ADX Initialization Failure (ADX stuck at 0)

Symptoms:

• Prometheus alert: ADXInitializationFailure
• Grafana: ADX = 0.0 despite 10+ minutes of data
• Logs: "ADX not initialized, returning zeros"

Root Cause: Insufficient bars for ADX calculation (requires 28 bars minimum).

Solution:

// Check ADX initialization status
if !adx_extractor.is_initialized() {
    warn!("ADX not initialized for {}, need {} more bars",
          symbol, 28 - adx_extractor.bar_count());
}

// Or reduce ADX period (default: 14)
adx_period: 10, // Requires 20 bars instead of 28

Verification:

cargo test -p ml --test adx_features_test -- test_initialization
# Expected: ADX initializes after 28 bars

Issue 4: Feature NaN/Inf Values

Symptoms:

• Prometheus alert: FeatureDataQualityIssue
• Grafana: wave_d_feature_nan_count or wave_d_feature_inf_count >0
• ML models: Training loss NaN or Inf

Root Cause: Division by zero or numerical instability in feature calculations.

Solution:

// Check for common causes:

// 1. Sharpe ratio: zero volatility
let std = variance.sqrt();
if std > 1e-10 {
    (mean / std) * (252.0_f64).sqrt()
} else {
    0.0 // Return 0.0 instead of NaN
}

// 2. Risk budget: zero max position
if self.max_position_size > 1e-10 {
    (self.current_position_size / (position_mult * self.max_position_size))
        .clamp(0.0, 1.0)
} else {
    0.0
}

// 3. Transition entropy: zero probabilities
.filter(|&p| p > 1e-10) // Filter before log
.map(|p| -p * p.log2())

Verification:

cargo test -p ml --test regime_adaptive_test -- test_all_features_finite
# Expected: All features finite for all regimes

Issue 5: High Feature Extraction Latency (P99 >100μs)

Symptoms:

• Prometheus alert: FeatureExtractionLatencyHigh
• Grafana: P99 latency >100μs
• Trading: Orders delayed

Root Cause: Inefficient feature calculation or excessive allocations.

Solution:

// Profile feature extraction
cargo flamegraph -p ml --test feature_extraction_bench

// Common optimizations:
// 1. Pre-allocate buffers
let mut bars_buffer = VecDeque::with_capacity(100);

// 2. Inline ATR calculation (avoid function call overhead)
let atr = if bars.len() >= self.atr_period {
    // Inline calculation
} else {
    0.0
};

// 3. Cache intermediate results
if self.cached_adx.is_none() {
    self.cached_adx = Some(self.compute_adx());
}

Verification:

cargo bench -p ml --bench regime_benchmarks
# Expected: P99 <50μs per feature
