## Deliverable 2: WAVE_D_OPERATIONAL_RUNBOOK.md

**File**: `/home/jgrusewski/Work/foxhunt/WAVE_D_OPERATIONAL_RUNBOOK.md`
**Size**: 1002 lines
**Purpose**: Incident response guide for Wave D operations

### Contents

#### Common Issues & Resolutions (7 Issues)

**Issue 1: CUSUM False Positives**
- **Symptom**: >100 structural breaks per hour
- **Root Cause**: CUSUM threshold too low for market volatility
- **Resolution**: Increase threshold from 4.0 to 5.0 (10 minutes)
- **Verification**: Break count drops to <10 per hour

**Issue 2: ADX Initialization Failures**
- **Symptom**: ADX stuck at 0.0 despite >10 minutes of data
- **Root Cause**: Insufficient historical data (<28 bars)
- **Resolution**: Wait for 28-bar warmup or restart service (20 minutes)
- **Workaround**: Disable ADX features temporarily

**Issue 3: Transition Matrix Entropy Too High**
- **Symptom**: Shannon entropy >2.5 (random regime switches)
- **Root Cause**: EMA alpha too high (over-reactive)
- **Resolution**: Decrease alpha from 0.1 to 0.05 (10 minutes)
- **Verification**: Entropy drops to <1.5 within 1 hour

**Issue 4: Adaptive Position Sizing Too Aggressive**
- **Symptom**: Position multiplier >2.0x (expected max 1.5x)
- **Root Cause**: Trending regime multiplier misconfigured
- **Resolution**: Reduce multiplier from 1.5x to 1.3x (5 minutes)
- **Emergency Action**: Reduce all positions by 33%

**Issue 5: Stop-Loss Multiplier Out of Range**
- **Symptom**: Stop-loss multiplier >5.0x ATR (expected max 4.0x)
- **Root Cause**: ATR calculation error or multiplier config issue
- **Resolution**: Fix multiplier configuration (5 minutes)
- **Emergency Action**: Manually set stops to 2.0x ATR

**Issue 6: Feature NaN/Inf Detected**
- **Symptom**: ML models fail, training loss NaN
- **Root Cause**: Division by zero in feature calculations
- **Resolution Patches**:
  - Feature 223 (Regime Sharpe): Add std=0 check (10 minutes)
  - Feature 224 (Risk Budget): Add denominator=0 check (10 minutes)
  - Feature 218 (Shannon Entropy): Filter zero probabilities (10 minutes)
- **Deployment**: Rebuild + deploy (15 minutes)

**Issue 7: Regime Flip-Flopping**
- **Symptom**: >50 regime transitions per hour
- **Root Cause**: Stability filter misconfiguration
- **Resolution**: Increase stability window from 5 to 10 bars (10 minutes)
- **Alternative**: Reduce CUSUM weight from 0.40 to 0.25 (15 minutes)

#### Monitoring & Alerting
