jgrusewski 7458f1be01 feat(wave12): E2E validation complete - 225-feature pipeline ready
 Validation Results:
- PPO training: 24.2s (1 epoch, 950 samples, dim=225)
- Feature extraction: 105μs/bar (9.5x faster than target)
- Model checkpoint: 293KB (147KB actor + 146KB critic)
- GPU memory: 145MB used (96.4% headroom)
- Zero dimension mismatches

📊 Success Criteria (5/5):
 Feature dimension = 225 (Wave C 201 + Wave D 24)
 Model state_dim = 225
 Training completed without errors
 Checkpoint saved successfully
 No dimension mismatch errors

📁 Training Data Ready:
- ES.FUT: 2.9MB, 180 days
- NQ.FUT: 4.4MB, 180 days
- 6E.FUT: 2.8MB, 180 days
- ZN.FUT: 65KB, 90 days (clean)

🚀 Next: Full production model retraining (4 models, ~10min GPU time)

OOM Killed (Exit Code 137)

Symptom: Container exits with code 137

Diagnosis:

# Check pod events
kubectl describe pod foxhunt-trading-service-xxxxx -n foxhunt | grep -A 10 Events

# Output:
# Reason: OOMKilled
# Message: Container exceeded memory limit

# Check memory limits
kubectl get pod foxhunt-trading-service-xxxxx -n foxhunt -o jsonpath='{.spec.containers[0].resources.limits.memory}'

Resolution:

# Increase memory limit
kubectl patch deployment foxhunt-trading-service -n foxhunt \
    -p '{"spec":{"template":{"spec":{"containers":[{"name":"trading-service","resources":{"limits":{"memory":"4Gi"}}}]}}}}'

# OR enable swap (not recommended for production)

Panic/Segfault

Symptom: Container crashes with panic or segfault

Diagnosis:

# Check logs before crash
kubectl logs -n foxhunt foxhunt-trading-service-xxxxx --previous | tail -100

# Output:
# thread 'main' panicked at 'index out of bounds: the len is 10 but the index is 10', src/main.rs:42

Resolution:

# Fix code bug and deploy new version
# Add bounds checking in code
