# Production Deployment Checklist - Foxhunt HFT System
|
|
|
|
## 📋 CRITICAL PRE-DEPLOYMENT VALIDATION
|
|
|
|
**Status**: ⚠️ **REQUIRES FIXES BEFORE DEPLOYMENT** ⚠️
|
|
|
|
Based on comprehensive expert analysis, **3 CRITICAL and 4 HIGH severity issues** must be resolved before production deployment.
|
|
|
|
## 🔴 CRITICAL ISSUES (MUST FIX)
|
|
|
|
### 1. Silent Health Monitoring System
|
|
**File**: `ml/src/observability/metrics.rs:416-434`
|
|
**Impact**: Production monitoring will always report "healthy" hiding system degradation
|
|
**Issue**: All metrics calculation functions return hardcoded values (0, 1.0)
|
|
```rust
|
|
// BROKEN - Always returns 0
|
|
fn calculate_total_predictions(&self) -> u64 { 0 }
|
|
fn calculate_average_latency(&self) -> f64 { 0.0 }
|
|
fn calculate_error_rate(&self) -> f64 { 0.0 }
|
|
fn calculate_health_score(&self) -> f64 { 1.0 }
|
|
```
|
|
**Fix Required**:
|
|
```rust
|
|
fn calculate_total_predictions(&self) -> u64 {
|
|
self.predictions_total.collect().map(|m| m.get()).unwrap_or(0)
|
|
}
|
|
```
|
|
|
|
### 2. High-Frequency Logging Performance Issue
|
|
**File**: `risk/src/position_tracker.rs:475-480`
|
|
**Impact**: INFO logging in hot path will cause millions of log entries per second
|
|
**Issue**: Every position update emits INFO log - will crash production with I/O backpressure
|
|
**Fix Required**: Change to `debug!` or implement sampling
|
|
|
|
### 3. O(n) Position Scanning Performance
|
|
**File**: `risk/src/position_tracker.rs:575-621`
|
|
**Impact**: CPU-bound risk engine under 100k ticks/second load
|
|
**Issue**: Every market data update scans ALL positions instead of relevant ones
|
|
**Fix Required**: Implement secondary index `InstrumentId -> Vec<PositionKey>`
|
|
|
|
## 🟡 HIGH PRIORITY ISSUES (SHOULD FIX)
|
|
|
|
### 4. Metrics Initialization Race Condition
|
|
**File**: `ml/src/observability/metrics.rs:478-488`
|
|
**Issue**: Multiple initialization calls will panic at runtime
|
|
**Fix**: Add initialization guard
|
|
|
|
### 5. Secret Generation Security Risk
|
|
**File**: `scripts/generate-production-secrets.sh`
|
|
**Issue**: Generates plaintext secrets in world-readable `/tmp`
|
|
**Fix**: Require explicit secure path or auto-delete
|
|
|
|
### 6. Complex Fallback Code Maintenance
|
|
**File**: `risk/src/position_tracker.rs:35-171`
|
|
**Issue**: 500 lines of duplicated fallback code
|
|
**Fix**: Extract reusable helper functions
|
|
|
|

## 🚨 MANDATORY FIXES BEFORE DEPLOYMENT
|
|
|
|
1. **Implement Real Metrics Collection** (Critical)
|
|
- Fix all `calculate_*` functions in ML metrics
|
|
- Ensure health checks can detect actual problems
|
|
|
|
2. **Fix Performance Hot Paths** (Critical)
|
|
- Remove/limit INFO logging in position updates
|
|
- Implement position indexing or document performance caveat
|
|
|
|
3. **Secure Secret Management** (High)
|
|
- Fix secret generation script security
|
|
- Add initialization guards
|
|
|
|
## 📊 VALIDATION COMMANDS
|
|
|
|
```bash
|
|
# Verify compilation
|
|
cargo check --workspace --all-targets
|
|
|
|
# Test individual modules
|
|
cargo check -p ml
|
|
cargo check -p risk
|
|
cargo check -p foxhunt-core
|
|
|
|
# Run tests
|
|
cargo test --workspace
|
|
|
|
# Build for production
|

cargo build --release
|
|
```
|
|
|
|
## 🔄 DEPLOYMENT PROCESS
|
|
|
|
