## Production Deployment Steps

### Step 1: Environment Setup (5 minutes) ⚠️ CRITICAL

#### 1.1 Set JWT Secret
**CRITICAL**: System will fail without this environment variable.

```bash
# Set JWT secret (REQUIRED)
export JWT_SECRET="OvFLDUbIDak3CSCi5t6zKfsAp65cjTOJ85q9YE+TFY8b361DGg1gSTra2rW6mps3cWrRGQ/NXRA5uftUpMldvOaEHMMgfBs4JjVODDElREdvUFm0EttD1A=="

# Verify it's set
echo $JWT_SECRET | wc -c  # Should output 129 (128 chars + newline)
```

**Why Critical**: Agent 158 identified JWT secret mismatch as causing 100% authentication failures. Fail-fast pattern now enforces this.

#### 1.2 Verify Docker Infrastructure
```bash
# Start all infrastructure
docker-compose up -d

# Wait for health checks (30 seconds)
sleep 30

# Verify all services healthy
docker-compose ps

# Expected output:
# api_gateway        Up (healthy)   50051, 9091
# trading_service    Up (healthy)   50052, 9092
# backtesting_service Up (healthy)  50053, 8083, 9093
# ml_training_service Up (healthy)  50054, 8095, 9094
# postgres           Up (healthy)   5432
# redis              Up (healthy)   6379
# vault              Up (healthy)   8200
```

**Success Criteria**: All 7 services showing "Up (healthy)"

---

### Step 2: Compilation Verification (5 minutes)

#### 2.1 Build Workspace
```bash
# Build all services
cargo build --workspace --all-features

# Expected: No compilation errors
```

**Success Criteria**: Build completes with 0 errors (warnings OK)

#### 2.2 Verify Dependencies
```bash
# Check all agent fixes applied
git diff main --stat

# Expected files modified:
# - Cargo.lock (+3)
# - services/stress_tests/Cargo.toml (+2)
# - tests/e2e/src/framework.rs (+3, -3)
# - tests/e2e/tests/ml_inference_e2e.rs (+2, -2)
# - trading_engine/Cargo.toml (+1)
```

**Success Criteria**: All 5 files show expected changes

---

### Step 3: E2E Test Validation (15 minutes)

#### 3.1 Core Integration Tests
```bash
# Run core E2E tests (MUST set JWT_SECRET first!)
cargo test -p foxhunt_e2e --test integration_test -- --nocapture --test-threads=1

# Expected output:
# running 15 tests
# test result: ok. 15 passed; 0 failed; 0 ignored
```

**Success Criteria**: 15/15 tests passing (validated by Agent 159)

#### 3.2 Comprehensive Trading Workflows
```bash
# Run comprehensive workflows
cargo test -p foxhunt_e2e --test comprehensive_trading_workflows -- --nocapture --test-threads=1

# Expected: All workflow tests pass
```

**Success Criteria**: No test failures

#### 3.3 Config Hot-Reload Tests (Serial Execution Required)
```bash
# Config tests MUST run serially (Agent 158 finding)
cargo test --test config_hot_reload -- --test-threads=1

# Expected: Config tests pass when run serially
```

**Success Criteria**: Config tests complete without race conditions

---

### Step 4: Service Health Validation (5 minutes)

#### 4.1 gRPC Health Checks
```bash
# Check all gRPC services responding
grpc_health_probe -addr=localhost:50051  # API Gateway
grpc_health_probe -addr=localhost:50052  # Trading Service
grpc_health_probe -addr=localhost:50053  # Backtesting Service
grpc_health_probe -addr=localhost:50054  # ML Training Service

# Expected: All return "SERVING"
```

**Success Criteria**: All 4 services respond "SERVING"

#### 4.2 HTTP Health Endpoints
```bash
# Check HTTP health endpoints
curl http://localhost:8080/health  # API Gateway
curl http://localhost:8081/health  # Trading Service
curl http://localhost:8082/health  # Backtesting Service
curl http://localhost:8095/health  # ML Training Service

# Expected: All return 200 OK
```

**Success Criteria**: All 4 endpoints return HTTP 200

#### 4.3 Database Connectivity
```bash
# PostgreSQL
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "SELECT 1;"

# Redis
redis-cli -h localhost -p 6379 ping

# Expected:
# PostgreSQL: Returns "1"
# Redis: Returns "PONG"
```

**Success Criteria**: Both databases respond correctly

---

### Step 5: Performance Smoke Tests (10 minutes)

#### 5.1 Database Throughput Validation
```bash
# Run Agent 156 validated performance test
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt < test_pg_performance.sql

# Expected: ~2,979 inserts/sec (validated by Agent 156)
```

**Success Criteria**: Throughput ≥2,500 inserts/sec (within 20% of validated)

#### 5.2 API Gateway Latency
```bash
# Quick latency test (requires JWT token)
# TODO: Add specific command for API Gateway latency test
```

**Success Criteria**: P99 latency <1ms (validated 21-488μs by Agent 248)

---

### Step 6: Monitoring Setup (5 minutes)

#### 6.1 Prometheus Targets
```bash
# Check Prometheus targets
curl http://localhost:9090/api/v1/targets | jq '.data.activeTargets[] | select(.health != "up")'

# Expected: Empty output (all targets up)
```

**Success Criteria**: All Prometheus targets showing "up"

#### 6.2 Grafana Dashboards
```bash
# Access Grafana
open http://localhost:3000
# Login: admin / foxhunt123

# Verify dashboards operational:
# - Trading System Overview
# - Database Performance
# - API Gateway Metrics
# - ML Pipeline Status
```

**Success Criteria**: All dashboards loading with live data

---

## Post-Deployment Validation (30 minutes)

### Validate Critical Paths

#### 6.3 Submit Test Order
```bash
# Test order submission via API Gateway
# TODO: Add specific gRPC call with JWT auth
```

**Success Criteria**: Order submission successful, <100ms latency

#### 6.4 Query Position
```bash
# Test position query
# TODO: Add specific gRPC call
```

**Success Criteria**: Position query successful

#### 6.5 ML Inference Test
```bash
# Test ML model inference
# TODO: Add specific test
```

**Success Criteria**: Inference completes <100ms (single model)

---

## Rollback Plan

### If Deployment Fails

#### Immediate Rollback Steps
```bash
# 1. Stop all services
docker-compose down

# 2. Restore previous version
git checkout <previous-commit>

# 3. Rebuild
cargo build --workspace

# 4. Restart services
docker-compose up -d
```

#### Rollback Success Criteria
- All services return to healthy state
- Previous E2E tests pass
- No data corruption in PostgreSQL

---

## Known Issues (Non-Blocking)

### Medium Priority (1-2 weeks post-deployment)
- **AuditTrailEngine async context** (2 tests, 30 min fix)
- **PostgreSQL NOTIFY race** (1 test, 15 min fix)
- **Error message formats** (2 tests, 10 min fix)

### Low Priority (1-3 months)
- **Percentile calculation** (1 test, 5 min fix)
- **TSC timing** (1 test, hardware limitation)
- **ML model loading** (1 test, service lifecycle)
- **Market data streaming** (3 tests, future wave)
- **Emergency shutdown API Gateway** (3 tests, 4-8 hours)

**Impact**: None of these issues block production deployment.

### Troubleshooting Guide

#### JWT Authentication Failures
**Symptom**: 401 Unauthorized errors
**Cause**: JWT_SECRET not set or incorrect
**Fix**:
```bash
export JWT_SECRET="OvFLDUbIDak3CSCi5t6zKfsAp65cjTOJ85q9YE+TFY8b361DGg1gSTra2rW6mps3cWrRGQ/NXRA5uftUpMldvOaEHMMgfBs4JjVODDElREdvUFm0EttD1A=="
```

#### Service Health Check Failures
**Symptom**: docker-compose ps shows "unhealthy"
**Cause**: Service startup issue or port conflict
**Fix**:
```bash
# Check logs
docker-compose logs <service-name>

# Check port availability
lsof -i :PORT

# Restart service
docker-compose restart <service-name>
```

#### Compilation Errors
**Symptom**: cargo build fails
**Cause**: Missing Agent 158 fixes
**Fix**:
```bash
# Verify all fixes applied
git diff main services/stress_tests/Cargo.toml
git diff main trading_engine/Cargo.toml
git diff main tests/e2e/src/framework.rs

# If missing, apply fixes:
git cherry-pick <wave-137-commit>
```
