---

Integration Status

Phase 1: Testing (✅ COMPLETE)

• Create mock compliance engine
• Implement 18 test functions
• Comprehensive documentation
• Format code with rustfmt
• Ready for deployment

Phase 2: DQN Integration (NEXT)

• Integrate with risk/src/compliance.rs ComplianceValidator
• Add compliance checking to DQN action selection
• Implement action masking in training loop
• Add compliance metrics to logs

Phase 3: Production (FUTURE)

• Rule configuration per account
• Compliance violation alerting
• Audit trail export/reporting
• Hot-reload capability

---

Reference Quick Links

Configuration

• Default rules defined in create_default_compliance_rules()
• 6 rules with IDs, categories, severity levels
• Easy to extend with new rules

Mock API

• MockComplianceEngine::new(rules) - Initialize
• engine.check_action(symbol, action, position_size, timestamp, override) - Check compliance
• engine.check_action_with_portfolio(...) - Check with portfolio context
• Methods for adding restrictions, tracking trades, triggering halts

Test Patterns

• Positive Case: assert!(result.is_compliant)
• Negative Case: assert!(!result.is_compliant)
• Violation Check: assert_eq!(result.violations[0].rule_id, "RULE_ID")
• Override: Some("EMERGENCY_OVERRIDE")

Common Tasks

Find Tests for Rule X

grep -n "test_.*position" ml/tests/compliance_engine_dqn_integration_test.rs
grep -n "test_.*trading" ml/tests/compliance_engine_dqn_integration_test.rs
grep -n "test_.*concentration" ml/tests/compliance_engine_dqn_integration_test.rs

See All Mock Types

Read lines 620-700 in compliance_engine_dqn_integration_test.rs

• MockAction
• MockComplianceRule
• MockComplianceViolation
• MockComplianceResult
• MockComplianceEngine

Read Default Rules

Read create_default_compliance_rules() function (lines 860-920)

Understand Test Pattern

See test_reject_oversized_position() (lines 60-90) Shows: Arrange, Act, Assert

---

Troubleshooting

Tests Won't Compile

• Ensure you're in the foxhunt root directory
• Run: cargo test -p ml --test compliance_engine_dqn_integration_test --release

Test Fails

• Check assertion message for details
• Refer to COMPLIANCE_ENGINE_TDD_QUICK_REF.md troubleshooting section
• Verify mock engine state matches test expectations

Need to Add New Test

1. Follow AAA pattern (Arrange-Act-Assert)
2. Use descriptive test name
3. Add Test Case, Expected, Severity comments
4. Add custom assertion messages
5. Group with related tests
