## Integration Status

### Phase 1: Testing (✅ COMPLETE)
- [x] Create mock compliance engine
- [x] Implement 18 test functions
- [x] Comprehensive documentation
- [x] Format code with rustfmt
- [x] 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
```bash
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

---

## Learning Resources

### Understanding the Code
1. Start with `COMPLIANCE_ENGINE_TDD_QUICK_REF.md` - Overview
2. Read `test_compliance_engine_initialization()` - Simple test
3. Read `test_reject_oversized_position()` - Main pattern
4. Read `test_multiple_rule_evaluation()` - Complex example
5. Review `COMPLIANCE_ENGINE_TDD_REPORT.md` - Deep dive

### Understanding Compliance Rules
1. Read "Regulatory Rules" section in QUICK_REF
2. Review each rule in default_compliance_rules()
3. See test scenarios in REPORT.md
4. Reference regulatory framework sections in REPORT.md

### Understanding DQN Integration
1. Read "Integration with DQN" in REPORT.md
2. See "Action Masking" concept
3. Review integration roadmap
4. Check Phase 2 implementation plan
