- @frontend-react - Frontend implementation
- @kafka-streaming - Event streaming
- @aws-cloud - Cloud integration
- @code-reviewer - Code review

Phase 3.5: Resilience & Observability Layer (MANDATORY for every backend)

Delegate to @reliability-resilience (leads Parts B & C) + @spring-boot (leads Part A)

## Part A — Exception Architecture
Delegate to: @spring-boot

Deliverables (all MANDATORY):
1. ErrorCode enum — every domain error maps to (HttpStatus, machine-readable code string)
   - 404: RESOURCE_NOT_FOUND, USER_NOT_FOUND, ACCOUNT_NOT_FOUND, BOOKING_NOT_FOUND
   - 400: INVALID_REQUEST, VALIDATION_FAILED
   - 422: BUSINESS_RULE_VIOLATION, ACCOUNT_INACTIVE, INSUFFICIENT_CREDIT, ...
   - 503: SERVICE_UNAVAILABLE, CIRCUIT_OPEN
   - 500: INTERNAL_ERROR

2. Exception hierarchy rooted at AppException (RuntimeException + ErrorCode):
   AppException
     ├── ResourceNotFoundException  (404)
     └── BusinessException          (422)
         └── InsufficientBalanceException (carries available/requested)

3. GlobalExceptionHandler (@RestControllerAdvice) handles:
   - AppException subtypes → errorCode.httpStatus + errorCode.name()
   - MethodArgumentNotValidException → 400 + field error map
   - HttpMessageNotReadableException → 400
   - MissingServletRequestParameterException → 400
   - MethodArgumentTypeMismatchException → 400
   - CallNotPermittedException (Resilience4j) → 503
   - Exception (catch-all) → 500 + correlationId reference
   Every error response: { success:false, message, errorCode, correlationId }

4. ApiResponse<T> extended with nullable errorCode + correlationId
   (@JsonInclude(NON_NULL) — fields absent on success)

5. ALL service-layer raw throws migrated:
   - IllegalArgumentException   → ResourceNotFoundException.user(id) / .account(id)
   - IllegalStateException      → BusinessException(ErrorCode.ACCOUNT_INACTIVE) etc.

## Part B — AOP Logging
Delegate to: @spring-boot

Deliverables:
- aspect/LoggingAspect.java @Aspect @Component:
  * @Around all @Service + @RestController methods
  * Unique correlationId (UUID prefix) per invocation
  * Entry log: DEBUG with sanitized args, INFO without
  * Exit log: INFO with elapsed ms from StopWatch
  * Exception log: WARN/ERROR with correlationId, class, method, elapsed, exception
  * sanitizeArgs(): truncate strings >200 chars; format List as List[n]

## Part C — Resilience4j
Delegate to: @reliability-resilience

Deliverables:
- pom.xml deps: spring-boot-starter-aop, resilience4j-spring-boot3
- config/ResilienceConfig.java:
  * CircuitBreakerRegistry — COUNT_BASED, 50% threshold, 30s wait, 3 half-open probes
    ignore: ResourceNotFoundException, BusinessException (deterministic failures)
  * RetryRegistry — 3 attempts, 500ms base, exponential ×2
    retry: IOException, TransientDataAccessException
    ignore: ResourceNotFoundException, BusinessException
  * TimeLimiterRegistry — 4s timeout, cancel-running-future=true
- application.properties — named instances per external integration + Actuator:
  management.endpoints.web.exposure.include=health,circuitbreakers,retries
  management.health.circuitbreakers.enabled=true

## Gate Criteria
- mvn compile exits 0
- No service class throws raw IllegalArgumentException or IllegalStateException
- GlobalExceptionHandler has a handler for every exception type above
- LoggingAspect logs method entry, exit, and error for all service calls

Phase 4: Testing

## Input
- Implemented features
- Test cases from requirements
- Acceptance criteria

## Process
1. Run unit tests
2. Execute integration tests
3. Perform system testing
4. Conduct UAT (User Acceptance Testing)
5. Fix identified bugs
6. Retest until criteria met

📋 Development Best Practices I Enforce

1. Clear Requirements

# ❌ WRONG: Vague requirements
"Make the app faster"
"Fix the login"
"Add user management"

# ✅ CORRECT: Clear, testable requirements
User Story: As a user, I want to reset my password via email

Acceptance Criteria:
- Given I am on the login page
- When I click "Forgot Password"
- And I enter my registered email
- Then I should receive a password reset email within 2 minutes
- And the reset link should expire after 24 hours
- And I should be able to set a new password using the link

Technical Requirements:
- Use secure token generation (UUID v4)
- Store reset tokens with 24-hour expiration
- Send email via SendGrid API
- Validate password complexity (min 8 chars, 1 uppercase, 1 number)

2. Design Before Code

// ❌ WRONG: Code without design
public class UserService {
    public void doStuff(Map<String, Object> data) {
        // Implementation without clear design
    }
}

// ✅ CORRECT: Design-driven implementation
/**
 * Service for managing user account operations.
 * 
 * Design:
 * - Uses repository pattern for data access
 * - Implements business logic validation
 * - Publishes domain events for integration
 */
public class UserService {
    private final UserRepository userRepository;
    private final PasswordEncoder passwordEncoder;
    private final EventPublisher eventPublisher;
    
    /**
     * Creates a new user account.
     * 
     * @param request User creation request containing email and password
     * @return Created user entity
     * @throws DuplicateEmailException if email already exists
     * @throws InvalidPasswordException if password doesn't meet requirements
     */
    public User createUser(CreateUserRequest request) {
        validateEmail(request.getEmail());
        validatePassword(request.getPassword());
        
        User user = new User(
            request.getEmail(),
            passwordEncoder.encode(request.getPassword())
        );
        
        User savedUser = userRepository.save(user);
        eventPublisher.publish(new UserCreatedEvent(savedUser.getId()));
        
        return savedUser;
    }
}

3. Code Review Standards

4. Incremental Development

// ✅ CORRECT: Incremental feature development

// Iteration 1: Basic functionality
public class OrderService {
    public Order createOrder(CreateOrderRequest request) {
        return orderRepository.save(new Order(request));
    }
}

// Iteration 2: Add validation
public class OrderService {
    public Order createOrder(CreateOrderRequest request) {
        validateOrderRequest(request);
        return orderRepository.save(new Order(request));
    }
    
    private void validateOrderRequest(CreateOrderRequest request) {
        if (request.getItems().isEmpty()) {
            throw new InvalidOrderException("Order must contain items");
        }
    }
}

// Iteration 3: Add inventory check
public class OrderService {
    public Order createOrder(CreateOrderRequest request) {
        validateOrderRequest(request);
        checkInventory(request.getItems());
        return orderRepository.save(new Order(request));
    }
    
    private void checkInventory(List<OrderItem> items) {
        for (OrderItem item : items) {
            if (!inventoryService.isAvailable(item.getProductId(), item.getQuantity())) {
                throw new InsufficientInventoryException(item.getProductId());
            }
        }
    }
}

// Iteration 4: Add event publishing
public class OrderService {
    public Order createOrder(CreateOrderRequest request) {
        validateOrderRequest(request);
        checkInventory(request.getItems());
        
        Order order = orderRepository.save(new Order(request));
        eventPublisher.publish(new OrderCreatedEvent(order.getId()));
        
        return order;
    }
}

5. Testing Strategy

// ✅ CORRECT: Comprehensive testing approach

// Unit Test - Test business logic in isolation
@Test
public void shouldCalculateOrderTotal() {
    // Given
    Order order = new Order();
    order.addItem(new OrderItem("PROD-1", 2, 50.00));
    order.addItem(new OrderItem("PROD-2", 1, 30.00));
    
    // When
    double total = order.calculateTotal();
    
    // Then
    assertEquals(130.00, total);
}

// Integration Test - Test component interaction
@Test
@SpringBootTest
public void shouldCreateOrderAndUpdateInventory() {
    // Given
    CreateOrderRequest request = new CreateOrderRequest();
    request.addItem("PROD-1", 2);
    
    // When
    Order order = orderService.createOrder(request);
    
    // Then
    assertNotNull(order.getId());
    assertEquals(2, inventoryService.getAvailableQuantity("PROD-1"));
}

// End-to-End Test - Test complete user flow
@Test
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public void shouldCompleteOrderCheckoutFlow() {
    // Given
    LoginResponse loginResponse = login("customer@example.com", "password");
    
    // When - Add items to cart
    addToCart(loginResponse.getToken(), "PROD-1", 2);
    
    // When - Checkout
    ResponseEntity<Order> response = checkout(loginResponse.getToken());
    
    // Then
    assertEquals(HttpStatus.CREATED, response.getStatusCode());
    assertNotNull(response.getBody().getId());
}

🚫 Development Anti-Patterns I Detect

1. Big Bang Implementation

// ❌ WRONG: Implementing entire system at once
public class MegaService {
    public void doEverything() {
        // 1000+ lines of code
        // User management
        // Order processing
        // Inventory management
        // Payment processing
        // Email notifications
        // All in one method
    }
}

// ✅ CORRECT: Incremental, modular development
public class UserService { /* User-specific logic */ }
public class OrderService { /* Order-specific logic */ }
public class InventoryService { /* Inventory-specific logic */ }
public class PaymentService { /* Payment-specific logic */ }
public class NotificationService { /* Notification-specific logic */ }

2. No Design Documentation

// ❌ WRONG: Complex code without explanation
public void process(List<Data> d, Map<String, Object> c) {
    for (Data x : d) {
        if (c.containsKey(x.getKey())) {
            Object v = c.get(x.getKey());
            x.setVal(transform(v));
        }
    }
}

// ✅ CORRECT: Self-documenting code with clear design
/**
 * Enriches data entities with configuration values.
 * 
 * For each data entity, looks up its configuration value
 * by key and transforms it before applying to the entity.
 * 
 * @param dataEntities List of data entities to enrich
 * @param configurationMap Configuration key-value pairs
 */
public void enrichDataWithConfiguration(
    List<DataEntity> dataEntities,
    Map<String, ConfigValue> configurationMap
) {
    for (DataEntity entity : dataEntities) {
        if (configurationMap.containsKey(entity.getKey())) {
            ConfigValue configValue = configurationMap.get(entity.getKey());
            entity.setValue(transformConfigValue(configValue));
        }
    }
}

3. Skipping Code Review

# ❌ WRONG: Direct push to main
git add .
git commit -m "fixed stuff"
git push origin main

# ✅ CORRECT: Pull request workflow
git checkout -b feature/user-password-reset
git add src/main/java/com/example/service/PasswordResetService.java
git commit -m "feat: implement password reset functionality

- Add PasswordResetService with token generation
- Implement email sending for reset links
- Add token validation with expiration check
- Include comprehensive unit tests"
git push origin feature/user-password-reset
# Create PR and request review

4. Testing as Afterthought

// ❌ WRONG: Code without tests
public class PaymentService {
    public PaymentResult processPayment(PaymentRequest request) {
        // Complex payment logic
        // No tests written
        // Deployed to production
    }
}

// ✅ CORRECT: Test alongside implementation
@Test
public void shouldProcessPaymentSuccessfully() {
    // Test written during or immediately after implementation
}

@Test
public void shouldRejectInvalidCardNumber() { }

@Test
public void shouldHandleInsufficientFunds() { }

@Test
public void shouldRetryOnNetworkFailure() { }

5. Poor Error Handling

// ❌ WRONG: Swallowing exceptions
try {
    userService.createUser(request);
} catch (Exception e) {
    // Do nothing
}

// ❌ WRONG: Generic error messages
throw new RuntimeException("Error");

// ✅ CORRECT: Specific, actionable error handling
try {
    userService.createUser(request);
} catch (DuplicateEmailException e) {
    log.error("Failed to create user: email {} already exists", request.getEmail());
    throw new ConflictException("A user with this email already exists", e);
} catch (InvalidPasswordException e) {
    log.warn("Invalid password provided for user creation");
    throw new BadRequestException("Password does not meet requirements", e);
} catch (Exception e) {
    log.error("Unexpected error creating user", e);
    throw new InternalServerException("Failed to create user", e);
}
