 ## 15. Domain Event Usage Validation
 ### Eric Evans: Domain-Driven Design (2003)
 **Original Definition:**
 - Domain Events: "Something happened that domain experts care about"
 - Events capture facts about the domain that have already occurred
 - Distinct from system events - they model business-relevant occurrences
 - Reference: [Martin Fowler - Domain Event](https://martinfowler.com/eaaDev/DomainEvent.html)
 **Book: Domain-Driven Design** (2003)
 - Author: Eric Evans
 - Publisher: Addison-Wesley Professional
 - ISBN: 978-0321125217
 - Domain Events weren't explicitly in the original book but evolved from DDD community
 - Reference: [DDD Community - Domain Events](https://www.domainlanguage.com/)
 ### Vaughn Vernon: Implementing Domain-Driven Design (2013)
 **Chapter 8: Domain Events**
 - Author: Vaughn Vernon
 - Comprehensive coverage of Domain Events implementation
 - "Model information about activity in the domain as a series of discrete events"
 - Reference: [Amazon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
 **Key Principles:**
 - Events should be immutable
 - Named in past tense (OrderPlaced, UserRegistered)
 - Contain all data needed by handlers
 - Enable loose coupling between aggregates
 ### Martin Fowler's Event Patterns
 **Event Sourcing:**
 - "Capture all changes to an application state as a sequence of events"
 - Events become the primary source of truth
 - Reference: [Martin Fowler - Event Sourcing](https://martinfowler.com/eaaDev/EventSourcing.html)
 **Event-Driven Architecture:**
 - Promotes loose coupling between components
 - Enables asynchronous processing
 - Reference: [Martin Fowler - Event-Driven](https://martinfowler.com/articles/201701-event-driven.html)
 ### Why Direct Infrastructure Calls Are Bad
 **Coupling Issues:**
 - Direct calls create tight coupling between domain and infrastructure
 - Makes testing difficult (need to mock infrastructure)
 - Violates Single Responsibility Principle
 - Reference: [Microsoft - Domain Events Design](https://learn.microsoft.com/en-us/dotnet/architecture/microservices/microservice-ddd-cqrs-patterns/domain-events-design-implementation)
 **Benefits of Domain Events:**
 - Decouples domain from side effects
 - Enables eventual consistency
 - Improves testability
 - Supports audit logging naturally
 - Reference: [Jimmy Bogard - Domain Events](https://lostechies.com/jimmybogard/2010/04/08/strengthening-your-domain-domain-events/)

 ## 16. Value Object Immutability
 ### Eric Evans: Domain-Driven Design (2003)
 **Value Object Definition:**
 - "An object that describes some characteristic or attribute but carries no concept of identity"
 - "Value Objects should be immutable"
 - When you care only about the attributes of an element, classify it as a Value Object
 - Reference: [Martin Fowler - Value Object](https://martinfowler.com/bliki/ValueObject.html)
 **Immutability Requirement:**
 - "Treat the Value Object as immutable"
 - "Don't give it any identity and avoid the design complexities necessary to maintain Entities"
 - Reference: [DDD Reference - Value Objects](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
 ### Martin Fowler on Value Objects
 **Blog Post: Value Object** (2016)
 - "A small simple object, like money or a date range, whose equality isn't based on identity"
 - "I consider value objects to be one of the most important building blocks of good domain models"
 - Reference: [Martin Fowler - Value Object](https://martinfowler.com/bliki/ValueObject.html)
 **Key Properties:**
 - Equality based on attribute values, not identity
 - Should be immutable (once created, cannot be changed)
 - Side-effect free behavior
 - Self-validating (validate in constructor)
 ### Vaughn Vernon: Implementing DDD
 **Chapter 6: Value Objects**
 - Detailed implementation guidance
 - "Measures, quantifies, or describes a thing in the domain"
 - "Can be compared with other Value Objects using value equality"
 - "Completely replaceable when the measurement changes"
 - Reference: [Vaughn Vernon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
 ### Why Immutability Matters
 **Thread Safety:**
 - Immutable objects are inherently thread-safe
 - No synchronization needed for concurrent access
 - Reference: [Effective Java - Item 17](https://www.amazon.com/Effective-Java-Joshua-Bloch/dp/0134685997)
 **Reasoning About Code:**
 - Easier to understand code when objects don't change
 - No defensive copying needed
 - Simplifies caching and optimization
 - Reference: [Oracle Java Tutorials - Immutable Objects](https://docs.oracle.com/javase/tutorial/essential/concurrency/immutable.html)
 **Functional Programming Influence:**
 - Immutability is a core principle of functional programming
 - Reduces side effects and makes code more predictable
 - Reference: [Wikipedia - Immutable Object](https://en.wikipedia.org/wiki/Immutable_object)
 ---
 ## 17. Command Query Separation (CQS/CQRS)
 ### Bertrand Meyer: Original CQS Principle
 **Book: Object-Oriented Software Construction** (1988, 2nd Ed. 1997)
 - Author: Bertrand Meyer
 - Publisher: Prentice Hall
 - ISBN: 978-0136291558
 - Introduced Command Query Separation principle
 - Reference: [Wikipedia - CQS](https://en.wikipedia.org/wiki/Command%E2%80%93query_separation)
 **CQS Principle:**
 - "Every method should either be a command that performs an action, or a query that returns data to the caller, but not both"
 - Commands: change state, return nothing (void)
 - Queries: return data, change nothing (side-effect free)
 - Reference: [Martin Fowler - CommandQuerySeparation](https://martinfowler.com/bliki/CommandQuerySeparation.html)
 ### Greg Young: CQRS Pattern
 **CQRS Documents** (2010)
 - Author: Greg Young
 - Extended CQS to architectural pattern
 - "CQRS is simply the creation of two objects where there was previously only one"
 - Reference: [Greg Young - CQRS Documents](https://cqrs.files.wordpress.com/2010/11/cqrs_documents.pdf)
 **Key Concepts:**
 - Separate models for reading and writing
 - Write model (commands) optimized for business logic
 - Read model (queries) optimized for display/reporting
 - Reference: [Microsoft - CQRS Pattern](https://learn.microsoft.com/en-us/azure/architecture/patterns/cqrs)
 ### Martin Fowler on CQRS
 **Blog Post: CQRS** (2011)
 - "At its heart is the notion that you can use a different model to update information than the model you use to read information"
 - Warns against overuse: "CQRS is a significant mental leap for all concerned"
 - Reference: [Martin Fowler - CQRS](https://martinfowler.com/bliki/CQRS.html)
 ### Benefits and Trade-offs
 **Benefits:**
 - Independent scaling of read and write workloads
 - Optimized data schemas for each side
 - Improved security (separate read/write permissions)
 - Reference: [AWS - CQRS Pattern](https://docs.aws.amazon.com/prescriptive-guidance/latest/modernization-data-persistence/cqrs-pattern.html)
 **Trade-offs:**
 - Increased complexity
 - Eventual consistency challenges
 - More code to maintain
 - Reference: [Microsoft - CQRS Considerations](https://learn.microsoft.com/en-us/azure/architecture/patterns/cqrs#issues-and-considerations)

 ## 18. Factory Pattern
 ### Gang of Four: Design Patterns (1994)
 **Book: Design Patterns: Elements of Reusable Object-Oriented Software**
 - Authors: Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides (Gang of Four)
 - Publisher: Addison-Wesley
 - ISBN: 978-0201633610
 - Defines Factory Method and Abstract Factory patterns
 - Reference: [Wikipedia - Design Patterns](https://en.wikipedia.org/wiki/Design_Patterns)
 **Factory Method Pattern:**
 - "Define an interface for creating an object, but let subclasses decide which class to instantiate"
 - Lets a class defer instantiation to subclasses
 - Reference: [Refactoring Guru - Factory Method](https://refactoring.guru/design-patterns/factory-method)
 **Abstract Factory Pattern:**
 - "Provide an interface for creating families of related or dependent objects without specifying their concrete classes"
 - Reference: [Refactoring Guru - Abstract Factory](https://refactoring.guru/design-patterns/abstract-factory)
 ### Eric Evans: Factory in DDD Context
 **Domain-Driven Design** (2003)
 - Chapter 6: "The Life Cycle of a Domain Object"
 - Factories encapsulate complex object creation
 - "Shift the responsibility for creating instances of complex objects and Aggregates to a separate object"
 - Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
 **DDD Factory Guidelines:**
 - Factory should create valid objects (invariants satisfied)
 - Two types: Factory for new objects, Factory for reconstitution
 - Keep creation logic out of the entity itself
 - Reference: Already in Section 10 - Domain-Driven Design
 ### Why Factories Matter in DDD
 **Encapsulation of Creation Logic:**
 - Complex aggregates need coordinated creation
 - Business rules should be enforced at creation time
 - Clients shouldn't know construction details
 - Reference: [Vaughn Vernon - Implementing DDD, Chapter 11](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
 **Factory vs Constructor:**
 - Constructors should be simple (assign values)
 - Factories handle complex creation logic
 - Factories can return different types
 - Reference: [Effective Java - Item 1: Static Factory Methods](https://www.amazon.com/Effective-Java-Joshua-Bloch/dp/0134685997)
 ---
 ## 19. Specification Pattern
 ### Eric Evans & Martin Fowler
 **Original Paper: Specifications** (1997)
 - Authors: Eric Evans and Martin Fowler
 - Introduced the Specification pattern
 - "A Specification states a constraint on the state of another object"
 - Reference: [Martin Fowler - Specification](https://martinfowler.com/apsupp/spec.pdf)
 **Domain-Driven Design** (2003)
 - Chapter 9: "Making Implicit Concepts Explicit"
 - Specifications make business rules explicit and reusable
 - "Create explicit predicate-like Value Objects for specialized purposes"
 - Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
 ### Pattern Definition
 **Core Concept:**
 - Specification is a predicate that determines if an object satisfies some criteria
 - Encapsulates business rules that can be reused and combined
 - Reference: [Wikipedia - Specification Pattern](https://en.wikipedia.org/wiki/Specification_pattern)
 **Three Main Uses:**
 1. **Selection**: Finding objects that match criteria
 2. **Validation**: Checking if object satisfies rules
 3. **Construction**: Describing what needs to be created
 - Reference: [Martin Fowler - Specification](https://martinfowler.com/apsupp/spec.pdf)
 ### Composite Specifications
 **Combining Specifications:**
 - AND: Both specifications must be satisfied
 - OR: Either specification must be satisfied
 - NOT: Specification must not be satisfied
 - Reference: [Refactoring Guru - Specification Pattern](https://refactoring.guru/design-patterns/specification)
 **Benefits:**
 - Reusable business rules
 - Testable in isolation
 - Readable domain language
 - Composable for complex rules
 - Reference: [Enterprise Craftsmanship - Specification Pattern](https://enterprisecraftsmanship.com/posts/specification-pattern-c-implementation/)
 ---
 ## 20. Bounded Context
 ### Eric Evans: Domain-Driven Design (2003)
 **Original Definition:**
 - "A Bounded Context delimits the applicability of a particular model"
 - "Explicitly define the context within which a model applies"
 - Chapter 14: "Maintaining Model Integrity"
 - Reference: [Martin Fowler - Bounded Context](https://martinfowler.com/bliki/BoundedContext.html)
 **Key Principles:**
 - Each Bounded Context has its own Ubiquitous Language
 - Same term can mean different things in different contexts
 - Models should not be shared across context boundaries
 - Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
 ### Vaughn Vernon: Strategic Design
 **Implementing Domain-Driven Design** (2013)
 - Chapter 2: "Domains, Subdomains, and Bounded Contexts"
 - Detailed guidance on identifying and mapping contexts
 - Reference: [Vaughn Vernon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
 **Context Mapping Patterns:**
 - Shared Kernel
 - Customer/Supplier
 - Conformist
 - Anti-Corruption Layer
 - Open Host Service / Published Language
 - Reference: [Context Mapping Patterns](https://www.infoq.com/articles/ddd-contextmapping/)
 ### Why Bounded Contexts Matter
 **Avoiding Big Ball of Mud:**
 - Without explicit boundaries, models become entangled
 - Different teams step on each other's models
 - Reference: [Wikipedia - Big Ball of Mud](https://en.wikipedia.org/wiki/Big_ball_of_mud)
 **Microservices and Bounded Contexts:**
 - "Microservices should be designed around business capabilities, aligned with bounded contexts"
 - Each microservice typically represents one bounded context
 - Reference: [Microsoft - Microservices and Bounded Contexts](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/domain-analysis)
 ### Cross-Context Communication
 **Integration Patterns:**
 - Never share domain models across contexts
 - Use integration events or APIs
 - Translate between context languages
 - Reference: [Microsoft - Tactical DDD](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/tactical-ddd)
 ---
 ## 21. Persistence Ignorance
 ### Definition and Principles
 **Core Concept:**
 - Domain objects should have no knowledge of how they are persisted
 - Business logic remains pure and testable
 - Infrastructure concerns are separated from domain
 - Reference: [Microsoft - Persistence Ignorance](https://learn.microsoft.com/en-us/dotnet/architecture/microservices/microservice-ddd-cqrs-patterns/infrastructure-persistence-layer-design#the-persistence-ignorance-principle)
 **Wikipedia Definition:**
 - "Persistence ignorance is the ability of a class to be used without any underlying persistence mechanism"
 - Objects don't know if/how they'll be stored
 - Reference: [Wikipedia - Persistence Ignorance](https://en.wikipedia.org/wiki/Persistence_ignorance)
 ### Eric Evans: DDD and Persistence
 **Domain-Driven Design** (2003)
 - Repositories abstract away persistence details
 - Domain model should not reference ORM or database concepts
 - Reference: Already covered in Section 6 - Repository Pattern
 **Key Quote:**
 - "The domain layer should be kept clean of all technical concerns"
 - ORM annotations violate this principle
 - Reference: [Clean Architecture and DDD](https://herbertograca.com/2017/11/16/explicit-architecture-01-ddd-hexagonal-onion-clean-cqrs-how-i-put-it-all-together/)
 ### Clean Architecture Alignment
 **Robert C. Martin:**
 - "The database is a detail"
 - Domain entities should not depend on persistence frameworks
 - Use Repository interfaces to abstract persistence
 - Reference: [Clean Architecture Book](https://www.amazon.com/Clean-Architecture-Craftsmans-Software-Structure/dp/0134494164)
 ### Practical Implementation
 **Two-Model Approach:**
 - Domain Model: Pure business objects
 - Persistence Model: ORM-annotated entities
 - Mappers translate between them
 - Reference: [Microsoft - Infrastructure Layer](https://learn.microsoft.com/en-us/dotnet/architecture/microservices/microservice-ddd-cqrs-patterns/infrastructure-persistence-layer-design)
 **Benefits:**
 - Domain model can evolve independently of database schema
 - Easier testing (no ORM required)
 - Database can be changed without affecting domain
 - Reference: [Enterprise Craftsmanship - Persistence Ignorance](https://enterprisecraftsmanship.com/posts/persistence-ignorance/)
 ---
 ## 22. Null Object Pattern
 ### Original Pattern
 **Pattern Languages of Program Design 3** (1997)
 - Author: Bobby Woolf
 - Chapter: "Null Object"
 - Publisher: Addison-Wesley
 - ISBN: 978-0201310115
 - Reference: [Wikipedia - Null Object Pattern](https://en.wikipedia.org/wiki/Null_object_pattern)
 **Definition:**
 - "A Null Object provides a 'do nothing' behavior, hiding the details from its collaborators"
 - Replaces null checks with polymorphism
 - Reference: [Refactoring Guru - Null Object](https://refactoring.guru/introduce-null-object)
 ### Martin Fowler's Coverage
 **Refactoring Book** (1999, 2018)
 - "Introduce Null Object" refactoring
 - "Replace conditional logic that checks for null with a null object"
 - Reference: [Refactoring Catalog](https://refactoring.com/catalog/introduceNullObject.html)
 **Special Case Pattern:**
 - More general pattern that includes Null Object
 - "A subclass that provides special behavior for particular cases"
 - Reference: [Martin Fowler - Special Case](https://martinfowler.com/eaaCatalog/specialCase.html)
 ### Benefits
 **Eliminates Null Checks:**
 - Reduces cyclomatic complexity
 - Cleaner, more readable code
 - Follows "Tell, Don't Ask" principle
 - Reference: [SourceMaking - Null Object](https://sourcemaking.com/design_patterns/null_object)
 **Polymorphism Over Conditionals:**
 - Null Object responds to same interface as real object
 - Default/neutral behavior instead of null checks
 - Reference: [C2 Wiki - Null Object](https://wiki.c2.com/?NullObject)
 ### When to Use
 **Good Candidates:**
 - Objects frequently checked for null
 - Null represents "absence" with sensible default behavior
 - Reference: [Baeldung - Null Object Pattern](https://www.baeldung.com/java-null-object-pattern)
 **Cautions:**
 - Don't use when null has semantic meaning
 - Can hide bugs if misapplied
 - Reference: [Stack Overflow - Null Object Considerations](https://stackoverflow.com/questions/1274792/is-the-null-object-pattern-a-bad-practice)
 ---
 ## 23. Primitive Obsession
 ### Code Smell Definition
 **Martin Fowler: Refactoring** (1999, 2018)
 - Primitive Obsession is a code smell
 - "Using primitives instead of small objects for simple tasks"
 - Reference: [Refactoring Catalog](https://refactoring.com/catalog/)
 **Wikipedia Definition:**
 - "Using primitive data types to represent domain ideas"
 - Example: Using string for email, int for money
 - Reference: [Wikipedia - Code Smell](https://en.wikipedia.org/wiki/Code_smell)
 ### Why It's a Problem
 **Lost Type Safety:**
 - String can contain anything, Email cannot
 - Compiler can't catch domain errors
 - Reference: [Refactoring Guru - Primitive Obsession](https://refactoring.guru/smells/primitive-obsession)
 **Scattered Validation:**
 - Same validation repeated in multiple places
 - Violates DRY principle
 - Reference: [SourceMaking - Primitive Obsession](https://sourcemaking.com/refactoring/smells/primitive-obsession)
 **Missing Behavior:**
 - Primitives can't have domain-specific methods
 - Logic lives in services instead of objects
 - Reference: [Enterprise Craftsmanship - Primitive Obsession](https://enterprisecraftsmanship.com/posts/functional-c-primitive-obsession/)
 ### Solutions
 **Replace with Value Objects:**
 - Money instead of decimal
 - Email instead of string
 - PhoneNumber instead of string
 - Reference: Already covered in Section 16 - Value Object Immutability
 **Replace Data Value with Object:**
 - Refactoring: "Replace Data Value with Object"
 - Introduce Parameter Object for related primitives
 - Reference: [Refactoring - Replace Data Value with Object](https://refactoring.com/catalog/replaceDataValueWithObject.html)
 ### Common Primitive Obsession Examples
 **Frequently Misused Primitives:**
 - string for: email, phone, URL, currency code, country code
 - int/decimal for: money, percentage, age, quantity
 - DateTime for: date ranges, business dates
 - Reference: [DDD - Value Objects](https://martinfowler.com/bliki/ValueObject.html)
 ---
 ## 24. Service Locator Anti-pattern
 ### Martin Fowler's Analysis
 **Blog Post: Inversion of Control Containers and the Dependency Injection pattern** (2004)
 - Compares Service Locator with Dependency Injection
 - "With service locator the application class asks for it explicitly by a message to the locator"
 - Reference: [Martin Fowler - Inversion of Control](https://martinfowler.com/articles/injection.html)
 **Service Locator Definition:**
 - "The basic idea behind a service locator is to have an object that knows how to get hold of all of the services that an application might need"
 - Acts as a registry that provides dependencies on demand
 - Reference: [Martin Fowler - Service Locator](https://martinfowler.com/articles/injection.html#UsingAServiceLocator)
 ### Why It's Considered an Anti-pattern
 **Mark Seemann: Dependency Injection in .NET** (2011, 2nd Ed. 2019)
 - Author: Mark Seemann
 - Extensively covers why Service Locator is problematic
 - "Service Locator is an anti-pattern"
 - Reference: [Mark Seemann - Service Locator is an Anti-Pattern](https://blog.ploeh.dk/2010/02/03/ServiceLocatorisanAnti-Pattern/)
 **Hidden Dependencies:**
 - Dependencies are not visible in constructor
 - Makes code harder to understand and test
 - Violates Explicit Dependencies Principle
 - Reference: [DevIQ - Explicit Dependencies](https://deviq.com/principles/explicit-dependencies-principle)
 **Testing Difficulties:**
 - Need to set up global locator for tests
 - Tests become coupled to locator setup
 - Reference: [Stack Overflow - Service Locator Testing](https://stackoverflow.com/questions/1557781/is-service-locator-an-anti-pattern)
 ### Dependency Injection Alternative
 **Constructor Injection:**
 - Dependencies declared in constructor
 - Compiler enforces dependency provision
 - Clear, testable code
 - Reference: Already covered in Section 6 - Repository Pattern
 **Benefits over Service Locator:**
 - Explicit dependencies
 - Easier testing (just pass mocks)
 - IDE support for navigation
 - Compile-time checking
 - Reference: [Martin Fowler - Constructor Injection](https://martinfowler.com/articles/injection.html#ConstructorInjectionWithPicocontainer)
 ---
 ## 25. Double Dispatch and Visitor Pattern
 ### Gang of Four: Visitor Pattern
 **Design Patterns** (1994)
 - Authors: Gang of Four
 - Visitor Pattern chapter
 - "Represent an operation to be performed on the elements of an object structure"
 - Reference: [Wikipedia - Visitor Pattern](https://en.wikipedia.org/wiki/Visitor_pattern)
 **Intent:**
 - "Lets you define a new operation without changing the classes of the elements on which it operates"
 - Separates algorithms from object structure
 - Reference: [Refactoring Guru - Visitor](https://refactoring.guru/design-patterns/visitor)
 ### Double Dispatch Mechanism
 **Definition:**
 - "A mechanism that dispatches a function call to different concrete functions depending on the runtime types of two objects involved in the call"
 - Visitor pattern uses double dispatch
 - Reference: [Wikipedia - Double Dispatch](https://en.wikipedia.org/wiki/Double_dispatch)
 **How It Works:**
 1. Client calls element.accept(visitor)
 2. Element calls visitor.visit(this) - first dispatch
 3. Correct visit() overload selected - second dispatch
 - Reference: [SourceMaking - Visitor](https://sourcemaking.com/design_patterns/visitor)
 ### When to Use
 **Good Use Cases:**
 - Operations on complex object structures
 - Many distinct operations needed
 - Object structure rarely changes but operations change often
 - Reference: [Refactoring Guru - Visitor Use Cases](https://refactoring.guru/design-patterns/visitor)
 **Alternative to Type Checking:**
 - Replace instanceof/typeof checks with polymorphism
 - More maintainable and extensible
 - Reference: [Replace Conditional with Polymorphism](https://refactoring.guru/replace-conditional-with-polymorphism)
 ### Trade-offs
 **Advantages:**
 - Open/Closed Principle for new operations
 - Related operations grouped in one class
 - Accumulate state while traversing
 - Reference: [GoF Design Patterns](https://www.amazon.com/Design-Patterns-Elements-Reusable-Object-Oriented/dp/0201633612)
 **Disadvantages:**
 - Adding new element types requires changing all visitors
 - May break encapsulation (visitors need access to element internals)
 - Reference: [C2 Wiki - Visitor Pattern](https://wiki.c2.com/?VisitorPattern)
 ---
 ## 26. Entity Identity
 ### Eric Evans: Domain-Driven Design (2003)
 **Entity Definition:**
 - "An object that is not defined by its attributes, but rather by a thread of continuity and its identity"
 - "Some objects are not defined primarily by their attributes. They represent a thread of identity"
 - Reference: [Martin Fowler - Evans Classification](https://martinfowler.com/bliki/EvansClassification.html)
 **Identity Characteristics:**
 - Unique within the system
 - Stable over time (doesn't change)
 - Survives state changes
 - Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
 ### Vaughn Vernon: Identity Implementation
 **Implementing Domain-Driven Design** (2013)
 - Chapter 5: "Entities"
 - Detailed coverage of identity strategies
 - "The primary characteristic of an Entity is that it has a unique identity"
 - Reference: [Vaughn Vernon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
 **Identity Types:**
 - Natural keys (SSN, email)
 - Surrogate keys (UUID, auto-increment)
 - Domain-generated IDs
 - Reference: [Microsoft - Entity Keys](https://learn.microsoft.com/en-us/ef/core/modeling/keys)
 ### Identity Best Practices
 **Immutability of Identity:**
 - Identity should never change after creation
 - Use readonly/final fields
 - Reference: [StackExchange - Mutable Entity ID](https://softwareengineering.stackexchange.com/questions/375765/is-it-bad-practice-to-have-mutable-entity-ids)
 **Value Object for Identity:**
 - Wrap identity in Value Object (UserId, OrderId)
 - Type safety prevents mixing IDs
 - Can include validation logic
 - Reference: [Enterprise Craftsmanship - Strongly Typed IDs](https://enterprisecraftsmanship.com/posts/strongly-typed-ids/)
 **Equality Based on Identity:**
 - Entity equality should compare only identity
 - Not all attributes
 - Reference: [Vaughn Vernon - Entity Equality](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
 ---
 ## 27. Saga Pattern
 ### Original Research
 **Paper: Sagas** (1987)
 - Authors: Hector Garcia-Molina and Kenneth Salem
 - Published: ACM SIGMOD Conference
 - Introduced Sagas for long-lived transactions
 - Reference: [ACM Digital Library - Sagas](https://dl.acm.org/doi/10.1145/38713.38742)
 **Definition:**
 - "A saga is a sequence of local transactions where each transaction updates data within a single service"
 - Alternative to distributed transactions
 - Reference: [Microsoft - Saga Pattern](https://learn.microsoft.com/en-us/azure/architecture/reference-architectures/saga/saga)
 ### Chris Richardson: Microservices Patterns
 **Book: Microservices Patterns** (2018)
 - Author: Chris Richardson
 - Publisher: Manning
 - ISBN: 978-1617294549
 - Chapter 4: "Managing Transactions with Sagas"
 - Reference: [Manning - Microservices Patterns](https://www.manning.com/books/microservices-patterns)
 **Saga Types:**
 1. **Choreography**: Each service publishes events that trigger next steps
 2. **Orchestration**: Central coordinator tells services what to do
 - Reference: [Microservices.io - Saga](https://microservices.io/patterns/data/saga.html)
 ### Compensating Transactions
 **Core Concept:**
 - Each step has a compensating action to undo it
 - If step N fails, compensate steps N-1, N-2, ..., 1
 - Reference: [AWS - Saga Pattern](https://docs.aws.amazon.com/prescriptive-guidance/latest/modernization-data-persistence/saga-pattern.html)
 **Compensation Examples:**
 - CreateOrder → DeleteOrder
 - ReserveInventory → ReleaseInventory
 - ChargePayment → RefundPayment
 - Reference: [Microsoft - Compensating Transactions](https://learn.microsoft.com/en-us/azure/architecture/patterns/compensating-transaction)
 ### Trade-offs
 **Advantages:**
 - Works across service boundaries
 - No distributed locks
 - Services remain autonomous
 - Reference: [Chris Richardson - Saga](https://chrisrichardson.net/post/microservices/patterns/data/2019/07/22/design-sagas.html)
 **Challenges:**
 - Complexity of compensation logic
 - Eventual consistency
 - Debugging distributed sagas

 ## 28. Anti-Corruption Layer
 ### Eric Evans: Domain-Driven Design (2003)
 **Original Definition:**
 - Chapter 14: "Maintaining Model Integrity"
 - "Create an isolating layer to provide clients with functionality in terms of their own domain model"
 - Protects your model from external/legacy models
 - Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
 **Purpose:**
 - "The translation layer between a new system and an external system"
 - Prevents external model concepts from leaking in
 - Reference: [Martin Fowler - Anti-Corruption Layer](https://martinfowler.com/bliki/AntiCorruptionLayer.html)
 ### Microsoft Guidance
 **Azure Architecture Center:**
 - "Implement a facade or adapter layer between different subsystems that don't share the same semantics"
 - Isolate subsystems by placing an anti-corruption layer between them
 - Reference: [Microsoft - ACL Pattern](https://learn.microsoft.com/en-us/azure/architecture/patterns/anti-corruption-layer)
 **When to Use:**
 - Integrating with legacy systems
 - Migrating from monolith to microservices
 - Working with third-party APIs
 - Reference: [Microsoft - ACL When to Use](https://learn.microsoft.com/en-us/azure/architecture/patterns/anti-corruption-layer#when-to-use-this-pattern)
 ### Components of ACL
 **Facade:**
 - Simplified interface to external system
 - Hides complexity from domain
 - Reference: [Refactoring Guru - Facade](https://refactoring.guru/design-patterns/facade)
 **Adapter:**
 - Translates between interfaces
 - Maps external model to domain model
 - Reference: [Refactoring Guru - Adapter](https://refactoring.guru/design-patterns/adapter)
 **Translator:**
 - Converts data structures
 - Maps field names and types
 - Handles semantic differences
 - Reference: [Evans DDD - Model Translation](https://www.domainlanguage.com/)
 ### Benefits
 **Isolation:**
 - Changes to external system don't ripple through domain
 - Domain model remains pure
 - Reference: [Microsoft - ACL Benefits](https://learn.microsoft.com/en-us/azure/architecture/patterns/anti-corruption-layer)
 **Gradual Migration:**
 - Replace legacy components incrementally
 - Strangler Fig pattern compatibility
 - Reference: [Martin Fowler - Strangler Fig](https://martinfowler.com/bliki/StranglerFigApplication.html)

 ## 29. Ubiquitous Language
 ### Eric Evans: Domain-Driven Design (2003)
 **Original Definition:**
 - Chapter 2: "Communication and the Use of Language"
 - "A language structured around the domain model and used by all team members"
 - "The vocabulary of that Ubiquitous Language includes the names of classes and prominent operations"
 - Reference: [Martin Fowler - Ubiquitous Language](https://martinfowler.com/bliki/UbiquitousLanguage.html)
 **Key Principles:**
 - Shared by developers and domain experts
 - Used in code, conversations, and documentation
 - Changes to language reflect model changes
 - Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
 ### Why It Matters
 **Communication Benefits:**
 - Reduces translation between business and tech
 - Catches misunderstandings early
 - Domain experts can read code names
 - Reference: [InfoQ - Ubiquitous Language](https://www.infoq.com/articles/ddd-ubiquitous-language/)
 **Design Benefits:**
 - Model reflects real domain concepts
 - Code becomes self-documenting
 - Easier onboarding for new team members
 - Reference: [Vaughn Vernon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
 ### Building Ubiquitous Language
 **Glossary:**
 - Document key terms and definitions
 - Keep updated as understanding evolves
 - Reference: [DDD Community - Glossary](https://thedomaindrivendesign.io/glossary/)
 **Event Storming:**
 - Collaborative workshop technique
 - Discover domain events and concepts
 - Build shared understanding and language
 - Reference: [Alberto Brandolini - Event Storming](https://www.eventstorming.com/)
 ### Common Pitfalls
 **Inconsistent Terminology:**
 - Same concept with different names (Customer/Client/User)
 - Different concepts with same name
 - Reference: [Domain Language - Building UL](https://www.domainlanguage.com/)
 **Technical Terms in Domain:**
 - "DTO", "Entity", "Repository" are technical
 - Domain should use business terms
 - Reference: [Evans DDD - Model-Driven Design](https://www.domainlanguage.com/)

 ## Version 0.19.0 - XML Tool Format Refactor 🔄 ✅
 **Priority:** HIGH
 **Status:** Complete (v0.19.0 released)
 Refactoring: transition to pure XML format for tool calls (as in CONCEPT.md).
 ### Current Problem
 OllamaClient uses Ollama native tool calling (JSON Schema), while ResponseParser implements XML parsing. This creates confusion and doesn't match CONCEPT.md.
 ### 0.19.1 - OllamaClient Refactor
 ```typescript
 // src/infrastructure/llm/OllamaClient.ts
 // BEFORE:
 // - Pass tools in Ollama SDK format
 // - Extract tool_calls from response.message.tool_calls
 // AFTER:
 // - DON'T pass tools to SDK
 // - Tools described in system prompt as XML
 // - LLM returns XML in content
 // - Parse via ResponseParser
 ```
 **Changes:**
 - [x] Remove `convertTools()` method
 - [x] Remove `extractToolCalls()` method
 - [x] Remove `tools` from `client.chat()` call
 - [x] Return only `content` without `toolCalls`
 ### 0.19.2 - System Prompt Update
 ```typescript
 // src/infrastructure/llm/prompts.ts
 // Add full XML format description to SYSTEM_PROMPT:
 const TOOL_FORMAT_INSTRUCTIONS = `
 ## Tool Calling Format
 When you need to use a tool, format your call as XML:
 <tool_call name="tool_name">
  <param_name>value</param_name>
  <another_param>value</another_param>
 </tool_call>
 Examples:
 <tool_call name="get_lines">
  <path>src/index.ts</path>
  <start>1</start>
  <end>50</end>
 </tool_call>
 <tool_call name="edit_lines">
  <path>src/utils.ts</path>
  <start>10</start>
  <end>15</end>
  <content>const newCode = "hello";</content>
 </tool_call>
 You can use multiple tool calls in one response.
 Always wait for tool results before making conclusions.
 `
 ```
 **Changes:**
 - [x] Add `TOOL_FORMAT_INSTRUCTIONS` to prompts.ts
 - [x] Include in `SYSTEM_PROMPT`
 - [x] Add examples for all 18 tools
 ### 0.19.3 - HandleMessage Simplification
 ```typescript
 // src/application/use-cases/HandleMessage.ts
 // BEFORE:
 // const response = await this.llm.chat(messages)
 // const parsed = parseToolCalls(response.content)
 // AFTER:
 // const response = await this.llm.chat(messages)  // without tools
 // const parsed = parseToolCalls(response.content) // single source
 ```
 **Changes:**
 - [x] Remove tool definitions from `llm.chat()`
 - [x] ResponseParser — single source of tool calls
 - [x] Simplify processing logic
 ### 0.19.4 - ILLMClient Interface Update
 ```typescript
 // src/domain/services/ILLMClient.ts
 // BEFORE:
 interface ILLMClient {
    chat(messages: ChatMessage[], tools?: ToolDef[]): Promise<LLMResponse>
 }
 // AFTER:
 interface ILLMClient {
    chat(messages: ChatMessage[]): Promise<LLMResponse>
    // tools no longer passed - they're in system prompt
 }
 ```
 **Changes:**
 - [x] Remove `tools` parameter from `chat()`
 - [x] Remove `toolCalls` from `LLMResponse` (parsed from content)
 - [x] Update all implementations
 ### 0.19.5 - ResponseParser Enhancements
 ```typescript
 // src/infrastructure/llm/ResponseParser.ts
 // Improvements:
 // - Better error handling for parsing
 // - CDATA support for multiline content
 // - Tool name validation
 ```
 **Changes:**
 - [x] Add `<![CDATA[...]]>` support for content
 - [x] Validation: tool name must be from known list
 - [x] Improve parsing error messages
 **Tests:**
 - [x] Update OllamaClient tests
 - [x] Update HandleMessage tests
 - [x] Add ResponseParser tests for edge cases

 ## Version 0.24.0 - Rich Initial Context 📋
 **Priority:** HIGH
 **Status:** In Progress (2/4 complete)
 Enhance initial context for LLM: add function signatures, interface field types, and enum values. This allows LLM to answer questions about types and parameters without tool calls.
 ### 0.24.1 - Function Signatures with Types ⭐ ✅
 **Problem:** Currently LLM only sees function names: `fn: getUser, createUser`
 **Solution:** Show full signatures: `async getUser(id: string): Promise<User>`
 ```typescript
 // src/infrastructure/llm/prompts.ts changes
 // BEFORE:
 // - src/services/user.ts [fn: getUser, createUser]
 // AFTER:
 // ### src/services/user.ts
 // - async getUser(id: string): Promise<User>
 // - async createUser(data: UserDTO): Promise<User>
 // - validateEmail(email: string): boolean
 ```
 **Changes:**
 - [x] Extend `FunctionInfo` in FileAST for parameter types and return type (already existed)
 - [x] Update `ASTParser.ts` to extract parameter types and return types (arrow functions fixed)
 - [x] Update `formatFileSummary()` in prompts.ts to output signatures
 - [x] Add `includeSignatures: boolean` option to config
 **Why:** LLM won't hallucinate parameters and return types.
 ### 0.24.2 - Interface/Type Field Definitions ⭐ ✅
 **Problem:** LLM only sees `interface: User, UserDTO`
 **Solution:** Show fields: `User { id: string, name: string, email: string }`
 ```typescript
 // BEFORE:
 // - src/types/user.ts [interface: User, UserDTO]
 // AFTER:
 // ### src/types/user.ts
 // - interface User { id: string, name: string, email: string, createdAt: Date }
 // - interface UserDTO { name: string, email: string }
 // - type UserId = string
 ```
 **Changes:**
 - [x] Extend `InterfaceInfo` in FileAST for field types (already existed)
 - [x] Update `ASTParser.ts` to extract interface fields (already existed)
 - [x] Update `formatFileSummary()` to output fields
 - [x] Handle type aliases with their definitions
 **Why:** LLM knows data structure, won't invent fields.
 ### 0.24.3 - Enum Value Definitions
 **Problem:** LLM only sees `type: Status`
 **Solution:** Show values: `Status { Active=1, Inactive=0, Pending=2 }`
 ```typescript
 // BEFORE:
 // - src/types/enums.ts [type: Status, Role]
 // AFTER:
 // ### src/types/enums.ts
 // - enum Status { Active=1, Inactive=0, Pending=2 }
 // - enum Role { Admin="admin", User="user" }
 ```
 **Changes:**
 - [ ] Add `EnumInfo` to FileAST with members and values
 - [ ] Update `ASTParser.ts` to extract enum members
 - [ ] Update `formatFileSummary()` to output enum values
 **Why:** LLM knows valid enum values.
 ### 0.24.4 - Decorator Extraction
 **Problem:** LLM doesn't see decorators (important for NestJS, Angular)
 **Solution:** Show decorators in context
 ```typescript
 // AFTER:
 // ### src/controllers/user.controller.ts
 // - @Controller('users') class UserController
 // - @Get(':id') async getUser(id: string): Promise<User>
 // - @Post() @Body() async createUser(data: UserDTO): Promise<User>
 ```
 **Changes:**
 - [ ] Add `decorators: string[]` to FunctionInfo and ClassInfo
 - [ ] Update `ASTParser.ts` to extract decorators
 - [ ] Update context to display decorators
 **Why:** LLM understands routing, DI, guards in NestJS/Angular.
 **Tests:**
 - [ ] Unit tests for enhanced ASTParser
 - [ ] Unit tests for new context format
 - [ ] Integration tests for full flow
 ---
 ## Version 0.25.0 - Graph Metrics in Context 📊
 **Priority:** MEDIUM
 **Status:** Planned
 Add graph metrics to initial context: dependency graph, circular dependencies, impact score.
 ### 0.25.1 - Inline Dependency Graph
 **Problem:** LLM doesn't see file relationships without tool calls
 **Solution:** Show dependency graph in context
 ```typescript
 // Add to initial context:
 // ## Dependency Graph
 // src/services/user.ts: → types/user, utils/validation ← controllers/user, api/routes
 // src/services/auth.ts: → services/user, utils/jwt ← controllers/auth
 // src/utils/validation.ts: ← services/user, services/auth, controllers/*
 ```
 **Changes:**
 - [ ] Add `formatDependencyGraph()` to prompts.ts
 - [ ] Use data from `FileMeta.dependencies` and `FileMeta.dependents`
 - [ ] Group by hub files (many connections)
 - [ ] Add `includeDepsGraph: boolean` option to config
 **Why:** LLM sees architecture without tool call.
 ### 0.25.2 - Circular Dependencies in Context
 **Problem:** Circular deps are computed but not shown in context
 **Solution:** Show cycles immediately
 ```typescript
 // Add to initial context:
 // ## ⚠️ Circular Dependencies
 // - services/user → services/auth → services/user
 // - utils/a → utils/b → utils/c → utils/a
 ```
 **Changes:**
 - [ ] Add `formatCircularDeps()` to prompts.ts
 - [ ] Get circular deps from IndexBuilder
 - [ ] Store in Redis as separate key or in meta
 **Why:** LLM immediately sees architecture problems.
 ### 0.25.3 - Impact Score
 **Problem:** LLM doesn't know which files are critical
 **Solution:** Show impact score (% of codebase that depends on file)
 ```typescript
 // Add to initial context:
 // ## High Impact Files
 // | File | Impact | Dependents |
 // |------|--------|------------|
 // | src/utils/validation.ts | 67% | 12 files |
 // | src/types/user.ts | 45% | 8 files |
 // | src/services/user.ts | 34% | 6 files |
 ```
 **Changes:**
 - [ ] Add `impactScore: number` to FileMeta (0-100)
 - [ ] Compute in MetaAnalyzer: (transitiveDepByCount / totalFiles) * 100
 - [ ] Add `formatHighImpactFiles()` to prompts.ts
 - [ ] Show top-10 high impact files
 **Why:** LLM understands which files are critical for changes.
 ### 0.25.4 - Transitive Dependencies Count
 **Problem:** Currently only counting direct dependencies
 **Solution:** Add transitive dependencies to meta
 ```typescript
 // FileMeta additions:
 interface FileMeta {
    // existing...
    transitiveDepCount: number;    // how many files depend on this (transitively)
    transitiveDepByCount: number;  // how many files this depends on (transitively)
 }
 ```
 **Changes:**
 - [ ] Add `computeTransitiveDeps()` to MetaAnalyzer
 - [ ] Use DFS with memoization for efficiency
 - [ ] Store in FileMeta
 **Tests:**
 - [ ] Unit tests for graph metrics computation
 - [ ] Unit tests for new context sections
 - [ ] Performance tests for large codebases

 4. **Efficiency**: Minimize context usage. Request only necessary code sections.
 ## Tool Calling Format
 When you need to use a tool, format your call as XML:
 <tool_call name="tool_name">
  <param_name>value</param_name>
  <another_param>value</another_param>
 </tool_call>
 You can call multiple tools in one response. Always wait for tool results before making conclusions.
 **Examples:**
 <tool_call name="get_lines">
  <path>src/index.ts</path>
  <start>1</start>
  <end>50</end>
 </tool_call>
 <tool_call name="edit_lines">
  <path>src/utils.ts</path>
  <start>10</start>
  <end>15</end>
  <content>const newCode = "hello";</content>
