+## 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:**

+## 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

+## 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

+## 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

+## Version 0.24.0 - Rich Initial Context 📋 ✅
+
+**Priority:** HIGH
+**Status:** Complete (v0.24.0 released)
+
+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:**
+- [x] Add `EnumInfo` to FileAST with members and values
+- [x] Update `ASTParser.ts` to extract enum members
+- [x] 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:**
+- [x] Add `decorators: string[]` to FunctionInfo, MethodInfo, and ClassInfo
+- [x] Update `ASTParser.ts` to extract decorators via `extractNodeDecorators()` and `extractDecoratorsFromSiblings()`
+- [x] Update `prompts.ts` to display decorators via `formatDecoratorsPrefix()`
+
+**Why:** LLM understands routing, DI, guards in NestJS/Angular.
+
+**Tests:**
+- [x] Unit tests for ASTParser decorator extraction (14 tests)
+- [x] Unit tests for prompts decorator formatting (6 tests)
+
+---
+
+## Version 0.27.0 - Inline Dependency Graph 📊 ✅
+
+**Priority:** MEDIUM
+**Status:** Complete (v0.27.0 released)
+
+### Description
+
+**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:**
+- [x] Add `formatDependencyGraph()` to prompts.ts
+- [x] Use data from `FileMeta.dependencies` and `FileMeta.dependents`
+- [x] Group by hub files (many connections)
+- [x] Add `includeDepsGraph: boolean` option to config
+
+**Tests:**
+- [x] Unit tests for formatDependencyGraph() (16 tests)
+- [x] Unit tests for includeDepsGraph config option (5 tests)
+
+**Why:** LLM sees architecture without tool call.
+
+---
+
+## Version 0.28.0 - Circular Dependencies in Context 🔄 ✅
+
+**Priority:** MEDIUM
+**Status:** Complete (v0.28.0 released)
+
+### Description
+
+**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:**
+- [x] Add `formatCircularDeps()` to prompts.ts
+- [x] Add `includeCircularDeps: boolean` config option (default: true)
+- [x] Add `circularDeps: string[][]` parameter to `BuildContextOptions`
+- [x] Integrate into `buildInitialContext()`
+
+**Tests:**
+- [x] Unit tests for formatCircularDeps() (12 tests)
+- [x] Unit tests for buildInitialContext with includeCircularDeps (6 tests)
+- [x] Unit tests for includeCircularDeps config option (5 tests)
+
+**Why:** LLM immediately sees architecture problems.
+
+---
+
+## Version 0.29.0 - Impact Score 📈 ✅
+
+**Priority:** MEDIUM
+**Status:** Complete (v0.29.0 released)
+
+### Description
+
+**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:**
+- [x] Add `impactScore: number` to FileMeta (0-100)
+- [x] Compute in MetaAnalyzer: (dependents.length / (totalFiles - 1)) * 100
+- [x] Add `formatHighImpactFiles()` to prompts.ts
+- [x] Show top-10 high impact files
+- [x] Add `includeHighImpactFiles` config option (default: true)
+
+**Tests:**
+- [x] Unit tests for calculateImpactScore (9 tests)
+- [x] Unit tests for formatHighImpactFiles (14 tests)
+- [x] Unit tests for includeHighImpactFiles config (5 tests)
+
+**Why:** LLM understands which files are critical for changes.
+
+---
+
+## Version 0.30.0 - Transitive Dependencies Count 🔢 ✅
+
+**Priority:** MEDIUM
+**Status:** Complete (v0.30.0 released)
+
+### Description
+
+**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:**
+- [x] Add `transitiveDepCount` and `transitiveDepByCount` to FileMeta
+- [x] Add `computeTransitiveCounts()` to MetaAnalyzer
+- [x] Add `getTransitiveDependents()` with DFS and cycle detection
+- [x] Add `getTransitiveDependencies()` with DFS and cycle detection
+- [x] Use top-level caching for efficiency
+- [x] Handle circular dependencies gracefully (exclude self from count)
+
+**Tests:**
+- [x] Unit tests for transitive dependencies computation (14 tests)
+- [x] Tests for circular dependencies
+- [x] Tests for diamond dependency patterns
+- [x] Tests for deep dependency chains
+- [x] Cache behavior tests

-## Core Principles
+## When to Use Tools
 
-1. **Lazy Loading**: You don't have the full code in context. Use tools to fetch exactly what you need.
-2. **Precision**: Always verify file paths and line numbers before making changes.
-3. **Safety**: Confirm destructive operations. Never execute dangerous commands.
-4. **Efficiency**: Minimize context usage. Request only necessary code sections.
+**Use tools** when the user asks about:
+- Code content (files, functions, classes)
+- Project structure
+- TODOs, complexity, dependencies
+- Git status, diffs, commits
+- Running commands or tests
 
-## Tool Calling Format
+**Do NOT use tools** for:
+- Greetings ("Hello", "Hi", "Thanks")
+- General questions not about this codebase
+- Clarifying questions back to the user
 
-When you need to use a tool, format your call as XML:
+## MANDATORY: Tools for Code Questions
 
-<tool_call name="tool_name">
-  <param_name>value</param_name>
-  <another_param>value</another_param>
-</tool_call>
+**CRITICAL:** You have ZERO code in your context. To answer ANY question about code, you MUST first call a tool.
 
-You can call multiple tools in one response. Always wait for tool results before making conclusions.
-
-**Examples:**
+**WRONG:**
+User: "What's in src/index.ts?"
+Assistant: "The file likely contains..." ← WRONG! Call a tool!
 
+**CORRECT:**
+User: "What's in src/index.ts?"
 <tool_call name="get_lines">
-  <path>src/index.ts</path>
-  <start>1</start>
-  <end>50</end>
+<path>src/index.ts</path>
 </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 Format
+
+Output this XML format. Do NOT explain before calling - just output the XML:
+
+<tool_call name="TOOL_NAME">
+<param1>value1</param1>
+<param2>value2</param2>
 </tool_call>
 
-<tool_call name="find_references">
-  <symbol>getUserById</symbol>
+## Example Interactions
+
+**Example 1 - Reading a file:**
+User: "Show me the main function in src/app.ts"
+<tool_call name="get_function">
+<path>src/app.ts</path>
+<name>main</name>
+</tool_call>
+
+**Example 2 - Finding TODOs:**
+User: "Are there any TODO comments?"
+<tool_call name="get_todos">
+</tool_call>
+
+**Example 3 - Project structure:**
+User: "What files are in this project?"
+<tool_call name="get_structure">
+<path>.</path>
 </tool_call>
 
 ## Available Tools

-- \`run_tests(path?, filter?, watch?)\`: Run the test suite
+## Rules
 
-## Response Guidelines
+1. **ALWAYS call a tool first** when asked about code - you cannot see any files
+2. **Output XML directly** - don't say "I will use..." just output the tool call
+3. **Wait for results** before making conclusions
+4. **Be concise** in your responses
+5. **Verify before editing** - always read code before modifying it
+6. **Stay safe** - never execute destructive commands without user confirmation`
 
-1. **Be concise**: Don't repeat information already in context.
-2. **Show your work**: Explain what tools you're using and why.
-3. **Verify before editing**: Always read the target code before modifying it.
-4. **Handle errors gracefully**: If a tool fails, explain what went wrong and suggest alternatives.
+/**
+ * Tool usage reminder - appended to messages to reinforce tool usage.
+ * This is added as the last system message before LLM call.
+ */
+export const TOOL_REMINDER = `⚠️ REMINDER: To answer this question, you MUST use a tool first.
+Output the <tool_call> XML directly. Do NOT describe what you will do - just call the tool.
 
-## Code Editing Rules
-
-1. Always use \`get_lines\` or \`get_function\` before \`edit_lines\`.
-2. Provide exact line numbers for edits.
-3. For large changes, break into multiple small edits.
-4. After editing, suggest running tests if available.
-
-## Safety Rules
-
-1. Never execute commands that could harm the system.
-2. Never expose sensitive data (API keys, passwords).
-3. Always confirm file deletions and destructive git operations.
-4. Stay within the project directory.
-
-When you need to perform an action, use the appropriate tool. Think step by step about what information you need and which tools will provide it most efficiently.`
+Example - if asked about a file, output:
+<tool_call name="get_lines">
+<path>the/file/path.ts</path>
+</tool_call>`
