 ## [0.7.4] - 2025-11-25
 ### Fixed
 - 🐛 **TypeScript-aware hardcode detection** - dramatically reduces false positives by 35.7%:
  - Ignore strings in TypeScript union types (`type Status = 'active' | 'inactive'`)
  - Ignore strings in interface property types (`interface { mode: 'development' | 'production' }`)
  - Ignore strings in type assertions (`as 'read' | 'write'`)
  - Ignore strings in typeof checks (`typeof x === 'string'`)
  - Ignore strings in Symbol() calls for DI tokens (`Symbol('LOGGER')`)
  - Ignore strings in dynamic import() calls (`import('../../module.js')`)
  - Exclude tokens.ts/tokens.js files completely (DI container files)
  - Tested on real-world TypeScript project: 985 → 633 issues (352 false positives eliminated)
 - ✅ **Added 13 new tests** for TypeScript type context filtering
 ## [0.7.3] - 2025-11-25
 ### Fixed
 - 🐛 **False positive: repository importing its own aggregate:**
  - Added `isInternalBoundedContextImport()` method to detect internal imports
  - Imports like `../aggregates/Entity` from `repositories/Repo` are now allowed
  - This correctly allows `ICodeProjectRepository` to import `CodeProject` from the same bounded context
  - Cross-aggregate imports (with multiple `../..`) are still detected as violations
 ## [0.7.2] - 2025-11-25
 ### Fixed
 - 🐛 **False positive: `errors` folder detected as aggregate:**
  - Added `errors` and `exceptions` to `DDD_FOLDER_NAMES` constants
  - Added to `nonAggregateFolderNames` — these folders are no longer detected as aggregates
  - Added to `allowedFolderNames` — imports from `errors`/`exceptions` folders are allowed across aggregates
  - Fixes issue where `domain/code-analysis/errors/` was incorrectly identified as a separate aggregate named "errors"
 ## [0.7.1] - 2025-11-25
 ### Fixed
 - 🐛 **Aggregate Boundary Detection for relative paths:**
  - Fixed regex pattern to support paths starting with `domain/` (without leading `/`)
  - Now correctly detects violations in projects scanned from parent directories
 - 🐛 **Reduced false positives in Repository Pattern detection:**
  - Removed `findAll`, `exists`, `count` from ORM technical methods blacklist
  - These are now correctly recognized as valid domain method names
  - Added `exists`, `count`, `countBy[A-Z]` to domain method patterns
 - 🐛 **Non-aggregate folder exclusions:**
  - Added exclusions for standard DDD folders: `constants`, `shared`, `factories`, `ports`, `interfaces`
  - Prevents false positives when domain layer has shared utilities
 ### Changed
 - ♻️ **Extracted magic strings to constants:**
  - DDD folder names (`entities`, `aggregates`, `value-objects`, etc.) moved to `DDD_FOLDER_NAMES`
  - Repository method suggestions moved to `REPOSITORY_METHOD_SUGGESTIONS`
  - Fallback suggestions moved to `REPOSITORY_FALLBACK_SUGGESTIONS`
 ### Added
 - 📁 **Aggregate boundary test examples:**
  - Added `examples/aggregate-boundary/domain/` with Order, User, Product aggregates
  - Demonstrates cross-aggregate entity reference violations
 ## [0.7.0] - 2025-11-25
 ### Added
 **🔒 Aggregate Boundary Validation**
 New DDD feature to enforce aggregate boundaries and prevent tight coupling between aggregates.
 - ✅ **Aggregate Boundary Detector:**
  - Detects direct entity references across aggregate boundaries

 ## 🔥 Guardian's Unique Advantages
 Guardian has **7 unique features** that no competitor offers:
 ### 1. ✨ Hardcode Detection with AI Suggestions
 **Guardian:**
 ```typescript
 // Detected:
 app.listen(3000)
 // Suggestion:
 💡 Extract to: DEFAULT_PORT
 📁 Location: infrastructure/config/constants.ts
 🤖 AI Prompt: "Extract port 3000 to DEFAULT_PORT constant in config"
 ```
 **Competitors:**
 - SonarQube: Only detects hardcoded secrets (API keys), not magic numbers
 - Others: No hardcode detection at all
 ### 2. 🔌 Framework Leak Detection
 **Guardian:**
 ```typescript
 // domain/entities/User.ts
 import { Request } from 'express'  // ❌ VIOLATION!
 // Detected: Framework leak in domain layer
 // Suggestion: Use dependency injection via interfaces
 ```
 **Competitors:**
 - ArchUnit: Can check via custom rules (not built-in)
 - Others: Not available
 ### 3. 🎭 Entity Exposure Detection
 **Guardian:**
 ```typescript
 // ❌ Bad: Domain entity exposed
 async getUser(): Promise<User> { }
 // ✅ Good: Use DTOs
 async getUser(): Promise<UserDto> { }
 // Guardian detects this automatically!
 ```
 **Competitors:**
 - None have this built-in
 ### 4. 📚 Repository Pattern Validation
 **Guardian:**
 ```typescript
 // Detects ORM types in domain interfaces:
 interface IUserRepository {
    findOne(query: { where: ... })  // ❌ Prisma-specific!
 }
 // Detects concrete repos in use cases:
 constructor(private prisma: PrismaClient) {}  // ❌ VIOLATION!
 ```
 **Competitors:**
 - None validate repository pattern
 ### 5. 🤖 AI-First Workflow
 **Guardian:**
 ```bash
 # Generate AI-friendly fix prompt
 guardian check ./src --format ai-prompt > fix.txt
 # Feed to Claude/GPT:
 "Fix these Guardian violations: $(cat fix.txt)"
 # AI fixes → Run Guardian again → Ship it!
 ```
 **Competitors:**
 - Generic output, not optimized for AI assistants
 ### 6. 🛠️ Auto-Fix for Architecture (v0.9+)
 **Guardian:**
 ```bash
 # Automatically extract hardcodes to constants
 guardian fix ./src --auto
 # Rename files to match conventions
 guardian fix naming ./src --auto
 # Interactive mode
 guardian fix ./src --interactive
 ```
 **Competitors:**
 - ESLint has `--fix` but only for syntax
 - None fix architecture violations
 ### 7. 🎯 DDD Pattern Detection (30+)
 **Guardian Roadmap:**
 - Aggregate boundaries
 - Anemic domain model
 - Domain events
 - Value Object immutability
 - CQRS violations
 - Saga pattern
 - Ubiquitous language
 - And 23+ more DDD patterns!
 **Competitors:**
 - Generic architecture checks only
 - No DDD-specific patterns

 ```typescript
 // AI generates code → Guardian checks → AI fixes → Ship
 // 10x faster than manual review
 ```
 ✅ **Clean Architecture / DDD enforcement**
 ```typescript
 // Guardian understands DDD out-of-the-box
 // SonarQube requires custom rules
 ```
 ✅ **Fast setup (< 5 minutes)**
 ```bash
 npm install -g @samiyev/guardian
 guardian check ./src
 # Done! (vs hours of SonarQube setup)
 ```
 ✅ **Hardcode detection with context**
 ```typescript
 // Guardian knows the difference between:
 const port = 3000        // ❌ Should be constant
 const increment = 1      // ✅ Allowed (semantic)
 ```
 ### Side-by-Side Example
 **Scenario:** Detect hardcoded port in Express app
 ```typescript
 // src/server.ts
 app.listen(3000)
 ```
 **SonarQube:**
 ```
 ❌ No violation (not a secret)
 ```
 **Guardian:**
 ```
 ✅ Hardcode detected:
   Type: magic-number
   Value: 3000
   💡 Suggested: DEFAULT_PORT
   📁 Location: infrastructure/config/constants.ts
   🤖 AI Fix: "Extract 3000 to DEFAULT_PORT constant"
 ```
 ---
 ## vs dependency-cruiser
 ### When dependency-cruiser Wins
 ✅ **Visualization priority**
 ```bash
 # Best-in-class dependency graphs
 depcruise src --output-type dot | dot -T svg > graph.svg
 ```
 ✅ **Custom dependency rules**
 ```javascript
 // Highly flexible rule system
 forbidden: [
  {
    from: { path: '^src/domain' },
    to: { path: '^src/infrastructure' }
  }
 ]
 ```
 ✅ **Multi-framework support**
 ```
 JS, TS, Vue, Svelte, JSX, CoffeeScript
 ```
 ### When Guardian Wins
 ✅ **DDD/Clean Architecture out-of-the-box**
 ```typescript
 // Guardian knows these patterns:
 // - Domain/Application/Infrastructure layers
 // - Entity exposure
 // - Repository pattern
 // - Framework leaks
 // dependency-cruiser: Write custom rules for each
 ```
 ✅ **Hardcode detection**
 ```typescript
 // Guardian finds:
 setTimeout(() => {}, 5000)  // Magic number
 const url = "http://..."    // Magic string
 // dependency-cruiser: Doesn't check this
 ```
 ✅ **AI workflow integration**
 ```bash
 guardian check ./src --format ai-prompt
 # Optimized for Claude/GPT
 depcruise src
 # Generic output
 ```
 ### Complementary Usage
 **Best approach:** Use both!
 ```bash
 # Guardian for architecture + hardcode
 guardian check ./src
 # dependency-cruiser for visualization
 depcruise src --output-type svg > architecture.svg
 ```
 **Coming in Guardian v0.7.0:**
 ```bash
 # Guardian will have built-in visualization!
 guardian visualize ./src --output architecture.svg
 ```
 ---
 ## vs ArchUnit (Java)
 ### When ArchUnit Wins
 ✅ **Java projects**
 ```java
 // ArchUnit is built for Java
@ArchTest
 void domainShouldNotDependOnInfrastructure(JavaClasses classes) {
    noClasses().that().resideInPackage("..domain..")
        .should().dependOnClassesThat().resideInPackage("..infrastructure..")
        .check(classes);
 }
 ```
 ✅ **Test-based architecture validation**
 ```java
 // Architecture rules = unit tests
 // Runs in your CI with other tests
 ```
 ✅ **Mature Java ecosystem**
 ```
 Spring Boot, Hibernate, JPA patterns
 Built-in rules for layered/onion architecture
 ```
 ### When Guardian Wins
 ✅ **TypeScript/JavaScript projects**
 ```typescript
 // Guardian is built for TypeScript
 // ArchUnit doesn't support TS
 ```
 ✅ **AI coding workflow**
 ```bash
 # Guardian → AI → Fix → Ship
 # ArchUnit is test-based (slower feedback)
 ```
 ✅ **Zero-config DDD**
 ```bash
 guardian check ./src
 # Works immediately with DDD structure
 # ArchUnit requires writing tests for each rule
 ```
 ### Philosophical Difference
 **ArchUnit:**
 ```java
 // Architecture = Tests
 // You write explicit tests for each rule
 ```
 **Guardian:**
 ```bash
 # Architecture = Linter
 # Pre-configured DDD rules out-of-the-box
 ```
 ---
 ## vs FTA (Fast TypeScript Analyzer)
 ### When FTA Wins
 ✅ **Complexity metrics focus**
 ```bash
 # FTA provides:
 # - Cyclomatic complexity
 # - Halstead metrics
 # - Line counts
 # - Technical debt estimation
 ```
 ✅ **Performance (Rust-based)**
 ```
 FTA: 1600 files/second
 Guardian: ~500 files/second (Node.js)
 ```
 ✅ **Simplicity**
 ```bash
 # FTA does one thing well: metrics
 fta src/
 ```
 ### When Guardian Wins
 ✅ **Architecture enforcement**
 ```typescript
 // Guardian checks:
 // - Layer violations
 // - Framework leaks
 // - Circular dependencies
 // - Repository pattern
 // FTA: Only measures complexity, no architecture checks
 ```
 ✅ **Hardcode detection**
 ```typescript
 // Guardian finds magic numbers/strings
 // FTA doesn't check this
 ```
 ✅ **AI workflow**
 ```bash
 # Guardian provides actionable suggestions
 # FTA provides metrics only
 ```
 ### Complementary Usage
 **Best approach:** Use both!
 ```bash
 # Guardian for architecture
 guardian check ./src
 # FTA for complexity metrics
 fta src/ --threshold complexity:15
 ```
 **Coming in Guardian v0.10.0:**
 ```bash
 # Guardian will include complexity metrics!
 guardian metrics ./src --include-complexity
 ```
 ---
 ## vs ESLint + Plugins
 ### When ESLint Wins
 ✅ **General code quality**
 ```javascript
 // Best for:
 // - Code style
 // - Common bugs
 // - TypeScript errors
 // - React/Vue specific rules
 ```
 ✅ **Huge ecosystem**
 ```bash
 # 10,000+ plugins
 eslint-plugin-react
 eslint-plugin-vue
 eslint-plugin-security
 # ...and many more
 ```
 ✅ **Auto-fix for syntax**
 ```bash
 eslint --fix
 # Fixes semicolons, quotes, formatting, etc.
 ```
 ### When Guardian Wins
 ✅ **Architecture enforcement**
 ```typescript
 // ESLint doesn't understand:
 // - Clean Architecture layers
 // - DDD patterns
 // - Framework leaks
 // - Entity exposure
 // Guardian does!
 ```
 ✅ **Hardcode detection with context**
 ```typescript
 // ESLint plugins check patterns
 // Guardian understands semantic context
 ```
 ✅ **AI workflow integration**
 ```bash
 # Guardian optimized for AI assistants
 # ESLint generic output
 ```
 ### Complementary Usage
 **Best approach:** Use both!
 ```bash
 # ESLint for code quality
 eslint src/
 # Guardian for architecture
 guardian check ./src
 ```
 **Many teams run both in CI:**
 ```yaml
 # .github/workflows/quality.yml
 - name: ESLint
  run: npm run lint
 - name: Guardian
  run: guardian check ./src --fail-on error
 ```
 ---
 ## vs import-linter (Python)
 ### When import-linter Wins
 ✅ **Python projects**
 ```ini
 # .importlinter
 [importlinter]
 root_package = myproject
 [importlinter:contract:1]
 name = Layers contract
 type = layers
 layers =
    myproject.domain
    myproject.application
    myproject.infrastructure
 ```
 ✅ **Mature Python ecosystem**
 ```python
 # Django, Flask, FastAPI integration
 ```
 ### When Guardian Wins
 ✅ **TypeScript/JavaScript**
 ```typescript
 // Guardian is for TS/JS
 // import-linter is Python-only
 ```
 ✅ **More than import checking**
 ```typescript
 // Guardian checks:
 // - Hardcode
 // - Entity exposure
 // - Repository pattern
 // - Framework leaks
 // import-linter: Only imports
 ```
 ### Future Integration
 **Guardian v2.0+ (Planned):**
 ```bash
 # Multi-language support coming
 guardian check ./python-src --language python
 guardian check ./ts-src --language typescript
 ```

 **Why add Guardian:**
 ```typescript
 // ESLint checks syntax
 // Guardian checks architecture
 ```
 **How to add:**
 ```bash

 ### Version 0.8.0 - Secret Detection 🔐
 **Target:** Q1 2025
 **Priority:** CRITICAL
 Detect hardcoded secrets (API keys, tokens, credentials) using industry-standard Secretlint library.
 **🎯 SecretDetector - NEW standalone detector:**
 ```typescript
 // ❌ CRITICAL: Hardcoded AWS credentials
 const AWS_KEY = "AKIA1234567890ABCDEF"  // VIOLATION!
 const AWS_SECRET = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"  // VIOLATION!
 // ❌ CRITICAL: Hardcoded GitHub token
 const GITHUB_TOKEN = "ghp_1234567890abcdefghijklmnopqrstuv"  // VIOLATION!
 // ❌ CRITICAL: SSH Private Key in code
 const privateKey = `-----BEGIN RSA PRIVATE KEY-----
 MIIEpAIBAAKCAQEA...`  // VIOLATION!
 // ❌ CRITICAL: NPM token
 //registry.npmjs.org/:_authToken=npm_abc123xyz  // VIOLATION!
 // ✅ GOOD: Use environment variables
 const AWS_KEY = process.env.AWS_ACCESS_KEY_ID
 const AWS_SECRET = process.env.AWS_SECRET_ACCESS_KEY
 const GITHUB_TOKEN = process.env.GITHUB_TOKEN
 ```
 **Planned Features:**
 - ✅ **SecretDetector** - Standalone detector (separate from HardcodeDetector)
 - ✅ **Secretlint Integration** - Industry-standard library (@secretlint/node)
 - ✅ **350+ Secret Patterns** - AWS, GitHub, NPM, SSH, GCP, Slack, Basic Auth, etc.
 - ✅ **CRITICAL Severity** - All secret violations marked as critical
 - ✅ **Smart Suggestions** - Context-aware remediation per secret type
 - ✅ **Clean Architecture** - New ISecretDetector interface, SecretViolation value object
 - ✅ **CLI Integration** - New "🔐 Secrets" section in output
 - ✅ **Parallel Execution** - Runs alongside existing detectors
 **Secret Types Detected:**
 - AWS Access Keys & Secret Keys
 - GitHub Tokens (ghp_, github_pat_, gho_, etc.)
 - NPM tokens in .npmrc and code
 - SSH Private Keys
 - GCP Service Account credentials
 - Slack tokens (xoxb-, xoxp-, etc.)
 - Basic Auth credentials
 - JWT tokens
 - Private encryption keys
 **Architecture:**
 ```typescript
 // New domain layer
 interface ISecretDetector {
    detectAll(code: string, filePath: string): Promise<SecretViolation[]>
 }
 class SecretViolation {
    file: string
    line: number
    secretType: string  // AWS, GitHub, NPM, etc.
    message: string
    severity: "critical"
    suggestion: string  // Context-aware guidance
 }
 // New infrastructure implementation
 class SecretDetector implements ISecretDetector {
    // Uses @secretlint/node internally
 }
 ```
 **Why Secretlint?**
 - ✅ Actively maintained (updates weekly)
 - ✅ TypeScript native
 - ✅ Pluggable architecture
 - ✅ Low false positives
 - ✅ Industry standard
 **Why NOT custom implementation?**
 - ❌ No good npm library for magic numbers/strings
 - ❌ Our HardcodeDetector is better than existing solutions
 - ✅ Secretlint is perfect for secrets (don't reinvent the wheel)
 - ✅ Two focused detectors better than one bloated detector
 **Impact:**
 Guardian will now catch critical security issues BEFORE they reach production, complementing existing magic number/string detection.

 ## 📅 Detailed Roadmap
 ## Version 0.6.0 - Configuration & Presets ⚙️
 **Target:** Q1 2026 (January-February)
 **Priority:** 🔥 CRITICAL
 > **Why Critical:** All competitors (SonarQube, ESLint, dependency-cruiser) have configuration. Without this, Guardian cannot be customized for different teams/projects.
 ### Features
 #### 1. Configuration File Support
 ```javascript
 // guardian.config.js (primary)
 export default {
    // Zero-config presets
    preset: 'clean-architecture',  // or 'ddd', 'hexagonal', 'onion'
    // Rule configuration
    rules: {
        'hardcode/magic-numbers': 'error',
        'hardcode/magic-strings': 'warn',
        'architecture/layer-violation': 'error',
        'architecture/framework-leak': 'error',
        'architecture/entity-exposure': 'error',
        'circular-dependency': 'error',
        'naming-convention': 'warn',
        'dependency-direction': 'error',
        'repository-pattern': 'error',
    },
    // Custom layer paths
    layers: {
        domain: 'src/core/domain',
        application: 'src/core/application',
        infrastructure: 'src/adapters',
        shared: 'src/shared',
    },
    // Exclusions
    exclude: [
        '**/*.test.ts',
        '**/*.spec.ts',
        'scripts/',
        'migrations/',
        'node_modules/',
    ],
    // Per-rule ignores
    ignore: {
        'hardcode/magic-numbers': {
            'src/config/constants.ts': [3000, 8080],
        },
    },
 }
 ```
 #### 2. Built-in Presets
 ```javascript
 // Preset: clean-architecture (default)
 preset: 'clean-architecture'
 // Enables: layer-violation, dependency-direction, naming-convention
 // Preset: ddd
 preset: 'ddd'
 // Enables all DDD patterns: aggregates, value-objects, domain-events
 // Preset: hexagonal (Ports & Adapters)
 preset: 'hexagonal'
 // Validates port/adapter separation
 // Preset: minimal (for prototyping)
 preset: 'minimal'
 // Only critical rules: hardcode, circular-deps
 ```
 #### 3. Framework-Specific Presets
 ```javascript
 // NestJS
 preset: 'nestjs-clean-architecture'
 // Express
 preset: 'express-clean-architecture'
 // Next.js
 preset: 'nextjs-clean-architecture'
 ```
 #### 4. Configuration Discovery
 Support multiple config file formats:
 - `guardian.config.js` (ES modules)
 - `guardian.config.cjs` (CommonJS)
 - `.guardianrc` (JSON)
 - `.guardianrc.json`
 - `package.json` (`guardian` field)
 #### 5. CLI Override
 ```bash
 # Override config from CLI
 guardian check ./src --rule hardcode/magic-numbers=off
 # Use specific config file
 guardian check ./src --config custom-config.js
 # Generate config
 guardian init --preset clean-architecture
 ```
 ### Implementation Tasks
 - [ ] Create config parser and validator
 - [ ] Implement preset system
 - [ ] Add config discovery logic
 - [ ] Update AnalyzeProject use case to accept config
 - [ ] CLI integration for config override
 - [ ] Add `guardian init` command

 ## Version 0.9.0 - Auto-Fix & Code Generation 🤖
 **Target:** Q2 2026 (May)
 **Priority:** 🚀 GAME-CHANGER (UNIQUE!)
 > **Why Game-Changer:** No competitor has intelligent auto-fix for architecture. This makes Guardian unique!
 ### Features
 #### 1. Auto-Fix Hardcode
 ```bash
 # Fix all hardcode violations automatically
 guardian fix ./src --auto
 # Preview changes
 guardian fix ./src --dry-run
 # Fix specific types
 guardian fix ./src --type hardcode
 guardian fix ./src --type naming
 ```
 **Example:**
 ```typescript
 // Before
 const timeout = 5000
 app.listen(3000)
 // After (auto-generated constants.ts)
 export const DEFAULT_TIMEOUT_MS = 5000
 export const DEFAULT_PORT = 3000
 // After (fixed code)
 import { DEFAULT_TIMEOUT_MS, DEFAULT_PORT } from './constants'
 const timeout = DEFAULT_TIMEOUT_MS
 app.listen(DEFAULT_PORT)
 ```
 #### 2. Generate Constants File
 ```bash
 # Extract all hardcodes to constants
 guardian generate constants ./src --output src/config/constants.ts
 # Generated file:
 // src/config/constants.ts
 export const DEFAULT_TIMEOUT_MS = 5000
 export const DEFAULT_PORT = 3000
 export const MAX_RETRIES = 3
 export const API_BASE_URL = 'http://localhost:8080'
 ```
 #### 3. Fix Naming Violations
 ```bash
 # Rename files to match conventions
 guardian fix naming ./src --auto
 # Before: src/application/use-cases/user.ts
 # After:  src/application/use-cases/CreateUser.ts
 ```
 #### 4. AI-Friendly Fix Prompts
 ```bash
 # Generate prompt for AI assistant
 guardian check ./src --format ai-prompt > fix-prompt.txt
 # Output (optimized for Claude/GPT):
 """
 Fix the following Guardian violations:
 1. HARDCODE (src/api/server.ts:15)
   - Replace: app.listen(3000)
   - With: Extract 3000 to DEFAULT_PORT constant
   - Location: Create src/config/constants.ts
 2. FRAMEWORK_LEAK (src/domain/User.ts:5)
   - Remove: import { Request } from 'express'
   - Reason: Domain layer cannot import frameworks
   - Suggestion: Use dependency injection via interfaces
 [Complete fix suggestions...]
 """
 # Then feed to Claude:
 # cat fix-prompt.txt | pbcopy
 # Paste into Claude: "Fix these Guardian violations"
 ```
 #### 5. Interactive Fix Mode
 ```bash
 # Interactive fix selection
 guardian fix ./src --interactive
 # Prompts:
 # ? Fix hardcode in server.ts:15 (3000)? (Y/n)
 # ? Suggested constant name: DEFAULT_PORT
 #   [Edit name] [Skip] [Fix All]
 ```
 #### 6. Refactoring Commands
 ```bash
 # Break circular dependency
 guardian refactor circular ./src/services/UserService.ts
 # Suggests: Extract shared interface
 # Fix layer violation
 guardian refactor layer ./src/domain/entities/User.ts
 # Suggests: Move framework imports to infrastructure
 ```

 * - Aggregates should reference each other only by ID or Value Objects
 * - Direct entity references across aggregates create tight coupling
 * - Each aggregate should be independently modifiable
 *
 * Folder structure patterns detected:
 * - domain/aggregates/order/Order.ts
 * - domain/order/Order.ts (aggregate name from parent folder)
 * - domain/entities/order/Order.ts
 *
 * @example
 * ```typescript
 * const detector = new AggregateBoundaryDetector()
 *
 * // Detect violations in order aggregate
 * const code = `
 * import { User } from '../user/User'
 * import { UserId } from '../user/value-objects/UserId'
 * `
 * const violations = detector.detectViolations(
 *     code,
 *     'src/domain/aggregates/order/Order.ts',
 *     'domain'
 * )
 *
 * // violations will contain 1 violation for direct User entity import
 * // but not for UserId (value object is allowed)
 * console.log(violations.length) // 1
 * ```
