[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

New DDD feature to enforce aggregate boundaries and prevent tight coupling between aggregates.

✅ Aggregate Boundary Detector:
- Detects direct entity references across aggregate boundaries
- Validates that aggregates reference each other only by ID or Value Objects
- Supports multiple folder structure patterns:
  - domain/aggregates/order/Order.ts
  - domain/order/Order.ts
  - domain/entities/order/Order.ts
✅ Smart Import Analysis:
- Parses ES6 imports and CommonJS require statements
- Identifies entity imports from other aggregates
- Allows imports from value-objects, events, services, specifications folders
✅ Actionable Suggestions:
- Reference by ID instead of entity
- Use Value Objects to store needed data from other aggregates
- Maintain aggregate independence
✅ CLI Integration:
- --architecture flag includes aggregate boundary checks
- CRITICAL severity for violations
- Detailed violation messages with file:line references
✅ Test Coverage:

[0.6.4] - 2025-11-24

Added

🎯 Smart Context-Aware Suggestions for Repository Method Names

Guardian now provides intelligent, context-specific suggestions when it detects non-domain method names in repositories.

✅ Intelligent method name analysis:
- queryUsers() → Suggests: search, findBy[Property]
- selectById() → Suggests: findBy[Property], get[Entity]
- insertUser() → Suggests: create, add[Entity], store[Entity]
- updateRecord() → Suggests: update, modify[Entity]
- upsertUser() → Suggests: save, store[Entity]
- removeUser() → Suggests: delete, removeBy[Property]
- fetchUserData() → Suggests: findBy[Property], get[Entity]
- And more technical patterns detected automatically!
🎯 Impact:
- Developers get actionable, relevant suggestions instead of generic examples
- Faster refactoring with specific naming alternatives
- Better learning experience for developers new to DDD

Fixed

✅ Expanded domain method patterns support:
- find*() methods - e.g., findNodes(), findNodeById(), findSimilar()
- saveAll() - batch save operations
- deleteBy*() methods - e.g., deleteByPath(), deleteById()
- deleteAll() - clear all entities
- add*() methods - e.g., addRelationship(), addItem()
- initializeCollection() - collection initialization
🐛 Removed findAll from technical methods blacklist:
- findAll() is now correctly recognized as a standard domain method
- Reduced false positives for repositories using this common pattern

Technical

Added suggestDomainMethodName() method in RepositoryPatternDetector.ts with keyword-based suggestion mapping
Updated getNonDomainMethodSuggestion() in RepositoryViolation.ts to extract and use smart suggestions
Refactored suggestion logic to reduce cyclomatic complexity (22 → 9)
Enhanced domainMethodPatterns with 9 additional patterns
All 333 tests passing

[0.6.3] - 2025-11-24

Fixed

🐛 Repository Pattern Detection - Reduced False Positives

Fixed overly strict repository method name validation that was flagging valid DDD patterns as violations.

✅ Added support for common DDD repository patterns:
- has*() methods - e.g., hasProject(), hasPermission()
- is*() methods - e.g., isCached(), isActive()
- exists*() methods - e.g., existsById(), existsByEmail()
- clear*() methods - e.g., clearCache(), clearAll()
- store*() methods - e.g., storeMetadata(), storeFile()
- Lifecycle methods: initialize(), close(), connect(), disconnect()
🎯 Impact:
- Reduced false positives in real-world DDD projects
- Better alignment with Domain-Driven Design best practices
- More practical for cache repositories, connection management, and business queries
📚 Why these patterns are valid:
- Martin Fowler's Repository Pattern allows domain-specific query methods
- DDD recommends using ubiquitous language in method names
- Lifecycle methods are standard for resource management in repositories

Technical

Updated domainMethodPatterns in RepositoryPatternDetector.ts with 11 additional valid patterns
All existing functionality remains unchanged
