## [0.7.0] - 2026-01-01
### Major Refactoring (Phases 1-3)
Significant refactoring focused on code quality, architecture, and maintainability.
---
### Phase 3: Code Quality (COMPLETED)
#### Added
- **Type Hints**: Complete type coverage for `DefaultExtractor` (21 methods)
- **Mypy Integration**: Added mypy>=1.0.0 as dev dependency for type checking
- **Comprehensive Docstrings**: Added module + class + method docstrings to 5 key files:
- `default_extractor.py` - 22 docstrings
- `extractor.py` - Enhanced with examples
- `fileinfo_extractor.py` - Enhanced with Args/Returns
- `metadata_extractor.py` - Enhanced with examples
- `formatter.py` - Enhanced FormatterApplier
#### Changed
- **Constants Reorganization**: Split monolithic `constants.py` into 8 logical modules:
- `media_constants.py` - Media types
- `source_constants.py` - Video sources
- `frame_constants.py` - Frame classes and quality indicators
- `moviedb_constants.py` - Database identifiers
- `edition_constants.py` - Special editions
- `lang_constants.py` - Skip words for language detection
- `year_constants.py` - Dynamic year validation
- `cyrillic_constants.py` - Character mappings
- **Dynamic Year Validation**: Replaced hardcoded year values with `is_valid_year()` function
- **Language Extraction**: Simplified using `langcodes.Language.get()` for dynamic validation (~80 lines removed)
#### Removed
- **Code Duplication**: Eliminated ~95 lines of duplicated code:
- ~80 lines of hardcoded language lists
- ~15 lines of duplicated movie DB pattern matching
- **Hardcoded Values**: Removed hardcoded quality indicators, year values, Cyrillic mappings
### Phase 2: Architecture Foundation (COMPLETED)
#### Added
- **Base Classes and Protocols** (409 lines):
- `DataExtractor` Protocol defining extractor interface (23 methods)
- `Formatter` ABCs: `DataFormatter`, `TextFormatter`, `MarkupFormatter`, `CompositeFormatter`
- **Service Layer** (935 lines):
- `FileTreeService`: Directory scanning and validation
- `MetadataService`: Thread-pooled metadata extraction with cancellation support
- `RenameService`: Filename validation, sanitization, and atomic renaming
- **Utility Modules** (953 lines):
- `PatternExtractor`: Centralized regex pattern matching
- `LanguageCodeExtractor`: Language code processing
- `FrameClassMatcher`: Resolution/frame class matching
- **Command Palette Integration**:
- `AppCommandProvider`: 11 main app commands (open, scan_local, scan, refresh, rename, convert, delete, toggle_mode, expand, settings, help)
- `CacheCommandProvider`: 7 cache management commands
- Access via Ctrl+P
#### Improved
- **Thread Safety**: MetadataService uses ThreadPoolExecutor with Lock for concurrent operations
- **Testability**: Services can be tested independently of UI
- **Reusability**: Clear interfaces and separation of concerns
### Phase 1: Critical Bug Fixes (COMPLETED)
#### Fixed
- **Cache Key Generation Bug**: Fixed critical variable scoping issue in cache system
- **Resource Leaks**: Fixed file handle leaks in tests (proper context managers)
- **Exception Handling**: Replaced bare `except:` clauses with specific exceptions
#### Added
- **Thread Safety**: Added `threading.RLock` to cache for concurrent access
- **Logging**: Comprehensive logging throughout extractors and formatters:
- Debug: Language code conversions, metadata reads
- Warning: Network failures, API errors, MediaInfo parse failures
- Error: Formatter application failures
#### Changed
- **Unified Cache Subsystem** (500 lines):
- Modular architecture: `core.py`, `types.py`, `strategies.py`, `managers.py`, `decorators.py`
- 4 cache key strategies: `FilepathMethodStrategy`, `APIRequestStrategy`, `SimpleKeyStrategy`, `CustomStrategy`
- Enhanced decorators: `@cached_method()`, `@cached_api()`, `@cached_property()`
- Cache manager operations: `clear_all()`, `clear_by_prefix()`, `clear_expired()`, `compact_cache()`
---
### Phase 5: Test Coverage (PARTIALLY COMPLETED - 4/6)
#### Added
- **Service Tests** (30+ tests): FileTreeService, MetadataService, RenameService
- **Utility Tests** (70+ tests): PatternExtractor, LanguageCodeExtractor, FrameClassMatcher
- **Formatter Tests** (40+ tests): All formatter classes and FormatterApplier
- **Cache Tests** (18 tests): Cache subsystem functionality
- **Dataset Organization**:
- `filename_patterns.json`: 46 comprehensive test cases
- `frame_class_tests.json`: 25 frame class test cases
- Sample file generator: `fill_sample_mediafiles.py`
- Dataset loaders in `conftest.py`
#### Changed
- **Test Organization**: Consolidated test data into `src/test/datasets/`
- **Total Tests**: 560 tests (1 skipped), all passing
---
### Documentation Improvements
#### Added
- **AGENTS.md**: Comprehensive 900+ line technical reference
- **CHANGELOG.md**: This file
#### Changed
- **CLAUDE.md**: Streamlined to pointer to AGENTS.md
- **AI_AGENT.md**: Marked as deprecated, points to AGENTS.md
- **DEVELOP.md**: Streamlined with references to AGENTS.md
- **README.md**: Streamlined user guide with references
#### Removed
- Outdated version information from documentation files
- Duplicated content now in AGENTS.md
---
### Breaking Changes
#### Cache System
- **Cache key format changed**: Old cache files are invalid
- **Migration**: Users should clear cache: `rm -rf ~/.cache/moma/`
- **Impact**: No data loss, just cache miss on first run after upgrade
#### Dependencies
- **Added**: mypy>=1.0.0 as dev dependency
---
### Statistics

- Phase 3: ~200 lines (docstrings)
- Phase 5: ~500 lines (new tests)
- **Lines Removed**: ~290 lines through code duplication elimination
- **Net Gain**: ~3,207 lines of quality code
#### Test Coverage
