### 3.2 Eliminate Code Duplication
**Status**: NOT STARTED
**Target duplications**:
- Movie DB pattern extraction (44 lines duplicated)
- Frame class matching (duplicated logic)
- Year extraction (duplicated logic)
### 3.2 Eliminate Code Duplication ✅ COMPLETED
**Status**: COMPLETED
**Completed**: 2025-12-31
**Note**: Language code detection duplication (~150 lines) was eliminated in Phase 3.1
**What was done**:
1. **Eliminated Movie DB pattern extraction duplication**
- Refactored `extract_movie_db()` in filename_extractor.py
- Now uses `PatternExtractor.extract_movie_db_ids()` utility (created in Phase 2.4)
- Removed 15 lines of duplicated pattern matching code
- File reduced from 486 → 477 lines (-9 lines, 1.9%)
2. **Leveraged existing utilities from Phase 2.4**
- `PatternExtractor` utility already created with movie DB, year, and quality extraction
- `LanguageCodeExtractor` utility already used (Phase 3.1)
- `FrameClassMatcher` utility available for future use
**Benefits**:
- Eliminated code duplication between filename_extractor and pattern_utils
- Single source of truth for movie DB ID extraction logic
- Easier to maintain and test pattern matching
- Consistent behavior across codebase
**Test Status**: All 559 tests passing ✅
**Files Modified (1)**:
- `renamer/extractors/filename_extractor.py` - Uses PatternExtractor utility
**Code Reduction**:
- 15 lines of duplicated regex/pattern matching code removed
- FilenameExtractor now delegates to utility for movie DB extraction
**Notes**:
- Frame class matching and year extraction reviewed
- Year extraction in filename_extractor has additional dot-pattern (`.2020.`) not in utility
- Frame class utilities available but filename_extractor logic is more specialized
- Language code duplication already eliminated in Phase 3.1

### 3.4 Add Missing Type Hints
**Status**: NOT STARTED
**Files needing type hints**:
- `renamer/extractors/default_extractor.py` (13 methods)
- Various cache methods (replace `Any` with specific types)
### 3.4 Add Missing Type Hints ✅ COMPLETED
**Status**: COMPLETED
**Completed**: 2025-12-31
**What was done**:
1. **Added type hints to default_extractor.py**
- Added `from typing import Optional` import
- Added return type hints to all 21 methods
- Types: `Optional[str]`, `Optional[int]`, `Optional[float]`, `list[dict]`, `list[str] | None`
- All methods now conform to DataExtractor Protocol signatures
2. **Reviewed cache type hints**
- Verified all uses of `Any` in cache subsystem
- Determined that `Any` is appropriate for:
- `CacheEntry.value: Any` - stores any JSON-serializable type
- `instance: Any` in decorators - can decorate any class
- `Cache.set(value: Any)` - can cache any type
- No changes needed - existing type hints are correct
3. **Added mypy as dev dependency**
- Added `[project.optional-dependencies]` section to pyproject.toml
- Added `mypy>=1.0.0` to dev dependencies
- Ran `uv sync --extra dev` to install mypy
4. **Verified with mypy**
- Ran mypy on default_extractor.py
- Zero type errors found in default_extractor.py
- All type hints conform to Protocol signatures from base.py
**Benefits**:
- Complete type coverage for DefaultExtractor class
- Improved IDE autocomplete and type checking
- Protocol conformance verified by mypy
- Mypy now available for future type checking
**Test Status**: All 559 tests passing ✅
**Files Modified (2)**:
- `renamer/extractors/default_extractor.py` - Added type hints to all 21 methods
- `pyproject.toml` - Added mypy to dev dependencies
**Mypy Verification**:
```
uv run mypy renamer/extractors/default_extractor.py
# Result: 0 errors in default_extractor.py
```

### 3.5 Add Comprehensive Docstrings
**Status**: NOT STARTED
**All modules need docstring review**
### 3.5 Add Comprehensive Docstrings ✅ COMPLETED
**Status**: COMPLETED
**Completed**: 2026-01-01
**What was done**:
1. **Added comprehensive docstrings to key extractor modules**
- `default_extractor.py`: Module docstring + class docstring + 21 method docstrings
- `extractor.py`: Module docstring + enhanced class docstring + method docstrings
- `fileinfo_extractor.py`: Module docstring + enhanced class docstring + method docstrings
- `metadata_extractor.py`: Module docstring + enhanced class docstring + method docstrings
2. **Added comprehensive docstrings to formatter module**
- `formatter.py`: Module docstring + class docstring + method docstrings
- Enhanced `FormatterApplier.apply_formatters()` with detailed Args/Returns
- Enhanced `FormatterApplier.format_data_item()` with examples
3. **Verified all module-level docstrings**
- All services modules have docstrings (file_tree_service, metadata_service, rename_service)
- All utils modules have docstrings (language_utils, pattern_utils, frame_utils)
- All constants modules have docstrings (8 modules)
- Base classes and protocols already documented (Phase 2)
**Docstring Standards Applied**:
- Module-level docstrings explaining purpose
- Class docstrings with Attributes and Examples
- Method docstrings with Args, Returns, and Examples
- Google-style docstring format
- Clear, concise descriptions
**Benefits**:
- Improved code documentation for all major modules
- Better IDE tooltips and autocomplete information
- Easier onboarding for new developers
- Clear API documentation with examples
- Professional code quality standards
**Test Status**: All 559 tests passing ✅
**Files Modified (5)**:
- `renamer/extractors/default_extractor.py` - Added module + 22 docstrings
- `renamer/extractors/extractor.py` - Added module + enhanced docstrings
- `renamer/extractors/fileinfo_extractor.py` - Added module + enhanced docstrings
- `renamer/extractors/metadata_extractor.py` - Added module + enhanced docstrings
- `renamer/formatters/formatter.py` - Added module + enhanced docstrings
**Coverage**:
- 5 files enhanced with comprehensive docstrings
- All key extractors documented
- FormatterApplier fully documented
- All existing Phase 2 modules already had docstrings
