## Detailed Implementation Notes

### Completion of AstItem/NodeKind Alignment

The AstItem/NodeKind alignment task has been successfully completed, addressing the core issue in the polyglot AST framework. The implementation ensures that:

1. All variants of AstItem have a corresponding NodeKind representation
2. The conversion functions properly handle all item types
3. FQN generation is more accurate based on item type and context
4. Tests have been added to verify the alignment works correctly

In addition, we identified and fixed an issue with the HashSet import in the cross-language dependencies module, which was causing compilation errors.

### Completion of Feature Flag Implementation

The feature flag implementation has been completed, providing a modular way to include language support:

1. Added the `polyglot-ast` meta-feature in Cargo.toml
2. Implemented language-specific features that depend on the meta-feature
3. Updated language mapper factory to use conditional compilation
4. Created comprehensive documentation for feature flag usage

We also implemented language-specific modules for TypeScript and JavaScript to ensure the system works correctly with feature flags. All language mappers now support the `clone_box` method, ensuring consistent behavior across the system.

### Completion of StubMapper Implementation

The StubMapper implementation has been completed, providing fallback functionality for unsupported languages:

1. Added the StubMapper struct with complete LanguageMapper trait implementation
2. Added the clone_box method to all language mappers
3. Added the create_test_node method to simplify unit testing
4. Updated language mapper factory to use StubMapper for unsupported languages

### Next Steps: Language Mapper Updates

The next high-priority task is updating the individual language mappers for Java, Kotlin, and Scala:

1. Update the Java language mapper with full NodeKind support
2. Enhance the Kotlin language mapper with proper error handling
3. Update the Scala language mapper to handle all NodeKind variants
4. Add comprehensive tests for all language mappers

This task should begin with identifying the common patterns across language mappers and implementing them consistently.
