Worked on stabilizing PHP import resolution within the code-review-graph repository, focusing on improving dependency tracking accuracy for code reviews. Addressed a critical bug by enhancing the mapping of fully-qualified PHP names to absolute file paths, supporting complex scenarios such as aliases, grouped imports, and vendor fallbacks. Utilized AST parsing and dependency analysis techniques in PHP and Python to ensure robust handling of import statements. Introduced a comprehensive test suite to validate these improvements across edge cases, reinforcing reliability and reducing false positives in dependency graphs. Emphasized test-driven development and maintainable code changes to support long-term project stability.
