During October 2025, Eric Deutsch enhanced the RTXteam/RTX repository by implementing programmatic QPath support in ARAXQuery and ARAXMessenger, enabling more flexible graph construction and reliable query handling. He developed the add_qpath DSL command with subject and object QNode validation and automatic QPath key generation, ensuring robust integration into the QueryGraph. Eric also refactored PathfinderQueryGraph handling to preserve existing paths and introduced duplicate key detection, reducing the risk of errors in graph manipulation. His work leveraged Python, API development, and test-driven development practices, resulting in improved backend reliability and expanded test coverage for graph database operations within the project.
