In December 2024, Philipp Seitz modularized the detectors logic in the tqec/tqec repository by extracting circuit.detectors into a standalone Python package, tqecd. This refactoring effort focused on code organization and dependency management, updating requirements.txt and project documentation to reflect the new structure. By decoupling detectors from the core tqec module, Philipp improved maintainability and enabled easier reuse and testing across dependent services. The work emphasized clean separation of concerns and future extensibility, supporting faster feature delivery. Throughout the process, Philipp applied skills in refactoring and documentation updates, delivering a well-structured foundation for ongoing development in the Python ecosystem.
