Month 2024-10: Key deliveries focused on data loading configurability and code quality improvements in hmftools. Implemented Flexible and backward-compatible data loading configuration: decoupled data loading from fixed file naming, added base filename config, optional file name, and optional directory support, preserving backward compatibility with legacy tools. Completed code formatting cleanup in patient-db module (LoadLinxData and LoadSignatures) to improve readability and maintainability without changing behavior. These changes reduce technical debt, improve pipeline resilience, and enable smoother data workflows for downstream systems.
