Valerie Gleason enhanced the ni/nitypes-python repository by delivering two user-facing features focused on improving API consistency and data integrity. She standardized unit terminology across NumericWaveform and Spectrum, updating property names, setters, and error messages to ensure clarity and maintainability. Valerie also introduced a sample_count setter for DigitalWaveform and NumericWaveform, implementing capacity validation to prevent configuration errors and adding comprehensive unit tests for both normal and edge cases. Working primarily in Python, she emphasized code consistency and robust refactoring, resulting in improved reliability for downstream users and a more accessible codebase for future contributors and maintainers.
