Nov 1, 2024November 2024 RUFaS monthly summary: Configuration and test-data quality improvements focused on reliability and readiness for parameter tuning. Implemented configuration metadata refinements to default_animal.json and default.json, tightening metadata and inputs while preserving end-user behavior. Enhanced test data realism by adjusting parity fractions across test inputs, improving coverage for realistic herd compositions. These changes reduce configuration drift, increase test fidelity, and lay a stronger foundation for future parameter tuning and feature work.
