October 2025 performance summary for NHSDigital/dtos-manage-breast-screening. Delivered a robust appointment data ingestion enhancement by introducing handle_aliased_column to accurately retrieve data from aliased column names (e.g., 'Screen' vs 'Screen or Assess'). Updated create_appointments.py to gracefully handle missing aliases by returning None when neither alias exists and refactored access patterns to use dict.get for safer data retrieval.
