August 2025 monthly summary focusing on the delivery-service repository. Primary delivery this month was a refactor of the BDBA scanning utilities, extracting the logic into a dedicated bdba_utils package to improve code organization and enable reuse across extensions. The core scanning functionality remains unchanged, with implementation details encapsulated in a reusable utility module. This work establishes a foundation for easier testing, extension integration, and cross-repo reuse.
