April 2025 monthly summary focused on delivering core data layer improvements, robust data ingestion, and architectural enhancements across two repositories. Key efforts included a CSV parsing overhaul, the introduction of domain models and a meals data access layer, and a major UI/Use Case Architecture refactor with dependency injection to improve maintainability and testability. Task 6 was implemented and merged with Task 12 under FP principles, with constraints for the 'shown before sweets' rule. Expanded testing, CI infrastructure, and tooling (Jacoco) to raise quality and confidence. Plan-mate progressed with scaffolding, password hashing extensions, and CI/testing utilities. Critical bugs were addressed, including no-egg sweets use case bug, Italian meals DI wiring, merge issue fixes, and in-memory data integrity improvements. Overall impact: faster, more reliable data processing; safer password handling; clearer separation of concerns; and a solid foundation for scalable feature work.
