October 2025 monthly summary: Focused on stabilizing seed data, enhancing maintainability, and codifying architectural decisions. In dtos-manage-breast-screening: fixed case-sensitive seed data for symptom types causing seed command failures; implemented infrastructure naming consistency and environment updates including Terraform rename to enable_entra_id_authentication and Node.js upgrade to 22.20.0, plus container variable naming alignment; documented architectural decisions for audit logging and user attribution (ADR-004/ADR-005). In dtos-devops-templates: clarified authentication naming by renaming enable_auth to enable_entra_id_authentication to improve clarity in code and docs. Overall, these changes reduce data and deployment risks, improve maintainability, and provide a governance trail for security and immutable state decisions.
