March 2026: Delivered core data integrity improvements and modulation features across the calculator stack (service, API, and frontend). Implemented POM data filtering by obligated submitter, suppressed non-actionable Synapse warnings when no POM/NoL, introduced RAG-based late tonnage modulation across results and the cost builder, extended the API with modulation default parameters for materials and tonnage, and enhanced frontend visibility of modulation parameters. These changes improve data accuracy, reduce log noise, and provide clearer visibility into modulation factors for late reporting tonnage, aligning with business goals of reliable reporting and cost calculations.
