September 2025 performance summary across LabKey/platform, LabKey/labkey-ui-components, and LabKey/testAutomation focused on data integrity, UI reliability, and developer velocity. Key features and structural improvements included refactoring API validation actions to ReadOnlyApiAction with a unique URI to enforce read-only semantics; substantial UI and data-model enhancements for sample amounts and units, enabling correct bulk updates and unit-based filtering; centralization of InventoryMetricUnit to a shared location for reuse across modules; and targeted test/infrastructure work to improve data handling and test reliability. Major bug fixes addressed build stability and data validation: resolving a merge-conflict-induced build break in EhSimpleCache and enforcing strict validation to reject non-finite doubles (Infinity/NaN) in API responses and conversions; plus a UI-level fix to preserve non-finite numeric values during input. Overall, these changes improve data quality, error reporting, and user experience, while reducing regression risk and enabling consistent behavior across platforms and apps.
