Apr 1, 2025April 2025: Delivered a targeted schema enhancement and migration for trial type categorization in brown-ccv/xma-portal. Implemented a new ENUM-based Trial.type column with a migration that initializes existing rows to 'DATA' and removes the default after completion to ensure future rows are explicitly set. This work improves data integrity, enables precise reporting, and supports future validation and analytics initiatives.
