Nov 1, 2025

In 2025-11 for the osunyorg/admin repository, delivered a focused improvement to localization data integrity by introducing a unique constraint to prevent duplicate localization records for the same content in a single language. Implemented a migration and related schema updates to enforce the constraint now and for future entries. This reduces data quality risks, improves reliability of localization queries and reporting, and supports scalable multi-language content delivery.
