Elies Bertran focused on improving the stability of audit trigger management in the Giswater/giswater_dbmodel repository during the past month. He addressed a bug in the update_audit_triggers function by correcting trigger name concatenation and implementing logic to drop existing triggers before recreating them, which reduces the risk of misnamed or duplicate triggers. Additionally, he refined a SQL string literal to ensure robust trigger execution. Working primarily with SQL and database management, Elies prioritized correctness and maintainability over new feature development, delivering targeted improvements that enhance the reliability of the auditing workflow and reduce operational risk in core database functionality.
