Worked on LMS-Community/slimserver to implement a stop-gap data integrity safeguard addressing contributor MBID and artist name mismatches. Using Perl, the solution introduced defensive logic in the data pipeline to drop ambiguous MBIDs when the number of artist names and MBIDs did not align, thereby preventing incorrect contributor data bindings and preserving database quality. The change was localized to the Slim::Schema::Contributor::add method, with clear documentation for affected libraries requiring cache wipes. This approach emphasized data validation and database management while laying the groundwork for a comprehensive fix aligned with Picard tagging conventions and future schema improvements.
