WHY IT NEEDS A POLICY

Why fix_media_match needs a policy

This tool modifies metadata by correcting an incorrect media match, which is a reversible data modification (re-matching can be undone or re-done). It falls under Write as it updates how media is identified/matched in the library without irreversibly destroying data.
