+## Description
+
+`PruneAssets` worker (`lib/music_library/worker/prune_assets.ex:16-35`) builds Ecto queries and calls `Repo.delete_all` directly, violating the convention that workers are thin wrappers delegating to context modules. All other workers delegate to context functions. This logic should live in `MusicLibrary.Assets`.
+
+## Expected behavior
+
+Extract the query and deletion into an `Assets.prune_unreferenced/0` context function, and have the worker call it.

+## Found during

+Codebase consistency audit (2026-03-25)
