gallery_service._provenance_clause artist branch was correlating its bare Post reference to the outer query's primary_post_id outer-join, so the artist filter silently matched zero rows for images with no primary post. Alias Post inside the EXISTS subquery so SQLAlchemy adds it to the inner FROM rather than treating it as a correlated outer table. Five sidecar/import tests still asserted that a synthetic Source row appears after a filesystem import. Alembic 0030 retired that behavior; the Post sits null-source and the artist linkage lives on Post.artist_id. Updated test_sidecar_creates_provenance, test_reimport_same_post_idempotent, test_sidecar_artist_used_when_no_folder_artist, test_supersede_applies_new_file_sidecar, and test_apply_sidecar_recovers_from_integrity_error to assert post.source_id IS NULL + post.artist_id linkage instead.
