slugify() produces ASCII-only lowercase slugs from arbitrary text (used for artist slugs and tag slugs). paths.derive_subdir/derive_top_level_artist extract the destination layout and folder→artist convention from an import source path. hash_suffixed_name builds IR-style 'stem__hash10.ext' filenames.
