Companion (main.py):
• NAVIDROME_TAGS whitelist — the single source of truth for what tags
survive
• enforce_tag_whitelist() — whitelist enforcer, replaces blacklist
approach
• All 5 write points updated: apply_tags, apply_tags_dict,
upload-track, upload-tracks, restructure_all
• preserve_composer and preserve_lyrics flags on both upload
endpoints (default False)
• /library/clean-tags now uses whitelist enforcer
iOS:
• UploadMetadata — preserveComposer and preserveLyrics fields
• buildMultipartBody — sends both flags as form fields
• BatchUploadView — two toggles, both off by default, wired end-to-end
• MultiAlbumEditorSheet — full rewrite matching
BatchAlbumEditorSheet: MusicBrainz search, swipe to exclude/include
tracks, Reset button, cover art widget with red glow
