- Settings: 'Playlists Folder' path field (Unlock pattern, separate-root help
text), a Symlinks/Copies selector, and a 'Rebuild playlist folders now' button
(standard test-button style). Wired through PATH_INPUT_IDS / load / save, plus
'playlists' added to the settings save allowlist so it persists.
- POST /api/playlists/materialize/rebuild → rebuild_organized_playlists_from_db:
rebuilds every organize-by-playlist folder from CURRENT ownership, re-matching
each track with check_track_exists (name, not IDs) so it self-heals after a
reorganize / membership change. +1 test.
70 materialize tests + JS integrity pass; settings round-trip wiring verified.
materialize_playlist_from_batch(batch, download_tasks, config) collects the real
on-disk path of every resolved track from the batch's OWN payload — owned via
analysis_results.matched_file_path, downloaded via tasks.final_file_path — runs
each through the playback path resolver (Docker-correct), de-dupes, and hands the
list to rebuild_playlist_folder. Gated on playlist_folder_mode.
No re-matching, no source IDs, no mirrored-playlist lookup — works for any
organize-by-playlist download including the all-owned case. 5 tests. Still
isolated; the triggers wire it in next.
