"700 Main Street" lud "777 Main Street" eines fremden Artists: buildTitleKeywords
behielt nur die zwei laengsten Woerter (Street, Main), die unterscheidende 700
fiel als zu kurz raus — und Schritt 3 der Kaskade prueft den Kuenstler-Channel
nicht mehr. Zahlen werden jetzt immer als \b<n>\b gefordert. Dazu eine kleine
Abkuerzungstabelle (street/st, saint/st, mount/mt, doctor/dr, versus/vs,
number/no), denn der korrekte Art Track heisst "700 Main st" und scheiterte
bisher an jedem Schritt. Tests in backend/test/ytdlp.test.js.

findExistingTrack split the filename at the first ' - ' assuming 'Artist - Title',
so a title with internal dashes ('Kingdom Hearts 2 - Dearly Beloved - Main Theme')
or a garbage/absent artist prefix ('01-01 - …') was mis-parsed → the duplicate went
undetected and got re-downloaded (3-4x). Now match the query title against BOTH the
full stem AND the part after the first ' - ', so titles with dashes and prefix-only
filenames are recognized. Normal 'Artist - Title' files still match; no false
positives; remix-vs-base distinction preserved. Unit-tested on the exact KH case.

Root cause: deezer pickTrackMatch fell back to a blind title-only match, grabbing a
same-titled song by a completely different artist (e.g. 'Memories' by Rab Noakes for
'☆NoAki☆') and applying its album/cover/year. The download's clean fallback existed
but was never reached because the lookup almost always returned *something*.
Stufe A — deezer.js: the title-only fallback now REQUIRES an artist correspondence
(equal, or one name contained in the other after normalization). No match → {} →
the existing clean fallback finally runs (album_artist = song artist, album =
'Singles', cover = source thumbnail, year/genre untouched). Test that encoded the old
blind behaviour replaced; NoAki + loose-match regression tests added.
Stufe B — musicbrainz.js: a rate-limited (~1/s, User-Agent) MusicBrainz recording
lookup with the SAME artist discipline + Cover Art Archive cover. trackmeta.js is the
single resolver (Deezer → MusicBrainz → clean fallback); the three single-track call
sites use it (album batch stays Deezer-only to avoid MB rate-limit slowdowns).
Unit-tested (17/17) + live-verified: NoAki→clean fallback, real track→Deezer, MB finds
real albums when Deezer misses. Backend-only; no frontend/Android change.

Apple's iTunes /search returns 403 from server/datacenter IPs, which had broken global
search, charts, album/artist/single downloads and the metadata-editor autofill in
production. Everything now sources metadata from Deezer (free, no key, more requests,
returns explicit versions + real artist images + durations). Web + Android share one
source, so an artist resolves to one consistent name everywhere. Deezer results are
mapped to the legacy "ItunesItem" shape, so the UI + download flow are unchanged.
Backend:
- New backend/lib/deezer.js: lookupTrackMeta, fetchAlbumTracks, searchAlbumTracks,
fetchArtistAlbums (+ pure pickTrackMatch/mapAlbumTrack for tests).
- metadata.js drops the iTunes lookups; novasonic-server download paths (track, album,
artist, playlist enrich, spotify artwork) + autofill now use Deezer.
- Artist download uses Deezer discography (real albums only), not the iTunes album search.
- Editor autofill endpoint /api/itunes/lookup -> /api/meta/lookup; removed the dead
iTunes /search proxy and the Apple charts RSS proxy.
- backend/test/deezer.test.js: unit tests for numbering, mixed-artist album-artist
stability, explicit flags, the Japanese-title match guard (npm test; RUN_LIVE=1 for live).
Web:
- api.js search/lookups already on Deezer; charts now use Deezer /chart. Artist cards
show the real Deezer photo. Visible "iTunes"/"Apple Music" labels -> "Deezer"
(search badge, charts badge, preview bar, editor button, artist heading). SW ns-v51.
Android:
- New DeezerModels.kt with Dz* models + mappers to ItunesItem/ItunesRssEntry.
- ItunesClient is Deezer-backed (search = tracks+albums+artists in parallel; album/artist
lookups; /chart charts), same method signatures. Visible strings -> Deezer.
Docs: README, CLAUDE.md and CHANGELOG (1.3) updated; Platform Parity Matrix reflects the
shared Deezer source + Android non-local artist page.
