- clients/omdb.py: OMDb als zweite Quelle (Fallback-Kette: TMDB exakt ->
OMDb -> bester TMDB-Vorschlag mit niedriger Confidence -> unknown)
- Pre-Scan-Reparatur: Titel kam nie an — makemkvcon existiert nur im
Worker, isosize war nirgends installiert (fiel still auf "DVD" zurueck).
Jetzt: ISO-9660-Volume-Label direkt vom Medium + Label-Normalisierung
(PULP_FICTION -> Pulp Fiction), Disc-Typ ueber zentrale detection.py
- POST /devices/{name}/eject (CDROMEJECT-ioctl) mit Job-Schutz (409 wenn
auf dem Laufwerk gerade gerippt wird)
- OMDB_API_KEY in compose/.env.example; .env.example komplett ehrlich
dokumentiert (JWT-Pflicht, MakeMKV-Beta-Key-Rhythmus)
