The dashboard's enrichment-status bubbles (MusicBrainz, AudioDB,
Discogs, Deezer, Spotify, iTunes, Last.fm, Genius, Tidal, Qobuz) each
had its own copy-pasted /status, /pause, /resume route in web_server.py
— 30 routes that differed only in the worker reference and a couple
of per-service quirks (Spotify's rate-limit guard, Last.fm/Genius
yield-override behavior, Tidal/Qobuz extra status fields).
Replace them with a registry-driven blueprint:
- core/enrichment/services.py declares an EnrichmentService dataclass
with worker_getter, config_paused_key, pre_resume_check,
auto_pause_token, and extra_status_defaults — all variation captured
as data, no branching on service id.
- core/enrichment/api.py exposes a Flask blueprint with three routes
(/api/enrichment/<service>/{status,pause,resume}). Per-service
quirks are honored via the descriptor: Spotify's rate-limit ban
still returns 429 with `rate_limited: true`, Last.fm/Genius still
drop the auto-pause token and add the yield override, Tidal/Qobuz
still merge `authenticated: false` into the fallback payload.
- web_server.py registers all 10 services after their workers
initialize, wires the host-side hooks (config_manager.set,
_download_auto_paused.discard, _download_yield_override.add), and
registers the blueprint.
- webui/static/enrichment.js polling + click handlers now hit the
generic endpoints. The per-service `update<Service>StatusFromData`
functions are unchanged — they still process the same payload.
This is the cutover step. Old per-service routes are intentionally
left in place as a fallback during the soak period — they currently
have zero callers in the codebase and will be deleted in a follow-up
patch once production has run on the new pipeline for a few days.
27 new tests in tests/test_enrichment_services.py cover the registry
behavior + every quirk path through the generic blueprint (rate-limit
guard, auto-pause token cleanup, persisted-pause config keys, extra
default fields, worker-not-initialized fallback, exceptions). Full
suite 1541 passed; ruff clean.
