Per Boulder's calls on the new enrichment toggle:
- Naming: "Spotify Free" was misleading (it's a hybrid — pick it, connect an
account, and sync still uses your official playlists). Relabel the user-facing
strings to "Spotify (no auth)" — the real distinction is needs-credentials vs
not. Internal value/key (spotify_free, _free_*) unchanged, so no migration.
- Default ON: metadata.spotify_free_enrichment now defaults True (worker + UI
load both treat unset as on). So bulk enrichment runs on the no-auth path by
default and the official account is reserved for interactive search/sync; turn
the toggle off to enrich through the connected account. The toggle overrides
auth for the worker (authed users still enrich via no-auth) — matching the
intended model.
- Worker runs on the toggle alone: is_spotify_metadata_available() now honors
_prefer_free (+ package installed), so the worker enriches via no-auth even
with no account connected and no 'no-auth' source selected. Only fires on a
client carrying the flag (the worker's own), so interactive/watchlist
availability is unchanged.
- UI: moved the toggle from "Metadata Source" to the Spotify section next to the
auth fields, always visible, on by default. Help notes the genre trade-off.
Tests: prefer_free makes metadata available without auth/source (and is inert
without the package); interactive availability unaffected. 218 Spotify tests pass.
