The Odesli/Songlink API rejects artist URLs (405 UNSUPPORTED_URL — it is song/album
only), so the planned Odesli hop is not viable for artist linking. Pivoted to
MusicBrainz `inc=url-rels`, which returns the artist's official Bandcamp + Spotify
URLs directly, zero-cred:
- service/lib.js: relUrls() extracts direct bandcamp/spotify from MB relations;
mbResult() prefers them, falls back to search URLs per-platform (replaces searchResult).
- service/resolver.js: viaMusicBrainz now does search -> url-rels enrichment (both
throttled through one gate); resolveOne calls it directly.
- service/lib.test.js: +3 tests (relUrls + mbResult); 9 total, green.
- README: document the direct-link behavior.
Verified zero-cred end to end: "Cattle Decapitation" -> open.spotify.com/artist/... +
cattledecapitation.bandcamp.com/ (both direct, not search); nonsense -> null.
Source: task/odesli-direct-links (objective/linker-improvements); approach changed from
Odesli to MB url-rels after the API probe; goal (direct Bandcamp) achieved.
