Complete the tag editor with remote metadata auto-fill.
- qbz-integrations: add frontend-agnostic `discogs` (client + DTOs, Tauri-free)
and `remote_metadata` (unified DTOs + the pure MusicBrainz/Discogs ->
RemoteAlbum* converters). Copied from src-tauri so the Slint frontend can do
remote lookup without depending on the Tauri binary; src-tauri is left fully
untouched (the production build keeps its own copy — no Tauri-build risk).
- tag_editor.rs: search_remote (provider QbzSelect; MusicBrainzClient::new
search_releases_extended / DiscogsClient search_releases, generation-guarded),
select_result, apply_remote (get_release_with_tracks / get_release_metadata ->
full metadata; overwrites album fields + positional per-track title merge;
track-count-mismatch + rate-limit toasts), open_in_browser.
- TagEditorModal: a remote-lookup box (provider + Search, a horizontal result
card strip with select highlight, Apply + open-in-browser). ADR-008: square
badges, no pills.
- state.slint: RemoteResultItem struct + remote fields/actions on TagEditor*.
LocalLibrary Slint port is now feature-complete (scan/folders, artists images,
tag editor manual+remote, tracks bulk). BUILT BLIND — runtime smoke-test pending.

The Cloudflare proxy funnelled every user's MusicBrainz traffic onto a few
egress IPs, and MusicBrainz rate-limits 1 req/s per IP, so the budget was
shared across the whole userbase and produced 503s that worsen with growth.
MB read access needs no key and authentication does not raise the limit, so
the proxy added only the funnel; going per-IP makes the budget per-user.
- qbz-integrations MusicBrainzConfig default is now use_proxy=false (direct).
- client: handle HTTP 503 + Retry-After (not just 429, which the proxy used
to translate); add parse_retry_after; route search_recording_by_isrc and
search_artist through handle_response_status.
- src-tauri session_lifecycle: MusicBrainz V2 init/teardown pass use_proxy=false.
Slint inherits this via CoreBridge's default-constructed client.

Closes the network sidebar with the fifth section — tag-based "You may
also like" discovery, with a per-tag dismiss store so a thumbs-down
sticks across artist pages that share the same primary genre tag.
Backend (`qbz-integrations` + `qbz-core`):
- DiscoveryArtist and DiscoveryResponse DTOs added to
qbz-integrations::musicbrainz::models.
- QbzCore::musicbrainz_discover_artists ports
v2_get_discovery_artists end to end (sans the RecoState local
"play count > 2" filter, which has no equivalent in the Slint
shell yet): primary-tag search, exclude seed + similar +
dismissed, deterministic shuffle keyed on seed_mbid, validate
each candidate on Qobuz, fall back to the secondary tag if we
have fewer than 5 matches.
- normalize_artist_name re-exported at the qbz-core crate root so
the dismiss handler in qbz-slint can use the same key shape that
the discovery pipeline filters on.
- Deterministic shuffle implemented with a simple xorshift PRNG
seeded from a stable hash of seed_mbid — keeps qbz-core free of
the rand dep.
Slint controller (`crates/qbz-slint/src/`):
- discovery_dismiss.rs — small JSON store at
`<data-dir>/qbz/discovery_dismiss.json` keyed by lowercased tag
-> list of normalized artist names. dismissed_for_tag is passed
into the discovery call as the filter source; dismiss() is
invoked by the thumbs-down handler.
- artist::load_mb_discovery / apply_mb_discovery /
remove_discovery_artist plumb the pipeline result through the
standard load-off-thread / apply-on-UI split. Discovery state
includes primary_tag so the dismiss handler can persist under
the right key.
- main.rs chains discovery after relationships in the same MB
enrichment task. NetworkSidebarActions.discovery-dismissed (now
carrying mbid + name) normalizes the name, persists the
dismiss, and removes the row from the visible list.
Slint UI (`ui/state.slint`, `ui/artist/ArtistPageView.slint`):
- discovery-tag property added to NetworkSidebarState.
- YOU MAY ALSO LIKE section after Relationships — one row per
candidate (SidebarLink + a 24x24 thumbs-down button on the
right). Clicking the link navigates via the artist-clicked
callback when a Qobuz id is present.
- thumbs-down.svg icon added to ui/assets/icons (Lucide
ThumbsDown).

Pure-logic move of two helper modules out of src-tauri/src/musicbrainz/
into the qbz-integrations crate, where the MusicBrainzClient and DTOs
already live:
src-tauri/src/musicbrainz/location_discovery.rs
-> crates/qbz-integrations/src/musicbrainz/location.rs
src-tauri/src/musicbrainz/genre_normalization.rs
-> crates/qbz-integrations/src/musicbrainz/genre.rs
The functions exposed are unchanged: extract_metadata,
compute_affinity_score, build_scene_cache_key, format_life_span_date
(from location); normalize_genre, is_broad_genre, extract_affinity_seeds,
genre_summary (from genre). Imports in src-tauri/src/commands_v2/
integrations.rs are repointed to the new home; the legacy file
declarations are removed from src-tauri/src/musicbrainz/mod.rs. No
behavior change.
Unblocks the Slint side from reaching the same helpers via qbz-core
without depending on src-tauri.

reqwest default features included native-tls which pulled in
openssl-sys. This broke zigbuild cross-compilation because zig's
C compiler doesn't support the glibc version suffix for openssl
header expansion.
Fix: default-features = false on reqwest in workspace and
qbz-integrations (which had its own reqwest dep with defaults).
Now the entire daemon tree uses rustls-tls exclusively.

Three fixes:
- resolve_artist now prefers exact name matches over highest score,
fixing "The Warning" resolving to "Fates Warning" (score=100 but
wrong name vs score=97 exact match)
- resolve_area_country now returns ISO country code alongside name,
fixing flag display (was showing US flag for German artists)
- country_code updated in location metadata for correct flag rendering
cc
Add resolve_area_country() that walks the MB area hierarchy up to
the country level (e.g., Frankfurt -> Hessen -> Germany).
Use it in v2_musicbrainz_get_artist_metadata to get the real birth
country instead of MB's "country" field (which is where the artist
is active, not where they were born).
Hans Zimmer now shows "Frankfurt am Main, Germany" and clicking
the location shows German composers, not American ones.

ListenBrainz similar-artists returned mainstream crossover artists (SOAD,
Led Zeppelin for Metallica) instead of genre-accurate results. Now uses
MusicBrainz tag search to find artists sharing the seed's primary genre tag
(e.g. "thrash metal" returns Megadeth, Slayer, Kreator, etc).
- Add search_artists_by_tag to MusicBrainz client
- Deterministic shuffle using seed MBID hash for variety across artists
- Secondary tag fallback when primary yields fewer than 5 results
- Rename label to "You May Also Like", limit results to 6
- Add Last.fm get_similar_artists method (unused, for future use)
- Add tags field to ArtistFullResponse model
- Tighten local history exclusion to play_count > 2
- Allow dead_code on TokenValidationResponse.code (deserialized but not read)
- Remove unused MusicProvider import in commands_v2.rs
- Restore #[allow(non_snake_case)] on v2_plex_cache_get_tracks
- Replace drop(tokens) with let _ = tokens (drop on reference is no-op)
New crate for Last.fm, ListenBrainz, and MusicBrainz integrations.
Designed to work WITHOUT Tauri for TUI/headless clients.
Modules:
- lastfm: Scrobbling and now-playing via Cloudflare Workers proxy
- listenbrainz: Direct API client with user token auth
- musicbrainz: Entity resolution with rate limiting
Features:
- `cache` (default): SQLite persistence for offline support
- ListenBrainz: Credential storage, offline listen queue
- MusicBrainz: Resolved entity cache with TTL
Architecture:
- Pure async Rust, no Tauri dependencies
- Shared error types via IntegrationError enum
- Rate limiting for MusicBrainz (1 req/sec direct, faster via proxy)
