The scheduled-tick branch and the discover.requested one-shot branch
both read the same stale per-iteration config snapshot, so an enabled+due
sweep coinciding with a pending request ran discovery twice back-to-back
(idempotent but wasteful). Extract maybe_run_discovery, which unifies both
triggers into a single run and is now unit-tested.

autoMonitorFuture flagged any new release, so it could auto-monitor a
newly-released live album or compilation. Gate it on is_core_release so
auto-monitoring matches the studio-only default the UI shows.

Wrap the WatchedArtist.create + MonitoredRelease.createMany in a
$transaction so a mid-write failure can't leave a followed artist with
no releases (a state the 409 duplicate-follow guard would then wedge).

Each MB search result on /artists now links its name to
/discover/artist/[mbid] (the read-only disco + tracklist + own-state
preview), so you can preview before following there too — same wiring
the discovery feed already uses.

- preview-client want() no longer flips the Monitored badge when the POST fails
(deferred item #1 from the discovery-preview whole-branch review).
- README: discovery section notes the artist preview page.
- Plan Notes + project-state: TODO to reuse the preview page from the /artists
live search (wire artists-client.tsx hits to /discover/artist/[mbid]).

Follow-up to slice 3: a read-only artist preview page keyed by MBID, reachable from
suggested artists, suggested albums, and Find-similar results. Shows discography,
lazy per-album tracklists, own-state badges; Follow (reuse /api/artists) + Want
(new /api/discover/want upsert). Web-side MB reads only, no worker changes.

README: discovery status → done (ListenBrainz-native, no Spotify); off-by-default
note for the discovery sweep; architecture mentions MusicBrainz+ListenBrainz.
Plan: check off final verification (suites green, whole-branch review passed,
live-API algorithm fix), append the review's deferred items to Notes.

The placeholder algorithm string (contribution_5_threshold_15_limit_50) is not a
permitted enum member of the LB Labs endpoint — every lookup 400'd, making discovery
inert. Verified against the live API 2026-07-12: the days_7500/contribution_3/
threshold_10/limit_100 variant returns rows shaped {artist_mbid,name,comment,score},
which the existing defensive parser already handles. Fixed in both the worker adapter
and the web seed-search client (kept in sync).

Adds registry.build_similarity_sources() (always constructs
ListenBrainzSource; reachability is a per-run health() concern, not a
startup gate) and wires discovery into the worker's main loop: a
scheduled sweep gated on discover.enabled + DISCOVER_TICK_SECONDS, and
a one-shot discover.requested trigger mirroring the existing
scan.requested pattern.
Also hardens run_discovery's health-check pass: a source whose
health() raises is now logged and skipped instead of aborting the
whole sweep (accepted finding from the Task-3 review).

Spotify similarity/new-release APIs are dead for new apps (Nov 2024 + Feb 2026),
so discovery is built on ListenBrainz similar-artists (MBID-native) behind a
pluggable SimilaritySource interface. Manual review feed of similar artists +
albums; Follow/Want reuse slice-2 operations, Dismiss is permanent. Off by default.

MonitoredRelease rows created before an artist's discography was
populated (e.g. an owned album recorded before _populate_discography
ran) never got primaryType/secondaryTypes backfilled, wrongly
excluding them from the studio-only core view. _populate_discography
now DO UPDATEs the MB type metadata on conflict instead of DO NOTHING,
leaving monitored/state/currentQualityClass/firstGrabbedAt untouched.

Adds the per-artist release-type filter toggle: off (default) restricts
a discography view to core studio releases, on shows everything
(live, compilations, etc.).
A followed artist previously showed only the one owned album ("of 1")
because scan_library recorded just the resolved release. Now scan
browses each artist's full MusicBrainz release-group list once per
run and stores it as unmonitored MonitoredRelease rows, matching
web-follow behavior. The owned album keeps its monitored/fulfilled
state via ON CONFLICT DO NOTHING.
Type the POST request param (_request: Request) to match the test's
call signature and keep tsc --noEmit clean, per Next.js route handler
convention already used elsewhere in the codebase.
Probe each album exactly once and thread the ProbeResult through for
tags, quality, and format instead of hardcoding LibraryItem.format to
"FLAC" and re-probing on the tag-fallback path. Also skip album-level
directories starting with "." (previously only artist-level dirs were
skipped).
Adds the AudioProbe seam (probe.py, _probe.py MutagenProbe with a lazy
mutagen import, FakeAudioProbe) and scan_library, which walks /music,
resolves each album against MusicBrainz (falling back to embedded tags
when the folder name doesn't resolve), and idempotently records matched
albums as have (LibraryItem), monitored (MonitoredRelease, fulfilled),
and followed (WatchedArtist, autoMonitorFuture=false).

Test suites were running DELETE FROM.../deleteMany() against whatever
DATABASE_URL pointed to, which was the live app database, wiping user
credentials and library. Add a guard in both the worker conftest and
web test setup that raises before any cleanup unless the target DB
name ends in '_test'. Default DATABASE_URL to lyra_test when unset in
the worker, and make `npm test` target lyra_test explicitly.
