tracks.mbid was 100% NULL: the scanner only extracted album + artist
MBIDs, never the recording MBID. The ListenBrainz similarity worker is
gated on tracks.mbid IS NOT NULL, so track_similarity could never
populate — starving For-You/radio's strongest candidate source
(lb_similar) on every library.
- mbids.go: add extractRecordingMBID (mbz.Recording / Picard
musicbrainz_recordingid). Separate fn so extractMBIDs' signature +
unit tests stay untouched.
- scanner.go: persist recording MBID via UpsertTrack (heals on the
file_path conflict, so re-scans backfill for free).
- BackfillTrackMBIDs: one-shot pass mirroring BackfillMBIDs, wired as
scan Stage 2b (idempotent via SetTrackMbidIfNull, gated by
BackfillCap, log-only progress).
- migration 0029: tracks_mbid_unique (0002, written when the column
was always NULL) wrongly assumes one MBID == one track. A recording
appears on multiple releases, so rows legitimately share a recording
MBID. Replace with a non-unique partial index. Zero-risk: column is
100% NULL at migration time.

For-You silently vanished after ~7 days of not listening (seed query
required a non-skip play in the last 7 days) and capped at ~40 on
self-hosted libraries with no ListenBrainz similarity data.
- PickTopPlayedTracksForUser: tiered seed — last 30d top plays, else
all-time top plays, else liked tracks. For-You only disappears now
if the account has zero plays AND zero likes.
- produceForYou uses deeper candidate source limits (raised random/
tag/similar K) so it reaches ~100 even with empty lb_similar /
similar_artists; richer when LB enrichment is present.
- Rediscover: tiered — 6-month-dormant, else ≥5-play 30-day-dormant.
- On This Day: floor 60→30 days, window ±7→±10 doy; still skips
cleanly (no rows → no playlist) on insufficient history.

Headline of S4. "Shuffle all" is always present (home app-bar
shuffle icon); the pool degrades with reachability:
- online → GET /api/library/shuffle?limit=N (new): N random
library tracks server-side, per-user quarantine filtered
(ListRandomTracksForUser, ORDER BY random()).
- offline → ShuffleSource shuffles the whole local cache index
(audio_cache_index ∩ cached_tracks, names from cached_artists/
albums) — a UNION over liked AND recently-played, since the
two-bucket split is storage-only and never filters playback.
Offline gating: refreshable (singleton) system playlists need the
live build/shuffle endpoints, so their tile play is disabled when
offlineProvider is true — Shuffle all is the offline path. User
playlists still play from cache.
playlist_card now reads offlineProvider in build → wrapped the
direct-render widget test in ProviderScope (offlineProvider is
smoke-safe from S1: tracked timers, no connectivity mount).
S4b (offline Recently-played / Liked browsable surfaces over the
cache index) next.

Each is one candidate query + one registry entry; zero client work
(R2 made tiles/refresh/shuffle generic, all are singleton kinds so
web's server `refreshable` flag and Flutter's derived getter both
light up automatically).
- deep_cuts (#419): <=2-play tracks from liked / heavily-played
artists; diversity-capped.
- rediscover (#420): >=5-play tracks not heard in 6 months, by
historical affection.
- new_for_you (#421): tracks from albums added <=30d whose artist
the user likes/plays; album-coherent (no cap).
- on_this_day (#422): tracks played within ±7 day-of-year in prior
windows (>60d ago), weighted by play count.
- first_listens (#423): never-played albums, tiered liked-artist →
played-artist → rest; album-coherent.
system_mixes.go producers mirror the Discover model (SQL gives the
ranking; finishMix caps+truncates to 100 to match For-You/Discover
shuffle depth; album-coherent mixes skip the cap). Builder query
failure is non-fatal (logged, yields no playlist) like Discover.
Existing system_test existence checks are unaffected.
Closes the #411 system-playlists-v2 umbrella's new-types thread.

First of three stages for system-playlist sample-history dedup
(Fable #415, server-side rotation per the operator's choice).
Schema (migration 0027):
- play_events.source (nullable text): which surface a play came
from. 'for_you' / 'discover' feed rotation; NULL for library /
user-playlist / radio / Subsonic.
- system_playlist_rotation_state(user_id, playlist_kind,
played_track_ids uuid[], rotation_started_at, updated_at): the
per-(user,kind) set of already-heard tracks this rotation.
Ingest:
- New RecordPlayStartedWithSource on the writer; RecordPlayStarted
is now a thin source="" wrapper so the frozen Subsonic shim is
untouched (no signature ripple).
- When source is a known system kind, the same txn appends the
track to rotation state (AppendRotationPlayed keeps the array a
set via the conflict CASE).
- /api/events play_started accepts an optional "source".
No serve-behavior change yet — Stage 2 makes shuffle prefer the
unplayed tail + resets on exhaustion; Stage 3 wires the clients to
send source and consume the rotation-aware order.
Tests: rotation appends + dedupes for a system source; source-less
play writes no rotation row. (Existing RecordPlayStarted tests are
unchanged — same wrapper signature, identical behavior at source="".)

Closes the last deferred follow-up from #357. The library_changes
table is the append-only change log that drives /api/library/sync's
delta semantics — every mutation (scanner upsert, like, playlist
edit, track delete) writes one row. Without a retention policy the
table grows unbounded; the original migration (0025) called out the
follow-up explicitly.
New goroutine: sync.Compactor runs daily, deletes rows where
changed_at < now - 30 days. Logs a row count when non-zero so
operators can see compaction activity in the journal. First tick
fires on startup so a process that hasn't been compacted in a
while catches up immediately.
30-day retention matches the offline-mode spec
(docs/superpowers/specs/2026-05-09-flutter-offline-mode-design.md).
Clients with a cursor older than that hit the existing 410 fallback
path and resync from scratch.
Imported as syncpkg in main.go to follow the existing convention
(see internal/library/scanner.go).

Schema + endpoint scaffolding for #392 Half B (per-user timezone
scheduling). Adds two columns to the users table:
- timezone text NOT NULL DEFAULT 'UTC' (IANA name)
- timezone_updated_at timestamptz (nullable; populated on each PUT)
PUT /api/me/timezone validates the IANA value via time.LoadLocation
and writes the row. No scheduler integration yet — the scheduler
struct lands in the next commit and the handler-side Refresh call
in the commit after.

For-You + Songs-Like-X seed selection moves to Go-side daily rotation
(next commit). The SQL change just widens the candidate pool: top-5
played tracks instead of single top played track; top-5 artists
instead of top-3.

The cross-user bucket query combined SELECT DISTINCT with ORDER BY md5(...),
which Postgres rejects at plan time (SQLSTATE 42P10). buildDiscoverCandidates
returned that error on first bucket failure, so the whole Discover playlist
was skipped every nightly run — even though the random bucket pool was
healthy. Switched to GROUP BY so the md5 ordering expression no longer needs
to appear in the select list, and hardened the function so future single-
bucket failures degrade gracefully via slot redistribution instead of taking
out the whole playlist.

handleGetHome itself is well-architected (5 sections in parallel via
goroutines, latency-bound by the slowest single query). The cold-
start lag is two of those queries doing wider scans than necessary.
ListLastPlayedArtistsForUser was iterating FROM artists a with a
LATERAL play_events join per row — O(total_artists in library) plan
even for users who've only played a handful. Inverted: aggregate the
user's plays by artist_id first via the play_events → tracks join
(uses play_events_user_track_idx + tracks pkey), then attach the
artist row and lateral cover/count subqueries only for the artists
that actually appear. Cost now bounded by play history, not library
size.
ListMostPlayedTracksForUser was joining tracks/albums/artists for
every play_event row before grouping — O(total plays) work for
joins. Pre-aggregated play_events into a CTE keyed by track_id +
count(*), then joined to tracks/albums/artists only for the
distinct-tracks survivors. Order-by uses the pre-computed count.
No handler or generated-Go signature changes — both queries return
the same rowset shape, just much faster on libraries where total
artists/plays >> distinct-played-artists/distinct-played-tracks.
Two new sqlc queries replace three sequential per-album round trips
that were dominating detail-screen latency.
GetAlbumWithArtist: handleGetAlbum was doing GetAlbumByID then
GetArtistByID — separate round trips for one logical lookup. The new
query joins albums + artists with sqlc.embed and returns both in one
SELECT. Detail-page DB cost: 3 trips → 2.
ListAlbumsByArtistWithTrackCount: handleGetArtist was loading the
artist's album list, then issuing one CountTracksByAlbum per album to
populate track_count. On a 30-album artist that's 32 sequential
queries — each ~5ms over a local DB, ~30ms over a remote one. The
new query embeds the album row + a correlated count(*) subquery, so
every album's track count comes back in one SELECT regardless of
album count. Detail-page DB cost: 1 + N → 1 + 1.
Together these account for the bulk of cold-cache navigation latency
on the Flutter client. Combined with the existing SWR + nav
hydration on the client side, detail screens should render their
header instantly and the body within one round trip instead of
N+constant.
Returns batched upserts + deletes since the supplied cursor. Empty cursor
returns full snapshot; subsequent calls pull deltas. Per-user entities
(likes, playlists) are scoped to the authed user. Composite-key entities
(likes, playlist_tracks) use stable string ids encoded by sync.EncodeLikeID
/ sync.EncodePlaylistTrackID.
Behavior:
204 No Content - no changes since cursor
200 OK - JSON syncResponse {cursor, upserts, deletes}
410 Gone - cursor older than oldest log row; client must reset
401 / 500 - standard envelope errors
Adds sqlc queries GetAlbumsByIDs, GetTracksByIDs, GetPlaylistsByIDs to
mirror the existing GetArtistsByIDs.

Append-only change log for library entities. Every mutation on

Adds users.email (optional, lowercase-unique via partial index),
smtp_config singleton, and password_resets tokens. Plus the
queries U3-T2 / T3 / T4 use:
- ChangeUserPassword: self-service password change. HTTP layer
verifies the current password before this fires.
- UpdateUserProfile: set display_name + email together.
- RegenerateApiToken: invalidate old API token.
- GetUserByEmail: case-insensitive lookup for forgot-password.
- GetSMTPConfig + UpdateSMTPConfig: admin SMTP settings CRUD.
- CreatePasswordReset / GetPasswordReset / UsePasswordReset
(:execrows for atomic claim) / DeleteExpiredPasswordResets
(cron-style cleanup, not yet wired).
Email column is nullable; users without email have admin-reset
as their only password-recovery path. The lower() unique index
allows many NULLs and prevents case-insensitive duplicates.

Four new admin endpoints under existing RequireAdmin middleware:
- POST /api/admin/users — admin-creates-user. Body
{username, password, display_name?, is_admin?}. Same username
+ password validation as the public /register handler. 409
on duplicate. Audits ActionCreateUserAdmin.
- DELETE /api/admin/users/{id} — hard delete. Last-admin guard
refuses delete when target is the only admin (409). Schema's
ON DELETE CASCADE on user-FK tables handles plays/likes/
sessions cleanup. Audits ActionDeleteUser with target's
username + was_admin flag.
- POST /api/admin/users/{id}/reset-password — body
{password}. 8-char minimum. Admin sets a new password
without knowing the old one. Audits ActionPasswordResetAdmin.
- PUT /api/admin/users/{id}/auto-approve — body
{auto_approve: bool}. Toggles the per-user flag added in T1
(the #355 sub-feature surface). Audits ActionAutoApproveToggle.
adminUserView shape extended with auto_approve_requests so the
list and toggle responses carry the flag. ListUsers SQL query
updated to include auto_approve_requests; generated Go updated
to match. Tests cover happy paths, last-admin guard on delete,
password validation, duplicate username, and the auto-approve
round-trip.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds users.auto_approve_requests boolean default false (the #355
sub-feature surface; the request-flow handler that honors this
flag is U2.5 follow-up work).
Four new sqlc queries for the U2 admin endpoints:
- CreateUserAdmin: admin-driven user creation, accepts all five
fields explicitly.
- DeleteUser: hard delete; schema's ON DELETE CASCADE foreign
keys handle plays/likes/sessions cleanup. Last-admin guard
lives in the HTTP layer (next task).
- ResetUserPassword: admin sets a new hashed password without
knowing the old one.
- UpdateUserAutoApprove: toggles the new boolean.
Self-service equivalents (knows-current-password change, etc.)
are U3 work and use distinct queries.
Five admin endpoints under existing RequireAdmin middleware:
- GET /api/admin/invites — list active + recently-redeemed
- POST /api/admin/invites — generate 24h invite, returns
{token, expires_at, ...}. Audits ActionInviteCreate.
- DELETE /api/admin/invites/{token} — revoke unredeemed invite.
Audits ActionInviteRevoke.
- GET /api/admin/users — list all users (id, username,
display_name, is_admin, created_at).
- PUT /api/admin/users/{id}/admin — toggle is_admin with
last-admin guard. Audits ActionPromoteAdmin / ActionDemoteAdmin.
Last-admin guard counts admins, refuses demotion of the sole
admin with 409 'last_admin'. Race window between count and update
is acceptable for v1 — worst case is 'no admins left,' which the
env-driven bootstrap or CLI reset can recover from. Common path
('admin demotes themselves') is now blocked.
Adds ListUsers, CountAdmins, UpdateUserAdmin sqlc queries to
users.sql.
Tests cover: invite create/list/delete round-trip, non-admin gets
403, user list, promote happy path, last-admin demotion refused,
two-admins demotion allowed.

Schema for user management U1: display_name on users; user_invites;
registration_settings singleton (default 'invite_only'); audit_log.
Plus the internal/audit package centralizing the action-name
vocabulary and JSON metadata marshaling so handlers don't repeat
boilerplate.
Race-safe first-admin uses a query-shape primitive
(CreateUserFirstAdminRace's WHERE NOT EXISTS subquery) rather than
a schema-level constraint. Concurrent empty-state registrations
both see 'no users yet' and both insert as admin — fine, having
two admins from the start is benign; what matters is at-least-one.
users.username uniqueness arbitrates if the two callers picked the
same username.
CreateUser signature gains display_name (nullable); existing
bootstrap call sites pass nil. The audit package declares the full
U1+U2+U3 action vocabulary upfront so subsequent slices are purely
additive on the caller side.
Tests cover audit Write with + without metadata and that every
declared action constant persists correctly.

POST /api/playlists/system/discover/refresh re-runs the system
playlist build synchronously for the calling user, then returns
their newly-built Discover playlist's UUID and track count.
Used by the frontend's "Refresh" affordances (next task) on the
Discover detail page header and the home Playlists row tile kebab.
Operator's escape hatch when they want a different randomness
without waiting for tomorrow's cron tick (e.g., after pasting a
Last.fm key, after the daily cover-art enrichment expanded their
playable library, or just for the heck of it).
Authenticated user only; the authed sub-router's RequireUser
middleware handles 401. Each user refreshes only their own
Discover — no admin route, no cross-user impersonation.
Adds GetSystemPlaylistByVariantForUser sqlc query for the response
lookup. Returns playlist_id=null and track_count=0 if the build
succeeded but the user's library yielded no eligible tracks
(degenerate empty-library).
Adds 'discover' as an accepted system_variant on the playlists
table — alongside 'for_you' and 'songs_like_artist' — and three
sqlc bucket queries that back the new playlist's daily candidate
selection.
The three buckets surface tracks the user hasn't played and
hasn't liked:
- Dormant artists: artists this user has played < 10 times total.
Surfaces the long tail of their library.
- Cross-user likes: tracks any OTHER user has liked but this one
hasn't engaged with. Empty on single-user servers; the Go-side
allocator redistributes the deficit across the other two
buckets.
- Random unheard: pure random sample as the safety net and the
cold-start fallback.
All three share exclusion filters: not-played by this user, not
liked by this user, not in lidarr_quarantine for this user. All
order by md5(track_id || dateStr) for daily determinism — same
pattern as the existing tieBreakHash logic in system.go.
LIMIT values are generous (80/60/200) so the per-album (<=2) /
per-artist (<=3) caps and slot redistribution in T2 have headroom.

Changes the AlbumCoverProvider and ArtistArtProvider interfaces from
MBID-only string parameters to ref-struct signatures so name-based
providers (Deezer, Last.fm in upcoming tasks) can act on rows
without MBIDs.
Today, 53 of 213 artists in the dev DB have NULL MBIDs — featured
artists, remixers, and compilation contributors created from
track-tag splits where the primary-artist MBID is in the file but
collaborator IDs aren't. These rows are unreachable by the current
MBID-only chain. Refactoring the interface unblocks future
name-based providers from acting on them.
TheAudioDB and MBCAA keep MBID-only behavior internally: they return
ErrNotFound when ref.MBID is empty rather than attempting a
name-based fallback. The MBID guard inside EnrichAlbum/EnrichArtist
is removed; providers receive the ref unconditionally and decide
whether they can act on it.
GetAlbumWithFirstTrackPath now JOINs artists to return artist_name
alongside the existing fields, supporting AlbumRef construction.
No behavioral change today (only TheAudioDB + MBCAA registered, both
keep MBID-only behavior). The change unblocks T3 (Deezer) and T4
(Last.fm) which can now register and act on every artist/album
regardless of MBID presence.

Relaxes the artists/albums art_source CHECK constraints to allow the
new 'deezer' and 'lastfm' source values alongside the existing
accepted set. Adds cover_art_sources_meta.last_registered_providers_hash
for the boot-time auto-bump detection: when the registered-provider
set changes between deploys, we bump current_version once so 'none'
rows become eligible for retry against the new chain.
Two sqlc queries added: GetCoverArtProvidersHash reads the stored
hash; BumpVersionAndSetProvidersHash atomically increments the
version and stores a new hash, returning the new version. Both used
by the boot logic in a later task.
Adds the singleton scan_schedule table holding the operator's
recurring-scan config. mode is the discriminator (off/interval/
daily/weekly); CHECK constraints enforce per-mode field validity
(interval_hours required for interval; time_of_day for daily and
weekly; weekly_day 1..7 for weekly). Seed row is mode='off'.
Two new queries: GetScanSchedule (read singleton; used by scheduler
boot + admin GET) and UpdateScanSchedule (admin PATCH; application
normalizes per-mode fields to NULL when mode='off').
Three failures from the prior push:
1. internal/api/library.go and 3 other callers of q.GetArtistByID
broke because T2 modified the query to use an explicit column
list, making sqlc generate GetArtistByIDRow instead of returning
dbq.Artist. dbq.Artist already has every column added by
migration 0018 (artist_thumb_path / artist_fanart_path /
artist_art_source / artist_art_sources_version), so the explicit
column list was unnecessary work. Revert the SELECT to SELECT *,
regenerate sqlc, GetArtistByIDRow disappears, all callers compile
again.
2. internal/tracks/service_test.go missed the dataDir parameter
added to NewService in T9. Add "" as the 4th arg to every test
call site (tests don't exercise the artist-art cleanup path; the
empty dataDir is fine).
3. integrations.test.ts:356's mock.calls.filter callback had a
too-narrow type annotation that svelte-check rejected. Relax to
any[] to match what mock.calls actually is.
Adds an artist-art-enrich stage after cover-enrich in RunScan. The
stage drains EnrichArtistBatch with a configurable cap and the
operator's data_dir, persists processed/succeeded/failed tallies to
the scan_runs.artist_art_enrich jsonb column added in migration
0018.
The admin /admin Library Scan card grid expands from 3 to 4 columns
with the new "Artist art" card mirroring the cover-enrichment one
(Processed / Succeeded / Failed). The TS ScanStatus type gains an
optional artist_art_enrich field. The Go scanStatusResp gains the
matching ArtistArtEnrich json.RawMessage field.
cmd/minstrel/main.go (and admin scan-trigger handler) wire the new
RunScanConfig fields: ArtistEnrichCap reuses cfg.Library.CoverArtBackfillCap
for now (can be split if separate budgets are useful), DataDir is
cfg.Storage.DataDir.

- Extends GetAlbumCoverageRollup's with_art FILTER to include
'theaudiodb' so F's coverage gauge surfaces TheAudioDB-found rows
as with_art rather than silently undercounting.
- Modifies ListAlbumsMissingCover to take the current sources_version
as a parameter; eligibility now includes stale-'none' rows.
- Adds SetAlbumCoverWithVersion (atomic write of path + source +
version stamp) and the parallel SetArtistArtWithVersion +
ClearArtistArtNone + ListArtistsMissingArt for the artist-art
enricher.
- New coverart_settings.sql with ListProviderSettings,
UpsertProviderSettings (boot reconciliation, preserves operator
values on conflict), UpdateProviderSettings (admin PATCH; tri-
state api_key handling), GetCurrentSourcesVersion,
BumpSourcesVersion (RETURNING the new value).
Code-review polish on GetAlbumCoverageRollup's comment block:
- Records the invariant that with_art + pending + settled = total
(and that pending_no_mbid is a subset of pending, not a fourth
bucket).
- Notes that the IN ('sidecar','embedded','mbcaa') list must stay
in sync with the cover_art_source CHECK constraint in migration
0016 — without this note a future source addition could silently
undercount with_art.
FILTER-aggregate count over albums.cover_art_source and albums.mbid
returning total, with_art, pending, settled, pending_no_mbid in a
single round-trip. Sub-millisecond on realistic libraries; no index
needed for v1. pending_no_mbid is a subset of pending — the UI
tooltip uses it to show how many "pending" rows are blocked on
missing MBID and won't be moved by another scan.
Also bumps the Makefile sqlc pin from 1.27.0 to 1.31.1 to match the
version that produced all existing committed dbq/*.go files. The
prior pin was stale; running make generate against 1.27.0 silently
rolled the codegen back (cosmetic version headers on most files
plus a real codegen shape change in DeleteArtistIfEmpty).
Adds a boot-time goroutine that walks albums with NULL mbid, re-reads
tags from one track per album via dhowden/tag, and persists album + artist
MBIDs. Healed albums also get their cover_art_source='none' cleared so the
enricher's next batch retries the MBCAA fetch. Caps at 5000 albums per
boot to avoid stalling startup on huge libraries.

Production list-playlists handler reuses Service.List + in-memory kind
filter so other users' public playlists can surface alongside the
caller's filtered own. Comment clarifies the divergence so future
readers don't expect this query to be wired into the API path.
Adds internal/db/queries/system_playlists.sql with 12 named queries
covering active-user enumeration, per-user run tracking (claim/finish/fail),
seed-artist/track/cover selection, and playlist CRUD by kind.
Runs sqlc generate to emit dbq/system_playlists.sql.go; also updates
playlists.sql.go and models.go to reflect the new kind/system_variant/
seed_artist_id columns added in migration 0015.
Note: plan specified a.cover_path for PickTopAlbumCoverForArtistByUser
but albums uses cover_art_path — corrected in the query file.

Migration 0014 adds playlists + playlist_tracks. track_id is nullable
with ON DELETE SET NULL — tracks can be removed from the library
without silently dropping playlist entries; the denormalized snapshot
(title/artist/album/duration) keeps the row legible afterwards. UI
renders such rows greyed-out.
Indexes: playlists by (user_id, updated_at DESC) and a partial public
index for cross-user discovery; playlist_tracks partial index on
track_id to support the FK SET NULL lookup.
Queries provide CRUD + rollup recompute (track_count, duration_sec)
+ append/remove primitives. Reorder is service-layer orchestrated via
raw tx.Exec; no SQL primitive needed.
DeleteTrack returns album_id + artist_id so the calling service can
chain the album-empty / artist-empty cascade. DeleteAlbumIfEmpty and
DeleteArtistIfEmpty are no-ops when other rows still reference the
parent — the service treats pgx.ErrNoRows as "not orphaned, skip".
After Lidarr accepts a request the local reconciler imports albums and
tracks as they arrive — but until the request hit 'completed' the
operator had no way to see "is anything happening?" The /requests and
/admin/requests rows now surface a live progress line whenever the
request's matched entity has children in our library.
Backend:
- New CountAlbumsByArtist + CountTracksByArtist sqlc queries.
- requestView gains imported_album_count and imported_track_count.
- New fillProgress helper computes them from the matched entity:
- kind=artist → counts albums + tracks under matched_artist_id
- kind=album → counts tracks under matched_album_id
- kind=track → 1 once matched_track_id is set
N+1 in the list endpoints; acceptable at admin scale.
- handleListRequests, handleGetRequest, and handleListAdminRequests
populate the new fields on every response.
Frontend:
- LidarrRequest TS type extended with the two counters.
- Both the operator's /requests page and the admin /admin/requests
page render an accent-colored line under the row meta when at
least one counter is non-zero, e.g.:
Artist: "5 albums · 47 tracks ingested"
Album: "12 tracks ingested"
Track: "Track ingested"
- Updated test fixtures to include the new required fields.

Persists the operator's metadata-profile choice alongside quality
profile + root folder. Defaults to the first profile Lidarr returns
(usually 'Standard' on a vanilla install) so the common case is
zero-click; operators with custom profiles like 'Singles only' can pick
explicitly.
Backend:
- Migration 0013: adds nullable default_metadata_profile_id to
lidarr_config. Existing rows get NULL and the service falls back to
fetch-and-pick-first until they save.
- Updated lidarr_config queries + sqlc + lidarrconfig.Config + admin
view/put body to round-trip the new field.
- handlePutLidarrConfig requires it (along with QP and root folder)
when enabled=true — matches the existing missing_defaults gate.
- New GET /api/admin/lidarr/metadata-profiles handler + lidarr.Client
ListMetadataProfiles (GET /api/v1/metadataprofile, same shape as
the quality-profile endpoint).
- lidarrrequests.Approve prefers cfg.DefaultMetadataProfileID; falls
back to the fetch-list path only when 0 (back-compat for upgraders).
Frontend:
- LidarrConfig type + LidarrMetadataProfile type + qk.lidarrMetadataProfiles.
- listMetadataProfiles + createMetadataProfilesQuery client helpers.
- Integrations page: third <select> picker, auto-defaults to first

Add per-user artist-suggestion service ranking out-of-library MBIDs by
signal x similarity. Single-CTE SQL collects user likes (5x weight) and
recency-decayed plays, joins against artist_similarity_unmatched, and
filters in-library candidates plus non-terminal lidarr_requests. The
service resolves top-3 attribution seeds to artist names in a batched
GetArtistsByIDs call so the UI can render "because you liked X" reasons.

- Composite PK (user_id, track_id) already serves WHERE user_id queries;
the secondary (user_id, created_at DESC) index just amplified writes.
- ListQuarantineForUser now selects only the joined fields the SPA card
actually renders (~10 columns) rather than embedding three full structs
(~35 columns); halves wire/DB bandwidth before consumers exist.
- max(q.created_at)::timestamptz cast emits pgtype.Timestamptz instead of
interface{} so handlers can read latest_at without a type-assert.
